Even though ISA is more or less dead today the LPC bus +uses the same DMA system so it will be around for quite some time. + +Part I - Headers and dependencies +--------------------------------- + +To do ISA style DMA you need to include two headers: + +#include +#include + +The first is the generic DMA API used to convert virtual addresses to +physical addresses (see Documentation/DMA-API.txt for details). + +The second contains the routines specific to ISA DMA transfers. Since +this is not present on all platforms make sure you construct your +Kconfig to be dependent on ISA_DMA_API (not ISA) so that nobody tries +to build your driver on unsupported platforms. + +Part II - Buffer allocation +--------------------------- + +The ISA DMA controller has some very strict requirements on which +memory it can access so extra care must be taken when allocating +buffers. + +(You usually need a special buffer for DMA transfers instead of +transferring directly to and from your normal data structures.) + +The DMA-able address space is the lowest 16 MB of _physical_ memory. +Also the transfer block may not cross page boundaries (which are 64 +or 128 KiB depending on which channel you use). + +In order to allocate a piece of memory that satisfies all these +requirements you pass the flag GFP_DMA to kmalloc. + +Unfortunately the memory available for ISA DMA is scarce so unless you +allocate the memory during boot-up it's a good idea to also pass +__GFP_REPEAT and __GFP_NOWARN to make the allocater try a bit harder. + +(This scarcity also means that you should allocate the buffer as +early as possible and not release it until the driver is unloaded.) + +Part III - Address translation +------------------------------ + +To translate the virtual address to a physical use the normal DMA +API. Do _not_ use isa_virt_to_phys() even though it does the same +thing. The reason for this is that the function isa_virt_to_phys() +will require a Kconfig dependency to ISA, not just ISA_DMA_API which +is really all you need. Remember that even though the DMA controller +has its origins in ISA it is used elsewhere. + +Note: x86_64 had a broken DMA API when it came to ISA but has since +been fixed. If your arch has problems then fix the DMA API instead of +reverting to the ISA functions. + +Part IV - Channels +------------------ + +A normal ISA DMA controller has 8 channels. The lower four are for +8-bit transfers and the upper four are for 16-bit transfers. + +(Actually the DMA controller is really two separate controllers where +channel 4 is used to give DMA access for the second controller (0-3). +This means that of the four 16-bits channels only three are usable.) + +You allocate these in a similar fashion as all basic resources: + +extern int request_dma(unsigned int dmanr, const char * device_id); +extern void free_dma(unsigned int dmanr); + +The ability to use 16-bit or 8-bit transfers is _not_ up to you as a +driver author but depends on what the hardware supports. Check your +specs or test different channels. + +Part V - Transfer data +---------------------- + +Now for the good stuff, the actual DMA transfer. :) + +Before you use any ISA DMA routines you need to claim the DMA lock +using claim_dma_lock(). The reason is that some DMA operations are +not atomic so only one driver may fiddle with the registers at a +time. + +The first time you use the DMA controller you should call +clear_dma_ff(). This clears an internal register in the DMA +controller that is used for the non-atomic operations. As long as you +(and everyone else) uses the locking functions then you only need to +reset this once. + +Next, you tell the controller in which direction you intend to do the +transfer using set_dma_mode(). Currently you have the options +DMA_MODE_READ and DMA_MODE_WRITE. + +Set the address from where the transfer should start (this needs to +be 16-bit aligned for 16-bit transfers) and how many bytes to +transfer. Note that it's _bytes_. The DMA routines will do all the +required translation to values that the DMA controller understands. + +The final step is enabling the DMA channel and releasing the DMA +lock. + +Once the DMA transfer is finished (or timed out) you should disable +the channel again. You should also check get_dma_residue() to make +sure that all data has been transfered. + +Example: + +int flags, residue; + +flags = claim_dma_lock(); + +clear_dma_ff(); + +set_dma_mode(channel, DMA_MODE_WRITE); +set_dma_addr(channel, phys_addr); +set_dma_count(channel, num_bytes); + +dma_enable(channel); + +release_dma_lock(flags); + +while (!device_done()); + +flags = claim_dma_lock(); + +dma_disable(channel); + +residue = dma_get_residue(channel); +if (residue != 0) + printk(KERN_ERR "driver: Incomplete DMA transfer!" + " %d bytes left!\n", residue); + +release_dma_lock(flags); + +Part VI - Suspend/resume +------------------------ + +It is the driver's responsibility to make sure that the machine isn't +suspended while a DMA transfer is in progress. Also, all DMA settings +are lost when the system suspends so if your driver relies on the DMA +controller being in a certain state then you have to restore these +registers upon resume. diff --git a/Documentation/DocBook/journal-api.tmpl b/Documentation/DocBook/journal-api.tmpl index 1ef6f43c6d8f..341aaa4ce481 100644 --- a/Documentation/DocBook/journal-api.tmpl +++ b/Documentation/DocBook/journal-api.tmpl @@ -116,7 +116,7 @@ filesystem.

RCU OVERVIEW + +The basic idea behind RCU is to split updates into "removal" and +"reclamation" phases. The removal phase removes references to data items +within a data structure (possibly by replacing them with references to +new versions of these data items), and can run concurrently with readers. +The reason that it is safe to run the removal phase concurrently with +readers is the semantics of modern CPUs guarantee that readers will see +either the old or the new version of the data structure rather than a +partially updated reference. The reclamation phase does the work of reclaiming +(e.g., freeing) the data items removed from the data structure during the +removal phase. Because reclaiming data items can disrupt any readers +concurrently referencing those data items, the reclamation phase must +not start until readers no longer hold references to those data items. + +Splitting the update into removal and reclamation phases permits the +updater to perform the removal phase immediately, and to defer the +reclamation phase until all readers active during the removal phase have +completed, either by blocking until they finish or by registering a +callback that is invoked after they finish. Only readers that are active +during the removal phase need be considered, because any reader starting +after the removal phase will be unable to gain a reference to the removed +data items, and therefore cannot be disrupted by the reclamation phase. + +So the typical RCU update sequence goes something like the following: + +a. Remove pointers to a data structure, so that subsequent + readers cannot gain a reference to it. + +b. Wait for all previous readers to complete their RCU read-side + critical sections. + +c. At this point, there cannot be any readers who hold references + to the data structure, so it now may safely be reclaimed + (e.g., kfree()d). + +Step (b) above is the key idea underlying RCU's deferred destruction. +The ability to wait until all readers are done allows RCU readers to +use much lighter-weight synchronization, in some cases, absolutely no +synchronization at all. In contrast, in more conventional lock-based +schemes, readers must use heavy-weight synchronization in order to +prevent an updater from deleting the data structure out from under them. +This is because lock-based updaters typically update data items in place, +and must therefore exclude readers. In contrast, RCU-based updaters +typically take advantage of the fact that writes to single aligned +pointers are atomic on modern CPUs, allowing atomic insertion, removal, +and replacement of data items in a linked structure without disrupting +readers. Concurrent RCU readers can then continue accessing the old +versions, and can dispense with the atomic operations, memory barriers, +and communications cache misses that are so expensive on present-day +SMP computer systems, even in absence of lock contention. + +In the three-step procedure shown above, the updater is performing both +the removal and the reclamation step, but it is often helpful for an +entirely different thread to do the reclamation, as is in fact the case +in the Linux kernel's directory-entry cache (dcache). Even if the same +thread performs both the update step (step (a) above) and the reclamation +step (step (c) above), it is often helpful to think of them separately. +For example, RCU readers and updaters need not communicate at all, +but RCU provides implicit low-overhead communication between readers +and reclaimers, namely, in step (b) above. + +So how the heck can a reclaimer tell when a reader is done, given +that readers are not doing any sort of synchronization operations??? +Read on to learn about how RCU's API makes this easy. + + +2. WHAT IS RCU'S CORE API? + +The core RCU API is quite small: + +a. rcu_read_lock() +b. rcu_read_unlock() +c. synchronize_rcu() / call_rcu() +d. rcu_assign_pointer() +e. rcu_dereference() + +There are many other members of the RCU API, but the rest can be +expressed in terms of these five, though most implementations instead +express synchronize_rcu() in terms of the call_rcu() callback API. + +The five core RCU APIs are described below, the other 18 will be enumerated +later. See the kernel docbook documentation for more info, or look directly +at the function header comments. + +rcu_read_lock() + + void rcu_read_lock(void); + + Used by a reader to inform the reclaimer that the reader is + entering an RCU read-side critical section. It is illegal + to block while in an RCU read-side critical section, though + kernels built with CONFIG_PREEMPT_RCU can preempt RCU read-side + critical sections. Any RCU-protected data structure accessed + during an RCU read-side critical section is guaranteed to remain + unreclaimed for the full duration of that critical section. + Reference counts may be used in conjunction with RCU to maintain + longer-term references to data structures. + +rcu_read_unlock() + + void rcu_read_unlock(void); + + Used by a reader to inform the reclaimer that the reader is + exiting an RCU read-side critical section. Note that RCU + read-side critical sections may be nested and/or overlapping. + +synchronize_rcu() + + void synchronize_rcu(void); + + Marks the end of updater code and the beginning of reclaimer + code. It does this by blocking until all pre-existing RCU + read-side critical sections on all CPUs have completed. + Note that synchronize_rcu() will -not- necessarily wait for + any subsequent RCU read-side critical sections to complete. + For example, consider the following sequence of events: + + CPU 0 CPU 1 CPU 2 + ----------------- ------------------------- --------------- + 1. rcu_read_lock() + 2. enters synchronize_rcu() + 3. rcu_read_lock() + 4. rcu_read_unlock() + 5. exits synchronize_rcu() + 6. rcu_read_unlock() + + To reiterate, synchronize_rcu() waits only for ongoing RCU + read-side critical sections to complete, not necessarily for + any that begin after synchronize_rcu() is invoked. + + Of course, synchronize_rcu() does not necessarily return + -immediately- after the last pre-existing RCU read-side critical + section completes. For one thing, there might well be scheduling + delays. For another thing, many RCU implementations process + requests in batches in order to improve efficiencies, which can + further delay synchronize_rcu(). + + Since synchronize_rcu() is the API that must figure out when + readers are done, its implementation is key to RCU. For RCU + to be useful in all but the most read-intensive situations, + synchronize_rcu()'s overhead must also be quite small. + + The call_rcu() API is a callback form of synchronize_rcu(), + and is described in more detail in a later section. Instead of + blocking, it registers a function and argument which are invoked + after all ongoing RCU read-side critical sections have completed. + This callback variant is particularly useful in situations where + it is illegal to block. + +rcu_assign_pointer() + + typeof(p) rcu_assign_pointer(p, typeof(p) v); + + Yes, rcu_assign_pointer() -is- implemented as a macro, though it + would be cool to be able to declare a function in this manner. + (Compiler experts will no doubt disagree.) + + The updater uses this function to assign a new value to an + RCU-protected pointer, in order to safely communicate the change + in value from the updater to the reader. This function returns + the new value, and also executes any memory-barrier instructions + required for a given CPU architecture. + + Perhaps more important, it serves to document which pointers + are protected by RCU. That said, rcu_assign_pointer() is most + frequently used indirectly, via the _rcu list-manipulation + primitives such as list_add_rcu(). + +rcu_dereference() + + typeof(p) rcu_dereference(p); + + Like rcu_assign_pointer(), rcu_dereference() must be implemented + as a macro. + + The reader uses rcu_dereference() to fetch an RCU-protected + pointer, which returns a value that may then be safely + dereferenced. Note that rcu_deference() does not actually + dereference the pointer, instead, it protects the pointer for + later dereferencing. It also executes any needed memory-barrier + instructions for a given CPU architecture. Currently, only Alpha + needs memory barriers within rcu_dereference() -- on other CPUs, + it compiles to nothing, not even a compiler directive. + + Common coding practice uses rcu_dereference() to copy an + RCU-protected pointer to a local variable, then dereferences + this local variable, for example as follows: + + p = rcu_dereference(head.next); + return p->data; + + However, in this case, one could just as easily combine these + into one statement: + + return rcu_dereference(head.next)->data; + + If you are going to be fetching multiple fields from the + RCU-protected structure, using the local variable is of + course preferred. Repeated rcu_dereference() calls look + ugly and incur unnecessary overhead on Alpha CPUs. + + Note that the value returned by rcu_dereference() is valid + only within the enclosing RCU read-side critical section. + For example, the following is -not- legal: + + rcu_read_lock(); + p = rcu_dereference(head.next); + rcu_read_unlock(); + x = p->address; + rcu_read_lock(); + y = p->data; + rcu_read_unlock(); + + Holding a reference from one RCU read-side critical section + to another is just as illegal as holding a reference from + one lock-based critical section to another! Similarly, + using a reference outside of the critical section in which + it was acquired is just as illegal as doing so with normal + locking. + + As with rcu_assign_pointer(), an important function of + rcu_dereference() is to document which pointers are protected + by RCU. And, again like rcu_assign_pointer(), rcu_dereference() + is typically used indirectly, via the _rcu list-manipulation + primitives, such as list_for_each_entry_rcu(). + +The following diagram shows how each API communicates among the +reader, updater, and reclaimer. + + + rcu_assign_pointer() + +--------+ + +---------------------->| reader |---------+ + | +--------+ | + | | | + | | | Protect: + | | | rcu_read_lock() + | | | rcu_read_unlock() + | rcu_dereference() | | + +---------+ | | + | updater |<---------------------+ | + +---------+ V + | +-----------+ + +----------------------------------->| reclaimer | + +-----------+ + Defer: + synchronize_rcu() & call_rcu() + + +The RCU infrastructure observes the time sequence of rcu_read_lock(), +rcu_read_unlock(), synchronize_rcu(), and call_rcu() invocations in +order to determine when (1) synchronize_rcu() invocations may return +to their callers and (2) call_rcu() callbacks may be invoked. Efficient +implementations of the RCU infrastructure make heavy use of batching in +order to amortize their overhead over many uses of the corresponding APIs. + +There are no fewer than three RCU mechanisms in the Linux kernel; the +diagram above shows the first one, which is by far the most commonly used. +The rcu_dereference() and rcu_assign_pointer() primitives are used for +all three mechanisms, but different defer and protect primitives are +used as follows: + + Defer Protect + +a. synchronize_rcu() rcu_read_lock() / rcu_read_unlock() + call_rcu() + +b. call_rcu_bh() rcu_read_lock_bh() / rcu_read_unlock_bh() + +c. synchronize_sched() preempt_disable() / preempt_enable() + local_irq_save() / local_irq_restore() + hardirq enter / hardirq exit + NMI enter / NMI exit + +These three mechanisms are used as follows: + +a. RCU applied to normal data structures. + +b. RCU applied to networking data structures that may be subjected + to remote denial-of-service attacks. + +c. RCU applied to scheduler and interrupt/NMI-handler tasks. + +Again, most uses will be of (a). The (b) and (c) cases are important +for specialized uses, but are relatively uncommon. + + +3.

It also clearly shows the +RCU distinction between updater, namely foo_update_a(), and reclaimer, +namely foo_reclaim(). + +The summary of advice is the same as for the previous section, except +that we are now using call_rcu() rather than synchronize_rcu(): + +o Use call_rcu() -after- removing a data element from an + RCU-protected data structure in order to register a callback + function that will be invoked after the completion of all RCU + read-side critical sections that might be referencing that + data item. + +Again, see checklist.txt for additional rules governing the use of RCU. + + +5. WHAT ARE SOME SIMPLE IMPLEMENTATIONS OF RCU? + +One of the nice things about RCU is that it has extremely simple "toy" +implementations that are a good first step towards understanding the +production-quality implementations in the Linux kernel. This section +presents two such "toy" implementations of RCU, one that is implemented +in terms of familiar locking primitives, and another that more closely +resembles "classic" RCU. Both are way too simple for real-world use, +lacking both functionality and performance. However, they are useful +in getting a feel for how RCU works. See kernel/rcupdate.c for a +production-quality implementation, and see: + + http://www.rdrop.com/users/paulmck/RCU + +for papers describing the Linux kernel RCU implementation. The OLS'01 +and OLS'02 papers are a good introduction, and the dissertation provides +more details on the current implementation. + + +5A. "TOY" IMPLEMENTATION #1: LOCKING + +This section presents a "toy" RCU implementation that is based on +familiar locking primitives. Its overhead makes it a non-starter for +real-life use, as does its lack of scalability. It is also unsuitable +for realtime use, since it allows scheduling latency to "bleed" from +one read-side critical section to another. + +However, it is probably the easiest implementation to relate to, so is +a good starting point. + +It is extremely simple: + + static DEFINE_RWLOCK(rcu_gp_mutex); + + void rcu_read_lock(void) + { + read_lock(&rcu_gp_mutex); + } + + void rcu_read_unlock(void) + { + read_unlock(&rcu_gp_mutex); + } + + void synchronize_rcu(void) + { + write_lock(&rcu_gp_mutex); + write_unlock(&rcu_gp_mutex); + } + +[You can ignore rcu_assign_pointer() and rcu_dereference() without +missing much. But here they are anyway. And whatever you do, don't +forget about them when submitting patches making use of RCU!] + + #define rcu_assign_pointer(p, v) ({ \ + smp_wmb(); \ + (p) = (v); \ + }) + + #define rcu_dereference(p) ({ \ + typeof(p) _________p1 = p; \ + smp_read_barrier_depends(); \ + (_________p1); \ + }) + + +The rcu_read_lock() and rcu_read_unlock() primitive read-acquire +and release a global reader-writer lock. The synchronize_rcu() +primitive write-acquires this same lock, then immediately releases +it. This means that once synchronize_rcu() exits, all RCU read-side +critical sections that were in progress before synchonize_rcu() was +called are guaranteed to have completed -- there is no way that +synchronize_rcu() would have been able to write-acquire the lock +otherwise. + +It is possible to nest rcu_read_lock(), since reader-writer locks may +be recursively acquired. Note also that rcu_read_lock() is immune +from deadlock (an important property of RCU). The reason for this is +that the only thing that can block rcu_read_lock() is a synchronize_rcu(). +But synchronize_rcu() does not acquire any locks while holding rcu_gp_mutex, +so there can be no deadlock cycle. + +Quick Quiz #1: Why is this argument naive? How could a deadlock + occur when using this algorithm in a real-world Linux + kernel? How could this deadlock be avoided? + + +5B. "TOY" EXAMPLE #2: CLASSIC RCU + +This section presents a "toy" RCU implementation that is based on +"classic RCU". It is also short on performance (but only for updates) and +on features such as hotplug CPU and the ability to run in CONFIG_PREEMPT +kernels. The definitions of rcu_dereference() and rcu_assign_pointer() +are the same as those shown in the preceding section, so they are omitted. + + void rcu_read_lock(void) { } + + void rcu_read_unlock(void) { } + + void synchronize_rcu(void) + { + int cpu; + + for_each_cpu(cpu) + run_on(cpu); + } + +Note that rcu_read_lock() and rcu_read_unlock() do absolutely nothing. +This is the great strength of classic RCU in a non-preemptive kernel: +read-side overhead is precisely zero, at least on non-Alpha CPUs. +And there is absolutely no way that rcu_read_lock() can possibly +participate in a deadlock cycle! + +The implementation of synchronize_rcu() simply schedules itself on each +CPU in turn. The run_on() primitive can be implemented straightforwardly +in terms of the sched_setaffinity() primitive. Of course, a somewhat less +"toy" implementation would restore the affinity upon completion rather +than just leaving all tasks running on the last CPU, but when I said +"toy", I meant -toy-! + +So how the heck is this supposed to work??? + +Remember that it is illegal to block while in an RCU read-side critical +section. Therefore, if a given CPU executes a context switch, we know +that it must have completed all preceding RCU read-side critical sections. +Once -all- CPUs have executed a context switch, then -all- preceding +RCU read-side critical sections will have completed. + +So, suppose that we remove a data item from its structure and then invoke +synchronize_rcu(). Once synchronize_rcu() returns, we are guaranteed +that there are no RCU read-side critical sections holding a reference +to that data item, so we can safely reclaim it. + +Quick Quiz #2: Give an example where Classic RCU's read-side + overhead is -negative-. + +Quick Quiz #3: If it is illegal to block in an RCU read-side + critical section, what the heck do you do in + PREEMPT_RT, where normal spinlocks can block??? + + +6.

ANSWERS TO QUICK QUIZZES + +Quick Quiz #1: Why is this argument naive? How could a deadlock + occur when using this algorithm in a real-world Linux + kernel? [Referring to the lock-based "toy" RCU + algorithm.] + +Answer: Consider the following sequence of events: + + 1. CPU 0 acquires some unrelated lock, call it + "problematic_lock". + + 2. CPU 1 enters synchronize_rcu(), write-acquiring + rcu_gp_mutex. + + 3. CPU 0 enters rcu_read_lock(), but must wait + because CPU 1 holds rcu_gp_mutex. + + 4. CPU 1 is interrupted, and the irq handler + attempts to acquire problematic_lock. + + The system is now deadlocked. + + One way to avoid this deadlock is to use an approach like + that of CONFIG_PREEMPT_RT, where all normal spinlocks + become blocking locks, and all irq handlers execute in + the context of special tasks. In this case, in step 4 + above, the irq handler would block, allowing CPU 1 to + release rcu_gp_mutex, avoiding the deadlock. + + Even in the absence of deadlock, this RCU implementation + allows latency to "bleed" from readers to other + readers through synchronize_rcu(). To see this, + consider task A in an RCU read-side critical section + (thus read-holding rcu_gp_mutex), task B blocked + attempting to write-acquire rcu_gp_mutex, and + task C blocked in rcu_read_lock() attempting to + read_acquire rcu_gp_mutex. Task A's RCU read-side + latency is holding up task C, albeit indirectly via + task B. + + Realtime RCU implementations therefore use a counter-based + approach where tasks in RCU read-side critical sections + cannot be blocked by tasks executing synchronize_rcu(). + +Quick Quiz #2: Give an example where Classic RCU's read-side + overhead is -negative-. + +Answer: Imagine a single-CPU system with a non-CONFIG_PREEMPT + kernel where a routing table is used by process-context + code, but can be updated by irq-context code (for example, + by an "ICMP REDIRECT" packet). The usual way of handling + this would be to have the process-context code disable + interrupts while searching the routing table. Use of + RCU allows such interrupt-disabling to be dispensed with. + Thus, without RCU, you pay the cost of disabling interrupts, + and with RCU you don't. + + One can argue that the overhead of RCU in this + case is negative with respect to the single-CPU + interrupt-disabling approach. Others might argue that + the overhead of RCU is merely zero, and that replacing + the positive overhead of the interrupt-disabling scheme + with the zero-overhead RCU scheme does not constitute + negative overhead. + + In real life, of course, things are more complex. But + even the theoretical possibility of negative overhead for + a synchronization primitive is a bit unexpected. ;-) + +Quick Quiz #3: If it is illegal to block in an RCU read-side + critical section, what the heck do you do in + PREEMPT_RT, where normal spinlocks can block??? + +Answer: Just as PREEMPT_RT permits preemption of spinlock + critical sections, it permits preemption of RCU + read-side critical sections. It also permits + spinlocks blocking while in RCU read-side critical + sections. + + Why the apparent inconsistency? Because it is it + possible to use priority boosting to keep the RCU + grace periods short if need be (for example, if running + short of memory). In contrast, if blocking waiting + for (say) network reception, there is no way to know + what should be boosted. Especially given that the + process we need to boost might well be a human being + who just went out for a pizza or something.

Hopefully this document +will explain this to you. + +In addition to explaining how to apply and revert patches, a brief +description of the different kernel trees (and examples of how to apply +their specific patches) is also provided. + + +What is a patch? +--- + A patch is a small text document containing a delta of changes between two +different versions of a source tree. Patches are created with the `diff' +program. +To correctly apply a patch you need to know what base it was generated from +and what new version the patch will change the source tree into. These +should both be present in the patch file metadata or be possible to deduce +from the filename. + + +How do I apply or revert a patch? +--- + You apply a patch with the `patch' program. The patch program reads a diff +(or patch) file and makes the changes to the source tree described in it. + +Patches for the Linux kernel are generated relative to the parent directory +holding the kernel source dir. + +This means that paths to files inside the patch file contain the name of the +kernel source directories it was generated against (or some other directory +names like "a/" and "b/"). +Since this is unlikely to match the name of the kernel source dir on your +local machine (but is often useful info to see what version an otherwise +unlabeled patch was generated against) you should change into your kernel +source directory and then strip the first element of the path from filenames +in the patch file when applying it (the -p1 argument to `patch' does this). + +To revert a previously applied patch, use the -R argument to patch. +So, if you applied a patch like this: + patch -p1 < ../patch-x.y.z + +You can revert (undo) it like this: + patch -R -p1 < ../patch-x.y.z + + +How do I feed a patch/diff file to `patch'? +--- + This (as usual with Linux and other UNIX like operating systems) can be +done in several different ways. +In all the examples below I feed the file (in uncompressed form) to patch +via stdin using the following syntax: + patch -p1 < path/to/patch-x.y.z + +If you just want to be able to follow the examples below and don't want to +know of more than one way to use patch, then you can stop reading this +section here. + +Patch can also get the name of the file to use via the -i argument, like +this: + patch -p1 -i path/to/patch-x.y.z + +If your patch file is compressed with gzip or bzip2 and you don't want to +uncompress it before applying it, then you can feed it to patch like this +instead: + zcat path/to/patch-x.y.z.gz | patch -p1 + bzcat path/to/patch-x.y.z.bz2 | patch -p1 + +If you wish to uncompress the patch file by hand first before applying it +(what I assume you've done in the examples below), then you simply run +gunzip or bunzip2 on the file - like this: + gunzip patch-x.y.z.gz + bunzip2 patch-x.y.z.bz2 + +Which will leave you with a plain text patch-x.y.z file that you can feed to +patch via stdin or the -i argument, as you prefer. + +A few other nice arguments for patch are -s which causes patch to be silent +except for errors which is nice to prevent errors from scrolling out of the +screen too fast, and --dry-run which causes patch to just print a listing of +what would happen, but doesn't actually make any changes. Finally --verbose +tells patch to print more information about the work being done. + + +Common errors when patching +--- + When patch applies a patch file it attempts to verify the sanity of the +file in different ways. +Checking that the file looks like a valid patch file, checking the code +around the bits being modified matches the context provided in the patch are +just two of the basic sanity checks patch does. + +If patch encounters something that doesn't look quite right it has two +options. It can either refuse to apply the changes and abort or it can try +to find a way to make the patch apply with a few minor changes. + +One example of something that's not 'quite right' that patch will attempt to +fix up is if all the context matches, the lines being changed match, but the +line numbers are different. This can happen, for example, if the patch makes +a change in the middle of the file but for some reasons a few lines have +been added or removed near the beginning of the file. In that case +everything looks good it has just moved up or down a bit, and patch will +usually adjust the line numbers and apply the patch. + +Whenever patch applies a patch that it had to modify a bit to make it fit +it'll tell you about it by saying the patch applied with 'fuzz'. +You should be wary of such changes since even though patch probably got it +right it doesn't /always/ get it right, and the result will sometimes be +wrong. + +When patch encounters a change that it can't fix up with fuzz it rejects it +outright and leaves a file with a .rej extension (a reject file). You can +read this file to see exactely what change couldn't be applied, so you can +go fix it up by hand if you wish. + +If you don't have any third party patches applied to your kernel source, but +only patches from kernel.org and you apply the patches in the correct order, +and have made no modifications yourself to the source files, then you should +never see a fuzz or reject message from patch. If you do see such messages +anyway, then there's a high risk that either your local source tree or the +patch file is corrupted in some way. In that case you should probably try +redownloading the patch and if things are still not OK then you'd be advised +to start with a fresh tree downloaded in full from kernel.org. + +Let's look a bit more at some of the messages patch can produce. + +If patch stops and presents a "File to patch:" prompt, then patch could not +find a file to be patched. Most likely you forgot to specify -p1 or you are +in the wrong directory. Less often, you'll find patches that need to be +applied with -p0 instead of -p1 (reading the patch file should reveal if +this is the case - if so, then this is an error by the person who created +the patch but is not fatal). + +If you get "Hunk #2 succeeded at 1887 with fuzz 2 (offset 7 lines)." or a +message similar to that, then it means that patch had to adjust the location +of the change (in this example it needed to move 7 lines from where it +expected to make the change to make it fit). +The resulting file may or may not be OK, depending on the reason the file +was different than expected. +This often happens if you try to apply a patch that was generated against a +different kernel version than the one you are trying to patch. + +If you get a message like "Hunk #3 FAILED at 2387.", then it means that the +patch could not be applied correctly and the patch program was unable to +fuzz its way through. This will generate a .rej file with the change that +caused the patch to fail and also a .orig file showing you the original +content that couldn't be changed. + +If you get "Reversed (or previously applied) patch detected! Assume -R? [n]" +then patch detected that the change contained in the patch seems to have +already been made. +If you actually did apply this patch previously and you just re-applied it +in error, then just say [n]o and abort this patch. If you applied this patch +previously and actually intended to revert it, but forgot to specify -R, +then you can say [y]es here to make patch revert it for you. +This can also happen if the creator of the patch reversed the source and +destination directories when creating the patch, and in that case reverting +the patch will in fact apply it. + +A message similar to "patch: **** unexpected end of file in patch" or "patch +unexpectedly ends in middle of line" means that patch could make no sense of +the file you fed to it. Either your download is broken or you tried to feed +patch a compressed patch file without uncompressing it first. + +As I already mentioned above, these errors should never happen if you apply +a patch from kernel.org to the correct version of an unmodified source tree. +So if you get these errors with kernel.org patches then you should probably +assume that either your patch file or your tree is broken and I'd advice you +to start over with a fresh download of a full kernel tree and the patch you +wish to apply. + + +Are there any alternatives to `patch'? +--- + Yes there are alternatives. You can use the `interdiff' program +(http://cyberelk.net/tim/patchutils/) to generate a patch representing the +differences between two patches and then apply the result. +This will let you move from something like 2.6.12.2 to 2.6.12.3 in a single +step. The -z flag to interdiff will even let you feed it patches in gzip or +bzip2 compressed form directly without the use of zcat or bzcat or manual +decompression. + +Here's how you'd go from 2.6.12.2 to 2.6.12.3 in a single step: + interdiff -z ../patch-2.6.12.2.bz2 ../patch-2.6.12.3.gz | patch -p1 + +Although interdiff may save you a step or two you are generally advised to +do the additional steps since interdiff can get things wrong in some cases. + + Another alternative is `ketchup', which is a python script for automatic +downloading and applying of patches (http://www.selenic.com/ketchup/). + +Other nice tools are diffstat which shows a summary of changes made by a +patch, lsdiff which displays a short listing of affected files in a patch +file, along with (optionally) the line numbers of the start of each patch +and grepdiff which displays a list of the files modified by a patch where +the patch contains a given regular expression. + + +Where can I download the patches? +--- + The patches are available at http://kernel.org/ +Most recent patches are linked from the front page, but they also have +specific homes. + +The 2.6.x.y (-stable) and 2.6.x patches live at + ftp://ftp.kernel.org/pub/linux/kernel/v2.6/ + +The -rc patches live at + ftp://ftp.kernel.org/pub/linux/kernel/v2.6/testing/ + +The -git patches live at + ftp://ftp.kernel.org/pub/linux/kernel/v2.6/snapshots/ + +The -mm kernels live at + ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/ + +In place of ftp.kernel.org you can use ftp.cc.kernel.org, where cc is a +country code. This way you'll be downloading from a mirror site that's most +likely geographically closer to you, resulting in faster downloads for you, +less bandwidth used globally and less load on the main kernel.org servers - +these are good things, do use mirrors when possible. + + +The 2.6.x kernels +--- + These are the base stable releases released by Linus. The highest numbered +release is the most recent. + +If regressions or other serious flaws are found then a -stable fix patch +will be released (see below) on top of this base. Once a new 2.6.x base +kernel is released, a patch is made available that is a delta between the +previous 2.6.x kernel and the new one. + +To apply a patch moving from 2.6.11 to 2.6.12 you'd do the following (note +that such patches do *NOT* apply on top of 2.6.x.y kernels but on top of the +base 2.6.x kernel - if you need to move from 2.6.x.y to 2.6.x+1 you need to +first revert the 2.6.x.y patch). + +Here are some examples: + +# moving from 2.6.11 to 2.6.12 +$ cd ~/linux-2.6.11 # change to kernel source dir +$ patch -p1 < ../patch-2.6.12 # apply the 2.6.12 patch +$ cd .. +$ mv linux-2.6.11 linux-2.6.12 # rename source dir + +# moving from 2.6.11.1 to 2.6.12 +$ cd ~/linux-2.6.11.1 # change to kernel source dir +$ patch -p1 -R < ../patch-2.6.11.1 # revert the 2.6.11.1 patch + # source dir is now 2.6.11 +$ patch -p1 < ../patch-2.6.12 # apply new 2.6.12 patch +$ cd .. +$ mv linux-2.6.11.1 inux-2.6.12 # rename source dir + + +The 2.6.x.y kernels +--- + Kernels with 4 digit versions are -stable kernels. They contain small(ish) +critical fixes for security problems or significant regressions discovered +in a given 2.6.x kernel. + +This is the recommended branch for users who want the most recent stable +kernel and are not interested in helping test development/experimental +versions. + +If no 2.6.x.y kernel is available, then the highest numbered 2.6.x kernel is +the current stable kernel. + +These patches are not incremental, meaning that for example the 2.6.12.3 +patch does not apply on top of the 2.6.12.2 kernel source, but rather on top +of the base 2.6.12 kernel source. +So, in order to apply the 2.6.12.3 patch to your existing 2.6.12.2 kernel +source you have to first back out the 2.6.12.2 patch (so you are left with a +base 2.6.12 kernel source) and then apply the new 2.6.12.3 patch. + +Here's a small example: + +$ cd ~/linux-2.6.12.2 # change into the kernel source dir +$ patch -p1 -R < ../patch-2.6.12.2 # revert the 2.6.12.2 patch +$ patch -p1 < ../patch-2.6.12.3 # apply the new 2.6.12.3 patch +$ cd .. +$ mv linux-2.6.12.2 linux-2.6.12.3 # rename the kernel source dir + + +The -rc kernels +--- + These are release-candidate kernels. These are development kernels released +by Linus whenever he deems the current git (the kernel's source management +tool) tree to be in a reasonably sane state adequate for testing. + +These kernels are not stable and you should expect occasional breakage if +you intend to run them. This is however the most stable of the main +development branches and is also what will eventually turn into the next +stable kernel, so it is important that it be tested by as many people as +possible. + +This is a good branch to run for people who want to help out testing +development kernels but do not want to run some of the really experimental +stuff (such people should see the sections about -git and -mm kernels below). + +The -rc patches are not incremental, they apply to a base 2.6.x kernel, just +like the 2.6.x.y patches described above. The kernel version before the -rcN +suffix denotes the version of the kernel that this -rc kernel will eventually +turn into. +So, 2.6.13-rc5 means that this is the fifth release candidate for the 2.6.13 +kernel and the patch should be applied on top of the 2.6.12 kernel source. + +Here are 3 examples of how to apply these patches: + +# first an example of moving from 2.6.12 to 2.6.13-rc3 +$ cd ~/linux-2.6.12 # change into the 2.6.12 source dir +$ patch -p1 < ../patch-2.6.13-rc3 # apply the 2.6.13-rc3 patch +$ cd .. +$ mv linux-2.6.12 linux-2.6.13-rc3 # rename the source dir + +# now let's move from 2.6.13-rc3 to 2.6.13-rc5 +$ cd ~/linux-2.6.13-rc3 # change into the 2.6.13-rc3 dir +$ patch -p1 -R < ../patch-2.6.13-rc3 # revert the 2.6.13-rc3 patch +$ patch -p1 < ../patch-2.6.13-rc5 # apply the new 2.6.13-rc5 patch +$ cd .. +$ mv linux-2.6.13-rc3 linux-2.6.13-rc5 # rename the source dir + +# finally let's try and move from 2.6.12.3 to 2.6.13-rc5 +$ cd ~/linux-2.6.12.3 # change to the kernel source dir +$ patch -p1 -R < ../patch-2.6.12.3 # revert the 2.6.12.3 patch +$ patch -p1 < ../patch-2.6.13-rc5 # apply new 2.6.13-rc5 patch +$ cd .. +$ mv linux-2.6.12.3 linux-2.6.13-rc5 # rename the kernel source dir + + +The -git kernels +--- + These are daily snapshots of Linus' kernel tree (managed in a git +repository, hence the name). + +These patches are usually released daily and represent the current state of +Linus' tree.

It is developed and +tested using a VIA EPIA 5000 board. + +Cyblafb - compiled into the kernel or as a module? +================================================== + +You might compile cyblafb either as a module or compile it permanently into the +kernel. + +Unless you have a real reason to do so you should not compile both vesafb and +cyblafb permanently into the kernel. It's possible and it helps during the +developement cycle, but it's useless and will at least block some otherwise +usefull memory for ordinary users. + +Selecting Modes +=============== + + Startup Mode + ============ + + First of all, you might use the "vga=???" boot parameter as it is + documented in vesafb.txt and svga.txt. Cyblafb will detect the video + mode selected and will use the geometry and timings found by + inspecting the hardware registers. + + video=cyblafb vga=0x317 + + Alternatively you might use a combination of the mode, ref and bpp + parameters. If you compiled the driver into the kernel, add something + like this to the kernel command line: + + video=cyblafb:1280x1024,bpp=16,ref=50 ... + + If you compiled the driver as a module, the same mode would be + selected by the following command: + + modprobe cyblafb mode=1280x1024 bpp=16 ref=50 ... + + None of the modes possible to select as startup modes are affected by + the problems described at the end of the next subsection. + + Mode changes using fbset + ======================== + + You might use fbset to change the video mode, see "man fbset". Cyblafb + generally does assume that you know what you are doing. But it does + some checks, especially those that are needed to prevent you from + damaging your hardware. + + - only 8, 16, 24 and 32 bpp video modes are accepted + - interlaced video modes are not accepted + - double scan video modes are not accepted + - if a flat panel is found, cyblafb does not allow you + to program a resolution higher than the physical + resolution of the flat panel monitor + - cyblafb does not allow xres to differ from xres_virtual + - cyblafb does not allow vclk to exceed 230 MHz. As 32 bpp + and (currently) 24 bit modes use a doubled vclk internally, + the dotclock limit as seen by fbset is 115 MHz for those + modes and 230 MHz for 8 and 16 bpp modes. + + Any request that violates the rules given above will be ignored and + fbset will return an error. + + If you program a virtual y resolution higher than the hardware limit, + cyblafb will silently decrease that value to the highest possible + value. + + Attempts to disable acceleration are ignored. + + Some video modes that should work do not work as expected. If you use + the standard fb.modes, fbset 640x480-60 will program that mode, but + you will see a vertical area, about two characters wide, with only + much darker characters than the other characters on the screen. + Cyblafb does allow that mode to be set, as it does not violate the + official specifications. It would need a lot of code to reliably sort + out all invalid modes, playing around with the margin values will + give a valid mode quickly. And if cyblafb would detect such an invalid + mode, should it silently alter the requested values or should it + report an error? Both options have some pros and cons. As stated + above, none of the startup modes are affected, and if you set + verbosity to 1 or higher, cyblafb will print the fbset command that + would be needed to program that mode using fbset. + + +Other Parameters +================ + + +crt don't autodetect, assume monitor connected to + standard VGA connector + +fp don't autodetect, assume flat panel display + connected to flat panel monitor interface + +nativex inform driver about native x resolution of + flat panel monitor connected to special + interface (should be autodetected) + +stretch stretch image to adapt low resolution modes to + higer resolutions of flat panel monitors + connected to special interface + +center center image to adapt low resolution modes to + higer resolutions of flat panel monitors + connected to special interface + +memsize use if autodetected memsize is wrong ... + should never be necessary + +nopcirr disable PCI read retry +nopciwr disable PCI write retry +nopcirb disable PCI read bursts +nopciwb disable PCI write bursts + +bpp bpp for specified modes + valid values: 8 || 16 || 24 || 32 + +ref refresh rate for specified mode + valid values: 50 <= ref <= 85 + +mode 640x480 or 800x600 or 1024x768 or 1280x1024 + if not specified, the startup mode will be detected + and used, so you might also use the vga=??? parameter + described in vesafb.txt.

See sections "Module unloading ...". + + +Development hints +================= + +It's much faster do compile a module and to load the new version after +unloading the old module than to compile a new kernel and to reboot. So if you +try to work on cyblafb, it might be a good idea to use cyblafb as a module. +In real life, fast often means dangerous, and that's also the case here. If +you introduce a serious bug when cyblafb is compiled into the kernel, the +kernel will lock or oops with a high probability before the file system is +mounted, and the danger for your data is low. If you load a broken own version +of cyblafb on a running system, the danger for the integrity of the file +system is much higher as you might need a hard reset afterwards. Decide +yourself. + +Module unloading, the vfb method +================================ + +If you want to unload/reload cyblafb using the virtual framebuffer, you need +to enable vfb support in the kernel first. After that, load the modules as +shown below: + + modprobe vfb vfb_enable=1 + modprobe fbcon + modprobe cyblafb + fbset -fb /dev/fb1 1280x1024-60 -vyres 2662 + con2fb /dev/fb1 /dev/tty1 + ... + +If you now made some changes to cyblafb and want to reload it, you might do it +as show below: + + con2fb /dev/fb0 /dev/tty1 + ... + rmmod cyblafb + modprobe cyblafb + con2fb /dev/fb1 /dev/tty1 + ... + +Of course, you might choose another mode, and most certainly you also want to +map some other /dev/tty* to the real framebuffer device.

The +first was the Discrete Video Timings (DVT) which is a collection of +pre-defined modes approved by VESA(TM).

Typically +this would be the case for posix threads. As with the common +refcounting model in the kernel, the last task doing +a put_files_struct() frees the file descriptor (fd) table. +The files (struct file) themselves are protected using +reference count (->f_count). + +In the new lock-free model of file descriptor management, +the reference counting is similar, but the locking is +based on RCU. The file descriptor table contains multiple +elements - the fd sets (open_fds and close_on_exec, the +array of file pointers, the sizes of the sets and the array +etc.). In order for the updates to appear atomic to +a lock-free reader, all the elements of the file descriptor +table are in a separate structure - struct fdtable. +files_struct contains a pointer to struct fdtable through +which the actual fd table is accessed. Initially the +fdtable is embedded in files_struct itself. On a subsequent +expansion of fdtable, a new fdtable structure is allocated +and files->fdtab points to the new structure. The fdtable +structure is freed with RCU and lock-free readers either +see the old fdtable or the new fdtable making the update +appear atomic. Here are the locking rules for +the fdtable structure - + +1. All references to the fdtable must be done through + the files_fdtable() macro : + + struct fdtable *fdt; + + rcu_read_lock(); + + fdt = files_fdtable(files); + .... + if (n <= fdt->max_fds) + .... + ... + rcu_read_unlock(); + + files_fdtable() uses rcu_dereference() macro which takes care of + the memory barrier requirements for lock-free dereference. + The fdtable pointer must be read within the read-side + critical section. + +2. Reading of the fdtable as described above must be protected + by rcu_read_lock()/rcu_read_unlock(). + +3. For any update to the the fd table, files->file_lock must + be held. + +4. To look up the file structure given an fd, a reader + must use either fcheck() or fcheck_files() APIs. These + take care of barrier requirements due to lock-free lookup. + An example : + + struct file *file; + + rcu_read_lock(); + file = fcheck(fd); + if (file) { + ... + } + .... + rcu_read_unlock(); + +5. Handling of the file structures is special. Since the look-up + of the fd (fget()/fget_light()) are lock-free, it is possible + that look-up may race with the last put() operation on the + file structure. This is avoided using the rcuref APIs + on ->f_count : + + rcu_read_lock(); + file = fcheck_files(files, fd); + if (file) { + if (rcuref_inc_lf(&file->f_count)) + *fput_needed = 1; + else + /* Didn't get the reference, someone's freed */ + file = NULL; + } + rcu_read_unlock(); + .... + return file; + + rcuref_inc_lf() detects if refcounts is already zero or + goes to zero during increment. If it does, we fail + fget()/fget_light(). + +6. Since both fdtable and file structures can be looked up + lock-free, they must be installed using rcu_assign_pointer() + API. If they are looked up lock-free, rcu_dereference() + must be used. However it is advisable to use files_fdtable() + and fcheck()/fcheck_files() which take care of these issues. + +7.

Obvious requirements arising from this are: + + A) mount owner should not be able to get elevated privileges with the + help of the mounted filesystem + + B) mount owner should not get illegitimate access to information from + other users' and the super user's processes + + C) mount owner should not be able to induce undesired behavior in + other users' or the super user's processes + +How are requirements fulfilled? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + A) The mount owner could gain elevated privileges by either: + + 1) creating a filesystem containing a device file, then opening + this device + + 2) creating a filesystem containing a suid or sgid application, + then executing this application + + The solution is not to allow opening device files and ignore + setuid and setgid bits when executing programs. To ensure this + fusermount always adds "nosuid" and "nodev" to the mount options + for non-privileged mounts. + + B) If another user is accessing files or directories in the + filesystem, the filesystem daemon serving requests can record the + exact sequence and timing of operations performed. This + information is otherwise inaccessible to the mount owner, so this + counts as an information leak. + + The solution to this problem will be presented in point 2) of C). + + C) There are several ways in which the mount owner can induce + undesired behavior in other users' processes, such as: + + 1) mounting a filesystem over a file or directory which the mount + owner could otherwise not be able to modify (or could only + make limited modifications). + + This is solved in fusermount, by checking the access + permissions on the mountpoint and only allowing the mount if + the mount owner can do unlimited modification (has write + access to the mountpoint, and mountpoint is not a "sticky" + directory) + + 2) Even if 1) is solved the mount owner can change the behavior + of other users' processes. + + i) It can slow down or indefinitely delay the execution of a + filesystem operation creating a DoS against the user or the + whole system. For example a suid application locking a + system file, and then accessing a file on the mount owner's + filesystem could be stopped, and thus causing the system + file to be locked forever. + + ii) It can present files or directories of unlimited length, or + directory structures of unlimited depth, possibly causing a + system process to eat up diskspace, memory or other + resources, again causing DoS. + + The solution to this as well as B) is not to allow processes + to access the filesystem, which could otherwise not be + monitored or manipulated by the mount owner. Since if the + mount owner can ptrace a process, it can do all of the above + without using a FUSE mount, the same criteria as used in + ptrace can be used to check if a process is allowed to access + the filesystem or not. + + Note that the ptrace check is not strictly necessary to + prevent B/2/i, it is enough to check if mount owner has enough + privilege to send signal to the process accessing the + filesystem, since SIGSTOP can be used to get a similar effect. + +I think these limitations are unacceptable? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If a sysadmin trusts the users enough, or can ensure through other +measures, that system processes will never enter non-privileged +mounts, it can relax the last limitation with a "user_allow_other" +config option.

EH's goals are two - make LLDD, host and +device forget about timed out scmds and make them ready for new +commands. A scmd is said to be recovered if the scmd is forgotten by +lower layers and lower layers are ready to process or fail the scmd +again. + + To achieve these goals, EH performs recovery actions with increasing +severity. Some actions are performed by issueing SCSI commands and +others are performed by invoking one of the following fine-grained +hostt EH callbacks.
