* Command for inspecting coreboot tables (`lscoreboot').
* New target default_payload.elf.
* Increased maximal core size.
* Prefer pmtimer for TSC calibration.
* New/improved platform support:
* New `efifwsetup' and `lsefi' commands on EFI platforms.
@ -88,6 +89,13 @@ New in 2.02:
* Support *-emu on Windows.
* New platform `none' which builds only user level utilities. This is now
default if target CPU is not supported.
* Support for booting little-endian Linux kernel on powerpc.
* Support network boot with Oracle sun4v vnet devices.
* Added SAS disks to the IEEE 1275 Open Firmware device list.
* Try multiple methods for TSC (timestamp counter) calibration - PIT, pmtimer,
EFI Stall. If everything fails, use hardcoded frequency 800MHz.
* Support Hyper-V Gen2 platforms which lack PIT for TSC calibration.
* Map UEFI Persistent Memory to E820 persistent memory.
* Security:
* Add optional facility to enforce that all files read by the core image

directly. This removes requirement for target-specific runtime on build
system.
* emu libusb support removed (was broken and unmaintained).
* powerpc64le compile support.
* Use fixed timestamp when generating GRUB image for reproducible builds.
* Revision control moved to git.

More extensive documentation is available in the Info manual,
accessible using 'info grub' after building and installing GRUB 2.
Please look at the GRUB Wiki <http://grub.enbug.org> for testing
procedures.
There are a number of important user-visible differences from the
first version of GRUB, now known as GRUB Legacy. For a summary, please

limitations mips-loongson (with Linux protocol)
and mips-qemu_mips can use only memory up to first hole.
Bootlocation is ability of GRUB to automatically detect where it boots from.
``disk'' means the detection is limited to detecting the disk with partition
being discovered on install time. ``partition'' means that disk and partiton
can be automatically discovered. ``file'' means that boot image file name as
well as disk and partition can be discovered. For consistency default install ignores
partition and relies solely on disk detection. If no bootlocation discovery is available
or boot and grub-root disks are different, UUID is used instead. On ARC if no device
to install to is specified, UUID is used instead as well.

* `incontents 150 evtchn Event Channels
*
* Event channels are the basic primitive provided by Xen for event
* notifications. An event is the Xen equivalent of a hardware
* interrupt. They essentially store one bit of information, the event
* of interest is signalled by transitioning this bit from 0 to 1.
*
* Notifications are received by a guest via an upcall from Xen,
* indicating when an event arrives (setting the bit). Further
* notifications are masked until the bit is cleared again (therefore,
* guests must check the value of the bit after re-enabling event
* delivery to ensure no missed notifications).
*
* Event notifications can be masked by setting a flag; this is
* equivalent to disabling interrupts and can be used to ensure
* atomicity of certain operations in the guest kernel.
*
* Event channels are represented by the evtchn_* fields in
* struct shared_info and struct vcpu_info.

* `incontents 150 gnttab Grant Tables
*
* Xen's grant tables provide a generic mechanism to memory sharing
* between domains. This shared memory interface underpins the split
* device drivers for block and network IO.
*
* Each domain has its own grant table. This is a data structure that
* is shared with Xen; it allows the domain to tell Xen what kind of
* permissions other domains have on its pages. Entries in the grant
* table are identified by grant references. A grant reference is an
* integer, which indexes into the grant table. It acts as a
* capability which the grantee can use to perform operations on the
* granter’s memory.
*
* This capability-based system allows shared-memory communications
* between unprivileged domains. A grant reference also encapsulates
* the details of a shared page, removing the need for a domain to
* know the real machine address of a page it is sharing. This makes
* it possible to share memory correctly with domains running in
* fully virtualised memory.

* http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob;f=drivers/xen/grant-table.c;hb=HEAD
*
* NB. WMB is a no-op on current-generation x86 processors. However, a
* compiler barrier will still be required.
*
* Introducing a valid entry into the grant table:
* 1. Write ent->domid.
* 2. Write ent->frame:
* GTF_permit_access: Frame to which access is permitted.
* GTF_accept_transfer: Pseudo-phys frame slot being filled by new
* frame, or zero if none.
* 3. Write memory barrier (WMB).
* 4. Write ent->flags, inc. valid type.
*
* Invalidating an unused GTF_permit_access entry:
* 1. flags = ent->flags.
* 2. Observe that !(flags & (GTF_reading|GTF_writing)).
* 3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
* NB. No need for WMB as reuse of entry is control-dependent on success of
* step 3, and all architectures guarantee ordering of ctrl-dep writes.
*
* Invalidating an in-use GTF_permit_access entry:
* This cannot be done directly. Request assistance from the domain controller
* which can set a timeout on the use of a grant entry and take necessary
* action. (NB. This is not yet implemented!).
*
* Invalidating an unused GTF_accept_transfer entry:
* 1. flags = ent->flags.
* 2. Observe that !(flags & GTF_transfer_committed). [*]
* 3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
* NB. No need for WMB as reuse of entry is control-dependent on success of
* step 3, and all architectures guarantee ordering of ctrl-dep writes.
* [*] If GTF_transfer_committed is set then the grant entry is 'committed'.
* The guest must /not/ modify the grant entry until the address of the
* transferred frame is written. It is safe for the guest to spin waiting
* for this to occur (detect by observing GTF_transfer_completed in
* ent->flags).
*
* Invalidating a committed GTF_accept_transfer entry:
* 1. Wait for (ent->flags & GTF_transfer_completed).
*
* Changing a GTF_permit_access from writable to read-only:
* Use SMP-safe CMPXCHG to set GTF_readonly, while checking !GTF_writing.

* Changing a GTF_permit_access from read-only to writable:

* Feature and Parameter Negotiation
* =================================
* The two halves of a Xen block driver utilize nodes within the XenStore to
* communicate capabilities and to negotiate operating parameters. This
* section enumerates these nodes which reside in the respective front and
* backend portions of the XenStore, following the XenBus convention.
*
* All data in the XenStore is stored as strings. Nodes specifying numeric
* values are encoded in decimal. Integer value ranges listed below are
* expressed as fixed sized integer types capable of storing the conversion
* of a properly formated node string, without loss of information.
*
* Any specified default value is in effect if the corresponding XenBus node
* is not present in the XenStore.
*
* XenStore nodes in sections marked "PRIVATE" are solely for use by the
* driver side whose XenBus tree contains them.
*
* XenStore nodes marked "DEPRECATED" in their notes section should only be
* used to provide interoperability with legacy implementations.
*
* See the XenBus state transition diagram below for details on when XenBus
* nodes must be published and when they can be queried.
*
*****************************************************************************
* Backend XenBus Nodes
*****************************************************************************
*
*------------------ Backend Device Identification (PRIVATE) ------------------
*
* mode
* Values: "r" (read only), "w" (writable)
*
* The read or write access permissions to the backing store to be
* granted to the frontend.
*
* params
* Values: string
*
* A free formatted string providing sufficient information for the
* backend driver to open the backing device. (e.g. the path to the
* file or block device representing the backing store.)
*
* type
* Values: "file", "phy", "tap"
*
* The type of the backing device/object.
*
*--------------------------------- Features ---------------------------------
*
* feature-barrier
* Values: 0/1 (boolean)
* Default Value: 0
*
* A value of "1" indicates that the backend can process requests
* containing the BLKIF_OP_WRITE_BARRIER request opcode. Requests
* of this type may still be returned at any time with the
* BLKIF_RSP_EOPNOTSUPP result code.
*
* feature-flush-cache
* Values: 0/1 (boolean)
* Default Value: 0
*
* A value of "1" indicates that the backend can process requests
* containing the BLKIF_OP_FLUSH_DISKCACHE request opcode. Requests
* of this type may still be returned at any time with the
* BLKIF_RSP_EOPNOTSUPP result code.
*
* feature-discard
* Values: 0/1 (boolean)
* Default Value: 0
*
* A value of "1" indicates that the backend can process requests
* containing the BLKIF_OP_DISCARD request opcode. Requests
* of this type may still be returned at any time with the
* BLKIF_RSP_EOPNOTSUPP result code.
*
* feature-persistent
* Values: 0/1 (boolean)
* Default Value: 0
* Notes: 7
*
* A value of "1" indicates that the backend can keep the grants used
* by the frontend driver mapped, so the same set of grants should be
* used in all transactions. The maximum number of grants the backend
* can map persistently depends on the implementation, but ideally it
* should be RING_SIZE * BLKIF_MAX_SEGMENTS_PER_REQUEST. Using this
* feature the backend doesn't need to unmap each grant, preventing
* costly TLB flushes. The backend driver should only map grants
* persistently if the frontend supports it. If a backend driver chooses
* to use the persistent protocol when the frontend doesn't support it,
* it will probably hit the maximum number of persistently mapped grants
* (due to the fact that the frontend won't be reusing the same grants),
* and fall back to non-persistent mode. Backend implementations may
* shrink or expand the number of persistently mapped grants without
* notifying the frontend depending on memory constraints (this might
* cause a performance degradation).
*
* If a backend driver wants to limit the maximum number of persistently
* mapped grants to a value less than RING_SIZE *
* BLKIF_MAX_SEGMENTS_PER_REQUEST a LRU strategy should be used to
* discard the grants that are less commonly used. Using a LRU in the
* backend driver paired with a LIFO queue in the frontend will
* allow us to have better performance in this scenario.
*
*----------------------- Request Transport Parameters ------------------------
*
* max-ring-page-order
* Values: <uint32_t>
* Default Value: 0
* Notes: 1, 3
*
* The maximum supported size of the request ring buffer in units of
* lb(machine pages). (e.g. 0 == 1 page, 1 = 2 pages, 2 == 4 pages,
* etc.).
*
* max-ring-pages
* Values: <uint32_t>
* Default Value: 1
* Notes: DEPRECATED, 2, 3
*
* The maximum supported size of the request ring buffer in units of
* machine pages. The value must be a power of 2.
*
*------------------------- Backend Device Properties -------------------------
*
* discard-alignment
* Values: <uint32_t>
* Default Value: 0
* Notes: 4, 5
*
* The offset, in bytes from the beginning of the virtual block device,
* to the first, addressable, discard extent on the underlying device.
*
* discard-granularity
* Values: <uint32_t>
* Default Value: <"sector-size">
* Notes: 4
*
* The size, in bytes, of the individually addressable discard extents
* of the underlying device.
*
* discard-secure
* Values: 0/1 (boolean)
* Default Value: 0
* Notes: 10
*
* A value of "1" indicates that the backend can process BLKIF_OP_DISCARD
* requests with the BLKIF_DISCARD_SECURE flag set.
*
* info
* Values: <uint32_t> (bitmap)
*
* A collection of bit flags describing attributes of the backing
* device. The VDISK_* macros define the meaning of each bit
* location.
*
* sector-size
* Values: <uint32_t>
*
* The logical sector size, in bytes, of the backend device.
*
* physical-sector-size
* Values: <uint32_t>
*
* The physical sector size, in bytes, of the backend device.
*
* sectors
* Values: <uint64_t>
*
* The size of the backend device, expressed in units of its logical
* sector size ("sector-size").
*
*****************************************************************************
* Frontend XenBus Nodes
*****************************************************************************
*
*----------------------- Request Transport Parameters -----------------------
*
* event-channel
* Values: <uint32_t>
*
* The identifier of the Xen event channel used to signal activity
* in the ring buffer.
*
* ring-ref
* Values: <uint32_t>
* Notes: 6
*
* The Xen grant reference granting permission for the backend to map
* the sole page in a single page sized ring buffer.
*
* ring-ref%u
* Values: <uint32_t>
* Notes: 6
*
* For a frontend providing a multi-page ring, a "number of ring pages"
* sized list of nodes, each containing a Xen grant reference granting
* permission for the backend to map the page of the ring located
* at page index "%u". Page indexes are zero based.
*
* protocol
* Values: string (XEN_IO_PROTO_ABI_*)
* Default Value: XEN_IO_PROTO_ABI_NATIVE
*
* The machine ABI rules governing the format of all ring request and
* response structures.
*
* ring-page-order
* Values: <uint32_t>
* Default Value: 0
* Maximum Value: MAX(ffs(max-ring-pages) - 1, max-ring-page-order)
* Notes: 1, 3
*
* The size of the frontend allocated request ring buffer in units
* of lb(machine pages). (e.g. 0 == 1 page, 1 = 2 pages, 2 == 4 pages,
* etc.).
*
* num-ring-pages
* Values: <uint32_t>
* Default Value: 1
* Maximum Value: MAX(max-ring-pages,(0x1 << max-ring-page-order))
* Notes: DEPRECATED, 2, 3
*
* The size of the frontend allocated request ring buffer in units of
* machine pages. The value must be a power of 2.
*
* feature-persistent
* Values: 0/1 (boolean)
* Default Value: 0
* Notes: 7, 8, 9
*
* A value of "1" indicates that the frontend will reuse the same grants
* for all transactions, allowing the backend to map them with write
* access (even when it should be read-only). If the frontend hits the
* maximum number of allowed persistently mapped grants, it can fallback
* to non persistent mode. This will cause a performance degradation,
* since the the backend driver will still try to map those grants
* persistently. Since the persistent grants protocol is compatible with
* the previous protocol, a frontend driver can choose to work in
* persistent mode even when the backend doesn't support it.
*
* It is recommended that the frontend driver stores the persistently
* mapped grants in a LIFO queue, so a subset of all persistently mapped
* grants gets used commonly. This is done in case the backend driver
* decides to limit the maximum number of persistently mapped grants
* to a value less than RING_SIZE * BLKIF_MAX_SEGMENTS_PER_REQUEST.
*
*------------------------- Virtual Device Properties -------------------------
*
* device-type
* Values: "disk", "cdrom", "floppy", etc.
*
* virtual-device
* Values: <uint32_t>
*
* A value indicating the physical device to virtualize within the
* frontend's domain. (e.g. "The first ATA disk", "The third SCSI
* disk", etc.)
*
* See docs/misc/vbd-interface.txt for details on the format of this
* value.
*
* Notes
* -----
* (1) Multi-page ring buffer scheme first developed in the Citrix XenServer
* PV drivers.
* (2) Multi-page ring buffer scheme first used in some RedHat distributions
* including a distribution deployed on certain nodes of the Amazon
* EC2 cluster.
* (3) Support for multi-page ring buffers was implemented independently,
* in slightly different forms, by both Citrix and RedHat/Amazon.
* For full interoperability, block front and backends should publish
* identical ring parameters, adjusted for unit differences, to the
* XenStore nodes used in both schemes.
* (4) Devices that support discard functionality may internally allocate space
* (discardable extents) in units that are larger than the exported logical
* block size. If the backing device has such discardable extents the
* backend should provide both discard-granularity and discard-alignment.
* Providing just one of the two may be considered an error by the frontend.
* Backends supporting discard should include discard-granularity and
* discard-alignment even if it supports discarding individual sectors.
* Frontends should assume discard-alignment == 0 and discard-granularity
* == sector size if these keys are missing.
* (5) The discard-alignment parameter allows a physical device to be
* partitioned into virtual devices that do not necessarily begin or
* end on a discardable extent boundary.
* (6) When there is only a single page allocated to the request ring,
* 'ring-ref' is used to communicate the grant reference for this
* page to the backend. When using a multi-page ring, the 'ring-ref'
* node is not created. Instead 'ring-ref0' - 'ring-refN' are used.
* (7) When using persistent grants data has to be copied from/to the page
* where the grant is currently mapped. The overhead of doing this copy
* however doesn't suppress the speed improvement of not having to unmap
* the grants.
* (8) The frontend driver has to allow the backend driver to map all grants
* with write access, even when they should be mapped read-only, since
* further requests may reuse these grants and require write permissions.
* (9) Linux implementation doesn't have a limit on the maximum number of
* grants that can be persistently mapped in the frontend driver, but
* due to the frontent driver implementation it should never be bigger
* than RING_SIZE * BLKIF_MAX_SEGMENTS_PER_REQUEST.
*(10) The discard-secure property may be present and will be set to 1 if the
* backing device supports secure discard.

* Drivers that support optional features and/or transport parameter

* @foreigndom[15:0]: FD, the expected owner of data pages referenced in this
* hypercall invocation. Can be DOMID_SELF.
* @foreigndom[31:16]: PFD, the expected owner of pagetable pages referenced

* (x) encodes the PFD as follows:
* x == 0 => PFD == DOMID_SELF
* x != 0 => PFD == x - 1
*
* Sub-commands: ptr[1:0] specifies the appropriate MMU_* command.
* -------------
* ptr[1:0] == MMU_NORMAL_PT_UPDATE:
* Updates an entry in a page table belonging to PFD. If updating an L1 table,
* and the new table entry is valid/present, the mapped frame must belong to
* FD. If attempting to map an I/O page then the caller assumes the privilege
* of the FD.
* FD == DOMID_IO: Permit /only/ I/O mappings, at the priv level of the caller.
* FD == DOMID_XEN: Map restricted areas of Xen's heap space.
* ptr[:2] -- Machine address of the page-table entry to modify.
* val -- Value to write.
*
* There also certain implicit requirements when using this hypercall. The
* pages that make up a pagetable must be mapped read-only in the guest.
* This prevents uncontrolled guest updates to the pagetable. Xen strictly
* enforces this, and will disallow any pagetable update which will end up
* mapping pagetable page RW, and will disallow using any writable page as a
* pagetable. In practice it means that when constructing a page table for a
* process, thread, etc, we MUST be very dilligient in following these rules:
* 1). Start with top-level page (PGD or in Xen language: L4). Fill out
* the entries.
* 2). Keep on going, filling out the upper (PUD or L3), and middle (PMD
* or L2).
* 3). Start filling out the PTE table (L1) with the PTE entries. Once
* done, make sure to set each of those entries to RO (so writeable bit
* is unset). Once that has been completed, set the PMD (L2) for this
* PTE table as RO.
* 4). When completed with all of the PMD (L2) entries, and all of them have
* been set to RO, make sure to set RO the PUD (L3). Do the same
* operation on PGD (L4) pagetable entries that have a PUD (L3) entry.
* 5). Now before you can use those pages (so setting the cr3), you MUST also
* pin them so that the hypervisor can verify the entries. This is done
* via the HYPERVISOR_mmuext_op(MMUEXT_PIN_L4_TABLE, guest physical frame
* number of the PGD (L4)). And this point the HYPERVISOR_mmuext_op(
* MMUEXT_NEW_BASEPTR, guest physical frame number of the PGD (L4)) can be
* issued.
* For 32-bit guests, the L4 is not used (as there is less pagetables), so
* instead use L3.
* At this point the pagetables can be modified using the MMU_NORMAL_PT_UPDATE
* hypercall. Also if so desired the OS can also try to write to the PTE
* and be trapped by the hypervisor (as the PTE entry is RO).
*
* To deallocate the pages, the operations are the reverse of the steps
* mentioned above. The argument is MMUEXT_UNPIN_TABLE for all levels and the
* pagetable MUST not be in use (meaning that the cr3 is not set to it).
*
* ptr[1:0] == MMU_MACHPHYS_UPDATE:
* Updates an entry in the machine->pseudo-physical mapping table.
* ptr[:2] -- Machine address within the frame whose mapping to modify.
* The frame must belong to the FD, if one is specified.
* val -- Value to write into the mapping entry.
*
* ptr[1:0] == MMU_PT_UPDATE_PRESERVE_AD:
* As MMU_NORMAL_PT_UPDATE above, but A/D bits currently in the PTE are ORed
* with those in @val.
*
* @val is usually the machine frame number along with some attributes.
* The attributes by default follow the architecture defined bits. Meaning that
* if this is a X86_64 machine and four page table layout is used, the layout
* of val is:
* - 63 if set means No execute (NX)
* - 46-13 the machine frame number
* - 12 available for guest
* - 11 available for guest
* - 10 available for guest
* - 9 available for guest
* - 8 global
* - 7 PAT (PSE is disabled, must use hypercall to make 4MB or 2MB pages)
* - 6 dirty
* - 5 accessed
* - 4 page cached disabled
* - 3 page write through
* - 2 userspace accessible
* - 1 writeable
* - 0 present
*
* The one bits that does not fit with the default layout is the PAGE_PSE
* also called PAGE_PAT). The MMUEXT_[UN]MARK_SUPER arguments to the
* HYPERVISOR_mmuext_op serve as mechanism to set a pagetable to be 4MB
* (or 2MB) instead of using the PAGE_PSE bit.
*
* The reason that the PAGE_PSE (bit 7) is not being utilized is due to Xen
* using it as the Page Attribute Table (PAT) bit - for details on it please
* refer to Intel SDM 10.12. The PAT allows to set the caching attributes of
* pages instead of using MTRRs.
*
* The PAT MSR is as follows (it is a 64-bit value, each entry is 8 bits):
* PAT4 PAT0
* +-----+-----+----+----+----+-----+----+----+
* | UC | UC- | WC | WB | UC | UC- | WC | WB | <= Linux
* +-----+-----+----+----+----+-----+----+----+
* | UC | UC- | WT | WB | UC | UC- | WT | WB | <= BIOS (default when machine boots)
* +-----+-----+----+----+----+-----+----+----+
* | rsv | rsv | WP | WC | UC | UC- | WT | WB | <= Xen
* +-----+-----+----+----+----+-----+----+----+
*
* The lookup of this index table translates to looking up
* Bit 7, Bit 4, and Bit 3 of val entry:
*
* PAT/PSE (bit 7) ... PCD (bit 4) .. PWT (bit 3).
*
* If all bits are off, then we are using PAT0. If bit 3 turned on,
* then we are using PAT1, if bit 3 and bit 4, then PAT2..
*
* As you can see, the Linux PAT1 translates to PAT4 under Xen. Which means
* that if a guest that follows Linux's PAT setup and would like to set Write
* Combined on pages it MUST use PAT4 entry. Meaning that Bit 7 (PAGE_PAT) is
* set. For example, under Linux it only uses PAT0, PAT1, and PAT2 for the
* caching as:
*
* WB = none (so PAT0)
* WC = PWT (bit 3 on)
* UC = PWT | PCD (bit 3 and 4 are on).
*
* To make it work with Xen, it needs to translate the WC bit as so:
*
* PWT (so bit 3 on) --> PAT (so bit 7 is on) and clear bit 3
*
* And to translate back it would:
*
* PAT (bit 7 on) --> PWT (bit 3 on) and clear bit 7.

* 3. Virtual interrupts ('events'). A domain can bind an event-channel

* 2. MASK -- if this bit is clear then a 0->1 transition of PENDING

* becomes pending while the channel is masked then the 'edge' is lost
* (i.e., when the channel is unmasked, the guest must manually handle
* pending notifications as no upcall will be scheduled by Xen).
*
* To expedite scanning of pending notifications, any 0->1 pending
* transition on an unmasked channel causes a corresponding bit in a
