(1) if the DMA zone does not exist or

(3) if any node's DMA zone comprises greater than 70% of its local memory and
the amount of local memory is big enough.
Specify "[Dd]efault" to request automatic configuration.
Otherwise, "zone" order will be selected. Default order is recommended unless
this is causing problems for your system/application.
On 32-bit, the Normal zone needs to be preserved for allocations accessible
by the kernel, so "zone" order will be selected.
On 64-bit, devices that require DMA32/DMA are relatively rare, so "node"
order will be selected.

Memory Protection Keys for Userspace (PKU aka PKEYs) is a CPU feature
which will be found on future Intel CPUs.
Memory Protection Keys provides a mechanism for enforcing page-based
protections, but without requiring modification of the page tables
when an application changes protection domains. It works by
dedicating 4 previously ignored bits in each page table entry to a
"protection key", giving 16 possible keys.
There is also a new user-accessible register (PKRU) with two separate
bits (Access Disable and Write Disable) for each key. Being a CPU
register, PKRU is inherently thread-local, potentially giving each
thread a different set of protections from every other thread.
There are two new instructions (RDPKRU/WRPKRU) for reading and writing
to the new register. The feature is only available in 64-bit mode,
even though there is theoretically space in the PAE PTEs. These
permissions are enforced on data access only and have no effect on
instruction fetches.
=========================== Config Option ===========================
This config option adds approximately 1.5kb of text. and 50 bytes of
data to the executable. A workload which does large O_DIRECT reads
of holes in XFS files was run to exercise get_user_pages_fast(). No
performance delta was observed with the config option
enabled or disabled.

x86 Topology
============
This documents and clarifies the main aspects of x86 topology modelling and
representation in the kernel. Update/change when doing changes to the
respective code.
The architecture-agnostic topology definitions are in
Documentation/cputopology.txt. This file holds x86-specific
differences/specialities which must not necessarily apply to the generic
definitions. Thus, the way to read up on Linux topology on x86 is to start
with the generic one and look at this one in parallel for the x86 specifics.
Needless to say, code should use the generic functions - this file is *only*
here to *document* the inner workings of x86 topology.
Started by Thomas Gleixner <tglx@linutronix.de> and Borislav Petkov <bp@alien8.de>.
The main aim of the topology facilities is to present adequate interfaces to
code which needs to know/query/use the structure of the running system wrt
threads, cores, packages, etc.
The kernel does not care about the concept of physical sockets because a
socket has no relevance to software. It's an electromechanical component. In
the past a socket always contained a single package (see below), but with the
advent of Multi Chip Modules (MCM) a socket can hold more than one package. So
there might be still references to sockets in the code, but they are of
historical nature and should be cleaned up.
The topology of a system is described in the units of:
- packages
- cores
- threads
* Package:
Packages contain a number of cores plus shared resources, e.g. DRAM
controller, shared caches etc.
AMD nomenclature for package is 'Node'.
Package-related topology information in the kernel:
- cpuinfo_x86.x86_max_cores:
The number of cores in a package. This information is retrieved via CPUID.
- cpuinfo_x86.phys_proc_id:
The physical ID of the package. This information is retrieved via CPUID
and deduced from the APIC IDs of the cores in the package.
- cpuinfo_x86.logical_id:
The logical ID of the package. As we do not trust BIOSes to enumerate the
packages in a consistent way, we introduced the concept of logical package
ID so we can sanely calculate the number of maximum possible packages in
the system and have the packages enumerated linearly.
- topology_max_packages():
The maximum possible number of packages in the system. Helpful for per
package facilities to preallocate per package information.
* Cores:
A core consists of 1 or more threads. It does not matter whether the threads
are SMT- or CMT-type threads.
AMDs nomenclature for a CMT core is "Compute Unit". The kernel always uses
"core".
Core-related topology information in the kernel:
- smp_num_siblings:
The number of threads in a core. The number of threads in a package can be
calculated by:
threads_per_package = cpuinfo_x86.x86_max_cores * smp_num_siblings
* Threads:
A thread is a single scheduling unit. It's the equivalent to a logical Linux
CPU.
AMDs nomenclature for CMT threads is "Compute Unit Core". The kernel always
uses "thread".
Thread-related topology information in the kernel:
- topology_core_cpumask():
The cpumask contains all online threads in the package to which a thread
belongs.
The number of online threads is also printed in /proc/cpuinfo "siblings."
- topology_sibling_mask():
The cpumask contains all online threads in the core to which a thread
belongs.
- topology_logical_package_id():
The logical package ID to which a thread belongs.
- topology_physical_package_id():
The physical package ID to which a thread belongs.
- topology_core_id();
The ID of the core to which a thread belongs. It is also printed in /proc/cpuinfo
"core_id."
System topology examples
Note:
The alternative Linux CPU enumeration depends on how the BIOS enumerates the
threads. Many BIOSes enumerate all threads 0 first and then all threads 1.
That has the "advantage" that the logical Linux CPU numbers of threads 0 stay
the same whether threads are enabled or not. That's merely an implementation
detail and has no practical impact.
