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.

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.

Current X86-64 implementations only support 40 bits of address space,

but we support up to 46 bits. This expands into MBZ space in the page tables.

Current X86-64 implementations support up to 46 bits of address space (64 TB),
|

which is our current limit. This expands into MBZ space in the page tables.

We map EFI runtime services in the 'efi_pgd' PGD in a 64Gb large virtual
|
||||
memory window (this size is arbitrary, it can be raised later if needed).
