+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

+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.
+

+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.

+ * between clearing STARTED and clearing the EN bit (in fact multiple NMIs
+ * could happen if the period is small enough), and consume our STOPPED bit
+ * and trigger streams of unhandled NMIs.
+ *
+ * If, however, we clear STARTED late, an NMI can hit between clearing the

Errors in .c files
------------------
-If you're getting an objtool error in a compiled .c file, chances are
-the file uses an asm() statement which has a "call" instruction. An
-asm() statement with a call instruction must declare the use of the
-stack pointer in its output operand. For example, on x86_64:
+1. c_file.o: warning: objtool: funcA() falls through to next function funcB()
- register void *__sp asm("rsp");
- asm volatile("call func" : "+r" (__sp));
+ This means that funcA() doesn't end with a return instruction or an
+ unconditional jump, and that objtool has determined that the function
+ can fall through into the next function. There could be different
+ reasons for this:
-Otherwise the stack frame may not get created before the call.
+ 1) funcA()'s last instruction is a call to a "noreturn" function like
+ panic(). In this case the noreturn function needs to be added to
+ objtool's hard-coded global_noreturns array. Feel free to bug the
+ objtool maintainer, or you can submit a patch.
-Another possible cause for errors in C code is if the Makefile removes
--fno-omit-frame-pointer or adds -fomit-frame-pointer to the gcc options.
+ 2) funcA() uses the unreachable() annotation in a section of code
+ that is actually reachable.
+
+ 3) If funcA() calls an inline function, the object code for funcA()
+ might be corrupt due to a gcc bug. For more details, see:
+ https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70646
+
+2. If you're getting any other objtool error in a compiled .c file, it
+ may be because the file uses an asm() statement which has a "call"
+ instruction. An asm() statement with a call instruction must declare
+ the use of the stack pointer in its output operand. For example, on
+ x86_64:
+
+ register void *__sp asm("rsp");
+ asm volatile("call func" : "+r" (__sp));
+
+ Otherwise the stack frame may not get created before the call.
+
+3. Another possible cause for errors in C code is if the Makefile removes
+ -fno-omit-frame-pointer or adds -fomit-frame-pointer to the gcc options.
Also see the above section for .S file errors for more information what
the individual error messages mean.

+ *
+ * This check is for a rare gcc quirk, currently only seen in
+ * three driver functions in the kernel, only with certain
+ * obscure non-distro configs.
+ *
+ * As part of an optimization, gcc makes a copy of an existing
+ * switch jump table, modifies it, and then hard-codes the jump
+ * (albeit with an indirect jump) to use a single entry in the
+ * table. The rest of the jump table and some of its jump
+ * targets remain as dead code.
+ *
+ * In such a case we can just crudely ignore all unreachable
+ * instruction warnings for the entire object file. Ideally we
+ * would just ignore them for the function, but that would
+ * require redesigning the code quite a bit. And honestly
+ * that's just not worth doing: unreachable instruction
+ * warnings are of questionable value anyway, and this is such
+ * a rare issue.
