KVM selftests updates for 6.2 perf_util: - Add support for pinning vCPUs in dirty_log_perf_test. - Add a lightweight psuedo RNG for guest use, and use it to randomize the access pattern and write vs. read percentage in the so called "perf util" tests. - Rename the so called "perf_util" framework to "memstress". ucall: - Add a common pool-based ucall implementation (code dedup and pre-work for running SEV (and beyond) guests in selftests. - Fix an issue in ARM's single-step test when using the new pool-based implementation; LDREX/STREX don't play nice with single-step exceptions. init: - Provide a common constructor and arch hook, which will eventually be used by x86 to automatically select the right hypercall (AMD vs. Intel). x86: - Clean up x86's page tabe management. - Clean up and enhance the "smaller maxphyaddr" test, and add a related test to cover generic emulation failure. - Clean up the nEPT support checks. - Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
