Pull x86 resource control updates from Borislav Petkov: - Add support for AMD's Smart Data Cache Injection feature which allows for direct insertion of data from I/O devices into the L3 cache, thus bypassing DRAM and saving its bandwidth; the resctrl side of the feature allows the size of the L3 used for data injection to be controlled - Add Intel Clearwater Forest to the list of CPUs which support Sub-NUMA clustering - Other fixes and cleanups * tag 'x86_cache_for_v6.19_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: fs/resctrl: Update bit_usage to reflect io_alloc fs/resctrl: Introduce interface to modify io_alloc capacity bitmasks fs/resctrl: Modify struct rdt_parse_data to pass mode and CLOSID fs/resctrl: Introduce interface to display io_alloc CBMs fs/resctrl: Add user interface to enable/disable io_alloc feature fs/resctrl: Introduce interface to display "io_alloc" support x86,fs/resctrl: Implement "io_alloc" enable/disable handlers x86,fs/resctrl: Detect io_alloc feature x86/resctrl: Add SDCIAE feature in the command line options x86/cpufeatures: Add support for L3 Smart Data Cache Injection Allocation Enforcement fs/resctrl: Consider sparse masks when initializing new group's allocation x86/resctrl: Support Sub-NUMA Cluster (SNC) mode on Clearwater Forest
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 reStructuredText 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.
