Evan Green <evan@rivosinc.com> says: The CPUPERF0 hwprobe key was documented and identified in code as a bitmask value, but its contents were an enum. This produced incorrect behavior in conjunction with the WHICH_CPUS hwprobe flag. The first patch in this series fixes the bitmask/enum problem by creating a new hwprobe key that returns the same data, but is properly described as a value instead of a bitmask. The second patch renames the value definitions in preparation for adding vector misaligned access info. As of this version, the old defines are kept in place to maintain source compatibility with older userspace programs. * b4-shazam-merge: RISC-V: hwprobe: Add SCALAR to misaligned perf defines RISC-V: hwprobe: Add MISALIGNED_PERF key Link: https://lore.kernel.org/r/20240809214444.3257596-1-evan@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
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.
