Alexandre Ghiti <alexghiti@rivosinc.com> says: This series optimizes the tlb flushes on riscv which used to simply flush the whole tlb whatever the size of the range to flush or the size of the stride. Patch 3 introduces a threshold that is microarchitecture specific and will very likely be modified by vendors, not sure though which mechanism we'll use to do that (dt? alternatives? vendor initialization code?). * b4-shazam-merge: riscv: Improve flush_tlb_kernel_range() riscv: Make __flush_tlb_range() loop over pte instead of flushing the whole tlb riscv: Improve flush_tlb_range() for hugetlb pages riscv: Improve tlb_flush() Link: https://lore.kernel.org/r/20231030133027.19542-1-alexghiti@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 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.
