  • 464fd83e8   MIPS: Limit fixrange_init() to the FIXMAP region ... Browse Code »

    fixrange_init() allocates page tables for all addresses higher than
    FIXADDR_TOP. On processors that override the default FIXADDR_TOP
    address of 0xfffe_0000, this can consume up to 4 pages (1 page per 4MB)
    for pgd's that are never used.

  • f8829caee   [MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_page ... Browse Code »

    The current implementation uses a sequence of a cacheflush and a copy.
    This is racy in case of a multithreaded debuggee and renders GDB
    virtually unusable.

    Aside this fixes a performance hog rendering access to /proc/cmdline very
    slow and resulting in a enough cache stalls for the 34K AP/SP programming
    model to make the bare metal code on the non-Linux VPE miss RT deadlines.

    The main part of this patch was originally written by Ralf Baechle;
    Atushi Nemoto did the the debugging.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
