  • cdef24c9c   [IA64] aliasing-test: fix gcc warnings on non-ia64 ... Browse Code »

    Eliminate all build warnings. OK, these build warnings are from
    a build on x86_64. When I build on ia64, I don't see warnings.

    Now builds cleanly on ia64 and x86_64.

  • 01dd2fbf0   typo fixes ... Browse Code »

    Most of these fixes were already submitted for old kernel versions, and were
    approved, but for some reason they never made it into the releases.

    Because this is a consolidation of a couple old missed patches, it touches both
    Kconfigs and documentation texts.

  • 012b7105c   [IA64] prevent MCA when performing MMIO mmap to PCI config space ... Browse Code »

    Example memory map (HP rx7640 with 'default' acpiconfig setting, VGA disabled):
    0x00000000 - 0x3FFFBFFF supports only WB (cacheable) access

    If a user attempts to perform an MMIO mmap (using the PCIIOC_MMAP_IS_MEM ioctl)
    to PCI config space (like mmap'ing and accessing memory at 0xA0000),
    we will MCA because the kernel will attempt to use a mapping with the UC
    attribute.

    So check the memory attribute in kern_mmap and the EFI memmap. If WC is
    requested, and WC or UC access is supported for the region, allow it.
    Otherwise, use the same attribute the kernel uses.

    Updates documentation and test cases as well.

    Fix various bits of obviously-busted code which we're not happening to
    compile, due to ifdefs.

  • bf6285278   [IA64] Itanium MC Error Injection Tool: Doc and sample application ... Browse Code »

    This patch contains a documention and sample application. Since the sample
    application has ~1000 lines of code, it might not be suitable in a kernel
    documention in kenrel tree. If you think this is not good place to hold
    the sample application, please let me know and I'm open to other choices
    e.g. sourceforge etc.

  • 32e62c636   [IA64] rework memory attribute aliasing ... Browse Code »

    This closes a couple holes in our attribute aliasing avoidance scheme:

    - The current kernel fails mmaps of some /dev/mem MMIO regions because
    they don't appear in the EFI memory map. This keeps X from working
    on the Intel Tiger box.

    - The current kernel allows UC mmap of the 0-1MB region of
    /sys/.../legacy_mem even when the chipset doesn't support UC
    access. This causes an MCA when starting X on HP rx7620 and rx8620
    boxes in the default configuration.

    There's more detail in the Documentation/ia64/aliasing.txt file this
    adds, but the general idea is that if a region might be covered by
    a granule-sized kernel identity mapping, any access via /dev/mem or
    mmap must use the same attribute as the identity mapping.

    Otherwise, we fall back to using an attribute that is supported
    according to the EFI memory map, or to using UC if the EFI memory
    map doesn't mention the region.

    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!
