  • 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.

    Documentation/ia64/aliasing-test.c:39: warning: implicit declaration of function 'ioctl'

  • 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.
