  • a32073bff   [PATCH] x86_64: Clean and enhance up K8 northbridge access code ... Browse Code »

    - Factor out the duplicated access/cache code into a single file
    * Shared between i386/x86-64.
    - Share flush code between AGP and IOMMU
    * Fix a bug: AGP didn't wait for end of flush before
    - Drop 8 northbridges limit and allocate dynamically
    - Add lock to serialize AGP and IOMMU GART flushes
    - Add PCI ID for next AMD northbridge
    - Random related cleanups

    The old K8 NUMA discovery code is unchanged. New systems
    should all use SRAT for this.

  • 7c2d9cd21   [PATCH] x86_64: trivial gart clean-up ... Browse Code »

    A trivial change to have gart_unmap_sg call gart_unmap_single directly,
    instead of bouncing through the dma_unmap_single wrapper in
    dma-mapping.h.

    This change required moving the gart_unmap_single above gart_unmap_sg,
    and under gart_map_single (which seems a more logical place that its
    current location IMHO).

  • f0f2d6536   [PATCH] x86_64: Implement compat functions for PTRACE_SETSIGINFO/GETSIGINFO ... Browse Code »

    Previously we would just silently provide 64 bit services
    for this to 32bit processes.

    I also added all the other cases explicitely to the ptrace
    compat wrapper to make sure this doesn't happen again.

    And removed one bogus check in the wrapper.

    Allow search for a contiguous block of iommu space to cross the next_bit
    marker if we have already committed ourselves to flushing the gart.

    There shouldn't be any reason why we'd restrict the search.

    enable large bzImages on x86_64. (fix is from x86's build.c) Using this
    patch i have successfully built and booted an allyesconfig 13MB+ bzImage
    on x86_64 too:

  • d167a5187   [PATCH] x86_64: x86_64 version of the smp alternative patch. ... Browse Code »

    Changes are largely identical to the i386 version:

    * alternative #define are moved to the new alternative.h file.
    * one new elf section with pointers to the lock prefixes which can be
    nop'ed out for non-smp.
    * two new elf sections simliar to the "classic" alternatives to
    replace SMP code with simpler UP code.
    * fixup headers to use alternative.h instead of defining their own
    LOCK / LOCK_PREFIX macros.

    The patch reuses the i386 version of the alternatives code to avoid code
    duplication. The code in alternatives.c was shuffled around a bit to
    reduce the number of #ifdefs needed. It also got some tweaks needed for
    x86_64 (vsyscall page handling) and new features (noreplacement option
    which was x86_64 only up to now). Debug printk's are changed from
    compile-time to runtime.

    Loosely based on a early version from Bastian Blank

  • 240cd6a80   [PATCH] i386/x86-64: Emulate CPUID4 on AMD ... Browse Code »

    Intel systems report the cache level data from CPUID 4 in sysfs.
    Add a CPUID 4 emulation for AMD CPUs to report the same
    information for them. This allows programs to read this
    information in a uniform way.

    The AMD way to report this is less flexible so some assumptions
    are hardcoded (e.g. no L3)

  • faee9a5dc   [PATCH] i386/x86-64: Use new official CPUID to get APICID/core split on AMD platforms ... Browse Code »

    Previously the apicidcoreid split was computed based on the max
    number of cores. Now use a new CPUID AMD defined for that. On most
    systems right now it should be 0 and the old method will be used.

  • 0f4fdb7fb   [PATCH] x86_64: Use local APIC ID from local APIC instead of CPUID ... Browse Code »

    vSMPowered systems use apic_cluster too. Forcing apic_physflat works
    on these systems too, but only if we change phys_pkg_id to use
    hard_smp_prcoessor_id() instead of cpuid_ebx. I am guessing other
    multichassi cluster systems would need this too.

    Kernel image should be somewhat bigger now because of the unwind
    information being included, but you'll get exact backtraces for that.
