  • 5f310b637   agp: enable optimized agp_alloc_pages methods ... Browse Code »

    The pageattr-array patch that you currently have in tip/master only
    enables it for intel-agp, not the others. The attached enables it for
    all drivers currently directly using agp_generic_alloc_page() and
    agp_generic_destroy_page() (ocal driver is amd-k7-agp).

    The new agp_generic_alloc_pages() interface uses the also new
    pageattr array interface API. This makes all AGP drivers that
    up to now used generic_{alloc,destroy}_page() use it.

  • fcea424d3   fix historic ioremap() abuse in AGP ... Browse Code »

    Several AGP drivers right now use ioremap_nocache() on kernel ram in order
    to turn a page of regular memory uncached.

    There are two problems with this:

    1) This is a total nightmare for the ioremap() implementation to keep
    various mappings of the same page coherent.

    2) It's a total nightmare for the AGP code since it adds a ton of
    complexity in terms of keeping track of 2 different pointers to
    the same thing, in terms of error handling etc etc.

    This patch fixes this by making the AGP drivers use the new
    set_memory_XX APIs instead.

    Note: amd-k7-agp.c is built on Alpha too, and generic.c is built
    on ia64 as well, which do not yet have the set_memory_*() APIs,
    so for them some we have a few ugly #ifdefs - hopefully they'll
    be fixed soon.

  • 190644e18   Fix "use after free" / "double free" bug in ati_create_gatt_pages / ati_free_gatt_pages ... Browse Code »

    Hi,

    Coverity spotted a "use after free" bug in
    drivers/char/agp/ati-agp.c::ati_create_gatt_pages().

    The same one that was in
    drivers/char/agp/amd-k7-agp.c::amd_create_gatt_pages()

    The problem is this:
    If "entry = kzalloc(sizeof(struct ati_page_map), GFP_KERNEL);"
    fails, then there's a loop in the function to free all entries
    allocated so far and break out of the allocation loop. That in itself
    is pretty sane, but then the (now freed) 'tables' is assigned to
    ati_generic_private.gatt_pages and 'retval' is set to -ENOMEM which
    causes ati_free_gatt_pages(); to be called at the end of the function.
    The problem with this is that ati_free_gatt_pages() will then loop
    'ati_generic_private.num_tables' times and try to free each entry in
    tables[] - this is bad since tables has already been freed and
    furthermore it will call kfree(tables) at the end - a double free.

    This patch removes the freeing loop in ati_create_gatt_pages() and
    instead relies entirely on the call to ati_free_gatt_pages() to free
    everything we allocated in case of an error. It also sets
    ati_generic_private.num_tables to the actual number of entries
    allocated instead of just using the value passed in from the caller -
    this ensures that ati_free_gatt_pages() will only attempt to free
    stuff that was actually allocated.

    Note: I'm in no way intimate with this code and I have no way to
    actually test this patch (besides compile test it), so while I've
    tried to be careful in reading the code and make sure the patch
    does the right thing an ACK from someone who actually knows the
    code in-depth would be very much appreciated.

  • a030ce447   [AGPGART] Allow drm-populated agp memory types ... Browse Code »

    This patch allows drm to populate an agpgart structure with pages of its own.
    It's needed for the new drm memory manager which dynamically flips pages in and out of AGP.

    The patch modifies the generic functions as well as the intel agp driver. The intel drm driver is
    currently the only one supporting the new memory manager.

    Other agp drivers may need some minor fixing up once they have a corresponding memory manager enabled drm driver.

    AGP memory types >= AGP_USER_TYPES are not populated by the agpgart driver, but the drm is expected
    to do that, as well as taking care of cache- and tlb flushing when needed.

    It's not possible to request these types from user space using agpgart ioctls.

    The Intel driver also gets a new memory type for pages that can be bound cached to the intel GTT.

  • 4e57b6817   [PATCH] fix missing includes ... Browse Code »

    I recently picked up my older work to remove unnecessary #includes of
    sched.h, starting from a patch by Dave Jones to not include sched.h
    from module.h. This reduces the number of indirect includes of sched.h
    by ~300. Another ~400 pointless direct includes can be removed after
    this disentangling (patch to follow later).
    However, quite a few indirect includes need to be fixed up for this.

    In order to feed the patches through -mm with as little disturbance as
    possible, I've split out the fixes I accumulated up to now (complete for
    i386 and x86_64, more archs to follow later) and post them before the real
    patch. This way this large part of the patch is kept simple with only
    adding #includes, and all hunks are independent of each other. So if any
    hunk rejects or gets in the way of other patches, just drop it. My scripts
    will pick it up again in the next round.

    This allows SYSFS to create the symlink from the driver to the module which
    provides it.

  • 07eee78ea   [PATCH] AGP fix for Xen VMM ... Browse Code »

    When Linux is running on the Xen virtual machine monitor, physical
    addresses are virtualised and cannot be directly referenced by the AGP
    GART. This patch fixes the GART driver for Xen by adding a layer of
    abstraction between physical addresses and 'GART addresses'.

    Architecture-specific functions are also defined for allocating and freeing
    the GATT. Xen requires this to ensure that table really is contiguous from
    the point of view of the GART.

    These extra interface functions are defined as 'no-ops' for all existing
    architectures that use the GART driver.

    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!
