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.

To reduce tlb/cache flush, makes agp memory allocation do one flush after all pages in a region are changed to uc. All agp drivers except agp-sgi uses agp_generic_alloc_page() for .agp_alloc_page, so the patch should work for them. agp-sgi is only for ia64, so not a problem too.

On my Intel chipset (965GM), the GTT is entirely erased across suspend/resume. This patch simply re-plays the current mapping at resume time to restore the table.=20 I noticed this once I started relying on persistent GTT mappings across VT switch in our GEM work -- the old X server and DRM code carefully unbind all memory from the GTT on VT switch, but GEM does not bother. I placed the list management and rewrite code in the generic layer on the assumption that it will be needed on other hardware, but I did not add the rewrite call to anything other than the Intel resume function. Keep a list of current GATT mappings. At resume time, rewrite them into the GATT. This is needed on Intel (at least) as the entire GATT is cleared across suspend/resume.

I think the intent was that if no bridges matched agp_amd64_pci_table[], we would fall back to checking for any bridge with the AGP capability. But in the current code, we execute the fallback path only when pci_register_driver() itself fails, which is unrelated to whether any matching devices were found. This patch counts the AGP bridges found in the probe() method and executes the fallback path when none is found.

由 Jan Beulich 提交于
besides it apparently being useful only in 2.6.24 (the changes in 2.6.25 really mean that it could be converted back to a single-stage mechanism), I'm seeing an issue in Xen Dom0 kernels, which is caused by the calling of gart_to_virt() in the second stage invocations of the destroy function. I think that besides this being a real issue with Xen (where unmap_page_from_agp() is not just a page table attribute change), this also is invalid from a theoretical perspective: One should not assume that gart_to_virt() is still valid after unmapping a page. So minimally (keeping the 2-stage mechanism) a patch like the one below would be needed. Jan Signed-off-by: NDave Airlie <airlied@redhat.com>

some systems are using 32M for gart and agp when memory is less than 4G. Kernel will reject and try to allcate another 64M that is not needed, and we will waste 64M of perfectly good RAM. this patch adds a workaround by checking aper_base/order between NB and agp bridge. If they are the same, and memory size is less than 4G, it will allow it.

while looking at Rafael J. Wysocki's system boot log, I found a funny printout: Node 0: aperture @ de000000 size 32 MB Aperture too small (32 MB) AGP bridge at 00:04:00 Aperture from AGP @ de000000 size 4096 MB (APSIZE 0) Aperture too small (0 MB) Your BIOS doesn't leave a aperture memory hole Please enable the IOMMU option in the BIOS setup This costs you 64 MB of RAM Mapping aperture over 65536 KB of RAM @ 4000000 ... agpgart: Detected AGP bridge 20 agpgart: Aperture pointing to RAM agpgart: Aperture from AGP @ de000000 size 4096 MB agpgart: Aperture too small (0 MB) agpgart: No usable aperture found. agpgart: Consider rebooting with iommu=memaper=2 to get a good aperture. it means BIOS allocated the correct gart on the NB and AGP bridge, but because a bug in the silicon (the agp bridge reports the wrong order, it wants 4G instead) the kernel will reject that allocation. Also, because the size is only 32MB, and we try to get another 64M for gart, late fix_northbridge can not revert that change because it still reads the wrong size from agp bridge. So try to double check the order value from the agp bridge, before calling aperture_valid().

由 Arjan van dev Ven 提交于
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.
