* agp: kill phys_to_gart() and gart_to_phys()David Woodhouse2009-08-031-1/+1
| | | | | | | There seems to be no reason for these -- they're a 1:1 mapping on all platforms. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* agp: Switch mask_memory() method to take address argument again, not pageDavid Woodhouse2009-08-031-4/+4
| | | | | | | | | | | In commit 07613ba2 ("agp: switch AGP to use page array instead of unsigned long array") we switched the mask_memory() method to take a 'struct page *' instead of an address. This is painful, because in some cases it has to be an IOMMU-mapped virtual bus address (in fact, shouldn't it _always_ be a dma_addr_t returned from pci_map_xxx(), and we just happen to get lucky most of the time?)

* agp: switch AGP to use page array instead of unsigned long arrayDave Airlie2009-06-191-4/+5
| | | | | | | | | This switches AGP to use an array of pages for tracking the pages allocated to the GART. This should enable GEM on PAE to work a lot better as we can pass highmem pages to the PAT code and it will do the right thing with them. Signed-off-by: Dave Airlie <airlied@redhat.com>

* agp: don't lock pagesNick Piggin2007-07-271-1/+0
| | | | | | | | | | AGP should not need to lock pages. They are not protecting any race because there is no lock_page calls, only SetPageLocked. This is causing hangs with d00806b183152af6d24f46f0c33f14162ca1262a. Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Dave Airlie <airlied@redhat.com>

* [AGPGART] Allow drm-populated agp memory typesThomas Hellstrom2007-02-031-0/+1
| | | | | | | | | | | | | | | | | | | | 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.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+331
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!
