* agp: kill phys_to_gart() and gart_to_phys()David Woodhouse2009-08-03
| | | | | | | 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 Woodhouse2009-08-03
| | | | | | | | | | | 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 Airlie2009-06-18
| | | | | | | | | 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: enable optimized agp_alloc_pages methodsRene Herman2008-08-22
| | | | | | | | | | | | | | 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.

* fix historic ioremap() abuse in AGPArjan van dev Ven2008-02-18
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [AGPGART] Allow drm-populated agp memory typesThomas Hellstrom2007-02-03
| | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] fix more missing includesTim Schmielau2006-01-08
| | | | | | | | | | Include fixes for 2.6.14-git11. Should allow to remove sched.h from module.h on i386, x86_64, arm, ia64, ppc, ppc64, and s390. Probably more to come since I haven't yet checked the other archs.

* | [PATCH] fix missing includesTim Schmielau2005-10-30
|/ | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] AGP fix for Xen VMMKeir Fraser2005-06-07
| | | | | | | | | | | | | | | | | | | 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.

* Linux-2.6.12-rc2Linus Torvalds2005-04-16
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!
