2007-02-03[AGPGART] Allow drm-populated agp memory typesThomas Hellstrom
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.

2006-12-22[AGPGART] fix detection of aperture size versus GTT size on G965Eric Anholt
On the G965, the GTT size may be larger than is required to cover the aperture. (In fact, on all hardware we've seen, the GTT is 512KB to the aperture's 256MB). A previous commit forced the aperture size to 512MB on G965 to match GTT, which would likely result in hangs at best if users tried to rely on agpgart's aperture size information. Instead, we use the resource length for the aperture size and the system's reported GTT size when available for the GTT size. Because the MSAC registers which had been read for aperture size detection on i9xx chips just cause a change in the resource size, we can use generic code for aperture detection on all i9xx.

2005-07-29[PATCH] agp: restore APBASE after setting APSIZEMatthew Garrett
When leaving S3 state, the AGP bridge may not have all PCI configuration registers set in the same way as they were at boot. This should be fixed by pci_restore_state - however, the APBASE register cannot be set to conflict with the APSIZE register. If APSIZE is larger than it was before suspend, pci_restore_state will not restore APBASE correctly. The attached patch adds an extra item to the agp_bridge_data structure and uses it to store the value of APBASE. On resume, this is then written after APSIZE has been set. This patch only touches the path used for Intel chipsets without integrated graphics, and may need to be extended to work with the others. Without this patch, I get the symptoms described in bug 4921 - APBASE ends up overlapping various PCI devices, and as a result they fail to work after resume.

2005-06-07[PATCH] AGP fix for Xen VMMKeir Fraser
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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
