2007-02-06Implement a policy for selecting memory types.Thomas Hellstrom
2007-02-05i915: Add copy-blit operation.Thomas Hellstrom
2007-02-02Make vm handle buffer objects instead of ttm objects.Thomas Hellstrom
Remove ttm objects. Make vm aware of PCI memory type buffer objects. (Only works for pre 2.6.16 kernels for now).
2007-01-31memory manager: Make device driver aware of different memory types.Thomas Hellstrom
Memory types are either fixed (on-card or pre-bound AGP) or not fixed (dynamically bound) to an aperture. They also carry information about: 1) Whether they can be mapped cached. 2) Whether they are at all mappable. 3) Whether they need an ioremap to be accessible from kernel space. In this way VRAM memory and, for example, pre-bound AGP appear identical to the memory manager. This also makes support for unmappable VRAM simple to implement.

driver we're on. Avoid global cache flushes before inserting pages. In general, they are never mapped, and not accessed through the kernel map, so a cache flush should not be necessary. The exception is pages that are bound cached. We might need a cache flush for those.

2006-10-16Change Intel AGP memory type numbers.Thomas Hellstrom
2006-10-12Simplify the AGP backend interface somewhat.Thomas Hellstrom
Fix buffer bound caching policy changing, Allow on-the-fly changing of caching policy on bound buffers if the hardware supports it. Allow drivers to use driver-specific AGP memory types for TTM AGP pages. Will make AGP drivers much easier to migrate.
