2007-01-22Revert "[PATCH] Fix up mmap_kmem"Linus Torvalds
This reverts commit 99a10a60ba9bedcf5d70ef81414d3e03816afa3f. As per Hugh Dickins: "Nadia Derbey has reported that mmap of /dev/kmem no longer works with the kernel virtual address as offset, and Franck has confirmed that his patch came from a misunderstanding of what an offset means to /dev/kmem - whereas his patch description seems to say that he was correcting the offset on a few plaforms, there was no such problem to correct, and his patch was in fact changing its API on all platforms."

2007-01-11[PATCH] intel-rng workaroundsJan Beulich
Add a load option to intel-rng to allow skipping the FWH detection, necessary in case the BIOS has locked read-only the firmware hub space. Also prevent any attempt to write to firmware space if it cannot be write enabled (apparently caused hangs on some systems not having an FWH and thus also not having a respective RNG).

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.

2006-12-22[AGPGART] Remove unnecessary flushes when inserting and removing pages.Thomas Hellstrom
This patch is to speed up flipping of pages in and out of the AGP aperture as needed by the new drm memory manager. A number of global cache flushes are removed as well as some PCI posting flushes. The following guidelines have been used: 1) Memory that is only mapped uncached and that has been subject to a global cache flush after the mapping was changed to uncached does not need any more cache flushes. Neither before binding to the aperture nor after unbinding. 2) Only do one PCI posting flush after a sequence of writes modifying page entries in the GATT.
