2009-12-08agp/intel-agp: Clear entire GTT on startupDavid Woodhouse1-1/+6

2009-09-11agp/intel: Fix the pre-9xx chipset flush.Eric Anholt1-7/+23
Ever since we enabled GEM, the pre-9xx chipsets (particularly 865) have had serious stability issues. Back in May a wbinvd was added to the DRM to work around much of the problem. Some failure remained -- easily visible by dragging a window around on an X -retro desktop, or by looking at bugzilla. The chipset flush was on the right track -- hitting the right amount of memory, and it appears to be the only way to flush on these chipsets, but the flush page was mapped uncached. As a result, the writes trying to clear the writeback cache ended up bypassing the cache, and not flushing anything! The wbinvd would flush out other writeback data and often cause the data we wanted to get flushed, but not always. By removing the setting of the page to UC and instead just clflushing the data we write to try to flush it, we get the desired behavior with no wbinvd. This exports clflush_cache_range(), which was laying around and happened to basically match the code I was otherwise going to copy from the DRM.

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?)

On the GM45, the amount of stolen memory mapped to the GTT was underestimated, even though we had 508KB more available since the GTT doesn't take from stolen memory. On the non-GM45 G4X, we overestimated how much stolen was mapped to the GTT by 4KB, resulting in GPU page faults when that page was accessed.

2008-08-12intel/agp: rewrite GTT on resumeKeith Packard1-0/+5
On my Intel chipset (965GM), the GTT is entirely erased across suspend/resume. This patch simply re-plays the current mapping at resume time to restore the table.=20 I noticed this once I started relying on persistent GTT mappings across VT switch in our GEM work -- the old X server and DRM code carefully unbind all memory from the GTT on VT switch, but GEM does not bother. I placed the list management and rewrite code in the generic layer on the assumption that it will be needed on other hardware, but I did not add the rewrite call to anything other than the Intel resume function. Keep a list of current GATT mappings. At resume time, rewrite them into the GATT. This is needed on Intel (at least) as the entire GATT is cleared across suspend/resume.

2008-06-19agp: two-stage page destruction issueJan Beulich1-2/+4
besides it apparently being useful only in 2.6.24 (the changes in 2.6.25 really mean that it could be converted back to a single-stage mechanism), I'm seeing an issue in Xen Dom0 kernels, which is caused by the calling of gart_to_virt() in the second stage invocations of the destroy function. I think that besides this being a real issue with Xen (where unmap_page_from_agp() is not just a page table attribute change), this also is invalid from a theoretical perspective: One should not assume that gart_to_virt() is still valid after unmapping a page. So minimally (keeping the 2-stage mechanism) a patch like the one below would be needed. Jan Signed-off-by: Dave Airlie <airlied@redhat.com>
