[PATCH] AGP: Allocate AGP pages with GFP_DMA32 by default

2006-12-02T00:12:37+00:00

Not all graphic page remappers support physical addresses over the 4GB mark for remapping, so while some do (the AMD64 GART always did, and I just fixed the i965 to do so properly), we're safest off just forcing GFP_DMA32 allocations to make sure graphics pages get allocated in the low 32-bit address space by default. AGP sub-drivers that really care, and can do better, could just choose to implement their own allocator (or we could add another "64-bit safe" default allocator for their use), but quite frankly, you're not likely to care in practice. So for now, this trivial change means that we won't be allocating pages that we can't map correctly by mistake on x86-64. [ On traditional 32-bit x86, this could never happen, because GFP_KERNEL would never allocate any highmem memory anyway ] Acked-by: Andi Kleen Acked-by: Dave Jones Cc: Eric Anholt Cc: Keith Packard Signed-off-by: Linus Torvalds Signed-off-by: Chris Wright

[PATCH] make more file_operation structs static

2006-07-03T22:26:59+00:00

Mark the static struct file_operations in drivers/char as const. Making them const prevents accidental bugs, and moves them to the .rodata section so that they no longer do any false sharing; in addition with the proper debug option they are then protected against corruption..

[PATCH] x86_64: Rename IOMMU option, fix help and mark option embedded.

2006-06-26T17:48:17+00:00

- Rename the GART_IOMMU option to IOMMU to make clear it's not just for AMD - Rewrite the help text to better emphatise this fact - Make it an embedded option because too many people get it wrong. To my astonishment I discovered the aacraid driver tests this symbol directly. This looks quite broken to me - it's an internal implementation detail of the PCI DMA API. Can the maintainer please clarify what this test was intended to do? Cc: linux-scsi@vger.kernel.org Cc: alan@redhat.com Cc: markh@osdl.org Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

[PATCH] x86_64: Clean and enhance up K8 northbridge access code

2006-06-26T17:48:15+00:00

- Factor out the duplicated access/cache code into a single file * Shared between i386/x86-64. - Share flush code between AGP and IOMMU * Fix a bug: AGP didn't wait for end of flush before - Drop 8 northbridges limit and allocate dynamically - Add lock to serialize AGP and IOMMU GART flushes - Add PCI ID for next AMD northbridge - Random related cleanups The old K8 NUMA discovery code is unchanged. New systems should all use SRAT for this. Cc: "Navin Boppuri" Cc: Dave Jones Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds
