* amd64-agp: fix crash at second module loadFlorian Mickler2011-02-23
| | | | | | | | | | | The module forgot to sometimes unregister some resources. This fixes Bug #22882.

* x86, amd-nb: Cleanup AMD northbridge caching codeHans Rosenfeld2010-11-18
| | | | | | | | | | | | | Support more than just the "Misc Control" part of the northbridges. Support more flags by turning "gart_supported" into a single bit flag that is stored in a flags member. Clean up related code by using a set of functions (amd_nb_num(), amd_nb_has_feature() and node_to_amd_nb()) instead of accessing the NB data structures directly. Reorder the initialization code and put the GART flush words caching in a separate function.

* x86, amd-nb: Complete the rename of AMD NB and related codeHans Rosenfeld2010-11-18
| | | | | | | | | | | | | Not only the naming of the files was confusing, it was even more so for the function and variable names. Renamed the K8 NB and NUMA stuff that is also used on other AMD platforms. This also renames the CONFIG_K8_NUMA option to CONFIG_AMD_NUMA and the related file k8topology_64.c to amdtopology_64.c.

| | | | | | | | | | | | | | | | | | | | | | So far we only provide num_k8_northbridges. This is required in different areas (e.g. L3 cache index disable, GART). But not all AMD CPUs provide a GART.

| | | | | | | | | | | | | | The current initialisation code probes 'unsupported' AGP devices simply by calling its own probe function. It does not lock these devices or even check whether another driver is already bound to them. We must use the device core to manage this.

* x86/agp: Fix amd64-agp module initialization regressionFUJITA Tomonori2010-02-04

The commit 61684ceaad4f65d1a9832c722f7bd5e7fc714de9 fixed the above regression but it's not enough. When amd64-agp is built as a module, AGP isn't initialized, iommu is initialized, all the aperture is owned by the iommu.

* x86/agp: Fix agp_amd64_init regressionFUJITA Tomonori2010-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the regression introduced by commit 42590a75019a50012f25a962246498dead428433 ("x86/agp: Fix agp_amd64_init and agp_amd64_cleanup"). The above commit changes agp_amd64_init() not to do anything if gart_iommu_aperture is not zero. If GART iommu calls agp_amd64_init(), we need to skip agp_amd64_init() when it's called later via module_init. The problem is that gart_iommu_init() calls agp_amd64_init() with not zero gart_iommu_aperture so agp_amd64_init() is never initialized. When gart_iommu_init() calls agp_amd64_init(), agp should be always initialized.

Also, because the size is only 32MB, and we try to get another 64M for gart, late fix_northbridge can not revert that change because it still reads the wrong size from agp bridge.

In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.

* [AGPGART] Allow drm-populated agp memory typesThomas Hellstrom2007-02-03
| | | | | | | | | | | | | | | | | | | | 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.

| * [PATCH] x86_64: Rename IOMMU option, fix help and mark option embedded.Andi Kleen2006-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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?

| * [PATCH] x86_64: Clean and enhance up K8 northbridge access codeAndi Kleen2006-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.
