2009-08-28Add drm_intel_bo_busy to query whether mapping a BO would block.Eric Anholt
2009-08-28Revert "libdrm_radeon: Always wait for BO idle in bo_map."Michel Dänzer
This reverts commit 0a732983f059c353b267b6bf877e1f0eea4e033f. Paul Nieminen and Dave Airlie pointed out on IRC that this shouldn't be necessary. I was seeing visual corruption in X before I made this change, but I can't reproduce that anymore so it was probably an unrelated issue.
2009-08-27libdrm_radeon: Always wait for BO idle in bo_map.Michel Dänzer
This allows users to eliminate explicit bo_wait calls before bo_map calls.
2009-08-22radeon: add support for busy/domain check interface.Pauli Nieminen
airlied: modified the interface to drop busy return value, just return it normally, also fixed int->uint32_t for domain Signed-off-by: Pauli Nieminen <suokkos@gmail.com>

No idea why G80 doesn't hit this, but, this fixes at least one NV40 card.
2009-08-18libdrm_radeon: Optimize copy of table to cs buffer with specialized call.Pauli Nieminen
Using this call in OUT_BATCH_TABLE reduces radeonEmitState cpu usage from 9% to 5% and emit_vpu goes from 7% to 1.5%. I did use calgrind to profile gears for cpu hotspots with r500 card. Signed-off-by: Pauli Nieminen <suokkos@gmail.com>

2009-07-27libdrm/nouveau: unmap before ufree means nvbo->sysmem != NULL, which ↵Maarten Maathuis
inbalances cpu_prep/cpu_finish - The bo was mapped with sysmem == NULL, so this means cpu prep is called. - The bo was unmapped with sysmem != NULL, so this means cpu finish is not called. - This can lead to a non-zero "cpu writers" count in ttm_bo.
2009-07-09intel: Free buffers in the BO cache that haven't been reused in a while.Eric Anholt
The goal of the BO cache is to keep buffers on hand for fast continuous use, as in every frame of a game or every batchbuffer of the X Server. Keeping older buffers on hand not only doesn't serve this purpose, it may hurt performance by resulting in disk cache getting kicked out, or even driving the system to swap. Bug #20766.

2009-07-06intel: Fix up math errors when allocating very large BOs.Eric Anholt
The logbase2 would overflow and wrap the size around to 0, making the code allocate a 4kb object instead. By simplifying the code to just walk the 14-entry bucket array comparing sizes instead of indexing on ffs(1 << logbase2(size)), we avoid silly math errors and have code of approximately the same speed. Many thanks to Simon Farnsworth for debugging and providing a working patch. Bug #27365.

Based on patch by Pauli Nieminen. Thanks.
2009-07-06radeon: move cs space checking code to libdrm_radeon.Dave Airlie
This ports a lot of the space checking code into a the common library, so that the DDX and mesa can use it.
2009-07-03radeon: fix cs buffer realloc paddingJerome Glisse
We always realloc at least 0x1000 dwords (page on most system) when growing the cs buffer this is to avoid having to realloc at each cs_begin.
2009-07-03radeon: fix realloc of packets.Dave Airlie
This should use ndw not cdw, using cdw leads to realloc alignment going wrong
2009-07-02radeon: add buffer naming functionDave Airlie
2009-06-30radeon: add support for write followed by read relocs.Dave Airlie
the DDX does this and used to handle it internally
2009-06-17libdrm/radeon: add initial libdrm_radeonDave Airlie
requires --enable-radeon-experimental-api for now
2009-06-05nouveau: 0.0.14 + extend bo interface to support subrange mappingBen Skeggs
Normal map() should operate as before, and map_range()/map_flush() should give correct results but lacking any performance difference from map(). Nothing exiting being done here yet, but the interface is a good start.

2009-05-19intel: Only do BO caching up to 64MB objects.Eric Anholt
This avoids making objects significantly bigger than they would be otherwise, which would result in some failing at binding to the GTT. Found from firefox hanging on: http://upload.wikimedia.org/wikipedia/commons/b/b7/Singapore_port_panorama.jpg due to a software fallback trying to do a GTT-mapped copy between two 73MB BOs that were instead each 128MB, and failing because both couldn't fit simultaneously. The cost here is that we get no opportunity to cache these objects and avoid the mapping. But since the objects are a significant percentage of the aperture size, each mapped access is likely having to fault and rebind the object most of the time anyway. Bug #20152 (2/3)
2009-05-14libdrm/intel: Make get_pipe_from_crtc_id per-bufmgr. Return -1 on failure.Keith Packard
The convention is that all APIs are per-bufmgr, so make this one the same. Then, have it return -1 on failure so that the application can know what's going on and do something sensible. Signed-off-by: Keith Packard <keithp@keithp.com>
2009-05-14Add new drm_intel_get_pipe_from_crtc_id function.Carl Worth
This wraps the new DRM_IOCTL_I915_GET_PIPE_FROM_CRTC_ID ioctl, allowing applications to discover the pipe number corresponding to a given CRTC ID. This is necessary for doing pipe-specific operations such as waiting for vblank on a given CRTC.
2009-05-12libdrm/intel: add drm_intel_bo_disable_reuse apiKeith Packard
Scanout buffers need to be freed through the kernel as it holds a reference to them; exposing this API allows applications allocating scanout buffers to flag them as not reusable. Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Eric Anholt <eric@anholt.net>

2009-05-01libdrm/intel: assert that clients are using bo refcounting correctlyKeith Packard
Add assertions to drm_intel_gem_bo_reference, drm_intel_gem_bo_reference_locked and drm_intel_gem_bo_unreference_locked that the object has not been freed (refcount > 0). Mistakes in refcounting lead to attempts to insert a bo into a free list more than once which causes application failure as empty free lists are dereferenced as buffer objects.

2009-04-10Revert "libdrm: speed up connector & mode fetching"Jesse Barnes
This reverts commit cd5c66c659168cbe2e3229ebf8be79f764ed0ee1. It broke too many kernel assumptions about the double ioctl (connector status, mode fetching, etc.)
2009-03-30libdrm: speed up connector & mode fetchingJesse Barnes
This patch speeds up drmModeGetConnector by pre-allocating mode & property info space before calling into the kernel.  In many cases this pre-allocation will be sufficient to hold the returned values (it's easy enough to tweak if the common case becomes larger), which means we don't have to make the second call, which saves a lot of time.

2009-03-26libdrm/intel: support GTT maps correctlyJesse Barnes
libdrm has some support for GTT mapping already, but there are bugs with it (no surprise since it hasn't been used much). In fixing 20803, I found that sharing bo_gem->virtual was a bad idea, since a previously mapped object might not end up getting GTT mapped, leading to corruption. So this patch splits the fields according to use, taking care to unmap both at free time (but preserving the map caching). There's still a risk we might run out of mappings (there's a sysctl tunable for max number of mappings per process, defaulted to 64k or so it looks like) but at least GTT maps will work with these changes (and some others for fixing PAT breakage in the kernel).
