2010-12-07intel: Reorder need_fence vs fenced_command to avoid fences on gen4Chris Wilson
gen4+ hardware doesn't use fences for GPU access and the older kernel doesn't expect userspace to make such a mistake. So don't. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=32190 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-11-25intel: Add a forward declaration of struct drm_clip_rectChris Wilson
... so that intel_bufmgr.h can be compiled standalone. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-11-22intel: Compute in-aperture size for relaxed fenced objectsChris Wilson
For relaxed fencing the object may only consume the small set of active pages, but still requires a fence region once bound into the aperture. This is the size we need to use when computing the maximum possible aperture space that could be used by a single batchbuffer and so avoid hitting ENOSPC. Reported-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-11-09intel: Fix drm_intel_gem_bo_wait_rendering to wait for read-only usage too.Eric Anholt
Both the consumers of this API (sync objects and client throttling) were expecting this behavior. The kernel used to actually behave the desired (but incorrect) way for us anyway, but that got fixed a while back.
2010-11-07intel: initialize bufmgr.bo_mrb_exec unconditionallyAlbert Damen
If bufmgr.bo_mrb_exec is not set, drm_intel_bo_mrb_exec returns ENODEV even though drm_intel_gem_bo_mrb_exec2 will work fine for the RENDER ring. Fixes xf86-video-intel after commit 'add BLT ring support' (5bed685f76) with kernels without BSD or BLT ring support (2.6.34 and before).

2010-11-02intel: Drop silly asserts on mappings present at unmap time.Eric Anholt
The intent of these was to catch mismatched map/unmap. What it actually did was check whether there was ever a mapping of that type (including in a previous life of the buffer through the userland BO cache), not whether they were mismatched. We don't even actually want to catch mismatched map/unmap, unless we also do refcounting, since at one point Mesa would do map/map/use/unmap/unmap. Just remove this code instead.
2010-11-02intel: Remove gratuitous assert on bo_reference.Eric Anholt
This couldn't be triggered except by overflow, since there's an assert in unreference to catch the usual failure of over-unreferencing.
2010-11-01intel: Shove the fake bufmgr subdata implementation into the fake bufmgr.Eric Anholt
2010-11-01intel: Remove stale comment.Eric Anholt
2010-10-29intel: enable relaxed fence allocation for i915Chris Wilson
The kernel has always allowed userspace to underallocate objects supplied for fencing. However, the kernel only allocated the object size for the fence in the GTT and so caused tiling corruption. More recently the kernel does allocate the full fence region in the GTT for an under-sized object and so advertises that clients may finally make use of this feature. The biggest benefit is for texture-heavy GL games on i945 such as World of Padman which go from needing over 1GiB of RAM to play to fitting in the GTT!

2010-10-01intel: Downgrade error warnings to debugChris Wilson
As the higher layers check the error return from libdrm-intel and are supposed to handle the error (and print their own warning in extremis) the voluminous output on stderr is just noise and a hazard in its own right. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-09-25intel: Replace open-coded drmIoctl with calls to drmIoctl()Chris Wilson

2010-08-26Avoid use of c++ reserved keyword "virtual" when using a C++ compiler.Eric Anholt
Avoids requiring nasty hacks around libdrm headers in the new C++ parts of Mesa drivers.
2010-06-29intel: Suppress the error return from setting domains after mapping.Chris Wilson
If the mapping succeeds we have a valid pointer. If setting the domain failures we may incur cache corruption. However the usual failure mode is because of a hung GPU, in which case it is preferable to ignore the minor error from setting the domain and continue on oblivious. If these errors persist, we should rate limit the warning [or even just remove it]. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-06-24intel: Limit tiled pitches to 8192 on pre-i965.Chris Wilson

2010-06-22intel: Only adjust the local stride used for SET_TILING in tiled allocChris Wilson
Mesa uses the returned pitch from alloc_tiled, so make sure that we set it correctly before modifying the stride used for the SET_TILING call. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-06-22intel: Sanitise strides for linear buffers and SET_TILINGChris Wilson
Ensure that the user doesn't attempt to specify a stride to use with a linear buffer by forcing such to be zero. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-06-21intel: Print out debugging message following ENOSPCChris Wilson
execbuffer() returns ENOSPC if it cannot fit the batch buffer into the aperture which is the error we want to diagnose here. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-06-21intel: Scan the cache for old bo once every second.Chris Wilson
Rearrange the cache cleanup so that we always scan following a final unreference, and guard against multiple scans in a single second. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-06-21intel: Force stride to be 0 for I915_TILING_NONE.Chris Wilson
When allocating a tiled buffer, if we remove the desired tiling mode due to it being beyond hardware limits, also remove the stride. This ensures that we only ever use stride 0 with I915_TILING_NONE. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-06-21intel: Defer tiling change to allocation.Chris Wilson
As we now expose a method to allocate tiled buffers, it makes more sense to defer the SET_TILING until required. Besides the slim chance that it will be a no-op, by delaying the change we are less likely to stall on waiting for a bound buffer to release a fence register. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-06-21intel: Track tiling strideChris Wilson
We need to inform the kernel if the tiling stride changes and not only for changes of the tiling mode. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-06-10intel: Fix several other paths for buffers pointing at themselves.Eric Anholt
2010-06-10intel: Add more intermediate sizes of cache buckets between powers of 2.Eric Anholt
We had two cases recently where the rounding to powers of two hurt badly: 4:2:0 YUV HD video frames would round up from 2.2MB to 4MB, and Urban Terror was hitting aperture size limitations. For UT, this is because mipmap trees for power of two texture sizes will land right in the middle between two cache buckets. By giving a few more sizes between powers of two, Urban Terror on my 945 ends up consuming 207MB of GEM objects instead of 272MB, and HD video decode on Ironlake goes from 99MB to 75MB. cairo-perf-diff of the benchmarks for gl and xlib shows a 1.09x and 1.06x speedup and a 1.07x, 1.08x, and 1.11x slowdown. From this, I think this patch was really a no-op in terms of performance for these CPU-bound workloads.
2010-06-09intel: Convert to untiled pitches if surface is too large for tiling.Chris Wilson
If the pitch is too large for the hardware to tile, recompute the required surface size based on the untiled pitch and alignments. For the older hardware, which has smaller limits and greater restrictions, this may be a considerable saving in allocation size. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-05-24intel: Don't change tiling mode unless the kernel reports success.Chris Wilson
Fixes: Bug 26686 - Some textures are distorted with libdrm 2.4.18 in GTAVC&GTA3 http://bugs.freedesktop.org/show_bug.cgi?id=26686 This bug continues to haunt me. The kernel SET_TILING ioctl is inconsistent in its return values when reporting an error. If one of its sanity checks fail, then the input values are left unchanged. If the kernel later fails to change the tiling mode, then the input values are modified to match the current tiling on the object. In short, userspace cannot trust the return values upon error and so we must assume that upon error our current tiling mode matches reality and not update.
2010-05-13Revert "intel: We don't need to take the bufmgr lock whilst mapping."Chris Wilson
This reverts commit 7ca558494dd3f68f29bb6ca981de9b8f49620b60. This was pushed ahead of an essential review of bo level locking in mesa, without which we cannot know whether removing this lock is safe.
