2014-09-17intel: Add support for userptr objectsTvrtko Ursulin
Allow userptr objects to be created and used via libdrm_intel. At the moment tiling and mapping to GTT aperture is not supported due hardware limitations across different generations and uncertainty about its usefulness. v2: Improved error handling in feature detection per review comments. v3: Rebase on top of the drm_public addition, minor whitespace addition.

2014-01-20intel: Create a new drm_intel_bo offset64 field.Kenneth Graunke
The existing 'offset' field is unfortunately typed as 'unsigned long', which is unfortunately only 4 bytes with a 32-bit userspace. Traditionally, the hardware has only supported 32-bit virtual addresses, so even though the kernel uses a __u64, the value would always fit. However, Broadwell supports 48-bit addressing. So with a 64-bit kernel, the card virtual address may be too large to fit in the 'offset' field. Ideally, we would change the type of 'offset' to be a uint64_t---but this would break the libdrm ABI. Instead, we create a new 'offset64' field to hold the full 64-bit value from the kernel, and store the 32-bit truncation in the existing 'offset' field, for compatibility.

2013-11-15intel: Add support for GPU reset status query ioctlIan Romanick
I would have just used the drmIoctl interface directly in Mesa, but the ioctl needs some data from the drm_intel_context that is not exposed outside libdrm. This ioctl is in the drm-intel-next tree as b635991. v2: Update based on Mika's kernel work. v3: Fix compile failures from last-minute typos. Sigh. v4: Import the actual changes from the kernel i915_drm.h. Only comments on some fields of drm_i915_reset_stats differed. There are still some deltas between the kernel i915_drm.h and the one in libdrm, but those can be resolved in other patches.

2013-11-08Revert "intel: Add support for GPU reset status query ioctl"Dave Airlie
This reverts commit 6335e1d28c422050024bcf4100c4fb3a5bac2afb. No taxation without representation, in other words no userspace without kernel stuff being in a stable location, either drm-next but I'll accept drm-intel-next for intel specific stuff.

2012-06-27intel: wait render timeout implementationBen Widawsky
int drm_intel_gem_bo_wait(drm_intel_bo *bo, uint64_t timeout_ns) This should bump the libdrm version. We're waiting for context support so we can do both features in one bump. v2: don't return remaining timeout amount use get param and fallback for older kernels v3: only doing getparam at init prototypes now have a signed input value v4: update comments fall back to correct polling behavior with new userspace and old kernel v5: since the drmIoctl patch was not well received, return appropriate values in this function instead. As Daniel pointed out, the polling case (timeout == 0) should also return -ETIME. Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2012-05-10intel: Add the ability to supply annotations for .aub files.Paul Berry
This patch adds a new function, drm_intel_bufmgr_gem_set_aub_annotations(), which can be used to annotate the type and subtype of data stored in various sections of each buffer. This data is used to populate type and subtype fields when generating the .aub file, which improves the ability of later debugging tools to analyze the contents of the .aub file. If drm_intel_bufmgr_gem_set_aub_annotations() is not called, then we fall back to the old set of annotations (annotate the portion of the batchbuffer that is executed as AUB_TRACE_TYPE_BATCH, and everything else as AUB_TRACE_TYPE_NOTYPE).

2012-03-09intel: Add .aub file output support.Eric Anholt
This will allow the driver to capture all of its execution state to a file for later debugging. intel_gpu_dump is limited in that it only captures batchbuffers, and Mesa's captures, while more complete, still capture only a portion of the state involved in execution. This is a squash commit of a long series of hacking as we tried to get the resulting traces to work in the internal simulator.

2011-12-29intel: Get intel_decode.c minimally building.Eric Anholt
My plan is to use this drm_intel_dump_batchbuffer() interface for the current GPU tools, and the current Mesa batch dumping usage, while eventually building more interesting interfaces for other uses. Warnings are currently suppressed by using a helper lib with CFLAGS set manually, because the code is totally not ready for libdrm's warnings setup.

2011-12-05intel: Add an interface to limit vma cachingChris Wilson
There is a per-process limit on the number of vma that the process can keep open, so we cannot keep an unlimited cache of unused vma's (besides keeping track of all those vma in the kernel adds considerable overhead). However, in order to work around inefficiencies in the kernel it is beneficial to reuse the vma, so keep a MRU cache of vma. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-10-28intel: Add an interface for removing relocs after they're added.Eric Anholt
This lets us replace the current inner drawing loop of mesa: for each prim { compute bo list if (check_aperture_space(bo list)) { batch_flush() compute bo list if (check_aperture_space(bo list)) { whine_about_batch_size() fall back; } } upload state to BOs } with this inner loop: for each prim { retry: upload state to BOs if (check_aperture_space(batch)) { if (!retried) { reset_to_last_prim() batch_flush() } else { if (batch_flush()) whine_about_batch_size() goto retry; } } } This avoids having to implement code to walk over certain sets of GL state twice (the "compute bo list" step). While it's not a performance improvement, it's a significant win in code complexity: about -200 lines, and one place to make mistakes related to aperture space instead of N places to forget some BO we should have included. Note how if we do a reset in the new loop , we immediately flush. We don't need to check aperture space -- the kernel will tell us if we actually ran out of aperture or not. And if we did run out of aperture, it's because either the single prim was too big, or because check_aperture was wrong at the point of setting up the last primitive.

This patch to libdrm adds support for the new execbuf2 ioctl. If detected, it will be used instead of the old ioctl. By using the new drm_intel_bufmgr_gem_enable_fenced_relocs(), you can indicate that any time a fence register is actually required for a relocation target you will call drm_intel_bo_emit_reloc_fence instead of drm_intel_bo_emit_reloc, which will reduce fence register pressure.
