* intel/isl: Tighten up restrictions for CCS on gen7Jason Ekstrand2017-07-221-7/+23
| | | | | | | | | | It may technically be possible to enable some sort of fast-clear support for at least the base slice of a 2D array texture on gen7. However, it's not documented to work, we've never tried to do it in GL, and we have no idea what the hardware does if you turn on CCS_D with arrayed rendering. Let's just play it safe and disallow it for now. If someone really cares that much about gen7 performance, they can come along and try to get it working later.

* i965: Drop non-LLC lunacy in the program cache code.Kenneth Graunke2017-07-223-70/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The non-LLC story was a horror show. We uploaded data via pwrite (drm_intel_bo_subdata), which would stall if the cache BO was in use (being read) by the GPU. Obviously, we wanted to avoid that. So, we tried to detect whether the buffer was busy, and if so, we'd allocate a new BO, map the old one read-only (hopefully not stalling), copy all shaders compiled since the dawn of time to the new buffer, upload our new one, toss the old BO, and let the state upload code know that our program cache BO changed. This was a lot of extra data copying, and flagging BRW_NEW_PROGRAM_CACHE would also cause a new STATE_BASE_ADDRESS to be emitted, stalling the entire pipeline. Not only that, but our rudimentary busy tracking consistented of a flag set at execbuf time, and not cleared until we threw out the program cache BO. So, the first shader upload after any drawing would hit this "abandon the cache and start over" copying path. This is largely unnecessary - it's just ancient and crufty code. We can use the same persistent mapping paths on all platforms. On non-ancient kernels, this will use a write combining map, which should be reasonably fast. One aspect that is worse: we do occasionally grow the program cache BO, and copy the old contents to the newer BO. This will suffer from UC readback performance now. To mitigate this, we use the MOVNTDQA based streaming memcpy on platforms with SSE 4.1 (all Gen7+ atoms). Gen4-5 are unfortunately going to be penalized. v2: Add MOVNTDQA path, rebase on other map flag changes. v3: Drop cache->bo_used_by_gpu too (caught by Chris Wilson).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Write-combine mappings give much better performance on writes than uncached access through the GTT. Improves performance of GFXBench 4's gl_driver2 benchmark at 1024x768 on Apollolake by 3.6086% +/- 0.674193% (n=15). v2: (by Ken) Rebase on lockless mappings, map_count deletion, valgrind updates, potential for CPU/WC maps failing, and other changes. v3: (by Ken and Chris Wilson) (Ken): Rebase on set_domain -> gem_wait (Chris): Fix up a failed CPU/WC mmaping with a GTT mapping Not all objects will be mappable for direct access by the CPU (either using WC/CPU or WC paths), for example, a dmabuf wrapping an object on a foreign device or an object wrapping access to stolen memory. Since either the physical pages are not known or even do not exist, we need to use the mediated, indirect access via the GTT. (If one day, the kernel does suddenly start providing mediated access via a regular WB/WC mmapping, we no longer need the fallback.) v4: Avoid falling back for MAP_RAW (Chris).

* i965/bufmgr: Skip wait ioctl when not busy.Kenneth Graunke2017-07-221-0/+4
| | | | | | | | If the buffer is idle, we I915_GEM_WAIT will return immediately, so we may as well skip the ioctl altogether. We can't trust the "idle" flag for external buffers, but for most, it should be fine. Reviewed-by: Matt Turner <[email protected]>
* i965/bufmgr: Explicitly wait instead of using I915_GEM_SET_DOMAIN.Kenneth Graunke2017-07-221-17/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the advent of asynchronous maps, domain tracking doesn't make a whole lot of sense. Buffers can be in use on both the CPU and GPU at the same time. In order to avoid blocking, we stopped using set_domain for asynchronous mappings, which means that the kernel's tracking has lies. We can't properly track it in userspace either, as the kernel can change domains on us spontaneously (for example, when un-swapping). According to Chris Wilson, I915_GEM_SET_DOMAIN does the following: 1. pins the backing storage (acquiring pages outside of the struct_mutex) 2. waits either for read/write access, including inter-device waits 3. updates the domain, clflushing as required 4. marks the object as used (for swapping) 5. turns off FBC/PSR/fancy scanout caching Item (1) is not terribly important. Most BOs are recycled via the BO cache, so they already have pages. Regardless, we fixed this via an initial set_domain in the previous patch. We implement item (2) with I915_GEM_WAIT. This has one downside: we'll stall unnecessarily if we do a read-only mapping of a buffer that the GPU is reading. I believe this is pretty uncommon. We may want to extend the wait ioctl at some point. Mesa already does item (3) itself. For cache-coherent buffers (most on LLC systems), we don't need to do any clflushing - the CPU and GPU views are coherent. For non-coherent buffers (most on non-LLC systems), we currently only use the CPU for read-only maps, and we explicitly clflush when necessary. We don't care about item (4)...swapping has already killed performance. Plus, with async maps, the kernel's domain tracking is already bogus, so it can't do this accurately regardless. Item (5) should be okay because we avoid cached maps of scanout buffers. Reviewed-by: Matt Turner <[email protected]>
