2019-08-10drm/i915: buddy allocatorMatthew Auld
Simple buddy allocator. We want to allocate properly aligned power-of-two blocks to promote usage of huge-pages for the GTT, so 64K, 2M and possibly even 1G. While we do support allocating stuff at a specific offset, it is more intended for preallocating portions of the address space, say for an initial framebuffer, for other uses drm_mm is probably a much better fit. Anyway, hopefully this can all be thrown away if we eventually move to having the core MM manage device memory.

2019-08-10drm/i915/gtt: disable 2M pages for pre-gen11Matthew Auld
We currently disable THP(Transparent-Huge-Pages) for our shmem objects due to a performance regression with read BW in some internal benchmarks. Given that this is our main source of 2M pages, there really isn't much point in enabling 2M GTT pages, especially as that comes at the cost of disabling the GTT cache. However from gen11 it looks like we should hopefully see the HW issue resolved. Given this opt for only enabling 2M GTT pages from gen11 onwards.

2019-08-09drm/i915: split out uncore_mmio_debugDaniele Ceraolo Spurio
Multiple uncore structures will share the debug infrastructure, so move it to a common place and add extra locking around it. Also, since we now have a separate object, it is cleaner to have dedicated functions working on the object to stop and restart the mmio debug. Apart from the cosmetic changes, this patch introduces 2 functional updates: - All calls to check_for_unclaimed_mmio will now return false when the debug is suspended, not just the ones that are active only when i915_modparams.mmio_debug is set. If we don't trust the result of the check while a user is doing mmio access then we shouldn't attempt the check anywhere. - i915_modparams.mmio_debug is not save/restored anymore around user access. The value is now never touched by the kernel while debug is disabled so no need for save/restore. v2: squash mmio_debug patches, restrict mmio_debug lock usage (Chris) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190809063116.7527-1-chris@chris-wilson.co.uk

Since we have already stopped the ring, cleared the ring, disabled the ring (and verifying the ring is clear), a later debug message that the ring is no longer clear serves no function. It appears it restarts anyway, and we verify that the ring started correctly afterwards.

2019-08-09drm/i915: Generalise BSD default selectionChris Wilson
For the default I915_EXEC_BSD round robin selector, it may select any available VCS engine. Make it so.

2019-08-09drm/i915: Replace global bsd_dispatch_index with random seedChris Wilson
We keep a global seed for the legacy BSD round-robin selector, but in our testing of multiple simultaneous client workloads, a random seed spreads the load more evenly. (As even as an initial round-robin selector can be!) Removing the global is one less variable we have to find a home for! We can simulate multi-client (both same and mixed workloads) using igt/gem_wsim to work out optimal strategies and then compare our simulation with the actual transcoder on multi-engine machines. This fixed round-robin turns out to be one of the worst methods. No user is advised to use this method; the current suggestion is to use a virtual engine for agnostic batches, randomised submission or using the busyness tracking to select the most idle engine at the time of dispatch. At the present time, intel-media is explicit, but libva still seems to use it, with the exception of batches that must execute on vcs0. Oh well.

2019-08-09drm/i915: Check for a second VCS engine more carefullyChris Wilson
To use the legacy BSD selector, you must have a second VCS engine, or else the ABI simply maps the request for another engine onto VCS0. However, we only checked a single VCS1 location and overlooking the possibility of a sparse VCS set being mapped to the dense ABI. v2: num_vcs_engines() turns out to be reusable and futureproof it so we never have to worry about this silly bit of ABI again!
