2019-03-11i915/gem_ppgtt: Estimate resource usage and bail if it means swapping!Chris Wilson
fi-kbl-guc's swap ran dry while running blt-vs-render-ctxN, which is mildly concerning but conceivable as we never checked there was enough memory to run the test to begin with. Each child needs to keep its own surface and possible a pair of logical contexts (one for rcs and one for bcs) so check that there is enough memory to allow all children to co-exist. During execution, we require another surface and batch, but these are temporary and so should fit fine with a small amount of thrashing on the boundary.

2019-03-06i915/gem_exec_parse: Switch to a fixed timeout for basic-allocationsChris Wilson
basic-allocations was written to demonstrate a flaw in our continual reallocation of cmdparser shadow bo, largely fixed by keeping a small cache of bo of different lengths (to speed up the search for the correct sized bo). We only care enough to exercise the slowdown by submitting lots of execbufs, and can see the effect of bo caching on the rate, so replace the fixed number of iterations with a timeout and count how many batches we could submit instead. Similarly, we now do not need to wait for all of our queue to complete as we can tell the kernel to drop the queue instead.

2019-03-05gem_ctx_isolation.c - Gen11 enabling for context isolation testDale B Stimson
This patch is a change to igt file tests/i915/gem_ctx_isolation.c to add and enable Gen11 support. This patch accounts for whitelisted registers appropriately for the different Gen levels. This patch accounts for the changed MMIO offsets of Gen11. This patch redefines MAX_REG from 0x40000 to 0x200000 due to the larger total register space for Gen11 mmio offsets. A current Gen11 SKU has two video engines (with indexes 0 and 2, for VCS0 and VCS2), with VCS1 not being used. Current kernel and igt limitations only allow for VCS0 and VCS1. Those limitations are in the process of being removed. See for example the RFC/PATCH series on igt-dev from Andy Shyti: [igt-dev] [RFC PATCH v9 0/5] new engine discovery interface which depends on in-process kernel "media scalability" patches. Lacking the above infrastructure at the moment: The array of registers to be tested includes VCS2 and VCS3 registers. They are present as a provision for the future, but they will not actually be tested as those engines are not yet known to the underlying infrastructure. When run on Gen11 this patch skips the sub-tests for the non-existent VCS1 with these warnings: Test requirement not met in function gem_require_engine, file ../lib/igt_gt.h:114: Test requirement: gem_has_engine(gem_fd, class, instance) Signed-off-by: Dale B Stimson <dale.b.stimson@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
