Chris Wilson cc4f8fc72e drm/i915/pmu: Reconstruct active state on starting busy-stats ... We have a hole in our busy-stat accounting if the pmu is enabled during a long running batch, the pmu will not start accumulating busy-time until the next context switch. This then fails tests that are only sampling a single batch. v2: Count each active port just once (context in/out events are only on the first and last assignment to a port). v3: Avoid hardcoding knowledge of 2 submission ports Fixes: 30e17b7847 ("drm/i915: Engine busy time tracking") Testcase: igt/perf_pmu/busy-start Testcase: igt/perf_pmu/busy-double-start Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180111073031.14614-1-chris@chris-wilson.co.uk (cherry picked from commit 4900727d35) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>		2018-02-01 07:31:42 -08:00
