Atm, we don't disable RPS interrupts and related work items before resetting the GPU. This may interfere with the following GPU initialization and cause RPS interrupts to show up in PM_IIR too early before calling gen6_enable_rps_interrupts() (triggering a WARN there). Solve this by disabling RPS interrupts and flushing any related work items before resetting the GPU. v2: - split out the common parts of the gt suspend and the new gt reset functions (Paulo) v3: - remove the check for UMS, it's a NOP nowadays (Daniel) Reported-by: He, Shuang <shuang.he@intel.com> Testcase: igt/gem_reset_stats/ban-render Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=86644 Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> |
