      lib/psr: Add support for toggling edp psr through debugfs, v5. · 8f89a00c
      Maarten Lankhorst authored
      It's harmful to write to enable_psr at runtime, and the patch that allows
      us to change i915_edp_psr_debug with the panel running will require us
      to abandon the module parameter. Hence the userspace change needs to be
      put in IGT first before we can change it at kernel time.
      Toggling it to debugfs will mean we can skip a modeset when changing our
      feature set.
      Changes since v1:
      - Rebase with the previous patches dropped.
      Changes since v2:
      - Rebase on top of new api in i915_edp_psr_debug.
      Changes since v3:
      - Enable IRQ debugging for extra logging.
      - Force PSR1 mode. (dhnkrn)
      - Move PSR enable/disable functions to lib/igt_psr. (dhnkrn)
      Changes since v4:
      - Redisable irqs right away when debugfs api doesn't work. (dhnkrn)
      - Use hex everywhere. (dhnkrn)

      tests/perf_pmu: Handle CPU hotplug failures better · ec872b7d
      Chris Wilson authored
      CPU hotplug, especially CPU0, can be flaky on commodity hardware.
      To improve test reliability and reponse times when testing larger runs we
      need to handle those cases better.
      Handle failures to off-line a CPU by immediately skipping the test, and
      failures to on-line a CPU by immediately rebooting the machine.
      This patch includes igt_sysrq_reboot implementation from Chris Wilson.
      v2: Halt by default, reboot if env variable IGT_REBOOT_ON_FATAL_ERROR is
          set. (Petri Latvala)
      v3: Add missign docs and update stale comment. (Petri Latvala)
      v4: Use pause instead of sleep. (Chris Wilson)
      v5: Newlines! (Chris Wilson)
