Re: [Intel-gfx] [PATCH v9 5/7] vfio: Define vfio based dma-buf operations

Hi: Thanks for the discussions! If the userspace application has already maintained a LRU list, it looks like we don't need generation anymore, as userspace application will lookup the guest framebuffer from the LRU list by "offset". No matter how, it would know if this is a new guest

[Intel-gfx] [PATCH 2nd resend 4/4] drm/i915: Acquire PUNIT->PMIC bus for intel_uncore_forcewake_reset()

intel_uncore_forcewake_reset() does forcewake puts and gets as such we need to make sure that no-one tries to access the PUNIT->PMIC bus (on systems where this bus is shared) while it runs, otherwise bad things happen. Normally this is taken care of by the i915_pmic_bus_access_notifier() which

[Intel-gfx] [PATCH 2nd resend 2/4] drm/i915: Re-register PMIC bus access notifier on runtime resume

intel_uncore_suspend() unregisters the uncore code's PMIC bus access notifier and gets called on both normal and runtime suspend. intel_uncore_resume_early() re-registers the notifier, but only on normal resume. Add a new intel_uncore_runtime_resume() function which only re-registers the notifier

[Intel-gfx] [PATCH 2nd resend 1/4] drm/i915: Fix false-positive assert_rpm_wakelock_held in i915_pmic_bus_access_notifier

assert_rpm_wakelock_held is triggered from i915_pmic_bus_access_notifier even though it gets unregistered on (runtime) suspend, this is caused by a race happening under the following circumstances: intel_runtime_pm_put does: atomic_dec(_priv->pm.wakeref_count);

[Intel-gfx] [PATCH 2nd resend 3/4] drm/i915: Call uncore_suspend before platform suspend handlers

Quoting Ville: "the forcewake timer might still be active until the uncore suspend, and having active forcewakes while we've already told the GT wake stuff to stop acting normally doesn't seem quite right to me." Reported-by: Ville Syrjälä Suggested-by: Imre Deak

[Intel-gfx] [PATCH] drm/i915: Print pwm device-name when using pwm for backlight control

On Bay Trail devices either the Crystal Cove PMIC's pwm or the LPSS' pwm is used to control the backlight. Other drivers take core of providing a backlight_pwm alias through pwm_add_table, but it is still useful to know which pwm device actually ends up being used for debugging backlight issues,
