2021-04-07drm/msm/disp/dpu1: turn off vblank irqs aggressively in dpu driverKalyan Thota8-0/+155
Set the flag vblank_disable_immediate = true to turn off vblank irqs immediately as soon as drm_vblank_put is requested so that there are no irqs triggered during idle state. This will reduce cpu wakeups and help in power saving. To enable vblank_disable_immediate flag the underlying KMS driver needs to support high precision vblank timestamping and also a reliable way of providing vblank counter which is incrementing at the leading edge of vblank. This patch also brings in changes to support vblank_disable_immediate requirement in dpu driver. Changes in v1: - Specify reason to add vblank timestamp support. (Rob). - Add changes to provide vblank counter from dpu driver. Changes in v2: - Fix warn stack reported by Rob Clark with v2 patch. Changes in v3: - Move back to HW frame counter (Rob). Changes in v4: - Frame count mismatch was causing a DRM WARN stack spew. DPU HW will increment the frame count at the end of the sync, where as vblank will be triggered at the fetch_start counter which is calculated as v_total - vfp. This is to start fetching early for panels with low vbp w.r.t hw latency lines. Add logic to detect the line count if it falls between vactive and v_total then return incremented frame count value.

2021-04-07drm/msm: Fix debugfs deadlockRob Clark5-15/+35
In normal cases the gem obj lock is acquired first before mm_lock. The exception is iterating the various object lists. In the shrinker path, deadlock is avoided by using msm_gem_trylock() and skipping over objects that cannot be locked. But for debugfs the straightforward thing is to split things out into a separate list of all objects protected by it's own lock.

When the system is under heavy memory pressure, we can end up with lots of concurrent calls into the shrinker. Keeping a running tab on what we can shrink avoids grabbing a lock in shrinker->count(), and avoids shrinker->scan() getting called when not profitable. Also, we can keep purged objects in their own list to avoid re-traversing them to help cut down time in the critical section further.

2021-04-07platform/surface: aggregator_registry: Give devices time to set up when connectingMaximilian Luz1-58/+40
Sometimes, the "base connected" event that we rely on to (re-)attach the device connected to the base is sent a bit too early. When this happens, some devices may not be completely ready yet. Specifically, the battery has been observed to report zero-values for things like full charge capacity, which, however, is only loaded once when the driver for that device probes. This can thus result in battery readings being unavailable. As we cannot easily and reliably discern between devices that are not ready yet and devices that are not connected (i.e. will never be ready), delay adding these devices. This should give them enough time to set up. The delay is set to 2.5 seconds, which should give us a good safety margin based on testing and still be fairly responsive for users. To achieve that delay switch to updating via a delayed work struct, which means that we can also get rid of some locking.

2021-04-07cpuidle: menu: Take negative "sleep length" values into accountRafael J. Wysocki1-6/+11
Make the menu governor check the tick_nohz_get_next_hrtimer() return value so as to avoid dealing with negative "sleep length" values and make it use that value directly when the tick is stopped. While at it, rename local variable delta_next in menu_select() to delta_tick which better reflects its purpose. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2021-04-07cpuidle: teo: Take negative "sleep length" values into accountRafael J. Wysocki1-7/+15
Modify the TEO governor to take possible negative return values of tick_nohz_get_next_hrtimer() into account by changing the data type of some variables used by it to s64 which allows it to carry out computations without potentially problematic data type conversions into u64. Also change the computations in teo_select() so that the negative values themselves are handled in a natural way to avoid adding extra negative value checks to that function. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2021-04-07cpuidle: teo: Adjust handling of very short idle timesRafael J. Wysocki1-16/+14
If the time till the next timer event is shorter than the target residency of the first idle state (state 0), the TEO governor does not update its metrics for any idle states, but arguably it should record a "hit" for idle state 0 in that case, so modify it to do that. Accordingly, also make it record an "early hit" for idle state 0 if the measured idle duration is less than its target residency, which allows one branch more to be dropped from teo_update().

2021-04-07cpuidle: Use s64 as exit_latency_ns and target_residency_ns data typeRafael J. Wysocki1-0/+4
Subsequent changes will cause the exit_latency_ns and target_residency_ns fields in struct cpuidle_state to be used in computations in which data type conversions to u64 may turn a negative number close to zero into a verly large positive number leading to incorrect results. In preparation for that, change the data type of the fields mentioned above to s64, but ensure that they will not be negative themselves. No intentional functional impact. Signed-off-by: Rafael J.
