drm/i915/dp: Assume panel power is off if runtime suspended

2024-10-11T11:55:01+00:00

If the device is runtime suspended the eDP panel power is also off. Ignore a short HPD on eDP if the device is suspended accordingly, instead of checking the panel power state via the PPS registers for the same purpose. The latter involves runtime resuming the device unnecessarily, in a frequent scenario where the panel generates a spurious short HPD after disabling the panel power and the device is runtime suspended.

drm/i915: use NULL for zero wakeref_t instead of plain integer 0

2024-10-04T07:29:24+00:00

As of commit 2edc6a75f26c ("drm/i915: switch intel_wakeref_t underlying type to struct ref_tracker *") we gained quite a few sparse warnings about "Using plain integer as NULL pointer" for using 0 to initialize wakeref_t.

This information is used in many places and it doesn't have anything to do with runtime_pm directly. Let's move it to the driver, where it belongs.

UAPI Changes: - drm/i915: Implement fdinfo memory stats printing Use the newly added drm_print_memory_stats helper to show memory utilisation of our objects in drm/driver specific fdinfo output. To collect the stats we walk the per memory regions object lists and accumulate object size into the respective drm_memory_stats categories.

drm/i915: Replace custom intel runtime_pm tracker with ref_tracker library

2023-11-20T11:36:54+00:00

Beside reusing existing code, the main advantage of ref_tracker is tracking per instance of wakeref. It allows also to catch double put. On the other side we lose information about the first acquire and the last release, but the advantages outweigh it.

It's not necessary to carry separate suspended status information in intel_runtime_pm struct as this information is already in underlying device structure.
