As described in the previous patch a connector shouldn't change its status while it's forced to a connected/disconnected state. This can still happen while running the connector detect function to account for lost HPD events in a low-power state.

DRM display connectors forced to a connected/disconnected state via the drm_connector::force member shouldn't change their status. Atm, this can still happen in the connector's detect function when called to handle a hotplug event. This in turn may lead to the GETCONNECTOR ioctl to report the incorrect state if it's called to return the connector properties without doing an actual detection (by calling the ioctl with a non-zero drm_mode_get_connector::count_modes). Fix the above by updating the connector state during hotplug detect only if the connector state is not forced.

2023-08-11drm/i915: Avoid endless HPD poll detect loop via runtime suspend/resumeImre Deak4-19/+21
The issue fixed in commit a8ddac7c9f06 ("drm/i915: Avoid HPD poll detect triggering a new detect cycle") on VLV, CHV is still present on platforms where the display hotplug detection functionality is available whenever the device is in D0 state (hence these platforms switch to HPD polling only when the device is runtime suspended). The above commit avoids an endless i915_hpd_poll_init_work() -> connector detect loop by making sure that by the end of i915_hpd_poll_init_work() all display power references acquired by the connector detect functions which can trigger a new cycle (display core power domain) are dropped. However on platforms where HPD polling is enabled/disabled only from the runtime suspend/resume handlers, this is not ensured: for instance eDP VDD, TypeC port PHYs and the runtime autosuspend delay may still keep the device runtime resumed (via a power reference acquired during connector detection and hence result in an endless loop like the above). Solve the problem described in the above commit on all platforms, by making sure that a i915_hpd_poll_init_work() -> connector detect sequence can't take any power reference in the first place which would trigger a new cycle, instead of relying on these power references to be dropped by the end of the sequence. With the default runtime autosuspend delay (10 sec) this issue didn't happen in practice, since the device remained runtime resumed for the whole duration of the above sequence. CI/IGT tests however set the autosuspend delay to 0, which makes the problem visible, see References: below. Tested on GLK, CHV. v2: Don't warn about a requeued work, to account for disabling polling directly during driver loading, reset and system resume.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void.

2023-08-10drm/i915/irq: move all PCH irq postinstall calls to display codeJani Nikula3-17/+12
Unify on making the calls from display code. Need to add an if ladder in gen8_de_irq_postinstall() for now, but the function looks like it could be overall be better split by platform. Something for the future. The display version check for mtp seems a bit suspect, but this matches current code.

2023-08-10drm/i915/gt: Apply workaround 22016122933 correctlyJonathan Cavitt6-16/+17
WA_22016122933 was recently applied to all MeteorLake engines, which is simultaneously too broad (should only apply to Media engines) and too specific (should apply to all platforms that use the same media engine as MeteorLake). Correct this in cases where coherency settings are modified. There were also two additional places where the workaround was applied unconditionally. The change was confirmed as necessary for all platforms, so the workaround label was removed.

Refactor i915_coherent_map_type to be GT-centric rather than device-centric. Each GT may require different coherency handling due to hardware workarounds. Since the function now takes a GT instead of the i915, the function is renamed and moved to the gt folder.

The object pin created for shmem_create_from_object is just a single use mapping with the sole purpose of reading the contents of the whole object in bulk. And the whole source object is also even a throw-away. Ergo, the additional logic required by i915_coherent_map_type can be safely dropped and simplified.

2023-08-10drm/i915: fix display probe for IVB Q and IVB D GT2 serverJani Nikula1-3/+21
The current display probe is unable to differentiate between IVB Q and IVB D GT2 server, as they both have the same device id, but different subvendor and subdevice. This leads to the latter being misidentified as the former, and should just end up not having a display. However, the no display case returns a NULL as the display device info, and promptly oopses. As the IVB Q case is rare, and we're anyway moving towards GMD ID, handle the identification requiring subvendor and subdevice as a special case first, instead of unnecessarily growing the intel_display_ids[] array with subvendor and subdevice.
