This is presently unused on HW, we read a bunch of regs and calculate the watermark during the second supervisor interrupt.

2023-09-19drm/nouveau/kms: Add INHERIT ioctl to nvkm/nvif for reading IOR stateLyude Paul8-13/+291
Now that we're supporting things like Ada and the GSP, there's situations where we really need to actually know the display state that we're starting with when loading the driver in order to prevent breaking GSP expectations. The first step in doing this is making it so that we can read the current state of IORs from nvkm in DRM, so that we can fill in said into into the atomic state. We do this by introducing an INHERIT ioctl to nvkm/nvif. This is basically another form of ACQUIRE, except that it will only acquire the given output path for userspace if it's already set up in hardware. This way, we can go through and probe each outp object we have in DRM in order to figure out the current hardware state of each one. If the outp isn't in use, it simply returns -ENODEV. This is also part of the work that will be required for implementing GSP support for display. While the GSP should mostly work without this commit, this commit should fix some edge case bugs that can occur on initial driver load. This also paves the way for some of the initial groundwork for fastboot support.

2023-09-18drm/i915/cx0: Add step for programming msgbus timerGustavo Sousa2-48/+41
There was a recent update in the BSpec adding an extra step to the PLL enable sequence, which is for programming the msgbus timer. Since we also touch PHY registers during hw readout, let's do the programming when starting a transaction rather than only when doing the PLL enable sequence. This might be the missing step that was causing the timeouts that we have recently seen during C20 SRAM register programming sequences. With this in place, we shouldn't need the logic to bump the timer thresholds, since now we have a documented value that should be set peform programming the registers. As such, let's also remove intel_cx0_bus_check_and_bump_timer(), but keep the part that checks if hardware really detected a timeout, which might be useful debugging information. v2: - Use debug level instead of warning for the message notifying that the hardware did not detect the timeout. (Mika) - Got a new BSpec update clarifying that we need to program the msgbus timer of both PHY lanes. Update the changes to reflect that.

2023-09-18drm/i915: Remove runtime suspended boolean from intel_runtime_pm structJouni Högander5-8/+4
It's not necessary to carry separate suspended status information in intel_runtime_pm struct as this information is already in underlying device structure. Remove it and use pm_runtime_suspended() to obtain suspended status information when needed.
