2021-07-28drm/vmwgfx: Be a lot more flexible with MOB limitsZack Rusin
The code was trying to keep a strict limit on the amount of mob memory that was used in the guest by making it match the host settings. There's technically no reason to do that (guests can certainly use more than the host can have resident in renderers at the same time). In particular this is problematic because our userspace is not great at handling OOM conditions and running out of MOB space results in GL apps crashing, e.g. gnome-shell likes to allocate huge surfaces (~61MB for the desktop on 2560x1600 with two workspaces) and running out of memory there means that the gnome-shell crashes on startup taking us back to the login and resulting in a system where one can not login in graphically anymore. Instead of letting the userspace crash we can extend available MOB space, we just don't want to use all of the RAM for graphics, so we're going to limit it to half of RAM. With the addition of some extra logging this should make the "guest has been configured with not enough graphics memory" errors a lot easier to diagnose in cases where the automatic expansion of MOB space fails.

2021-07-28drm/vmwgfx: Cleanup loggingZack Rusin
The code was using the old DRM logging functions, which made it hard to figure out what was coming from vmwgfx. The newer logging helpers include the driver name in the logs and make it explicit which driver they're coming from. This allows us to standardize our logging a bit and clean it up in the process. vmwgfx is a little special because technically the hardware it's running on can be anything from the last 12 years or so which is why we need to include capabilities in the logs in the first place or otherwise we'd have no way of knowing what were the capabilities of the platform the guest was running in.

2021-07-28drm/i915: dgfx cards need to wait on pcode's uncore init doneBadal Nilawar
In discrete cards, the graphics driver shouldn't proceed with the probe or resume unless PCODE indicated everything is done, including memory training and gt bring up. For this reason, the driver probe and resume paths needs to be blocked until PCODE indicates it is done. Also, it needs to aborted if the notification never arrives. In general, the few miliseconds would be enough and the regular PCODE recommendation for the timeout was 10 seconds. However there are some rare cases where this initialization can take up to 1 minute. So, PCODE has increased the recommendation to 3 minutes so we don't fully block the device utilization when something just got delayed for whatever reason. To be on the safest side, let's accept this recommendation, since on the regular case it won't delay or block the driver initialization and resume flows Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Badal Nilawar <badal.nilawar@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210727173338.901264-1-badal.nilawar@intel.com

2021-07-28drm/msm: Conversion to drm schedulerRob Clark
For existing adrenos, there is one or more ringbuffer, depending on whether preemption is supported. When preemption is supported, each ringbuffer has it's own priority. A submitqueue (which maps to a gl context or vk queue in userspace) is mapped to a specific ring- buffer at creation time, based on the submitqueue's priority. Each ringbuffer has it's own drm_gpu_scheduler. Each submitqueue maps to a drm_sched_entity. And each submit maps to a drm_sched_job.

2021-07-28drm/i915: Extract i915_module.cDaniel Vetter
The module init code is somewhat misplaced in i915_pci.c, since it needs to pull in init/exit functions from every part of the driver and pollutes the include list a lot. Extract an i915_module.c file which pulls all the bits together, and allows us to massively trim the include list of i915_pci.c. The downside is that have to drop the error path check Jason added to catch when we set up the pci driver too early. I think that risk is acceptable for this pretty nice include.

During a rebase the parameters were partially renamed, but not completely. Since the subsequent patches that start using this macro haven't landed on an upstream tree yet this didn't cause a build failure.

2021-07-28drm/i915/adlp: Add workaround to disable CMTG clock gatingImre Deak
The driver doesn't depend atm on the common mode timing generator functionality (it would be used for some power saving feature and panel timing synchronization), however DMC will corrupt the CMTG registers across DC5 entry/exit sequences unless the CMTG clock gating is disabled. This in turn can lead to at least the DPLL0/1 configuration getting stuck at their last state, which means we can't reprogram them to a new config. Add the corresponding Bspec workaround to prevent the above. v2: Fix checkpatch errors.

2021-07-27drm/i915/adl_p: Allow underrun recovery when possibleMatt Roper
ADL_P requires that we disable underrun recovery when downscaling (or using the scaler for YUV420 pipe output), using DSC, or using PSR2. Otherwise we should be able to enable the underrun recovery. On DG2 we need to keep underrun recovery disabled at all times, but the chicken bit in PIPE_CHICKEN has an inverted meaning (it's an enable bit instead of disable). v2: - Reverse the condition (clear the disable bit when supported, set disable bit when not supported).

2021-07-27drm/msm: Track "seqno" fences by idrRob Clark
Previously the (non-fd) fence returned from submit ioctl was a raw seqno, which is scoped to the ring. But from UABI standpoint, the ioctls related to seqno fences all specify a submitqueue. We can take advantage of that to replace the seqno fences with a cyclic idr handle. This is in preperation for moving to drm scheduler, at which point the submit ioctl will return after queuing the submit job to the scheduler, but before the submit is written into the ring (and therefore before a ring seqno has been assigned). Which means we need to replace the dma_fence that userspace may need to wait on with a scheduler fence.

2021-07-27drm/msm: Consolidate submit bo stateRob Clark
Move all the locked/active/pinned state handling to msm_gem_submit.c. In particular, for drm/scheduler, we'll need to do all this before pushing the submit job to the scheduler. But while we're at it we can get rid of the dupicate pin and refcnt.
