After commit f651c8b05542 ("drm/virtio: factor out the sg_table from virtio_gpu_object"), virtio_gpu_create_object allocates too small space to fit everything in. It is because it allocates struct virtio_gpu_object, but should allocate a newly added struct virtio_gpu_object_shmem which has 2 more members.

[Why] A "dcn20_program_front_end_for_ctx" warning is observed on Renoir. Since the resource definition doesn't explicitly disable triplebuffer flips like Navi10 DC actually attempts to go and setup triplebuffering even when we pass in false to the plane state. If we hit a full update after triplebuffering has been setup we see the assertion since we don't expect full updates while performing triplebuffer flips. Normally this would get reset back to false whne we pass in the new plane state, but since we never actually copy the flag when doing surface updates this doesn't happen.

2020-03-18drm: Skip drm_mode_config_validate() for !modesetVille Syrjälä1-0/+3
drm_mode_config_init() may not have been called when the driver/device doesn't support modeset. That will cause drm_mode_config_validate() to oops. Skip the validation for !modeset. TODO: We may want to consider calling drm_mode_config_init() unconditionally to avoid similar issues elsewhere...

2020-03-18drm: convert .debugfs_init() hook to return void.Wambui Karuga39-118/+58
As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

2020-03-18drm: Validate encoder->possible_clonesVille Syrjälä2-0/+42
Many drivers are populating encoder->possible_clones wrong. Let's persuade them to get it right by adding some loud WARNs. We'll cross check the bits between any two encoders. So either both encoders can clone with the other, or neither can. We'll also complain about effectively empty possible_clones, and possible_clones containing bits for encoders that don't exist. v2: encoder->possible_clones now includes the encoder itelf v3: Move to drm_mode_config_validate() (Daniel) Document that you get a WARN when this is wrong (Daniel) Extract full_encoder_mask() v4: !! instead of !

2020-03-18drm/gma500: Sanitize possible_clonesVille Syrjälä2-10/+10
I doubt the DP+DP and SDVO+SDVO cloning works for this driver. i915 at least doesn't do those. Truthfully there could be some very specific circumstances where some of them would do doable, but genereally it's too much pain to deal with so we've chose not to bother. Let's use the same approach for gma500. Also the LVDS+LVDS and DSI+DSI cases probably don't really exist as there is one of each at most. This does mean we'll now leave possible_clones at 0 for these encoder types whereas previosuly we included the encoder itself in the bitmask. But that's fine as the core now treaks 0 as a special case and adds the encoder itself into the final bitmask reported to userspace.
