drm/vkms: Fix cpu_to_le16()/le16_to_cpu() warnings

2024-08-08T08:04:13Z

Building with Sparse enabled prints this warning for cpu_to_le16() calls: warning: incorrect type in assignment (different base types) expected unsigned short [usertype] got restricted __le16 [usertype] And this warning for le16_to_cpu() calls: warning: cast to restricted __le16 Declare the target buffer as __le16 to fix both warnings.

drm/vkms: Remove event from vkms_output

2024-07-07T18:03:54Z

While working on rvkms, I noticed that there's no code that actually uses the drm_pending_vblank_event that's embedded in vkms_output. So, just drop the member from the struct.

drm/vkms: Use fbdev-shmem

2024-05-02T09:33:22Z

Implement fbdev emulation with fbdev-shmem. Avoids the overhead of fbdev-generic's additional shadow buffering. No functional changes.

drm/vkms: Avoid reading beyond LUT array

2024-01-02T13:06:53Z

When the floor LUT index (drm_fixp2int(lut_index) is the last index of the array the ceil LUT index will point to an entry beyond the array. Make sure we guard against it and use the value of the floor LUT index. v3: - Drop bits from commit description that didn't contribute anything of value Fixes: db1f254f2cfa ("drm/vkms: Add support to 1D gamma LUT") Signed-off-by: Harry Wentland Cc: Arthur Grillo Reviewed-by: Arthur Grillo Reviewed-by: Melissa Wen Signed-off-by: Melissa Wen Link: https://patchwork.freedesktop.org/patch/msgid/20231108163647.106853-6-harry.wentland@amd.com

drm/vkms: move wb's atomic_check from encoder to connector

2023-12-08T09:24:30Z

As the renamed drm_atomic_helper_check_wb_connector_state() now accepts drm_writeback_connector as the first argument (instead of drm_encoder), move the VKMS writeback atomic_check from drm_encoder_helper_funcs to drm_connector_helper_funcs. Also drop the vkms_wb_encoder_helper_funcs, which have become empty now.

drm/atomic-helper: rename drm_atomic_helper_check_wb_encoder_state

2023-12-08T09:24:27Z

The drm_atomic_helper_check_wb_encoder_state() function doesn't use encoder for anything other than getting the drm_device instance. The function's description talks about checking the writeback connector state, not the encoder state. Moreover, there is no such thing as an encoder state, encoders generally do not have a state on their own. Rename the function to drm_atomic_helper_check_wb_connector_state() and change arguments to drm_writeback_connector and drm_atomic_state.

Revert "drm/vkms: Fix race-condition between the hrtimer and the atomic commit"

2023-09-14T10:48:19Z

This reverts commit a0e6a017ab56936c0405fe914a793b241ed25ee0. Unlocking a mutex in the context of a hrtimer callback is violating mutex locking rules, as mutex_unlock() from interrupt context is not permitted.
