The driver is using msleep() if it is safe to use based on in_atomic(). This is not needed this macro is only used from i2c_algorithm::master_xfer() which is always invoked from preemptible context. Remove in_atomic() because it is superfluous. Remove wait_for_atomic() because it has no users. Signed-off-by:

Vmap operations may acquire the dmabuf reservation lock, which is not allowed within atomic commit-tail functions. Therefore move vmap and vunmap from the damage handler into prepare_fb and cleanup_fb callbacks. The mapping is provided as GEM shadow-buffered plane. The functions in the commit tail use the pre-established mapping for damage handling. Signed-off-by:

Several drivers use GEM buffer objects as shadow buffers for the actual framebuffer memory. Right now, drivers do these vmap operations in their commit tail, which is actually not allowed by the locking rules for the dma-buf reservation lock. The involved BO has to be vmapped in the plane's prepare_fb callback and vunmapped in cleanup_fb. This patch introduces atomic helpers for such shadow planes. Plane functions manage the plane state for shadow planes. The provided implementations for prepare_fb and cleanup_fb vmap and vunmap all BOs of struct drm_plane_state.fb. The mappings are afterwards available in the plane's commit-tail functions. For now, all rsp drivers use the simple KMS helpers, so we add the plane callbacks and wrappers for simple KMS. The internal plane functions can later be exported as needed. v3: * documentation fixes v2: * make duplicate_state interface compatible with struct drm_plane_funcs Signed-off-by:

This patch adapts the panfrost pre-defined thresholds change [0] to the lima driver to improve real-world performance. The upthreshold value has been set to ramp GPU frequency to max freq faster (compared to panfrost) to compensate for the lower overall performance of utgard devices.
