Make use of GPUVM's drm_exec helper functions preventing direct access to GPUVM internal data structures, such as the external object list. This is especially important to ensure following the locking rules around the GPUVM external object list. Fixes: ff5f643d ("drm/imagination: Add GEM and VM related code") Reviewed-by:

Fall back to drm_exec_lock_obj() if num_fences is zero for the drm_gpuvm_prepare_* function family. Otherwise dma_resv_reserve_fences() would actually allocate slots even though num_fences is zero. Cc: Christian König <christian.koenig@amd.com> Acked-by:

Instead of having a single file with all bridge chains, list bridges under a corresponding per-encoder debugfs directory. While we are at it, also slightly improve the formatting of the bridge data: split a single line entry into multiple lines, include the symbol name of the bridge funcs and add the textual representation of the bridge ops. Example of the listing: $ cat /sys/kernel/debug/dri/0/encoder-0/bridges bridge[0]: dsi_mgr_bridge_funcs type: [0] Unknown ops: [0] bridge[1]: lt9611uxc_bridge_funcs type: [11] HDMI-A OF: /soc@0/geniqup@9c0000/i2c@994000/hdmi-bridge@2b:lontium,lt9611uxc ops: [7] detect edid hpd Reviewed-by:

Define a helper for creating simple transparent bridges which serve the only purpose of linking devices into the bridge chain up to the last bridge representing the connector. This is especially useful for DP/USB-C bridge chains, which can span across several devices, but do not require any additional functionality from the intermediate bridges. Reviewed-by:

The i2c_master_send/recv() functions return negative error codes or the number of bytes that were able to be sent/received. This code has two problems. 1) Instead of checking if all the bytes were sent or received, it checks that at least one byte was sent or received. 2) If there was a partial send/receive then we should return a negative error code but this code returns success.
