The implementation of vmap and vunmap for GEM VRAM helpers is already in PRIME helpers. The patch moves the operations to separate functions and exports them for general use. v3: * remove v2's obsolete note on ref-counting v2: * fix documentation * add cross references to function documentation * document (the lack of) ref-counting for GEM VRAM BO mappings Signed-off-by:

Adds to print the event message when error happens and the same event will not be printed until next vsync. Changes since v2: 1. Refine komeda_sprintf(); 2. Not using STR_SZ macro for the string size in komeda_print_events(). Changes since v1: 1. Handling the event print by CONFIG_KOMEDA_ERROR_PRINT; 2. Changing the max string size to 256. Signed-off-by:

Currently we restrict the number of encoders that can be linked to a connector to 3, increase it to match the maximum number of encoders that can be initialized(32). To more effiently do that lets switch from an array of encoder ids to bitmask. v2: Fixing missed return on amdgpu_dm_connector_to_encoder() Suggested-by:

This 3 non-atomic drivers all have the same function getting the only encoder available in the connector, also atomic drivers have this fallback. So moving it a common place and sharing between atomic and non-atomic drivers. While at it I also removed the mention of drm_atomic_helper_best_encoder() that was renamed in commit 297e30b5 ("drm/atomic-helper: Unexport drm_atomic_helper_best_encoder"). v3: moving drm_connector_get_single_encoder to drm_kms_helper module Reviewed-by:

When transmitting IEC60985 linear PCM audio, we configure the Aduio Sample Channel Status information in the IEC60958 frame. The status bit is already available in iec.status of hdmi_codec_params. This fix the issue that audio does not come out on some monitors (e.g. LG 22CV241) Note that these registers are only for interfaces: I2S audio interface, General Purpose Audio (GPA), or AHB audio DMA (AHBAUDDMA). For S/PDIF interface this information comes from the stream. Currently this function dw_hdmi_set_channel_status is only called from dw-hdmi-i2s-audio in I2S setup. Signed-off-by:

VRAM MM and GEM VRAM buffer objects are only used with each other; connected via 3 function pointers. Simplify this code by making the memory manager call the rsp. functions of the BOs directly; and remove the functions from the BO's public interface. v2: * typos in commit message Signed-off-by:

Thomas Zimmermann authored
The separation between GEM VRAM objects and the memory manager is artificial, as they are only used with each other. Copying both implementations into the same file is a first step to simplifying the code.

Rename the embedded struct vma_offset_manager, new name is _vma_manager. ttm_bo_device.vma_manager changed to a pointer. The ttm_bo_device_init() function gets an additional vma_manager argument which allows to initialize ttm with a different vma manager. When passing NULL the embedded _vma_manager is used. All callers are updated to pass NULL, so the behavior doesn't change. Signed-off-by:
