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:

Thomas Zimmermann authored
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:

Now with ttm_buffer_object being a subclass of drm_gem_object we can easily lookup ttm_buffer_object for a given drm_gem_object, which in turn allows to create common helper functions.

Frequent mapping and unmapping a buffer object adds overhead for modifying the page table and creates debug output. Unmapping a buffer is only required when the memory manager evicts the buffer from its current location. v4: * WARN_ON if buffer is still mapped during BO cleanup Signed-off-by:

The implementation of vmap() is a combined pin() and kmap(). As both functions share the same lock, we can make vmap() slightly faster by acquiring the lock only once for both operations. Same for the inverse, vunmap(). Signed-off-by:

Thomas Zimmermann authored
The kmap and kunmap operations of GEM VRAM buffers can now be called in interleaving pairs. The first call to drm_gem_vram_kmap() maps the buffer's memory to kernel address space and the final call to drm_gem_vram_kunmap() unmaps the memory. Intermediate calls to these functions increment or decrement a reference counter. This change allows for keeping buffer memory mapped for longer and minimizes the amount of changes to TLB, page tables, etc. v4: * lock in kmap()/kunmap() with ttm_bo_reserve() Signed-off-by:

The implementation of functions encoder_enable and encoder_disable make possible to control the pinctrl according to the encoder type. The pinctrl must be activated only if the encoder type is DPI. This helps to move the DPI-related pinctrl configuration from all the panel or bridge to the LTDC dt node. Reviewed-by:
