Add helper function to mmap ttm bo's using &drm_gem_object_funcs.mmap(). Note that with this code path access verification is done by drm_gem_mmap() (which calls drm_vma_node_is_allowed(()). The &ttm_bo_driver.verify_access() callback is is not used. v3: use ttm_bo_mmap_obj instead of ttm_bo_mmap_vma_setup Signed-off-by:

Rename ttm_fbdev_mmap to ttm_bo_mmap_obj. Move the vm_pgoff sanity check to amdgpu_bo_fbdev_mmap (only ttm_fbdev_mmap user in tree). The ttm_bo_mmap_obj function can now be used to map any buffer object. This allows to implement &drm_gem_object_funcs.mmap in gem ttm helpers. v3: patch added to series Signed-off-by:

Not obvious why this is needed. According to Deniel Vetter this is most likely a historic artefact dating back to the days where drm drivers exposed hardware registers as mmap'able gem objects, to avoid dumping touching those registers. shmem gem objects surely don't need that ... Signed-off-by:

Switch gem shmem helper to the new mmap() workflow, from &gem_driver.fops.mmap to &drm_gem_object_funcs.mmap. v2: Fix vm_flags and vm_page_prot handling. Signed-off-by:
-
Gerd Hoffmann authored
drm_gem_object_funcs->vm_ops alone can't handle everything which needs to be done for mmap(), tweaking vm_flags for example. So add a new mmap() callback to drm_gem_object_funcs where this code can go to. Note that the vm_ops field is not used in case the mmap callback is present, it is expected that the callback sets vma->vm_ops instead. Also setting vm_flags and vm_page_prot is the job of the new callback. so drivers have more control over these flags. drm_gem_mmap_obj() will use the new callback for object specific mmap setup. With this in place the need for driver-speific fops->mmap callbacks goes away, drm_gem_mmap can be hooked instead. drm_gem_prime_mmap() will use the new callback too to just mmap gem objects directly instead of jumping though loops to make drm_gem_object_lookup() and fops->mmap work.

When setting a new display mode, dw_hdmi_setup() calls dw_hdmi_enable_video_path(), which disables all hdmi clocks, including the audio clock. We should only (re-)enable the audio clock if audio was already enabled when setting the new mode. Without this patch, on RK3288, there will be HDMI audio on some monitors if i2s was played to headphone when the monitor was plugged. ACER H277HU and ASUS PB278 are two of the monitors showing this issue. Signed-off-by:

On SoCs with DMM/TILER, we have two ways to allocate buffers: normal dma_alloc or via DMM (which basically functions as an IOMMU). DMM can map 128MB at a time, and we only map the DMM buffers when they are used (i.e. not at alloc time). If DMM is present, omapdrm always uses DMM. There are use cases that require lots of big buffers that are being used at the same time by different IPs. At the moment the userspace has a hard maximum of 128MB. This patch adds three new flags that can be used by the userspace to solve the situation: OMAP_BO_MEM_CONTIG: The driver will use dma_alloc to get the memory. This can be used to avoid DMM if the userspace knows it needs more than 128M of memory at the same time. OMAP_BO_MEM_DMM: The driver will use DMM to get the memory. There's not much use for this flag at the moment, as on platforms with DMM it is used by default, but it's here for completeness. OMAP_BO_MEM_PIN: The driver will pin the memory at alloc time, and keep it pinned. This can be used to 1) get an error at alloc time if DMM space is full, and 2) get rid of the constant pin/unpin operations which may have some effect on performance. If none of the flags are given, the behavior is the same as currently. Signed-off-by:

omap_gem_new() has a comment about OMAP_BO_SCANOUT which does not make sense. Also, for the TILER case, we drop OMAP_BO_SCANOUT flag for some reason. It's not clear what the original purpose of OMAP_BO_SCANOUT is, but presuming it means "scanout buffer, something that can be consumed by DSS", this patch cleans up the above issues. Signed-off-by:

OMAP_BO_TILED does not make sense, as OMAP_BO_TILED_* values are not bitmasks but normal values. As we already have OMAP_BO_TILED_MASK for the mask, we can remove OMAP_BO_TILED and use OMAP_BO_TILED_MASK instead. Signed-off-by:

Add an optional CRTC gamma LUT support, and enable it on RK3288. This is currently enabled via a separate address resource, which needs to be specified in the devicetree. The address resource is required because on some SoCs, such as RK3288, the LUT address is after the MMU address, and the latter is supported by a different driver. This prevents the DRM driver from requesting an entire register space. The current implementation works for RGB 10-bit tables, as that is what seems to work on RK3288. Tested-by:
