2022-02-22drm: implement top-down allocation methodArunpravin1-0/+1
Implemented a function which walk through the order list, compares the offset and returns the maximum offset block, this method is unpredictable in obtaining the high range address blocks which depends on allocation and deallocation. for instance, if driver requests address at a low specific range, allocator traverses from the root block and splits the larger blocks until it reaches the specific block and in the process of splitting, lower orders in the freelist are occupied with low range address blocks and for the subsequent TOPDOWN memory request we may return the low range blocks.To overcome this issue, we may go with the below approach. The other approach, sorting each order list entries in ascending order and compares the last entry of each order list in the freelist and return the max block. This creates sorting overhead on every drm_buddy_free() request and split up of larger blocks for a single page request. v2: - Fix alignment issues(Matthew Auld) - Remove unnecessary list_empty check(Matthew Auld) - merged the below patch to see the feature in action - add top-down alloc support to i915 driver Signed-off-by: Arunpravin <[email protected]> Reviewed-by: Matthew Auld <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Christian König <[email protected]>

2022-02-15drm: Plumb debugfs_init through to panelsDouglas Anderson3-0/+22
We'd like panels to be able to add things to debugfs underneath the connector's directory. Let's plumb it through. A panel will be able to put things in a "panel" directory under the connector's directory. Note that debugfs is not ABI and so it's always possible that the location that the panel gets for its debugfs could change in the future. NOTE: this currently only works if you're using a modern architecture. Specifically the plumbing relies on _both_ drm_bridge_connector and drm_panel_bridge. If you're not using one or both of these things then things won't be plumbed through. As a side effect of this change, drm_bridges can also get callbacks to put stuff underneath the connector's debugfs directory. At the moment all bridges in the chain have their debugfs_init() called with the connector's root directory.

2022-02-07dma-buf-map: Rename to iosys-mapLucas De Marchi13-45/+53
Rename struct dma_buf_map to struct iosys_map and corresponding APIs. Over time dma-buf-map grew up to more functionality than the one used by dma-buf: in fact it's just a shim layer to abstract system memory, that can be accessed via regular load and store, from IO memory that needs to be acessed via arch helpers. The idea is to extend this API so it can fulfill other needs, internal to a single driver. Example: in the i915 driver it's desired to share the implementation for integrated graphics, which uses mostly system memory, with discrete graphics, which may need to access IO memory. The conversion was mostly done with the following semantic patch: @r1@ @@ - struct dma_buf_map + struct iosys_map @r2@ @@ ( - DMA_BUF_MAP_INIT_VADDR + IOSYS_MAP_INIT_VADDR | - dma_buf_map_set_vaddr + iosys_map_set_vaddr | - dma_buf_map_set_vaddr_iomem + iosys_map_set_vaddr_iomem | - dma_buf_map_is_equal + iosys_map_is_equal | - dma_buf_map_is_null + iosys_map_is_null | - dma_buf_map_is_set + iosys_map_is_set | - dma_buf_map_clear + iosys_map_clear | - dma_buf_map_memcpy_to + iosys_map_memcpy_to | - dma_buf_map_incr + iosys_map_incr ) @@ @@ - #include <linux/dma-buf-map.h> + #include <linux/iosys-map.h> Then some files had their includes adjusted and some comments were update to remove mentions to dma-buf-map.

2022-01-25drm/edid: Split deep color modes between RGB and YUV444Maxime Ripard1-3/+9
The current code assumes that the RGB444 and YUV444 formats are the same, but the HDMI 2.0 specification states that: The three DC_XXbit bits above only indicate support for RGB 4:4:4 at that pixel size. Support for YCBCR 4:4:4 in Deep Color modes is indicated with the DC_Y444 bit. If DC_Y444 is set, then YCBCR 4:4:4 is supported for all modes indicated by the DC_XXbit flags. So if we have YUV444 support and any DC_XXbit flag set but the DC_Y444 flag isn't, we'll assume that we support that deep colour mode for YUV444 which breaks the specification. In order to fix this, let's split the edid_hdmi_dc_modes field in struct drm_display_info into two fields, one for RGB444 and one for YUV444.

2022-01-25drm/docs: Document where the C8 color lut is storedDaniel Vetter1-0/+10
Also add notes that for atomic drivers it's really somewhere else and no longer in struct drm_crtc. Maybe we should put a bigger warning here that this is confusing, since the pixel format is a plane property, but the GAMMA_LUT property is on the crtc. But I think we can fix this if/when someone finds a need for a per-plane CLUT, since I'm not sure such hw even exists. I'm also not sure whether even hardware with a CLUT and a full color correction pipeline with degamm/cgm/gamma exists. Motivated by comments from Geert that we have a gap here. v2: More names for color luts (Laurent).

2021-12-22drm: Always include the debugfs dentry in drm_crtcVille Syrjälä1-2/+0
Remove the counterproductive CONFIG_DEBUG_FS ifdef and just include the debugfs dentry in drm_crtc always. This way we don't need annoying ifdefs in the actual code with DEBUGFS=n. Also we don't have these ifdefs around any of the other debugfs dentries either so can't see why drm_crtc should be special. This fixes the i915 DEBUGFS=n build because I assumed the dentry would always be there.
