2024-12-05drm/display: hdmi: add generic mode_valid helperDmitry Baryshkov2-5/+277
Add drm_hdmi_connector_mode_valid(), generic helper for HDMI connectors. It can be either used directly or as a part of the .mode_valid callback.

The set_connector_edid() function returns a bogus 0, performing the check on the connector->funcs->fill_modes() result internally. Make the function pass the fill_modes()'s return value to the caller and move corresponding checks to the caller site.

The new mock struct allows to share variables and even further mocks over the tests in a cleaner way than using dev_private void pointer.

2024-05-28drm/connector: hdmi: Add Infoframes generationMaxime Ripard2-0/+13
Infoframes in KMS is usually handled by a bunch of low-level helpers that require quite some boilerplate for drivers. This leads to discrepancies with how drivers generate them, and which are actually sent. Now that we have everything needed to generate them in the HDMI connector state, we can generate them in our common logic so that drivers can simply reuse what we precomputed.

This had a bunch of kunit tests to make sure our code to handle the Broadcast RGB property behaves properly.

2024-05-28drm/connector: hdmi: Add custom hook to filter TMDS character rateMaxime Ripard2-0/+18
Most of the HDMI controllers have an upper TMDS character rate limit they can't exceed. On "embedded"-grade display controllers, it will typically be lower than what high-grade monitors can provide these days, so drivers will filter the TMDS character rate based on the controller capabilities. To make that easier to handle for drivers, let's provide an optional hook to be implemented by drivers so they can tell the HDMI controller helpers if a given TMDS character rate is reachable for them or not. This will then be useful to figure out the best format and bpc count for a given mode.

2024-05-28drm/connector: hdmi: Calculate TMDS character rateMaxime Ripard1-0/+3
Most HDMI drivers have some code to calculate the TMDS character rate, usually to adjust an internal clock to match what the mode requires. Since the TMDS character rates mostly depends on the resolution, whether we need to repeat pixels or not, the bpc count and the format, we can now derive it from the HDMI connector state that stores all those infos and remove the duplication from drivers.

- Add tracking clear page feature. - Driver should enable the DRM_BUDDY_CLEARED flag if it successfully clears the blocks in the free path. On the otherhand, DRM buddy marks each block as cleared. - Track the available cleared pages size - If driver requests cleared memory we prefer cleared memory but fallback to uncleared if we can't find the cleared blocks. when driver requests uncleared memory we try to use uncleared but fallback to cleared memory if necessary. - When a block gets freed we clear it and mark the freed block as cleared, when there are buddies which are cleared as well we can merge them. Otherwise, we prefer to keep the blocks as separated. - Add a function to support defragmentation. v1: - Depends on the flag check DRM_BUDDY_CLEARED, enable the block as cleared. Else, reset the clear flag for each block in the list(Christian) - For merging the 2 cleared blocks compare as below, drm_buddy_is_clear(block) != drm_buddy_is_clear(buddy)(Christian) - Defragment the memory beginning from min_order till the required memory space is available. v2: (Matthew) - Add a wrapper drm_buddy_free_list_internal for the freeing of blocks operation within drm buddy. - Write a macro block_incompatible() to allocate the required blocks. - Update the xe driver for the drm_buddy_free_list change in arguments. - add a warning if the two blocks are incompatible on defragmentation - call full defragmentation in the fini() function - place a condition to test if min_order is equal to 0 - replace the list with safe_reverse() variant as we might remove the block from the list. v3: - fix Gitlab user reported lockup issue. - Keep DRM_BUDDY_HEADER_CLEAR define sorted(Matthew) - modify to pass the root order instead max_order in fini() function(Matthew) - change bool 1 to true(Matthew) - add check if min_block_size is power of 2(Matthew) - modify the min_block_size datatype to u64(Matthew) v4: - rename the function drm_buddy_defrag with __force_merge. - Include __force_merge directly in drm buddy file and remove the defrag use in amdgpu driver. - Remove list_empty() check(Matthew) - Remove unnecessary space, headers and placement of new variables(Matthew) - Add a unit test case(Matthew) v5: - remove force merge support to actual range allocation and not to bail out when contains && split(Matthew) - add range support to force merge function. v6: - modify the alloc_range() function clear page non merged blocks allocation(Matthew) - correct the list_insert function name(Matthew).
