2022-03-31drm/bridge: tc358767: Move (e)DP bridge endpoint parsing into dedicated functionMarek Vasut1-9/+21
The TC358767/TC358867/TC9595 are all capable of operating in multiple modes, DPI-to-(e)DP, DSI-to-(e)DP, DSI-to-DPI. Only the first mode is currently supported. In order to support the rest of the modes without making the tc_probe() overly long, split the bridge endpoint parsing into dedicated function, where the necessary logic to detect the bridge mode based on which endpoints are connected, can be implemented.

2022-03-31drm/edid: fix invalid EDID extension block filteringJani Nikula1-3/+3
The invalid EDID block filtering uses the number of valid EDID extensions instead of all EDID extensions for looping the extensions in the copy. This is fine, by coincidence, if all the invalid blocks are at the end of the EDID. However, it's completely broken if there are invalid extensions in the middle; the invalid blocks are included and valid blocks are excluded. Fix it by modifying the base block after, not before, the copy.

2022-03-31drm/atomic: Print the state every non-blocking commitMaxime Ripard2-4/+4
The DRM_UT_STATE controls whether we're calling drm_atomic_print_new_state() whenever a new state is committed. However, that call is made in the drm_mode_atomic_ioctl(), whereas we have multiple users of the drm_atomic_commit() function in the kernel (framebuffer emulation, drm_atomic_helper_dirtyfb, etc.). This leads to multiple states being committed but never actually displayed even though we asked to have verbose atomic state debugging. Let's move the call to drm_atomic_print_new_state() to drm_atomic_commit() to make sure we don't miss any. Non-blocking commits were never logged though, and it would create too much churn in the logs to do so, so leave them out for now.

2022-03-28drm/nouveau/kms/nv50-: atom: fix an incorrect NULL check on list iteratorXiaomeng Tong2-8/+25
The bug is here: return encoder; The list iterator value 'encoder' will *always* be set and non-NULL by drm_for_each_encoder_mask(), so it is incorrect to assume that the iterator value will be NULL if the list is empty or no element found. Otherwise it will bypass some NULL checks and lead to invalid memory access passing the check. To fix this bug, just return 'encoder' when found, otherwise return NULL.

2022-03-28drm: omapdrm: Do no allocate non-scanout GEMs through DMM/TILERIvaylo Dimitrov1-4/+8
On devices with DMM, all allocations are done through either DMM or TILER. DMM/TILER being a limited resource means that such allocations will start to fail before actual free memory is exhausted. What is even worse is that with time DMM/TILER space gets fragmented to the point that even if we have enough free DMM/TILER space and free memory, allocation fails because there is no big enough free block in DMM/TILER space. Such failures can be easily observed with OMAP xorg DDX, for example - starting few GUI applications (so buffers for their windows are allocated) and then rotating landscape<->portrait while closing and opening new windows soon results in allocation failures. Fix that by mapping buffers through DMM/TILER only when really needed, like, for scanout buffers.

2022-03-28drm: omapdrm: Support exporting of non-contiguous GEM BOsIvaylo Dimitrov3-60/+73
Currently code allocates non-scanout BOs from SHMEM and those objects are accessible to userspace by mmap(). However, on devices with no DMM (like OMAP3), the same objects are not accessible by kernel drivers that want to render to them as code refuses to export them. In turn this means that on devices with no DMM, all buffers must be allocated as scanout, otherwise only CPU can access them. On those devices, scanout buffers are allocated from CMA, making those allocations highly unreliable. Fix that by implementing functionality to export SHMEM backed buffers on devices with no DMM. This makes CMA memory only being used when needed, instead for every buffer that has to be off-CPU rendered.
