Pin and vmap are distinct operations. Do not perform a pin as part of the vmap call. This used to be necessary to keep the fbdev buffer in place while it is being updated. Fbdev emulation has meanwhile been fixed to lock the buffer correctly. Same for vunmap. For refactoring the code, remove the pin calls from the helper's vmap implementation in drm_gem_vram_vmap() and inline the call to drm_gem_vram_kmap_locked(). This gives a vmap helper that only maps the buffer object's memory pages without pinning or locking. Do a similar refactoring for vunmap.

2024-03-11drm/client: Pin vmap'ed GEM buffersThomas Zimmermann
The function drm_client_buffer_vmap() establishes a long-term mapping of the client's buffer object into the kernel address space. Make sure that buffer does not move by pinning it to its current location. Same for vunmap with unpin. The only caller of drm_client_buffer_vmap() is fbdev-dma, which uses gem-dma. As DMA-backed GEM buffers do not move, this change is for correctness with little impact in practice.

2024-03-11drm/fbdev-generic: Fix locking with drm_client_buffer_vmap_local()Thomas Zimmermann
Temporarily lock the fbdev buffer object during updates to prevent memory managers from evicting/moving the buffer. Moving a buffer object while update its content results in undefined behaviour. Fbdev-generic updates its buffer object from a shadow buffer. Gem-shmem and gem-dma helpers do not move buffer objects, so they are safe to be used with fbdev-generic. Gem-vram and qxl are based on TTM, but pin buffer objects are part of the vmap operation. So both are also safe to be used with fbdev-generic. Amdgpu and nouveau do not pin or lock the buffer object during an update. Their TTM-based memory management could move the buffer object while the update is ongoing. The new vmap_local and vunmap_local helpers hold the buffer object's reservation lock during the buffer update. This prevents moving the buffer object on all memory managers.

2024-03-11drm/gem: Acquire reservation lock in drm_gem_{pin/unpin}()Thomas Zimmermann
Acquire the buffer object's reservation lock in drm_gem_pin() and remove locking the drivers' GEM callbacks where necessary. Same for unpin(). DRM drivers and memory managers modified by this patch will now have correct dma-buf locking semantics: the caller is responsible for holding the reservation lock when calling the pin or unpin callback. DRM drivers and memory managers that are not modified will now be protected against concurent invocation of their pin and unpin callbacks. PRIME does not implement struct dma_buf_ops.pin, which requires the caller to hold the reservation lock. It does implement struct dma_buf_ops.attach, which requires to callee to acquire the reservation lock. The PRIME code uses drm_gem_pin(), so locks are now taken as specified. Same for unpin and detach. The patch harmonizes GEM pin and unpin to have non-interruptible reservation locking across all drivers, as is already the case for vmap and vunmap. This affects gem-shmem, gem-vram, loongson, qxl and radeon.

2024-03-11drm/panthor: Fix undefined panthor_device_suspend/resume symbol issueBoris Brezillon
panthor_device_resume/suspend() are only compiled when CONFIG_PM is enabled but panthro_drv.c doesn't use the pm_ptr() macro to conditionally discard resume/suspend assignments, which causes undefined symbol errors at link time when !PM. We could fix that by using pm_ptr(), but supporting the !PM case makes little sense (the whole point of these embedded GPUs is to be low power, so proper PM is a basic requirement in that case). So let's just enforce the presence of CONFIG_PM with a Kconfig dependency instead. If someone needs to relax this dependency, it can be done in a follow-up.
