This fix the deadlock with the BO reservations during SVM_BO evictions while allocations in VRAM are concurrently performed. More specific, while the ttm waits for the fence to be signaled (ttm_bo_wait), it already has the BO reserved. In parallel, the restore worker might be running, prefetching memory to VRAM. This also requires to reserve the BO, but blocks the mmap semaphore first. The deadlock happens when the SVM_BO eviction worker kicks in and waits for the mmap semaphore held in restore worker. Preventing signal the fence back, causing the deadlock until the ttm times out. We don't need to hold the BO reservation anymore during validation and mapping. Now the physical addresses are taken from hmm_range_fault. We also take migrate_mutex to prevent range migration while validate_and_map update GPU page table. Signed-off-by:

strncpy() is widely regarded as unsafe due to the fact that it may leave the destination string without a nul-termination when the source string size is too large. When compiling the kernel with W=1, the gcc warns about this: drivers/gpu/drm/drm_property.c: In function ‘drm_property_create’: drivers/gpu/drm/drm_property.c:130:2: warning: ‘strncpy’ specified bound 32 equals destination size [-Wstringop-truncation] 130 | strncpy(property->name, name, DRM_PROP_NAME_LEN); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ There are three occurrences of strncpy() in drm_property.c. None of them are actually unsafe, as the very next line forces nul-termination of the destination buffer. The warning is thus a false positive, but adds noise to the kernel log. It can easily be silenced by using strscpy_pad() instead. Do so. One of the three occurrences, in drm_property_add_enum(), fills a char array that is later copied to userspace with copy_to_user() in drm_mode_getproperty_ioctl(). To avoid leaking kernel data, strscpy_pad() is required. Similarly, a second occurrence, in drm_mode_getproperty_ioctl(), copies the string to an ioctl data buffer that isn't previously zero'ed, to strscpy_pad() is also required. The last occurrence, in drm_property_create(), would be safe to replace with strscpy(), as the destination buffer is copied to userspace with strscpy_pad(). However, given that this isn't in a hot path, let's avoid future data leaks in case someone copies the whole char array blindly. Signed-off-by: -

On R-Car Gen3, the DU uses a separate IP core named VSP to perform DMA from memory and composition of planes. The DU hardware then only handles the video timings and the interface with the encoders. This differs from Gen2, where the DU included a composer with DMA engines. When sourcing from the VSP, the DU hardware performs no memory access, and thus has no requirements on imported dma-buf memory types. The GEM CMA helpers however still create a DMA mapping to the DU device, which isn't used. The mapping to the VSP is done when processing the atomic commits, in the plane .prepare_fb() handler. When the system uses an IOMMU, the VSP device is attached to it, which enables the VSP to use non physically contiguous memory. The DU, as it performs no memory access, isn't connected to the IOMMU. The GEM CMA drm_gem_cma_prime_import_sg_table() helper will in that case fail to map non-contiguous imported dma-bufs, as the DMA mapping to the DU device will have multiple entries in its sgtable. The prevents using non physically contiguous memory for display. The DRM PRIME and GEM CMA helpers are designed to create the sgtable when the dma-buf is imported. By default, the device referenced by the drm_device is used to create the dma-buf attachment. Drivers can use a different device by using the drm_gem_prime_import_dev() function. While the DU has access to the VSP device, this won't help here, as different CRTCs use different VSP instances, connected to different IOMMU channels. The driver doesn't know at import time which CRTC a GEM object will be used, and thus can't select the right VSP device to pass to drm_gem_prime_import_dev(). To support non-contiguous memory, implement a custom .gem_prime_import_sg_table() operation that accepts all imported dma-buf regardless of the number of scatterlist entries. The sgtable will be mapped to the VSP at .prepare_fb() time, which will reject the framebuffer if the VSP isn't connected to an IOMMU. Signed-off-by:

The DU DMA address space is limited to 32 bits, so the DMA coherent mask should be set accordingly. The DMA mapping implementation will transparently map high memory buffers to 32-bit addresses through an IOMMU when present (or through bounce buffers otherwise, which isn't a supported use case as performances would be terrible). However, when sourcing frames from a VSP, the situation is more complicated. The DU delegates all memory accesses to the VSP and doesn't perform any DMA access by itself. Due to how the GEM CMA helpers are structured buffers are still mapped to the DU device. They are later mapped to the VSP as well to perform DMA access, through the IOMMU connected to the VSP. Setting the DMA coherent mask to 32 bits for the DU when using a VSP can cause issues when importing a dma_buf. If the buffer is located above the 32-bit address space, the DMA mapping implementation will try to map it to the DU's DMA address space. As the DU has no IOMMU a bounce buffer will be allocated, which in the best case will waste memory and in the worst case will just fail. To work around this issue, set the DMA coherent mask to the full 40-bit address space for the DU. All dma-buf instances will be imported without any restriction, and will be mapped to the VSP when preparing the associated framebuffer. Signed-off-by:

On R-Car D3 and E3, the LVDS encoders provide the pixel clock to the DU, even when LVDS outputs are not used. For this reason, the rcar-lvds driver probes successfully on those platforms even if no further bridge or panel is connected to the LVDS output, in order to provide the rcar_lvds_clk_enable() and rcar_lvds_clk_disable() functions to the DU driver. If an LVDS output isn't connected, trying to create a DRM connector for the output will fail. Fix this by skipping connector creation in that case, and also skip creation of the DRM encoder as there's no point in an encoder without a connector.
