DCSS supports 90/180/270 degree rotations for Vivante tiled and super-tiled formats. Unfortunately, with the current code, they didn't work properly. This simple patch makes the rotations work by fixing the way the scaler is set up for 90/270 degree rotations. In this particular case, the source width and height need to be swapped since DPR is sending the buffer to scaler already rotated. Also, make sure to allow full rotations for DRM_FORMAT_MOD_VIVANTE_SUPER_TILED. Fixes: 9021c317 ("drm/imx: Add initial support for DCSS on iMX8MQ") Signed-off-by:

Flushing the fbdev's shadow buffer requires vmap'ing the BO memory, which in turn requires pinning the BO. While being pinned, the BO cannot be moved into VRAM for scanout. Consequently, a concurrent modeset operation that involves the fbdev framebuffer would likely fail. Resolve this problem be acquiring the modeset lock of the planes that use the fbdev framebuffer. On non-atomic drivers, also acquire the mode-config lock. This serializes the flushing of the framebuffer with concurrent modeset operations. v2: * only acquire struct drm_fb_helper.lock in damage blitter (Daniel, Christian) Signed-off-by:

DRM client's vmap/vunmap functions don't allow for multiple vmap operations. Calling drm_client_buffer_vmap() twice returns the same mapping, then calling drm_client_buffer_vunmap() twice already unmaps on the first call. This leads to unbalanced vmap refcounts. Fix this by calling drm_gem_vmap() unconditionally in drm_client_buffer_vmap(). All drivers that support DRM clients have to implement correct ref- counting for their vmap operations, or not vunmap at all. This is the case for drivers that use CMA, SHMEM and VRAM helpers, and QXL. Other drivers are not affected. Signed-off-by:

Thomas Zimmermann authored
SHMEM-buffer backing storage is allocated from system memory; which is typically cachable. The default mode for SHMEM objects is writecombine though. Unify SHMEM semantics by defaulting to cached mappings. The exception is pages imported via dma-buf. DMA memory is usually not cached. DRM drivers that require write-combined mappings set the map_wc flag in struct drm_gem_shmem_object to true. This currently affects lima, panfrost and v3d. The drivers mgag200, udl, virtio and vkms continue to use default shmem mappings. The drivers cirrus and gm12u320 change caching flags. Both used writecombine and now switch over to shmem defaults. Both drivers use SHMEM objects as shadow buffers for internal video memory, so cached mappings will not affect them negatively. v3: * set value of shmem pointer before dereferencing it in __drm_gem_shmem_create() (Dan, kernel test robot) v2: * recreate patch on top of latest SHMEM helpers * update lima, panfrost, v3d to select writecombine (Daniel, Rob) Signed-off-by:

This implements support for DPI output using the port node in the device tree to connect a DPI LCD display to the MCDE. The block also supports TV-out but we leave that for another day when we have a hardware using it. We implement parsing and handling of the "port" node, and follow that to the DPI endpoint. The clock divider used by the MCDE to divide down the "lcdclk" (this has been designed for TV-like frequencies) is represented by an ordinary clock provider internally in the MCDE. This idea was inspired by the PL111 solution by Eric Anholt: the divider also works very similar to the Pl111 clock divider. We take care to clear up some errors regarding the number of available formatters and their type. We have 6 DSI formatters and 2 DPI formatters. Tested on the Samsung GT-I9070 Janice mobile phone.

I was confused when the graphics came out with blue penguins on the DPI panel. It turns out that the so-called "packed RGB666" mode on the DSI formatter is incorrect: this mode is the actual RGB888 mode, and the mode called RGB888 is BGR888. The claims that the MCDE had inverse RGB/BGR buffer formats was wrong, so correct this and the buggy register and everything is much more consistent, and graphics look good on all targets, both DPI and DSI.

This patch is basically a port of Ørjan Eide's similar patch for ION https://lore.kernel.org/lkml/20200414134629.54567-1-orjan.eide@arm.com/ Only sync the sg-list of dma-buf heap attachment when the attachment is actually mapped on the device. dma-bufs may be synced at any time. It can be reached from user space via DMA_BUF_IOCTL_SYNC, so there are no guarantees from callers on when syncs may be attempted, and dma_buf_end_cpu_access() and dma_buf_begin_cpu_access() may not be paired. Since the sg_list's dma_address isn't set up until the buffer is used on the device, and dma_map_sg() is called on it, the dma_address will be NULL if sync is attempted on the dma-buf before it's mapped on a device. Before v5.0 (commit 55897af6 ("dma-direct: merge swiotlb_dma_ops into the dma_direct code")) this was a problem as the dma-api (at least the swiotlb_dma_ops on arm64) would use the potentially invalid dma_address. How that failed depended on how the device handled physical address 0. If 0 was a valid address to physical ram, that page would get flushed a lot, while the actual pages in the buffer would not get synced correctly. While if 0 is an invalid physical address it may cause a fault and trigger a crash. In v5.0 this was incidentally fixed by commit 55897af6 ("dma-direct: merge swiotlb_dma_ops into the dma_direct code"), as this moved the dma-api to use the page pointer in the sg_list, and (for Ion buffers at least) this will always be valid if the sg_list exists at all. But, this issue is re-introduced in v5.3 with commit 449fa54d ("dma-direct: correct the physical addr in dma_direct_sync_sg_for_cpu/device") moves the dma-api back to the old behaviour and picks the dma_address that may be invalid. dma-buf core doesn't ensure that the buffer is mapped on the device, and thus have a valid sg_list, before calling the exporter's begin_cpu_access.

In preparation for some patches to optmize the system heap code, rework the dmabuf exporter to utilize sgtables rather then pageslists for tracking the associated pages. This will allow for large order page allocations, as well as more efficient page pooling. In doing so, the system heap stops using the heap-helpers logic which sadly is not quite as generic as I was hoping it to be, so this patch adds heap specific implementations of the dma_buf_ops function handlers.
