This reverts commit 3510e7a7. During the 4.19 merge window for drm-misc, two patches critical to supporting the display pipeline on the Allwinner R40 SoC were missed. They were applied later but missed the merge window deadline. As a result 4.19-rc1 kernel would crash on the R40 when it couldn't parse the new device tree structure. We ended up removing support for the R40 display pipeline for 4.19. Since the missing patches are already merged for 4.20, we can now revert the commit that removed support. Signed-off-by:

The lcdif block is only powered on when display is active so plane updates when not enabled are not valid. Writing to an unpowered IP block is mostly ignored but can trigger bus errors on some chips. Prevent this situation by switching to drm_atomic_helper_commit_tail_rpm and having the drm core ensure atomic_plane_update is only called while the crtc is active. This avoids having to keep track of "enabled" bits inside the mxsfb driver. This also requires handling the vblank event for disable from mxsfb_pipe_disable. Signed-off-by:

LCDIF will repeatedly display data from CUR_BUF and set CUR_BUF to NEXT_BUF when done. Since we are only ever writing to NEXT_BUF the display will show an initial corrupt frame. Fix by writing the FB paddr to both CUR_BUF and NEXT_BUF when activating the CRTC. Signed-off-by:

The main axi clk is disabled at the end of mxsfb_crtc_mode_set_nofb and immediately reenabled in mxsfb_enable_controller. Avoid this by moving the handling of axi clk one level up to mxsfb_crtc_enable. Do the same for mxsfb_crtc_disable for symmetry. This shouldn't have any functional effect. Signed-off-by:

All Tegra DRM devices are getting attached to an implicit IOMMU DMA domain if CONFIG_ARM_DMA_USE_IOMMU=y. Since Tegra DRM driver manages IOMMU by itself, the devices must be detached from the implicit domain using arch-specific IOMMU-API. Note that this works only for arm32 and not for arm64, which will remain broken if CONFIG_IOMMU_DMA is enabled. Signed-off-by:

The display hub integrated into Tegra194 is almost identical to the one found on Tegra186. However, it doesn't support DSC (display stream compression) so it isn't fully compatible. Signed-off-by: -
Thierry Reding authored
Tegra194 contains a fourth display controller that does not own any windows. Therefore, we cannot currently assign a primary plane to it which causes KMS to eventually crash. Do not register the display controller if it owns no windows to work around this. Note that we still have to enable and probe the display controller because for some reason all display controllers need to be powered (and/or clocked) before any registers can be accessed in any of the display controllers.

Implement vmap/vunmap so we can export dmabufs to other drivers, such as video4linux. Tested with a virtio-gpu / vivid (virtual capture driver) pipeline, where the vivid driver imports the dmabufs exported by virtio-gpu. Note that dma_buf_vmap() does its own vmap counting, so it's not needed to take care of it in the driver. Signed-off-by:

Currently, virtio_gpu_object_kmap() is only called by virtio_gpufb_create(), when a DRM framebuffer is created. Thus, instead of returning the vmap'ed address, emit a warning if virtio_gpu_object_kmap is called on an already mapped object. With this change, kmap/kunmap calls are now balanced. Signed-off-by:

The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch. Signed-off-by:

Currently the driver overwrites the surface depth provided by the fb helper to give an invalid bpp/surface depth combination. This has been exposed by commit 70109354 ("drm: Reject unknown legacy bpp and depth for drm_mode_addfb ioctl"), which now causes the driver to fail to probe. Fix by not overwriting the surface depth.

In hibmc_drm_fb_create(), when the call to hibmc_framebuffer_init() fails with error, do not store the error code in the HiBMC device frame-buffer pointer, as this will be later checked for non-zero value in hibmc_fbdev_destroy() when our intention is to check for a valid function pointer.

Use DRM_FORMAT_HOST_XRGB8888, so we are using the correct format code on bigendian machines. Also set the quirk_addfb_prefer_host_byte_order mode_config bit so drm_mode_addfb() asks for the correct format code. Both DRM_FORMAT_* and VIRTIO_GPU_FORMAT_* are defined to be little endian, so using a different mapping on bigendian machines is wrong. It's there because of broken drm_mode_addfb() behavior. So with drm_mode_addfb() being fixed we can fix this too. While wading through the code I've noticed we have a little issue in virtio: We attach a format to the bo when it is created (DRM_IOCTL_MODE_CREATE_DUMB), not when we map it as framebuffer (DRM_IOCTL_MODE_ADDFB). Easy way out: Support a single format only. Pick DRM_FORMAT_HOST_XRGB8888, it is the only one actually used in practice. Drop unused mappings in virtio_gpu_translate_format(). With this patch applied both ADDFB and ADDFB2 ioctls work correctly in the virtio-gpu.ko driver on big endian machines. Without the patch only ADDFB (which still seems to be used by the majority of userspace) works correctly. Signed-off-by:
