2019-07-15T16:11:31+00:00

Drop use of the deprecated drmP.h header file. Fix fallout by adding missing include files.

drm: Split out drm_probe_helper.h

2019-01-24T12:20:42+00:00

Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

drm/virtio: Remove incorrect kfree()

2019-01-08T10:45:19+00:00

The virtio_gpu_output is a member of struct virtio_gpu_device and is not a dynamically-allocated chunk, so it's wrong to kfree() it. Removing it fixes a memory corruption BUG() that can be triggered when the virtio-gpu driver is removed.

drm/virtio: fix DRM_FORMAT_* handling

2018-09-25T12:49:49+00:00

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.
