drm_plane_helper_check_update() isn't a transitional helper, so let's rename it to drm_atomic_helper_check_plane_state() and move it into drm_atomic_helper.c. v2: Fix the WARNs about plane_state->crtc matching crtc_state->crtc Cc: Daniel Vetter <daniel@ffwll.ch> Suggested-by:

drm_plane_helper_check_state() is supposed to do things the atomic way, so it should not be inspecting crtc->enabled. Rather we should be looking at crtc_state->enable. We have a slight complication due to drm_plane_helper_check_update() reusing drm_plane_helper_check_state() for non-atomic drivers. Thus we'll have to pass the crtc_state in manally and construct a fake crtc_state in drm_plane_helper_check_update(). v2: Fix the WARNs about plane_state->crtc matching crtc_state->crtc Signed-off-by:

Try to fix the code to actually clip the plane to the crtc bounds instead of the user provided crtc coordinates (which would be a no-op since those are exactly the coordinates before clipping).

There is no need to #define the license of the driver, just put it in the MODULE_LICENSE() line directly as a text string. This allows tools that check that the module license matches the source code license to work properly, as there is no need to unwind the unneeded dereference, especially when the string is defined in a .h file far away from the .c file it is used in.

The i2c adapter on DP AUX is purely a software construct. Linking it to the device node of the parent device is wrong, as it leads to 2 devices sharing the same device node, which is bad practice, as well as the i2c trying to populate children of the i2c adapter by looking at the child device nodes of the parent device.

If the sink device is in HDMI mode, enable infoframe interrupt in scdt irq handle function else call start_video function immediately, because in DVI mode, there is no infoframe interrupt provided. Rename start_hdmi function to start_video and get rid of the old start_video function. In start_video, if the sink is DVI and mode is MHL1 or MHl2, write appropriate values to registers else the path should remain the same as in HDMI mode. Signed-off-by:

drm_gem_cma_prime_import_sg_table() will fail if the number of entries in the sg_table > 1. However, you can have a device that uses an IOMMU engine and can map a discontiguous buffer with multiple entries that have consecutive sg_dma_addresses, effectively making it contiguous. Allow for that scenario by testing the entries in the sg_table for contiguous coverage. Reviewed-by:

The introduction of: drm/framebuffer: Add framebuffer debugfs file broke vgem. That patch assumed that all drivers had initialized the dev->mode_config.fb_lock mutex which happens in drm_mode_config_init(). vgem doesn't need to call drm_mode_config_init(). Fix this by only creating the framebuffer debugfs file for modesetting drivers. Fixes: 45d58b40 ("drm/framebuffer: Add framebuffer debugfs file") Suggested-by:

Add drm_gem_cma_print_info() for debugfs printing struct drm_gem_cma_object specific info. Reviewed-by:

This allows the argument to be a const. The other option was to keep it an inline function and make the argument a const: static inline struct drm_gem_cma_object * to_drm_gem_cma_obj(const struct drm_gem_object *gem_obj) { return container_of(gem_obj, struct drm_gem_cma_object, base); } This will happily return a non-const pointer to the drm_gem_cma_object based on a const pointer to the contained drm_gem_object, thus creating const-safety problems. There was an attempt to fix the problem in the container_of() macro itself (see https://lkml.org/lkml/2017/5/19/381) but the patch seems to have fallen through the cracks. It would require turning this inline function into a macro. By making this a macro now, we will benefit from a possible future enhancement of container_of(). We don't loose type checking by doing this, container_of() takes care of that. Suggested-by: -

Simply mmap'ing /dev/dri/card0 repeatedly will spam the kernel log with qxl_mmap information messages. The following example code illustrates this: int main(void) { int fd = open("/dev/dri/card0", O_RDONLY); if (fd == -1) err(1, "open failed"); for (;;) { void *m = mmap(NULL, 4096, PROT_READ, MAP_SHARED, fd, 0); if (m != MAP_FAILED) munmap(m, 4096); } } Stop the spamming by removing the pr_info message. Since the mmap'ing returns -EINVAL there is no need for the pr_info message.
