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.

This introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, we try to preserve it. Apart from old versions of the vmwgfx xorg driver, there is nothing depending on rmfb disabling a crtc. Vmwgfx' and simple kms helper atomic implementation rejects CRTC enabled without plane, so we can do this safely. If the atomic commit is rejected by the driver then we will still fall back to the old behavior and turn off the crtc. Changes since v1: - Restart completely when rmfb with crtc on fails (Sean Paul).

drm_add_edid_modes() now fills in the ELD automatically, so the calls to drm_edid_to_eld() are redundant. Remove them.

Jani Nikula authored
Since drm_edid_to_eld() knows the connector type, we can set the type in ELD while at it. Most connectors this gets called on are not DP encoders, and with the HDMI type being 0, this does not change behaviour for non-DP. For i915 having this in place earlier would have saved a considerable amount of debugging that lead to the fix 2d8f6329 ("drm/i915: always update ELD connector type after get modes"). I don't see other drivers, even the ones calling drm_edid_to_eld() on DP connectors, setting the connector type in ELD.

We want to remove uses of do_gettimeofday() from the kernel since the resulting timeval structure overflows in 2038. This is not a problem for this particular use, but do_gettimeofday() is also not an appropriate method for measuring time intervals, since it requires a conversion into microseconds and is complicated to work with. ktime_get() is a better replacement, as it works with the monontonic kernel timebase and requires a minimum of computation. I'm slightly changing the output from microseconds to nanoseconds here, to avoid introducing a new division operation. This should be fine since the value is only used for debugging. Signed-off-by:
