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. All the other places are obvious, but nv50 has detached drm_edid_to_eld() from the drm_add_edid_modes() call.

Call drm_edid_to_eld() from drm_add_edid_modes() to fill in the ELD automatically. There's no harm in doing this for connectors that do not support audio. Reviewed-by:

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:

drm_fb_helper is *the* way of doing fbdev emulation so add a pointer to struct drm_device. This makes it possible to add callback helpers for .last_close and .output_poll_changed further reducing fbdev emulation footprint in drivers.

VC4's DSI1 has a bug where the AXI connection is broken for 32-bit writes from the CPU, so we use the DMA engine to DMA 32-bit values into registers instead. That sleeps, so we can't do it from the top half. As a solution, use an interrupt thread so that all our writes happen when sleeping is is allowed. v2: Use IRQF_ONESHOT (suggested by Boris) v3: Style nitpicks. Signed-off-by:

This ioctl will allow us to purge inactive userspace buffers when the system is running out of contiguous memory. For now, the purge logic is rather dumb in that it does not try to release only the amount of BO needed to meet the last CMA alloc request but instead purges all objects placed in the purgeable pool as soon as we experience a CMA allocation failure. Note that the in-kernel BO cache is always purged before the purgeable cache because those objects are known to be unused while objects marked as purgeable by a userspace application/library might have to be restored when they are marked back as unpurgeable, which can be expensive.
