Purely conjecture, but I think the original locking inversion with the legacy page flip code between flipping and ttm's bo move function shoudn't exist anymore with atomic: With atomic the bo pinning and actual modeset commit is completely separated in the code patsh.

Fix set but not used warnings by introducing no_printk variants for the internal logging system for this driver. Fix a new warning that popped up now that logging was checked for correct printf format strings. A more invasive fix had been to replace all the internal logging with standard logging primitives - thats for another day. v2: - Update subject (Lee) Signed-off-by:

Fix warning about variable that is asssigned a value but never used. The variable was indeed never used so delete it. Keep the call to radeon_probe_i2c_connector() as it may have side-effects. It is unlikely but I could not verify that is was safe to drop the call. Signed-off-by:

Mapping the imported pages of a DMA-buf into an userspace process doesn't work as expected. But we have reoccurring requests on this approach, so split the functions for this and document that dma_buf_mmap() needs to be used instead. v2: split it into two functions v3: rebased on latest changes v4: update commit message a bit Signed-off-by:

The new GEM object function drm_gem_cma_mmap() sets the VMA flags and offset as in the old implementation and immediately maps in the buffer's memory pages. Changing CMA helpers to use the GEM object function allows for the removal of the special implementations for mmap and gem_prime_mmap callbacks. The regular functions drm_gem_mmap() and drm_gem_prime_mmap() are now used. Signed-off-by:

Add support for the BOE NV110WTM-N61 panel. The EDID lists two modes (one for 60 Hz refresh rate and one for 40 Hz), so we'll list both of them here. Note that the panel datasheet requires 80 ms between HPD asserting and the backlight power being turned on. We'll use the new timing constraints structure to do this cleanly. This assumes that the backlight will be enabled _after_ the panel enable finishes. This is how it works today and seems a sane assumption. Signed-off-by:

Douglas Anderson authored
On the panel I'm looking at, there's an 80 ms minimum time between HPD being asserted by the panel and setting the backlight enable GPIO. While we could just add an 80 ms "enable" delay, this is not ideal. Link training is allowed to happen in parallel with this delay so the fixed 80 ms delay over-delays. We'll support this by logging the time at the end of prepare and then delaying in enable if enough time hasn't passed. Signed-off-by:

It is believed that all of the current users of the "unprepare" delay don't actually need to wait the amount of time specified directly in the unprepare phase. The purpose of the delay that's specified is to allow the panel to fully power off so that we don't try to power it back on before it's managed to full power down. Let's use this observation to avoid the fixed delay that we currently have. Instead of delaying, we'll note the current time when the unprepare happens. If someone then tries to prepare the panel later and not enough time has passed, we'll do the delay before starting the prepare phase. Signed-off-by:

When I run: scripts/kernel-doc -rst drivers/gpu/drm/panel/panel-simple.c I see that several of the kernel-doc entries aren't showing up because they don't specify the full path down the hierarchy. Let's fix that and also move to inline kernel docs. Signed-off-by:

The NULL checking isn't done consistently in this function and it leads to a static checker warning: drivers/gpu/drm/kmb/kmb_drv.c:561 kmb_pm_suspend() error: we previously assumed 'drm' could be null (see line 559) Fortunately "drm" cannot be NULL at this point so the check can just be removed.
