Fix W=1 warnings about variables assigned but never used. - One variable is only used when CONFIG_FB_ATY_GENERIC_LCD is defined Fix so variable is only defined with CONFIG_FB_ATY_GENERIC_LCD - Several variables was only assigned by a call to aty_ld_le32(). Drop the variables but keep the call to aty_ld_le32() as it may have unexpected side-effects. v2: - Updated 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:

Douglas Anderson authored
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:

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.

Not technically a problem for ttm, but very likely a driver bug and pretty big time confusing for reviewing code. So warn about it, both at cleanup time (so we catch these for sure) and at pin/unpin time (so we know who's the culprit). Reviewed-by:

It looks like SPARC64 requires FB_ATY_CT to build without errors, so have FB_ATY select FB_ATY_CT if both SPARC64 and PCI are enabled instead of using "default y if SPARC64 && PCI", which is not strong enough to prevent build errors. As it currently is, FB_ATY_CT can be disabled, resulting in build errors: ERROR: modpost: "aty_postdividers" [drivers/video/fbdev/aty/atyfb.ko] undefined!

DCSS supports 90/180/270 degree rotations for Vivante tiled and super-tiled formats. Unfortunately, with the current code, they didn't work properly. This simple patch makes the rotations work by fixing the way the scaler is set up for 90/270 degree rotations. In this particular case, the source width and height need to be swapped since DPR is sending the buffer to scaler already rotated. Also, make sure to allow full rotations for DRM_FORMAT_MOD_VIVANTE_SUPER_TILED. Fixes: 9021c317 ("drm/imx: Add initial support for DCSS on iMX8MQ") Signed-off-by:

Flushing the fbdev's shadow buffer requires vmap'ing the BO memory, which in turn requires pinning the BO. While being pinned, the BO cannot be moved into VRAM for scanout. Consequently, a concurrent modeset operation that involves the fbdev framebuffer would likely fail. Resolve this problem be acquiring the modeset lock of the planes that use the fbdev framebuffer. On non-atomic drivers, also acquire the mode-config lock. This serializes the flushing of the framebuffer with concurrent modeset operations. v2: * only acquire struct drm_fb_helper.lock in damage blitter (Daniel, Christian) Signed-off-by:
