gpu: ipu-v3: Fix i.MX IPU-v3 offset calculations for (semi)planar U/V formats

2021-08-16T13:05:22Z

Video captured in 1400x1050 resolution (bytesperline aka stride = 1408 bytes) is invalid. Fix it. Signed-off-by: Krzysztof Halasa Link: https://lore.kernel.org/r/m3y2bmq7a4.fsf@t19.piap.pl [p.zabel@pengutronix.de: added "gpu: ipu-v3:" prefix to commit description] Signed-off-by: Philipp Zabel

drm/imx: Add 8 pixel alignment fix

2021-05-10T14:39:54Z

Some standard resolutions like 1366x768 do not work properly with i.MX6 SoCs, since the horizontal resolution needs to be aligned to 8 pixels (so 1360x768 or 1368x768 would work). This patch allocates framebuffers allocated to 8 pixels. The extra time required to send the extra pixels are removed from the blank time. In order to expose the correct display size to userspace, the stride is increased without increasing the width. Without this patch systems with this display resolution hang indefinitely during boot up.

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

gpu: ipu-v3: image-convert: Wait for all EOFs before completing a tile

2020-07-20T13:16:05Z

Use a bit-mask of EOF irqs to determine when all required idmac channel EOFs have been received for a tile conversion, and only do tile completion processing after all EOFs have been received. Otherwise it was found that a conversion would stall after the completion of a tile and the start of the next tile, because the input/read idmac channel had not completed and entered idle state, thus locking up the channel when attempting to re-start it for the next tile.
