drm: rcar-du: Repair vblank for DRM page flips using the VSP

2017-08-03T13:17:30+00:00

The driver recently switched from handling page flip completion in the DU vertical blanking handler to the VSP frame end handler to fix a race condition. This unfortunately resulted in incorrect timestamps in the vertical blanking events sent to userspace as vertical blanking is now handled after sending the event. To fix this we must reverse the order of the two operations. The easiest way is to handle vertical blanking in the VSP frame end handler before sending the event. The VSP frame end interrupt occurs approximately 50µs earlier than the DU frame end interrupt, but this should not cause any undue harm. As we need to handle vertical blanking even when page flip completion is delayed, the VSP driver now needs to call the frame end completion callback unconditionally, with a new argument to report whether page flip has completed. With this new scheme the DU vertical blanking interrupt isn't needed anymore, so we can stop enabling it.

v4l: vsp1: Add pipe index argument to the VSP-DU API

2017-07-29T20:46:56+00:00

In the H3 ES2.0 SoC the VSP2-DL instance has two connections to DU channels that need to be configured independently. Extend the VSP-DU API with a pipeline index to identify which pipeline the caller wants to operate on. Signed-off-by: Laurent Pinchart Reviewed-by: Kieran Bingham Acked-by: Mauro Carvalho Chehab

media: platform: davinci: drop VPFE_CMD_S_CCDC_RAW_PARAMS

2017-07-26T10:14:33+00:00

drop VPFE_CMD_S_CCDC_RAW_PARAMS ioctl from dm355/dm644x following reasons: - This ioctl was never in public api and was only defined in kernel header. - The function set_params constantly mixes up pointers and phys_addr_t numbers. - This is part of a 'VPFE_CMD_S_CCDC_RAW_PARAMS' ioctl command that is described as an 'experimental ioctl that will change in future kernels'. - The code to allocate the table never gets called after we copy_from_user the user input over the kernel settings, and then compare them for inequality. - We then go on to use an address provided by user space as both the __user pointer for input and pass it through phys_to_virt to come up with a kernel pointer to copy the data to. This looks like a trivially exploitable root hole. Signed-off-by: Lad, Prabhakar Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec-notifier: small improvements

2017-07-26T09:46:44+00:00

Allow calling cec_notifier_set_phys_addr and cec_notifier_set_phys_addr_from_edid with a NULL notifier, in which case these functions do nothing. Add a cec_notifier_phys_addr_invalidate helper function (the notifier equivalent of cec_phys_addr_invalidate). These changes simplify drm CEC driver support.
