Louis Kuo	e6a59da61e	ANDROID: media: v4l2-core: Fix deadlock in vendor hook ... The vendor hook functions we implemented will invoke callback functions which have do some sleep or spinlock operations and have risk of deadlock due to preemption disabled of normal vendor hook function. So we have to use restricted vendor hook function instead. Due to KMI freeze we could not change the existing hooks. trace_android_rvh_media_device_setup_link =>invoke setup_link, link_notify callback trace_android_rvh_v4l2subdev_set_xxx =>invoke set_xxx callback Bug: 193870284 Signed-off-by: Louis Kuo <louis.kuo@mediatek.com> Change-Id: I94fe2e112b6c3d9ac5177abb30a99b7007068f7e	2021-07-21 13:05:27 +00:00
Louis Kuo	f1a161b019	ANDROID: media: v4l2-core: extend the v4l2 format to support request ... This patch is to extend the related interface to support the request-based operations. We use extension fields in the parameters of MEDIA_IOC_SETUP_LINK, VIDIOC_S_FMT, VIDIOC_SUBDEV_S_SELECTION, VIDIOC_SUBDEV_S_FMT as request fd. The driver uses media_request_get_by_fd() to retrieve the media request and save the pending change in it, so that we can apply the pending change in req_queue() callback then. Besides, We also add three vendor hook functions to handle related changes in v4l2-framework.
