[RFC PATCH 2/9] media: request: add generic queue

Add a generic request queue that supports most use-case and should be usable as-is by drivers without special hardware features. The generic queue stores the requests into a FIFO list and executes them sequentially. Signed-off-by: Alexandre Courbot ---

[PATCH 04/10] media: rc: bang in ir_do_keyup

rc_keydown() can be called from interrupt context, by e.g. an rc scancode driver. Since commit b2c96ba352b5 ("media: cec: move cec autorepeat handling to rc-core"), the del_timer_sync() call is not happy about being called in interrupt connect. del_timer() will suffice. WARNING: CPU: 0 PID: 0 at

[PATCH 08/10] media: lirc: no need to recalculate duration

This is code existed for when drivers would send less than the whole buffer; no driver does this any more, so this is redundant. Drivers should return -EINVAL if they cannot send the entire buffer. Signed-off-by: Sean Young --- drivers/media/rc/lirc_dev.c | 10 +- 1 file

[PATCH 05/10] media: lirc: when transmitting scancodes, block until transmit is done

The semantics for lirc IR transmit with raw IR is that the write call should block until the IR is transmitted. Some drivers have no idea when this actually is (e.g. mceusb), so there is a wait. This is useful for userspace, as it might want to send a IR button press, a gap of a predefined number

Hi Hans, I would like to get your opinion on this patch. Do you think it makes sense to: 1. add limited support for USERPTR and DMA-buf import? (limited means driver will accept setting buffer pointer/fd only once after reqbufs for each buffer index) 2. add a V4L2 device flag to let
