* Enable multiple opens of a video(4) device as described in the V4L2mglocker2021-02-161-30/+109
| | | | | | | | | | | | | | | | | | | | | | | specification: https://www.kernel.org/doc/html/v5.10/userspace-api/media/v4l/open.html#f1 The discussion has been started by jca@, who has implemented this behavior recently, but limited to the same process. This diff extends this behavior to any process. The first process which opens a stream will become the device owner. Other processes are still allowed to call certain ioctls, but none which are related to the start/stop of a stream, or manipulation of the streaming buffers. At the moment only VIDIOC_G_CTRL and VIDIOC_S_CTRL are supported to be called by non- device owner processes, which should be extended further in the future. There is no additional kernel locking implemented at the moment, since video(4) already runs under the KERNEL_LOCK(), which we expect to be sufficient for now (as discussed with claudio@). A lot of improvement input received from anton@. ok anton@

| | | | | | | | | | | | - Sync comments with NetBSD including locking details. - Remove superfluous parenthesis and spaces. - Add brackets, even if questionable, to reduce diff with NetBSD - Use for (;;) instead of while(1) - Rename a variable from 'result' into 'error'. - Move uvm_fault() and uvm_fault_upper_lookup() - Add an locking assert in uvm_fault_upper_lookup() ok tb@, mlarkin@

| | | | | | | | | Set up the DMAC filter in one go instead of doing it separately for unicast and multicast DMACs. This attempts to make the code a little more readable. The setup should now run a bit faster as well because it now does fewer register accesses. Tested on CN5020, CN6120 and CN7130.

* Leave out gp initialization from kernel entry on mips64visa2021-02-119-24/+8
| | | | | | | | | On OpenBSD/mips64, the kernel is compiled with -mno-abicalls. This disables gp-relative addressing and essentially makes gp a spare register in the kernel. Hence it is unnecessary to initialize gp when entering the kernel. The _gp symbol is not needed either. Suggested by miod@
