2021-02-25The firmware replaces the last 32-bit on RAM with a shared DRAM address.patrick1-2/+8
While the for-loop checks that thie value has changed since we wrote to it, the timeout-condition checked for non-zero, which is wrong. This means that we didn't realize the firmware wasn't started. While there, make sure the shared DRAM address is inside the chip's address space.

2021-02-23timecounting: use C99-style initialization for all timecounter structscheloha6-39/+53
The timecounter struct is large and I think it may change in the future. Changing it later will be easier if we use C99-style initialization for all timecounter structs. It also makes reading the code a bit easier. For reasons I cannot explain, switching to C99-style initialization sometimes changes the hash of the resulting object file, even though the resulting struct should be the same. So there is a binary change here, but only sometimes. No behavior should change in either case. I can't compile-test this everywhere but I have been staring at the diff for days now and I'm relatively confident this will not break compilation. Fingers crossed. ok gnezdo@

2021-02-16Enable multiple opens of a video(4) device as described in the V4L2mglocker1-30/+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@
