The default volume of 65535 is too high. Make is something smaller. Note that this _only_ changes the default value. Specifically, there are no scaling or other more intrusive changes here. I'm just sick of constantly having to reduce the volume every time I plug in and test the device! (And unfortunately we can't do a better fix like scaling the volume so that 65535 makes sense because doing so will screw up any app - like MythTV - which expects the old scaling.) Too bad V4L controls don't have better defined ranges. Signed-off-by:

Trying to temporarily check that the stream is not claimed during open of the radio device is at best a race condition. What's to stop another app from claiming the stream anyway the instant after the check is done? The implementation for this was dicey anyway. So it's removed. The only "price" for this is that if /dev/radioX is opened while streaming video, then the video stream is just going to switch to radio mode anyway. If a user does this, he gets what he expects...

Separate track radio versus tv frequency so that when we switch modes we can also switch to a sane frequency appropriate for the mode. Also implement logic to automate mode switching in certain cases. Signed-off-by:

Frequency units in V4L2 are apparently different when in radio mode compared to tv mode. Why? Who knows. This change adapts the driver appropriately - so that internally we always only deal in Hz and don't have to muck with craziness like this. Signed-off-by:

A conversion from Hz to V4L frequency units was accidentally removed by an earlier change. Restore it. Signed-off-by:

We can't allocate v4l device structures in a block, since the v4l core governs when each device actually gets freed. This bug was introduced as part of the core radio implementation. Fix it. Signed-off-by:

The initial radio implementation used different units for tuning when in radio mode. This changes everything to Hz. Signed-off-by:

Use separate enum for get/store of minor number; we want pvr2_config to go away eventually and since it really means something different, don't use it here Signed-off-by:

The "main" V4L2 interface patch. This is yet very incomplete, incorrect and probably inappropriate for inclusion as-is, but at least with this I 'm able to tune and play radio through a V4L2 program (pvr-radio.c, a "thumb" version of ivtv-radio.c with just the essentials). Therefore, it kinda gives an idea of what is needed to support this, hm, interface (partly used also by e.g., kradio). Please point out any mistakes on this code. I 'm sure I 'm messing up some struct initialization somewhere but currently I 'm too lazy to actually think this through until I complete the functionality (e.g., handle the VIDIOC_S_STD, ENUMINPUT, etc ioctls appropriately).

Add (and expose) a new function, pvr2_channel_check_stream_no_lock(), in pvrusb2-context.c. This is hopefully the last V4L2 interface related patch to change anything outside pvrusb2-v4l2.c. We need this to implement the open() for the radio device. The reason is that within the *enter_context() section of open() we need to ensure nobody is streaming and if we cannot, we should cleanup after ourselves and return -EBUSY. We cannot just use claim_stream() because: 1) That would cause a deadlock trying to re-acquire the context lock 2) We only need to ensure that nobody is streaming. We don't need to actually acquire the stream. Again, this is a kinda ugly patch. Feel free to improve. Signed-off-by: -

This is the first patch in preparation of the V4L2/IVTV radio interface. It does away with the assumption of only one minor per device. It also adds a file to show the radio minor as well. This can be useful for a program like pvr-radio.c (when it grows up), since this way it can search for the minor of the /dev/radioX device it opened and use the video minor of the same driver instance to get to the actual stream. The implementation looks kinda ugly. Feel free to improve (that is the reason behind separate patches anyway). Signed-off-by:

In the previous patch we exploited the get_{min,max}_value facility to adjust min/max allowable frequencies on the fly, depending on tuner mode. Unfortunately, this facility was not used inside the *sym_to_val() function that translates what we echo to sysfs, which means we got an -ERANGE despite asking for a frequency between what we read to be min/max. This patch corrects this small omission. Signed-off-by: -

This is the logic that: a) Ensures /sys/class/pvrusb2/sn-*/ctl_frequency/{max,min}_val are "automagically" reset to sane values on each mode change. b) Allows tuning to a radio frequency by something like: echo `perl -e "print int(94.9*16000 + 0.5)"` \ > /sys/class/pvrusb2/sn-*/ctl_input/cur_val The trick was to take advantage of the already existing .get_{min,max}_value function pointers in pvr2_ctrl, to "dynamically override" the hardcoded values for min/max frequency at runtime. For a moment I thought to dispose of the hardcoded MIN/MAX_FREQ and use the hirange/lowrange fields of the v4l2_tuner struct instead, but then I see that tuner-core.c kinda hardcodes these as well, so I decided to not bother.

This is the logic that supports switching modes via e.g., echo radio > /sys/class/pvrusb2/sn-*/ctl_input/cur_val. To do the mode switching we need to: a) broadcast AUDC_SET_RADIO and b) issue the CX2341X_ENC_MUTE_VIDEO command to the encoder. The first is done by adding a new pvr2_i2c_op and having it trigger on input change, the second by adding this command in pvr2_encoder_start() and requesting an encoder restart on input change by setting stale_subsys_mask appropriately. The clues about AUDC_SET_RADIO and CX2341X_ENC_MUTE_VIDEO were kindly provided by Hans Verkuil on the pvrusb2 mailing list. The idea to implement mode switching this way (on input change) is due to Mike Isely. Why AUDC_SET_RADIO/VIDIOC_S_STD are used for switching? I can 't be sure, but I think this can be traced to a cornell student being the first to implement radio support in ivtv "as a different standard". I think the rest just evolved from there (it 's in the ivtv ML archives). Signed-off-by:

There are several potential troubles on vivi waitqueue code: - Watchdog timer should be reset at every received frame; - Watchdog timer should be reset at the beginning of vivi_thread(); - Checks for errors when creating a newer thread with kernel_thread(); - Wake up vivi_thread() after creating it.

If for some reason vivi_thread() fails, vivi will suffer an OOPS at thread stop code, since waitqueue wouldn't be properly initializated. Signed-off-by: -
