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).

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.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

vivi.c uses the KM_BOUNCE_READ with local interrupts enabled. This means that if a disk interrupt occurs while vivi.c is using this fixmap slot, the vivi.c driver will, upon return from that interrupt, find that the fixmap slot now points at a different physical page. The net result will probably be rare corruption of disk file contents, because viv.c will now be altering the page which the disk code was recently using. Thanks to Andrew Morton for pointing this.
