using critcal_enter() and critical_exit() to attempt to replace spl*() calls. The critical section was calling selrecord(), which locks an MTX_DEF mutex, which is not legal in a critical section. Tested by: Stefan Ehmann and "make universe" Approved by: re (scottl)

- Implement selwakeuppri() which allows raising the priority of a

thread being waken up. The thread waken up can run at a priority as high as after tsleep(). - Replace selwakeup()s with selwakeuppri()s and pass appropriate priorities. - Add cv_broadcastpri() which raises the priority of the broadcast threads. Used by selwakeuppri() if collision occurs. Not objected in: -arch, -current

Use PCIR_BAR(x) instead of PCIR_MAPS.

Revision 1.126 broke the interface of the bktr driver's

2003-08-26T16:57:24Z

METEORSSIGNAL ioctl. Applications use this ioctl with the value METEOR_SIG_MODE_MASK (0xFFFF0000, -65536) to reset signal delivery, but revision 1.126 caused the driver to return EINVAL in this case. Interestingly, the same METEORSSIGNAL ioctl in the meteor driver uses 0 to reset signal delivery. This commit allows METEOR_SIG_MODE_MASK as a synonym for 0 in the bktr driver, and restructures the code a bit so that it is otherwise identical between the bktr and meteor drivers.

Use __FBSDID().

Add a overhaul of the soundchip initialization for the MSP34xx chipsets

found only many tv-cards. We currently use more ore less evil hacks (slow_msp_audio sysctl) to configure the various variants of these chips in order to have stereo autodetection work. Nevertheless, this doesn't always work even though it _should_, according to the specs. This is, for example, the case for some popular Hauppauge models sold sold in Germany. However, the Linux driver always worked for me and others. Looking at the sourcecode you will find that the linux-driver uses a very much enhanced approach to program the various msp34xx chipset variants, which is also found in the specs for these chips. This is a port of the Linux MSP34xx code, written by Gerd Knorr , who agreed to re-release his code under a BSD license for this port. A new config option "BKTR_NEW_MSP34XX_DRIVER" is added, which is required to enable the new driver. Otherwise the old code is used. The msp34xx.c file is diff-reduced to the linux-driver to make later modifications easier, thus it doesn't follow style(9) in most cases.
