Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit.
This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot.

Sound Mega-commit. Expect further cleanup until code freeze.
For a slightly thorough explaination, please refer to [1] http://people.freebsd.org/~ariff/SOUND_4.TXT.html .
Summary of changes includes:
1 Volume Per-Channel (vpc). Provides private / standalone volume control unique per-stream pcm channel without touching master volume / pcm. Applications can directly use SNDCTL_DSP_[GET|SET][PLAY|REC]VOL, or for backwards compatibility, SOUND_MIXER_PCM through the opened dsp device instead of /dev/mixer. Special "bypass" mode is enabled through /dev/mixer which will automatically detect if the adjustment is made through /dev/mixer and forward its request to this private volume controller. Changes to this volume object will not interfere with other channels.
Requirements: - SNDCTL_DSP_[GET|SET][PLAY|REC]_VOL are newer ioctls (OSSv4) which require specific application modifications (preferred). - No modifications required for using bypass mode, so applications like mplayer or xmms should work out of the box.
Kernel hints: - hint.pcm.%d.vpc (0 = disable vpc).
Kernel sysctls: - hw.snd.vpc_mixer_bypass (default: 1). Enable or disable /dev/mixer bypass mode. - hw.snd.vpc_autoreset (default: 1). By default, closing/opening /dev/dsp will reset the volume back to 0 db gain/attenuation. Setting this to 0 will preserve its settings across device closing/opening. - hw.snd.vpc_reset (default: 0). Panic/reset button to reset all volume settings back to 0 db. - hw.snd.vpc_0db (default: 45). 0 db relative to linear mixer value.
2 High quality fixed-point Bandlimited SINC sampling rate converter, based on Julius O'Smith's Digital Audio Resampling - http://ccrma.stanford.edu/~jos/resample/. It includes a filter design script written in awk (the clumsiest joke I've ever written) - 100% 32bit fixed-point, 64bit accumulator. - Possibly among the fastest (if not fastest) of its kind. - Resampling quality is tunable, either runtime or during kernel compilation (FEEDER_RATE_PRESETS). - Quality can be further customized during kernel compilation by defining FEEDER_RATE_PRESETS in /etc/make.conf.
Kernel sysctls: - hw.snd.feeder_rate_quality. 0 - Zero-order Hold (ZOH). Fastest, bad quality. 1 - Linear Interpolation (LINEAR). Slightly slower than ZOH, better quality but still does not eliminate aliasing. 2 - (and above) - Sinc Interpolation(SINC). Best quality. SINC quality always start from 2 and above.
Rough quality comparisons: - http://people.freebsd.org/~ariff/z_comparison/
3 Bit-perfect mode. Bypasses all feeder/dsp effects. Pure sound will be directly fed into the hardware.
4 Parametric (compile time) Software Equalizer (Bass/Treble mixer). Can be customized by defining FEEDER_EQ_PRESETS in /etc/make.conf.
5 Transparent/Adaptive Virtual Channel. Now you don't have to disable vchans in order to make digital format pass through. It also makes vchans more dynamic by choosing a better format/rate among all the concurrent streams, which means that dev.pcm.X.play.vchanformat/rate becomes sort of optional.
6 Exclusive Stream, with special open() mode O_EXCL. This will "mute" other concurrent vchan streams and only allow a single channel with O_EXCL set to keep producing sound.
Other Changes: * most feeder_* stuffs are compilable in userland. Let's not speculate whether we should go all out for it (save that for FreeBSD 16.0-RELEASE). * kobj signature fixups, thanks to Andriy Gapon <avg@freebsd.org> * pull out channel mixing logic out of vchan.c and create its own feeder_mixer for world justice. * various refactoring here and there, for good or bad. * activation of few more OSSv4 ioctls() (see [1] above). * opt_snd.h for possible compile time configuration: (mostly for debugging purposes, don't try these at home) SND_DEBUG SND_DIAGNOSTIC SND_FEEDER_MULTIFORMAT SND_FEEDER_FULL_MULTIFORMAT SND_FEEDER_RATE_HP SND_PCM_64 SND_OLDSTEREO
Manual page updates are on the way.

Remove unit2minor() use from kernel code.
When I changed kern_conf.c three months ago I made device unit numbers equal to (unneeded) device minor numbers. We used to require bitshifting, because there were eight bits in the middle that were reserved for a device major number. Not very long after I turned dev2unit(), minor(), unit2minor() and minor2unit() into macro's. The unit2minor() and minor2unit() macro's were no-ops.
We'd better not remove these four macro's from the kernel, because there is a lot of (external) code that may still depend on them. For now it's harmless to remove all invocations of unit2minor() and minor2unit().

Update snd_emu10kx driver with recent perforce changes (and few other changes too).
(without any real order)
1. Use device_get_nameunit for mutex naming 2. Add timer for low-latency playback 3. Move most mixer controls from sysctls to mixer(8) controls. This is a largest part of this patch. 4. Add analog/digital switch (as a temporary sysctl) 5. Get back support for low-bitrate playback (with help of (2)) 6. Change locking for exclusive I/O. Writing to non-PTR register is almost safe and does not need to be ordered with PTR operations. 7. Disable MIDI until we get it to detach properly and fix memory managment problems. 8. Enable multichannel playback by default. It is as stable as single-channel mode. Multichannel recording is still an experimental feature. 9. Multichannel options can be changed by loader tunables. 10. Add a way to disable card from a loader tunable. 11. Add new PCI IDs. 12. Debugger settings are loader tunables now. 14. Remove some unused variables. 15. Mark pcm sub-devices MPSAFE. 16. Partially revert (bus_setup_intr -> snd_setup_intr) since it need to be done independently

Despite several examples in the kernel, the third argument of sysctl_handle_int is not sizeof the int type you want to export. The type must always be an int or an unsigned int.
Remove the instances where a sizeof(variable) is passed to stop people accidently cut and pasting these examples.
In a few places this was sysctl_handle_int was being used on 64 bit types, which would truncate the value to be exported. In these cases use sysctl_handle_quad to export them and change the format to Q so that sysctl(1) can still print them.

MFp4 (114068): Use bus_get_dma_tag() to obtain the parent DMA tag to make the drivers a little bit more non-ia32/amd64 friendly.
There is no man page for bus_get_dma_tag, so this is modelled after rev. 1.62 of src/sys/dev/sound/pci/es137x.c by marius.

Extend the emu10kx driver. With the words of the author: ---snip--- New features: 1. Optional multichannel recording (32 channels on Live!, 64 channels on Audigy).
All channels are 16bit/48000Hz/mono, format is fixed. Half of them are copied from sound output, another half can be used to record any data from DSP. What should be recorded is hardcoded in DSP code. In this version it records dummy data, but can be used to record all DSP inputs, for example..
Because there are no support of more-than-stereo sound streams multichannell stream is presented as one 32(64)*48000 Hz 16bit mono stream.
Channel map:
SB Live! (4.0/5.1) offset (words) substream 0x00 Front L 0x01 Front R 0x02 Digital Front L 0x03 Digital Front R 0x04 Digital Center 0x05 Digital Sub 0x06 Headphones L 0x07 Headphones R 0x08 Rear L 0x09 Rear R 0x0A ADC (multi-rate recording) L 0x0B ADC (multi-rate recording) R 0x0C unused 0x0D unused 0x0E unused 0x0F unused 0x10 Analog Center (Live! 5.1) / dummy (Live! 4.0) 0x11 Analog Sub (Live! 5.1) / dummy (Live! 4.0) 0x12..-0x1F dummy

Fixes: 1. Do not assign negative values to variables used to index emu_cards array. This array was never accessed when index is negative, but Alexander (netchild@) told me that Coverity does not like it. After this change emu_cards[0] should never be used to identify valid sound card. 2. Fix off-by-one errors in interrupt manager. Add more checks there. 3. Fixes to sound buffering code now allows driver to use large playback buffers. 4. Fix memory allocation bug when multichannel recording is not enabled. 5. Fix interrupt timeout when recording with low bitrate (8kHz).
Hardware: 1. Add one more known Audigy ZS card to list. Add two cards with PCI IDs betwen old known cards and new one.
Other changes: 1. Do not use ALL CAPS in messages.
Incomplete code: 1. Automute S/PDIF when S/PDIF signal is lost.
Tested on i386 only, gcc 3.4.6 & gcc41/gcc42 (syntax only). ---snip---
This commits enables a little bit of debugging output when the driver is loaded as a module. I did a cross-build test for amd64.
The code has some style issues, this will be addressed later.
The multichannel recording part is some work in progress to allow playing around with it until the generic sound code is better able to handle multichannel streams.
This is supposed to fix CID: 171187 Found by: Coverity Prevent

"Workaround for sound lag in current snd_emu10kx driver. Real problem is interaction between in-kernel sound buffer handling and hardware. With small buffer, there are times when both harwdare reads and kernel writes to the same buffer (it is only visible on slow machines, i think). I'm digging in channel.c and buffer.c to find a solution that allow use of large hardware buffers without sound lags - hardware can handle buffers up to 32Mb."
