[PATCH] The scheduled removal of some OSS drivers
This patch contains the scheduled removal of OSS drivers that:
- have ALSA drivers for the same hardware without known regressions and
- whose Kconfig options have been removed in 2.6.17.

Best regards to the - * proprietors of Hack Central for fine lodging. - * - * Supported devices: - * /dev/dsp0-3 standard /dev/dsp device, (mostly) OSS compatible - * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible - * - * Hardware Description - * - * A working Maestro setup contains the Maestro chip wired to a - * codec or 2. In the Maestro we have the APUs, the ASSP, and the - * Wavecache. The APUs can be though of as virtual audio routing - * channels. They can take data from a number of sources and perform - * basic encodings of the data. The wavecache is a storehouse for - * PCM data. Typically it deals with PCI and interracts with the - * APUs. The ASSP is a wacky DSP like device that ESS is loth - * to release docs on. Thankfully it isn't required on the Maestro - * until you start doing insane things like FM emulation and surround - * encoding. The codecs are almost always AC-97 compliant codecs, - * but it appears that early Maestros may have had PT101 (an ESS - * part?) wired to them. The only real difference in the Maestro - * families is external goop like docking capability, memory for - * the ASSP, and initialization differences. - * - * Driver Operation - * - * We only drive the APU/Wavecache as typical DACs and drive the - * mixers in the codecs. There are 64 APUs. We assign 6 to each - * /dev/dsp? device. 2 channels for output, and 4 channels for - * input. - * - * Each APU can do a number of things, but we only really use - * 3 basic functions. For playback we use them to convert PCM - * data fetched over PCI by the wavecahche into analog data that - * is handed to the codec. One APU for mono, and a pair for stereo. - * When in stereo, the combination of smarts in the APU and Wavecache - * decide which wavecache gets the left or right channel. - * - * For record we still use the old overly mono system. For each in - * coming channel the data comes in from the codec, through a 'input' - * APU, through another rate converter APU, and then into memory via - * the wavecache and PCI. If its stereo, we mash it back into LRLR in - * software. The pass between the 2 APUs is supposedly what requires us - * to have a 512 byte buffer sitting around in wavecache/memory. - * - * The wavecache makes our life even more fun. First off, it can - * only address the first 28 bits of PCI address space, making it - * useless on quite a few architectures. Secondly, its insane. - * It claims to fetch from 4 regions of PCI space, each 4 meg in length. - * But that doesn't really work. You can only use 1 region. So all our - * allocations have to be in 4meg of each other. Booo. Hiss. - * So we have a module parameter, dsps_order, that is the order of - * the number of dsps to provide. All their buffer space is allocated - * on open time. The sonicvibes OSS routines we inherited really want - * power of 2 buffers, so we have all those next to each other, then - * 512 byte regions for the recording wavecaches. This ends up - * wasting quite a bit of memory. The only fixes I can see would be - * getting a kernel allocator that could work in zones, or figuring out - * just how to coerce the WP into doing what we want. - * - * The indirection of the various registers means we have to spinlock - * nearly all register accesses. We have the main register indirection - * like the wave cache, maestro registers, etc. Then we have beasts - * like the APU interface that is indirect registers gotten at through - * the main maestro indirection. Ouch. We spinlock around the actual - * ports on a per card basis. This means spinlock activity at each IO - * operation, but the only IO operation clusters are in non critical - * paths and it makes the code far easier to follow. Interrupts are - * blocked while holding the locks because the int handler has to - * get at some of them :(. The mixer interface doesn't, however. - * We also have an OSS state lock that is thrown around in a few - * places. - * - * This driver has brute force APM suspend support. We catch suspend - * notifications and stop all work being done on the chip. Any people - * that try between this shutdown and the real suspend operation will - * be put to sleep. When we resume we restore our software state on - * the chip and wake up the people that were using it. The code thats - * being used now is quite dirty and assumes we're on a uni-processor - * machine. Much of it will need to be cleaned up for SMP ACPI or - * similar. - * - * We also pay attention to PCI power management now. The driver - * will power down units of the chip that it knows aren't needed. - * The WaveProcessor and company are only powered on when people - * have /dev/dsp*s open. On removal the driver will - * power down the maestro entirely. There could still be - * trouble with BIOSen that magically change power states - * themselves, but we'll see. - * - * History - * v0.15 - May 21 2001 - Marcus Meissner <mm@caldera.de> - * Ported to Linux 2.4 PCI API.
