Many thanks to Howard Kim for providing - * contacts and hardware. Honorable mention goes to Eric - * Brombaugh for all sorts of things. 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.

The core of the - * chip is the 'assp', the custom ESS dsp that runs the show. It has - * a small amount of code and data ram. ESS drops binary dsp code images - * on our heads, but we don't get to see specs on the dsp. - * - * The constant piece of code on the dsp is the 'kernel'. It also has a - * chunk of the dsp memory that is statically set aside for its control - * info. This is the KDATA defines in maestro3.h. Part of its core - * data is a list of code addresses that point to the pieces of DSP code - * that it should walk through in its loop. These other pieces of code - * do the real work. The kernel presumably jumps into each of them in turn. - * These code images tend to have their own data area, and one can have - * multiple data areas representing different states for each of the 'client - * instance' code portions. There is generally a list in the kernel data - * that points to the data instances for a given piece of code. - * - * We've only been given the binary image for the 'minisrc', mini sample - * rate converter. This is rather annoying because it limits the work - * we can do on the dsp, but it also greatly simplifies the job of managing - * dsp data memory for the code and data for our playing streams :). We - * statically allocate the minisrc code into a region we 'know' to be free - * based on the map of the binary kernel image we're loading. We also - * statically allocate the data areas for the maximum number of pcm streams - * we can be dealing with. This max is set by the length of the static list - * in the kernel data that records the number of minisrc data regions we - * can have. Thats right, all software dsp mixing with static code list - * limits. Rock. - * - * How sound goes in and out is still a relative mystery. It appears - * that the dsp has the ability to get input and output through various - * 'connections'. To do IO from or to a connection, you put the address - * of the minisrc client area in the static kernel data lists for that - * input or output. so for pcm -> dsp -> mixer, we put the minisrc data - * instance in the DMA list and also in the list for the mixer. I guess - * it Just Knows which is in/out, and we give some dma control info that - * helps. There are all sorts of cool inputs/outputs that it seems we can't - * use without dsp code images that know how to use them. - * - * So at init time we preload all the memory allocation stuff and set some - * system wide parameters. When we really get a sound to play we build - * up its minisrc header (stream parameters, buffer addresses, input/output - * settings). Then we throw its header on the various lists. We also - * tickle some KDATA settings that ask the assp to raise clock interrupts - * and do some amount of software mixing before handing data to the ac97. - * - * Sorry for the vague details. Feel free to ask Eric or myself if you - * happen to be trying to use this driver elsewhere.
