* azt3328.c - driver for Aztech AZF3328 based soundcards (e.g. PCI168).
- * Copyright (C) 2002 by Andreas Mohr <hw7oshyuv3001@sneakemail.com>
+ * Copyright (C) 2002, 2005 by Andreas Mohr <andi AT lisas.de>
*
* Framework borrowed from Bart Hartgers's als4000.c.
* Driver developed on PCI168 AP(W) version (PCI rev. 10, subsystem ID 1801),
* in the first place >:-P}),
* I was forced to base this driver on reverse engineering
* (3 weeks' worth of evenings filled with driver work).
- * (and no, I did NOT go the easy way: to pick up a PCI128 for 9 Euros)
+ * (and no, I did NOT go the easy way: to pick up a SB PCI128 for 9 Euros)
*
* The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
* for compatibility reasons) has the following features:
*
* - builtin AC97 conformant codec (SNR over 80dB)
- * (really AC97 compliant?? I really doubt it when looking
- * at the mixer register layout)
+ * Note that "conformant" != "compliant"!! this chip's mixer register layout
+ * *differs* from the standard AC97 layout:
+ * they chose to not implement the headphone register (which is not a
+ * problem since it's merely optional), yet when doing this, they committed
+ * the grave sin of letting other registers follow immediately instead of
+ * keeping a headphone dummy register, thereby shifting the mixer register
+ * addresses illegally. So far unfortunately it looks like the very flexible
+ * ALSA AC97 support is still not enough to easily compensate for such a
+ * grave layout violation despite all tweaks and quirks mechanisms it offers.
* - builtin genuine OPL3
* - full duplex 16bit playback/record at independent sampling rate
* - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
* - game port (legacy address support)
* - built-in General DirectX timer having a 20 bits counter
- * with 1us resolution (FIXME: where is it?)
+ * with 1us resolution (see below!)
* - I2S serial port for external DAC
* - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI
* - supports hardware volume control
* required for Microsoft's logo compliance (FIXME: where?)
* - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
*
+ * Note that this driver now is actually *better* than the Windows driver,
+ * since it additionally supports the card's 1MHz DirectX timer - just try
+ * the following snd-seq module parameters etc.:
+ * - options snd-seq seq_default_timer_class=2 seq_default_timer_sclass=0
+ * seq_default_timer_card=0 seq_client_load=1 seq_default_timer_device=0
+ * seq_default_timer_subdevice=0 seq_default_timer_resolution=1000000
+ * - "timidity -iAv -B2,8 -Os -EFreverb=0"
+ * - "pmidi -p 128:0 jazz.mid"
+ *
* Certain PCI versions of this card are susceptible to DMA traffic underruns
* in some systems (resulting in sound crackling/clicking/popping),
* probably because they don't have a DMA FIFO buffer or so.
* Overview (PCI ID/PCI subID/PCI rev.):
* - no DMA crackling on SiS735: 0x50DC/0x1801/16
* - unknown performance: 0x50DC/0x1801/10
- *
+ * (well, it's not bad on an Athlon 1800 with now very optimized IRQ handler)
+ *
* Crackling happens with VIA chipsets or, in my case, an SiS735, which is
* supposed to be very fast and supposed to get rid of crackling much
* better than a VIA, yet ironically I still get crackling, like many other
* - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
*
* BUGS
- * - when Ctrl-C'ing mpg321, the playback loops a bit
- * (premature DMA playback reset?)
- * - full-duplex sometimes breaks (IRQ management issues?).
- * Once even a spontaneous REBOOT happened!!!
+ * - full-duplex might *still* be problematic, not fully tested recently
*
* TODO
* - test MPU401 MIDI playback etc.
- * - power management (CONFIG_PM). See e.g. intel8x0 or cs4281.
- * This would be nice since the chip runs a bit hot, and it's *required*
- * anyway for proper ACPI power management. In other words: rest
- * assured that I *will* implement this very soon; as soon as Linux 2.5.x
- * has power management that's bugfree enough to work properly on my desktop.
+ * - add some power micro-management (disable various units of the card
+ * as long as they're unused). However this requires I/O ports which I
+ * haven't figured out yet and which thus might not even exist...
+ * The standard suspend/resume functionality could probably make use of
+ * some improvement, too...
* - figure out what all unknown port bits are responsible for
+ * - figure out some cleverly evil scheme to possibly make ALSA AC97 code
+ * fully accept our quite incompatible ""AC97"" mixer and thus save some
+ * code (but I'm not too optimistic that doing this is possible at all)
