Fix IRQ flags for PCI devices. The shared IRQs for PCI devices shouldn't be allocated with IRQF_DISABLED. Also, when MSI is enabled, IRQF_SHARED shouldn't be used. The patch removes unnecessary cast in request_irq and free_irq, too. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

* azt3328.c - driver for Aztech AZF3328 based soundcards (e.g. PCI168).
|
|
* 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),
|
|
* found in a Fujitsu-Siemens PC ("Cordant", aluminum case).
|
|
* Other versions are:
|
|
* PCI168 A(W), sub ID 1800
|
|
* PCI168 A/AP, sub ID 8000
|
|
* Please give me feedback in case you try my driver with one of these!!

*
|
|
* NOTES
|
|
* Since Aztech does not provide any chipset documentation,
|
|
* even on repeated request to various addresses,
|
|
* and the answer that was finally given was negative
|
|
* (and I was stupid enough to manage to get hold of a PCI168 soundcard
|
|
* 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 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)
|
|
* 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 (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
|
|
* - single chip low cost solution (128 pin QFP)
|
|
* - supports programmable Sub-vendor and Sub-system ID
|
|
* 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
|
|
* people with the same chipset.
|
|
* Possible remedies:
|
|
* - plug card into a different PCI slot, preferrably one that isn't shared
|
|
* too much (this helps a lot, but not completely!)
|
|
* - get rid of PCI VGA card, use AGP instead
|
|
* - upgrade or downgrade BIOS
|
|
* - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX)
|
|
* Not too helpful.
|
|
* - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
|
|
*
|
|
* BUGS
|
|
* - full-duplex might *still* be problematic, not fully tested recently
|
|
*
|
|
* TODO
|
|
* - test MPU401 MIDI playback etc.
|
|
* - 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)
