* Driver CA0106 chips . e . g . Sound Blaster Audigy LS and Live 24 bit
2005-05-27 22:07:23 +02:00
* Version : 0.0 .23
2005-04-17 00:20:36 +02:00
*
* FEATURES currently supported :
* Front , Rear and Center / LFE .
* Surround40 and Surround51 .
* Capture from MIC an LINE IN input .
* SPDIF digital playback of PCM stereo and AC3 / DTS works .
* ( One can use a standard mono mini - jack to one RCA plugs cable .
* or one can use a standard stereo mini - jack to two RCA plugs cable .
* Plug one of the RCA plugs into the Coax input of the external decoder / receiver . )
* ( In theory one could output 3 different AC3 streams at once , to 3 different SPDIF outputs . )
* Notes on how to capture sound :
* The AC97 is used in the PLAYBACK direction .
* The output from the AC97 chip , instead of reaching the speakers , is fed into the Philips 1361 T ADC .
* So , to record from the MIC , set the MIC Playback volume to max ,
* unmute the MIC and turn up the MASTER Playback volume .
* So , to prevent feedback when capturing , minimise the " Capture feedback into Playback " volume .
*
* The only playback controls that currently do anything are : -
* Analog Front
* Analog Rear
* Analog Center / LFE
* SPDIF Front
* SPDIF Rear
* SPDIF Center / LFE
*
* For capture from Mic in or Line in .
* Digital / Analog ( switch must be in Analog mode for CAPTURE . )
*
* CAPTURE feedback into PLAYBACK
*
* Changelog :
* Support interrupts per period .
* Removed noise from Center / LFE channel when in Analog mode .
* Rename and remove mixer controls .
* 0.0 .6
* Use separate card based DMA buffer for periods table list .
* 0.0 .7
* Change remove and rename ctrls into lists .
* 0.0 .8
* Try to fix capture sources .
* 0.0 .9
* Fix AC3 output .
* Enable S32_LE format support .
* 0.0 .10
* Enable playback 48000 and 96000 rates . ( Rates other that these do not work , even with " plug:front " . )
* 0.0 .11
* Add Model name recognition .
* 0.0 .12
* Correct interrupt timing . interrupt at end of period , instead of in the middle of a playback period .
* Remove redundent " voice " handling .
* 0.0 .13
* Single trigger call for multi channels .
* 0.0 .14
* Set limits based on what the sound card hardware can do .
* playback periods_min = 2 , periods_max = 8
* capture hw constraints require period_size = n * 64 bytes .
* playback hw constraints require period_size = n * 64 bytes .
* 0.0 .15
* Minor updates .
* 0.0 .16

* 0.0 .17
* Add support for SB0410 and SB0413 .
* 0.0 .18
* Modified Copyright message .
* 0.0 .19
* Finally fix support for SB Live 24 bit . SB0410 and SB0413 .
* The output codec needs resetting , otherwise all output is muted .
* 0.0 .20
* Merge " pci_disable_device(pci); " fixes .
* 0.0 .21
* Add 4 capture channels . ( SPDIF only comes in on channel 0. )
* Add SPDIF capture using optional digital I / O module for SB Live 24 bit . ( Analog capture does not yet work . )
* 0.0 .22
* Add support for MSI K8N Diamond Motherboard with onboard SB Live 24 bit without AC97 . From kiksen , bug # 901
2005-05-27 22:07:23 +02:00
* 0.0 .23
* Implement support for Line - in capture on SB Live 24 bit .
2005-04-17 00:20:36 +02:00

* BUGS :
* Some stability problems when unloading the snd - ca0106 kernel module .
* - -
*
* TODO :
* 4 Capture channels , only one implemented so far .
* Other capture rates apart from 48 khz not implemented .

[ALSA] Remove redundant NULL checks before kfree

Checking a pointer for NULL before calling kfree() on it is redundant,
kfree() deals with NULL pointers just fine.
This patch removes such checks from sound/
This patch also makes another, but closely related, change.
It avoids casting pointers about to be kfree()'ed.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.
