[alsa-devel] [PATCH] ASoC: OMAP: Continue fixing DSP DAI format in McBSP DAI driver
by Jarkko Nikula 22 Oct '08

22 Oct '08

Fix "ASoC: OMAP: Fix DSP DAI format in McBSP DAI driver" was not correct due misunderstanding of DSP_A format and similar error in TLV320AIC33 codec which was used to test the original fix. This patch corrects now DSP_A format in OMAP McBSP DAI driver and is verified with TLV320AIC23 codec that's implementing DSP_A correctly.

[alsa-devel] [PATCH 2.6.28] ALSA: Ensure PXA runtime data is initialised
by Mark Brown 22 Oct '08

22 Oct '08

The rest of the code relies on the runtime data being zero initialised so we need to use kzalloc() to allocate it.

On a related note, it looks to me as if the leading two characters (the manufacturing location) have been erroneously included for E-MU products. You'll see this MA code on some sound cards as well (MASBxxxx) Regards, Tony V.

[alsa-devel] [PATCH] ASoC: OMAP: Fix DSP DAI format in McBSP DAI driver
by Jarkko Nikula 22 Oct '08

22 Oct '08

Fix word clock length which must equal to one bit clock cycle in DSP mode. Surprisingly McBSP is able synchronize into wrong length when it's slave but e.g. TLV320AIC33 codec in slave configuration is outputting some amount of noise if word clock length is longer than one bit clock cycle. Fix also bit clock and frame sync polarities in DSP mode since they are opposite from I2S.

[alsa-devel] help test sbxfi
by William Zumwalt 22 Oct '08

22 Oct '08

I've been very interested in a working driver for the X-Fi for a long time, saw work was finally started, and would like to help test things out. Can someone list where the source is and the steps needed to get this working on linux? Kernel version, which X-Fi card, etc... I'd like to help and follow along if possible.

[alsa-devel] quick question, BT codec???
by John Kacur 22 Oct '08

22 Oct '08

Hello, quick question, both s3c24xx-pcm.c and pxa2xx-pcm.c contain the following comment and code segment, what does the "BT codec" refer to? /* return if this is a bufferless transfer e.g. * codec <--> BT codec or GSM modem -- lg FIXME */ if (!dma) return 0;

[alsa-devel] 20K1 PCI bars, and mode switching info.
by James Courtier-Dutton 22 Oct '08

22 Oct '08

This info should help the current snd-sbxfi driver to actually work with the "Vista compatible" cards that it currently does not work with. I believe the true UAA to 20K1 mode switch code is missing from the current alsa snd-sbxfi driver. PCI BARs UAA mode, or Vista Compatibility mode. BAR0: 16K for UAA 14h BAR1: 2M for 20k1 (low 32 bit) 18h 2M for 20k1 (high 32 bit) 1Ch BAR2: Between 2 and 256M for 20k1 (low 32 bit) 20h Between 2 and 256M for 20k1 (high 32 bit) 24h BAR3: 32 bit I/O for 20K1 20K1 Mode BAR0: 32 bit I/O for 20K1 14h BAR1: 2M for 20k1 (low 32 bit) 18h 2M for 20k1 (high 32 bit) 1Ch BAR2: Between 2 and 256M for 20k1 (low 32 bit) 20h Between 2 and 256M for 20k1 (high 32 bit) 24h "UAA/20K1 mode" and "config space selection" work independently of each other. 1) Configuration space selection: This allows the driver to talk to both the UAA and 20K1 configuration space whichever mode (UAA or 20K1) the card is in. Location: PCI Register 0xA0 for "20K1 Configuration Space Flag" register. Value: 0x12345678 to select 20K1 without BAR0 exposed; Value: 0x87654321 to select 20K1 with BAR0 exposed; (should disable immediately after using.) Value: 0x00000000 to select UAA. 2) UAA/20K1 MODE CHANGE (controls who the bus master is): The "Mode Change" register is located in the UAA configuration space at location offset 0x3FFC. This location stores 4 values in a ring. To switch from 20K1 mode to UAA mode write each DW value: CTLA, CTLZ, CTLL, CTLA. To switch from UAA mode to 20K1 mode write each DW value: CTLX, CTL-, CTLF, CTLi To read the current mode, the 4 value ring may be in any position, so one might read for example: CTLL, CTLA, CTLA, CTLZ At power on, the card is in UAA mode. In UAA mode, the UAA chip is the bus master. In 20K1 mode, the 20K1 chip is the bus master. Under either UAA mode or 20K1 mode, the driver can read and write the configuration space of both UAA chip and 20K1 chip.
