[alsa-devel] [PATCH] alsa-driver git repo: Build problems when copying symlink to itself

Hi, After doing a "simple": git clone alsa-driver git clone alsa-kernel cd alsa-driver ./gitcompile --with-debug=full --with-isapnp=yes --with-sequencer=yes --with-moddir=updates/alsa: The build bombed out pretty quickly with the following error.

[alsa-devel] [PATCH] omap3: alsa-soc: Remove restrictive check for cpu type
by Sanjeev Premi 14 Mar '11

14 Mar '11

Current check for cpu type is too restrictive leading to failures for other silicons in same family. The problem was found while testing audio playback on AM37x and AM35x processors. But should exist on OMAP36xx as well.

[alsa-devel] Fwd: Possible bug in sound/pci/atiixp.c ?
by Amir Shamsuddin 14 Mar '11

14 Mar '11

Hi, My laptop occasionally fails to resume from suspend, and when it does, I see (only) this error message on screen: [nnn.nnn] atiixp: codec reset timeout I had a look at the code where this comes from, and while I'm not sure it's related to my resume problem, it does (to my untrained eyes) look like there is a small bug in the function snd_atiixp_aclink_reset in file sound/pci/atiixp.c: (lines 500 - 536 in latest git) static int snd_atiixp_aclink_reset(struct atiixp *chip) { int timeout; [snip] timeout = 10; while (! (atiixp_read(chip, CMD) & ATI_REG_CMD_ACLINK_ACTIVE)) { /* do a hard reset */ [snip] if (--timeout) { snd_printk(KERN_ERR "atiixp: codec reset timeout\n"); break; } } [snip] } Surely the timeout condition should be negated, so the timeout message and loop break is only hit when 'timeout' reaches zero? ie. if (! --timeout) { Or am I missing something?

Please repost, there were quite a few issues raised with this revision even outside the firmware. For the purpose of getting things into mainline I'd recommend splitting out the functionaltiy which allows firmware to be loaded dynamically at runtime as a second patch.

[alsa-devel] [PATCH] alsamixer: fix build on uClibc
by Peter Korsgaard 14 Mar '11

exp10 is a glibc extension, which isn't supported on uClibc. Luckily, exp10() is trivial to compute based on exp(), so add a wrapper for the uClibc case.

[alsa-devel] Help hunting down a regression
by Colin Guthrie 12 Mar '11

12 Mar '11

So you may know from my other thread that I'm trying to find a regression introduced in the alsa drivers sometime ago. I suspect that 2.6.35 kernels were OK but I'm trying to compile the drivers from that era with little success. I'm cloning alsa-driver and alsa-kernel, and while I can checkout v2.6.35 in alsa-kernel OK, it's nigh on impossible to checkout the corresponding alsa-driver. I can't help but feel I'm missing a trick here, so figured I'd ask first before banging my head against a wall for several hours.
