To: buildroot
Hi all,
I am using Buildroot to build a fs for an embedded system (at91sam9263).
The kernel version is 2.6.25 with the at91 and at91-exp patches.
I am trying to get sound working on my board using the AC97 interface
on the at91sam9263 but I am having issues with alsa-lib/alsa-utils.
(using the dummy sound driver snd_dummy)
# alsamixer
ALSA sound/core/control.c:1224: unknown ioctl = 0xc2c85512
alsamixer: function snd_mixer_load failed: Inappropriate ioctl for device.
strace leads me deeper towards the problem (see bottom of message)
Does anyone know if there is some obscure buildroot config option that
could be causing this?
Any other ideas?
Thanks,
Matt

Hi,
Thanks for pointing this out for me, the interesting thing now is that
i had to *disable* the -mabi=aapcs-linux option and everything started
working.
Maybe there is a way we can detect that the kernel has been built with
this option, blindly assuming that it's needed for arm doesn't seem to
be working.

This is from arch/arm/Makefile of linux-2.6.25.10:
ifeq ($(CONFIG_AEABI),y)
CFLAGS_ABI :=-mabi=aapcs-linux -mno-thumb-interwork
else
CFLAGS_ABI :=$(call cc-option,-mapcs-32,-mabi=apcs-gnu) $(call
cc-option,-mno-thumb-interwork,)
endif
so -mabi=aapcs-linux should only be enabled if the toolchain is using EABI.
alsa-lib.mk:
ifeq ($(BR2_arm),y)
ALSA_LIB_ABI:=-mabi=aapcs-linux
else
ALSA_LIB_ABI:=
endif
should probably be replaced with:
ifeq ($(BR2_ARM_EABI),y)
ALSA_LIB_ABI:=-mabi=aapcs-linux
else
ALSA_LIB_ABI:=
endif
