[Sound-open-firmware] Using the Qemu DSP emulator
by Daniel Baluta 19 Mar '18

19 Mar '18

Hi, I'm following the instruction on SOF wiki page on how to use the emulator [1] and both VM0 and VM1 are up, anyhow SOF DSP device isn't probed. How do you do it in your qemu setup? Are you using an ACPI file? (or DT?). I'm running the following commands: # ./xtensa-host.sh bxt # ./x86-host.sh bxt and pointing qemu to load my bzimage. thanks, Daniel.

[Sound-open-firmware] [PATCH] Audio format: Bug fix for erroneous fractional multiplication macro
by Seppo Ingalsuo 06 Feb '18

06 Feb '18

Due to misplaced parentheses the computation gives half of correct result and omits rounding. Currently this macro is not used by code in SOF git repository. Developers who may use format.h macros should check their code.

[Sound-open-firmware] [PATCH] rimage: add check for .bss section
by Xiuli Pan 06 Feb '18

06 Feb '18

From: Pan Xiuli <xiuli.pan(a)linux.intel.com> We may have heap buffers for base FW, but they are handled by the runtime function. We did not need to set them as bss in FW manifest. So add check to mark the .bss segment as BSS and other segment as HEAP. Then we only update manifest BSS segmet with BSS section.

[Sound-open-firmware] SOF master build REMINDER
by Pan, Xiuli 06 Feb '18

06 Feb '18

Reminder for applying this patch! On master branch Please check if you have install sudo apt-get install autoconf-archive And see this line when run ./autogen.sh aclocal: installing 'm4/ax_check_compile_flag.m4' from '/usr/share/aclocal/ax_check_compile_flag.m4' or have file 'm4/ax_check_compile_flag.m4' in your git repo. If not you will find these when configure. ./configure: line 3451: syntax error near unexpected token `-msse4.2,' ./configure: line 3451: `AX_CHECK_COMPILE_FLAG(-msse4.2, SSE42_CFLAGS="-DOPS_SSE42 -msse4.2 -ffast-math -ftree-vectorizer-verbose=0",' It seems to be some m4 expand auto check about 'AX_CHECK_COMPILE_FLAG'. If you did no install this macro it will just copy but not expand it in configure file. And then the error will occur. Synced with Keqiao to update CI environment and build guide.

[Sound-open-firmware] [PATCH] dw-dma: add support for interrupt per channel
by Keyon Jie 28 Jan '18

28 Jan '18

On Apollolake, the interrupt number for different channels of the same controller are different, here add implementation of it: register interrupt handler for each channel, and don't need check channel in its specific handler anymore.
