[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] Qemu code loader updates pushed.
by Liam Girdwood 26 Feb '18

26 Feb '18

I've just pushed some updates so the the qemu xtensa VM can now self code load FW binaries (without x86 VM Linux driver). This is useful for debugging any boot related problems or as a functional test harness for xtensa binaries. Supported platforms are BYT, CHT, BSW, HSW, BDW, APL and CNL. Liam
