There are lots of logs at https://kerneltests.org/builders, in the 'next'
column of qemu tests. One example is
https://kerneltests.org/builders/qemu-arm-v7-next/builds/511/steps/qemubuildcommand/logs/stdio
Sample command line:
qemu-system-arm -M mcimx7d-sabre \
-kernel arch/arm/boot/zImage -no-reboot -snapshot \
-usb -device usb-storage,drive=d0,bus=usb-bus.1 \
-drive file=rootfs-armv7a.ext2,if=none,id=d0,format=raw \
-m 256 -nic user -display none \
--append "root=/dev/sda rootwait earlycon=ec_imx6q,mmio,0x30860000,115200n8 console=ttymxc0,115200" \
-dtb arch/arm/boot/dts/imx7d-sdb.dtb \
-nographic -monitor null -serial stdio
This is with a modified imx_v6_v7_defconfig and root file system from
https://github.com/groeck/linux-build-test/blob/master/rootfs/arm-v7/rootfs-armv7a.ext2.gz
The -EINVAL return value is from
if (p < s + 2 || !isdigit(p[-2]) || p[-1] != 'p')
in devt_from_devname().
