runqemu: Add network bridge support

2020-01-10T21:18:23+00:00

Qemu supports attaching the virtual machine to an existing network bridge interface via the qemu-bridge-helper program (as long as the system is correctly configured to give the user permissions). Add support for runqemu to do this also via the "bridge=" argument. Note that for this to work correctly, the host qemu-bridge-helper must be used, not the one that might have been built by qemu-native. In order for qemu to correctly find this program, a qemu-oe-bridge-helper program has been added to qemu-helper-native, and runqemu will use this helper as the bridge helper. The helper will look for the host qemu-bridge-helper first by looking in the QEMU_BRIDGE_HELPER environment variable, then by search common paths where the helper is installed.

runqemu: add virtio block device

2020-01-06T23:54:39+00:00

Implement new QB_DRIVE_TYPE="/dev/vdb" which falls back to virtio block device emulated by qemu. That is needed to support following qemu command line: -drive id=disk0,file=%s,if=none,format=%s \ -device virtio-blk-device,drive=disk0' Real use case is arm64 emulation with qemu with atf+optee+uboot, so that uboot driver sees this disk and able to load from it.

runqemu: Add multiconfig support

2020-01-01T10:46:16+00:00

Users may want to run qemu against a specific multiconfig instead of the base configuration, so give them the ability to specify which config should be used with the MULTICONFIG environment variable.

runqemu: handle tap device creation failure properly

2019-12-15T09:10:46+00:00

If we fail to run the command to generate the tap devices then we should show a reasonable message and then exit, without showing a traceback. "return 1" at this point in the code does nothing because the caller doesn't check the return, so just use sys.exit().

runqemu: log parameters correctly within testimage

2019-12-15T09:10:46+00:00

It is not a good idea to mix logging and calls to print() - if the output is being captured the result can be that the two types of output are not recorded contiguously; this could be observed if an error occurred running runqemu from inside testimage: ---------- snip ---------- ERROR: core-image-minimal-1.0-r0 do_testimage: Output from runqemu: runqemu - INFO - Continuing with the following parameters: runqemu - INFO - Setting up tap interface under sudo sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper runqemu - ERROR - Setting up tap device failed: Command '('sudo', '/home/paul/poky/poky/scripts/runqemu-ifup', '1000', '1000', '/home/paul/poky/poky/build/tmp/work/x86_64-linux/qemu-helper-native/1.0-r1/recipe-sysroot-native/usr/bin')' returned non-zero exit status 1.

runqemu: Remove disabling of high resolution timer

2019-10-15T13:16:11+00:00

The option 'highres=off' sneaked itself into the runqemu script for all configurations, where the root filesystem type is not 'cpio' or 'cpio.gz'.

runqemu: unset another environment variable for 'egl-headless'

2019-10-15T13:16:10+00:00

Some host distributions (opensuse for example) are using 'pkgconf', which, unlike the original pkg-config, appends PKG_CONFIG_SYSROOT_DIR to every directory from the .pc file.

runqemu: decouple gtk and gl options

This will allow not having to multiply these options for the sdl frontend, instead combining them as needed. (From OE-Core rev: 922eb5012364b1603338cfa617712b941e892bbf) Signed-off-by: Alexander Kanavin Signed-off-by: Ross Burton Signed-off-by: Richard Purdie
