runqemu: Change nfs to mount via TCP

2020-03-29T19:04:10+00:00

Since kernel commit b24ee6c64ca7 ("NFS: allow deprecation of NFS UDP protocol"), NFS UDP has been disabled by default due to the potential data corruption caused by fragmentation during high loads. So now we cannot boot up with nfs mode and default kernel. We'd better turn to use TCP accordingly.

runqemu: support multiple NICs

2020-03-21T22:39:00+00:00

Emulating more than one network interface with runqemu is a bit tricky, but possible. For example, the following leads to an emulated device with eth0 and eth1: QB_NETWORK_DEVICE_prepend = " \ -device virtio-net-device,mac=52:54:00:12:34:03 \ " or QB_NETWORK_DEVICE_append = " \ -device virtio-net-pci,mac=52:54:00:12:34:03 \ " When booting Qemu with two NICs, the kernel does not know which interface the specified ip=192.168.7.... command line argument should be applied. This delays the boot process for a very long time and a guest wihtout IP configuration. This add two new configuraton parameters to runqemu: QB_CMDLINE_IP_SLIRP and QB_CMDLINE_IP_TAP to explicitely specify the ip= kernel command line arguments for tap and slirp mode. Note: Simply adding "::eth0" broke some builds on the Yocto autobuilder. (From OE-Core rev: 59bfdc331c1494c05ab38804b281878a1f571f6d) Signed-off-by: Adrian Freihofer Signed-off-by: Richard Purdie

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: 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. (From OE-Core rev: 2d5ecc560dcfbaaaff307f8367d789d8c7e00dcf) Signed-off-by: Alexander Kanavin Signed-off-by: Richard Purdie
