runqemu: kill qemu if it hangs

2023-02-23T12:11:29+00:00

qemu doesn't always behave well and can hang too. kill it with force if it was still alive. Move clean up commands into cleanup() function. (From OE-Core rev: 079c2935d2f585ce49e1c7daab2155fcf0094c48) Signed-off-by: Mikko Rapeli Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

runqemu: add process of option QB_NFSROOTFS_EXTRA_OPT

2023-01-26T22:22:53+00:00

This extra options to be appended to the nfs rootfs options in kernel boot arg. Example config with qemuppc64 in machine config: add r/w size in the nfs rootfs extra option: QB_NFSROOTFS_EXTRA_OPT = "wsize=524288,rsize=524288" re-build and runqemu with nfs again, we can observe the kernel command line added our defined value in QB_NFSROOTFS_EXTRA_OPT: Kernel command line: root=/dev/nfs nfsroot=10.0.2.2:/home/xchen5/testing/build/tmp-glibc/deploy/images/qemuppc64/testnfs,nfsvers=3,port=3049,tcp,mountport=3048,wsize=524288,rsize=524288 rw mem=256M ip=dhcp console=hvc0 console=hvc0 nohugevmalloc (From OE-Core rev: 43a97f5bf3f90c5c1fd603f7dca2b3db2c0e3040) Signed-off-by: Xiangyu Chen Signed-off-by: Luca Ceresoli Signed-off-by: Richard Purdie

runqemu: add QB_SETUP_CMD and QB_CLEANUP_CMD

2022-12-21T10:16:31+00:00

These enable running custom shell setup and cleanup commands before and after qemu. Enables machine configurations to for example run qemu with swtpm to emulate TPM devices. Example config with meta-tpm2 based swtpm in machine config: * image recipe depens on swtpm-native to get the native tools to PATH, same handling as qemu itself do_testimage[depends] += "swtpm-native:do_populate_sysroot" * startup commands for swtpm daemon, note that swtpm socket file has 107 character limit and absolute paths to build environment will not work QB_SETUP_CMD = " \ test -d '${IMAGE_BASENAME}_swtpm' || ( mkdir -p '${IMAGE_BASENAME}_swtpm' && \ swtpm_setup --tpmstate '${IMAGE_BASENAME}_swtpm' --tpm2 --pcr-banks sha256 ); \ swtpm socket --tpmstate dir='${IMAGE_BASENAME}_swtpm' \ --ctrl type=unixio,path='${IMAGE_BASENAME}_swtpm/swtpm-sock' \ --log level=40 --tpm2 -t -d \ " * qemu startup command in machine config is configured enable swtpm device QB_OPT_APPEND += "-chardev socket,id=chrtpm,path='${IMAGE_BASENAME}_swtpm/swtpm-sock' -tpmdev emulator,id=tpm0,chardev=chrtpm -device tpm-tis-device,tpmdev=tpm0" * in this case, swtpm daemon stops automatically with qemu machine, but QB_CLEANUP_CMD could be used to kill a specific process and wipe temporary files Now runqemu and testimage.bbclass can be used with swtpm.

runqemu: do not hardcode the ip address of the nfs server when using tap

Rather, set it similarly to the overall network config. (From OE-Core rev: d5e2ef31b151825613b62e58034e81f72526a944) Signed-off-by: Alexander Kanavin Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

runqemu: limit slirp host port forwarding to localhost 127.0.0.1

2022-11-20T08:29:07+00:00

With default slirp port forwarding config qemu listens on TCP ports 2222 and 2323 on all IP addresses available on the build host. Most use cases with runqemu only need it for localhost and it is not safe to run qemu images with root login without password enabled and listening on all available, possibly Internet reachable network interfaces. Limit qemu port forwarding to localhost 127.0.0.1 IP address. Now qemu machine SSH and telnet ports are only reachable from the build host machine, not full Internet. If qemu machine needs to be reachable from network, then it can be enabled via local.conf or machine config variable QB_SLIRP_OPT: QB_SLIRP_OPT = "-netdev user,id=net0,hostfwd=tcp::2222-:22" (From OE-Core rev: c6b1e3d50bf2feea80b70a42c6fad868fa9e6042) Signed-off-by: Mikko Rapeli Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

runqemu: Do not perturb script environment

2022-10-26T11:28:39+00:00

Instead of changing the script environment to affect the child processes, make a copy of the environment with modifications and pass that to subprocess. Specifically, when dri rendering is enabled, LD_PRELOAD was being passed to all processes created by the script which resulted in other commands (e.g. stty) exiting with a failure like: /bin/sh: symbol lookup error: sysroots-uninative/x86_64-linux/lib/librt.so.1: undefined symbol: __libc_unwind_link_get, version GLIBC_PRIVATE Making a copy of the environment fixes this because the LD_PRELOAD is now only passed to qemu itself.

runqemu: Fix gl-es argument from causing other arguments to be ignored

The code to parse arguments was inadvertently skipping all arguments in the elif block after gl-es if it was specified on the command line. (From OE-Core rev: 718bb8d56f6a24c86e67830a7d13af54df2ebb4e) Signed-off-by: Joshua Watt Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

runqemu: display host uptime when starting

2022-09-12T07:33:56+00:00

In order to be able to debug issues on the host that have an impact on the guest, it is useful to get the uptime of the host while starting so we can match with the events in dmesg. Also include the uptime when cleaning up. (From OE-Core rev: 2d96499823f7de6e16a461426491e015ba63c1ec) Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie
