* runqemu: add QB_SETUP_CMD and QB_CLEANUP_CMDMikko Rapeli2022-12-211-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: limit slirp host port forwarding to localhost 127.0.0.1Mikko Rapeli2022-11-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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 <mikko.rapeli@linaro.org> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* runqemu: Do not perturb script environmentJoshua Watt2022-10-261-12/+14
| | | | | | | | | | | | | | | | | | | | | 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: Allow auto detection of the correct graphics optionsRichard Purdie2022-04-141-7/+26
| | | | | | | | | | | | | | | | | Running "runqemu qemux86 kvm" when qemu is configured for sdl and/or gtk display output currently leads to a poor user experience with no cursor and corrupted fonts in the gtk case. This is due to no options being passed to qemu which leads to the loss of the font envirornment variable and the show-cursor option. If the user hasn't specified a display type, grep the output of "qemu-system-xxx --help" for the display types and pick the "best" which ensures our config is passed in. That resolves the gtk font issue and the cursor issue with both sdl and gtk.

| | | | | | | | | | | | | | Some of the host distributions build the drivers in a way (RPATH/RUNPATH) that tricks uninative loader into loading pieces of the host libc, if the same pieces haven't been previously loaded by native binaries.

* qemu: add a hint on how to enable CPU render nodes when a suitable GPU is absentAlexander Kanavin2021-08-231-0/+2
| | | | | | | | | | | | | | | | | | | This is particularly useful for llvm-accelerated GL rendering from qemu guest to an offscreen buffer (accessible over vnc or spice) using llvmpipe on the host, rather than using unaccelerated swrast renderer in the guest. This is the best that can be done in the absence of a host GPU with render node support (such as old Matrox cards common in servers, or fully virtualized cloud environments with no GPU at all). Note: even though NVidia blob drivers do support render nodes, they do not support gbm (yet?), and so rendering will fall back to llvmpipe as well even when the system has a 3000 euro NVidia GPU. Cue Linus picture.

| | | | | | | | | | | | | | | | | | We have a working theory that IO queues on the autobuilder are impacting runtime testing under qemu, particularly async writes which inice does not influence. We already pass the snapshot option to qemu which copies the image and runs out of the copy. Add in the ability to copy the image to a specificed location which can be a tmpfs. This means that writes to the image would no longer be blocked by other writes to disk in the system. Preliminary tests show that this does improve the qemu errors at the expense of sometimes showing qemu startup timeouts as on a loaded system with a large test image, it can take longer than 120s to copy the image to tmpfs. Having a most consistent failure mode for loaded tests is probably desireable though.

| | | | | | | | | | | We have an issue where qemu is being starved of resources on our autobuilders. We can't raise its priority without special capacilties, therefore add a hook which if present can allow this to happen using an executable "~/runqemu-renice".

| | | | | | | | | | | The autobuilder managed to pass the nographic option with "sdl gl" due to a problem elsewhere. It would have been useful for runqemu to have errored rather than passing conflicting options to qemu. Add an error for this invalid usecase.

* runqemu: If using a vmtype image do not add the -no-reboot flagJason Wessel2020-06-281-1/+3
| | | | | | | | | | | | | | | | | | | | There is no way to use runqemu and turn off the no-reboot flag with a command line argument. If someone really wants it back it can be added with the qemuparams="" argument. Also if you use the "halt -p" from user space, the qemu will exit when it is complete. It is impossible to test self deploying image with runqemu if you cannot reboot the device. One might argue that you can run runqemu in a loop, but that defeats the purpose of having a wrapper around a tool that already does what is needed in the first place. For the vmtype images, the -no-reboot flag should not be added.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Major update after v4.2. Changes: - os_find_datadir() was changed after the v4.2 release causing v5.0 to not find the bios and not boot the image. Fix is sent to upstream qemu. See: qemu/find_datadir.patch - v5.0 binary had host contamination for dynamically linked libraries, "--extra-ldflags='${LDFLAGS}'" in EXTRA_OECONF resolved the issue - bluetooth code was removed: qemu.git$ git show 1d4ffe8dc7 hence removed PACKAGECONFIG[bluez] - -show-cursor qemu option is now deprecated, updated scripts/runqemu to use updated option instead - added PACKAGECONFIG definitions - added qemu-ptest to conf/distro/include/ptest-packagelists.inc - increased support for ARM architecture, cpu and board - removed patches merged upstream and refreshed existing ones Testing: Build core-image-minimal against the machines in openembedded-core/meta/conf/machine and succesfully booted with qemu v5.0 Ran qemu-ptest on x86-64 and arm64 with identical results: PASS: 1166 SKIP: 0 FAIL: 0 (From OE-Core rev: ee9ec9e344541c1ccd9b9b8e3b8c1e00d008ad85) Signed-off-by: Sakib Sajal <sakib.sajal@windriver.com> Signed-off-by: Joe Slater <joe.slater@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* runqemu: force software x11 renderer for SDL when GL is not in useAlexander Kanavin2020-05-121-0/+3
| | | | | | | | | | | | | If libsdl is configured with opengl enabled, it will try to use GL renderers to open a window even if qemu doesn't use virgl. Setting the environment variable forces a software X11 renderer, which is the same one used when libsdl has opengl switched off. This avoids needlessly loading the GL libraries and drivers from the host.

| | | | | | | | | | | | | | | | Falling through to host GL stack via epoxy chrpath hack was found to be problematic in case of SDL particularly (because it does not actually use epoxy, and does its own dlopen()). So let's just use the mesa-native libraries everywhere, but instruct them to load DRI drivers from the host. NVidia's proprietary blob users have to take care of themselves, I'm afraid.

| | | | | | | | | | | | | | | | | | | | | Content of the optional parameter will be appended to the rootfs-device in the qemu configuration, in case QB_ROOTFS_OPT is not specified. By default this is empty. Example use cases are: Defining 'readonly' when using squashfs, so multiple instances of qemu can share the same base image, something that cannot be done by just specifying 'snapshot'. Defining 'bootindex=0' which helps to get past the EFI shell in ovmf-binary. This also enables the use case of running WIC images with EFI bootloader through the testimage.bbclass.

| | | | | | | | | | | | | | 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.

* runqemu: support multiple NICsAdrian Freihofer2020-03-211-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* runqemu: Add network bridge supportJoshua Watt2020-01-101-2/+11
| | | | | | | | | | | | | | | | | | | | 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=<INTERFACE>" 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.
