runqemu: add QB_ROOTFS_EXTRA_OPT parameter

2020-07-02T15:12:36+00:00

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.

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

qemuboot: Improve relative path handling

2017-11-21T13:11:03+00:00

qemuconf files are currently written relative to TOPDIR. What makes more sense is to write paths relative to the location of the file. This makes moving them around and decoding the end paths in runqemu much easier. The effect of this should allow less use of bitbake to determine variables and allow us to simplify runqemu.

classes: drop image dependencies on TOPDIR variable

2017-09-25T13:15:15+00:00

We don't need a dependency on this variable changing, and having one causes locked signature warnings during eSDK installation if you have INITRAMFS_IMAGE_* set (since TOPDIR will always be different between the eSDK and the environment in which it was built). Relates to [YOCTO #12102]. (From OE-Core rev: 073610af04be326f9245ca91714526b390fb72cd) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

qemuboot.bbclass: create deterministic qemuboot.conf file

2017-08-31T16:41:42+00:00

The lines in qemuboot.conf are in random order. This patch fixes this by printing the lines in sorted order. This makes it easier to compare two different builds for any differences.

qemuboot.bbclass: Prevent creating a link loop

2017-08-18T22:46:37+00:00

When IMAGE_NAME and IMAGE_LINK_NAME are equal, do_write_qemuboot_conf will create a symlink that links to itself. Check if this is the case before creating the link. (From OE-Core rev: f46652e77f467861dc68c3a8e54f27d08659222d) Signed-off-by: Mike Looijmans Signed-off-by: Richard Purdie

qemuboot.bbclass: save relative paths in conf file

2017-04-20T06:55:26+00:00

This saves relative paths in the qemuboot.conf file instead of absolute paths. This is to allow the images and kernels to be relocated and still have the testimage and runqemu work.

qemuboot: write native sysroot of qemu-helper into qemuboot.conf

2017-04-13T09:54:10+00:00

Native sysroot of qemu-helper contains all required tools (qemu-system and tunctl atm) for runqemu to work. It's not removed by rm_dir and should always exist. It makes sense to write it into qemuboot.conf to make runqemu to use it as a default directory for native tools. This should also speed up runqemu as it doesn't need to run to run 'bitbake qemu-helper -e' to get its native sysroot.
