runqemu: check the qemu PID has been set before kill()ing it

2021-12-15T07:40:29+00:00

If runqemu is killed, check that we have a valid PID for the qemu before sending a kill() to it.

runqemu: Remove potential lock races around tap device handling

2021-07-20T18:05:45+00:00

The qemu tap device handling is potentially race ridden. We pass the fd to the main qemu subprocess which is good as it means the lock is held as long as the qemu process exists. This means we shouldn't unlock it ourselves though, only close the file. We also can't delete the file as we have no idea if qemu is still using it. We could try and obtain an exclusive new lock, then the file would be safe to unlink but it doesn't seem worth it. Also fix the same issue in the port lock code.

runqemu: Ensure we cleanup snapshot files after image run

2021-04-30T13:37:26+00:00

We need to cleanup snapshot files if we make a copy of them to ensure the tmpfs doesn't run out of space. There is already NFS code needing this so make it a generic code path.

oeqa/runqemu: Support RUNQEMU_TMPFS_DIR as a location to copy snapshot images to

2021-04-06T08:30:10+00:00

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. (From OE-Core rev: fd1c26ab426c3699ffd8082b83d65a84c8eb8bff) Signed-off-by: Richard Purdie

runqemu: do not stop processing graphical options after nographic

Some options such as egl-headless are fully compatible with it, so there is no need to quit. (From OE-Core rev: 66d11106f9e76d19e397ba3d14c3a22726033567) Signed-off-by: Alexander Kanavin Signed-off-by: Richard Purdie

runqemu: modify novga to conform to documentation

2021-03-11T14:00:36+00:00

Passing 'novga' only adds '-vga none' to the qemu commandline and does not prevent other vga devices from being added, contrary to the documentation/help. Clean-up the vga logic and add the ability to prevent other vga devices from being added.

runqemu: correct forcing of ttyS0

2021-03-11T14:00:36+00:00

Some platforms do not use ttyS* for their serial consoles (e.g., qemuarm and qemuarm64). The hardcoding of this can cause issues. Modify runqemu to use the serial consoles defined in SERIAL_CONSOLES instead of hardcoding.

runqemu: add QB_GRAPHICS

2021-03-11T14:00:36+00:00

Add a new runqemu field for VGA devices. Currently, these are being set in QB_OPT_APPEND, which can make them difficult to override if importing the config file into another one.

runqemu: use "raw" instead of "bin" for ovmf

2021-03-06T22:39:03+00:00

bin is not an acceptable format for qemu and will throw an error is set. The correct format in this case is raw. (From OE-Core rev: cd279aeb986b4676ea8ecb1e7b12c7e29e83460a) Signed-off-by: Jon Mason Change-Id: I9d78e356d39ecb15bef886c19870b029d9badd65 Signed-off-by: Richard Purdie
