Subject: [PATCH] test: don't use `-cpu max` in GH Actions
|
|
|
|
There appears to be an issue with newer QEMU versions (spotted with Arch
|
|
Linux and C9S containers) which causes the respective GH Action to hang
|
|
when booting a QEMU VM in combination with the `-cpu max` parameter.
|
|
|
|
During (a particularly painful) debugging session I once managed to get
|
|
some output from such "frozen" machine (using `earlycon` and
|
|
`earlyprintk` kernel cmdline options), and in that particular case the
|
|
VM died with a trap caused by an invalid opcode.
|
|
|
|
I couldn't reproduce this locally, only in GH Actions environment with
|
|
Arch Linux and C9S containers. Also, so far I haven't found out which
|
|
specific CPUID flag causes this, but using the `IvyBridge-v2` feature
|
|
set seems to mitigate the issue.
|
|
|
|
(cherry picked from commit 3f56d481e8a3c67c2e795686e6ec3bfc4ea08e1d)
