[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH 2/2] automation: arm64: Create a test job for testing static allocation on qemu
Add an arm subdirectory under automation/configs for the arm specific configs
and add a config that enables static allocation.
Modify the build script to search for configs also in this subdirectory and to
keep the generated xen binary, suffixed with the config file name, as artifact.
Create a test job that
- boots xen on qemu with a single direct mapped dom0less guest configured with
statically allocated memory
- verifies that the memory ranges reported in the guest's logs are the same
with the provided static memory regions
For guest kernel, use the 5.9.9 kernel from the tests-artifacts containers.
Use busybox-static package, to create the guest ramdisk.
To generate the u-boot script, use ImageBuilder.
Use the qemu from the tests-artifacts containers.
