The following patches fix a number of bugs that were being exposed
when attempting migration with arm64 KVM. Together with some fixes to
QEMU (github.com/stsquad/qemu/tree/migration/fixes-v2) I have
successfully run 500 migrations each on:
* aarch64 kernel, aarch64 user-space
* aarch64 kernel, armhf user-space
* aarch32 kernel, armhf user-space
The various images for testing can be found in:
people.linaro.org/~alex.bennee/images
people.linaro.org/~alex.bennee/testcases/arm64.migration
And the expect script in:
git.linaro.org/people/alex.bennee/test-definitions.git
branch: migration-tests
file: ubuntu/scripts/qemu-file-migrate.expect
The active IRQ patch has two checkpatch failures:
- brace style, consistent with other declarations I was adding to
- use of kzalloc over kcalloc, consistent with other allocs
This patch series has been re-based and re-tested against 4.0-rc1
The branch I've been working with can be found at:
http://git.linaro.org/people/alex.bennee/linux.git
branch: migration/kvmarm-fixes-for-4.0
It includes the two patches from the current kvmarm/master branch.
Cheers,
Alex.
