Given the amount of code and the lack of traction at that time, I haven't respinned until now. However a recent bug found related to the ITS migration convinced me that this work may deserve to be respinned and enhanced. Tests exercise main ITS commands and also test migration. With the migration framework, we are able to trigger the migration from guest and that is very practical actually. What is particular with the ITS programming is that most of the commands are passed through queues and there is real error handling. Invalid commands are just ignored and that is not really tester friendly. The series can be fount at: https://github.com/eauger/kut/tree/its-v4 Best Regards Eric History: v3 -> v4: - addressed comments from Drew and Zenghui - added "page_alloc: Introduce get_order()" - removed "arm: gic: Provide per-IRQ helper functions" - ITS files moved to lib64 - and many more, see individual logs v2 -> v3: - fix 32b compilation - take into account Drew's comments (see individual diff logs) v1 -> v2: - took into account Zenghui's comments - collect R-b's from Thomas References: [1] [kvm-unit-tests RFC 00/15] arm/arm64: add ITS framework https://lists.gnu.org/archive/html/qemu-devel/2016-12/msg00575.html Execution: x For other ITS tests: ./run_tests.sh -g its x non migration tests can be launched invidually.
