x86/intel-iommu: properly ack edu interrupt Writing zero to EDU_REG_INTR_RAISE doesn't clear the status, because the value is ORed in. The edu spec says that to clear the interrupt, regardless of using MSI or not, one should write the value of the interrupt status register to the interrupt acknowledge register from the interrupt handler.

See http://www.linux-kvm.org/page/KVM-unit-tests for a high-level description of this project, as well as running tests and adding tests HOWTOs.
This directory contains sources for a kvm test suite.
To create the test images do:
./configure make
in this directory. Test images are created in .//*.flat
The tests can be built as standalone To create and use standalone tests do:
./configure make standalone (send tests/some-test somewhere) (go to somewhere) ./some-test
‘make install’ will install all tests in PREFIX/share/kvm-unit-tests/tests, each as a standalone test.
Then use the runner script to detect the correct invocation and invoke the test:
./x86-run ./x86/msr.flat
or:
./run_tests.sh
to run them all.
To select a specific qemu binary, specify the QEMU= environment variable:
QEMU=/tmp/qemu/x86_64-softmmu/qemu-system-x86_64 ./x86-run ./x86/msr.flat
.: configure script, top-level Makefile, and run_tests.sh ./scripts: helper scripts for building and running tests ./lib: general architecture neutral services for the tests ./lib/<ARCH>: architecture dependent services for the tests ./<ARCH>: the sources of the tests and the created objects/images
See /README for architecture specific documentation.
Currently there is a mix of indentation styles so any changes to existing files should be consistent with the existing style. For new files:
Patches are welcome at the KVM mailing list kvm@vger.kernel.org.
Please prefix messages with: [kvm-unit-tests PATCH]
You can add the following to .git/config to do this automatically for you:
[format]
subjectprefix = kvm-unit-tests PATCH
Additionally it‘s helpful to have a common order of file types in patches. Our chosen order attempts to place the more declarative files before the code files. We also start with common code and finish with unit test code. git-diff’s orderFile feature allows us to specify the order in a file. The orderFile we use is scripts/git.difforder. Adding the config with git config diff.orderFile scripts/git.difforder enables it.
