Commit26646f3"x86/mce: translate passed-in GPA to host machine address" and commit4ddf474"tools/xen-mceinj: Pass in GPA when injecting through MSR_MCI_ADDR" forgot to consider reserved domain ID and mistakenly add MC_MSRINJ_F_GPADDR flag for them, which in turn causes bug reported by http://lists.xenproject.org/archives/html/xen-devel/2016-05/msg02640.html. This patch removes MC_MSRINK_F_GPADDR flag and checks this when injecting to reserved domain IDs except DOMID_SELF, and treats the passed-in address as host machine address.

Xen MCE test suite --------------- The Xen MCE test suite is a collection of tools and test scripts for testing the Xen MCE processing features. The goal is to cover most Xen MCE processing code paths and features with automation tests. In the Package -------------- Here is a short description of what is included in the package README This is document Makefile For compile cases/* Contains all test cases, which may be organized in sub-directories, the interface of test case is a shell script under cases/, such as: -- cases/srao_mem/dom0/cases.sh config/* Contains test configuration files, which specifies the parameters for test cases, etc. lib/* Contains some shell scripts, in which some common shell functions and variable definitions are defined to be used by test cases. tools/* Tools used by MCE test suites, now only xen-mceinj tool. results/ When test is done, the test result will be placed in this directory, test results of various cases may be in corresponding directory. For example, files in results/srao_mem_dom0/result is the result for test case cases/srao_mem/dom0/cases.sh, there will be 3 result conditions: PASSED/FAILED/NORESULT. results/<test_case>/testlog #the test log during testing results/<test_case>/mcelog #mcelog output during testing results/<test_case>/xenlog #Xen log during testing results/<test_case>/gklog #VM guest kernel log during testing results/<test_case>/guest_config #config file used to create guest Test Instruction ---------------- 1. make sure you have a dom0 with mce support CONFIG_X86_MCE=y CONFIG_X86_MCE_INTEL=y CONFIG_X86_MCE_AMD=y CONFIG_X86_MCE_THRESHOLD=y CONFIG_X86_MCE_INJECT=y 2. run system at xen and start xend. A installed guest image is necessary when do guest MCE error injection. 3. compile tools that used to test. in mce-test, $make. Note: make sure compile xen/tools before do this step 4. run test cases that you want. e.g. $sh cases/srao_mem/dom0/cases.sh -d 0 -p 0x0200 -c 2 -t 1 5. get test result in results directory Notes ---------------- All test cases fake a error and inject this error in 0x180020, For Xen test cases(e.g. cases/srao_mem/xen/cases.sh), error happen on every page may cause a Xen panic.
