This causes the test case to hang: https://lists.gnu.org/archive/html/qemu-ppc/2019-10/msg00826.html More recently, Linux reduced the occurance of operations (e.g., rfi) which stop translation and allow pending interrupts to be processed. This started causing hangs in Linux boot in long-running kernel tests, running with '-d int' shows the decrementer stops firing despite DEC wrapping and MSR[EE]=1. https://lists.ozlabs.org/pipermail/linuxppc-dev/2020-April/208301.html The cause is the broken mtmsr L=1 behaviour, which is contrary to the architecture. From Power ISA v3.0B, p.977, Move To Machine State Register, Programming Note states: If MSR[EE]=0 and an External, Decrementer, or Performance Monitor exception is pending, executing an mtmsrd instruction that sets MSR[EE] to 1 will cause the interrupt to occur before the next instruction is executed, if no higher priority exception exists Fix this by handling L=1 exactly the same way as L=0, modulo the MSR bits altered. The confusion arises from L=0 being "context synchronizing" whereas L=1 is "execution synchronizing", which is a weaker semantic. However this is not a relaxation of the requirement that these exceptions cause interrupts when MSR[EE]=1 (e.g., when mtmsr executes to completion as TCG is doing here), rather it specifies how a pipelined processor can have multiple instructions in flight where one may influence how another behaves.

Bitwise AND with kvm_run->flags to evaluate if we recovered from MCE or not is not correct, As disposition in kvm_run->flags is a two-bit integer value and not a bit map, So check for equality instead of bitwise AND. Without the fix qemu treats any unrecoverable mce error as recoverable and ends up in a mce loop inside the guest, Below are the MCE logs before and after the fix.

This fixes misalignment errors detected by clang sanitizers for ppc64 and ppc64le. In addition, only ppc64 allocates space for VSX registers, so do not save them for ppc32. The kernel only has references to CONFIG_SPE in signal_32.c, so do not attempt to save them for ppc64.
