There is still one thing I'm a bit puzzled by though: HCR_EL2.TID0 mandates trapping of the AArch32 JIDR register, but I couldn't find a trace of it in the QEMU code, and trying to read it seems to generate an exception. It isn't like anyone is going to miss it, but I wonder if it should be implemented... It could also be that I'm missing the obvious and that my testing is broken! ;-) Marc Zyngier (3): target/arm: Honor HCR_EL2.TID2 trapping requirements target/arm: Honor HCR_EL2.TID1 trapping requirements target/arm: Handle trapping to EL2 of AArch32 VMRS instructions target/arm/helper-a64.h | 2 ++ target/arm/helper.c | 64 ++++++++++++++++++++++++++++++---- target/arm/internals.h | 8 +++++ target/arm/translate-vfp.inc.c | 12 +++++-- target/arm/vfp_helper.c | 27 ++++++++++++++ 5 files changed, 103 insertions(+), 10 deletions(-) -- 2.20.1 _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
