Some tests failed in qemu 7.0.0

[KuangjuX]

Hello! I am using riscv-hyp-tests to test QEMU 7.0.0, the command I executed is as follows:

qemu-system-riscv64 --machine virt -m 3G -bios none -kernel build/qemu/rvh_test.bin -nographic

It turns out that there are a few tests that are failing:

risc-v hypervisor extensions tests
check_misa_h                                                          PASSED
tinst_tests                                                           FAILED

second_stage_only_translation                                         FAILED
two_stage_translation                                                 PASSED
end

I'm wondering if QEMU 7.0.0 is still not the full implementation of the riscv H extension, and I'd like to know which version currently passes the test. Thanks!

Hey, @KuangjuX, would you be able to check if the tests are still failing in the newer version of QEMU (8.0.1)? I believe that some of the tests don't consider the fact that the specification allows for multiple implementations. Therefore, we might need to make some adjustments or provide leeway in certain tests.

The tests fail in QEMU (8.1.2) as well.

risc-v hypervisor extensions tests
check_misa_h PASSED
tinst_tests FAILED
wfi_exception_tests PASSED
hfence_test FAILED
virtual_instruction FAILED
interrupt_tests PASSED
check_xip_regs FAILED
m_and_hs_using_vs_access ERROR: instruction fault without return address (mhandler, 237)

Could you please help with this.

Thank you.
