[PATCH v4 19/21] tests/tcg/aarch64: add test-sve-ioctl guest-debug test |
Date: |
Fri, 20 Dec 2019 12:04:36 +0000 |
This test exercises the gdbstub while runing the sve-iotcl test. I
haven't plubmed it into make system as we need a way of verifying if
gdb has the right support for SVE.

v4
- interrogate ZCR_EL1 directly as no longer have vg
