andrew added a comment to D56551: arm64/vmm: Use the VNCR_EL2 memory page to store guest registers.
We will need to handle accessing different sized registers to support FEAT_D128, e.g. VTTBR_EL2 will be 128 bit there.
andrew added inline comments to D56550: arm64/vmm: Add FEAT_NV2 definitions.
andrew added a comment to D55947: arm64: mte: handle synchronous tag check faults.
I can move them to something like 200/201. I think the Arm Permission Overlay Extension (FEAT_S1POE) could then reuse SEGV_PKUERR as it is similar.

andrew added a comment to D45268: libgcc_s: Add a linker script to link to libgcc.
Was it decided if this was an acceptable approach? I found the sanitizer runtimes also need this to work correctly, so would like to push to fix them
andrew added a comment to D55492: virtio_net: Use bus_dma for rxq/txq buffers.
Does anyone have any more testing they would like to do, or shall I push this to main?

Set TESTSDIR to install the Kyuafile in the correct place
andrew added a comment to D56333: tests/sys: Fix the build on non-arm64.
I'm not sure how that can happen as by including bsd.test.mk a Kyuafile should be created, e.g.
$ cat /usr/obj/.../amd64.amd64/tests/sys/arch/Kyuafile -- Automatically generated by bsd.test.mk.
