Hardware watchpoints on GNU/Linux AArch64

Running

gdb-12.1-10.fc38.aarch64
kernel-6.2.0-0.rc1.20221230gitbff687b3dad6.15.fc38.aarch64

I do not seem to be able to use hardware watchpoints.  GDB just logs
warnings:

warning: Unable to determine the number of hardware watchpoints available.
warning: Unable to determine the number of hardware breakpoints available.

I see AArch64-specific code in GDB, so this is a bit of a surprise to
me.

The machine uses virtualization:

Architecture:           aarch64
  CPU op-mode(s):       32-bit, 64-bit
  Byte Order:           Little Endian

                         asimdhp cpuid asimdrdm lrcpc dcpop asimddp ssbs

Is this actually expected to work?  Would we have more luck on a
bare-metal system?

Thanks,
