[-qemu,0/3] hw/cxl: Support dirty shutdown

Message

Hello,

The following adds support for emulating dirty shutdown semantics.

Patch 1 is a trivial cleanup, patch 2 adds get/set shutdown state
commands, and patch 3 introduces a new 'dirty-shutdown=N' parameter
for type3 memdevs which explicitly sets the dirty shutdown counter
to whatever passed value.

This series aids testing Global Persistent Flush support in the kernel.

Applies against the 'cxl-2024-11-27' branch in Jonathan's tree.

Thanks!
