[Qemu-devel] [PATCH 0/3] Mark non-volatile memory regions

Posted by Marc-André Lureau 5 years, 6 months ago

Hi,

As discussed in the "[PATCH v10 6/6] tpm: add ACPI memory clear
interface" thread, and proposed in the "[PATCH] RFC: mark non-volatile
memory region", here is a small series to mark non-volvatile memory
regions and skip them on dump. Upcoming TCG "Platform Reset Attack
Mitigation" will also use this information to eventually skip
non-volatile memory.

Thanks

Marc-André Lureau (3):
  memory: learn about non-volatile memory region
  nvdimm: set non-volatile on the memory region
  memory-mapping: skip non-volatile memory regions in GuestPhysBlockList

Only last patch got reviews, but that means the first are probably ok as well.
Is anybody reviewing & picking the series?

thanks
