[Qemu-devel] [PATCH v1 3/3] hw/ppc/pnv_homer: add PowerNV homer device model |
|
Date: |
Tue, 10 Sep 2019 12:40:19 +0530 |
add PnvHOMER device model to emulate homer memory access
for pstate table, occ-sensors, slw, occ static and dynamic
values for Power8 and Power9 chips. Fix few coding style
warnings given by checkpatch.pl.
