From: Chalapathi V
Subject: [PATCH v7 0/3] pnv N1 chiplet model
Date: Wed, 6 Dec 2023 20:43:28 -0600


Thank you for the review and suggestions on V6.

The suggestions and changes requested from V6 are addressed in V7.

Updates in Version 7 of this series are: 
There are no major changes done in revision 7 from revision 6. 
1. The property "parent-obj-name" is removed from nest pervasive chiplet
   model as it is not required.
2. nest pervasive chiplet model is initialized from instance_init handler.

The new qom-tree looks like below.
(qemu) info qom-tree 
/machine (powernv10-machine)
  /chip[0] (power10_v2.0-pnv-chip)
    /n1-chiplet (pnv-N1-chiplet)
      /nest-pervasive-common (pnv-nest-chiplet-pervasive)
        /pervasive-control[0] (memory-region)
      /xscom-n1-chiplet-pb-scom-eq[0] (memory-region)
      /xscom-n1-chiplet-pb-scom-es[0] (memory-region)

Patches overview in V7.
PATCH1: Create a common nest pervasive chiplet model with control chiplet scom
PATCH2: Create a N1 chiplet model and implement powerbus scom registers.
        Connect common nest pervasive model to N1 chiplet model to define
        chiplet control scoms for N1 chiplet.
PATCH3: Connect N1 chiplet model to p10 chip.

Test covered:
Ran make check && make check-avocado and found no obvious issues.

Thank You,

  hw/ppc: Add pnv nest pervasive common chiplet model
  hw/ppc: Add N1 chiplet model
  hw/ppc: N1 chiplet wiring
