H A D | pnv_phb4.h | d3df1f64 Mon Mar 14 09:57:17 CDT 2022 Frederic Barrat <fbarrat@linux.ibm.com> ppc/pnv: Introduce a pnv-phb5 device to match root port
We already have the pnv-phb3 and pnv-phb4 devices for POWER8 and POWER9 respectively. POWER10 uses version 5 of the PHB. It is very close to the PHB4 from POWER9, at least in our model and we could almost keep using the PHB4 model. However the matching root port pnv-phb5-root-port is specific to POWER10 so to avoid confusion as well as making it easy to introduce differences later, we create a pnv-phb5 class, which is mostly an alias for pnv-phb4 for now.
With this patch, the command line for a user-created PHB on powernv10 becomes: -machine powernv10 -nodefaults -device pnv-phb5 -device pnv-phb5-root-port
