Overview
============
Add support for Power11 powernv machine type.
As Power11 core is same as Power10, hence much of the code has been reused
from Power10.
Power11 PSeries already added in QEMU in:
commit 273db89bcaf4 ("ppc/pseries: Add Power11 cpu type")
Git Tree for Testing
====================
QEMU: https://github.com/adi-g15-ibm/qemu/tree/p11-powernv-v10
The patches apply cleanly on below commit:
95b9e0d2ade5 ("Merge tag 'for-upstream' of https://gitlab.com/bonzini/qemu
into staging")
Tests ran:
* `make check`
* '-M powernv' / '-M powernv10' / '-M powernv11'
* '-smp' option tested
* 'e1000e' device
* tested changing irq affinities to remote chips for xive functionality
* compile test with --without-default-devices
skiboot with Power11 support: https://github.com/open-power/skiboot, since
commit 785a5e3
Linux with Power11 support: https://github.com/torvalds/linux, since v6.9-rc1
Changelog
=========
v10:
+ [PATCH 1/8]: Do same change for Power11 as done for Power10 in commit
46d03b,
as changes required for successful build with --without-default-devices
+ [PATCH 3/8]: Added new patch to remove assuming chip as Power10 in xive2
+ rebase to upstream
v9
(https://lore.kernel.org/qemu-devel/[email protected]/):
+ [PATCH 1/7]: apply hunks from commit cf0eb929e59cb, and commit
24c8fa968a6d8, for changes that were done for Power10, as those changes
make sense for Power11 also
+ [PATCH 3/7]: fixed build breakage identified with QEMU CI, due to changes
in upstream function pointer types
v8
(https://lore.kernel.org/qemu-devel/[email protected]/):
+ rebase to upstream
+ propose myself as a powernv reviewer
v7
(https://lore.kernel.org/qemu-devel/[email protected]/):
+ use Power10 models of homer, sbe, occ, psi, lpc. As they are same.
+ switch powernv tests to use buildroot images instead of op-build images
+ add functional test for powernv11
- remove dynamic sysbus device for PHBs, so no more dynamic number of
PHBs in Power11 as it became complex to handle it and not much used
v6
(https://lore.kernel.org/qemu-devel/[email protected]/):
+ make Pnv11Chip's parent as PnvChip, instead of Pnv10Chip
+ rebase on upstream/master
v5
(https://lore.kernel.org/qemu-devel/[email protected]/):
+ add chiptod
+ add instance_init for P11 to use P11 models
+ move patch introducing Pnv11Chip to the last
+ update skiboot.lid to skiboot's upstream/master
v4:
+ patch #5: fix memory leak in pnv_chip_power10_quad_realize
- no change in other patches
v3:
+ patch #1: version power11 as power11_v2.0
+ patch #2: split target hw/pseries code into patch #2
+ patch #3,#4: fix regression due to Power10 and Power11 having same PCR
+ patch #5: create pnv_chip_power11_dt_populate and split
pnv_chip_power10_common_realize as per review
+ patch #6-#11: no change
- remove commit to make Power11 as default
v2:
+ split powernv patch into homer,lpc,occ,psi,sbe
+ reduce code duplication by reusing power10 code
+ make power11 as default
+ rebase on qemu upstream/master
+ add more information in commit descriptions
+ update docs
+ update skiboot.lid
