| Series | Power11 support for QEMU [PSeries] | expand |
Hey Aditya, Thanks for this, I think since we're past the hard freeze it may have to wait until next release. If it was simply a new PRV maybe it could be squeezed in, but since it has this PCR tangle then it's a bit non-trivial. Apologies I didn't get to reviewing it earlier, will get it in 9.2.

Overview ============ Split "Power11 support for QEMU" into 2 patch series: pseries & powernv. This patch series is for pseries support for Power11. As Power11 core is same as Power10, hence much of the code has been reused from Power10. Power11 was added in Linux in: commit c2ed087ed35c ("powerpc: Add Power11 architected and raw mode") Git Tree for Testing ==================== QEMU: https://github.com/adi-g15-ibm/qemu/tree/p11-v6-pseries Has been tested with following cases: * '-M pseries' / '-M pseries -cpu Power11' * '-smp' option tested * with compat mode: 'max-cpu-compat=power10' and 'max-cpu-compat=power9' * with/without device 'virtio-scsi-pci' * with/without -kernel and -drive with qcow_file Linux with Power11 support: https://github.com/torvalds/linux, since v6.9-rc1 Changelog ========= v6: + reorganised patches such that Power11 introduction is at end, and cleanups and fixes is done before + patch #1: renamed macros from POWER_* to PCC_* + patch #2: rename 'logical_pvr' to 'spapr_logical_pvr' to better convey the context v5: + split patch series into pseries+powernv + patch #1: apply harsh's patch to reduce duplication + patch #2: simplified, by removing duplication + patch #3: update docs, according to harsh's suggestion + patch #4: no functional change, #define used for P9 & P10 pcr_supported + patch #5: no change 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 Aditya Gupta (4): target/ppc: Introduce 'PowerPCCPUClass::spapr_logical_pvr' target/ppc: Fix regression due to Power10 and Power11 having same PCR target/ppc: Add Power11 DD2.0 processor ppc/pseries: Add Power11 cpu type Harsh Prateek Bora (1): target/ppc: Reduce code duplication across Power9/10 init code docs/system/ppc/pseries.rst | 17 +++- hw/ppc/spapr_cpu_core.c | 1 + target/ppc/compat.c | 11 +++ target/ppc/cpu-models.c | 3 + target/ppc/cpu-models.h | 3 + target/ppc/cpu.h | 3 + target/ppc/cpu_init.c | 188 +++++++++++++++--------------------- target/ppc/cpu_init.h | 92 ++++++++++++++++++ 8 files changed, 205 insertions(+), 113 deletions(-) create mode 100644 target/ppc/cpu_init.h
