Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.9-20170303' into staging
ppc patch queuye for 2017-03-03 This will probably be my last pull request before the hard freeze. It has some new work, but that has all been posted in draft before the soft freeze, so I think it's reasonable to include in qemu-2.9. This batch has: * A substantial amount of POWER9 work * Implements the legacy (hash) MMU for POWER9 * Some more preliminaries for implementing the POWER9 radix MMU * POWER9 has_work * Basic POWER9 compatibility mode handling * Removal of some premature tests * Some cleanups and fixes to the existing MMU code to make the POWER9 work simpler * A bugfix for TCG multiply adds on power * Allow pseries guests to access PCIe extended config space This also includes a code-motion not strictly in ppc code - moving getrampagesize() from ppc code to exec.c. This will make some future VFIO improvements easier, Paolo said it was ok to merge via my tree. # gpg: Signature made Fri 03 Mar 2017 03:20:36 GMT # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.9-20170303: target/ppc: rewrite f[n]m[add,sub] using float64_muladd spapr: Small cleanup of PPC MMU enums spapr_pci: Advertise access to PCIe extended config space target/ppc: Rework hash mmu page fault code and add defines for clarity target/ppc: Move no-execute and guarded page checking into new function target/ppc: Add execute permission checking to access authority check target/ppc: Add Instruction Authority Mask Register Check hw/ppc/spapr: Add POWER9 to pseries cpu models target/ppc/POWER9: Add cpu_has_work function for POWER9 target/ppc/POWER9: Add POWER9 pa-features definition target/ppc/POWER9: Add POWER9 mmu fault handler target/ppc: Don't gen an SDR1 on POWER9 and rework register creation target/ppc: Add patb_entry to sPAPRMachineState target/ppc/POWER9: Add POWERPC_MMU_V3 bit powernv: Don't test POWER9 CPU yet exec, kvm, target-ppc: Move getrampagesize() to common code target/ppc: Add POWER9/ISAv3.00 to compat_table Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
