Ok, I've now applied all of this series to ppc-for-4.0. > > > GitHub trees available here : > > QEMU sPAPR: > > https://github.com/legoater/qemu/commits/xive-next > > QEMU PowerNV: > > https://github.com/legoater/qemu/commits/powernv-3.1 > > Linux/KVM: > > https://github.com/legoater/linux/commits/xive-4.20 > > OPAL: > > https://github.com/legoater/skiboot/commits/xive > > Best wishes for 2019 ! > > C. > > > > Cédric Le Goater (10): > spapr: modify the prototype of the cpu_intc_create() method > ppc/xive: introduce a XiveTCTX pointer under PowerPCCPU > ppc: replace the 'Object *intc' by a 'ICPState *icp' pointer under the > CPU > spapr/xive: simplify the sPAPR IRQ qirq method for XIVE > ppc: export the XICS and XIVE set_irq handlers > pnv/psi: move the ICSState qemu_irq array under the PSI device model > spapr: move the ICSState qemu_irq array under the machine > ppc/xics: allow ICSState to have an offset 0 > spapr: introduce a new sPAPR IRQ backend supporting XIVE and XICS > spapr: enable XIVE MMIOs at reset > > include/hw/ppc/pnv.h | 2 +- > include/hw/ppc/pnv_psi.h | 1 + > include/hw/ppc/spapr.h | 1 + > include/hw/ppc/spapr_irq.h | 6 +- > include/hw/ppc/spapr_xive.h | 2 +- > include/hw/ppc/xics.h | 6 +- > include/hw/ppc/xive.h | 9 +- > target/ppc/cpu.h | 5 +- > hw/intc/spapr_xive.c | 23 ++- > hw/intc/xics.c | 4 +- > hw/intc/xics_kvm.c | 3 +- > hw/intc/xics_spapr.c | 10 +- > hw/intc/xive.c | 11 +- > hw/ppc/pnv.c | 27 ++-- > hw/ppc/pnv_core.c | 4 +- > hw/ppc/pnv_psi.c | 7 +- > hw/ppc/spapr.c | 12 +- > hw/ppc/spapr_cpu_core.c | 9 +- > hw/ppc/spapr_hcall.c | 11 ++ > hw/ppc/spapr_irq.c | 270 ++++++++++++++++++++++++++++++++++-- > 20 files changed, 342 insertions(+), 81 deletions(-) > -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
