[Qemu-devel] [PATCH v4 1/9] ppc/xics: account correct irq status

Fix inconsistent irq status, because of this in the trace logs, for e.g. LSI status was 0x7, i.e. XICS_STATUS_ASSERTED, XICS_STATUS_SENT and XICS_STATUS_REJECTED all set, which did not make sense. So the REJECTED would have been set in earlier interrupt cycle, and then asserted and sent in this

[Qemu-devel] [PATCH v4 0/9] sPAPR xics rework/cleanup

sPAPR xics related changes required for powernv platform. This brings infrastructure to get the xics native mode for powernv. Tested pseries guests in KVM and TCG mode. These are the pending patches of the original set. Changelog v3: * Added ICP_Native and XICSNative in "native" implementation

[Qemu-devel] [PATCH v5 3/3] target-ppc: tlbie/tlbivax should have global effect

tlbie (BookS) and tlbivax (BookE) plus the H_CALLs(pseries) should have a global effect. Introduces TLB_NEED_GLOBAL_FLUSH flag. During lazy tlb flush, after taking care of pending local flushes, check broadcast flush(at context synchronizing event ptesync/tlbsync, etc) is needed. Depending on the

[Qemu-devel] [PATCH v5 2/3] target-ppc: add flag in chech_tlb_flush()

We flush the qemu TLB lazily. check_tlb_flush is called whenever we hit a context synchronizing event or instruction that requires a pending flush to be performed. However, we fail to handle broadcast TLB flush operations. In order to fix that efficiently, we want to differenciate whether

[Qemu-devel] [PATCH v5 0/3] ppc: handle broadcast tlb flush

PowerPC failed to handle broadcast TLB flush operations. Executing instructions that are defined architecturally as synchronizing global TLB should have a global effect. * tlbie on BookS * tlbivax on BookE * H_CALLs (H_REMOVE, H_BULK_REMOVE and H_PROTECT) in case of pseries, since they
