[Qemu-devel] [PATCH v4 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

[Qemu-devel] [PATCH v4 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
