[PATCH RFC] icount: don't adjust virtual time backwards after warp

With icount shift=auto, the QEMU_CLOCK_VIRTUAL can be adjusted backwards after a warp, resulting in the machine observing time going backwards. Linux on powerpc can't handle this, and it results in lockup due to a time delta underflowing. This patch seems to solve it, no more backwards time observ

[PULL 16/30] target/ppc: Add SRR1 prefix indication to interrupt handlers

From: Nicholas Piggin ISA v3.1 introduced prefix instructions. Among the changes, various synchronous interrupts report whether they were caused by a prefix instruction in (H)SRR1. The case of instruction fetch that causes an HDSI due to access of a process-scoped table faulting on the partition

[PULL 12/30] ppc/spapr: load and store l2 state with helper functions

From: Nicholas Piggin Arguably this is just shuffling around register accesses, but one nice thing it does is allow the exit to save away the L2 state then switch the environment to the L1 before copying L2 data back to the L1, which logically flows more naturally and simplifies the error paths.

[PULL 20/30] target/ppc: Fix sc instruction handling of LEV field

From: Nicholas Piggin The top bits of the LEV field of the sc instruction are to be treated as as a reserved field rather than a reserved value, meaning LEV is effectively the bottom bit. LEV=0xF should be treated as LEV=1 and be a hypercall, for example. This changes the instruction execution t

[PULL 25/30] spapr: TCG allow up to 8-thread SMT on POWER8 and newer CPUs

From: Nicholas Piggin PPC TCG supports SMT CPU configurations for non-hypervisor state, so permit POWER8-10 pseries machines to enable SMT. This requires PIR and TIR be set, because that's how sibling thread matching is done by TCG. spapr's nested-HV capability does not currently coexist with S

From: Philippe Mathieu-Daudé Although the PPC target only supports the TCG and KVM accelerators, QEMU supports more. We can not assume that '!kvm == tcg', so test for the correct accelerator. This also eases code review, because here we don't care about KVM, we really want to test for TCG. Revie
