2009-08-27kvm: Simplify cpu_synchronize_state()Avi Kivity
cpu_synchronize_state() is a little unreadable since the 'modified' argument isn't self-explanatory. Simplify it by making it always synchronize the kernel state into qemu, and automatically flush the registers back to the kernel if they've been synchronized on this exit.

2009-08-24cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signalNathan Froyd
handle_cpu_signal is very nearly copy-paste code for each target, with a few minor variations. This patch sets up appropriate defaults for a generic handle_cpu_signal and provides overrides for particular targets that did things differently. Fixing things like the persistent (XXX: use sigsetjmp) should now become somewhat easier. Previous comments on this patch suggest that the "activate soft MMU for this block" comments refer to defunct functionality. I have removed such blocks for the appropriate targets in this patch.

According to PPC440 user manual, PPC 440 supports ``mftb'' even it's a preserved instruction: PPC440_UM2013.pdf, p.445, table A-3 when I compile a kernel (2.6.30, bamboo_defconfig/440EP & canyonlands/460EX), I can see ``mftb'' by using ppc-xxx-objdump vmlinux I have also checked the ppc 440x[456], 460S, 464, they also should support mftb.

2009-07-12target-ppc: fix evmergelo and evmergelohiNathan Froyd
For 32-bit PPC targets, we translated: evmergelo rX, rX, rY as: rX-lo = rY-lo rX-hi = rX-lo which is wrong, because we should be transferring rX-lo first. This problem is fixed by swapping the order in which we write the parts of rX. Similarly, we translated: evmergelohi rX, rX, rY as: rX-lo = rY-hi rX-hi = rX-lo In this case, we can't swap the assignment statements, because that would just cause problems for: evmergelohi rX, rY, rX Instead, we detect the first case and save rX-lo in a temporary variable: tmp = rX-lo rX-lo = rY-hi rX-hi = tmp These problems don't occur on PPC64 targets because we don't split the SPE registers into hi/lo parts for such targets.

2009-06-23target-ppc: permit linux-user to read PVRNathan Froyd
Access to the PVR SPR is normally forbidden from userspace apps. The Linux kernel, however, fixes up reads in the appropriate trap handler. To permit applications that read PVR to run on QEMU, then, we need to implement the same handling of PVR reads.

2009-05-22kvm: Add missing bits to support live migrationJan Kiszka
This patch adds the missing hooks to allow live migration in KVM mode. It adds proper synchronization before/after saving/restoring the VCPU states (note: PPC is untested), hooks into cpu_physical_memory_set_dirty_tracking() to enable dirty memory logging at KVM level, and synchronizes that drity log into QEMU's view before running ram_live_save().

2009-03-13Make the ELF loader aware of backwards compatibilityblueswir1
Most 64 bit architectures I'm aware of support running 32 bit code of the same architecture as well. So x86_64 can run i386 code easily and ppc64 can run ppc code. Unfortunately, the current checks are pretty strict. So you can only load e.g. an x86_64 elf binary on qemu-system-x86_64, but no i386 one. This can get really annoying. I first encountered this issue with my multiboot patch, where qemu-system-x86_64 was unable to load an i386 elf binary because the elf loader rejected it. The same thing happened again on PPC64 now. The firmware we're loading is a PPC32 elf binary, as it's shared with PPC32. But the platform is PPC64. Right now there is a hack for this in the ppc cpu.h definition, that simply sets the type to PPC32 in system emulation mode. While that works fine for the firmware, it's no good if you also want to load a PPC64 kernel with -kernel. So in order to solve this mess, I figured the easiest way is to make the elf loader aware of platforms that are backwards compatible. For now I was only sure that x86_64 does i386 and ppc64 does ppc32, but maybe there are other combinations too. This patch is a prerequisite for having a working -kernel option on PPC64.

SPE) registers and the code would claim it had zero width. The QEMU GDB stub code would then return an E14 to GDB, which would complain about not being sure whether p packets were supported or not.
