2009-12-03target-ppc: Get MMU state on register syncAlexander Graf
While x86 only needs to sync cr0-4 to know all about its MMU state and enable qemu to resolve virtual to physical addresses, we need to sync all of the segment registers on PPC to know which mapping we're in. So let's grab the segment register contents to be able to use the "x" monitor command and also enable the gdbstub to resolve virtual addresses.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-08-27kvm: Simplify cpu_synchronize_state()Avi Kivity
cpu_synchronize_state() is a little unreadable since the 'modified' argument isn't self-explanatory.

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().
