2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-10-17Separate migration bitmapJuan Quintela
This patch creates a migration bitmap, which is periodically kept in sync with the qemu bitmap. A separate copy of the dirty bitmap for the migration limits the amount of concurrent access to the qemu bitmap from iothread and migration thread (which requires taking the big lock). We use the qemu bitmap type. We have to "undo" the dirty_pages counting optimization on the general dirty bitmap and do the counting optimization with the migration local bitmap.

2012-10-05cpu_dump_state: move DUMP_FPU and DUMP_CCOP flags from x86-only to genericPeter Maydell
Move the DUMP_FPU and DUMP_CCOP flags for cpu_dump_state() from being x86-specific flags to being generic ones. This allows us to drop some TARGET_I386 ifdefs in various places, and means that we can (potentially) be more consistent across architectures about which monitor commands or debug abort printouts include FPU register contents and info about QEMU's condition-code optimisations.

In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset() was renamed to cpu_state_reset(), to allow introducing a new cpu_reset() that would operate on QOM objects. All callers have been updated except for one in target-mips, so drop all implementations except for the one in target-mips and move the declaration there until MIPSCPU reset can be fully QOM'ified.

2012-03-12cpu-all.h: Don't accidentally sign extend in g2h()Peter Maydell
Cast the argument of the g2h() macro to a target_ulong so that it isn't accidentally sign-extended if it is a signed 32 bit type and long is a 64 bit type. In particular, this fixes a bug where it would return the wrong value for 32 bit guests on 64 bit hosts when passed in one of the arg* values from do_syscall() [which are all abi_long and thus signed types]. This could result in spurious failure of mlock(), among others.

2012-02-18target-i386: Add infrastructure for reporting TPR MMIO accessesJan Kiszka
This will allow the APIC core to file a TPR access report. Depending on the accelerator and kernel irqchip mode, it will either be delivered right away or queued for later reporting. In TCG mode, we can restart the triggering instruction and can therefore forward the event directly. KVM does not allows us to restart, so we postpone the delivery of events recording in the user space APIC until the current instruction is completed. Note that KVM without in-kernel irqchip will report the address after the instruction that triggered the access.
