In case of BP_STOP_BEFORE_ACCESS watchpoint check_watchpoint intends to signal EXCP_DEBUG exception on exit from cpu loop, but later overwrites exception code by the cpu_resume_from_signal call. Use cpu_loop_exit with BP_STOP_BEFORE_ACCESS watchpoints. Signed-off-by: NMax Filippov <jcmvbkbc@gmail.com>

由 Benjamin Herrenschmidt 提交于
The virtio config area in PIO space is a bit special. The initial header is little endian but the rest (device specific) is guest native endian. The PIO accessors for PCI on machines that don't have native IO ports assume that all PIO is little endian, which works fine for everything except the above. A complicated way to fix it would be to split the BAR into two memory regions with different endianess settings, but this isn't practical to do, besides, the PIO code doesn't honor region endianness anyway (I have a patch for that too but it isn't necessary at this stage). So I decided to go for the quick fix instead which consists of reverting the swap in virtio-pci in selected places, hoping that when we eventually do a "v2" of the virtio protocols, we sort that out once and for all using a fixed endian setting for everything.

Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: NAvi Kivity <avi@redhat.com>

Commit 95c318f5 (Fix segfault in mmio subpage handling code.) prevented a segfault by making all subpage registrations over an existing memory page perform an unassigned access. Symptoms were writes not taking effect and reads returning zero. Very small page sizes are not currently supported either, so subpage memory areas cannot fully be avoided. Therefore change the previous fix to use a new IO_MEM_SUBPAGE_RAM instead of IO_MEM_UNASSIGNED. Suggested by Avi.
