diff --git a/exec.c b/exec.c index 8a3f621..c366835 100644 --- a/exec.c +++ b/exec.c @@ -2542,6 +2542,7 @@ void cpu_register_physical_memory_log(target_phys_addr_t start_addr, p->region_offset = 0; } else { p->phys_offset = phys_offset; + p->region_offset = region_offset; if ((phys_offset & ~TARGET_PAGE_MASK) <= IO_MEM_ROM || (phys_offset & IO_MEM_ROMD)) phys_offset += TARGET_PAGE_SIZE;
cpu_register_physical_memory_log() does not update region_offset if a page was previously registered for the same address. This could cause mmio accesses going to the wrong place, by using the old region_offset. Signed-off-by: Avi Kivity <avi@redhat.com> --- exec.c | 1 + 1 files changed, 1 insertions(+), 0 deletions(-)
