File 0011-PPC-KVM-Disable-mmu-notifier-check.patch of Package qemu-linux-user
From: Alexander Graf <agraf@suse.de> Date: Fri, 6 Jan 2012 01:05:55 +0100 Subject: PPC: KVM: Disable mmu notifier check When using hugetlbfs (which is required for HV mode KVM on 970), we check for MMU notifiers that on 970 can not be implemented properly. So disable the check for mmu notifiers on PowerPC guests, making KVM guests work there, even if possibly racy in some odd circumstances. --- exec.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/exec.c b/exec.c index fc7526666f05d077c8d1a60fcbd6..a50e1488cee832477cb0e44ce360 100644 --- a/exec.c +++ b/exec.c @@ -1242,11 +1242,13 @@ static void *file_ram_alloc(RAMBlock *block, int fd = -1; int64_t page_size; +#ifndef TARGET_PPC if (kvm_enabled() && !kvm_has_sync_mmu()) { error_setg(errp, "host lacks kvm mmu notifiers, -mem-path unsupported"); return NULL; } +#endif for (;;) { fd = open(path, O_RDWR);
