File 0010-PPC-KVM-Disable-mmu-notifier-check.patch of Package qemu
From 5af3522f9a43395d9445806b150c0b9f5a7d107e Mon Sep 17 00:00:00 2001 From: Alexander Graf <agraf@suse.de> Date: Fri, 6 Jan 2012 01:05:55 +0100 Subject: [PATCH] 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 c97ef4a8da..b47b3f9096 100644 --- a/exec.c +++ b/exec.c @@ -1362,11 +1362,13 @@ static void *file_ram_alloc(RAMBlock *block, int fd = -1; int64_t file_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);
