Each RAM memory region has a unique corresponding RAMBlock. In the current realization, the memory region only stored the ram_addr which means the offset of RAM address space, We need to qurey the global ram.list to find the ram block by ram_addr if we want to get the ram block, which is very expensive. Now, we store the RAMBlock pointer into memory region structure. So, if we know the mr, we can easily get the RAMBlock.

Migration with q35 was not possible before commit 04329029, because q35 unconditionally creates an ich9-ahci device, that was marked as unmigratable. So all q35 machine classes before pc-q35-2.4 were not migratable, so there's no point in keeping compatibility code for them. Remove all old pc-q35 machine classes and keep only pc-q35-2.4 and newer.

In disabled mode, virtio-blk dataplane seems to be enabled, but flow actually goes through the normal virtio path. This patch simplifies a bit the handling of disabled mode. In disabled mode, virtio_blk_handle_output might be called even if s->dataplane is not NULL. This is a bit tricky, because the current check for s->dataplane will always trigger, causing a continuous stream of calls to virtio_blk_data_plane_start. Unfortunately, these calls will not do anything. To fix this, set the "started" flag even in disabled mode, and skip virtio_blk_data_plane_start if the started flag is true. The resulting changes also prepare the code for the next patch, were virtio-blk dataplane will reuse the same virtio_blk_handle_output function as "regular" virtio-blk. Because struct VirtIOBlockDataPlane is opaque in virtio-blk.c, we have to move s->dataplane->started inside struct VirtIOBlock.

This is needed because dataplane will run during block migration as well. The block device migration code is quite liberal in taking the iothread mutex. For simplicity, keep it the same way, even though one could actually choose between the BQL (for regular BlockDriverStates) and the AioContext (for dataplane BlockDriverStates). When the block layer is made fully thread safe, aio_context_acquire shall go away altogether. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Reviewed-by: NMichael S.

For now there are only two dimm's: pc-dimm and nvdimm. This patch is actually needed to disable ballooning on nvdimm. But, to avoid future bugs, instead of disallowing nvdimm, we allow only pc-dimm. So, if someone adds new dimm which should be balloon-able, then this ability should be explicitly specified here. Why ballooning for nvdimm should be disabled for now: NVDIMM for now is planned to use as a backing store for DAX filesystem in the guest and thus this memory is excluded from guest memory management and LRUs. In this case libvirt running QEMU along with configured balloon almost immediately inflates balloon and effectively kill the guest as qemu counts nvdimm as part of the ram. Counting dimm devices as part of the ram for ballooning was started from commit 463756d0: virtio-balloon: Fix balloon not working correctly when hotplug memory Signed-off-by: NVladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Signed-off-by: NDenis V.

Using a CPU type that does not match the host is not possible when using the kvm-hv kernel module - the PVR is checked in the kernel function kvm_arch_vcpu_ioctl_set_sregs_hv() and rejected with -EINVAL if it does not match the host. However, when the user tries to specify a non-matching CPU type, QEMU currently only reports "kvm_init_vcpu failed: Invalid argument", and this is of course not very helpful for the user to solve the problem. So this patch adds a more descriptive error message that tells the user to specify "-cpu host" instead.

Setting the KVM_CAP_PPC_PAPR capability can fail if either the KVM kernel module does not support it, or if the specified vCPU type is not a 64-bit Book3-S CPU type. For example, the user can trigger it easily with "-M pseries -cpu G2leLS" when using the kvm-pr kernel module. So the error should not be reported with cpu_abort() since this function is rather meant for reporting programming errors than reporting user-triggerable errors (it prints out all CPU registers and then calls abort() to kills the program - two things that the normal user does not expect here) . So let's use error_report() with exit(1) here instead. A similar problem exists in the code that sets the KVM_CAP_PPC_EPR capability, so while we're at it, fix that, too.

This hypercall either initializes a page with zeros, or copies another page. According to LoPAPR, the i-cache of the page should also be flushed if using H_ICACHE_INVALIDATE or H_ICACHE_SYNCHRONIZE, and the d-cache should be synchronized to the RAM if the H_ICACHE_SYNCHRONIZE flag is used. For this, two new functions are introduced, kvmppc_dcbst_range() and kvmppc_icbi()_range, which use the corresponding assembler instructions to flush the caches if running with KVM on Power. If the code runs with TCG instead, the code only uses tb_flush(), assuming that this will be enough for synchronization.
