In the later patch, it will be used to construct NVDIMM ACPI _FIT method which reflects the presented nvdimm devices after nvdimm hotplug As FIT buffer can not completely mapped into guest address space, OSPM will exit to QEMU multiple times, however, there is the race condition - FIT may be changed during these multiple exits, so that some rules are introduced: 1) the user should hold the @lock to access the buffer and 2) mark @dirty whenever the buffer is updated. @dirty is cleared for the first time OSPM gets fit buffer, if dirty is detected in the later access, OSPM will restart the access As fit should be updated after nvdimm device is successfully realized so that a new hotplug callback, post_hotplug, is introduced Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.

2016-10-21xen_platform: unplug also SCSI disksOlaf Hering
Using 'vdev=sd[a-o]' will create an emulated LSI controller, which can be used by the emulated BIOS to boot from disk. If the HVM domU has also PV driver the disk may appear twice in the guest. To avoid this an unplug of the emulated hardware is needed, similar to what is done for IDE and NIC drivers already. Since the SCSI controller provides only disks the entire controller can be unplugged at once. Impact of the change for classic and pvops based guest kernels: vdev=sda:disk0 before: pvops: disk0=pv xvda + emulated sda classic: disk0=pv sda + emulated sdq after: pvops: disk0=pv xvda classic: disk0=pv sda vdev=hda:disk0, vdev=sda:disk1 before: pvops: disk0=pv xvda disk1=emulated sda classic: disk0=pv hda disk1=pv sda + emulated sdq after: pvops: disk0=pv xvda disk1=not accessible by blkfront, index hda==index sda classic: disk0=pv hda disk1=pv sda vdev=hda:disk0, vdev=sda:disk1, vdev=sdb:disk2 before: pvops: disk0=pv xvda disk1=emulated sda disk2=pv xvdb + emulated sdb classic: disk0=pv hda disk1=pv sda + emulated sdq disk2=pv sdb + emulated sdr after: pvops: disk0=pv xvda disk1=not accessible by blkfront, index hda==index sda disk2=pv xvdb classic: disk0=pv hda disk1=pv sda disk2=pv sda Signed-off-by: Olaf Hering <olaf@aepfle.de> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org> Signed-off-by: Stefano Stabellini <sstabellini@kernel.org>

2016-10-17intel_iommu: reject broken EIMRadim Krčmář
Cluster x2APIC cannot work without KVM's x2apic API when the maximal APIC ID is greater than 8 and only KVM's LAPIC can support x2APIC, so we forbid other APICs and also the old KVM case with less than 9, to simplify the code. There is no point in enabling EIM in forbidden APICs, so we keep it enabled only for the KVM APIC; unconditionally, because making the option depend on KVM version would be a maintanance burden. Old QEMUs would enable eim whenever intremap was on, which would trick guests into thinking that they can enable cluster x2APIC even if any interrupt destination would get clamped to 8 bits. Depending on your configuration, QEMU could notice that the destination LAPIC is not present and report it with a very non-obvious: KVM: injection failed, MSI lost (Operation not permitted) Or the guest could say something about unexpected interrupts, because clamping leads to aliasing so interrupts were being delivered to incorrect VCPUs. KVM_X2APIC_API is the feature that allows us to enable EIM for KVM. QEMU 2.7 allowed EIM whenever interrupt remapping was enabled. In order to keep backward compatibility, we again allow guests to misbehave in non-obvious ways, and make it the default for old machine types. A user can enable the buggy mode it with "x-buggy-eim=on".

2016-09-29block-backend: remove blk_flush_allJohn Snow
We can teach Xen to drain and flush each device as it needs to, instead of trying to flush ALL devices. This removes the last user of blk_flush_all. The function is therefore removed under the premise that any new uses of blk_flush_all would be the wrong paradigm: either flush the single device that requires flushing, or use an appropriate flush_all mechanism from outside of the BlkBackend layer.

2016-09-27cpus: pass CPUState to run_on_cpu helpersAlex Bennée
CPUState is a fairly common pointer to pass to these helpers. This means if you need other arguments for the async_run_on_cpu case you end up having to do a g_malloc to stuff additional data into the routine. For the current users this isn't a massive deal but for MTTCG this gets cumbersome when the only other parameter is often an address. This adds the typedef run_on_cpu_func for helper functions which has an explicit CPUState * passed as the first parameter. All the users of run_on_cpu and async_run_on_cpu have had their helpers updated to use CPUState where available.

2016-09-27intel_iommu, amd_iommu: allow UNMAP notifiersPeter Xu
x86 vIOMMUs still lack of a complete IOMMU notifier mechanism. Before that is achieved, let's open a door for vhost DMAR support, which only requires cache invalidations (UNMAP operations). Meanwhile, convert hw_error() to error_report() and exit(1), to make the error messages cleaner and obvious (no CPU registers will be dumped).

2016-09-24hw/i386: Introduce AMD IOMMUDavid Kiarie
Add AMD IOMMU emulaton to Qemu in addition to Intel IOMMU. The IOMMU does basic translation, error checking and has a minimal IOTLB implementation. This IOMMU bypassed the need for target aborts by responding with IOMMU_NONE access rights and exempts the region 0xfee00000-0xfeefffff from translation as it is the q35 interrupt region. We advertise features that are not yet implemented to please the Linux IOMMU driver. IOTLB aims at implementing commands on real IOMMUs which is essential for debugging and may not offer any performance benefits Signed-off-by: David Kiarie <davidkiarie4@gmail.com> Reviewed-by: Michael S.
