LoPAPR defines a "ibm,pa-features" per-CPU device tree property which describes extended features of the Processor Architecture. This adds the property to the device tree.

This removes unused POWERPC_MMU_2_06a/POWERPC_MMU_2_06d. This replaces POWERPC_MMU_64B with POWERPC_MMU_2_03 for POWER5+ to be more explicit about the version of the PowerISA supported. This defines POWERPC_MMU_2_07 and uses it for the POWER8 CPU family. This will not have an immediate effect now but it will in the following patch. This should cause no behavioural change.

The core VFIO infrastructure more or less allows VFIO devices to work on any normal guest PCI host bridge (PHB) without extra logic. However, the "spapr-pci-host-bridge" device (as opposed to the special "spapr-pci-vfio-host-bridge" device) breaks this by using a partially KVM accelerated implementation of the guest kernel IOMMU which won't work with VFIO devices, without additional kernel support. This patch allows VFIO devices to work on the spapr-pci-host-bridge, by having it switch off KVM TCE acceleration when a VFIO device is added to the PHB (either on startup, or by hotplug).

Because of the way non-VFIO guest IOMMU operations are KVM accelerated, not all TCE tables (guest IOMMU contexts) can support VFIO devices. Currently, this is decided at creation time. To support hotplug of VFIO devices, we need to allow a TCE table which previously didn't allow VFIO devices to be switched so that it can. This patch adds an spapr_tce_set_need_vfio() function to do this, by reallocating the table in userspace if necessary. Currently this doesn't allow the KVM acceleration to be re-enabled if all the VFIO devices are removed. That's an optimization for another time.

由 David Gibson 提交于
The vfio_accel parameter used when creating a new TCE table (guest IOMMU context) has a confusing name. What it really means is whether we need the TCE table created to be able to support VFIO devices. VFIO is relevant, because when available we use in-kernel acceleration of the TCE table, but that may not work with VFIO devices because updates to the table are handled in kernel, bypass qemu and so don't hit qemu's infrastructure for keeping the VFIO host IOMMU state in sync with the guest IOMMU state. Rename the parameter to "need_vfio" throughout. This is a cosmetic change, with no impact on the logic.

At present the PCI host bridge (PHB) for the pseries machine type has a fixed DMA window from 0..1GB (in PCI address space) which is mapped to real memory via the PAPR paravirtualized IOMMU. For better support of VFIO devices, we're going to want to allow for different configurations of the DMA window. Eventually we'll want to allow the guest itself to reconfigure the window via the PAPR dynamic DMA window interface, but as a preliminary this patch allows the user to reconfigure the window with new properties on the PHB device.

According to a commit message in the Linux kernel (see here https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b60c31d85a2a for example), the name of the property that carries the information about the number of SLB entries should be called "slb-size", and not "ibm,slb-size". The Linux kernel can deal with both names, but to be on the safe side we should support the official name, too.

Terminate the guest when HTAB of requested size isn't allocated by the host. When memory hotplug is attempted on a guest that has booted with less than requested HTAB size, the guest kernel will not be able to gracefully fail the hotplug request. This patch will ensure that we never end up in a situation where memory hotplug fails due to less than requested HTAB size.

Commit 4d00636e ("ich9: Add the lpc chip", Nov 14 2012) added the ich9_apm_ctrl_changed() ioport write callback function such that it would inject the SMI, in response to a write to the APM_CNT register, on the first CPU, invariably. Since this register is used by guest code to trigger an SMI synchronously, the interrupt should be injected on the VCPU that is performing the write. apm_ioport_writeb() is the .write callback of the "apm_ops" MemoryRegionOps [hw/isa/apm.c]; it is parametrized to call ich9_apm_ctrl_changed() by ich9_lpc_init() [hw/isa/lpc_ich9.c], via apm_init(). Therefore this change affects no other board. ich9_generate_smi() is an unrelated function that is called by the TCO watchdog; a watchdog is likely in its right to (asynchronously) inject interrupts on the first CPU only. This patch allows the combined edk2/OVMF SMM driver stack to work with multiple VCPUs on TCG, using both qemu-system-i386 and qemu-system-x86_64.

When a live migration is started the log address to mark dirty pages is provided to the vhost backend through the vhost_dev_set_log function. This function is called for each queue pairs but the queue index is wrongly set: always set to the first queue pair. Then vhost backend lost descriptor addresses of the queue pairs greater than 1 and behaviour of the vhost backend is unpredictable. The queue index is computed by taking account of the vq_index (to retrieve the queue pair index) and calling the vhost_get_vq_index method of the backend.
