2024-10-31pci-ids.rst: add Red Hat pci-id for RISC-V IOMMU deviceDaniel Henrique Barboza1-0/+2
The RISC-V IOMMU PCI device we're going to add next is a reference implementation of the riscv-iommu spec [1], which predicts that the IOMMU can be implemented as a PCIe device. However, RISC-V International (RVI), the entity that ratified the riscv-iommu spec, didn't bother assigning a PCI ID for this IOMMU PCIe implementation that the spec predicts. This puts us in an uncommon situation because we want to add the reference IOMMU PCIe implementation but we don't have a PCI ID for it. Given that RVI doesn't provide a PCI ID for it we reached out to Red Hat and Gerd Hoffman, and they were kind enough to give us a PCI ID for the RISC-V IOMMU PCI reference device. Thanks Red Hat and Gerd for this RISC-V IOMMU PCIe device ID.

2024-10-11docs: use consistent markup for footnotesPaolo Bonzini1-2/+2
Unfortunately, the definition of the footnote syntax requires the author to use the awkward escaped space "\ " in the really common case of "footnote marker at end of word or sentence"; and in fact the rST documentation's examples of footnote syntax contain only artificial examples that do *not* use the syntax. This resulted in ugly rendering of footnotes throughout QEMU's documentation. Ensure the space is escaped whenever the footnote must attach to the preceding word, and also use a named reference for clarity.

2024-10-11docs: avoid footnotes consisting of just URLsPaolo Bonzini1-13/+12
Replace the footnotes with inline links whenever the footnote text consists of nothing but the URL. While at it, make the link texts consistent in the surrounding areas, for example avoiding usage of "here" for the link's text. In the case of acpi-bits.rst this fixes a build failure with Sphinx 8.1.0, because the FOSDEM link was duplicated in the paragraph and the new version is a lot stricter about unreferenced footnotes.

2024-07-22hw/acpi: Update ACPI GED framework to support vCPU HotplugSalil Mehta1-1/+2
ACPI GED (as described in the ACPI 6.4 spec) uses an interrupt listed in the _CRS object of GED to intimate OSPM about an event. Later then demultiplexes the notified event by evaluating ACPI _EVT method to know the type of event. Use ACPI GED to also notify the guest kernel about any CPU hot(un)plug events. Note, GED interface is used by many hotplug events like memory hotplug, NVDIMM hotplug and non-hotplug events like system power down event. Each of these can be selected using a bit in the 32 bit GED IO interface. A bit has been reserved for the CPU hotplug event. ACPI CPU hotplug related initialization should only happen if ACPI_CPU_HOTPLUG support has been enabled for particular architecture. Add cpu_hotplug_hw_init() stub to avoid compilation break.

2024-07-22Add support for RAPL MSRs in KVM/QemuAnthony Harivel2-0/+156
Starting with the "Sandy Bridge" generation, Intel CPUs provide a RAPL interface (Running Average Power Limit) for advertising the accumulated energy consumption of various power domains (e.g. CPU packages, DRAM, etc.). The consumption is reported via MSRs (model specific registers) like MSR_PKG_ENERGY_STATUS for the CPU package power domain. These MSRs are 64 bits registers that represent the accumulated energy consumption in micro Joules. They are updated by microcode every ~1ms. For now, KVM always returns 0 when the guest requests the value of these MSRs. Use the KVM MSR filtering mechanism to allow QEMU handle these MSRs dynamically in userspace. To limit the amount of system calls for every MSR call, create a new thread in QEMU that updates the "virtual" MSR values asynchronously. Each vCPU has its own vMSR to reflect the independence of vCPUs. The thread updates the vMSR values with the ratio of energy consumed of the whole physical CPU package the vCPU thread runs on and the thread's utime and stime values. All other non-vCPU threads are also taken into account. Their energy consumption is evenly distributed among all vCPUs threads running on the same physical CPU package. To overcome the problem that reading the RAPL MSR requires priviliged access, a socket communication between QEMU and the qemu-vmsr-helper is mandatory. You can specified the socket path in the parameter. This feature is activated with -accel kvm,rapl=true,path=/path/sock.sock Actual limitation: - Works only on Intel host CPU because AMD CPUs are using different MSR adresses. - Only the Package Power-Plane (MSR_PKG_ENERGY_STATUS) is reported at the moment.
