2019-09-07PCI: Get rid of dev->has_secondary_link flagMika Westerberg
In some systems, the Device/Port Type in the PCI Express Capabilities register incorrectly identifies upstream ports as downstream ports. d0751b98dfa3 ("PCI: Add dev->has_secondary_link to track downstream PCIe links") addressed this by adding pci_dev.has_secondary_link, which is set for downstream ports. But this is confusing because pci_pcie_type() sometimes gives the wrong answer, and it's not obvious that we should use pci_dev.has_secondary_link instead. Reduce the confusion by correcting the type of the port itself so that pci_pcie_type() returns the actual type regardless of what the Device/Port Type register claims it is. Update the users to call pci_pcie_type() and pcie_downstream_port() accordingly, and remove pci_dev.has_secondary_link completely.

2019-08-28PCI/ACPI: Rename _HPX structs from hpp_* to hpx_*Krzysztof Wilczynski
The names of the hpp_type0, hpp_type1 and hpp_type2 structs suggest that they're related to _HPP, when in fact they're related to _HPX. The struct hpp_type0 denotes an _HPX Type 0 setting record that supersedes the _HPP setting record, and it has been used interchangeably for _HPP as per the ACPI specification (see version 6.3, section 6.2.9.1) which states that it should be applied to PCI, PCI-X and PCI Express devices, with settings being ignored if they are not applicable. Rename them to hpx_type0, hpx_type1 and hpx_type2 to reflect their relation to _HPX rather than _HPP.

2019-07-20KVM: Boost vCPUs that are delivering interruptsWanpeng Li
Inspired by commit 9cac38dd5d (KVM/s390: Set preempted flag during vcpu wakeup and interrupt delivery), we want to also boost not just lock holders but also vCPUs that are delivering interrupts. Most smp_call_function_many calls are synchronous, so the IPI target vCPUs are also good yield candidates. This patch introduces vcpu->ready to boost vCPUs during wakeup and interrupt delivery time; unlike s390 we do not reuse vcpu->preempted so that voluntarily preempted vCPUs are taken into account by kvm_vcpu_on_spin, but vmx_vcpu_pi_put is not affected (VT-d PI handles voluntary preemption separately, in pi_pre_block).

2019-07-20KVM: LAPIC: Inject timer interrupt via posted interruptWanpeng Li
Dedicated instances are currently disturbed by unnecessary jitter due to the emulated lapic timers firing on the same pCPUs where the vCPUs reside. There is no hardware virtual timer on Intel for guest like ARM, so both programming timer in guest and the emulated timer fires incur vmexits. This patch tries to avoid vmexit when the emulated timer fires, at least in dedicated instance scenario when nohz_full is enabled. In that case, the emulated timers can be offload to the nearest busy housekeeping cpus since APICv has been found for several years in server processors. The guest timer interrupt can then be injected via posted interrupts, which are delivered by the housekeeping cpu once the emulated timer fires. The host should tuned so that vCPUs are placed on isolated physical processors, and with several pCPUs surplus for busy housekeeping. If disabled mwait/hlt/pause vmexits keep the vCPUs in non-root mode, ~3% redis performance benefit can be observed on Skylake server, and the number of external interrupt vmexits drops substantially.
