Hi Paolo and Radim,
Here is the second pull request for KVM/ARM for v4.15. These changes
introduce GICv4 support in KVM/ARM, allowing direct injection of LPIs
from devices generating MSIs into VMs. The changes rely on irqchip
infrastructure for GICv4 already merged in tip:irq/core.
The pull request is based on kvm-arm-for-v4.15 plus 722c908f84c6 merged
from tip:irq/core. The diffstat has been trimmed to only show the
changes between the merge base mentioned above and the KVM/ARM side of
GICv4 support, and does not include the additional changes in KVM not
present in tip:irq/core.
I expect that pulling this into the KVM tree after the irq/core changes
land in Linus' tree should result in a clean subsequent pull request
upstream, but let me know if you want me to work this out in some other
way.
The following changes since commit 722c908f84c67bf120105ca870675cadc1bb7b20:
