[edk2-devel] [PATCH v1 0/3] Add support for handling SGI and pending interrupts

["Kun Qin" <kuqin12@gmail.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4466

This patch series introduce a few improvements related to interrupt
handling for ArmGic driver and library.

1. The current implementation of the `ArmGicSendSgiTo` is based on GIC v2
and does not work on GIC v3 and on.
2. The pending interrupt related primitives does not exist for end users.

The change added the SGI support compatible with GIC v3 and v4. A few
pending interrupt related utility functions were also added.

This change was tested on QEMU, FVP and proprietary hardware platforms.
