[Qemu-devel] [PATCH 3/3] arm_gic: GICD_ICFGR: Do not force edge-triggered PPIs

[Adam Lackorzynski <adam@os.inf.tu-dresden.de>]

Using GICD_ICFGR for PPIs forces PPIs to edge-triggered mode, although they
have been initialised to level-triggered. This affects all interrupts
covered by the write access. Change the handling of PPIs to not force a
specific mode. It is implementation defined whether setting the mode of PPIs
is supported.
