[PULL 19/20] hvf: arm: Emulate ICC_RPR_EL1 accesses properly
Posted by Peter Maydell 3 months, 3 weeks ago
From: Zenghui Yu <zenghui.yu@linux.dev>

Commit a2260983c655 ("hvf: arm: Add support for GICv3") added GICv3 support
by implementing emulation for a few system registers. ICC_RPR_EL1 was
defined but not plugged in the sysreg handlers (for no good reason).

Fix it.
