Subject: [PATCH v3 14/17] arm64: dts: realtek: Add EL2 virtual timer interrupt
Date: Sat, 23 May 2026 15:02:39 +0100 [thread overview]
Message-ID: <20260523140242.586031-15-maz@kernel.org> (raw)
In-Reply-To: <20260523140242.586031-1-maz@kernel.org>
The ARMv8.2 based CPUs used in a number of Realtek SoCs are missing
the EL2 virtual timer interrupt. Add it.
Furthermore, the "kent" platform appears to assign PPI9 to both the
EL2 virtual timer and the GIC Maintenance Interrupt, which can't be
right. Attempt a fix by setting the former to PPI12, as PPI9 is
traditionally wired to the GIC itself.
