From c158647c107358bf1be579f98e4bb705c1953292 Mon Sep 17 00:00:00 2001 From: Komal Bajaj quic_kbajaj@quicinc.com Date: Tue, 19 Nov 2024 12:16:08 +0530 Subject: [PATCH] EDAC/qcom: Correct interrupt enable register configuration
The previous implementation incorrectly configured the cmn_interrupt_2_enable register for interrupt handling. Using cmn_interrupt_2_enable to configure Tag, Data RAM ECC interrupts would lead to issues like double handling of the interrupts (EL1 and EL3) as cmn_interrupt_2_enable is meant to be configured for interrupts which needs to be handled by EL3.
EL1 LLCC EDAC driver needs to use cmn_interrupt_0_enable register to configure Tag, Data RAM ECC interrupts instead of cmn_interrupt_2_enable.
