Subject: [PATCH 2/2] EDAC: synopsys: re-enable the interrupts in intr_handler for V3.X Synopsys EDAC DDR
Date: Fri, 18 Mar 2022 19:17:42 +0800 [thread overview]
Message-ID: <20220318111742.15730-3-sherry.sun@nxp.com> (raw)
In-Reply-To: <20220318111742.15730-1-sherry.sun@nxp.com>
Since zynqmp_get_error_info() is called during CE/UE interrupt, at the
end of zynqmp_get_error_info(), it wirtes 0 to ECC_CLR_OFST, which cause
the CE/UE interrupts of V3.X Synopsys EDAC DDR been disabled, then the
interrupt handler will be called only once, so need to re-enable the
interrupts at the end of intr_handler for V3.X Synopsys EDAC DDR.
