From b460b8bf23633195535006b29e14c615f888fa24 Mon Sep 17 00:00:00 2001 From: Soby Mathew Date: Tue, 27 May 2014 16:54:31 +0100 Subject: [PATCH] Pass 'cookie' parameter to interrupt handler in BL3-1 The interrupt handling routine in BL3-1 expects a cookie as its last parameter which was not being passed when invoking the interrupt handler in BL3-1. This patch fixes that by passing a dummy cookie parameter in the x3 register. Fixes ARM-software/tf-issues#171 Change-Id: Ic98abbbd9f849e6f1c55343e865b5e0a4904a1c5 --- bl31/aarch64/runtime_exceptions.S | 3 +++ 1 file changed, 3 insertions(+) diff --git a/bl31/aarch64/runtime_exceptions.S b/bl31/aarch64/runtime_exceptions.S index e3673f0d..97ca956d 100644 --- a/bl31/aarch64/runtime_exceptions.S +++ b/bl31/aarch64/runtime_exceptions.S @@ -125,6 +125,9 @@ /* Restore the reference to the 'handle' i.e. SP_EL3 */ mov x2, x20 + /* x3 will point to a cookie (not used now) */ + mov x3, xzr + /* Call the interrupt type handler */ blr x21 -- 2.30.2
