From 1f64643aa5f5a17f1723f7ea0f17b7a3a8f632b3 Mon Sep 17 00:00:00 2001 From: Luke Browning Date: Thu, 5 Jun 2008 17:30:25 +0800 Subject: powerpc/spufs: remove class_0_dsisr from spu exception handling According to the CBEA, the SPU dsisr is not updated for class 0 exceptions. spu_stopped() is testing the dsisr that was passed to it from the class 0 exception handler, so we return a false positive here. This patch cleans up the interrupt handler and erroneous tests in spu_stopped. It also removes the fields from the csa since it is not needed to process class 0 events.
