From 1cfc0f86eb0348dd04ace8c2171642ebe9cd87bb Mon Sep 17 00:00:00 2001 From: Masato Noguchi Date: Fri, 20 Jul 2007 21:39:37 +0200 Subject: [CELL] spufs: fix decr_status meanings The decr_status in the LSCSA is confusedly used as two meanings: * SPU decrementer was running * SPU decrementer was wrapped as a result of adjust and the code to set decr_status is missing. This patch fixes these problems by using the decr_status argument as a set of flags. This requires a rebuild of the shipped spu_restore code.
