From 2442a8ba5abe2c27c572bc522da1c33df98c6ec7 Mon Sep 17 00:00:00 2001 From: Luke Browning Date: Fri, 6 Jun 2008 11:26:54 +0800 Subject: powerpc/spufs: don't extend time time slice if context is not in spu_run An spu context shouldn't get an extra tick if the time slice code couldn't find something else to run. This means contexts that are not within spu_run (ie, SPU_SCHED_SPU_RUN is cleared) will not receive extra ticks while we have no other contexts waiting.
