From 49776d30aea903fb2f9966c8e9b6f23ae5f7c937 Mon Sep 17 00:00:00 2001 From: Kazunori Asayama Date: Fri, 20 Jul 2007 21:39:30 +0200 Subject: [CELL] spufs: Avoid unexpectedly restaring MFC during context save The current SPU context saving procedure in SPUFS unexpectedly restarts MFC when halting decrementer, because MFC_CNTL[Dh] is set without MFC_CNTL[Sm]. This bug causes, for example, saving broken DMA queues. Here is a patch to fix the problem.
