<pre>Although that seems too much as a start. Thus it would be nice to get the
non-memory engine(s) reclock first and then deal with memory/timings/etc
This can be done by forcing current code to ignore the memory clock stored in
vbios, i.e.
diff --git a/drm/nv40_pm.c b/drm/nv40_pm.c
index 3af5bcd..0be61db 100644
--- a/drm/nv40_pm.c
+++ b/drm/nv40_pm.c
@@ -191,7 +191,7 @@ nv40_pm_clocks_pre(struct drm_device *dev, struct
nouveau_pm_level *perflvl)
}
/* memory clock */
- if (!perflvl->memory) {
+ if (1) {
info->mpll_ctrl = 0x00000000;
goto out;
}</pre>
