From 9f403603f29f748b50b85a1be1c2ca2c792ae200 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 18 Jul 2011 16:02:37 +1000 Subject: [PATCH] drm/nv40/pm: parse geometric delta clock from vbios This changes the meaning of what we reported as "core" clock previously. The shader/rop units are allegedly supposed to be run at the base clock listed in the perf table, while the geometric clock can be bumped from this value on some boards. So that we can report both, we'll report the base clock as "shader" (since the shaders *do* run at it), and the geometric clock as "core".
