From bc4d91f699d8529682be34e9f61be87679982f9b Mon Sep 17 00:00:00 2001 From: Akash Goel Date: Thu, 26 Feb 2015 16:09:47 +0530 Subject: [PATCH] drm/i915: Removed the read of RP_STATE_CAP from sysfs/debugfs functions The frequency values(Rp0, Rp1, Rpn) reported by RP_STATE_CAP register are stored, initially by the Driver, inside the dev_priv->rps structure. Since these values are expected to remain same throughout, there is no real need to read this register, on dynamic basis, from certain debugfs/sysfs functions and the values can be instead retrieved from the dev_priv->rps structure when needed. For the i915_frequency_info debugfs interface, the frequency values from the RP_STATE_CAP register only should be used, to indicate the actual Hw state, since it is principally used for the debugging purpose. v2: Reverted the changes in i915_frequency_info function, to continue report back the frequency values, as per the actual Hw state (Chris) Signed-off-by: Akash Goel Reviewed-by: Chris Wilson Signed-off-by: Daniel Vetter --- Reading git-format-patch failed
