Bspec says we shouldn't enable IPS on BDW when the pipe pixel rate exceeds 95% of the core display clock. Apparently this can cause underruns. There's no similar restriction listed for HSW, so leave that one alone for now. v2: Add pipe_config_supports_ips() (Chris) v3: Compare against the max cdclk insted of the current cdclk v4: Rebased to the latest v5: Rebased to the latest v6: Fix for patch style problems Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=83497Tested-by: NTimo Aaltonen <tjaalton@ubuntu.com> Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: NMika Kahola <mika.kahola@intel.com> Reviewed-by: NDamien Lespiau <damien.lespiau@intel.com> Signed-off-by: NJani Nikula <jani.nikula@intel.com>
