If the GPU load is low enough, it's possible that we'll be stuck at idle frequency rather than transition into softmin frequency requested by userspace. v2: Use intel_set_rps, drop vlv_set_idle v3: Back to vlv_set_idle, clamp to valid range v4: Place intel_set_rps at the end References: https://bugs.freedesktop.org/show_bug.cgi?id=89728 Cc: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Cc: Imre Deak <imre.deak@xxxxxxxxx> Cc: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Reviewed-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Signed-off-by: Michał Winiarski <michal.winiarski@xxxxxxxxx> --- drivers/gpu/drm/i915/intel_pm.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_pm.c b/drivers/gpu/drm/i915/intel_pm.c index 658a756..c94521cc 100644 --- a/drivers/gpu/drm/i915/intel_pm.c +++ b/drivers/gpu/drm/i915/intel_pm.c @@ -4844,6 +4844,12 @@ void gen6_rps_busy(struct drm_i915_private *dev_priv) gen6_rps_reset_ei(dev_priv); I915_WRITE(GEN6_PMINTRMSK, gen6_rps_pm_mask(dev_priv, dev_priv->rps.cur_freq)); + + /* Ensure we start at the user's desired frequency */ + intel_set_rps(dev_priv, + clamp(dev_priv->rps.cur_freq, + dev_priv->rps.min_freq_softlimit, + dev_priv->rps.max_freq_softlimit)); } mutex_unlock(&dev_priv->rps.hw_lock); } -- 2.8.0 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
