A bit belated. You could just put WARN_ON(dev_priv->gt.awake) in i915_gem_resume() to mirror the assertions that we are idle on suspend. > > Cc: Chris Wilson <ch...@chris-wilson.co.uk> > Cc: Mika Kuoppala <mika.kuopp...@intel.com> > Signed-off-by: Imre Deak <imre.d...@intel.com> > --- > drivers/gpu/drm/i915/intel_lrc.c | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/drivers/gpu/drm/i915/intel_lrc.c > b/drivers/gpu/drm/i915/intel_lrc.c > index ee4aaf1..ae46345 100644 > --- a/drivers/gpu/drm/i915/intel_lrc.c > +++ b/drivers/gpu/drm/i915/intel_lrc.c > @@ -2158,6 +2158,8 @@ void intel_lr_context_resume(struct drm_i915_private > *dev_priv) > if (WARN_ON(IS_ERR(reg))) > continue; > > + WARN_ON(!execlists_elsp_idle(engine)); I don't think this check here documents the assumption of touching the context. What you want is this assertion in suspend. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
