From 9844d4bf3eb46778f46390d7beee5add650d5fc0 Mon Sep 17 00:00:00 2001 From: Dhinakaran Pandiyan Date: Tue, 21 Aug 2018 15:11:55 -0700 Subject: [PATCH] drm/i915/psr: Add missing check for I915_PSR_DEBUG_IRQ bit We print the last attempted entry and last exit timestamps only when IRQ debug is requested. This check was missed when new debug flags were added in 'commit c44301fce614 ("drm/i915: Allow control of PSR at runtime through debugfs, v6") Fixes: c44301fce614 ("drm/i915: Allow control of PSR at runtime through debugfs, v6") Cc: Maarten Lankhorst Signed-off-by: Dhinakaran Pandiyan Reviewed-by: Maarten Lankhorst Link: https://patchwork.freedesktop.org/patch/msgid/20180821221156.2442-2-dhinakaran.pandiyan@intel.com --- drivers/gpu/drm/i915/i915_debugfs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/i915_debugfs.c b/drivers/gpu/drm/i915/i915_debugfs.c index 26b7e52..374b550 100644 --- a/drivers/gpu/drm/i915/i915_debugfs.c +++ b/drivers/gpu/drm/i915/i915_debugfs.c @@ -2735,7 +2735,7 @@ static int i915_edp_psr_status(struct seq_file *m, void *data) psr_source_status(dev_priv, m); mutex_unlock(&dev_priv->psr.lock); - if (READ_ONCE(dev_priv->psr.debug)) { + if (READ_ONCE(dev_priv->psr.debug) & I915_PSR_DEBUG_IRQ) { seq_printf(m, "Last attempted entry at: %lld\n", dev_priv->psr.last_entry_attempt); seq_printf(m, "Last exit at: %lld\n", -- 2.7.4
