From: Gaurav K Singh <[email protected]> commit b4615730530be85fc45ab4631c2ad6d8e2d0b97d upstream.
On Geminilake, sometimes audio card is not getting detected after reboot. This is a spurious issue happening on Geminilake. HW codec and HD audio controller link was going out of sync for which there was a fix in i915 driver but was not getting invoked for GLK. Extending this fix to GLK as well. Tested by Du,Wenkai on GLK board. Bspec: 21829 v2: Instead of checking GEN9_BC, BXT and GLK macros, use IS_GEN9 macro (Jani N) Cc: <[email protected]> # b651bd2a3ae3 ("drm/i915/audio: Fix audio enumeration issue on BXT") Cc: <[email protected]> Signed-off-by: Gaurav K Singh <[email protected]> Reviewed-by: Abhay Kumar <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit 8221229046e862977ae93ec9d34aa583fbd10397) Signed-off-by: Joonas Lahtinen <[email protected]> Signed-off-by: Liwei Song <[email protected]> --- drivers/gpu/drm/i915/intel_audio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_audio.c b/drivers/gpu/drm/i915/intel_audio.c index b6a0d39d81be..96fa2c0e7345 100644 --- a/drivers/gpu/drm/i915/intel_audio.c +++ b/drivers/gpu/drm/i915/intel_audio.c @@ -715,7 +715,7 @@ static void i915_audio_component_codec_wake_override(struct device *kdev, struct drm_i915_private *dev_priv = kdev_to_i915(kdev); u32 tmp; - if (!IS_GEN9_BC(dev_priv)) + if (!IS_GEN9(dev_priv)) return; i915_audio_component_get_power(kdev); -- 2.7.4 -- _______________________________________________ linux-yocto mailing list [email protected] https://lists.yoctoproject.org/listinfo/linux-yocto
