The chip data of HDMI LPE audio is set to drm_i915_private which is not
consistent with the expectation by x86 APIC driver. In the case of not
enabling CONFIG_CPUMASK_OFFSTACK, this would cause kernel panic while doing
CPU hotplug. Since the dependency of IRQ chip data was removed from HDMI
LPE audio by Commit 9bd9590997b92fbd79fd028f704f6c584b4439d7 ("drm/i915:
Stop pretending to mask/unmask LPE audio interrupts"), remove the
code of setting IRQ chip data to resolve this issue.Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103731 Cc: Pierre-Louis Bossart <[email protected]> Cc: Jerome Anand <[email protected]> Cc: Takashi Iwai <[email protected]> Signed-off-by: Augustine.Chen <[email protected]> --- drivers/gpu/drm/i915/intel_lpe_audio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_lpe_audio.c b/drivers/gpu/drm/i915/intel_lpe_audio.c index 3bf6528..56176f9 100644 --- a/drivers/gpu/drm/i915/intel_lpe_audio.c +++ b/drivers/gpu/drm/i915/intel_lpe_audio.c @@ -176,7 +176,7 @@ static int lpe_audio_irq_init(struct drm_i915_private *dev_priv) handle_simple_irq, "hdmi_lpe_audio_irq_handler"); - return irq_set_chip_data(irq, dev_priv); + return 0; } static bool lpe_audio_detect(struct drm_i915_private *dev_priv) -- 1.9.1 _______________________________________________ Intel-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/intel-gfx
