We've never actually enabled or unmasked the GSE interrupt on BDW+,
even though the interrupt handler was always prepared for it.
Let's enable it and see what happens.
Credit to Mark Kettenis who fixed this in the OpenBSD fork of the
driver. He reports that it fixed the "ACPI _BCM/_BCQ-based
brightness mechanism on a MacBookPro12,1 and a 3rd gen Lenovo X1
Carbon" for them.

I think this hasn't been such a big issue for us because we've mostly moved on to native backlight, which is not affected.

No, not at this moment. As you have pointed, we should be using the native interface instead of the ACPI one for those machines.

With that, FWIW, this *is* needed if you want ACPI-based backlight control to work. On Linux you probably don't notice, since "hardware" backlight control is preferred over "firmware" or "platform" backlight control. It would help me if this did land in the Linux tree though, as it will make future imports of the i915 driver into OpenBSD easier. > > drivers/gpu/drm/i915/i915_irq.c | 2 ++ > > 1 file changed, 2 insertions(+) > > > > diff --git a/drivers/gpu/drm/i915/i915_irq.c b/drivers/gpu/drm/i915/i915_irq.c > > index f0d941455bed..4c271ea267bb 100644 > > --- a/drivers/gpu/drm/i915/i915_irq.c > > +++ b/drivers/gpu/drm/i915/i915_irq.c > > @@ -3799,6 +3799,7 @@ static void gen8_de_irq_postinstall(struct drm_i915_private *dev_priv) > > uint32_t de_pipe_enables; > > u32 de_port_masked = GEN8_AUX_CHANNEL_A; > > u32 de_port_enables; > > + u32 de_misc_masked = GEN8_DE_MISC_GSE; > > enum pipe pipe; > > > > if (INTEL_INFO(dev_priv)->gen >= 9) { > > @@ -3834,6 +3835,7 @@ static void gen8_de_irq_postinstall(struct drm_i915_private *dev_priv) > > de_pipe_enables); > > > > GEN5_IRQ_INIT(GEN8_DE_PORT_, ~de_port_masked, de_port_enables); > > + GEN5_IRQ_INIT(GEN8_DE_MISC_, ~de_misc_masked, de_misc_masked); > > } > > > > static int gen8_irq_postinstall(struct drm_device *dev) > > -- > Jani Nikula, Intel Open Source Technology Center > > [-- Attachment #2: Type: text/plain, Size: 160 bytes --] _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx ^ permalink raw reply [flat|nested] 11+ messages in thread
