From: Matthew Garrett Date: Wed, 15 Apr 2009 20:46:36 +0000 (+0100) Subject: ACPI, i915: Register ACPI video even when not modesetting X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b7f0ab460f772b09a9c664d746236a280fec714c;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git ACPI, i915: Register ACPI video even when not modesetting The ACPI video driver defers registration to the i915 driver if the system supports opregion-mediated backlight control. This registration was only being performed in the KMS case. Ensure it's done even if we don't have modesetting enabled. http://bugzilla.kernel.org/show_bug.cgi?id=13048 Signed-off-by: Matthew Garrett Signed-off-by: Len Brown --- diff --git a/drivers/gpu/drm/i915/i915_opregion.c b/drivers/gpu/drm/i915/i915_opregion.c index 69427722d20e..8dc1fd3115c2 100644 --- a/drivers/gpu/drm/i915/i915_opregion.c +++ b/drivers/gpu/drm/i915/i915_opregion.c @@ -370,11 +370,8 @@ int intel_opregion_init(struct drm_device *dev, int resume) if (mboxes & MBOX_ACPI) { DRM_DEBUG("Public ACPI methods supported\n"); opregion->acpi = base + OPREGION_ACPI_OFFSET; - if (drm_core_check_feature(dev, DRIVER_MODESET)) { + if (drm_core_check_feature(dev, DRIVER_MODESET)) intel_didl_outputs(dev); - if (!resume) - acpi_video_register(); - } } else { DRM_DEBUG("Public ACPI methods not supported\n"); err = -ENOTSUPP; @@ -391,6 +388,10 @@ int intel_opregion_init(struct drm_device *dev, int resume) opregion->asle = base + OPREGION_ASLE_OFFSET; } + if (!resume) + acpi_video_register(); + + /* Notify BIOS we are ready to handle ACPI video ext notifs. * Right now, all the events are handled by the ACPI video module. * We don't actually need to do anything with them. */
