Hi all, Could more GPU people besides Alex take a look on this. I'd want to make progress with this series within this cycle but would prefer to have Acks from GPU side. > > > - select ACPI_WMI if ACPI && X86 > > > + select ACPI_WMI if ACPI > > > help > > > Choose this option if you have a recent AMD Radeon graphics card. > > > > > > diff --git a/drivers/gpu/drm/gma500/Kconfig > > > b/drivers/gpu/drm/gma500/Kconfig index a2acaa699dd5..dc4c56638819 > > > 100644 > > > --- a/drivers/gpu/drm/gma500/Kconfig > > > +++ b/drivers/gpu/drm/gma500/Kconfig > > > @@ -11,7 +11,6 @@ config DRM_GMA500 > > > select ACPI_VIDEO if ACPI > > > select BACKLIGHT_CLASS_DEVICE if ACPI > > > select INPUT if ACPI > > > - select X86_PLATFORM_DEVICES if ACPI > > > select ACPI_WMI if ACPI > > > help > > > Say yes for an experimental 2D KMS framebuffer driver for the > > > diff -- > > > git a/drivers/gpu/drm/i915/Kconfig b/drivers/gpu/drm/i915/Kconfig index > > > 5e939004b646..71426b9c91f0 100644 > > > --- a/drivers/gpu/drm/i915/Kconfig > > > +++ b/drivers/gpu/drm/i915/Kconfig > > > @@ -28,7 +28,6 @@ config DRM_I915 > > > # but for select to work, need to select ACPI_VIDEO's dependencies, > > > ick > > > select BACKLIGHT_CLASS_DEVICE if ACPI > > > select INPUT if ACPI > > > - select X86_PLATFORM_DEVICES if ACPI > > > select ACPI_WMI if ACPI > > > select ACPI_VIDEO if ACPI > > > select SYNC_FILE > > > diff --git a/drivers/gpu/drm/radeon/Kconfig > > > b/drivers/gpu/drm/radeon/Kconfig index c479f0c0dd5c..3cd70aef770e > > > 100644 > > > --- a/drivers/gpu/drm/radeon/Kconfig > > > +++ b/drivers/gpu/drm/radeon/Kconfig > > > @@ -25,9 +25,7 @@ config DRM_RADEON > > > # ACPI_VIDEO's dependencies must also be selected. > > > select INPUT if ACPI > > > select ACPI_VIDEO if ACPI > > > - # On x86 ACPI_VIDEO also needs ACPI_WMI > > > - select X86_PLATFORM_DEVICES if ACPI && X86 > > > - select ACPI_WMI if ACPI && X86 > > > + select ACPI_WMI if ACPI > > > help > > > Choose this option if you have an ATI Radeon graphics card. > > > There > > > are both PCI and AGP versions.
