When building kernels for a preliminary hardware target, having to add a kernel command-line option can prove inconvenient. Add a Kconfig option that changes the default of this option to 1. Signed-off-by: Josh Triplett <josh@xxxxxxxxxxxxxxxx> --- I dropped the indication of the default in the module parameter documentation, but I could also change it to show the default for the current kernel via ifdef. drivers/gpu/drm/Kconfig | 9 +++++++++ drivers/gpu/drm/i915/i915_drv.c | 4 ++-- 2 files changed, 11 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig index a7c54c8..35d57ed 100644 --- a/drivers/gpu/drm/Kconfig +++ b/drivers/gpu/drm/Kconfig @@ -168,6 +168,15 @@ config DRM_I915_KMS the driver to bind to PCI devices, which precludes loading things like intelfb. +config DRM_I915_PRELIMINARY_HW_SUPPORT + bool "Enable preliminary support for prerelease Intel hardware by default" + depends on DRM_I915 + help + Choose this option if you have prerelease Intel hardware and want the + i915 driver to support it by default.
