From 0988eed04e7237fdab524413e9c69bbf54cdf400 Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Thu, 16 Dec 2010 15:37:54 -0500 Subject: [PATCH] - applesmc_update.patch: Make the driver more generic. Should help Apples. - apple_backlight.patch: Make sure that this loads on all hardware. - efifb_update.patch: Fixes for the 11 inch Macbook Air - acpi_reboot.patch: Should make reboot work better on most hardware - efi_default_physical.patch: Some machines dislike EFI virtual mode --- acpi_reboot.patch | 102 ++ apple_backlight.patch | 688 +++++++++++ applesmc_update.patch | 2293 ++++++++++++++++++++++++++++++++++++ config-x86-generic | 2 +- config-x86_64-generic | 2 +- efi_default_physical.patch | 403 +++++++ efifb_update.patch | 217 ++++ kernel.spec | 20 + 8 files changed, 3725 insertions(+), 2 deletions(-) create mode 100644 acpi_reboot.patch create mode 100644 apple_backlight.patch create mode 100644 applesmc_update.patch create mode 100644 efi_default_physical.patch create mode 100644 efifb_update.patch diff --git a/acpi_reboot.patch b/acpi_reboot.patch new file mode 100644 index 000000000..e9fdef35b --- /dev/null +++ b/acpi_reboot.patch @@ -0,0 +1,102 @@ +Improve our reboot handling for compatibility with Windows.
