From: feng.tang on 5 Jul 2010 10:50 From: Feng Tang <feng.tang(a)intel.com> Hi All, Some x86 platforms like intel MID platforms don't have i8042 controllers, and i8042 driver's probe to some non-exist legacy IO ports may hang the MID processor. Current solution for this is add dependency of SERIO_I8042 over !X86_MRST, then if we build a x86 kernel image with X86_MRST=y, it won't have i8042 driver support over common x86 platforms. So we add a i8042 pre-detect hook into x86_platforms ops, so that i8042 driver can use it to run-time judge whether to go on with probe process. Please review these patches. Thanks, Feng Changelog: v2: * only call x86_platforms.i8042_detect() for x86 platforms ---------------- Feng Tang (5): x86: add i8042 pre-detection hook to x86_platform_ops x86, mrst: add i8042_detect API for Moorestwon platform Revert "Input: do not force selecting i8042 on Moorestown" Revert "Input: fixup X86_MRST selects" input: i8042 - add runtime check in x86's i8042_platform_init arch/x86/include/asm/x86_init.h | 2 ++ arch/x86/kernel/mrst.c | 7 +++++++ arch/x86/kernel/x86_init.c | 4 +++- drivers/input/keyboard/Kconfig | 4 ++-- drivers/input/mouse/Kconfig | 2 +- drivers/input/serio/Kconfig | 2 +- drivers/input/serio/i8042-x86ia64io.h | 6 ++++++ 7 files changed, 22 insertions(+), 5 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
