From e38e8a0743b0e996a8a3fbea8908fe75a84f02c7 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Fri, 13 Jun 2008 08:28:55 +0800 Subject: Make GPE disable more robust Implemented another change for the GPE disable. We now perform a read-change-write of the enable register instead of simply writing out the cached enable mask. This will prevent inadvertent enabling of GPEs if a rogue GPE is received during initialization (before GPE handlers are installed.) http://bugzilla.kernel.org/show_bug.cgi?id=6217 Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown Signed-off-by: Andi Kleen --- include/acpi/achware.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include') diff --git a/include/acpi/achware.h b/include/acpi/achware.h index d4fb9bbc903..45e985961f4 100644 --- a/include/acpi/achware.h +++ b/include/acpi/achware.h @@ -87,6 +87,8 @@ acpi_status acpi_hw_clear_acpi_status(void); /* * hwgpe - GPE support */ +acpi_status acpi_hw_low_disable_gpe(struct acpi_gpe_event_info *gpe_event_info); + acpi_status acpi_hw_write_gpe_enable_reg(struct acpi_gpe_event_info *gpe_event_info); -- cgit v1.2.3
