From 69ec87efa815d69140423014bb5f91e034faac22 Mon Sep 17 00:00:00 2001 From: Lin Ming Date: Thu, 1 Apr 2010 11:14:12 +0800 Subject: ACPICA: Add subsystem option to force copy of DSDT to local memory Optionally copy the entire DSDT to local memory (instead of simply mapping it.) There are some BIOSs that corrupt or replace the original DSDT, creating the need for this option. Default is FALSE, do not copy the DSDT. https://bugzilla.kernel.org/show_bug.cgi?id=14679 Signed-off-by: Lin Ming Signed-off-by: Bob Moore Signed-off-by: Len Brown --- drivers/acpi/acpica/actables.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'drivers/acpi/acpica/actables.h') diff --git a/drivers/acpi/acpica/actables.h b/drivers/acpi/acpica/actables.h index fc52b6f..b7197bf 100644 --- a/drivers/acpi/acpica/actables.h +++ b/drivers/acpi/acpica/actables.h @@ -109,6 +109,8 @@ acpi_tb_verify_checksum(struct acpi_table_header *table, u32 length); void acpi_tb_check_dsdt_header(void); +void acpi_tb_copy_dsdt(struct acpi_table_desc *table_desc); + void acpi_tb_install_table(acpi_physical_address address, char *signature, u32 table_index); -- cgit v1.1
