From 4e22a3bc58e1b911387947b2e0e7a73176dd2d83 Mon Sep 17 00:00:00 2001 From: Tobias Diedrich Date: Mon, 13 Dec 2010 22:39:46 +0100 Subject: Add acpi_get_sleep_type() to i82371eb and P2B _PTS/_WAK methods Build fix for src/arch/i386/boot/acpi.c if !CONFIG_SMP Also check for acpi_slp_type 2 in acpi_is_wakeup, since S2 uses the same acpi wakeup vector as S3. Add _PTS/_WAK methods to turn off/on the CPU/case fans and blink the power LED while sleeping. acpi_get_sleep_type() is in a seperate file i82371eb_wakeup.c because it is used in both romstage and ramstage after patch 3/3, whereas i82371eb_early_pm.c is used only in romstage. I used the name acpi_get_sleep_type instead of acpi_is_wakeup_early because I think acpi_is_wakeup_early is a bit misleading as a name since it doesn't return a boolean value. Other chipsets so far only ever set acpi_slp_type to 0 and 3, so the added check for acpi_slp_type == 2 (resume from S2) should not change behaviour of other boards: northbridge/intel/i945/northbridge.c:256:extern u8 acpi_slp_type; northbridge/intel/i945/northbridge.c:263: acpi_slp_type=0; northbridge/intel/i945/northbridge.c:267: acpi_slp_type=3; northbridge/intel/i945/northbridge.c:271: acpi_slp_type=0; southbridge/intel/i82801gx/i82801gx_lpc.c:171:extern u8 acpi_slp_type; southbridge/via/vt8237r/vt8237r_lpc.c:149:extern u8 acpi_slp_type; southbridge/via/vt8237r/vt8237r_lpc.c:238: acpi_slp_type = ((tmp & (7 << 10)) >> 10) == 1 ? 3 : 0 ; southbridge/via/vt8237r/vt8237r_lpc.c:239: printk(BIOS_DEBUG, "SLP_TYP type was %x %x\n", tmp, acpi_slp_type); Change-Id: I13feff0b8f49aa988e5467cdbef02981f0a6be8a Signed-off-by: Tobias Diedrich Signed-off-by: Patrick Georgi Reviewed-on: http://review.coreboot.org/188 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer --- src/arch/x86/boot/acpi.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'src/arch/x86/boot') diff --git a/src/arch/x86/boot/acpi.c b/src/arch/x86/boot/acpi.c index caf860e6b6..f1be0345e4 100644 --- a/src/arch/x86/boot/acpi.c +++ b/src/arch/x86/boot/acpi.c @@ -481,7 +481,8 @@ u8 acpi_slp_type = 0; static int acpi_is_wakeup(void) { - return (acpi_slp_type == 3); + /* Both resume from S2 and resume from S3 restart at CPU reset */ + return (acpi_slp_type == 3 || acpi_slp_type == 2); } static acpi_rsdp_t *valid_rsdp(acpi_rsdp_t *rsdp) @@ -567,9 +568,11 @@ void *acpi_find_wakeup_vector(void) return wake_vec; } +#if CONFIG_SMP extern char *lowmem_backup; extern char *lowmem_backup_ptr; extern int lowmem_backup_size; +#endif #define WAKEUP_BASE 0x600 @@ -588,12 +591,14 @@ void acpi_jump_to_wakeup(void *vector) return; } +#if CONFIG_SMP // FIXME: This should go into the ACPI backup memory, too.
