From 454625c5cf4adecb5b80777503bc600c8b139004 Mon Sep 17 00:00:00 2001 From: Kayalvizhi Dhandapani Date: Tue, 7 Oct 2014 14:34:01 -0400 Subject: intel/fsp_baytrail: Fix SMM/SMI With SMM enabled the boot stopped while patching up global NVS in DSDT. The cause is that both CPUs are assigned the same SMBASE address. So update the "cpu_smm_do_relocation()" function so that each CPU gets a different SMBASE address Based on rmodule work that wasn't propagated to the FSP version: commit 3eb8eb7eba55cdfd64c8d50181ea066526ff6485 Change-Id: I77cd27d3a4f207411a689b5be572b4406a03f16b Signed-off-by: Kayalvizhi Dhandapani Reviewed-on: http://review.coreboot.org/7026 Reviewed-by: Paul Menzel Reviewed-by: Marc Jones Tested-by: build bot (Jenkins) --- src/soc/intel/fsp_baytrail/Kconfig | 4 ++++ src/soc/intel/fsp_baytrail/cpu.c | 10 ++++++++-- 2 files changed, 12 insertions(+), 2 deletions(-) (limited to 'src/soc/intel/fsp_baytrail') diff --git a/src/soc/intel/fsp_baytrail/Kconfig b/src/soc/intel/fsp_baytrail/Kconfig index cb4757b..e9391c3 100644 --- a/src/soc/intel/fsp_baytrail/Kconfig +++ b/src/soc/intel/fsp_baytrail/Kconfig @@ -31,12 +31,16 @@ config CPU_SPECIFIC_OPTIONS select ARCH_ROMSTAGE_X86_32 select ARCH_RAMSTAGE_X86_32 select DYNAMIC_CBMEM + select HAVE_SMI_HANDLER select HAVE_HARD_RESET select MMCONF_SUPPORT select MMCONF_SUPPORT_DEFAULT select RELOCATABLE_MODULES select PARALLEL_MP select REG_SCRIPT + select SMM_MODULES + select SMM_TSEG + select BAYTRAIL_SMM select SMP select SPI_FLASH select SSE2 diff --git a/src/soc/intel/fsp_baytrail/cpu.c b/src/soc/intel/fsp_baytrail/cpu.c index f260880..6f1e9c4 100644 --- a/src/soc/intel/fsp_baytrail/cpu.c +++ b/src/soc/intel/fsp_baytrail/cpu.c @@ -148,14 +148,20 @@ static void adjust_apic_id_map(struct smm_loader_params *smm_params) runtime->apic_id_to_cpu[i] = mp_get_apic_id(i); } -static void asmlinkage -cpu_smm_do_relocation(void *arg, int cpu, const struct smm_runtime *runtime) +static void asmlinkage cpu_smm_do_relocation(void *arg) { #ifndef CONFIG_MAX_CPUS #error CONFIG_MAX_CPUS must be set. #endif msr_t smrr; em64t100_smm_state_save_area_t *smm_state; + const struct smm_module_params *p; + const struct smm_runtime *runtime; + int cpu; + + p = arg; + runtime = p->runtime; + cpu = p->cpu; if (cpu >= CONFIG_MAX_CPUS) { printk(BIOS_CRIT, -- cgit v1.1
