From b4d5bad9422b6bcfe7baed9080484d4fdba63310 Mon Sep 17 00:00:00 2001 From: Martin Kepplinger Date: Thu, 23 May 2019 16:00:29 +0200 Subject: [PATCH] config: coreboot-x230: add force=1 to tpm_tis Linux driver Add tpm_tis.force=1: "Force device probe rather than using ACPI entry". This prevents Linux from "hanging" for about 30 seconds after "switched to clocksource tsc" when loading this driver. TPM measurements seem to work, but we should look for the change in coreboot that causes this problem. --- config/coreboot-x230.config | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/config/coreboot-x230.config b/config/coreboot-x230.config index 25e3f2f41..6765772ed 100644 --- a/config/coreboot-x230.config +++ b/config/coreboot-x230.config @@ -17,6 +17,6 @@ CONFIG_CONSOLE_CBMEM_BUFFER_SIZE=0x80000 CONFIG_DEFAULT_CONSOLE_LOGLEVEL_5=y CONFIG_PAYLOAD_LINUX=y CONFIG_PAYLOAD_FILE="../../build/x230/bzImage" -CONFIG_LINUX_COMMAND_LINE="intel_iommu=igfx_off quiet" +CONFIG_LINUX_COMMAND_LINE="intel_iommu=igfx_off quiet tpm_tis.force=1" CONFIG_LINUX_INITRD="../../build/x230/initrd.cpio.xz" CONFIG_DEBUG_SMM_RELOCATION=y
