From ab1605e91bd8a04f21f3d3cd81f63eb390ea6b9f Mon Sep 17 00:00:00 2001 From: Anil Kumar Date: Thu, 14 Sep 2023 14:48:21 -0700 Subject: soc/intel/meteorlake: Generate new TME key on each warm boot relanding original commit 5013c60a871af8fbce8c38a1c342c454e5b8452f ("soc/intel/meteorlake: Generate new TME key on each warm boot") which was previously reverted by commit 19e66b7c951ce71a1b9bc20158af56e559f8a58f (Revert "soc/intel/meteorlake: Generate new TME key on each warm boot") due to consecutive reboot post warm reset issue. The consecutive reboot post warm reboot issue has been fixed with commit ba7a9eefcf4e571bc73d4be1141f676fc5547057 ("soc/intel/common: Fix invalid MADT entries creation"), hence, reattempting to land the original TME key related patch. BUG=299294328 TEST=Boot up the system, generate kernel crash using following commands: $ echo 1 > /proc/sys/kernel/sysrq $ echo "c" > /proc/sysrq-trigger System performs warm boot automatically. Once it is booted, execute following commands in linux console of the DUT and confirm ramoops can be read. $ cat /sys/fs/pstore/console-ramoops-0 Signed-off-by: Anil Kumar Change-Id: I5d45d265ccef1a7d37669ea22a74b52e2f3ae20d Reviewed-on: https://review.coreboot.org/c/coreboot/+/77902 Tested-by: build bot (Jenkins) Reviewed-by: Pratikkumar V Prajapati Reviewed-by: Kapil Porwal Reviewed-by: Subrata Banik --- src/soc/intel/meteorlake/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/src/soc/intel/meteorlake/Kconfig b/src/soc/intel/meteorlake/Kconfig index 667c20227f..c4acba850d 100644 --- a/src/soc/intel/meteorlake/Kconfig +++ b/src/soc/intel/meteorlake/Kconfig @@ -89,6 +89,7 @@ config SOC_INTEL_METEORLAKE select SOC_INTEL_MEM_MAPPED_PM_CONFIGURATION select SSE2 select SUPPORT_CPU_UCODE_IN_CBFS + select TME_KEY_REGENERATION_ON_WARM_BOOT select TSC_MONOTONIC_TIMER select UDELAY_TSC select UDK_202302_BINDING -- cgit v1.2.3
