Issue #511 has been updated by Eugene Myers. In this instance, the STM is not active. The only thing coreboot does for the STM is setup some data structures and move the STM binary into the MSEG. The operating system has to start the STM. If coreboot is crashing when STM and SMMSTOREV2 are configured at the same time, this means that there is a collision in the TSEG layout. We need a coreboot trace to ferret this out. ---------------------------------------- Bug #511: [STM/PE][BUG][SMMSTORE] Coreboot doesn't boot if SMMSTOREv2 driver Kconfig option is enabled when using STM (STM/PE) https://ticket.coreboot.org/issues/511#change-1685 * Author: Elias Souza * Status: Needs Testing * Priority: High * Category: coreboot common code * Target version: 4.21 * Start date: 2023-10-09 * Affected hardware: is necessary testing in newest hardwares include Haswell and Kaby Lake, but idk if affect other platforms different than Sandybridge * Affected OS: All ---------------------------------------- For some reason the SMMSTOREv2 looks to break SMMSTORE support in STM/PE during boot. Coreboot: 4.21 HARDWARE: Gigabyte H61M-DS2 with Ivybridge processor Payload: EDK2 SMMSTORE: SMMSTOREv2 A example with other guy using https://www.reddit.com/r/coreboot/comments/10rakni/comment/k444jz1/?context=3 * According with the reddit user crazyfox-ua " The same for me on T440p & X230t (both with edk2) - just blank screen. Disabled STM brings both laptops back to life. CB logs says nothing strange IMO (last record is "[DEBUG] Jumping to boot code at <hex here>". Is necessary to test if others payloads is affected by this bug -- You have received this notification because you have either subscribed to it, or are involved in it.
