Alas, the flash console log ends before ramstage. It's often not fully working, but was worth a shot.
Maybe a cbmem log with RESOURCE_ALLOCATION_TOP_DOWN disabled would already provide some insight. But it's really a bit like shooting in the dark.
I am assuming that the cbmem log is the same as the log generated by CONFIG_CONSOLE_SPI_FLASH - if this is not the case, I will be more than happy to provide the appropriate log where possible. Unfortunately, enabling CONFIG_CONSOLE_SPI_FLASH also causes the build without CONFIG_RESOURCE_ALLOCATION_TOP_DOWN to fail to boot. I will look into determining whether it is possible to output the relevant log to an available port on the hardware, rather than storing the log on SPI flash.
---------------------------------------- Bug #499: coreboot will not boot edk2 on Lenovo T440p with CONFIG_RESOURCE_ALLOCATION_TOP_DOWN enabled, cannot disable this setting during build https://ticket.coreboot.org/issues/499#change-1570
* Author: Oberon 4071 * Status: New * Priority: Normal * Assignee: Nico Huber * Start date: 2023-06-29 * Affected versions: 4.21 * Needs backport to: none * Affected hardware: lenovo/t440p ---------------------------------------- coreboot revision in git: feb27dcbf3fc685b070c950a16e8adec958bc1ce coreboot revision (git describe --tags): 4.20-520-gfeb27dcbf3 Tested payloads: edk2 from MrChromebox revision uefipayload_202304 and uefipayload_202306
coreboot will not boot my Lenovo ThinkPad T440p with CONFIG_RESOURCE_ALLOCATION_TOP_DOWN enabled, when using the edk2 payload (MrChromebox version, either uefipayload_202304 or uefipayload_202306). The display sometimes turns on, indicating that some of the hardware initialization was successful, but the payload will not start.
I tried to disable CONFIG_RESOURCE_ALLOCATION_TOP_DOWN in .config, but the build process insists on leaving this config enabled. This seems to be caused by the RESOURCE_ALLOCATION_TOP_DOWN setting changed to "def_bool y" in src/device/Kconfig in commit 5226301765ded70e0ef640e5252bbaca8cd14451 (allocator_v4: Treat above 4G resources more natively). The make target for building coreboot seems to automatically rerun olddefconfig, causing this setting to always remain enabled no matter what was previously saved in the .config file.
Modifying src/device/Kconfig to change RESOURCE_ALLOCATION_TOP_DOWN to "def_bool n" appears to fix the problem on my machine.
I have attached my .config file (with CONFIG_RESOURCE_ALLOCATION_TOP_DOWN enabled to reproduce the problem).
