SMMSTORE_V2 support for camelback mountain CRB
by Moorthi M.s Feb. 11, 2023

Feb. 11, 2023

Hi, I am developing coreboot along with uefipayload for camelback mountain crb. Board booted and working but not able to store the NVRAM BIOS configuration details. I am using coreboot 4.11 and found that the SMMSTORE_V2 is not implemented in that particular version. I tried to add SMMSTORE_V2 feature, but failed. whether the broadwell DE supports SMMSTORE_V2? Is there any other way avilable to save the BIOS boot configuration? Regards, Moorthi S

[coreboot - Bug #457] (New) Haswell (t440p): CAR memory region should not conflict with CBFS_SIZE > 8mb
by Thierry Laurion Feb. 8, 2023

Feb. 8, 2023

Issue #457 has been reported by Thierry Laurion. ---------------------------------------- Bug #457: Haswell (t440p): CAR memory region should not conflict with CBFS_SIZE > 8mb https://ticket.coreboot.org/issues/457 * Author: Thierry Laurion * Status: New * Priority: Normal * Target version: none * Start date: 2023-02-08 * Affected versions: 4.19, master ---------------------------------------- When neutering ME to pass freed space to IFD BIOS region (and having CBFS_SIZE match maximized IFD region), booting of the platform was reported to take an additional 20 seconds. A quick review at FOSDEM with a coreboot dev inspecting current Haswell code suggested that fixing DCACHE_RAM_BASE might fix the issue under src/northbridge/intel/haswell/Kconfig: 0xff7c0000 -> 0xfe7c0000 ----- Unfortunately, I have no access to a t440p to test the fix. It was also suggested that mrc.bin might need to be patched as well. But 4.19 is bringing native raminit, so that might not be an issue? Attached is the suggested change to be tested. ---Files-------------------------------- haswell_car_20230205233221.patch (369 Bytes) -- You have received this notification because you have either subscribed to it, or are involved in it.

[coreboot - Bug #449] ThinkPad T440p fail to start, continous beeping & LED blinking
by Angel Pons Feb. 7, 2023

Feb. 7, 2023

Issue #449 has been updated by Angel Pons. https://review.coreboot.org/72806 fixes the UBSAN errors, please review. Note that UBSAN-enabled coreboot still dies later on: ``` Loading module at 0x00030000 with entry 0x00030000. filesize: 0x178 memsize: 0x178 Processing 16 relocs. Offset value of 0x00030000 unaligned access src/lib/rmodule.c:152:27 ubsan: unrecoverable error. ``` So, any users that desire to have a bootable system should keep UBSAN disabled when building coreboot. ---------------------------------------- Bug #449: ThinkPad T440p fail to start, continous beeping & LED blinking https://ticket.coreboot.org/issues/449#change-1394 * Author: Crazy Fox * Status: In Progress * Priority: Normal * Assignee: Angel Pons * Category: board support * Target version: 4.18 * Start date: 2023-01-14 * Affected versions: 4.19 * Related links: The USBAN error is: ``` [ERROR] shift out of bounds src/northbridge/intel/haswell/pcie.c:85:22 [EMERG] ubsan: unrecoverable error. ``` * Affected hardware: haswell ---------------------------------------- Hi, Team Being corebooted before and works fine on 4.17. After flashing 4.18 my t440p wont startup (black screen, constant beeping & LED blinking). I've tried and retried different nconfigs but result is the same. I know that it is lack of information, but I need to recover the laptop first to grab some logs from it. Log from FT232H's debug is attached, the rest of info (defconfig, flashrom command etc. will upload soon) ---Files-------------------------------- coreboot_t440p_emerg.log (7.85 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.

Cr50 is not the only Google security chip
by Vadim Bendebury Feb. 6, 2023

Feb. 6, 2023

Hello fellow Coreboot enthusiasts, I am not sure if I am the only one annoyed/confused when I see coreboot messages like "Error reading from Cr50" or "Did not recognize Cr50 version format", etc. while the device in fact is using a different GSC (Google Security Chip). Before I go for it - would there be objections to changing the source code (including path and file name changes) from Cr50 to GSC where appropiate? TIA, -vb

regarding edk2 payload to boot to uefi aware OS
by ritul guru Feb. 6, 2023

Feb. 6, 2023

Hi, In earlier coreboot, there was a tianocore payload which has 1. CorebootPayload 2. UEFIPayload I used to boot with CorebootPayload to UEFI aware OS. I see, now it is edk2 payload, is CorebootPayload deprecated? and building alone uefipayload.fd is enough to boot to UEFI aware OS with coreboot BIOS? *Thanks & RegardsRitul Guru+91-9916513186*

Recent board removal for deprecated features LEGACY_SMP_INIT and RESOURCE_ALLOCATOR_V3
by Paul Menzel Feb. 5, 2023

Feb. 5, 2023

Dear coreboot folks, Two days ago, on November 7th, the change-sets of the topic *drop_LEGACY_SMP_INIT* [1] were submitted after being created on November 2nd [2]. The removal was announced on the list some time ago and was documented in the release notes. 1. RESOURCE_ALLOCATOR_V3 in the 4.16 release notes [3] 2. LEGACY_SMP_INIT in the 4.16, 4.17, and 4.18 release notes [4] (I think that planned deprecations should to be listed in each release note.) Despite the missing RESOURCE_ALLOCATOR_V3 deprecation announcement in 4.17 and 4.18, everything was done formally correct, nevertheless I would have wished, more time would have been given and the actions would have been announced once more on the mailing list. My understanding was always, that code removal will be handled more leniently, if the required changes are being worked on. This was the case here for parallel SMP init [5] and resource allocator v4 [6]. Some change-sets even had a +1 or +2. The request for testing was also fulfilled by the users. Some of the change-sets were even authored by “non-AGESA“ folks, which was awesome to see. Letting this effort go to waste without documenting somewhere, what needed to be done to finish these change-sets makes me sad. 3mdeb also invested resources into implementing some of the features. The last thing I noticed, that at least for the PC Engines board removal, the approval of the maintainers listed in `MAINTAINERS` was not given, and should have been waited for. The +2 itself were also by developers normally not (very) active with AMD AGESA Open Source boards. The points above are just my observations, and, hopefully, things can improve in the future to avoid bad feelings. I am thankful to everyone working on coreboot, and I also understand the frustration of having to maintain several code paths. Although I own and run two of the removed boards, I am fine to move to the branch *4.18_branch* although I am not happy about it, as branches also increase maintenance burden. The main reason for writing this message is to ask, if entities (read 3mdeb) have big interest in getting part of the boards back into the master branch, so that the already made investments are not in vain, and nobody is alienated from working upstream. If that is a goal, this effort should be coordinated as reverting commits is going to become harder and harder. mb/aopen/dxplplusu (Intel) is already worked on to be put back into the master branch [7]. Kind regards, Paul [1]: https://review.coreboot.org/q/topic:drop_LEGACY_SMP_INIT [2]: https://review.coreboot.org/c/coreboot/+/69111/2 [3]: https://review.coreboot.org/plugins/gitiles/coreboot/+/refs/tags/4.18/Docum… [4]: https://review.coreboot.org/plugins/gitiles/coreboot/+/refs/tags/4.18/Docum… [5]: https://review.coreboot.org/c/coreboot/+/64892 "cpu/amd/family15: Use parallel_mp init" [6]: https://review.coreboot.org/c/coreboot/+/53990 "nb/amd/agesa/family15tn: Enable RESOURCE_ALLOCATOR_V4" [7]: https://review.coreboot.org/c/coreboot/+/69339 "Revert "mb/aopen/dxplplusu: Remove board""

This can cause a race condition on certain OS's, especially if HDA enumeration runs before the GPU driver initializes the card in the OS (or happens if the GPU driver doesn't run at all, which can happen on all OS's with boot args or uninstalling the GPU driver) -- You have received this notification because you have either subscribed to it, or are involved in it.
