CBFS CSE version Mismatch
by Sameeruddin Shaik 23 Aug '22

23 Aug '22

hi , I built a coreboot image for ADL RVP, In that image cse lite cbfs version is not matching with the cse lite RO and RW version. As a result, target is updating the CBFS cse lite and rebooting again and again. Any Thoughts on how to fix this?. Below is the log ------------------------------ romstage starting (log level: 8)...

Issue tracker version update / disabling of login methods
by Felix Singer 18 Aug '22

18 Aug '22

Hi all, the Redmine developers released version 5.0 some months ago and updating to this version will have some effects on us. So, I would like to open a thread to discuss these issues with you and how we deal with that situation. Currently, we are on the 4.2 branch and it still gets security and bug fixes, but I can't tell at which point they will stop supporting it. We enabled the login over OpenID, which is implemented natively and not integrated over a plugin. With version 5.0, support for that was removed. I assume this is due to that the implementation is based on an older OpenID standard and there are not many users of it anymore (TM). The newer standard seems to be called "OpenID Connect", but it's not supported by Redmine. Also, we are using a plugin which allows the login over a Google account. The compatibility of that plugin breaks with version 5.0. The problem is that we have users for both and with version 5.0 they won't be able to use these methods anymore. However, I have an idea for a solution. I took a look at the Redmine database and I played around with the Google login method. My tests showed that it creates a normal user account, as it is done with the registration, just with the little difference that no password is set disabling the login over password. These accounts also have an user name and an email address. As soon as I set a password, I was able to login using the user name. So, my idea is that we just go with these changes and affected users use the functionality to reset their password, which means they will have a "normal" user account then. In preparation to that version update, we should disable these login methods so that no new users will make use of them. Other ideas? What's your opinion? // Felix

Intel sandybridge northbridge with ibexpeak southbridge?
by Hal Martin 18 Aug '22

18 Aug '22

Hello, I have a platform (Advantech NAMB-3250MB, used in some Riverbed appliances) which uses Sandy/Ivy Bridge CPUs, but has a DH89xxCC southbridge which according to ifdtool is Ibex Peak. [3] The ME firmware version from the vendor firmware is 6.0.50.1244 which also corresponds to Ibex Peak (Series 5) and not Cougar Point (Series 6). [1] I did not know it was possible to pair a Series 5 chipset with Sandy/Ivy Bridge, since the DH89xxCC only supports DMI 1 (intel-communications-chipset-89xx-series-datasheet.pdf page 5) and Sandy/Ivy Bridge support DMI 2.0 [2] It would appear that using northbridge/intel/sandybridge with southbridge/intel/ibexpeak in coreboot is not supported: /opt/coreboot/util/crossgcc/xgcc/bin/i386-elf-ld.bfd: build/romstage/northbridge/intel/sandybridge/early_dmi.o: in function `early_init_dmi': /opt/coreboot/src/northbridge/intel/sandybridge/early_dmi.c:175: undefined reference to `early_pch_init_native_dmi_pre' /opt/coreboot/util/crossgcc/xgcc/bin/i386-elf-ld.bfd: /opt/coreboot/src/northbridge/intel/sandybridge/early_dmi.c:215: undefined reference to `early_pch_init_native_dmi_post' /opt/coreboot/util/crossgcc/xgcc/bin/i386-elf-ld.bfd: build/romstage/northbridge/intel/sandybridge/raminit.o: in function `init_dram_ddr3': /opt/coreboot/src/northbridge/intel/sandybridge/raminit.c:322: undefined reference to `early_pch_init_native' src/arch/x86/Makefile.inc:185: recipe for target 'build/cbfs/fallback/romstage.debug' failed make: *** [build/cbfs/fallback/romstage.debug] Error 1 There is no early_pch_init_native_* in src/southbridge/intel/ibexpeak Is it safe to assume that IronLake northbridge is not applicable to Sandy/Ivy Bridge CPUs? In which case, I guess the only way this platform could ever be supported is if the missing early_pch_init_native_* functions are implemented for IbexPeak?

RFC: Deprecating VBOOT_VBNV_CMOS
by Yu-Ping Wu 15 Aug '22

15 Aug '22

Hi, There's an ongoing effort to expand vboot nvdata (nvstorage) from 16 to 64 bytes [issue <https://issuetracker.google.com/issues/172342278>]. To reduce unnecessary complexity of our firmware code accessing nvdata, we'd like to drop 16-byte nvdata support from the firmware codebase (crossystem still needs to support both though). One obstacle is the CMOS nvdata backend (VBOOT_VBNV_CMOS). We're not sure if there would be enough CMOS space for all boards using that. In addition, because CMOS loses state when the battery is removed, newer boards usually select VBOOT_VBNV_CMOS_BACKUP_TO_FLASH to backup nvdata to flash. Considering that, this seems like a good opportunity to migrate CMOS to flash nvdata [issue <https://issuetracker.google.com/issues/235293589>]. One problem we faced is that many old platforms such as broadwell don't support writing to the flash in early stages (BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES). Therefore it looks like we'd need to drop vboot support on them (for example CB:65782 <https://review.coreboot.org/c/coreboot/+/65782>). An alternative would be to keep the CMOS backend around as "deprecated" and not allow 64-byte nvdata for it, but that would at best be a transitory solution for a couple of years, not forever. If there's any concern, please let me know. We have firmware branches for ChromeOS devices, so modifying ToT code wouldn't affect old devices in any way. However, I'm not sure how non-ChromeOS boards (such as mainboard/lenovo/haswell) would be affected by this. Please cc more people if needed. -- Yu-Ping Wu | Software Engineer | yupingso(a)google.com | +886 937 057 080

Compatibility with legacy boards
by Benoît Dufour 13 Aug '22

13 Aug '22

Hello, I saw one of my old board is listed compatible on the CoreBoot wiki : https://www.coreboot.org/Board:asus/p5gc-mx but knowing the wiki is "being retired". I don't know if it is still supported by the latest version of CoreBoot. Then the Status (as of commit 5bb27b7815) chart has broken colors. So it is hard to me to tell if everything is working fine or not. Then my board is the P5GC-MX/1333 and not the P5GC-MX. I could attempt to flash the Coreboot BIOS to it, but I would want to know if it could bring me some advantages other than "it is free software". For example, the original manufacturer BIOS doesn't supports booting from USB, does CoreBoot supports it?

Heads up: Allocator changes
by Nico Huber 10 Aug '22

10 Aug '22

Hi coreboot fellows, after two years with the new resource allocator it's time again for some changes[1]. Much less invasive than last time, but again there will be changes in the pattern where resources are placed. So once more this may uncover bugs in case fixed resources are not reserved properly. Reasons for the changes are somewhat the same as always: we haven't finished the support for 64-bit resources. Currently one has to opt in for a placement above 4G with a resource flag, and even this has its limitations. For instance, reserved space for hot-pluggable de- vices can be placed above 4G with a Kconfig setting, but there's no rule what should happen with the resources of cold-plugged devices. In the worst case, allocation for those can fail. Another reason are approaching changes to support multiple PCI host bridges and multiple resource windows per domain. I digress... So everybody is invited to test the patch train. There is a new Kconfig option RESOURCE_ALLOCATION_TOP_DOWN. The default y should work fine, though in case of regressions it would be nice to have it tested with both settings. Cheers, Nico [1] https://review.coreboot.org/q/topic:allocator+status:open

APOLLOLAKE FSP can find FIT signature
by roman perepelitsin 10 Aug '22

10 Aug '22

Trying to run coreboot on apollo lake atom CPU. I'm stopped at romstage - on call FspMemoryInit I get this message (from debug FSP): FitHeader signature was invalid. As I understood - this mean that FSP can't validate FIT header in memory: "_FIT_ ". I have no ideas what going wrong. I'm doing all by guidlines and recomendations - but have this problem. Also, what mean this coreboot out: CBFS: Unmatched 'filename' at 'offset' ? Thanks! -- regards, Perepelitsin Roman
