[coreboot - Feature #420] (New) Use standard format of TPM event log
by Krystian Hebel Aug. 7, 2024

Aug. 7, 2024

Issue #420 has been reported by Krystian Hebel. ---------------------------------------- Feature #420: Use standard format of TPM event log https://ticket.coreboot.org/issues/420 * Author: Krystian Hebel * Status: New * Priority: Normal * Target version: none * Start date: 2022-10-12 * Related links: [1] https://trustedcomputinggroup.org/wp-content/uploads/TCG_PCClientImplementa… [2] https://trustedcomputinggroup.org/wp-content/uploads/TCG_PCClient_PFP_r1p05… ---------------------------------------- Currently coreboot uses proprietary format for TPM event log. TCG has standardized log formats, differently for TPM1.2 (aka legacy or SHA1) [1] and TPM2.0 (aka crypto agile) [2], both of which can be parsed by Linux kernel and exposed in sysfs. I don't know of any tool outside of cbmem which can parse coreboot format; this includes payloads which may be interested in continuing chain of trust started by coreboot. Another incompatibility is caused by vboot's assignment of PCRs. Roles of PCRs are roughly specified by TCG in both of mentioned documents, they are more or less compatible with each other, but not with current coreboot code. These changes could break assumptions made by existing platforms, so they should be made as Kconfig options. This is a tracking issue to collect subtasks that need to be done in order to support standard event log formats. -- You have received this notification because you have either subscribed to it, or are involved in it.

[coreboot - Bug #121] T520: Hangs in OS
by Anastasios Koutian May 31, 2024

May 31, 2024

Issue #121 has been updated by Anastasios Koutian. I tried booting with kernel command line parameter idle=nomwait. There were no freezes for 1 week, 5 days and 16 hours, which was not possible previously. After this, I powered down and removed the parameter to see what happens. The system froze after 15 hours and 7 minutes. Intel PCM is showing no negative impact on idle power consumption with idle=nomwait. I recommend to people following this bug to try this out and confirm if it works for them. ---------------------------------------- Bug #121: T520: Hangs in OS https://ticket.coreboot.org/issues/121#change-1856 * Author: Firstname Lastname * Status: In Progress * Priority: Normal * Category: chipset configuration * Start date: 2017-06-09 * Affected hardware: SNB, IVY * Affected OS: - ---------------------------------------- I have been running coreboot since 2017.04.15 and have experienced hangs ever since then. It was suggested by folk on the IRC that I run memtest to check for incorrect raminit causing errors, however I have run memtest for 12 hours straight with no errors. Due to the ambiguous nature of the hangs (immediate freeze with no warning signs, audio gets stuck repeating the last 50ms or so of noise, not sure what this effect is called) I don't have much useful information other than the .config and dmesg. However one thing I can say with high confidence is that the hangs occur significantly more frequently in Linux (*buntu distros) than Windows 10. Within an hour of launching Linux a hang is likely, whereas Windows typically runs for many hours before a hang occurs. I considered this an insignificant anecdotal anomaly at first but over the course of the nearly 2 months I have been running coreboot it seems to be a solid trend. The hangs occur anywhere, typically during mere desktop usage or basic web browsing. Additionally there is another form of hang I experience where the screen goes black except for some sort of graphical corruption down the left side (http://i.imgur.com/4zWrlpX.jpg) whether this is related to the more common total freeze hangs I don't know but I figured I should include it nonetheless. These hangs only occur about 1:20 compared to the regular hangs. ---Files-------------------------------- config (20.7 KB) dmesg.txt (57.3 KB) cbmem-raminit.txt (62 KB) lspci.txt (29.6 KB) cpuinfo.txt (3.94 KB) defconfig (1023 Bytes) defconfig (699 Bytes) -- You have received this notification because you have either subscribed to it, or are involved in it.

[coreboot - Feature #461] (In Progress) Replacing Haswell mrc.bin blob with free software
by Angel Pons May 23, 2024

May 23, 2024

Issue #461 has been updated by Angel Pons. Category changed from board support to chipset configuration Status changed from New to In Progress Start date changed from 02/16/2023 to 04/01/2020 % Done changed from 0 to 30 Related links updated Affected hardware changed from T440p and other to All Haswell mainboards # Current state of the meme magic (Haswell NRI) ## Done - Native non-raminit stuff (already submitted): needed for 9-series boards with Broadwell MRC.bin e.g. https://review.coreboot.org/68188 - Bare minimum memory initialisation (just enough meme magic to be able to boot): patch train up until https://review.coreboot.org/64198 - S3 suspend/resume and fast boot support: https://review.coreboot.org/81897 - Sense amplifier offset training: https://review.coreboot.org/81948 ## Implemented internally in the giant bowl of spaghetti, but in need to clean up the code before publishing - 1D margin centering algorithms (used for various training steps) - Setting non-training command rate (to 1N or 2N, we currently remain at 3T) and LCT (Late Command Training) - 2D margin centering algorithms (used for various training steps) - Power training (optimisation meme magic to reduce power consumption) - TAT (Turnaround Training, a performance improvement) - The raminit console (a half-arsed thing that allows playing around with settings over UART/usbdebug) ## Not implemented or not working yet - Broadwell support (I once got a Broadwell ULT system to boot without MRC, but I had to commit unspeakable horrors to the already messy codebase) - Properly programming some registers about DIMM energy (doesn't seem to be required, but the logic to program these is horribly convoluted and I haven't felt like figuring out how it works) - Automatic overclocking support (will require redesigning how the MPLL handling works, because it currently stinks) # TL;DR - With what's currently submitted, choosing Haswell NRI in menuconfig **WILL NOT BOOT**. It says "NOT WORKING" in the prompt. - Current top of tree (what you should use if you want to try Haswell NRI) is https://review.coreboot.org/81948 - With the aforementioned changes from Gerrit, booting should work. S3 resume should also work, but please test in advance. - **BACK UP YOUR STUFF!** I will NOT be held responsible by any data losses arising from the use of the current state of Haswell NRI. - Because not all training steps are ready yet, performance and power consumption are not optimal. Fix is to finish upstreaming them. - Also, do NOT try to overclock the RAM under any circumstances. You will only make your system much more unstable for no reason. ---------------------------------------- Feature #461: Replacing Haswell mrc.bin blob with free software https://ticket.coreboot.org/issues/461#change-1854 * Author: akjuxr3 akjuxr3 * Status: In Progress * Priority: Normal * Assignee: Angel Pons * Category: chipset configuration * Target version: none * Start date: 2020-04-01 * Related links: https://review.coreboot.org/q/topic:haswell-nri * Affected hardware: All Haswell mainboards ---------------------------------------- Currently in case of the ability to run as less amount of closed source software as possible and still have Microcode updates the reduced Intel ME with disabled bit in IFD and the lga1155 or the mobile versions of those cpus are the only option for x86_64 out there. The next cpu generation (Haswell) inside for example T440p and W541 require the binary blob mrc.bin Are there any plans of replacing the Haswell mrc.bin with free software? Or have the x86_64 platform be given up when the goal is to run just free software and the people should move to aarch64 or risc-v? -- You have received this notification because you have either subscribed to it, or are involved in it.

[coreboot - Feature #540] (New) Support for Lenovo ThinkPad X250 - the competitor to the shortly added HP EliteBook 820 G2
by akjuxr3 akjuxr3 May 23, 2024

May 23, 2024

Issue #540 has been reported by akjuxr3 akjuxr3. ---------------------------------------- Feature #540: Support for Lenovo ThinkPad X250 - the competitor to the shortly added HP EliteBook 820 G2 https://ticket.coreboot.org/issues/540 * Author: akjuxr3 akjuxr3 * Status: New * Priority: Normal * Category: board support * Target version: none * Start date: 2024-05-22 * Affected hardware: Lenovo Thinkpad X250 ---------------------------------------- Coreboot now have support for the HP EliteBook 820 G2. This is great, but sadly the keyboard is for a person using Thinkpad keyboards forever not usable. The Thinkpad X250 is the competitor to the HP EliteBook 820 G2. https://www.notebookcheck.net/Face-Off-HP-EliteBook-820-G2-vs-Lenovo-ThinkP… The X250 also have a Full-HD IPS screen. This would also fix the problems many people have with the X230 and spend much time and effort to get a Full-HD IPS screen running in the X230. Nico Huber have(had?) such a X250: https://review.coreboot.org/c/coreboot/+/23820/7#message-04cf9f804c1292f457… Other coreboot developer also seem to have a X250: https://review.coreboot.org/c/coreboot/+/51179 Have someone taken a deeper look into the Thinkpad X250? Is there something special why suddenly the HP EliteBook 820 G2 got supported instead of a typical Thinkpad like it was the case for years at coreboot? -- You have received this notification because you have either subscribed to it, or are involved in it.
