I missed the 24.02 boat on a patch.
by Keith Hui 04 Mar '24

04 Mar '24

Hi all, I missed the memo about the 24.02 release where I should have asked for this patch to be reviewed: mb/asus/p8x7x-series: Revert to native max_mem_clock_mhz of 800 https://review.coreboot.org/c/coreboot/+/79726 I'm trying to get a setting back to where it was where it turns out it didn't really break my board. I just put a tag there trying to make sure it gets into 24.05, but can it get a review whether it's worth a point release? Thanks and sorry for the trouble. Keith

coreboot versions 24.02 and 24.02.01 have been released
by coreboot org 03 Mar '24

03 Mar '24

The announcement on the blog is here: https://blogs.coreboot.org/blog/2024/03/01/coreboot-24-02-and-24-02-1-relea… coreboot 24.02 release ======================================================================== The coreboot project is happy to announce our release for February 2024. Over the past three months, our contributors have focused on refining the coreboot codebase, generally prioritizing cleanup and quality enhancements. We extend our gratitude to all the contributors who have dedicated their time and expertise. Thank you for your invaluable contributions to this vital phase of maintenance and optimization. The next release is scheduled for mid-May. ### Release number format update The previous release was the last to use the incrementing 4.xx release name scheme. For this and future releases, coreboot has switched to a Year.Month.Sub-version naming scheme. As such, the next release, scheduled for May of 2024 will be numbered 24.05, with the sub-version of 00 implied. If we need to do a fix or incremental release, we'll append the values .01, .02 and so on to the initial release value. ### The master branch is being deleted The coreboot project changed from master to main roughly 6 months ago, and has been keeping the two branches in sync since then to ease the transition. As of this release, we are getting rid of the master branch completely. Please make sure any scripts you're using that reference the 'master' branch have been switched to 'main'. Release 24.02.1 --------------- ### lib/rtc: Fix off-by-one error in February day count in leap year The month argument passed to rtc\_month\_days is 0-based, not 1-based. This results in the RTC being reverted to the build date constantly on 29th February 2024. Significant or interesting changes ---------------------------------- ### acpi: Add Arm IO Remapping Table structures Input Output Remapping Table (IORT) represents the IO topology of an Arm based system. Document number: ARM DEN 0049E.e, Sep 2022 ### acpi: Add PPTT support This patch adds code to generate Processor Properties Topology Tables (PPTT) compliant to the ACPI 6.4 specification. - The 'acpi_get_pptt_topology' hook is mandatory once ACPI_PPTT is selected. Its purpose is to return a pointer to a topology tree, which describes the relationship between CPUs and caches. The hook can be provided by, for example, mainboard code. Background: We are currently working on mainboard code for qemu-sbsa and Neoverse N2. Both require a valid PPTT table. Patch was tested against the qemu-sbsa board. ### acpi: Add support for WDAT table This commit lays the groundwork for implementing the ACPI WDAT (Watchdog Action Table) table specification. The WDAT is a special ACPI table introduced by Microsoft that describes the watchdog for the OS. Platforms that need to implement the WDAT table must describe the hardware watchdog management operations as described in the specification. See â€œLinks to ACPI-Related Documentsâ€ (http://uefi.org/acpi) under the heading â€œWatchdog Action Tableâ€ . ### lib/jpeg: Replace decoder with Wuffs' implementation To quote its repo[0]: Wuffs is a memory-safe programming language (and a standard library written in that language) for Wrangling Untrusted File Formats Safely. Wrangling includes parsing, decoding and encoding. It compiles its library, written in its own language, to a C/C++ source file that can then be used independently without needing support for the language. That library is now imported to src/vendorcode/wuffs/. This change modifies our linters to ignore that directory because it's supposed to contain the wuffs compiler's result verbatim. Nigel Tao provided an initial wrapper around wuffs' jpeg decoder that implements our JPEG API. I further changed it a bit regarding data placement, dropped stuff from our API that wasn't ever used, or isn't used anymore, and generally made it fit coreboot a bit better. Features are Nigel's, bugs are mine. This commit also adapts our jpeg fuzz test to work with the modified API. After limiting it to deal only with approximately screen sized inputs, it fuzzed for 25 hours CPU time without a single hang or crash. This is a notable improvement over running the test with our old decoder which crashes within a minute. Finally, I tried the new parser with a pretty-much-random JPEG file I got from the internet, and it just showed it (once the resolution matched), which is also a notable improvement over the old decoder which is very particular about the subset of JPEG it supports. In terms of code size, a QEmu build's ramstage increases from 128060 bytes decompressed (64121 bytes after LZMA) to 172304 bytes decompressed (82734 bytes after LZMA).

[coreboot - Bug #121] T520: Hangs in OS

I eventually had to reboot due to a necessary update, so it might be a premature conclusion. I will keep the system running for as long as I can to confirm. I haven't gotten around to comparing with MSRs on stock firmware yet, but will once I have spare time. ---------------------------------------- Bug #121: T520: Hangs in OS https://ticket.coreboot.org/issues/121#change-1771 * 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.

Gitiles, the gerrit file viewer has been disabled
by Martin Roth 02 Mar '24

02 Mar '24

Hi Everyone, We've been having issues with the gitiles file browser crashing gerrit, so we've disabled it temporarily. The issue seems to have been caused by a crawler trying to get data from gitiles. This was generating a significant amount of traffic and causing gerrit to slow down and eventually crash. Gitiles in general seems to be a source of issues, but the excessive traffic definitely made it worse. We're going to do what we can to prevent this from happening again, but we're not sure how long that's going to take. If you have any questions, please respond here. Martin

Critical bug in RTC code for a leap year
by Michał Żygowski 29 Feb '24

29 Feb '24

Hi folks, Another leap year, another problem with RTC in firmwares :) This time, unfortunately, this kind of bugs hit coreboot. I have issued a patch that fixes off-by-one error in the days count in month for a leap year: https://review.coreboot.org/c/coreboot/+/80790 It is quite critical, because depending on build date, it may revert to some very old date, like January 2023 or even older (depending on how long you run on current firmware). That said, the consequences are enormous: from false-negative expired certificates, to problems with filesystems, etc. It is worth considering an emergency coreboot release, is it not? Best regards, -- Michał Żygowski Firmware Engineer GPG: 6B5BA214D21FCEB2 https://3mdeb.com | @3mdeb_com
