regarding edk2 payload to boot to uefi aware OS
by ritul guru 06 Feb '23

06 Feb '23

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 06 Feb '23

06 Feb '23

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].

Status of maintained boards and policies?
by Denis 'GNUtoo' Carikli 03 Feb '23

03 Feb '23

Hi, The MAINTAINERS file has the following: > PC ENGINES ALL MAINBOARDS > M: Piotr Król <piotr.krol(a)3mdeb.com> > M: Michał Żygowski <michal.zygowski(a)3mdeb.com> > S: Supported > F: src/mainboard/pcengines/ But the commit f9decbb0c720662d8e71fe221aef55b7ecf76196 ("mb/*/*: Remove AMD family14 boards") actually removed the apu1 (src/mainboard/pcengines/). Is there some policy somewhere that describes what kind of support to expect from maintained boards? Is there also a policy that explains when boards are removed? Or what to do to prevent boards from being removed? For instance u-boot warns when building that a boards needs to be adjusted to the newer driver model. So just by building u-boot you know in advance what needs to be fixed and for when. I've looked in the Coreboot documentation but I didn't find any information about that. Also is there some public information on how much work it is to avoid a board being removed? Does it require to dedicate someone full time on it? Or does it usually requires less time? Also how changes that break other people's code are decided? Can anyone submit these changes and get them accepted with very few people agreeing to them? Or is there another procedure for these special changes? Denis.

Strange power button behavior
by Christopher Davis 01 Feb '23

01 Feb '23

I’m seeing problematic power button behavior on my ASUS C302 (Intel m3-6Y30 Skylake) Flip Chromebooks. With the lid closed the power button will not power on the C302 for a repeatable one hour and 20 seconds after shutdown, which is good, but after that it will. This is a problem because the power button can easily get bumped while the C302 is being transported. When this happens on my ChromeOS C302 the EC powers on the AP and coreboot executes, which in turn boots ChromeOS which shuts down immediately, mitigating the problem. When this happens on my Fedora 35 C302 the EC powers on the AP and coreboot (MrChromebox coreboot_tiano-cave-mrchromebox_20220718.rom UEFI) executes, which in turn boots Fedora 35 which then waits indefinitely for a LUKS passphrase to be entered, eventually resulting in a fully discharged battery. I would like to fix this and need help/advice. I think it’s an EC problem, not a coreboot problem, but I’m not sure. The C source file ec/common/power_button.c contains code in raw_power_button_pressed() that ignores the power button if the laptop lid is closed. That code has changed over time, becoming conditionally compiled depending on CONFIG_POWER_BUTTON_IGNORE_LID, and I don’t know which version of the EC code is in these C302s, but the fact that the power button is ignored with the lid closed for the first one hour and 20 seconds suggests that this code is present in these EC instances. I’m stumped by the change in power button behavior after one hour and 20 seconds. This is repeatable on four C302 laptops. At first I thought this might be a charge leakage problem in hardware lid switch circuitry or something like that, but it’s the same on all four C302 laptops, and is consistently repeatable, so I think that pretty much rules out hardware. That leaves softwwhatare as the cause. Maybe an overflow in a timer? A 32 bit unsigned integer overflow in a microsecond timer occurs in approximately one hour 12 minutes, not one hour 20 seconds, so that’s not it. What could be causing this, and how can it be fixed? I’ve thought about adding code to a custom version of coreboot to request the EC to power down the AP if coreboot is booted while the laptop lid is closed, but I’m not sure this is the best approach. Does coreboot have knowledge of the laptop lid state? I’ve also thought about adding code to a custom linux kernel to shut down during boot if the laptop lid is closed, but by the time the kernel has knowledge of the laptop lid state the boot is already well advanced – better to power down much earlier, in either coreboot or preferably the EC. I would welcome any comments or suggestions for solving this problem. Thank you in advance. -Dindoo

[coreboot - Bug #451] (New) Fix POST code handling
by Felix Singer 30 Jan '23

30 Jan '23

Issue #451 has been reported by Felix Singer. ---------------------------------------- Bug #451: Fix POST code handling https://ticket.coreboot.org/issues/451 * Author: Felix Singer * Status: New * Priority: Normal * Target version: none * Start date: 2023-01-29 ---------------------------------------- coreboot supports writing POST codes to I/O port 80. There are various Kconfigs that deal with POST codes, which don’t have effect on most platforms. The code to send POST codes is scattered in C and Assembly, some use functions, some use macros and others simply use the `outb` instruction. The POST codes are duplicated between stages and aren’t documented properly. ## Tasks * Guard Kconfigs with a depends on to only show on supported platforms * Remove duplicated Kconfigs * Replace `outb(0x80, ...)` with calls to `post_code(...)` * Update Documentation/POSTCODES * Use defines from console/post_codes.h where possible * Drop duplicated POST codes * Make use of all possible 255 values ## Requirements * Knowledge in the coreboot build system and the concept of stages * Other knowledge: Little experience with C and x86 Assembly * Hardware requirements: Nothing special ## Mentors * Patrick Rudolph patrick.rudolph(a)9elements.com * Christian Walter christian.walter(a)9elements.com -- You have received this notification because you have either subscribed to it, or are involved in it.
