QEMU x86 i440fx/piix4 build fails for >= 32MB ROMs - Assertion IS_HOST_SPACE_ADDRESS(host_space_address) failed

[coreboot - Bug #392] (New) Coreboot 4.16 & 4.17 - SeaBios Windows 10 BSOD "ACPI Error"
by Pawel Radomychelski 15 Jan '23

Issue #392 has been reported by Pawel Radomychelski. ---------------------------------------- Bug #392: Coreboot 4.16 & 4.17 - SeaBios Windows 10 BSOD "ACPI Error" https://ticket.coreboot.org/issues/392 * Author: Pawel Radomychelski * Status: New * Priority: High * Category: board support * Target version: 4.17 * Start date: 2022-06-18 * Affected versions: 4.16, 4.17, master * Affected hardware: Lenovo ThinkPad X230 Tablet * Affected OS: Windows 10 ---------------------------------------- Since CoreBoot 4.16 my Windows 10 cant boot from SeaBios, i get BSOD with "ACPI Error" very early. Don't know which commit exactly brakes ACPI, but i can say, that in my CoreBoot 4.15 Image from 11/09/2021 Windows 10 is booting just fine from SeaBIOS. Some time later under CoreBoot 4.16 i saw that windows is BSODing. Tried yesterday with CoreBoot 4.17 and its still broken. I think, since CB4.16 there is something broken in ACPI. As i read, the problem is, that ACPI reserves some memory area, which in Windows is reserved for the system. This [[https://ticket.coreboot.org/issues/327]] seems to be a similar problem, but the guy is using TianoCore instead of SeaBIOS. Changing the line OperationRegion (OPRG, SystemMemory, ASLS, 0x2000) to OperationRegion (OPRG, SystemMemory, ASLS, 0x1000) doesnt fix it for SeaBios, but fix it for TianoCore. ---Files-------------------------------- dmesg_cb415.txt (78.9 KB) dmesg_cb417.txt (79.9 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.

[coreboot - Bug #386] (New) ASUS P8Z77-V LX2 - Raminit issue at second boot with two 8GiB DIMMs - bootloop

Issue #386 has been reported by gzz5f gzz5f. ---------------------------------------- Bug #386: ASUS P8Z77-V LX2 - Raminit issue at second boot with two 8GiB DIMMs - bootloop https://ticket.coreboot.org/issues/386 * Author: gzz5f gzz5f * Status: New * Priority: High * Category: board support * Target version: master * Start date: 2022-06-05 * Affected versions: master * Needs backport to: none * Affected hardware: ASUS P8Z77-V LX2 * Affected OS: all ---------------------------------------- I build coreboot today for the ASUS P8Z77-V LX2 and used the latest coreboot master code. The 2 8GiB DIMMs are working fine at first boot. You can start computer, install from a live media the OS and so on. But at the second boot it failes boot forever and its bootooping. It does not make a change if i boot for a second until SeaBIOS output and then turn off the computer or use the computer for longer time. The second boot is always broken. Workaround 1: Remove one of the two 8GiB DIMMs. Then the computer also starts fine after a reboot. Workaround 2: Install two 4GiB DIMMs instead of two 8GiB DIMMs. Then the computer also starts fine after reboot. Workaround 3: At every boot boot for a second with one DIMM. Turn off the computer, insert the second DIMM and start it again. kmalkki told me to rebuid the image with DEBUG_RAM_SETUP=y I then build a second image, with DEBUG_RAM_SETUP=y. The logfile contains the first successfull boot (created with Workaround 3), the poweroff and the poweron with the bootloop. I have let it bootloop few times before turned off the PSU. ---Files-------------------------------- coreboot_logfie.txt (197 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.

[coreboot - Support #387] (New) Support Framework Laptop

Issue #387 has been reported by Jun Aruga. ---------------------------------------- Support #387: Support Framework Laptop https://ticket.coreboot.org/issues/387 * Author: Jun Aruga * Status: New * Priority: Normal * Category: board support * Target version: none * Start date: 2022-06-05 * Affected hardware: Framework Laptop ---------------------------------------- Dear coreboot developers, I am a user of Framework Laptop[1][2]. Thank you for working to make coreboot work on Framework Laptop! This ticket is to track the task, as I didn't see any other issue tickets about Framework Laptop here. According to the Framework founder's comment[3] below, Framework provided Framework Laptops to the coreboot community. > We've handed three systems that can boot unsigned bootloaders to folks in the coreboot community. Our plan in the near term is to help them create a shim loader that can be signed to run on any Framework Laptop, which then enables anyone to do further coreboot development. Then I saw Matthew's try to make the coreboot work on Framework Laptop,[4] but unfortunately it didn't work at that time.[5] How is the current status? What prevents coreboot from working on the Framework Laptop? How can we, people in the Framework community, help you? As a reference, there is a coreboot specific thread on the Framework community forum.[6] ## References * [1] https://frame.work/ * [2] Framework Computer - Wikipedia - https://en.wikipedia.org/wiki/Framework_Computer * [3] Framework Laptop Mainboard, Hacker News, April 20, 2022 - https://news.ycombinator.com/item?id=31097434 * [4] Matthew tries to port Coreboot to the Framework laptop - February 27, 2022 - https://www.youtube.com/watch?v=Jf_6xW-8tfQ * [5] Matthew Garrett on Twitter, February 27, 2022 - https://twitter.com/mjg59/status/1497788538212917250 * [6] Free the EC! and Coreboot Only - https://community.frame.work/t/free-the-ec-and-coreboot-only/791 -- You have received this notification because you have either subscribed to it, or are involved in it.

Cisco Meraki use coreboot in some MX products and will not provide the source code
by Hal Martin 22 Dec '22

22 Dec '22

Hello, Several Cisco Meraki products (MX84, MX250) are using the coreboot bootloader. Meraki are also distributing coreboot builds for these products via their update mechanism. In October 2021, I requested the corresponding coreboot source code for the MX84 from open-source(a)meraki.com. Another individual requested the coreboot source code for the MX250 around the same time. We own the devices in quesiton. To date, Meraki have not provided the source code or provided an explanation as to the delay in providing the source code. The last reply I received was in January, and they have not replied to any of my follow up requests. As coreboot is GPL licensed software, I wanted to inform the coreboot community that I believe Cisco Meraki are not acting in good faith and are, in my opinion, violating the GPL by not providing the coreboot source code upon request. Kind regards, Hal Martin

Invalid opcode exception(06) while loading network drivers in CamelBack Mountain CRB (Coreboot-4.11 + Uefipayload)
by Noyal Johnson 29 Aug '22

29 Aug '22

Hi, I am building the coreboot-4.11 with Uefipayload for Camelback Mountain FSP-based CRB. I am seperately compiling the Uefipayload in the edk2 tool (version : uefipayload_202107) downloaded from Mrchromebox in the github and merging as an ELF executable payload. The coreboot was succesfully loaded and OS was booted. In the UEFI shell, when I tried to use network, it was seen that network controller and stack drivers are not available in the payload. I have seperataly compiled the network stack drivers in the same edk2 tool and tried to load at runtime in the UEFI shell along with the network controller driver provided by Intel. At first, I loaded network controller driver and the device was detected as given below "Intel(R) I210 Gigabit Network Connection" Later, I tried loading the network stack drivers in the sequence given below 1, SnpDxe.efi 2, MnpDxe.efi 3, ArpDxe.efi While loading the "ArpDxe.efi", an exception has been occured given below, !!!! X64 Exception Type - 06 (#UD - Invalid Opcode) CPU Apic ID - 00000000 !!!! !!! Cant find image information !!! I tried loading Uefipayload in which network stack drivers are merged at compile time, still the result was same. But, when I tried loading the network stack drivers compiled in same edk2 tool and network controller driver in the actual BIOS present in CRB, all the network stack drivers was successfully loaded and ethernet was initilized. I am suspecting that network stack driver / controller driver is trying to execute a particular instruction which is not supported in coreboot. Whether any instruction sets I have to separately enable in coreboot. If no, what could be the reason for this exception. Regards, Noyal Johnson
