End user flash tool - Adding new working configurations and testing
by Łukasz Dmitrowski Aug. 18, 2015

Aug. 18, 2015

Hello, I am looking for people who want to help with testing automatic building of coreboot rom(and other features) with end user flash tool. To make automatic building possible for your machines first I need to prepare a configuration for particular hardware set(s). Until tomorrow I will provide a pdf with description of application features, building process and rest of details.For now best source of info about the app is here: http://blogs.coreboot.org/blog/author/dmitro/ If someone wants to help with testing (and also making a list of working configurations bigger) please contact me and send: * lspci -nn output * cat /sys/class/drm/card0-LVDS-1/edid | edid-decode * dmidecode –t 2 * short description of how you normally proceed with building image for your system (important or unusual steps), are additional option roms or other kinds of action needed? * if it needs factory VGABIOS, which one is working – extracted from memory or extracted from factory BIOS rom? please also attach needed file(s) * coreboot .config file with your configuration Thanks in advance for help! Regards, Lukasz Dmitrowski

[Mohon Peak] Memtest86+

Hello, I try to perform some memory test on the Mohon Peak CRB with memtest86+. I downloaded memtest86+ v5.01 and compile it. So far, so good. Following the thread: http://www.coreboot.org/pipermail/coreboot/2015-January/079143.html concerning this topic, I modified the given values, so that now: [root@localhost memtest86+-5.01]# readelf -e memtest1modified ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: EXEC (Executable file) Machine: Intel 80386 Version: 0x1 Entry point address: 0x10000 Start of program headers: 52 (bytes into file) Start of section headers: 151580 (bytes into file) Flags: 0x0 Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 1 Size of section headers: 40 (bytes) Number of section headers: 3 Section header string table index: 2 Section Headers: [Nr] Name Type Addr Off Size ES Flg Lk Inf Al [ 0] NULL 00000000 000000 000000 00 0 0 0 [ 1] .data PROGBITS 00010000 001000 024008 00 WA 0 0 1 [ 2] .shstrtab STRTAB 00000000 025008 000011 00 0 0 1 Key to Flags: W (write), A (alloc), X (execute), M (merge), S (strings) I (info), L (link order), G (group), x (unknown) O (extra OS processing required) o (OS specific), p (processor specific) Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x010000 0x00010000 0x00010000 0x24008 0x24008 RW 0x200000 Section to Segment mapping: Segment Sections... 00 .shstrtab [root@localhost memtest86+-5.01]# What gives the same scheme as in the previously mentionned thread.

I will include a few other emails in this one. The first I sent to Ron Minnich only when I meant to 'reply all' to the mailing list, and the rest are excerpted from a conversation on the Xen-devel mailing list. #%&#%&#&% Sent just to Ron, reply to quoted text above #%&#%&#%& If you saw my comments about VT-x in my conversation with John Lewis, VT-x has been working correctly while running Xen via the Qubes distribution. VT-x was being activated, I assume, by Xen, since you say Coreboot modifies none of these bits. I tried quite a few search engine queries to try to find the MSR for VT-d (assuming it exists) without any luck. So, I found that on mail-archive.com you can search through the archive history of this mailing list (which, btw is a great future the on-site archives lack, and to whomever it would concern maybe you should consider adding this feature or otherwise linking to mail-archive.com) It seems IOMMU support for Intel was first added by this commit: http://review.coreboot.org/#/c/1654/. I decided to see if any of this code is still present in firmware-samus-6300.b, and it turns out it can in fact still be found at /src/arch/x86/boot/acpi.c. There is little if any modification to it. I don't really have any clue what the code itself is doing, so beyond this I'm lost. Noah #%&#%&#%& Excerpted from Xen-devel mailing list (3 partial messages) #%&#%&#%& (1) On the VT-d troubleshooting page, I was informed to shoot you all a message if Xen had to deactivate my VT-d due to errors in my BIOS (in this case Coreboot). I am running John Lewis' Coreboot ROM for the Chromebook Pixel 2 (samus) w/ the i7-5600U processor and Xen 4.4.2 on Qubes. I downloaded and cracked open (for lack of better words) John Lewis's Coreboot image (which is a modified version of the one in the Google repos) and found that src/arch/x86/acpi.c had the same section added by the http://review.coreboot.org/#/c/1654/ commit written by Patrick Georgi a few years back that is supposed to provide ACPI DMAR tables. The problem might just be the code is out of date for modern processors or maybe it has just not been tested against many CPUs. It does appear that there has been changes to this acpi.c file in the Coreboot master branch, which makes me wonder if building against that would fix my problems. Realistically though, I have barely any experience or knowledge with Coreboot hacking and I'm assuming there is a web of dependencies that I couldn't figure out without possibly months of research, trial, and error. &%#&%#&%# (2) Please reboot and use "iommu=verbose,debug" on the Xen command line, which will offer more information. ~Andrew &%#&%#&%# (3) I was already passing iommu=verbose, but not debug as well.

[PATCH 0/4] Libflashrom
by Łukasz Dmitrowski Aug. 15, 2015

Aug. 15, 2015

Hello, I improved and extended libflashrom patch, so I am posting it for a second review. I based on work of Nico Huber and Anton Kochkov. As Nico Huber's patch has been already sent some time ago I will send only Anton Kochkov's building and compilation fixes (thanks for sharing it with me) and my changes. Content: 1 / 4 - Fix libflashrom compilation (by Anton Kochkov) 2 / 4 - Fix libflashrom building (by Anton Kochkov) 3 / 4 - Added querying functions to libflashrom 4 / 4 - Added function which returns string list of multiple chips found I will be grateful for your opinions - it helps me to improve the patch. All this code you can also find here: https://github.com/lukaszdmitrowski/flashrom/tree/libflashrom Regards, Lukasz Dmitrowski
