List of ideas for coreboot meeting on Sunday and Monday in Berlin
by Paul Menzel 24 May '13

24 May '13

Dear coreboot folks, as you all know after LinuxTag [1] there is going to be a coreboot workshop/hackfest/you name it/meeting on Sunday and Monday [2]. The Infrastructure Projects page in the Wiki [3] lists a lot of things, which we can hack on, and on Sunday morning it is planned to have a planning session for what to work on. If you already know of something which should be mentioned in that session, just name it here in a reply as it won’t hurt to think about that beforehand already. I start by listing with what I heard already and my suggestions. (No order of priority.) General ======= 1. Think about ACPI and romstage.c unification. AMD === AGESA ----- 1. Implement `EARLY_CBMEM_INIT` for at least AGESA boards. 2. Get timing stuff working. 3. Integrate AGESA debug into Kconfig. 4. Optimize boot speed. 5. Suspend to RAM and resume for the ASRock E350M1. 6. Test DDR3 modules on the ASUS F2A85-M. 7. Fix the ASUS M2A-VM patch and commit it to corebootv4 repository. 8. Port the ASRock A780FullHD. GeodeLX -------- 1. Try coreboot on the MiniPC system with a LX800 board. Intel ===== 1. Get native graphics init working on the Lenovo ThinkPad X60 (and X201). Thanks, Paul [1] http://linuxtag.de/2013/ [2] http://www.doodle.com/p4ea9wz3bg96dveh#table [3] http://www.coreboot.org/Infrastructure_Projects

ASRock E350M1: Linux reports `piix4_smbus 0000:00:14.0: SMBus base address index region 0xcd6 already in use!`
by Paul Menzel 23 May '13

Dear coreboot folks, since [1] commit df729d7778a7e5878fac5545883f68e42372456a Author: Jens Rottmann <JRottmann(a)LiPPERTembedded.de> Date: Tue Feb 19 14:46:31 2013 +0100 AMD Fam14 boards: dimmSpd.c: Set `iobase` to `SMBUS0_BASE_ADDRESS` instead of `0xB00` which I expanded to the ASRock E350M1, overlooking the new error message, Linux complains about an already used base address index region. calling i2c_piix4_init+0x0/0x1000 [i2c_piix4] @ 559 piix4_smbus 0000:00:14.0: SMBus base address index region 0xcd6 already in use! piix4_smbus: probe of 0000:00:14.0 failed with error -16 The address 0xb00 was used before and this should not have been changed with the patch above. But it did. I looked through the code but could not find where 0xcd6 comes from. Any pointers would be very much appreciated. Thanks, Paul [1] http://review.coreboot.org/2453

I understood the code the way, that this is only needed, when autodetection fails. But the values should be autodetected. Maybe you can add some output in the loops above to see where it actually fails. As a workaround you can try to hard code your values though. > Option B is where AGESA says: > > > Going into training stage 2.

Maybe there is an option in AGESA where you can limit the maximum frequency. $ more src/mainboard/asus/f2a85-m/buildOpts.c […] #define BLDCFG_MEMORY_BUS_FREQUENCY_LIMIT DDR1866_FREQUENCY […] #define BLDCFG_MEMORY_CLOCK_SELECT DDR1600_FREQUENCY […] > I put a sample log at https://gist.github.com/davidhubbard/5552910 Thanks.

The board does boot, but only at DDR667.

Recording the LinuxTag talks
by Carl-Daniel Hailfinger 21 May '13

21 May '13

Hi, would someone please be so kind and record the coreboot talks at LinuxTag? A few of my colleagues can't be at LinuxTag, but they have expressed interest in watching the talks if any recording is made available. Thanks in advance! Regards, Carl-Daniel -- http://www.hailfinger.org/

S3 fails to suspend after wake up from USB keyboard
by WANG Siyuan 21 May '13

21 May '13

Hi, I am trying to debug an issue on Parmer. 1) use "pm-suspend" to suspend. 2) use USB keyboard to wake up. 3) use "pm-suspend" to suspend. FAIL To SUSPEND. After wake up by USB keyboard, I got some errors in dmesg: [ 55.585935] Disabling IRQ #9 I don't know why this is happened. It seems that ACPI method (_PTS, _WAK) have nothing to do with suspend and wake up. Does anybody can help me? 1) What is the workflow of USB keyboard wake up from S3? 2) What are differences between power button wake up and USB keyboard wake up? dmesg: [ 55.585874] irq 9: nobody cared (try booting with the "irqpoll" option) [ 55.585880] Pid: 691, comm: X Tainted: P O 3.6.11-1-ARCH #1 [ 55.585882] Call Trace: [ 55.585884] <IRQ> [<ffffffff810daffd>] __report_bad_irq+0x3d/0xe0 [ 55.585895] [<ffffffff810db2f3>] note_interrupt+0x1a3/0x1f0 [ 55.585899] [<ffffffff810e1bdf>] ? rcu_process_callbacks+0xaf/0x5b0 [ 55.585903] [<ffffffff810d8bcf>] handle_irq_event_percpu+0xbf/0x260 [ 55.585907] [<ffffffff8105e952>] ? __do_softirq+0x122/0x240 [ 55.585910] [<ffffffff810d8db8>] handle_irq_event+0x48/0x70 [ 55.585913] [<ffffffff810dbe0a>] handle_fasteoi_irq+0x5a/0x100 [ 55.585917] [<ffffffff81017502>] handle_irq+0x22/0x40 [ 55.585921] [<ffffffff8149c04a>] do_IRQ+0x5a/0xe0 [ 55.585925] [<ffffffff8149356a>] common_interrupt+0x6a/0x6a [ 55.585926] <EOI> [<ffffffff8149a4ed>] ? system_call_fastpath+0x1a/0x1f [ 55.585931] handlers: [ 55.585933] [<ffffffff812b758f>] acpi_irq [ 55.585935] Disabling IRQ #9 -- Yours sincerely, WANG Siyuan

Exposing performance data to user space/systemd
by Paul Menzel 21 May '13

21 May '13

Dear coreboot folks, as LinuxTag approaches and some of the systemd developers are going to be there, I remembered the discussion how systemd only supports exposing performance data on EFI systems [1]. Christian already brought up coreboot/SeaBIOS in that discussion. H. Peter Anvin (Syslinux) also voiced a need for a having that for non-EFI systems. Christin, are there any news? Thanks to the CBMEM console, the cbmem utility can read, and the timer work, we have performance data available now. If I am not mistaken, Chrome OS also supports reading these values. So maybe such an interface could be designed during LinuxTag and implemented afterward. If I am right about Chrome OS, do the developers have any suggestions? Are you content with your interface and can it be generalized for different boot loaders? Thanks, Paul [1] https://plus.google.com/115547683951727699051/posts/dXs8rrFQkLd [2] http://www.freedesktop.org/wiki/Software/systemd/BootLoaderInterface/
