Your suggestions helped me a lot in reaching the following conclusions. I tried a couple of things, as Peter suggested. I managed to build a ROM from their tree. It didn't work since it was written for a different board. I pulled in the romstrap table from my board, and the early serial init. That also didn't work. It could be that their code reconfigures the cpu to nb bus in a way not suited for my board; I haven't dug too deeply into the issue. That configuration is best left in the romstrap. Since the raminit code is fairly isolated, I pulled it into my branch, and spent about half a day getting it to compile. I spent a little time finding out why the meat of raminit code is not called, until I found out it was looking for a SO-DIMM. That's already a red flag. The code from VIA has a ton of tables with delays and driving values for DRAM. The most important parameter, how much to wait before reading each set of DQ pins, is also preset. That preset is different than what I have been using. Needless to say, raminit fails. The presets are board-specific. Other than the presets, I can't see anything fundamentally different from the raminit algorithm that's on gerrit. I don't think the effort of rebasing the VIA code is worth the benefits (not even sure there are any benefits -- the gerrit code does the same thing with 20 times less LOC). I'll have to play around with it some more, see if I can get it working. Right now, it looks like the VIA code serves better as a HOWTO (or HOWNOTTO) guide. Will post updates (either here or on IRC).

Rebasing a 2009 branch on current master (VX900 anyone?)

by Alex G.

Hi, I am that guy that never seems to get VX900 working properly. I've recently received some code[1] for the VX900 from VIA. It is based on a coreboot fork from about 2009. Rather than try to continue my own VX900 effort, I think it is better to use the code provided by VIA, and clean that one up. I don't have the SVN history for the code, but Cristi was able to trace it back to somewhere around hash a9c5ea08d07d343d32d4c083a232107bd84d8064 VIA has no interest in maintaining or rebasing the code, so we're on our own here. The good news is that using this code will reduce the time needed to complete the VX900 port significantly. I therefore ask the gurus, "What is the best way to go about this?" Let's hope we can get this code working with our current master. If we manage to rebase it, I can clean it up, and optimize it a bit.

Adding checks for non-ASCII filenames (was: [Gerrit] gitconfig: Add sample checks shipped by git to pre-commit hook)

Dear coreboot folks, Am Donnerstag, den 30.05.2013, 01:57 +0200 schrieb gerrit code review: From <http://review.coreboot.org/3336>: > Change subject: gitconfig: Add sample checks shipped by git to pre-commit hook > ...................................................................... > > > Patch Set 2: Code-Review-2 > > It does not make sense to have a hook that checks a tree-wide policy > and then allow that policy to be disabled by configuration. Either we > decide on the filename policy or we do not need the hook. as non-ASCII characters are not allowed in our source [1], I assume they are also not allowed in file names. The sample pre-commit hook shipped by git has a check for non-ASCII file names, which can be disabled by a config option. Are there any circumstances where non-ASCII characters might be needed? If not, Peter is right and the option can be removed from the script, which I would do then. Thanks, Paul [1] http://review.coreboot.org/2604

Re: [coreboot] Lenovo X301 information

by Cristian Măgherușan-Stanciu

Hi George, The chip is there and it was easy to find it, but it's a less common package. It is an 8 pin part but wider and closer to the surface than the SOIC8. I tried the Pomona clip and even if the pins would match after mounting the clip, it makes no electric contact to it due to the smaller leads, so Flashrom couldn't detect it. The next step is to solder some wires and make it writable from outside using my RaspberryPi external flasher. The rest of the hardware is quite well supported by coreboot. It is somehow similar to Roda rk9 (same CPU package, NB and SB) but with the rest of the chips(EC and company) similar to other Thinkpad laptops, so in theory a port should not be so hard.

Re: [coreboot] Trying to get coreboot running on VIA EPIA-M (lzma: Decoding error = 1)

by ron minnich

a few things. Don't know why the MTRRs are not supporting all of memory but you ought to fix that. Can you get rid of the vga bios? That will save some time. I forget the last thing :-) oh yeah, when you get it for real, turn down the default console log level to ERR. Printing takes a surprising amount of time. ron

Re: [coreboot] Trying to get coreboot running on VIA EPIA-M (lzma: Decoding error = 1)

by Marius Schäfer

Ok, I don't know why, but I now can run compressed and uncompressed filo as payload. I even got vga to init and display the output from filo. If I try to use SeaBios as payload, I still encounter lzma errors. I can't test SeaBios uncompressed as it's too big for my 256kB flash. But I could be quite happy with filo as I just want to boot the Linux kernel very fast (faster than the original Bios and syslinux do). I try to build a headless mpd player with buildroot. With the regular Bios and syslinux it takes about 20 seconds from power up to playing music. I think I could save about 5-10 seconds with coreboot. Can you read anything out of these lines and help me?

So it's doable. Right. My point is just that there's not some special atom function you can call to do all of that. You have to walk the topology and light up the displays. Alex

Re: [coreboot] Native init for AMD cards

by Rudolf Marek

Hi David, > I read the kernel sources today, looking for a way of doing native init for AMD boards like the F2A85-M. > Comments welcome on the insanity of this proposal :) In fact I did the same some time ago, but there is a problem with the AtomBIOS and the graphical data paths. > 2. Do coreboot developers have contact with the radeon driver developers? A > little nudge from time to time could keep a project like this on track. I was speaking with Alex (I put him on CC) My Q was: > My plan (which may sound bit naiive), is/was to Initialize the GPU with > AsicInit (so simple run of AtomBIOS interpreter) and then switch it to legacy VGA > mode and handle this with SeaBIOS VGA BIOS. Maybe there is a gap between - > setting up a legacy VGA and AsicInit, I don't know, possibly I need to detect what kind of output is used, but all I need is simple text mode > > Please can you throw some light on this topic? Alex told me: The AsicInit table just performs low level setup on the asic, it doesn't mess with the displays at all. The radeon vbios has real mode x86 code that gets executed at post or via vbe calls to read in the information in the atombios tables, figure out the display topology and detect and light up whatever displays are attached. You would need to implement that functionality in your vbios replacement. If you want a bios console, you'll have to use the open source radeon driver as a guide to how to write a vbios replacement that enumerates and lights up the displays. END Also it turned out that the bytecode is there for the OEM so the changed topology does not need the new VBIOS assembly but just the AtomBIOS bytecode. Which is quite bad, because the VBIOS is depending on how it is routed and may only work with similar boards even when chipset is same. We would have to find out a way how to include the AtomBIOS in some form in the coreboot or re-write it somehow, because the bytecode is not even "property" of AMD but OEM and radeon driver needs that to be present in a rom. Maybe it would be possible to write some commmon init and handle just small changes in the bytecode. For now, I would say kind of "reply" init might work, it depends if your goals are similar like we have with intel, so just graphic framebuffer for grub2 or something like I had in my mind. Thanks Rudolf
