sincerely consult about Gerrit plugin

Dear Mr/Ms， I am very excited to read the slide "Gerrit: how to cook a plugin in only 10 mins". Now I have a problem about how to build a gerrit plugin to display all the projects' name. Could you help me? Firstly, I built the gerrit platform and achieved the servertime gerrit plugin (the example in the slide). In the attachment, you can find the achievement of this step (servertime.png). Secondly, I followed the flow of the servertime gerrit plugin, I build a new java file (ProjectList.java), and I want to get the list of all the projects' name in the Gerrit through this projectlist gerrit plugin. In the attachment,I just write the head of class ProjectList (projectlist.png), I don't know whether it is right. Could you tell me how to write the class ProjectList to get all the projects' name? I am looking forward to hearing from you. Best Wishes, Zhaoguo Liu National Key Laboratory of Cognitive Neuroscience and Learning No. 19, XinJieKouWai St., HaiDian District, Beijing 100875, P. R.

If Nico is willing to push the code to coreboot.org then I think a separate repository on coreboot infrastructure is the perfect place. //Peter

Acer Chromebook 15 debug
by John Lewis 29 Aug '15

Hi Guys, Coolstar Organisation wants to do his Windows thang with one of the Broadwell Chromebooks, so I'm trying to build a working ROM with https://chromium.googlesource.com/chromiumos/third_party/coreboot/+/firmwar… to give him a hand. Luckily USB debug works with this, so here is what I'm getting. What could I do next? -John. coreboot-5cbe3a8-dirty romstage Sun Aug 23 12:18:55 BST 2015 starting...

coreboot as a system startup device
by Gregg Levine 29 Aug '15

29 Aug '15

Hello! Is Google using coreboot as a method to start and manage its systems? Especially since the open source gang at Facebook of all places is realizing that the bottleneck towards getting their systems to run capably happens to be its low level firmware. Of course the chap at the NYLUG meeting for Wednesday 8/26 all but admitted that they were using Intel based servers back there, so I did not mention what goes on here. The presentation should be up on the NYLUG Youtube channel in a matter of weeks. ----- Gregg C Levine gregg.drwho8(a)gmail.com "This signature fought the Time Wars, time and again."

Besides that, SPARK gives us easier provability of code. That is something governments and safety engineers care about, and it makes for great marketing. > What harm would it do? Having it in the tree would be beneficial because it will be easier to bisect than two separate trees. The only thing I'm worried about is whether we can guarantee the complete tree can be built on all of the platforms where it can be built now, but that worry applies in the git submodule case as well.

If this > can make our code base better in some way, why not use it? I'm not concerned about the language. More about the content `device driver`, which could be used anywhere (actually, I first planed to use it in FILO, why is coreboot doing gfx init anyway?). Also, I was bothered some- times when code got copied from coreboot to libpayload or the other way around. I don't know if the real problem was that libpayload resides in it's own repository. But having simple device drivers in it's own place seems to be a good idea, for me. Anyway, I'll push it next week (I guess) when the code got cleared.

If you can provide portability guarantees for userland compilers like we do for target compilers... (which is one of my main worries right now: gnat requires an ada compiler to build itself, but even that is pretty portable compared to what's going on with golang) Patrick -- Google Germany GmbH, ABC-Str. 19, 20354 Hamburg Registergericht und -nummer: Hamburg, HRB 86891, Sitz der Gesellschaft: Hamburg Geschäftsführer: Graham Law, Christine Elizabeth Flores
