MIPS GDB Buildbot slave running Debian Jessie

MIPS GDB Buildbot slave running Debian Jessie

[Brendan Kirby]

I'm interested in setting up a GDB Buildbot slave on a MIPS board.  The
board is an Edge Router Pro board running Debian Jessie. I've
configured, built and run the GDB test suite on it based on the steps
other builders are using in the GDB Buildbot master.  Due to what looks
like I-cache coherency issues in the kernel the board needs to be run
with no SMP.  Otherwise it builds and runs the test suite correctly. 
We're passing over 23,000 of the GDB tests, but we still have 400 to 500
test failures.  Would it be possible to get this board added to the GDB
Buildbot?  If so, could you send me or point me at the config.json and
the master.cfg files so that I can send a patch?

Thanks,

Brendan Kirby

There is no I cache coherency issues I know with respect of the octeon inside the edge router pro. Maybe it is just kernel version issue. I would run 4.1 on it as that should have most if not all octeon support in it.

Andrew

I'm actually running the 4.1.1 kernel from kernel.org on this board.  I
can send the results from a big and little endian run if that will
help.  Also, I can try it on 4.1.2 which I think just came out last week.

Hi Brendan,

Yes, your MIPS buildslave would be very welcome to our BuildBot!  In
order to simplify things, you can send me an e-mail offlist with the
following information:

- name of the buildslave;

- how many jobs it can handle when compiling/testing (i.e., what is the
  value of N in "make -j<N>")

- what types of builders do you want to assign to it (I suppose it will
  just build the plain GDB, i.e., no
  native-gdbserver/native-extended-gdbserver)

- the admin's e-mail address (BuildBot will send an e-mail to this
  address if the slave gets disconnected)

Also, don't forget to edit the "config/{info,host}" files (under your
buildslave directory) and put useful information there (take a look at
the "Slave information" section on any buildslave page to see examples).

After I have everything, I will generate a password for the slave and
send it to you, and you will be able to connect it to our BuildBot.

Thanks for the offer!

FWIW, the MIPS buildslave is now running in our BuildBot.  Thanks to
Brendan for the offer!
