[Xen-devel] Outreachy bite-sized tasks

[Roger Pau Monné <roger.pau@xxxxxxxxxx>]

Hello,

First of all, thanks for your interest in the Xen Project, and for wanting 
to participate in Outreachy.

Both of you have expressed interest in the "QEMU xen-blkback performance 
analysis and improvements" Outreachy project, and AFAIK both of you still 
need to perform your initial contribution.

I've found a couple of small tasks that you can perform and should allow 
you to complete your initial contribution to the project:

 - The first one is related to xenalyze, and it consist in creating a 
   header file that can be shared by both the Xen kernel and xenalyze.
   You will need to move the TRC_ defines found in sched_credit.c and 
   sched_credit2.c to a header that's shared with xenalyze and then 
   replace the usage of TRC_SCHED_CLASS_EVT with the defines in the header 
   file [0].

 - The second one consist in fixing the return codes of certain xl 
   commands. There are commands in xl that will return 0 (SUCCESS) even 
   when failing, which makes it very hard to write scripts that make use 
   of xl. A list of those commands can be found in [1], together with some 
   preliminary patches. Please note that those patches have comments that 
   you will need to address, and that you should also need to preserve the 
   original authorship of the patches plus yours.

I encourage you to read the wiki page about sending patches to xen-devel 
[2], it should guide you through your first steps on using git and 
creating suitable patches.

Also, please note that this is an open source project, so you will need to 
coordinate in order to figure out which task are you going to take, in 
order to avoid clashes or duplication of efforts.

If you have further questions, either reply to this thread (keeping 
the xen-devel mailing list on the Cc), or feel free to start another one 
if you think it's more suited.

Roger.
