Hi,
I've started to play with Multicore visualizer
(org.eclipse.cdt.dsf.gdb.multicorevisualizer.ui).
My objective is to visualize the Kalray MPPA (it's a device
with 288 cores) in Eclipse, during a debug session.
Cool! We are very excited to have you join to work on the
multicore visualizer. With the high number of cores on the
Kalray chip, it will be interesting to see how this goes.
Next step is to connect multicorevisualizer with the MPPA.
It seems the MultiCoreVisualizer relies on IGDBHardwareAndOS
service to retrieve CPUs, Cores, and Threads.
So I guess I've to provide my own implementation of this
class ?
I think so. Depending on how linux-like your application looks
through GDB, you might be able to re-use some of the existing
implementation.
However you'll likely need to at least re-implement the part
that finds-out the number of CPUs/Cores (by looking in
/proc/cpuinfo - which is very Linux-specific). You probably
will want to add some Kalray-specific entities in there, in
addition to the CPUs/cores (Sorry - I do not remember the
details, but I think you have a concept of group-of-cores,
that might be useful to add in there).
More generally, have you any hints on this topic ?
We are working on the first iteration of the Epiphany
Visualizer right now. It's based on the Multicore Visualizer,
strategically overriding some parts of it. We will be
presenting this work at EclipseCon next month. We are going to
start working on the IGDBHardwareAndOS part later this week -
it's the biggest part left. We might be able to share some
code in a couple of weeks, if you are interested to have a
look. I attach a couple of recent screenshot of the EV.
Regards,
Marc
