982268 - improve b2g-info threads display

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: GonkIntegration, defect, P3)

Description

[Ben Kelly [:bkelly, not reviewing]]

Attachment: b2g-info-threads.patch

While working on bug 980027 I patched b2g-info to provide some additional information about the process threads.  In particular:

* system priority
* RT priority
* scheduling policy

I'm attaching my work-in-progress patch here.  It needs to have some additional headers added for the threads as its a bit confusing what each column means.  Also, the expanded regex seems quite slow.

A pevious version of process.cpp used fscanf

It might be interesting to try that from a performance standpoint.

However, I think you need to make it read in the line, scan from the beginning to look for (, scan from the end to find ), and then use sscanf on the portion to the right of )

ENOTIME to work on this unfortunately.  Unassigning for now.

Mason, you may want to look at these patches as they are useful for inspecting the RT priority of threads.  Could be helpful with project silk.
