My current TODO list for apitrace

[Carl Worth]

Hi folks,

I've got a bunch of things that I want to with apitrace, so I thought I
would share these ideas with everyone on the list for better
coordination.

These are sorted according to my current priority. I plan to tackle
these roughly in the order presented:

  1. Fix a few "apitrace trim" bugs

	People have given me traces where trim fails. I'll feed these to
	the stress tester and fix the bugs.

  2. Add a "GPU" row next to the "CPU" row in the profile timeline view.

	As discussed in my previous mail. If James (or anyone else)
	wants to be me to this, that would be great!

  3. Faster trimming

	I've already got some changes implemented that dramatically
	speed up "apitrace trim", (5x faster in one case I
	measured). These will be easier to submit after the trim code is
	merged upstream.

  4. On-demand tracing

	Trimming is sufficiently expensive that it would be nice to
	avoid the need to do it by simply capturing the desired portion
	of an application in the first place. So I'd like to have the
	ability to interactively start tracing when desired.

	My current thought is to take the state extraction of "glretrace
	-D" and write code that reads that JSON and sets that state into
	the OpenGL state machine.

  5. Compile traces to C

	I'm envisioning a modified version of "apitrace dump" that
	provides code that can be compiled to get a program that
	recreates the behavior of a trace.

  6. Move trace decompression to a separate thread

	To make it easier to get good numbers out of profiling trace
	replay.

  7. Even faster trimming

	Step 3 above has some first, obvious steps to make my current
	trim code faster, (replacing std::set<unsigned>), that I've
	already implemented. There are still some obvious slow spots
	that could be further improved.

-Carl
