答复: can I keep all the messages printed out? how to enable memory usage profile?

[侯雨]

Hi Jose,

Thank you for your quick reply. It is on Windows, and  the hardware is Intel HD 3000 and 2000, and the operating system is WIN732/64 and WIN10,  private bytes in the tested process and VRAM consumption rocket up on WIN7, even the textures and frame buffers seems to be deleted correctly, if the software was left untouched for some time, the memory may fall down slowly by itself, but in WIN10, it seems ok, memory may fall down and won’t touch the limit. I doubt the private bytes is aligned with the reported PAGED memory, but haven’t confirmed, and not knowing where the private bytes are “alloc”ed, seems it is occupied in driver, do you have any idea?

The TODO is really attractive. ☺

Hi, all,

I am trying ApiTrace to check the performance of a software, when “lookup state” on some frame/function, there are messages shown in error dock, which I concern is a message on buffer info, there is information on mem usage on different memTypes, my questions are:


1.       what does PAGED type stands for? Can I get where it is used?
That message is provided by your OpenGL implementation, not apitrace itself.  You'll need to lookup the GPU IHV documentation.

2.       After showing the message for some times, there are indication of “too many identical messages, ignoring” and no more displayed, can I get them all?
Not yet -- https://github.com/apitrace/apitrace/issues/395 -- but note that every message causes the UI to load all calls of the frame where it lives, so too many messages can easily eat up all your system's memory for large traces.

Note that you'll still get _different_ messages  -- messages with other IDs will still be displayed.  That is, the message limit is per message ID.

3.       There is profile function in menu and “memory usage” tick box in dialog box, but seems no output, where to find the result?
This was on Windows right?  Memory usage is not implemented on Windows.  I should greyed it our or implement it.

4.       Why is Intel integrated card consuming memory increasingly, can program release them with some API?
It depends.  apitrace's glretrace program consumes memory for its own internal purposes -- not all memory of that process is used by the OpenGL driver.  It's also possible your app is leaking GL resources too.
