13:20 <freemangordon> enunes: if you remember, you provided us (leste guys) with a hack to implement EGL_BUFFER_PRESERVED swap behaviour, noting that we shall implement EXT_buffer_age. I started to work on that, but buffer age is always zero, ending in full redraw. Is that expected or do I miss something?

13:21 <freemangordon> the hack in question: https://github.com/maemo-leste-upstream-forks/mesa/commit/dde856128e67b0d3760cd3b8fa95c4c1463168bd

13:42 <enunes> freemangordon: I'm not sure, though as it was never enabled upstream I suppose it goes through a lot of untested code

13:42 <freemangordon> enunes: umm, what was not tested? EXT_buffer_age?

13:42 <freemangordon> maybe I was not clear enough:

13:42 <enunes> I miss the context about this, need to look at the issue again

13:43 <freemangordon> I *reverted* the hack

13:43 <freemangordon> and *do not* request EGL_BUFFER_PRESERVED

13:44 <freemangordon> and I expect eglQuerySurface(dpy, surface, EGL_BUFFER_AGE_KHR, &age); to return age that is != 0 somethimes

13:44 <freemangordon> but age is always zero

13:44 <freemangordon> like if back buffers are not recycled

13:47 <enunes> still dont have the whole context back in my head but age 0 does not seem right, https://registry.khronos.org/EGL/extensions/EXT/EGL_EXT_buffer_age.txt says age 0 means contents undefined or single buffered surface

13:48 <freemangordon> yes

13:48 <enunes> do you have a link to the issue?

13:48 <freemangordon> lemme check

13:52 <freemangordon> enunes: ^^^

13:55 <enunes> yeah I don't know what can be happening there, I guess to debug further it might be better to try with a very simple demo application and see how it behaves there

13:57 <freemangordon> I am building mesa with debug symbols, once I have that will let you know what happens in dri3_query_buffer_age

13:57 <freemangordon> (witt debug symbols and -O0)

13:58 <enunes> I think the more helpful thing is really to see how a very dumb and simple application behaves, before diving into the debugger

13:58 <freemangordon> I am using dumb and simple application

13:58 <freemangordon> using clutter though

13:58 <freemangordon> like, it just moves a texture over the screen

13:59 <freemangordon> but ok, will try to find some even simpler example

14:39 <freemangordon> enunes: scratch that, it was my fault

14:41 <freemangordon> sorry for the noise
