Hello Gregory,
time for an update/rebase (after Timothy's GREAT work on 'no error').
Your Patchwork series (v5-x-y) didn't apply anylonger after commit
f96edf7.
Greetings,
Dieter

Hello,
Please find the latest version that include a small fix for hash
deletion. I
think the series is good now. Please review/ack it.
Allow to handle this kind of case:
genBuffer(&pbo);
BindBuffer(pbo)
DeleteBuffer(pbo);
BindBuffer(rand_pbo)
TexSubImage2D(user_memory_pointer); // Data transfer will be
synchronous
There are various subtely to handle multi threaded shared context. In
order to
keep the code sane, I've considered a buffer invalid when it is deleted
by a
context even it is still bound to others contexts. It will force a
synchronous
transfer which is always safe.
An example could be
Ctx A: glGenBuffers(1, &pbo);
Ctx A: glBindBuffer(PIXEL_UNPACK_BUFFER, pbo);
Ctx B: glDeleteBuffers(1, &pbo);
Ctx A: glTexSubImage2D(...); // will be synchronous, even though it
_could_ be asynchronous (because the PBO that was generated first is
still bound!)
V3: I mixed up the number so I jumped right away to v4...
V4: improve commments based on Nicolai feedback
V5: Properly delete element of the new hash (first patch)
Best regards,
Gregory Hainaut (3):
mesa/glthread: track buffer creation/destruction
mesa/glthread: add tracking of PBO binding
mapi/glthread: generate asynchronous code for PBO transfer
