The patches have changed quite a bit since the RFC, and therefore I
didn't feel comfortable trying to do v2 information. I didn't feel
comfortable taking the few r-bs that I had from the RFC except for the
one patch that I applied wholesale.
Summary:
- Completely redid the patch splitting.
The number of patches increased, but LOC is about the same, and a
handful of the new patches are either because of more splitting, or
completely new bits.
- Reference counted context allows freeing the data structure and
freeing the BO independently. This is probably the most significant
change.
- Convert ILK RC6 code to use context code. I'm hopefuly this will make
things more stable, but have no proof.
- Added trace events for context create/destroy/switch.
- Only support render ring context switch (previous code supported any
ring, though media ring is the only other ring which *should* work).
Testing summary.
ILK
RC6, just booted to desktop
SNB
module load/unload testing
20 consecutive suspend resume cycles
nexuiz with experimental mesa
piglit quick.tests with experimental mesa
I've seen time-elapsed, and polygonOffset intermittently fail, I
believe this is caused by the following...
Missed IRQs now seem to occur once every other piglit run.
I have some new code to try to fix this... coming soon, I hope.
IVB
No testing done since RFC
I'll respond to this email with links to what I used to test (code is
currently not in pushable form).
kernel
libdrm
mesa
intel-gpu-tools
Thanks to Chris Wilson, Daniel Vetter, and Eric Anholt for providing
useful feedback in the RFC.
