With the updated graphics recipes in meta-ti this hack is no longer needed.
Did you test that? What board and with what program?
If I remember correctly, there was a build failure in the past with newer
Weston complaining that the extenstion does not exist in the old binary DDK.
Since I haven't seen this failure with the updated Mesa-based graphics stack,
I assumed that is now resolved.
My testing was mostly with Rogue and I see in the commit log that this is
specific to SGX, which currently builds full software-rendering stack w/o any
HW acceleration.
Is this extension a pure software implementation in Mesa or does it require
corresponding HW support? If the latter, then we definitely still need this
revert and my patch removing it can be dropped.
Unfortunately it needs to be handled in the GPU driver on the UM side, so
not something Mesa can fix for us. And the error only shows up as a runtime
issue when you try to start Weston and it sees the extension is not available.
We will need to keep this patch until someone can add the software emulation
of this function inside the SGX UM driver. It is on my todo list for someday..
Andrew,
Thanks for confirming.
Ryan,
We still need Andrew's revert, please drop my patch from the queue. Thanks.
Roger that.
