building Mesa 21.2

I am very exciting to try out "Crocus", the new Gallium 3D Driver for older Intel Hardware.
I succesfully built and currently use other versions of Mesa by manually applying the patches from /usr/ports/graphics/mesa-dri/files.
This does not work anymore. After generating the build files with:
meson .. -Dvulkan-drivers= -Ddri-drivers=i915 -Dgallium-drivers=crocus -Dllvm=disabled -Dgles1=disabled --buildtype release
Building Mesa from git master now results in:
Code:
/include/c11/threads_posix.h:143:10: error: calling function 'pthread_cond_timedwait' requires holding mutex 'mtx' exclusively [-Werror,-Wthread-safety-analysis]
    rt = pthread_cond_timedwait(cond, mtx, abs_time);
With the full log of meson and ninja being here:

Anyone else happen to try to build mesa from git master?
 
Hello,

if you are interested in a bleeding edge Mesa, you should try graphics/mesa-devel.
that package unforunately runs on Mesa 21.1, not including the new gallium driver and no gallium driver is configured to be build with that one either.
But thanks for the reference, I will try to use the patches from that package to get 21.2 running.
 
I went through the patch files of mesa-devel and unfortunetly they do not address issues with include/c11/threads_posix.h:143:10
Seems The jump from 21.1 to 21.2 introduced much new stuff...
 
I would suggest contacting the maintainer of graphics/mesa-devel. I see there's been an update commited (adding an option for 'crocus') just yesterday, so he's definitely working on it. Just ask if there are plans for importing 21.2.

"expose crocus to replace i965"
*happy noises*

Thanks for the reference. Indeed, the package maintainer is propably the best person to ask on how to build and contribute back patches.
 
The port itself works and is actually internally reported as Mesa 21.2, though the port refers to it as 21.1, since 21.2 did not release yet officially.
There are issues like image corruption and GPU Hangs, but that is Mesa related and I started addressing it in the mailing list: https://lists.freedesktop.org/archives/mesa-dev/2021-July/225438.html

Many thanks to the maintainer of this port, truly the bleeding edge of FBSD.
