I've gone ahead and pushed the Vulkan drivers meson builds.
For those interested in helping finish the conversion, I have a branch
"wip/meson-4" on my github (github.com/dcbaker/mesa) that has i965 and most of
the core classic mesa stack building. I'm working on GLX, then EGL to start
testing this stack. Getting gallium building is my next step after that (it'll
be RadeonSI because I have hardware).
I'm also working on getting features into upstream meson to make meson more
comfortable for mesa. Currently there are patches landed or pending for the two
workarounds in the meson build we have currently (choosing the right linker and
indexing into CustomTargets). I'm also still thinking about how we can share
source files with the other 3 build systems already in mesa (autotools and
android being the most important, since hopefully our meson will be able to
support windows in the future, I don't know what will happen when android moves
to blueprint/soong). If there is anything else please let me know.
Talking with ChromeOS folks at XDC, it sounded like having Android.mk be
a small wrapper around another build system is a totally acceptable and
not unusual thing to do. Rob, does that seem possible/OK to you? It
seems like that should seriously reduce the android maintenance burden.
I haven't come across any examples doing that, but it seems fine to me
if that can work. I'd guess we just need to create a prebuilt target
and somehow trigger it to run meson. It could be problematic if
anything in mesa is a dependency on another project as there's some
expectations about where things are built. But I don't think mesa is a
dependency for anything.
One possible issue is that meson and its dependencies are not part of
the supported toolchain for Android, would be surprised if this does not
become a problem on some level. As example version of Meson on Ubuntu
LTS (which is the tested and supported distro for android building) is
0.29.0 while on Fedora 0.42.0.
