I'll take a look. I've quite a few local changes I need to commit. Unfortunately, I can only build test, if you're willing to run-test, that would be great!

sjnewbury commented 6 years ago

I've got it building successfully. I will push all my latest changes to the repo today. Let me know if it then works for you.

sjnewbury commented 6 years ago

I will also add a stable gcc-8 release alongside the the live ebuilds.

sjnewbury commented 6 years ago

@vovagubin1987 That was a lot more work than I thought it would be. I now have a properly slotted offload-gcc-nvptx ebuild which works for both versioned and live compiler builds.

I'm about to push it, if you could test it, that would be great!

sjnewbury commented 6 years ago

I'm dropping sys-devel/gcc from the overlay so to use the plugin you'll need to use repos.conf to inherit the eclass for where your gcc ebuilds are located.

vovagubin1987 commented 6 years ago

I compiled gcc-nvptx 8.0 and gcc with offload 8.0 only with gcc version 6.4

sjnewbury commented 6 years ago

I suspect that kernel version is probably too old. The eclass only provides USE=offload-nvptx for version 7+.

sjnewbury commented 6 years ago

kernel? I meant compiler!

sjnewbury commented 6 years ago

I need to make sure the offload driver is added to DEPEND for the gcc build.

sjnewbury commented 6 years ago

I've fixed the dependency to the gcc version/slot.

All you should have to do is ensure your /etc/portage/repos.conf/gentoo.conf includes::

[DEFAULT]
main-repo = gentoo
eclass-overrides = gentoo-gpu

Then when you emerge sys-devel/gcc:8 with USE=offload-nvptx it should pull in the appropriate version.

I'll add ebuilds for all the current (suitable) portage versions.

sjnewbury commented 6 years ago

gcc-7.3 support is there now.

sjnewbury commented 1 year ago

Probably a bit late now, but I've been able to test and fix up the offloading support in conjunction with ROCm since I now have a GPU I can test with. I need to bump the NVPTX version, but I need someone willing to test it.
