Neither blender nor clinfo recognize it

I guess the ocl-icd loader is shit

@hedmo

is there a way to override the settings in ltoworkarounds.conf without changing the file. dev-lang/perl compiles with lto for me but not without and i dont want to change the settings every time i sync to the overlay

Jannik2099

@Jannik2099

It's a git repo

You can commit your changes to your local repo and sync, and it'll keep them

@hedmo

i am using layman and if i make a change layman wont sync.i have to delete the repo and add it again to have it sync.i have to learn more about git before i walk that line.one thing i have had in mind was to fork the repo,mod it for gcc-10 or some thing like that but i need to learn more for that.

Jannik2099

@Jannik2099

that should work with layman aswell

as long as you set the sync type to git

cd into overlay dir, git add . , git commit, sync

@InBetweenNames is it ok to add issues with gcc-10 and gentooLTO on your git? i have manage to work my way almost thru on two boxes with gcc-10 and gentooLTO.here is a topic on the gentoo forum : https://forums.gentoo.org/viewtopic-t-1106836.html

@Jannik2099

oh boy

so uh, it seems like OpenMandriva compiles a lot of packages with pgo

We have to port this to gentoo, it's our duty

Regarding GCC 10, I just have up. Boost has that weird sed problem, which is problematic, since emerge boost results in some NumPy pain points surfacing (--emptytree is fine for whatever reason). That was today. Thanks to two power outages, my GCC 10 experiment has dragged on for almost a month, whereas rebuilding the entire world with GCC 9.2 takes about five days without --jobs (I only discovered that flag after I started experimenting). Well, the two power outages plus encountering that sed issue multiple times per day certainly did not help the speed of the rebuild.

Regarding OpenCL, rocminfo gives me some weird error regarding insufficient resources to run, but I will sort it out later (I tried to check before the power went out the first time).

Regarding Mesa, my report will not be of any use, since it takes several hours to compile and a full day to build (and once again for the 32-bit binary). As far as the USE flags go, I have both Radeons enabled because Steam throws a tantrum otherwise for whatever reason (I had Mesa built with RadeonSI only, but Radeon seems to be a hard requirement for Steam). I have VDPAU and a few other USE flags enabled as well.

@Jannik2099

Currently running steam in flatpak... Talking about which, it should be possible to use system mesa in flatpak

I fear the OpenCL loader is broken, I'll try install the rocm one

regarding GCC10 i have switched to it on my 3 boxes .one laptop=area51m,one ryzen 1700 with radeon rx580 and my server with intel i3 ( -march=sandybridge) inside.i have no problem building the worlds on them with some -fcommon and -flto overrides.dhcpcd and dhcp is failing to configure the ip address so i left them on GCC9 at the moment and it is working for now.the kernel compiles but is not bootable. i am running steam on the area51m and the rysen box.and having minecraft-server running on my server for my doughter to playing with friends.i dont use OpenCL

Im Posting A Lot Of Stuff About Gentoo

Videos Of All My Projects LOL

Thanks To Lto-Overlay

My Gentoo SystemD Glibc Works Like A Charm I Have It Working Since January Of The Last Year When I Started Using Gentoo-Lto Overlay All Its Optimized With LTO PGO Graphite -o3

etc

So I Move On And I Have It Still Very Nice And Dandy Beating Windows OSX at Gaming On Citra 3ds Emulator

And My Project Blue Virtual Dragon Gentoo/Musl Compiled With Clang And Gentoo-LTO Overlay Enabled Too With Some MODS to Work With Clang ThinLTO And More

@javashin

This Linux Works Like A Charm Too

Also I Have A Pre-patched Kernel Called REALTIME-X That Can Be COmpiled With GCC OR CLANG And Have A Lot Of Nice Stuff I DId A VS . of REALTIME-X LTS v5.4.18 VS v 5.5.2 Vanilla LAst Stable RELEASE

And My Kernel Won

Im Very HAppy

Also on The Same Github I Have A Distro Maker How TO Scripts To Compile FreeBSD 13-Current And Upgrade The Whole Graphics Stack And Make FreeBSD Fast As HEll

On Par To Linux

Or Better

@hedmo

@javashin how about building your kernel with GCC10?

Jannik2099

@Jannik2099

Anyone had success with firefox 73 and lto / pgo?

Jannik2099

@Jannik2099

Ah, seems to be an older gcc bug that reappears every now and then. -flto-partitions=1 should fix it, will try later
