08:58 DottorLeo: Hi! I'm trying to bisect a regression between 25.3.6 and 26.0.5 but i have a lot of trouble to compile mesa. I've cloned mesa but if i try to compile an older version usually it stops with a subcommand failed error
08:59 DottorLeo: also, if i'm trying to bisect should i put the good/bad version as above or i should point to the 2x.x-branchpoint?
09:00 DottorLeo: For example, if i checkout the 26.1-rc3 i can build it without any problem and testing on my program
09:11 soreau: DottorLeo: for good/bad versions, you probably want to use the versions that have the least amount of commits between them. Sometimes, you might have to apply some patching to get a certain mesa commit to build or configure it so that it's only building the parts you care about. Also there is git bisect --skip
09:12 DottorLeo: i'm kinda doing it right now :D
09:12 DottorLeo: sometimes i need to do git bisect skip and it compiles :)
09:14 DottorLeo: i'm using Venemo github guide to build only radeonsi/radv mesa and a 7950X3D helps a lot :D
09:21 DottorLeo: ...it's strange all the commits are good for now ^^"
09:37 dschuermann: try bisecting from 25.3-rc1
09:48 DottorLeo: i've other information to understand where to start: i've tried 26.0.0 and 26.0-branchpoint. Still happens
09:48 DottorLeo: maybe trying 25.3.0?
09:49 DottorLeo: dschuermann: the rc are older than the first .0 release, right?
09:49 DottorLeo: if i understand correctly, when the 25.3.0 is released it's also the base for the future 26.x development?
09:55 DottorLeo: ok 25.3.0 works...so the good is 25.3.0 and the bad should be 26.0.0...or older?
09:59 DottorLeo: uhm....so 26.0.0-rc1 still hangs
10:00 DottorLeo: i think i'll go between 25.3-rc1 and 26.0-rc1....should be good?
10:09 DottorLeo: "Bisecting: a merge base must be tested"... why?
10:09 DottorLeo: i've put as good the 25.3.0rc1 and the bad 26.0.0rc1
10:24 Venemo: DottorLeo: what exactly is the issue you are bisecting?
10:25 DottorLeo: https://gitlab.freedesktop.org/mesa/mesa/-/work_items/15368
10:25 DottorLeo: finally the first hang within the bisection!
10:27 Venemo: ah, nice
10:27 DottorLeo: lunch break then i'll restart :) Pasta is waiting
