05:38 PM seb_kuzminsky: hello developers, I want to release mesaflash 3.4.0. We've been on 3.4.0~pre1 since May 2020, and there have been some good fixes since then
05:38 PM seb_kuzminsky: does anyone know of a reason to hold off on releasing mesaflash master as 3.4.0 at this point?
05:43 PM roguish[m]: go for it.........
05:44 PM roguish[m]: get 'er done
06:05 PM Tom_L: i see no reason to wait
06:05 PM Tom_L: but i'm not a developer :)
06:10 PM seb_kuzminsky: i'm mostly wondering if jepler or pcw have any changes they're working on that they want to get in first :-)
06:11 PM jepler[m]: Not me
06:12 PM seb_kuzminsky: i just approved your mesaflash PR, want me to just merge it?
06:22 PM jepler[m]: Sure
06:24 PM seb_kuzminsky: done
06:31 PM seb_kuzminsky: with Steffen Möller's change to the mesaflash debian/control file, it'll no longer build on any distro older than stretch... but this change is required to get mesaflash into debian. So I think it's worth it? And if we want to support older distros we can figure out later how to handle backports in the debian way.
06:32 PM seb_kuzminsky: ODOD
07:11 PM jepler[m]: seb_kuzminsky: it also occurred to me to branch mesaflash 4.0 and say "welp it only is packaged on modern debian"
07:11 PM jepler[m]: "you can use mesaflash3 if you are suffering from ODOD (old distro ownership disorder?)
07:12 PM jepler[m]: apt install linux-image-rt-arm64
07:12 PM jepler[m]: I: /vmlinuz is now a symlink to boot/vmlinuz-5.10.0-8-rt-arm64
07:12 PM jepler[m]: BRB, checking if my pi still boots :)
07:17 PM jepler[m]: it does, I wonder how linuxcnc performs with debian's rt kernel
07:17 PM Tom_L: it that the mainstream kernel or an option?
07:37 PM * jepler[m] uploaded an image: (46KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/XUSrkrkCjUosZzpkTYjcvAnp/image.png >
07:37 PM jepler[m]: Tom_L: debian 11 has realtime kernels for amd64 and armhf, no need to build a kernel!
07:37 PM jepler[m]: however accelerated video may still not be working, I haven't tested that
07:38 PM Tom_L: i had heard about the new kernel but wasn't sure if the mainstream distro came that way
07:42 PM jepler[m]: a debian realtime kernel for arm64 is apparently available back as far as stretch (via backports)!. but not from raspbian afaik
07:43 PM seb_kuzminsky: dang, that's almost good enough for software stepping, if you're not in a hurry
07:43 PM jepler[m]: hah. it has gone up to 65us.
07:44 PM seb_kuzminsky: i sure have some conflicting emotions about all this leaving old distros and RTAI behind
07:44 PM Tom_L: sad for old hardware yes
07:47 PM jepler[m]: the great news is the old linuxcnc will still run just as well forever
07:49 PM Tom_L: ironic i run wheezy on my mill but buster will run fine on a rpi4
07:49 PM Tom_L: it will run until the hardware dies :/
07:51 PM jepler[m]: I think I'll toss this on a pi400 and hook it up to a display next, figure out the accelerated opengl situation.
07:52 PM jepler[m]: though https://wiki.debian.org/RaspberryPi4#Accelerated_3D_graphics_on_Debian says you have to build a kernel. now I am sad.
