Oof, now I'm tempted to pick up one of those 8BitDo Pro 2 wired controllers that I know I don't really need...

Building 6.3.0 with "bindeb-pkg" after 6.2.12 required installing debhelper package first. Also dpkg building script is modified and CONFIG_LOCALVERSION variable is not appended to .deb package filename anymore. But "uname -a" still includes the variable in the version string of kernel. Other than these Debian specific details, kernel just boots and runs fine for me.

I used to use make deb-pkg but its not working for me, complains it's not a git repo. How does bindeb-pkg differ?

No idea why they made such changes, was fine for years as it was.

I seem to be getting some nasty performance regressions. Having ~40 tabs open (don't judge me…) in luakit slows the entire system to a crawl. Anyone else getting anything like that?

Theodore Tso was not happy about it either.

bindeb-pkg only builds binary packages. deb-pkg does source as well. bindeb is faster.

I would just clone again at https://git.kernel.org/pub/scm/linux...ble/linux.git/

Hello,

Can confirm bindeb-pkg works. It seems this option does the same thing as deb-pkg but doesn't pack up the source folder which as you pointed out is faster.

Thanks

Turns out the system slowdown was coming from a ton of coredumps being generated due to ~40 instances of luajit (on which luakit depends) running out of memory. The root cause was luajit being compiled without the GC64 option, meaning its memory allocation was restricted to 32-bit address space. I don't understand why upgrading to Linux 6.3 made the situation so much worse though…
