I wrote up a bash script (Yes!) to do cpu speed control. As a script, it has no external dependancies. The only requirements are that the CPU supports frequency scaling, and that the appropriate CPU governors are compiled into the kernel. -- Walter Dnes I don't run "desktop environments"; I run useful applications

The '-c' parameter doesn't (need to) take either name or category/name so I don't see how this isn't a bug. Getting an ETA average for more than one package and comparing it against the currently merging package makes no sense. Cheers, Arve

It is not a bug. The manpage says it takes name or category/name. In the former case it has to match anything named rust. There are two packages named exactly 'rust': dev-lang/rust and virtual/rust.

That is apparently not the case today. Interesting thoughts. First, cpufreq-set seems to be not available on gentoo anymore. Doesn't matter, just giving it a try. It came out, that all build times have nearly the same sys times but the user and real times vary. Funny, this is a two CPU machine but the build with -j1 consumes the least user time. Just the real value gives the same pattern than on the site.

[gentoo-user] Is this a genlop bug?
Hello list, When I run "genlop -c" is it supposed to include the whole cat/pkg name in its calculations, or just the pkgname? I saw this today: $ genlop -c Currently merging 8 out of 16 * dev-lang/rust-1.29.1 current merge time: 13 minutes and 38 seconds. ETA: 1 minute and 58 seconds. $ genlop -t rust | grep second merge time: 29 minutes and 26 seconds. merge time: 4 seconds. merge time: 10 seconds. merge time: 32 minutes and 44 seconds. $ genlop -t dev-lang/rust | grep second merge time: 29 minutes and 26 seconds. merge time: 32 minutes and 44 seconds. This looks like a bug to me. -- Regards, Peter.
