Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

I want to try out the BFS, but am unsure about which architectures I have.

$ cat /proc/cpuinfo
processor	: 0
vendor_id	: GenuineIntel
cpu family	: 6
model		: 23
model name	: Pentium(R) Dual-Core CPU       T4200  @ 2.00GHz

It is listed as an "Intel® Pentium® Mobile Processor" on intel's site.
After searching I still do not know whether I should install ck-pentm, ck-p4 or ck-core2.
I do know that I can compile with -march=native, but prefer to just install from a repo.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@berz_ - you can't go wrong the generic packages.  (ck-generic)

Or just see what the following returns and use that package.

$ gcc -c -Q -march=native --help=target|grep march

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

Hi,

the latest upgrade fails because of broadcom-wl-ck-core2 package in the ck repo contains a file (/etc/modprobe.d/broadcom-wl.conf) that the other broadcom-wl package (in AUR, for the -arch kernel) also provides.

The obvious solution is to add broadcom-wl to confilcts=() array in the PKGBUILD but then wireless connetion will only be available with the -ck kernel and not with the stock kernel, which is not really ideal.

I suggest renaming the file in the package to broadcom-wl-ck.conf, I think two files with the same blacklist won't cause any trouble.


Any better ideas?

This is the exact approach taken with the nvidia-ck(-*)-packages, so no, it should be just fine I think.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@ijanos - Great idea and thanks for pointing it out.  Fixed in 5.100.82.112-1 which just posted to the AUR and repo.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

Had a quick question for anyone else using the linux-ck-pentm package from graysky's repo.

Every...maybe 5 min or so I get a couple of seconds of system hang.  It's really noticeable when playing music because it just stops for a couple of seconds and then continues.  Is anyone else having this problem?  (linux-ck-pentm 3.0.7-1)  And...more importantly, does anyone know how to fix it?

Thanks!

@jazzp - does this happen with the ck-generic package?

@graysky,

Haven't tried that yet...I'll install it and see what happens.  Btw, seriously quick response!

UPDATE:  Yeah, it does the same thing with the generic package.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

If you build it from the AUR, does it do the same thing?  If so, and if the Arch kernel does not cause this effect, I would think there is some regression within the ck1 patchset and your specific hardware.  In that case, I'd post it on CK's blog to see what he thinks.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

I'll try building from the AUR...I'll let you know how it works in a few hours.  There definitely might be a regression concerning my hardware...it's a Sony VAIO...they're a real pain.  Thanks for your help graysky!

UPDATE:  Just compiled and installed linux-ck from the AUR...same problem.  Time to do some debugging!

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

(I posted this somewhere else some time ago, but had not noticed this thread.)

Does the ck package has anything to do with bash's history search and yank-last-arg?

I have this in my .inputrc:

$if mode=vi
    set keymap vi-command
    # these are for vi-command mode
    "\ek": history-search-backward
    "\ej": history-search-forward
    "\e.": yank-last-arg
    set keymap vi-insert
    # these are for vi-insert mode
    "\ek": history-search-backward
    "\ej": history-search-forward
    "\e.": yank-last-arg
$endif

This has been working for ages and still works when I boot the standard 3.0.x kernel. But when I boot the 3.0.x ck kernel, alt+j and alt+k become previous-history and next-history respectively, while alt+. becomes something totally weird (seems like it is pasting parts of the current line).

I see this happening on both of my two machines (ck-corei7-avx and ck-pentm).

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@JazzplayerL9 - I thought that would be the case as the ck-generic packages are theoretically identical to the one you would build from the AUR.
@Markus0000- That's an interesting observation.  The PKGBUILDs are nearly identical to the one in the AUR.  There should be *no* modifications to files not owned by the PKG itself.  What happens if you build the kernel from the AUR tarball?

Thanks!

I get it sometimes when I run terminal tasks, such as compiling or pacman upgrades.

I am using the linux-ck-corei7.

In fact it happened just now when I ran "pacman -Qs linux-ck" to check which package I use. Didn't when I ran it again. It's been consistent ever since the Brain Fuck Scheduler started working for me (I first installed and used it just after linux 3 kernel came out and the patchset hadn't been updated).

So it's definitely something to do with scheduler.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

With ck I have rather sudden feature smile When the system is heavy loaded by multithread applications,

- top shows, say, 260-280% of CPU load (and it is normal for some used benchmarking test and 4-core CPU using, i5 760 at my case),
- qps and KSysGuard (process table) can show anything starting from, say, 10% till 100% of expected load,
- KSysGuard CPU load graph doesn't show any 'system' load, just - sometimes - 'user' only (but must as far as it is the same test I use under official kernel when all load indicators are consistent).

I have linux-ck-corei7 from the repo-ck. The issue doesn't depend on I/O scheduler in use (and it is expected).

Where to dig in further?
Can anybody reproduce the issue?

Building from AUR does break these bindings, too.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@student - no idea what you're talking about smile  What does htop show under load?
@Markus - that suggests whatever is going on to be caused by the upstream patches ... somehow.  Suggest you contact ck either on his blog or by email.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@graysky

'top' shows ~300% CPU load as expected for four cores.
'htop' shows jumping values in ~25-100% range.

No. 'top' is the only showing something related to reality. 'htop' is also affected:

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@student - I never noticed this before.  When I am building a package for example, and look at htop, I don't see cc taking up the cpu cycles.... is this what you are describing?

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@graysky

OK, I'll try to prepare reproducible form official repo test case. I mean at constant durable multithreaded CPU loading test case htop (as well as qps and KSysGuard) shows almost arbitrary jumping values.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@student - can you open a new thread to keep this one on topic: related to packages and repo.  The issue you're describing is interesting, but not truly related.  To your other question about the picture, just do a google image search.  The avatar appeared on the covers of two of Disturbed's albums, Ten Thousand Fists and Indestructible.
