Yes, a program published without a license, automatically is considered having a proprietary license where "all rights are reserved" to author. This happens at least on America, Europa and Asia.

For Copyright to apply, a work is required to be non-trivial and/or have an element of originality about it. I don't think we need worry here.

About a half-decade ago I was using Slackware on an old slow computer with not much memory, and I saw similar:

I also disabled animations and 'effects' and whatnot --- but even so, from time to time the computer would start thrashing and the processor(s) would become 100% busy. One day an idea came to me that perhaps the user software was impeding the kernel. So, I ran

Code:

renice -n 10 -u <my usersname>

This worked well, and after a while I added the command into my user's ".xinitrc" file.

5.14.15 build and running fine with Nvidia 470.82.00

Looks like the patch for setting the default dynamic preempt mode has landed in the kernel tip tree. Unless I am mistaken that means it will eventually make its way into the kernel.

Yes, BUT this looks like that it will be added on the kernel 5.16.x so, those will want it in previous versions, they should backport it.

So, did you see our BDFL backporting this patch to 5.14.x or 5.15.x, when he invented that one-liner sed command which basicaly do a similar job at build time ?

Yeah the default preempt=full issue is easily worked around. I am just noting that it looks like they did listen to people complaining about the lack of a changeable default option and fixed it.

Code:

[    0.030953] Kernel command line: BOOT_IMAGE=dev000:\EFI\Linux\slackware/vmlinuz  acpi_backlight=video           rootfstype=ext4           noautogroup preempt=voluntary           fbcon=font:TER16x32           vt.default_utf8=1           loglevel=2 console=tty8 ro
[    0.031767] Dynamic Preempt: voluntary
[    0.031817] Unknown command line parameters: BOOT_IMAGE=dev000:\EFI\Linux\slackware/vmlinuz preempt=voluntary

Looks like they forgot to tell the cmdline parser that preempt= is a thing now.

Yes, this is the salient part:

Quote:

This assumes the parameters are processed in a normal fashion, some parameters (dyndbg= for example) don't register their parameter with the rest of the kernel's parameters, and therefore always show up in this list (and are also given to init - like the rest of this list).

Seems kinda sloppy to allow that though.

Aeterna · 10-28-2021, 10:45 PM

I wonder why not to compile preemptible kernel with full preempt for desktop?
Then other options can be tweaked e.g. RCU, hugepage and so on and so for

plus all GCC tweaks can also help with the performance.

I never had problems with stuttering even under load but I never used default Slackware kernel.

Is there no headers package for 5.14.15?! :O

5.15.0

The newest Stable kernel, version 5.15.0, has been released.

The tarball, https://cdn.kernel.org/pub/linux/ker...ux-5.15.tar.xz

Mr. Torvalds' announcement, http://lkml.iu.edu/hypermail/linux/k...0.3/07730.html

Edit in: Built and installed and it still presents a blank screen for seven seconds after the BIOS check. Other than that, so far, so good.
