Zaurus - Void Linux support / Re: who is working on the Zaurus Kernel?

p.s.
wrote a nice tool to automagically get stuff from an internet url, even recursively

Code: [Select]

macmini2-intel irc # echo "https://logs.nslu2-linux.org/livelogs/kexecboot/" > url
macmini2-intel irc # myNET-get-files-from-url url

thanks!

I am working on a low level bootloader, plus kernel stuff.
Need info, I can't find around.

I will wget and search into logs

Hi, the only developer working on the kernel that I'm aware of is greguu. I don't think there's any active mailing list for Zaurus kernel development, OESF is the only place I know with discussions about it. In the #kexecboot IRC channel on Freenode there used to be lots of useful, although unsorted, info about recent kernel development, there's a log of the channel available here:

https://logs.nslu2-linux.org/livelogs/kexecboot/

I'd suggest to wget those logs and to make local searches there. There were also #alarmz and #voidz channels, though no logs of them are available. Plus the historical #zaurus one for older discussions, logs are here:

Astro Slide - Hardware / Re: changed my battery now with video

« Last post by slide on May 03, 2025, 07:35:34 am »

BTW, the Astro Slide forgets the "data used" value when the battery is disconnected. Perhaps that value is stored in battery-backed RAM which could explain the battery drain I'm experiencing with the Astro Slide being turned off (see https://www.oesf.org/forum/index.php?topic=36948.0).

Sorry, no pics as I thought that Astro Slide was my only working camera (I forgot about my second Astro Slide). Perhaps next time, for the other device.

Much appreciated, I hope you can at some point get pics from the second device!

Zaurus - Arch Linux ARM support / Re: Update: C1000 / Akita support

« Last post by DiTBho on May 02, 2025, 02:03:51 pm »

Another thing: I know Xscale can "scale" the CPU frequency.
Can the Linux Kernel reduce the clock frequency at run-time?
It is useful to extend the battery usage time

if I use the PDA to write with { GNU/Nano, VIM, ... }
I do not need 400Mhz, I can very well work at 200Mhz

I would like to comment on the lines of kernel code that activate the suspension when the power/on button is pressed.

macmini2-intel kernel-5.4.229-arm-akita #

that's how I compile kernels for all the platforms I support, mainly MIPS, POWERPC and HPPA2.
I wrote a "builder" in bash-scripting + C/89, to help managing patches, configuration, and checks

Every build comes with a "profile", which tells about

• the toolchain, with constraints on the min and max versions of binutils and gcc
• the ecosystem (it's called "qualified machines", can also be a chroot, or a container), to ensure you are using the right setup, at least "tested"
• the final size of the kernel
• the final file-format { uboot, elf, bin, zImage, ... }
• etc...

Code: [Select]

checking .config ... success

Here, it checks a file in ensures that the .config contains options considered "essential", and that it does not contain options considered "to be avoided"
