To enable this feature:

Code:

With CONFIG_ZRAM_WRITEBACK, zram can write idle/incompressible page to backing storage
rather than keeping it in memory. To use the feature, admin should set up backing device via:

echo /dev/sda5 > /sys/block/zramX/backing_dev

Is it possible to set :

Code:

CONFIG_ZRAM_WRITEBACK=y

in the kernel ?

@ marav: previous answer here. This being said I have enabled this in a Slint kernel with no issue, but was too lazy to script something to really use it (and I didn't need to so far). All I can say is that I have shipped swapinzram in Slint since Wednesday 23 December 2020 and nobody complained about it so far. Here and now (laptop mostly idle, Slint64-14.2.1, kernel 5.16.11):

Code:

LANG=C free -h
              total        used        free      shared  buff/cache   available
Mem:          7.7Gi       1.1Gi       2.8Gi       188Mi       3.7Gi       6.1Gi
Swap:          14Gi          0B        14Gi
zramctl 
NAME       ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram1 zstd         13,8G   4K   59B    4K       4 [SWAP]
swapon
NAME       TYPE       SIZE USED  PRIO
/swapfile  file      1024M   0B    10
/dev/zram1 partition 13,8G   0B 32567

I keep a small swap file just in case to help me realize the machine is slowing down so maybe the OOM killer is threatening me but can' t remember it having been used. Anyway, better safe than sorry.

my understanding is, that there is no use(anymore) for better performance to have multiple zram-devices.

There was a use case prior to kernel 3.15, https://wiki.gentoo.org/wiki/Zram

There is a use case if you have a low memory system, with multiple cores, a SD Card housing the kernel, and the OS installed to a SSD. I have noticed a small performance hit where the CPU load is higher by a small margin. That is due to the compression/decompression process. At the same time, I do not hit a wall where my systems are swapping to disk, which is often a larger performance issue. Especially on my lower end systems that have SATA hard disks rather than SSD's.

With that said: If you have a AMD Ryzen thread ripper with a nvme disk and 16GB+ RAM- I agree, zram is not all that useful.

To clarify, i meant to say

So a single zram-swap device has the same performance, and is a lifesaver for my old devices.

rc.cgconfig is not parsing config files from /etc/cgconfig.d as cgconfigparser should do when used with the -L flag.

Can we patch it in this way?

Edit: I'm adding the same for cgclear

Firefox 98.0.1

https://ftp.mozilla.org/pub/firefox/releases/98.0.1/

Release notes :
https://www.mozilla.org/en-US/firefo.../releasenotes/

Changed:

Code:

Yandex and Mail.ru have been removed as optional search providers in the drop-down 
search menu in Firefox.

If you previously installed a customized version of Firefox with Yandex or Mail.ru, 
offered through partner distribution channels, this release removes those customizations, 
including add-ons and default bookmarks. Where applicable, your browser will revert back 
to default settings, as offered by Mozilla. All other releases of Firefox remain unaffected by the change.

Meh. I haven't got time (and really couldn't be bothered) searching for, compiling and learning how to use alternatives. Don't get me wrong... I used to be like you. I'd have a list of things I'd download, compile and install every time I installed the latest Slackware. But then more important things in life came along, and I reconciled myself to the fact that Thunderbird works just as well as Sylpheed... and K3b is pretty bloody good, and very hard to find a complete replacement for. I actually need to use my computer... I haven't got time to waste rebuilding it constantly.

Yeah, well, I'm not exactly running supercomputers here. At the office, I've got an 8th gen Intel NUC i5 running vmware with 7 VMs on top of it... not exactly "resource rich." Aside from the disk space (although it's 2022 man... who, in all honesty, can't afford the 16Gb that a full install takes??) modern KDE is quite light on resource usage. It's sufficiently snappy in a VM... snappier than Windows in fact.

ISC BIND 9.18.1 contains four security fixes, a few feature changes and some bug fixes.

rasp · 03-16-2022, 02:10 PM

clicking an extension in firefox (either from slackware or from their site) gives an empty rectangle and:
segfault at 0 ip 00007f83412db629 sp 00007ffc3f2573d0 error 4 in libc-2.35.so[7f83411bc000+186000]
in dmesg.
extensions are not working at all.

is this known/normal, am I stupid or is libc broken ?
