heftig's nightlies: Firefox, Freetype, and more

How is linux-zen compared to the more popular linux-ck patchset, which also aims for desktop performance/interactivity?

heftig · 2015-07-21 18:49:46

I have made no comparisons against linux-ck.

We've carried BFS in ZEN for a long while but I'm not building with it enabled. It has caused problems in the past and is missing cgroup support. Con is also slow to port it to new kernels, so I won't wait for it.

Liquorix is a rebranding of ZEN providing binary packages for Debian. The code is identical.

Is firefox-developer-edition less protected than arch firefox package?

hardening-check /usr/bin/firefox-developer-edition
/usr/bin/firefox-developer-edition:
Position Independent Executable: yes
Stack protected: yes
Fortify Source functions: no, only unprotected functions found!
Read-only relocations: yes
Immediate binding: no, not found!

hardening-check /usr/bin/firefox
/usr/bin/firefox:
Position Independent Executable: yes
Stack protected: yes
Fortify Source functions: yes (some protected functions found)
Read-only relocations: yes
Immediate binding: no, not found!

Is it normal fortify is not enabled?

Since the update to v42, I am getting some random lockups. Anyone else getting the same issue?

Are you using DRI3? I've seen similar lockups when DRI3 is enabled.

(A shame, since DRI3 is tear-free and butter-smooth and doesn't have the frame rate problems DRI2+TearFree has.)

Right, I just started using it to try to solve crashes with Plasma 5.

Linux-zen is on community, what the difference with you inux-zen?

It's the same package. It was moved.

- Tweaks and fixes to improve usability and interactivity for desktops and laptops

Does this include CONFIG_HZ=1000?

If not, could you possibly add it? It is supposed to improve interactivity for desktops, and is the value used by the Fedora and openSUSE kernels.

heftig · 2015-08-14 09:10:50

It doesn't seem to matter much these days. High resolution timers provide precise wake-ups even without having a frequent interrupt timer, while NO_HZ prevents the timer from running while idling.

- Defaults to YeAH for TCP congestion control

Is there any specific reason for this? All benchmarks I can find on TCP congestion control algorithms seem to show that the default "cubic" is the best.

See the YeAH paper for the conclusions and some comparisons.

I found another paper yesterday which was also talking about YeAH and was showing that cubic was the best, but I can't find it anymore now

heftig · 2015-08-18 01:35:04

YeAH as default was added by Damentz.

Here's another paper that shows how the algorithms react to each other: http://www.satnac.org.za/proceedings/20 … ies/15.pdf

I just benchmarked linux-zen vs linux-bfq (from AUR) and I have a better performance with linux-bfq for some reason.
In TF2 (the test was done twice on both kernel to ensure that the result was correct):
linux-zen 123 FPS
linux-bfq 132 FPS

With compress-7zip in phoronix-test-suite:
linux-zen 17 899 MIPS
linux-bfq 18 457 MIPS

I build linux-bfq with CPU native optimizations and CONFIG_HZ=1000, not sure if these two are making the difference.

heftig · 2015-09-07 17:23:28

I am currently running FDE with these settings, and scrolling is butter-smooth most of the time:

layers.acceleration.force-enabled = true
layers.async-pan-zoom.enabled = true
layers.enable-tiles = true
gfx.canvas.azure.backends = skia,cairo
dom.ipc.processCount = 20
browser.tabs.remote.autostart = true

The critical settings in this case are electrolysis, APZ and tiling.

AnAkkk · 2015-09-23 09:12:55

Since the update to v43, HTML5 youtube videos no longer work for me.

EDIT: Had to set media.fragmented-mp4.gmp.enabled back to false.

Thanks!! This repo is awesome!

With GTK 3.20 there seem to be rendering issues in firefox. GTK 3.20 is currently in the gnome-unstable repo.
The firefox package received a patch to fix these issues:

https://projects.archlinux.org/svntogit … f2a0e722a3

Could you please apply this on your package?

heftig · 2016-03-30 22:06:28

Not before gtk 3.20 lands in extra, sorry.

AnAkkk · 2016-04-09 16:19:15

It has landed in extra now.

Hi heftig, thanks for providing the firefox-dev package. Unfortunately it keeps crashing for me.
Is it just me?

Thanks.

AnAkkk · 2016-05-15 10:43:16

It started crashing for me as well few days ago, I've switched to nightly for now.

beta990 · 2016-05-15 11:13:02

Hi AnAkkk,

Did you compile or installed the bin?

Thanks.

Edit: New version doesn't seem to crash anymore

Hi @heftig,
I was wondering what will be the fate of firefox-developer-edition in your repo now [1]?
