Good work picking it up. Unfortunately I'm having trouble with Fedora on my Blackbird (won't DHCP through my wifi bridge), so I can't really check it right now, but I've been following the commits as they land.

Thank you so, SO much. I've really not enjoyed using Chromium as a full-featured web browser in Fedora, and this will make a wonderful difference to my quality of life.

That's true. But not too long ago, Pearson donated hardware to another project. It's not that far-fetched.
I'm curious to see if there will even be a Power12. And the Power11 is really just a Power10+.

slightly offtopic, but SolidSilicon website went offline since april 1st, (or earlier). That power 11 announcement for somewhere Q12026 isnt coming.
Pearson is probably busy af, holding what little is left of OpenPower together
There's probably nothing to donate, or even new users, for an almost 10 year old power9 plattform at 5 grand
I saw on youtube in one of those webinars that IBM has transfered Power ISA developement to Bangalore, India. If IBM Usa doesn't care about the OpenPower side of things, then I'm certain that no one in India gives a damn.

Why not ping Pearson?
Maybe he is willing to donate hardware to him.

Applications and Porting / [DEV] JIT support for Firefox
« Last post by tle on April 22, 2026, 10:59:24 pm »
Firstly, all credits go to @ClassicHasClass for his great JIT support work for the v86 Firefox (basically baseline JIT is fully working). He had submitted the patches against upstream at https://bugzilla.mozilla.org/show_bug.cgi?id=1860412 but unfortunately the patch has become stale and no longer work with post-140ESR codebase.

So after spending 3 weeks with help from few people in the PPC community and help of AI agents to track down errors pattern (lacking of tooling like rr-debugger made the work super hard - at one stage I was resolving to all sort of blind hypothesis and nearly gave up), I have successfully revived and fixed number of bugs of the original JIT codes. Please check out https://github.com/runlevel5/firefox/pull/1 to all members here for reviewing.

TL;DR; LE path for POWER8, POWER9 and POWER10 is fully implemented (including ION JIT, WASM SIMD, JSPI and Simulator). The BE path and POWER10 optimization are still in progress atm. Please give JIT work a go and let me know if you happen to find any bug. I have tried my best to hand test and ran many stress test / benchmarks and have addressed quite a number of edge cases.

So what's next? Trying to get it polished as much as possible then get it upstreamed (for release 153 - why? new ESR would be branched off this version) or simply try to get the patch accepted in downstream sources like Fedora, Debian/Ubuntu.

It's painful to convince Mike to review and merge such huge delta of changes to support PPC64 JIT. It's understandable taking into consideration and assumption that Mike does not own a POWER8/9 hardware.

I think I could try to review one of those stale JIT work and get it patched downstream in Fedora. If that approach proves successful, I strongly believe Mike would likely give his blessing to the JIT port after few years of real world usage downstream.

PPC64le port is now available: https://obdev.at/products/littlesnitch-linux/download.html, direct link: https://obdev.at/downloads/littlesnitch-linux/littlesnitch_1.0.3_ppc64el.deb

I haven't been able to get it to work. On Debian 13 with kernel 6.12.74, I'm getting an bpf error:
Apr 20 20:08:32 behemoth littlesnitch[28597]: Error: `bpf_raw_tracepoint_open` failed

I use it for OS X, and it is a fine product, but in reality it has limited usefulness due to the consolidation on cloud computing and the control of the Internet by Google.  It is not possible to limit connections to miscreant sites without blocking legitimate ones, if they share the same ip address(es) or blocks, as is common with cloud computing.  It is not possible to block Google without breaking some or all functionality of perhaps 90% of web sites, since so many sites rely on Google APIs for the creating of their sites.

You can block some of Google and on a per-app basis, which is what's cool about Little Snitch.
