The project targets kernel patches and the q6voiced userspace daemon used to enable call audio on Linux mobile devices, reducing reliance on kernel forks and lowering maintenance burden. ### Source excerpt As we have mentioned in the 2026 financial budget, we are able to follow up last year's success of financing important audio improvements in postmarketOS and the wider Linux Mobile ecosystem with another project this year! This time we will tackle the currently unupstreamable q6voice patches that every kernel fork for Qualcomm devices has to carry in order to be able to do audio calls. This is one of the last pieces of technical debt that hold back most devices from using a pure mainline kernel without additional patches, which would in turn lower the maintenance burden significantly, make call audio more reliable and would make it easier for other Linux distributions to run on these devices as well. The proof of concept It was early 2020, not even three years had passed after postmarketOS was published, and most people reading this probably had not heard of the project yet. At that time, Minecrell and Nikita were very busy maintaining and bringing up the MSM8916 family of devices. In the process, they achieved a considerable milestone: they managed to get calls (!907) and call audio (!1228, !1233) working on mainline for devices released with Android. This, for the first time, allowed those devices to be used as actual phones! Specifically for enabling call audio, Minecrell wrote two distinct pieces of software: The q6voice kernel driver: first included in a release of the msm8916 close-to-mainline kernel, it talks to the modem, and configures it so the audio that is being received from the cellular tower can be consumed in software. The q6voiced user-space daemon talks to the kernel to start or stop the audio streams so one can hear the other person on the other side of the call. Although an extraordinary achievement, the implementation was considered a workaround by the authors. From the initial commit: Eventually this should go away by implementing codec2codec support for q6voice in the kernel. In that case, the stream would be started once the audio routes are ## OpenCL Cooperative Matrix Extensions Are Here DevFeed: [OpenCL Cooperative Matrix Extensions Are Here]() Original publisher: [Read original article]() Author: jphilips (jeff@khronosgroup.org) Published: 2026-04-29T13:00:00Z Content type: release Language: en Sources: [Blogs Khronos Blog]() Topics: [AI Inference](), [GPU](), [C](), [LLVM](), [GitHub]() Tags: [api](), [arm](), [blog-opencl-spirv-machinelearning-llv](), [c](), [gpu](), [intel](), [llvm](), [opencl](), [qualcomm](), [spir](), [vulkan]() ### AI overview The OpenCL Working Group has published a working draft of the cl_khr_cooperative_matrix extension, developed with Arm, Intel, and Qualcomm.

The issue involves audio-server selection and Pipewire-related problems; an upgrade or Pulseaudio package change may resolve it depending on the installation. ### Source excerpt Unfortunately, despite a lot of testing previous to the v25.12 release, a combination of several bugs with similar symptoms resulted in non-functional audio by default for some Qualcomm devices when specifically installing systemd and GNOME/Phosh (more specifically gnome-settings-daemon, which is a core part of the desktop). If you are using a device with a Qualcomm chip, are in edge or stable, have a recent install of systemd with GNOME, and experience very low audio, you might be able to fix the issue by running the following command: doas apk add postmarketos-base-ui-audio-pulseaudio In case that does not fix your issues, you can come back to the previous status by running doas apk del postmarketos-base-ui-audio-pulseaudio EDIT: We merged !7776, which obsoletes the steps mentioned for postmarketOS edge, you just need to run doas apk upgrade -Ua. We're still waiting a testing period before we merge this for the stable release v25.12 as well. (!7783) Root causes Some Qualcomm devices have had issues with volume under Pipewire due to audio formats for a while. There is a workaround available in postmarketOS, but it is not applied consistently to all devices. This should not have been a big deal, since in principle we are not using Pipewire's audio server by default. However, there is also an issue affecting the default choice of audio server between pipewire-pulse and pulseaudio on new installs. For some reasons that we have not yet fully understood, the combination of systemd and gnome-settings-daemon results in pipewire-pulse being installed, even when pulseaudio is expected. Progress is being tracked in !7776. We also cannot discard further issues with Pipewire's audio server, as that is not yet extensively tested on mobile. The day we change the default, we will provide a notice and make sure that more testing is executed. Hopefully the hardware CI work can help with this in the future. We apologize for the inconvenience this has caused, specially since this iss ## exploits.club Weekly(ish) Newsletter 92 - S23 N-Day PoCs, Printer Overflows, DNG OOB Writes, And More DevFeed: [exploits.club Weekly(ish) Newsletter 92 - S23 N-Day PoCs, Printer Overflows, DNG OOB Writes, And More]() Original publisher: [Read original article]() Author: exploits.club Published: 2025-11-21T16:10:47Z Content type: article Language: en Sources: [exploits.club]() Topics: [Hacking](), [Exploit](), [Security](), [Vulnerabilities](), [Linux](), [Kernel](), [GPU](), [Qualcomm](), [samsung](), [Android](), [ctf](), [Advent of Code]() Tags: [android](), [code](), [ctf](), [exploits](), [gpu](), [hacking](), [kernel](), [linux](), [newsletter](), [printer](), [qualcomm](), [samsung]() ### AI overview The 92nd exploits.club Weekly(ish) Newsletter rounds up recent developer and security content, including Advent-themed CTFs, Advent of Code 2025, Binary Ninja 5.2, conference slides, an exploit for Qualcomm GPU microcode vulnerability CVE-2025-21479 on a Samsung S23, Linux KASLR research, and printer security flaws. ### Source excerpt We are so back.

It discusses QMI services and transports, limitations of Qualcomm Diag tooling, and using Frida to capture QMI messages from a running process. ### Source excerpt This is a guest blog post by Alexander 'lynxis' Couzens, one of the people behind the OpenIMSd NLnet project funded by NGI Zero Core. At postmarketOS we helped them create a grant proposal, and continue helping with project planning. For more details, check the project website. We thank NLnet and the NGI Zero Core fund for supporting this initiative. Introduction To investigate how the Voice over LTE stack in Qualcomm based phones works, I have to look into the QMI interface. QMI is a structured interface using TLV. Furthermore, QMI is a protocol which can be used over different interface and offers communication between services. A service usually handles a logical component of the baseband, e.g. the communication with the simcard is handled by the UIM (User Identity Module). Or the NAS handles the high level Network Access. QMI also supports multiple clients at the same time. It allows two daemons to communicate via QMI at the same time without the need to synchronize with each other. QMI supports at least communication over the following transports (not a full list): USB (e.g. mini-pcie) Shared memory (SoC) Socket (kernel socket class, but internally over shared memory) Tunneled over Qualcomm Diag To research the QMI VoLTE messages of a stock Android, we need to able to capture those messages. When I first encountered QMI and researched how the "legacy" voice calls are working on Qualcomm based phones, I used Qualcomm Diag for it using the osmo-qcdiag project. Sadly osmo-qcdiag only supports Qualcomm Diag when exposed as TTY on Linux via /dev/ttyXXXX, but not (as many other projects by now) directly via USB without a kernel driver. The issue with the kernel driver is the limited support of devices. When enabling Qualcomm Diag for a new phone, it requires a small patch to add the USB ID to the driver. Other projects like SCAT or QCSuper can use libusb to directly communicate with the phone. Because of this I tried to add QMI sniffing in SCAT, but it didn't work wi ## postmarketOS in 2024-11: pmbootstrap v3, RFC process and Seattle DevFeed: [postmarketOS in 2024-11: pmbootstrap v3, RFC process and Seattle]() Original publisher: [Read original article]() Published: 2024-12-09T00:00:00Z Content type: article Language: en Sources: [postmarketOS Blog]() Topics: [Linux](), [Mobile](), [Maintainers](), [GitLab](), [Bluetooth](), [middleware](), [kernels](), [patches](), [SOC](), [bug](), [Pipewire](), [dell]() Tags: [bluetooth](), [bug](), [conference](), [developers](), [gitlab](), [kernels](), [linux](), [maintainers](), [middleware](), [mobile](), [postmarketos](), [qualcomm](), [us]() ### AI overview A postmarketOS community update covering its SeaGL conference presence, new Trusted Contributors, Linux mobile development work, and the migration to a self-hosted GitLab instance with stability and CI issues. ### Source excerpt Anjan, Arnav and Clayton represented postmarketOS at the SeaGL conference with a stand, where they showed off several devices running postmarketOS (OP6, PinePhone, Surface RT, some Dell tablet among others) and talked with many attendees. Anjan also gave an excellent talk, Introduction to postmarketOS. The beautiful table cloth was designed by Ranny. Here is Arnav describing the stand experience: People were generally impressed by OP6 performance and GNOME Mobile snazziness. Some people were Linux-savvy and were there on purpose, but it seems more than a few people just roamed in wondering what the crowd was about, so it was nice to see their eyes light up when we described pmOS to them. Some of them even realized by themselves without us telling them that this would allow them to reuse their old phones for something useful, which was amazing. Organizational Trusted Contributors We have three new Trusted Contributors this month, who we are really excited about! Anjan: One of the maintainers of our favorite tiling WM based Linux Mobile interface Sxmo. He also maintains quite a few Alpine Linux packages and contributed some cool pmbootstrap patches! Barnabás: Maintains multiple Qualcomm SoC kernels in pmOS, as well as related device ports and does important mainlining work! Dylan: Works on VoLTE, Bluetooth HFP, Qualcomm sensors, helps with improving community and main devices like the Fairphone 4/5 and SDM845 devices as well as middleware such as PipeWire, fwupd and ModemManager. Dylan isn't new to the team, but he has switched from Core Contributor to Trusted Contributor to have a lower time commitment regarding organizational stuff.

As shown in the photo above, they had a cool table with asus-grouper, asus-tf201, xiaomi-beryllium, pine64-pinephone as well as stickers and flyers in Japanese (which ran out by the end!) and English. Several visitors mentioned that they were astonished how fast the tf201 and grouper appeared in the shell - and in general they were interested in seeing devices running with (near) mainline kernels. Thanks to everybody who came by! If you are in the area and missed the event, a Spring edition is coming up in February 2025. Organizational NLnet Grants Accepted Pablo and Oliver helped members of the Linux Mobile community to apply for grants from NLnet's NGI Zero Core fund, and we are excited to announce that they have been accepted! Biktor and Lynxis will be working on OpenIMSd, which aims to bring VoLTE (4G voice calls) to Qualcomm based phones (like the PinePhone) running Free Software Mobile Operating Systems including postmarketOS, Mobian and others. They will create a daemon which runs in parallel to ModemManager, which configures the baseband via QMI and brings up all the required services to be able to place VoLTE calls. Danny will be able to improve mobile-config-firefox and replace hacks we currently carry there to make the desktop version of Firefox work on mobile, with proper solutions in upstream Firefox. See Enhancing Firefox for Linux on Mobile for details. Milestones have been created and will be filled with related issues and merge requests. Trusted Contributors Aster is a new Trusted Contributor! They have been contributing to postmarketOS a lot over the past months, especially the Lomiri packaging, systemd support and design ideas for optionally immutable postmarketOS. Bryant stepped down as TC, and we thank him for the great improvements he has made to the project in the short time as TC: a lot of hel ## Why Meta's Llama 3.1 405B Matters for Open-Source AI DevFeed: [Why Meta's Llama 3.1 405B Matters for Open-Source AI]() Original publisher: [Read original article]() Published: 2024-07-23T00:00:00Z Content type: opinion Language: en Sources: [Tim Kellogg]() Topics: [llama](), [Artificial Intelligence](), [Open Source](), [Open Source Models & Datasets](), [Meta](), [Large Language Model]() Tags: [ai](), [ai-inference](), [ai-models](), [hardware](), [llama](), [meta](), [open-source](), [open-source-ai](), [qualcomm]() ### AI overview This opinion article argues that Meta's Llama 3.1 405B is significant because it brings a frontier-quality open-source model to developers and companies.

It updates Sxmo and Tweaks, improves modem and GPU support for some devices, fixes hotspot functionality with the firewall enabled, and adds optional GTK 3 and GTK 4 themes. ### Source excerpt New month, new service pack! As always, new features and fixes have been backported from postmarketOS edge to the stable version after tough testing by our tough community members on edge. Overview Sxmo 1.5.2: as usually we've coordinated with the Sxmo team on what should be in the service pack, and thanks to them, got Sxmo 1.5.2 in. This is the tried and tested 1.5.1 version from edge, with just minor extra fixes on top. Tweaks 0.8.1 has a new sound panel, better notch support, some bugfixes for the background daemon and fixed touch navigation on the mobile layout. linux-postmarketos-qcom-sdm845 5.14 improves the OnePlus 6 and 6T ports: among other improvements it ships initial modem support and more GPU performance. ModemManager 1.18.2 was required for modem support in the SDM845 kernel. As nice benefit it should improve call and SMS handling. NetworkManager 1.32.10 was backported to fix hotspot functionality while having the firewall enabled. postmarketos-theme can now be installed to get GTK 3 and GTK 4 postmarketOS themes (see photo). Details ModemManager This release backports the calling stack from edge. The new release of ModemManager brings a lot of improvements for the devices supported in community and will help a lot with the stability of the modem when the PinePhone awakes from deep sleep. This release also adds support for the modem in Qualcomm Snapdragon 845 devices. The full calling functionality on those devices is not working yet but it means that at least mobile data and SMS is usable. postmarketos-theme This release also includes the new postmarketOS theme as an optional package. This currently contains a GTK 3 and GTK 4 theme which is based on Adwaita but replaces the standard blue highlights in the theme with postmarketOS green. There's also the oled and paper variant of the theme that are completely black and completely white. This will mainly look great on oled displays, as the name suggests. It's possible to try this on your own device now b ## April 2020 round-up DevFeed: [April 2020 round-up]() Original publisher: [Read original article]() Author: Samuel Dionne-Riel Published: 2020-05-06T00:00:00Z Content type: news Language: en Sources: [Mobile NixOS news]() Topics: [Linux](), [Linux Kernel](), [Wi-Fi](), [Qualcomm](), [configuration]() Tags: [configuration](), [kernel](), [linux-kernel](), [mobile](), [qualcomm](), [series](), [updates](), [wi-fi]() ### AI overview The April 2020 Mobile NixOS project update reports 11 merged pull requests, including device-specific documentation, a supported way to include device configuration, WCNSS WLAN support for one Qualcomm-based device, an initrd configuration change, LED control during boot, and Linux kernel cleanup patches. ### Source excerpt This update is the sixth in a series of regular updates on the state of the project. Only changes that have been accepted and merged in Mobile NixOS are chronicled here. There's always more work currently in-progress. Notable changes 11 PRs were merged during the month. Not an exciting month with fun and visible progress, but let's point out interesting changes Device specific website pages The Devices List section is now formatted as a table, and links to one page per device. This page can contain device-specific notes, and generally contains generic instructions depending on the device type. The side-bar uses generated content, but the page will use the README.adoc file when found in the device directory. All of this is part of PR #120. Supported way to include from system configuration In PR #123 a supported way to include a device configuration to the system configuration was added. The Getting Started page explains the details. This is useful when combined with the next higlighted changes. The device specific configuration doesn't have to be handled by the end-user, the Mobile NixOS configuration handles it. WCNSS WLAN quirk PR #126 adds support for WCNSS WLAN in Mobile NixOS, while enabling it for the only device that supports it. This is the simplest Wi-Fi setup for Qualcomm-based hardware. Sadly, for other devices it's much more involved. Though, this does mean that we now have Wi-Fi support for one more device! Bonus change: Buried in that same PR, we now use boot.initrd.enable = false rather than using isContainer. This fixes a couple of weird and annoying issues with the running system. Device-specific polishing PR #126 PR #128 These start implementing some polishing, in what I hope becomes the gold standard for device ports. First, we configure the LEDs so the Linux kernel controls it during boot (z00t, oneplus3). This provides a tangible proof to the end-user that the kernel is currently in control and running. Then, for asus-z00t, some kernel cleanup p ## Android CPU, Compilers, D8 & R8 DevFeed: [Android CPU, Compilers, D8 & R8]() Original publisher: [Read original article]() Author: Yonatan (Yoni) Levin Published: 2019-03-18T06:27:24Z Content type: tutorial Language: en Sources: [Stories by Yonatan V.

It also discusses CPU architectures and the challenges of compiling native code for different devices. ### Source excerpt Imagine you have an important space mission ahead. You need a spacecraft that won't get you into much trouble on the way. You may opt in a regular YT-1300 freighter. It's popular and you know the basics of its operation. However, you've always dreamed of maneuvering like a pro. You are ready to practice a lot and learn various stuff. Millenium Falcon is what you actually want. But this upgraded spaceship will require that you master it like Han Solo! Lately, I've been inspired by the Google effort to improve compilers, such as the development of R8 or speeding up the Gradle builds. So I guess this is the right time to dig in and talk to you about those improvements. But first, let me guide you through the basics. When you reach the end of this article: You'll know about JVM and its relation to Android. You'll be able to read Bytecode. You'll get an idea of the Android Build System. You'll learn what AOT and JIT stand for and how they are connected to the new R8 compiler. And also a little bit about Star Wars :) So grab a large cup of good coffee, the lightsaber, cookies, and prepare for a read :) CPU & JVM In every device, there is a CPU. It's a tiny thing responsible for every single calculation in your app. In the beginning, the CPU could tackle only with basic math operations such as addition, subtraction, division, and multiplication. Over the years it has evolved into a complex mechanism that can be tailored for specific needs like Image Processing, Audio Decoding with a smart caching mechanism. The most known CPU is Snapdragon by Qualcomm. But there are others. Some of them use the same CPU architecture as Qualcomm, while some don't. And here I say 'Welcome to hell.' If you've ever developed C++/C, you know that your native code should be compiled to every supported CPU architecture: ARM, Arm64, x86, x64, MIPS. As an Android developer, you have to support CPU architectures for all the variety of devices. Basically, this means multiplying your .so files by the ## postmarketOS's First Year and Progress Toward Mainline Phone Support DevFeed: [postmarketOS's First Year and Progress Toward Mainline Phone Support]() Original publisher: [Read original article]() Published: 2018-06-09T00:00:00Z Content type: article Language: en Sources: [postmarketOS Blog]() Topics: [Operating system](), [Linux](), [Linux Kernel](), [Embedded Software Dev](), [Android](), [Qualcomm](), [SOC]() Tags: [android](), [bluetooth](), [contributions](), [firmware](), [kernel](), [linux](), [linux-kernel](), [news](), [postmarketos](), [qualcomm](), [soc](), [technical]() ### AI overview The post reviews postmarketOS after its first public year, describing its goal of providing a sustainable operating system for long-term device use. It covers developer-only status, shared packages across devices, progress toward mainline Linux kernel support, and work on phone audio and modem functionality for Qualcomm-based phones. ### Source excerpt postmarketOS: Experimental Sustainable Operating System Wow, so it has been one full year since the public announcement of postmarketOS, and what a year it has been! During this time the project has grown beyond our wildest dreams; dozens of contributors making a wide variety of contributions, friendships made, bragging rights established (and lost, and re-established), Doom running on things it probably shouldn't, and we're ultimately just getting started. This post is also a celebration of all the hard work that has gone into postmarketOS in the last year, it's first year! Before we begin with our list of changes since the last post in December and other exciting news, a quick intro for folks just now learning of this project for the first time: postmarketOS aims to be a sustainable operating system that empowers users to safely use their devices for as long as possible (ideally until they physically fall apart). The system is designed to share as many packages as possible between supported devices, with the ability to make exceptions for a few device-specific packages as appropriate/needed. This is in contrast to systems like Android, where the many device-specific changes are required to support any particular device. At this point, postmarketOS is only meant to be used by developers. In most instances, phone calls, SMS, bluetooth or the mainline kernel won't work on your device, and there's the firmware problem. Mainline On the Horizon In February 2017 Jeremy McNicoll presented on his progress with forward porting the Google Nexus 5X/6P. He explains the technical difficulties of replacing the downstream Linux kernel that you find on your device after you bought it with the latest upstream version. Towards the end he mentioned on his "lessons learned" slide: "Maybe 10 years ago I would have said we can cure world hunger, we can get the whole thing working." Then he shook his head. "I'm more realistic now." This is how it felt one and a half years ago. It was har
