Intel posts a new "Xe" graphics driver

2 év 7 hónap óta
Intel's graphical processors have been well supported in the mainline for years, but it seems that the i915 driver may be approaching the end of its development life. Matthew Brost has just posted a new driver called "Xe" that looks to be (eventually) a replacement for i915:

The intention of this new driver is to have a fresh base to work from that is unencumbered by older platforms, whilst also taking the opportunity to rearchitect our driver to increase sharing across the drm subsystem, both leveraging and allowing us to contribute more towards other shared components like TTM and drm/scheduler.

[$] Not coalescing around None-aware

2 év 8 hónap óta
The wish for a "None-aware" operator (or operators) is longstanding within the Python community. While there is fairly widespread interest in more easily handling situations where a value needs to be tested for being None before being further processed, there is much less agreement on how to "spell" such an operator (or construct) and on whether the language truly needs it. But the idea never seems to go away, with long discussions erupting every year or two—and no resolution really in sight.

Ryabitsev: Sending a kernel patch with b4 (part 1)

2 év 8 hónap óta
Konstantin Ryabitsev has put up a blog entry showing how to use b4 to submit kernel patches without (directly) using email.

While b4 started out as a way for maintainers to retrieve patches from mailing lists, it also has contributor-oriented features. Starting with version 0.10 b4 can:

  • create and manage patch series and cover letters
  • track and auto-reroll series revisions
  • display range-diffs between revisions
  • apply trailers received from reviewers and maintainers
  • submit patches without needing a valid SMTP gateway

Second Prototype Advances ALP (openSUSE News)

2 év 8 hónap óta
The openSUSE News site covers some highlights from the second prototype release of the upcoming SUSE "ALP" distribution.

The mountainous prototype has the big addition of Full Disk Encryption. ALP extended this Full Disk Encryption to bare metal servers and the use of a Trusted Platform Module will open the doors to leverage unattended booting while keeping systems encrypted and secured. ALP is intended to run on both private and public clouds that require encryption features.

[$] Wrapping up 2022

2 év 8 hónap óta
Yet another year is coming to a close; that can only mean that the time has come to indulge in a longstanding LWN tradition: looking back at the predictions we made in January and giving them the mocking that they richly deserve. Read on to see how those predictions went, what was missed, and a look back at the year in general.

Huang: Towards a More Open Secure Element Chip

2 év 8 hónap óta
Andrew 'bunnie' Huang writes about his work with Cramium to bring more openness to secure element chips:

In my view it’s better to compromise and have a seat at the table now, than to walk away from negotiations and simply cede green fields to proprietary technologies, hoping to retake lost ground only after the community has achieved consensus around a robust full-stack open source SE solution. So, instead of investing time arguing over politics before any work is done, I’m choosing to invest time building validation test suites. Once I have a solid suite of tests in hand, I’ll have a much stronger position to argue for the removal of any proprietary CPU cores.

Régen javított sérülékenységek aktív kihasználására figyelmeztet a Cisco

2 év 8 hónap óta

A Cisco számos régebbi biztonsági figyelmeztetést frissített, ugyanis a hálózati eszközeiket érintő kritikus és magas besorolású – akár már 4-5 évvel ezelőtt orvosolt – sérülékenységek javításai közül sokat máig sem alkalmaztak az érintett szervezetek. Múlt héten a Cisco több mint 20, a Cisco IOS, NX-OS és HyperFlex szoftvereket érintő biztonsági hibák kihasználásával kapcsolatban adott ki […]

[$] Beyond microblogging with ActivityPub

2 év 8 hónap óta
ActivityPub-enabled microblogs are gaining popularity as a replacement for Twitter, but ActivityPub is for more than just microblogging. Many other popular services also have open-source alternatives that speak ActivityPub. Proprietary services operated by commercial interests usually deliberately limit interoperability, but users of any ActivityPub-enabled service should be able to communicate with each other, even if they are using different services. This promise of interoperability is often limited in practice, though; while ActivityPub specifies how multiple types of content can be published, the kinds of content that can be displayed or interacted with vary from project to project.

520 millió dolláros pénzbírságot kapott az Epic Games

2 év 8 hónap óta

Az Egyesült Államok Szövetségi Kereskedelmi Bizottsága (FTC) rekord összegű pénzbírságot szabott ki a Fortnite kiadójára, mert megsértették a gyermekek online adatvédelméről szóló törvényt (Children’s Online Privacy Protection Act, COPPA) és megtévesztéssel játékon belüli vásárlásokra vették rá a felhasználókat.

Dave Airlie (blogspot): vulkan video decoding: radv status

2 év 8 hónap óta

I've been working the past couple of weeks with an ffmpeg developer (Lynne) doing Vulkan video decode bringup on radv.

The current status of this work is in a branch[1]. This work is all against the current EXT decode beta extensions in the spec.

Khronos has released the final specs for these extensions. This work is rebased onto the final KHR form and is in a merge request for radv[2].

This contains an initial implementation of H264 and H265 decoding for AMD GPUs from TONGA to NAVI2x. It passes the basic conformance tests but fails some of the more complicated ones, but it has decoded the streams we've been throwing at it using ffmpeg.

Building:

git clone https://gitlab.freedesktop.org/airlied/mesa

git checkout radv-vulkan-video-prelim-decode

mkdir build

meson build -Dvulkan-beta=true -Dvulkan-drivers=amd -Dvideo-codecs=h264dec,h265dec --prefix=<prefix>

cd build

ninja

ninja install

Running:

export VK_ICD_FILENAMES=<prefix>/share/vulkan/icd.d/radeon_icd.x86_64.json
 

For prelim branch[1]:

export RADV_VIDEO_DECODE=1

For merge branch[2]:

export RADV_PERFTEST=video_decode

vulkaninfo

This should show support for VK_KHR_video_queue, VK_KHR_video_decode_queue, VK_EXT_video_decode_h264 and VK_EXT_video_decode_h265.
