The LWN.net Weekly Edition for October 31, 2024 is available.

We all know how it's possible for a guest VM to access various host functions by accessing a PCI device, right? When KVM traps an access to this fake PCI, QEMU emulates the device, which allows packets sent, console updated, or whatever. This is called "virtio".

NVIDIA took it a step further: they have a real PCI device that emuilates QEMU. No joke. And, they have a firmware bug! The following patch works around it:

diff --git a/drivers/virtio/virtio_pci_modern.c b/drivers/virtio/virtio_pci_modern.c index 9193c30d640a..6bbb34f9b088 100644 --- a/drivers/virtio/virtio_pci_modern.c +++ b/drivers/virtio/virtio_pci_modern.c @@ -438,6 +438,7 @@ static void vp_reset(struct virtio_device *vdev) { struct virtio_pci_device *vp_dev = to_vp_device(vdev); struct virtio_pci_modern_device *mdev = &vp_dev->mdev; + int i; /* 0 status means a reset. */ vp_modern_set_status(mdev, 0); @@ -446,8 +447,16 @@ static void vp_reset(struct virtio_device *vdev) * This will flush out the status write, and flush in device writes, * including MSI-X interrupts, if any. */ - while (vp_modern_get_status(mdev)) + i = 0; + while (vp_modern_get_status(mdev)) { + if (++i >= 10000) { + printk(KERN_INFO + "virtio reset ignoring status 0x%02x\n", + vp_modern_get_status(mdev)); + break; + } msleep(1); + } vp_modern_avq_cleanup(vdev);

I'm not dumping on NVIDIA here at all, I think it's awesome for this devious hardware to exist. And bugs are just a way of life.

Timothée Ravier has written a blog post about changes in the Fedora Atomic Desktops for Fedora Linux 41. Some of the notable new features for Atomic Desktops include bootloader updates enabled by default for UEFI systems, first steps towards using bootable containers, and more.

They pushed the "You're one of a few experts invited to answer" notifications for a long time - maybe a year, I don't remember. When I had enough and started to capture them with the intent of mockery, they stopped. So sad. Here's what I got:

"You're facing pushback from vendors on cloud integration. How can you convince them to collaborate?"

"You're focused on cutting costs in cloud computing. How do you ensure security protocols aren't compromised?"

"You're overseeing a code review process. How do you ensure feedback boosts developer morale?"

What a dystopia. LinkedIn is owned by Microsoft, so I'm not suprised someone in a giant corporation thought this sort of nonsense was a good idea. But still, the future is stupid, and all that.

P.S. The notification inserts were non-persistent — inserted on the fly. That was just fraud w.r.t. the idea of notification ticker.

P.P.S. Does anyone else think that this sort of thing would cause self-selection? They made their AI trained by the most vain and also least bright members of their user population. I'm not an expert in any of these fields.

UPDATE 2024-10-31: Spoke too soon! They hit me with the notificantion insert: "Here's how you can craft a personalized learning plan for advancing in Cloud Computing." That is not even a formed question. Getting lazy, are we?

UPDATE 2024-11-02: "You're facing budget disputes over cloud solutions. How can you align IT and non-technical teams effectively?" They are not stopping.

Meanwhile, how about another perspective: I saw an update that Hubbert Smith contributed an answer to: "You're facing a ransomware attack crisis. How do you convey the severity to a non-technical executive?" Instead of answering what LinkedIn AI asked, he answered a question of how to deal with ransomware ("Ransomware is fixable with snapshots of sensitive data."). Unless he is an AI himself, he may be thinking that he's dealing with a LinkedIn equivalent of Quora.

I'm trying to ask him what happened.

The Raspberry Pi project has announced a new version of Raspberry Pi OS. It includes a number of significant changes, the most notable of which is that the Raspberry Pi Desktop now uses Wayland by default for all Pi models using the labwc compositor:

For most of this year, we have been working on porting labwc to the Raspberry Pi Desktop. This has very much been a collaborative process with the developers of both labwc and wlroots: both have helped us immensely with their support as we contribute features and optimisations needed for our desktop.

This release also features Linux 6.6.51, improved touchscreen support, a new screen configuration tool called raindrop, and more. See the release notes for a full list of changes.

The kernel graphics driver for the Apple M1 and M2 GPUs is, rather famously, written in Rust, but it has achieved conformance with various graphics standards, which is also noteworthy. At the X.Org Developers Conference (XDC) 2024, Alyssa Rosenzweig gave an update on the status of the driver, along with some news about the kinds of games it can support (YouTube video, slides). There has been lots of progress since her talk at XDC last year (YouTube video), with, of course, still more to come.

The first stable release of the Thunderbird mail client for Android is now available:

Just over two years ago, we announced our plans to bring Thunderbird to Android by taking K-9 Mail under our wing. The journey took a little longer than we had originally anticipated and there was a lot to learn along the way, but the wait is finally over! For all of you who have ever asked "when is Thunderbird for Android coming out?", the answer is – today!

It is immediately available on the Google Play Store, via GitHub Releases, or from the Thunderbird web site, and it will be "coming soon" to the F-Droid repository for FOSS Android applications. See the release notes for detailed information about Thunderbird 8.0 for Android.

Az Apple hivatalos kommunikációja szerint még meglehetősen sokára, majd jövő áprilisban.
