vividspecter@aussie.zoneto Linux@programming.dev•SR-IOV Will Only Be Supported On Intel Arc Pro Graphics Cards4·17 days agoThey seem to all be committed to limiting this feature to the pro market, which is a shame. At least AMD and Intel have native context support, although it’s very early days and Linux host and guests only for now.

Don’t use social media or news sites when you wake up, or before bed
-
Block notifications from social media and news sites, or uninstall altogether

Set time limits (like with leechblock-ng on desktop, or with simple alarms)

But that wasn’t enough for the people of his electorate to go: “Err maybe this rapist isn’t the best option to represent us.”

vividspecter@aussie.zoneto Programming@programming.dev•Can somebody explain the graphics stack? Vulkan, OpenGL, Magma, DirectX, SDL, Metal, Mesa, ... wat?2·1 month agoI’m not really an expert, but I’ll try and answer your questions one by one.
Don’t VMs have a virtual GPU with a driver for that GPU in the guest that, I imagine, forwards the graphics instructions and routines to the driver on the host?
Yes, this is what VirGL (OGL) and Venus (Vulkan) do. The latter works pretty well because Vulkan is more low level and better represents the underlying hardware so there is less of a performance overhead. However, this does mean you need to translate all APIs one by one, not just OGL and Vulkan, but also hardware decoding and encoding of videos, and compute, so it’s a fair amount of work.
Native contexts, in contrast, are basically the “real” host driver used in the guest, and they essentially pass through everything 1:1 to the host driver where the actual work is carried out. They aren’t really like virtualisation extensions as the hardware doesn’t need to support it AFAICT, just the drivers on both the host and the guest. There’s a presentation and slides on native contexts vs virgl/venus which may be helpful.
Where in that does Magma come in? My guess is that magma sits in the guest as the graphics driver and on the host before Mesa, but I know little about virtualisation outside of containers.
To be honest, I don’t fully understand the details either, but your interpretation seems more or less correct. From looking at the diagram on the MR it seems that it’s a layer between the userspace graphics driver and the native context (virtgpu) layer on the guest side, which in turn communicates with another Magma layer on the host, and finally passes data to the host GPU driver, which may be Mesa but could also be other drivers as long as they implement Magma.
The broader idea is to abstract implementation details, so applications and userspace drivers don’t need to know the native context implementation details (other than interfacing with Magma). And the native context layer doesn’t need to know which host gpu driver is being used, it just needs to interface with Magma.
vividspecter@aussie.zoneto Buildapc@lemmy.world•Rate my Build: Long time since a hardware upgrade, and finally making the jump to Linux7·1 month agoI’d probably get the 9070 XT over the 7080 XT, just for full performance FSR4 (there’s some compatibility with it on Linux, but it’s slower). Maybe even the non-XT model for the same reason.
I feel like you might be able to do better price wise on the RAM, although I’m not up to date on current prices for DDR5.
EDIT: I see you have an itx case, so maybe that limits your GPU options a bit.
vividspecter@aussie.zoneto World News@lemmy.world•‘Japanese First’ party emerges as election force with tough immigration talkEnglish23·1 month ago“Globalism” invariably means some sort of conspiracy theory, usually about Jews. Given this party are also anti-vaxxers, that’s the most plausible conclusion.
And a broader coalition among the rest of the Western countries including Europe and Australia/NZ etc makes more sense than duplicating effort in every country.
vividspecter@aussie.zoneto Programming@programming.dev•Can somebody explain the graphics stack? Vulkan, OpenGL, Magma, DirectX, SDL, Metal, Mesa, ... wat?6·1 month agoThe other points have been answered, so I’ll try and give a surface view of Magma. It’s basically an abstraction layer for virtual GPU drivers used in VMs. Currently, you need specific implementations to handle all of the pathways between different types of VM guests and hosts, which gets complicated fast, and duplicates a lot of work. The idea is the Magma abstracts this away, and so host and guest GPU drivers only need to interface with Magma. Which means you can swap out different host OSes/GPU drivers and different guest OSes and GPU drivers, and as long as they interface with Magma, they should “just work”.
Of course, whether it will work out that way in practice remains to be seen. I think Google is using it internally but it’s not in Mesa yet, so it may not even roll out widely. You can follow the MR if you want more detail or to see its progress.
If you’re wondering why Google is implementing this it appears to be for Fuschia and Android, and compatibility between those two and with desktop Linux, with Windows support also supported as an additional value add. Chromebooks in particular should benefit from this, since ChromeOS is being retired I believe.
And as an aside, unlike some of the traditional GPU implementations you’d find in VMs, these are or will be pretty much just the normal graphics driver that you’d use on the host. They are generally called “native contexts” and have been implemented for AMD and Intel at the least, but only on non-Windows systems for now. These implementations alone, once they are widely supported, should result in near native GPU performance in VMs, without having to use GPU passthrough (I.e. passing through a physical GPU to the VM guest). So even without Magma there’s some promising stuff happening, albeit mainly on the Linux host -> Linux guest pathway.

There are theoretically some cases where zram can be harmful, but in general I find it works reliably.

vividspecter@aussie.zoneto politics @lemmy.world•Zohran Mamdani appears to pull ahead of Andrew Cuomo, according to new poll2·2 months agoI’ve just never personally voted using RCV on a ballot that requires you to rank that many candidates for a valid ballot. That seems unnecessary.
Several implementations of it in Australia are full preferential, and require ranking all candidates (and there’s a kind of hybrid optional implementation in the federal senate where there is a minimum but you can rank as many as you want). The NYC one is still optional preferential actually, which is in my view a bad system because people get tricked into “just voting 1” and their vote consequently has less power to influence the result.
Hopefully this is as far as it goes and not something they will continually restrict each year. This feels similar to the Xiaomi situation which seems to have had the same problems in China, and they have gradually restricted unlocking more and more.
