NVIDIA have put out a new Vulkan beta driver with better pipeline creation performance

Quoting: jensSo you had an interview with somebody from the Nvidia management?

It's not developers' decision, or you expected otherwise for some reason? Actual Nvidia Linux developers said as much, that it's their management that has to do something for better collaboration.

And it is jerk behavior from that management, either we move on or it, we should call it what it is.

You called their management people jerks, so I guess you ever talked to one of them and can justify your statement? See above, if you don't like their decisions, just fine and you are rightful to do that. But calling someone a jerk you have never talked to (my assumptions) is just cheap and below every level.

I did. Because they are not upstreaming their kernel driver and preventing nouveau from doing it for them efficiently.

Here is a relevant quote from Ilia Mirkin, one of the developers of Nouveau:

QuoteReclocking must be done in firmware. NVIDIA now requires signed firmware to access a lot of useful functionality. They will never release the firmware in a nice redistributable manner, so the avenues for implementing it become much harder:

(a) Figure out a way to extract the firmware from their released drivers (harder than it sounds) and how to operate it to do the things we need
(b) Find a bug in their firmware to use to load our own code into the secure environment (any such exploit would be patched, but once we have a version of the firmware that's exploitable with signatures, we can just keep loading it instead of whatever's the latest)

Of course all that gets us is ... firmware which can toggle stuff GPU-side. Then we have to develop the scripts to actually perform the reclocking to pass on to the firmware. This is the hard part -- due to the wide variety of hardware, ram chips, etc there can be a lot of variation in those scripts. A single developer might only have 1% of the boards out there, but by fuzzing the vbios and seeing how the blob driver reacts, we can get much more significant coverage.

As part of the signed-everything logic, the blob driver now also verifies that the VBIOS hasn't been tampered with, which means that developing reclocking scripts will require different techniques.

Moral of the story... just get an Intel or AMD board and move on with life. NVIDIA has no interest in supporting open-source, and so if you want to support open-source, pick a company that aligns with this.

Yes, I call that jerks, because it's totally in their ability to do it. They don't want to, since they want to control the market by using their driver. Functional nouveau will totally bust that ability, since it will let users themselves decide how to use their hardware.

Once again, feel free to disagree what Nvidia is doing and be happy with your choice for your preferred hardware vendor.
I made my point that I would refrain from name calling, especially if one has never spoken to one of their (management) people.

I did exactly that by using AMD. I surely disagree, and see nothing wrong in saying that Nvidia's behavior is nasty. What I find strange on the other hand, are attempts to whitewash it, especially coming from Linux users who should know better.

So I'm a jerk too because I don't like name calling and respect others decisions, even if I don't agree?

That's a shaky moral stance I'd say ("I respect any decisions no matter what they are"). I don't respect decisions that are done for anti-competitive purposes, which is the case here.

No NVidia (or Intel/AMD whatever) manager has ever beaten me, so I really feel no need to call one a jerk :). I'd state that I don't agree, vote with my wallet and just move on.

@Liamdawe

Please moderate theme, discussion goes to other things non related with this release driver

^_^
