mort_, lina: re the discussion about cursor latency on reddit: Is it possible to update the cursor plane independent from the rest of the planes?
<Company>
then you could do a compositor that does vsync for the main image and low latency for the cursor
<zamundaaa[m]>
Company: KWin already does that, as far as KMS allows
<zamundaaa[m]>
An AMEND flag to allow you to amend the last atomic state even after the pageflip has happened (whenever possible) has been talked about before, but never went anywhere unfortunately
<Company>
would that mean that kwin should have lower latency in mort_'s test?
<zamundaaa[m]>
Company: possibly. I haven't looked into it too far yet
<zamundaaa[m]>
I did build myself a latency measurement thing for a different reason though, so I may test legacy vs atomic cursor movement soon-ish
<Company>
I'd be interested in that

Does Linux have any analog to D3D12’s concept of reserved resources? The Windows kernel implementation is apparently designed to have the GPU update its own page tables, which seems rather strange and tricky because it requires the kernel driver to generate GPU commands to do that.

Just yesterday I discovered this crazy Vulkan issue on AMD, where you have to use vulkan-radeon instead of amdvlk. Seems the usermode driver is broken at times? https://wiki.archlinux.org/title/AMDGPU#Installation
<HdkR>
phasta: Most people here would recommend radv over amdvlk anyway
<HdkR>
Which is what the vulkan-radeon package is
<phasta>
HdkR, but why? And why are they even interchangeable?
<HdkR>
phasta: Because there are two Vulkan drivers for Radeon hardware. AMD's proprietary driver (amdvlk) and the mesa based one (radv)
<phasta>
He. Open 1:0 Proprietary
<HdkR>
The proprietary one is also technically open-source :)
<psykose>
they're both 'usermode' (in userspace)
<HdkR>
That too
<glehmann>
but throw-over-the-wall opensource
<glehmann>
and there is also the proprietary amdvlk-pro (which shares everything but the compiler with amdvlk non-pro)

Where does ACO fit in?
<glehmann>
ACO is what radv uses now, it's part of mesa
<glehmann>
-pro has faster compile time than LLVM (not hard), higher ones than ACO. Tends to produce better asm than LLVM, sometimes also better than aco
<glehmann>
but ACO also does somethings a lot better than either of the other two, mainly control flow and divergence things
<glehmann>
I'm also biased as I work on ACO :P
<DemiMarie>
Is LLVM only used for amdvlk (non-pro), ROCm, and OpenGL?
<glehmann>
I think so, radv has an debug option to use LLVM but that's mostly unmaintained and just for testing.
<pixelcluster>
alyssa: yeah pretty much exactly what you said, "scratch" is really just space in per-function stack
<pixelcluster>
that's what the ACO implementation of "real" function calls does too, it just adds the current shader->scratch_size to each function's stack

I don't see how that MR can possibly affect any driver other than intel & asahi
<logsoutofbound>
I did all the implementation of the compression specification hdd storing routines, linkage of the format and execution as well as decoder encoder, which remained so that out of it, we use a small lookup table to fasten the routine cause of IO writes need full value, and encoder uses a loop or dma. I studied processors for long time, and i customize the routines to performance
<logsoutofbound>
to understand, as said the system is designed for it naturally due to powers of twos presentation, it can selecitively target banks and elminate the reverse banks with two indexes that get shared. There are many methods but i had already spoken about very intiuitive ones, which is shared index and contiguous base etc.
<logsoutofbound>
considering reordering and operand forwarding or safety and security, however the compilers skeleton was pushed by other people to the net, that i ended up using, cause i am bit lagging behind. Io digged out loops to insert my routines in the wasmati kit, and this is my last interaction before we already have the compiler functional, cause the specification for execution is bit simpler
<alyssa>
i don't think that MR could have possibly affected v3d

Meson's subprojects are always built for the host machine, which is because the people who drove that basically wanted to be able to build a GTK/Gnome SDK.

sure
<grandmanback_>
is there also some confusion as to how the powers would be taken according to the Cornell formula? i took them from 32 then 34 which is smallest non colliding distribution where i encoded second operand differently, however technically any contiguous distribution can be taken and the formula makes them work through eulers imaginary numbers that get rounded up, since we want to present
<grandmanback_>
them in fixed integers format, so logic imply collision on first 8powers due to gaps being too small, i do not know what is ideal distribution from previous papers, but 15 is more than enough for first negative logarithm to avoid float based format. so i put 15to79 for example to the calculator of binary distribution.

However that thread would end up working fine for single data storing, btuu
<notestsforjunk>
would not suite for compute paradigm of execution, and the most certain way of taking non-colliding compute format quickest is not that hard, so that the formulas result of first power would be bigger represented than the number of the one after the middlest number, and have some type of contugous curve, you can then bet on anything that no single duplet will collide. I am unsure if
<notestsforjunk>
you overtry or are under any stress or something, but that is just logics i took 15 before cause there was a mistake in my formula, but the before format would suite if you handle second operand with shifted operands like said in the paper? People, it is not so hard at all.

So of course it is solved, and the compute mode is easy surely, but this underlying code is not something i want to upload , it's a whole lot simpler than your methods, the data access method in pseudo code was given to very smallest format, so that you can allocate a base where minus and plus goes to two different hashes interchangably there is no more efficient method possible, if
<notestsforjunk>
you have the skills based of the code i see you have uploaded i.e if you dd this yourself, you can make it easily yourself, however d3d11 and 12 is dangerous as it is microsoft api, and microsoft is not holding a monopoly anymore in fair use doctrine terms, since mobile business is for android and ios exclusively, they can sue people for using or distributing it illegally.
<notestsforjunk>
so instead we have opengl and vulkan, where the biggest reach is opengl es2 that really is a monopoly as of today.
<notestsforjunk>
there is no technical problems to developo very quickly many working trees of d3d12 and 11 which would never fail however, there are legal problems around it.
