Venemo: As of next Mesa release, all supported HW will have a Gallium driver?
<FLHerne>
Iris/Crocus take away the "doesn't work on Intel" thing
<FLHerne>
I suppose everyone has to support the Nvidia blob though :-(

Is it just me or is driver_location mostly useless?
<bloom>
If set early, other passes stomp over it
<bloom>
If set late (i.e. after lower_io), it doesn't propagate to the intrinsics
<bloom>
jekstrand: ^
<bloom>
I mean I guess it's used internally in NIR for things
<bloom>
but it's hardly /driver/_location at that point
<bloom>
for actual driver location I think you need an out-of-band thing ...

mareko: FLHerne I meant that many DXVK users are on NVidia's proprietary driver
<Venemo>
bloom: after lower_io you need to deal with the IO intrinsics individually and not the variables. What are you trying to do?
<bloom>
Venemo: remap varying locations to make room for driver-internal state and packing
<bloom>
which the more I think about it seems even more silly and impossible to work in light of separable shaders
<bloom>
so err I think that's my cue to try to understand the hardware better ....
camus has joined #dri-devel

bloom: which driver are you working on?
<bloom>
asahi (apple)
<Venemo>
Well, if you do that before lower_io then the variables' driver location is what you need to set
<bloom>
That's what I thought, but that doesn't work if you call any other NIR pass that wants to remap driver locations / bases itself
<bloom>
nir_lower_mediump_io was the culprit for the bug I chased down tonight, but grepping nir it looks like there might be other passes that do similar things ... so apparently this is not something that we can expect to work for NIR
alyssa has left #dri-devel [#dri-devel]
<Venemo>
Usually the passes don't really need to touch driver locations, but rather the driver has a place that sets it
<Venemo>
For example, radv_set_driver_locations
<bloom>
so maybe this is just a nir_lower_mediump_io bug and not a NIR wide problem?
Daanct12 has joined #dri-devel
<Venemo>
What exactly is the bug? nir_lower_mediump doesn't seem to touch driver locations

moving the very last bits of gitlab.fd.o to our new hosting is still underway and this is going to blow through our 11am UTC estimate; if you're hanging on to see it come back, please instead go for a walk in the sun, make yourself a really nice breakfast, read the 234987 tabs you've promised yourself you'll definitely deal with one day, clean the kitchen, or some other kind of Sunday activity, and we should be back for midday UTC

rpi4 really wants mediump (twice the mul throughput, and takes half the register storage and spilling is hard to do) but the mesa compiler doesn't do it yet.
