System Information
Operating system: Windows 10 Home version 22H2 OS build 19045.2965
Graphics card: AMD Radeon RX 5700XT, AMD Software: Adrenalin Edition Version 23.4.3

Blender Version
Broken: 4.0.0 Alpha, 2023-05-19 21:45, 33c13ae6e3, main
Worked: Don't know? Have not seen the feature that causes issues before, perhaps because I only update every couple of weeks to months.

Short description of error
When I try to use HIP for rendering of a scene in Cycles, any scene I'm pretty sure, I cannot. Any attempt to do so returns the "failed to create HIPRT context" error, even though, since my card is incapable of accelerated ray tracing, I have the check box that's supposed to enable the experimental feature not checked (it doesn't matter anyway, same error regardless).

Exact steps for others to reproduce the error
I... am not sure? As far as I can tell, there's just no way for me to use HIP in any Blender version with the HIPRT feature implemented, in spite of the supposed toggle being in place, and the assurances of shader fallback. Similarly, I'm pretty sure I can't update my driver, since... my card isn't capable of RT, and so is not even listed as compatible under the beta release driver I found in a thread on here. Which leaves me simply unable to do anything to make HIP work at all. I'm not sure what steps would be needed to reproduce it, whether it is a fluke, or what. My GPU drivers are as up to date as compatibility will allow, and I'm literally trying to just use normal HIP without RT.

Tested this on an old install of 3.6.0 Alpha, and it still didn't work, although this time it said "HIP binary kernel for this graphics card compute capability (10.1) not found." instead. Rolling back to my even older install of 3.5.0 Alpha enables me to render, although I'm not sure to what degree GPU utilisation is achieved there. I'm gonna go test the current 3.6.0 Beta version, now, see if it was fixed and re-broken or just has been broken since 3.6.0 in general.

Okay, the current 3.6.0 Beta build also returns the same error as the 4.0.0 Alpha build ("Failed to create HIPRT context.").

Just to clarify this report - Blender gives error whe you render with HIP? And you say this worked in 3.5 version?

Yes. It differs what error I get depending on the version, and doesn't work in any version after the current stable release, which last time I checked was 3.5.1, I think? There it works fine and speeds up rendering a fair chunk compared to CPU only, so I reckon it does truly work. But in later versions, in the ones predating the HIP RT implementation I get a missing binary kernel message, and in the ones that have implementations of HIP RT, I get the error that it fails to create HIPRT context.

As far as I can tell my OS and drivers are as upto date as possible, and I tested 4.0.0A, 3.6.0B, and 3.5.1S on the latest releases at the time of writing, and found the problems on all versions later than 3.5.1S, and moreover I also found the same issue in a rather old historical build of 3.6.0 back from when it was in Alpha, which to me suggests that something was broken in the move from 3.5.x to 3.6.0, and has been broken for a while. It's possible it's an issue with my specific configuration, and to that end I am very willing to help examine the specifics by providing extra info, but whatever the case may be, yes. Blender errors when I try to render with HIP and include the GPU in it by checking the box in the system tab of preferences, and it works in 3.5.x versions on my end.

Let me know if I should edit the original report and thread title to reflect my most recent findings, for ease of access.

I do have RX 5700XT, but on Mac machine, so I can't check. @JacquesLucke I see you have similar GPU and Windows, can you check?

@Astra-Kaim I assume this happens with all files, is that correct? if this is happens with only specific siles, please upload sample for testing.

I actually don't have windows currently unfortunately. Updated my entry in https://wiki.blender.org/wiki/Process/Hardware_List

@iss As far as I've been able to tell, yes, as it happens even when I remove the appropriate version's folder under C:\Users\<username>\AppData\Roaming\Blender Foundation\Blender and run with factory settings loaded from the download, only altering the settings necessary to enable HIP with the GPU active, and to switch from the Eevee default to Cycles GPU Compute. That in itself reproduces the error.

@Jeroen-Bakker do you have hardware/OS to check?

To my knowledge the AMD 5000 series doesn't have hardware raytracing support. It might be that some logic isn't correct as HIPRT shouldn't be used at all, but continue with HIP (without RT).

@BrianSavery can you have a check on this issue?

@Jeroen-Bakker You're correct about RX 5000 series GPUs not having RT support. However, the concerning thing is that my testing showed that HIP is broken in any version higher than the current build of 3.5.1 Stable, even though only the most recent ones of those even support HIP RT. The error is different, saying the binary kernel is missing, but the result is the same, that is, no rendering happens. Rolling back to 3.5.1, I'm pretty sure it works fine, though... which makes me pretty sure that it's not a driver or OS problem, since if that was the case, older versions wouldn't work either. ...unless of course 3.5.1's implementation is broken in such a way that it only says it utilizes the GPU, while not actually doing that, but based on my limited testing that seems unlikely since there is a performance boost for CPU+GPU compared to CPU only, with HIP.

@Astra-Kaim hi, does cycles render work without HIPRT in recent builds?: https://builder.blender.org/download/daily/
HIPRT is only supported for RDNA 2 architecture GPUs: 557a245dd5

Uh, it would seem so, thanks for the reminder! The problem is actually gone it seems; that is, with HIP RT unchecked (as it should be on 5000 series), with both CPU and GPU boxes checked, with Cycles rendering selected, with GPU compute selected, it now renders out fine, both on a brand new stock default cube file, and on my old projects opened upon loading 3.6 settings.

That is to say, I think you can close the ticket, now, as the issue appears to have been resolved! I can go back to using recent Blender versions for my projects. :)
