BOINC Client will not see Intel GPU after update to 6.8.1

[debianmain1]

Describe the bug
Boinc client no longer sees the Intel GPU after the update to Kernel 6.8.1 Downgrading to 6.7.9 allows the Intel GPU to be seen.

Steps To Reproduce

1. Upgrade from Kernel 6.7.9 to 6.8.1 with an Intel GPU installed.

Expected behavior
Boinc finding Intel GPU as per normal.

Additional context
I believe that this problem is with the addition of the Xe driver in the 6.8 kernel line. I have tried to blacklist the Xe driver module from loading without success. The Xe driver "should" be made available to BOINC due to better handling of hardware. The i915 is very old & will not have the performance of the Xe driver once it matures.

Ideally, BOINC being able to handle both drivers would be optimal. In the short term, defaulting to the i915 driver & ignoring the Xe driver would allow BOINC to continue to use Intel GPUs.

Method of blacklist: In /etc/modprobe.d I added: blacklist xe & options xe modeset=0 to the blacklist.conf file. no change was noted - BOINC still would not see the Intel GPU.

System Information In screenshot below

• BOINC Version: 7.24.1

Kernel 6.7.9-zen1-1-zen:

03:00.0 VGA compatible controller: Intel Corporation DG2 [Arc A750] (rev 08) (prog-if 00 [VGA controller])
Subsystem: Intel Corporation DG2 [Arc A750]
Flags: bus master, fast devsel, latency 0, IRQ 250
Memory at 82000000 (64-bit, non-prefetchable) [size=16M]
Memory at 4000000000 (64-bit, prefetchable) [size=8G]
Expansion ROM at 83000000 [disabled] [size=2M]
Capabilities:
Kernel driver in use: i915
Kernel modules: i915

Kernel 6.8.1 -zen1-1-zen:

03:00.0 VGA compatible controller: Intel Corporation DG2 [Arc A750] (rev 08) (prog-if 00 [VGA controller])
Subsystem: Intel Corporation DG2 [Arc A750]

Note the addition of the "xe" Intel driver in kernel modules.

Any thoughts on how I can use BOINC with >6.8 until a fix is pushed? I'm fine with a manual intervention. I'm doing testing on the Xe driver in EndeavourOS/Arch & would like to avoid booting between the LTS & main kernels and ideally try to use the Xe driver for work units. A couple of projects are using the Windows Xe driver & it would be VERY interesting to see if the Linux Xe driver is compatible.

OK---Intel-Compute has been patched in Arch Linux. This now allows BOINC 8.1 to see the Intel GPU. As far as I know, this refers only to the i915 driver. Versions 7.24 & 8.0 also work with this patch. I still think there needs to be a "switch" between i915 & Xe driver usage.

I will be testing the Xe driver in Arch as soon as Mesa is updated to 24.1 (about 1 month). I will report here as to the results.

i got it to detect with an A380 after installing the compute runtime e.g.

https://github.com/intel/compute-runtime/releases/tag/24.13.29138.7

I think you could do with these now https://dgpu-docs.intel.com/driver/client/overview.html

Yes...
I noted that 2 posts above your post.....I am almost ready to test the Xe driver (next Mesa update) & will report then if BOINC works with it.
