Arc B-Series support?

[ye-luo]

I managed to build the i915 dkms module on ubuntu 24.04 with 6.8.0-51-generic kernel, but I still don't see i915 being loaded.

$lspci |grep Intel
03:00.0 VGA compatible controller: Intel Corporation Battlemage G21 [Intel Graphics]

kernel log shows

$ grep i915 /var/log/kern.log
2024-12-23T11:40:47.497620-06:00 epyc-server kernel: i915_compat: Unknown symbol drm_dp_dpcd_read (err -2)

I'm wondering if this is caused by the lack of B-series support in the backport or I did something wrong.

BMG is not supported in i915. Please check the readme doc for the list of supported devices.

@ye-luo can you share the version tag which is used. This issue should ideally be due to header differences or kernel-header package mismatch.

My previous compilation issue #207 has been resolved.
Regarding Battlemage support, I got an answer at canonical/intel-graphics-preview#8 (comment). I will just wait for a month for the ubuntu 24.04.2 released with 6.11 kernel.
