Error loading i915 driver (intel_vsec_register issue) #74

Closed mregmi closed 1 year ago

mregmi commented 1 year ago

We tried various tag combinations to build and load the i915 and pmt driver. We are still seeing the issue while loading the i915 driver. The dmesg its complaining about the Vsec.

[508819.288281] i915: Unknown symbol intel_vsec_register (err 0)

We are using RHEL 8.6 and kernel 4.18.0-372.26.1.el8_6.x86_64 More details in #73

The tag combinations we tried: i915: RHEL86_22WW52.3_540_6379.0.13.221103.16 pmt: 22WW45.5_476.14_RHEL86

i915: RHEL86_22WW45.5_476.14_6213_220914.2 (we also tried .1 version which was released 1 day before this) pmt: 22WW45.5_476.14_RHEL86

@mregmi - What was the solution to this issue. I am hitting the same thing on RHEL 8.8. Please update with the solution or a link to the solution.

export KBUILD_EXTRA_SYMBOLS=/build/intel-gpu-pmt-backports/drivers/platform/x86/intel/Module.symvers && make
