Latest TBS-fork driver breaks i915

Postby pchristy » Sat Apr 04, 2020 4:41 pm

Slackware64-current, kernel 5.4.30 (same happens on any 5.4 kernel). TBS-6281se. Graphics device: VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)

The problem: The latest TBS-for driver completely breaks the Intel i915 driver, making it impossible to view any video from any source - tuner, local file, youtube, etc. The screen keeps freezing and blanking.

The driver compiles without error, but after installing it, i915 is broken.

Before installing driver:

Kernel-5.4.30 dmesg | grep i915
[ 6.753039] i915 0000:00:02.0: vgaarb: deactivate vga console
[ 6.753818] i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem
[ 6.755940] [drm] Initialized i915 1.6.0 20190822 for 0000:00:02.0 on minor 0
[ 6.757401] snd_hda_intel 0000:00:03.0: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915])
[ 6.797757] fbcon: i915drmfb (fb0) is primary device
[ 6.845283] i915 0000:00:02.0: fb0: i915drmfb frame buffer device

After installing driver:

Kernel-5.4.30 dmesg | grep i915
[ 7.410856] i915: Unknown symbol cec_notifier_put (err -2)
[ 7.464552] i915: Unknown symbol cec_notifier_put (err -2)
[ 16.064911] i915: Unknown symbol cec_notifier_put (err -2)
[ 16.079576] i915: Unknown symbol cec_notifier_put (err -2)

I succesfully compiled and installed the driver on kernel 5.4.14 a couple of months ago, but since I updated my kernel to 5.4.30, I updated the TBS driver at the same time. Now I get the above issue on any kernel-5.4.X. Tuner is currently useless.

Hi Sir

What about your compile steps ?
if 5.4.14 works well recommend continue use this kernel
Kind Regards
