Include the graphics VBT file in DTS HCL log dumps #1118

Open filipleple opened 6 days ago

filipleple commented 6 days ago

The problem you're addressing (if any)

One crucial component of firmware is the graphics VBT file. Right now, we either have to extract it from stock firmware (and usually guess which one to use), or boot Linux and obtain the working file ourselves.

Describe the solution you'd like

We can find the active, working VBT in debugfs, at /sys/kernel/debug/dri/0/*_vbt, for example i915_vbt. This can be automatically copied and included in the HCL dumps.

Where is the value to a user, and who might that user be?

It would reduce time spent on a trivial, repetitive activity and make the HCL dumps even more useful

Describe alternatives you've considered

+1, I've also recently wished we dumped the active VBT in HCL reports

Can be done. But I noticed the VBT from sysfs is 3 bytes smaller than should be... Not sure what is the cause of this.
