Haiku not booting on Lenovo Thinkbook 14 with Iris Xe Graphics

[m0do1]

Hi,

I have also posted this on the forum some time ago (​https://discuss.haiku-os.org/t/haiku-does-not-boot-on-lenovo-thinkbook-14/11188).

Haiku fails to set a display mode and booting hangs on the rocket icon. I have added some simple debug code to better trace back what is happening. The output of this is also included in the attached syslogs. The first part of this additional output is always the function name in servers/app/Screen.cpp which is followed by some information on what is going on. Syslog_1 is what I get.

From what I can see the call of status_t status = fHWInterface->SetMode(mode) in Screen::SetMode never returns.

I have also tried to manually set status to B_OK. This obviously also does not work, but it gives slightly different output. See syslog_2 and the attached screenshot for this.

From my output it looks like the best mode has a strange resolution. Thus I have also tried to set a resolution manually. This also does not work.

Additionally I have tried all these things also with the fail-save drivers which results in the same behavior.

Also I attached the lspci output from Linux on the same machine.

The syslogs here are using the latest commit "03ed104900142edb52bff17af8ce4a14b755dfa0 - intel_extreme: enabled all known skylake gfx cards since they are pgm'd now" and haiku is compiled from source.
