Dear Genodians,
I'm trying to enable Genode on the apu2c4. I successfully could run the test-pci component using branch [1] based on Genode 17.11:
However, using the genodelabs/master branch results in a ACPI parsing error: ´[init -> platform_drv] Error: ACPI report parsing error.´
I set the report_rom to verbose and I noticed following differences:

Cherry-picking from [1] to the master branch didn't help.
On QEMU I noticed a ´bdf´ node in the acpi_report. ´platform_drv´ is expecting this node. The ´bdf´ node is written in ´Acpi::generate_report()´ but only if there is an entry in the ´Pci_config_space´ list. The only function that inserts something to that list is ´Table_wrapper::parse_mcfg()´, which is called from ´Acpi_table::_parse_tables()´ in case one of the tables has the "MCFG" signature. However, none of the tables seem to have that signature.
And now I'm lost. How do I move on?
Cheers, Sid
Hello Sid,
because of [0] you need with 18.05 a valid MCFG ACPI table to run Genode on x86. The general answer is, that coreboot or companion must provide the tables, otherwise you are out of luck. Maybe the hints at [1] are helpful to start investigation for you coreboot build ?
Cheers,
Alex.

Fortunately, the pcengines coreboot maintainers are awesome people and interested in enabling cool use cases :)
I pointed them at this thread and briefly described the situation & motivation, and a MCFG table is now pending review! [1]
If you aren't afraid of reflashing, you may already be unblocked :)

Cherry-picking from [1] to the master branch didn't help.
On QEMU I noticed a ´bdf´ node in the acpi_report. ´platform_drv´ is expecting this node. The ´bdf´ node is written in ´Acpi::generate_report()´ but only if there is an entry in the ´Pci_config_space´ list. The only function that inserts something to that list is ´Table_wrapper::parse_mcfg()´, which is called from ´Acpi_table::_parse_tables()´ in case one of the tables has the "MCFG" signature. However, none of the tables seem to have that signature.
And now I'm lost. How do I move on?
Cheers, Sid

thanks (and of course the pcengine maintainer) for the efforts. Let's see what Sid will tell us.

Hello Sid,
because of [0] you need with 18.05 a valid MCFG ACPI table to run Genode on x86. The general answer is, that coreboot or companion must provide the tables, otherwise you are out of luck. Maybe the hints at [1] are helpful to start investigation for you coreboot build ?

Hi Jean-Philippe, and Michal,
thanks for pointing Michal to this thread! And Michal, thank you so much for the quick fix! I just built the coreboot image including your patch with the MCFG table. Unfortunately I don't have a device with me. Will test tomorrow morning and give feedback then.
Cheers, Sid

Cherry-picking from [1] to the master branch didn't help.
On QEMU I noticed a ´bdf´ node in the acpi_report. ´platform_drv´ is expecting this node. The ´bdf´ node is written in ´Acpi::generate_report()´ but only if there is an entry in the ´Pci_config_space´ list. The only function that inserts something to that list is ´Table_wrapper::parse_mcfg()´, which is called from ´Acpi_table::_parse_tables()´ in case one of the tables has the "MCFG" signature. However, none of the tables seem to have that signature.
And now I'm lost. How do I move on?
Cheers, Sid
