Patch Set #119, Line 12: - Booting Fedora 31 using TianoCore (CorebootPayload)
What Linux kernel version does it ship?
Done
File src/mainboard/acer/aspire_vn7_572g/Kconfig:
Patch Set #119, Line 13: # TODO: select DRIVERS_NVIDIA_OPTIMUS
more TODO
Optimus support is implemented in CB:28380 and is not yet merged.
Also see above (on dsdt.asl, regarding optimus_mb.asl).
#config TPM_PIRQ
# hex
# default 0x1e # GPP_A6_IRQ
remove if unused?
The schematics specify a Nuvoton NPCT650 appearing on the LPC bus.
However, the model that I own does not have this chip. If it did, this pin would be its interrupt.
I'm not sure whether this should stay or be removed.

Ack. I wonder if the issue with the Purism Librem is due to lack of HSIO tuning or just bad design. […]
I resolved this by enabling "SataPwrOptEnable"
File src/mainboard/acer/aspire_vn7_572g/devicetree.cb:
# TODO: register "PcieRpAspm[9]" = "ASPM_L1"
# TODO: register "PcieRpL1Substates[9]" = "L1_SS_DISABLED"
lets resolve these TODOs (and the one above) is possible before merge
This depends upon CB:39538.
The microphone, however, is more complicated. I can assume that the vendor is using that UPD to enable the microphone as none of the HDA pin_cfgs address a microphone and I'm including all of their undocumented verbs (extracted from the InstallPchHdaVerbTablePei module).
However, the microphone isn't working even with the vendor firmware.
File src/mainboard/acer/aspire_vn7_572g/dsdt.asl:
Patch Set #119, Line 29: // #include "acpi/optimus_mb.asl"
the file is in this patch, so is it just not working or?
Optimus support depends upon CB:28380 and requires implementation per-SoC. I've attempted to write peg.asl for Skylake (CB:40625), but with this applied, the dGPU does not appear in the OS at all.
