The sheng firmware modules are generated from the official fastboot archive inside the build (UniXNU-sheng import-sheng-uefi.py); no binary repository carries them.
uefi-sheng
UEFI platform integration for the Xiaomi Pad 6S Pro (sheng, SM8550), using Project Silicium and Project Mu.
The platform supplies memory reservations, board peripherals, display handoff, and the firmware volume. UniXNU supplies the boot application and DarwinBoot loader. UniXNU-sm8550-common supplies shared XNU platform support.
Payload firmware
Build through ./unixnu build firmware --uefi ../uefi-sheng from UniXNU.
The DSC and FDF include UniXNURamDiskDxe, DiskIoDxe and FAT support so the
boot-image payload appears as a filesystem. UniXNURamDiskDxe is a shared
module in UniXNU's package/, and uses the Mu-Silicium FDT handoff.
ShengBootMemoryDxe supplies the board's memory expansion policy.

Device porting record
The firmware section of sheng's porting record
records handoff inputs, development findings, evidence and completion criteria.
Update UniXNU-sheng/porting.toml when firmware work changes those inputs or
results. Maintainers and agents use the same workflow.
Local build inputs
Save device paths and boot arguments in unixnu.local.toml in the UniXNU
checkout. See the configuration reference.
Then use ./unixnu kernel, ./unixnu firmware, ./unixnu payload, and
./unixnu bootimg. Argument changes require rebuilding the payload and boot
image. See boot arguments
and green-bar diagnosis.
