• Fix USB

• Fix SD card

• Audio input

• verify display driver

• APX

• battery charger

Misc

• check all ACPI PowerResources/GPIO again

• finish battery driver

• get wifi to work

• convert edid to display timings and add it to devicetree

• patch UEFI Shell GOP

• does WinButton work without daughter board? No: Windows button is connected to Screen digitizer

• run i2c detect without daughter board (MPS430?)

• add a picture for every IC and its location.

• revisit i2c patch. maybe no need to patch 10bit address check

• add pictures of every IC + location on mainboard

• XDA update

• create a lot more documentation on how i got xyz working. (identifing sensor, logic analyzer, bla bla)

• Fix devicetree always on regulators

• empty I2C bus? try different pinmux; CAMS?

• check BDID whith others

• What is open Surface RT? OpenSource, OpenHardware, OpenedDevice

• unixbench: apx vs efi

• UC3L chip: SensorCollection or EmbeddedController or both?

• Research how Uefi blocks LDO5 writes

• Create minimal .config

• Explain the root and rootwait param

• switch from UEFI shell to grub

• "shim" which sets conout before chainloading other files.

• early uartE with efistub pinmux setting

• use initrd as rootfs? Yes: root=/dev/ram0

APX

• apx uboot devicetree

• apx devicetree

• apx 1gb ram

• operation performance points (OPP)

• tCover

• implement thermal zone

• Wifi: reboot from UEFI to apx and see if wifi works. A: no

BATTERY

• POWER_SUPPLY_PROP_STATUS + polling for capacity change

• POWER_SUPPLY_PROP_PRESENT

UEFI

• Examine all ConOut handles to see why it picks the wrong one.

• Examine all ConIn handles to see if tCover is possible.

sRT & s2

• Bluetooth firmware

• Ram timings

• Some sensor drivers (hinge)

TCOVER

• tCover APX

• Does N0 power the tCover??

• explain WDSA table

• check how flipping back tCover brings up screenKeyboard; A: Sensor Collection/Hub

AUDIO

• Headset Mic (Bias + right input)

• Digital Stereo Mic (right gpio combination)

SENSOR COLLECTION

• 0x28 power resource

• learn about the sensor collection (0x28)

UEFI STUB

• use appended devicetree if no dtb= param is provided

distro installer

• small buildroot which can format eMMC and download/install distros

after everything is done

• rip out dead mainboard and put raspi in.

• case mod with some glass and RGB LEDs (+300MHz) @jwa4

• USB Type-C mod with PowerDelivery. Charging, data and maybe video out @LeYuuki

• port downstream kernel

• make bugles gpu 3d hardware acceleration driver @Leander
