Surface Pro for Business 11th Edition with Intel — Core Ultra 7 268V (Lunar
Lake). The repository has surface_pro_11_qcom but nothing for the Intel
variant, so the directory follows the surface_laptop_3_intel /
surface_laptop_7_qcom naming.

DMI product : Surface Pro for Business 11th Edition with Intel
DMI SKU     : Surface_Pro_11th_Edition_With_Intel_For_Business_2103
UEFI        : 17.100.143 (2025-11-19)
Dumped on   : Ubuntu 26.04.1, kernel 7.0.0-30-generic, acpica 20251212

One table is missing, on purpose

ssdt17.dsl is not here. iasl refuses that table:

Firmware Error (ACPI): Failure creating named object
  [\_SB.PC00.I2C0.FINK._CRS], AE_ALREADY_EXISTS
Could not parse ACPI tables, AE_ALREADY_EXISTS

It redefines a _CRS that already exists, and acpica 20251212 fails on it
whether disassembled alone or with every other table passed via -e. A
zero-byte file seemed worse than an absent one.

This is worth flagging rather than leaving as a puzzle, because SSDT17 is
where the Surface-specific devices live
on this machine — MSHW0585
(touchscreen and stylus digitizer), MSHW0040 (volume/power buttons),
MSHW0153, and 1FC93002 (the NXP NFC controller). Their bytes are in
acpidump.txt, which is complete; only the readable form of that one table is
unavailable. The other 34 disassembled cleanly.

I have added a short README.md, which I notice no other directory here has.
Two reasons for making the exception: this is a machine nobody has dumped yet,
and the absent ssdt17.dsl needs an explanation that outlives this pull request
— in six months the omission would otherwise read as carelessness. If you would
rather the tree stayed uniform, deleting one file costs you nothing.

Context

This came out of getting the machine working under Linux. Audio needed two
kernel patches, currently in review on linux-sound:
https://lore.kernel.org/linux-sound/20260830084500.6123-1-lsa.uz@pm.me/

The cameras are still broken — int3472 does not handle GPIO type 0x08,
which ICL0 in this DSDT declares — reported separately to
platform-driver-x86. Anyone wanting to check that against the firmware can now
do so from this dump.

Happy to re-dump with different tooling, add anything missing, or adjust the
layout to whatever you prefer.

Microsoft Surface Pro for Business 11th Edition with Intel, Core Ultra 7 268V
(Lunar Lake). DMI SKU Surface_Pro_11th_Edition_With_Intel_For_Business_2103,
UEFI 17.100.143. Dumped on Ubuntu 26.04.1, kernel 7.0.0-30, acpica 20251212.

The repository has surface_pro_11_qcom but no dump for the Intel variant.

ssdt17.dsl is absent: iasl cannot disassemble that table, failing with
AE_ALREADY_EXISTS on \_SB.PC00.I2C0.FINK._CRS whether disassembled alone or
with the other tables given as external references. A zero-byte file seemed
worse than none, so the omission is explained in a README instead. The table's
bytes are in acpidump.txt regardless, which matters here because SSDT17 is where
the Surface-specific devices live - MSHW0585 (touchscreen and stylus), MSHW0040
(volume/power buttons), MSHW0153, and 1FC93002 (the NXP NFC controller).

The other 34 tables disassembled cleanly.
