Lenovo TB132FU Android 17 device product

This is the hardware-complete native Android 17 device product for the Wi-Fi Lenovo Tab P11 Pro (2nd Gen), model TB132FU. It replaces system, system_ext, and product while retaining the accepted non-GKI boot pipeline and stock vendor/ODM/firmware/calibration partitions.

The published product is intentionally plain aosp_tb132fu. It contains no Google application packages, private signing keys, or private release inputs. Those may be composed in a separate local product layer without changing this device-owned hardware tree.

Supported lunch targets are aosp_tb132fu-cp2a-userdebug and aosp_tb132fu-cp2a-user. The open tree keeps AOSP-sized logical-image ceilings; larger private package compositions must define and validate their own measured partition ceilings rather than silently resizing the tablet's saved super geometry.

Required kernel

Pure Pixel 17 R6 and this Android 17 device product use the separately maintained TB132FU Kernel #52. R6 retains the physically qualified R5 kernel implementation unchanged:

• release source: tb132fu-purepixel17-r6-k52
• qualified kernel-source commit: 6eadba53b576
• kernel release: 4.19.325-cip135-st19+ #52

Kernel #52 retains the Kernel #17 hardware, charging, autofocus, and ABI baseline plus the physically qualified K51 display/audio implementation. It restores the TB132FU DisplayPort transmitter, produces correct-pitch 48 kHz HDMI stereo with independent left/right channels, rejects the unsafe 4K30 path, and offers 4K60 only when the trained sink/link reports both DSC and FEC. Its -st19 suffix is the imported CIP staging level; #52 is the independent TB132FU build counter.

This device tree intentionally sets TARGET_NO_KERNEL := true: it builds the framework-owned Android images but does not assemble boot.img. A flashable TB132FU boot image also requires the matching kernel configuration, DTB, ramdisk, Android boot-header geometry, and AVB metadata. Follow the kernel repository's build documentation and the matching ROM release process rather than flashing a standalone Image or Image.gz.

The user variant also sets ro.adb.secure=1; USB debugging remains a user choice, and enabling it on the unlocked tablet still requires an authorized host key.

The device product expects the exact stock Lenovo pen service and two pen notification sounds as hash-pinned, locally supplied proprietary inputs. They are intentionally ignored by Git; see prebuilt/README.md for the required identities. The product does not inherit the old GSI product or TrebleDroid to obtain those hardware components.

The panel policy exposes Standard (60 Hz), Fluid (content-aware 60–120 Hz), and Force 120 Hz modes. Fluid keeps the framework default render ceiling at 120 Hz so SurfaceFlinger's touch/content policy can select both physical modes; the user's peak and minimum settings provide the Standard and Force 120 clamps.

Pure Pixel also integrates LineageOS Aperture and Updater plus Evolution-X FaceUnlock. R6 retains Aperture source commit de12d69e0ffc and labels it Camera in the launcher. The updater is adapted to generate and install signed full recovery packages on active slot A; it does not use Android's A/B payload engine, prepare slot B, or replace retained Lenovo partitions. Face Unlock is exposed as a convenience biometric and is not a substitute for a PIN or a hardware-backed strong biometric.

Double-tap-to-wake is bridged from the persistent TB132FU setting to the stock Goodix /proc/gesture_control node by init. Device policy gives that exact proc node its own SELinux type instead of granting init access to generic proc files.

This is a native TB132FU product definition; it does not depend on PHH, TrebleDroid, or gsi_release.mk. It emits only the framework-owned system, system_ext, and product images. Lenovo's existing vendor, ODM, bootloader, firmware, persist, NVRAM/NVDATA, and calibration partitions remain preserved device inputs and are outside this repository's build and flashing scope.

Source and release boundary

This repository contains the open TB132FU device integration only. Pure Pixel 17 R6 additionally uses Android platform compatibility topics, the separately published TB132FU kernel, locally supplied proprietary Lenovo payloads, and a private optional Google/Pixel package composition. The device tree alone is therefore useful for native ROM bring-up and collaboration, but is not a complete byte-for-byte Pure Pixel build manifest.

R6 retains the complete R5 Bluetooth, charging, HDMI stereo, external-display, camera, vendor-hardening, landscape startup, and AOD baseline. Its open device additions include the adaptive Pure Pixel light/dark wallpaper, standard live wallpaper feature declaration, fresh-user pen-IME opt-in policy, Android's Multiple users UI, Pixel model-service association declarations, and an explicit consumer ADB-watchdog override. The matching Google packages, boot animation, and hash-pinned proprietary audio delegate are not distributed here.

The R6 release package keeps the R3 installer geometry hotfix and uses one standard installer for both p11_pro_2gen and p11_pro_2gen_ROW_WIFI when the tablet is active on slot A. The separately guarded ROW_WIFI migration remains only for an unlocked stock p11_pro_2gen_ROW_WIFI tablet that starts on slot B; it preserves B and writes the complete matched image set only to A. R6 also accepts the known official TB132FU, TB132FU_PRC, and TB132FU_ROW fastbootd identities, retries a missed USB transport transition exactly once, and can safely resume from either supported fastboot transport. Product, unlock, slot, logical-partition, image-hash, and geometry checks remain fail-closed before writes.

The R6 release branch is purepixel17-tb132fu-r6; R5, R4, R3, R2, and R1 release refs remain available for previous releases.
