WinNative Turnip Drivers

A unified Turnip Vulkan driver build for all Adreno GPUs on Android, packaged as Adrenotools-compatible .zip archives. The build script always pulls upstream Mesa main, applies the patches in patches/, and produces two flavours of the same libvulkan_freedreno.so.

Variants

Variant	File	Tuning
Balanced	WN-Turnip-<version>-b_Axxx.zip	Slightly relaxed GMEM autotuner. Standard KGSL power management. Best for most games and battery life.
Performance	WN-Turnip-<version>-p_Axxx.zip	Aggressive GMEM autotuner. Forces KGSL_PROP_PWR_CONSTRAINT = PWR_MAX at queue creation and re-asserts it every 1000 submissions to keep the GPU at top clocks. Higher framerate, higher power draw.

Each archive ships:

libvulkan_freedreno.so
meta.json

Supported GPUs

A single driver covers the full Adreno line:

• A6xx — A6xx series (e.g. A640 / A650 / A660)
• A7xx
  • gen1 — A720 / A725 / A730 (preamble + scalar-predicate quirks applied)
  • gen2 — FD740 / Adreno X1-85 (UBWC hint applied to fix UI corruption)
  • gen3 — A750 and later
• A8xx — A810 / A825 / A829 / A830 / A840 (and X2-85)
  • A810 / A829 boot with disable_gmem so they fall back to sysmem rendering (broken GMEM on those parts).
  • A825 (not yet upstream) is added with corrected tile geometry and depth-cache layout.
  • A830 / A840 / X2-85 use the upstream profiles unchanged.

Features

• Always built from upstream Mesa main — every run re-clones, re-patches, re-builds. No pinned forks.
• Per-chip disable_gmem GPU property plumbed through freedreno_dev_info.h and tu_cmd_buffer.cc for parts with broken GMEM.
• KGSL UBWC gralloc detection bypass (newer Qualcomm gralloc no longer writes the legacy gmsm magic header).
• A8xx UE5 / VKD3D-Proton SM6.6 freeze workaround — EXT_shader_image_atomic_int64 advertisement disabled while upstream resolves the underlying 64-bit image atomic implementation.
• Adrenotools-compatible meta.json with simple WN-<version>-<variant> driver versioning.

Build

Requirements:

• Linux host (Ubuntu / Debian recommended)
• git, meson, ninja, patchelf, unzip, curl, pip, flex, bison, zip, glslang / glslangValidator
• Python with mako
• Android NDK r26d (the script expects it at /home/max/Build/Turnip/android-ndk-r26d — edit build_turnip.sh to point at your NDK)

./build_wn_turnip.sh

Outputs both variants as WN-Turnip-<version>-{b,p}_Axxx.zip in the project root.

Install on device

Adrenotools-aware launchers (e.g. WinNative, Winlator) can import each .zip directly:

Container → Edit → Graphics Driver → Import driver → pick the .zip → save → relaunch.
