Mesa Upstream

A6xx / A7xx — What's In This Driver

Pure Mesa main — built directly from the latest upstream commit with no source patches.

Three inline NDK r29 compatibility fixes are applied at build time:

• buffer_handle_t typedef fix (native_handle.h)
• hnd->handle void-cast fix (u_gralloc_fallback.c)
• native_buffer->handle cast fix (vk_android.c)

Targets Snapdragon 600–800 series, 7 Gen and 8 Gen 1–3 (Adreno 600–700 series).

A8xx — What's In This Driver

Same NDK r29 fixes as above, plus the following A8xx-specific changes on top of Mesa main:

Applied via tu8_kgsl_26.patch:

• u_gralloc UBWC fix — disables the gmsm magic check for Qualcomm gralloc buffer detection, which stopped working in newer gralloc versions. Without this, UBWC detection fails and you get a distorted or broken picture on screen.
• drm-shim entries — adds A810/A825/A829 to the Mesa drm-shim device table (used for offline tracing/testing, not runtime critical).

Applied via fix_a8xx_dev_info.py:

• Adds disable_gmem property to freedreno_dev_info.h — a flag that tells the driver to skip GMEM entirely for GPUs that can't use it reliably (specifically A810).
• Adds the GMEM disable check in tu_cmd_buffer.cc so A810 uses the sysmem path instead of crashing.

Applied via apply_a8xx_gpus.py:

• Adds A825 GPU entry — completely missing from mesa/main.
• Adds chip_id=0x44010000 to A810 so KGSL can identify the device.
• Adds disable_gmem = True to A810's GPU props.
• Adds chip_id=0x44030A00 and chip_id=0xffff44030A00 to A829 so additional device revisions are recognised.

Already in mesa/main (no patching needed):

UBWC 5/6 KGSL support, A830/A829/A810 base entries, A8xx magic regs, reg_size fixes, and TU_DEBUG_FLUSHALL removal are all upstreamed and included automatically.

Compared to the Original whitebelyash/mesa-tu8 Patchset

Based on patchset-head-v2. The original had 11 commits — most have since been merged into mesa/main, so this build uses only 2 of them directly:
