Mesa Upstream

What's In This Driver

Base: Mesa main + A8xx-specific patches. All variants share:

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.
• drm-shim entries — adds A810/A825/A829 to the Mesa drm-shim device table.

Applied via fix_a8xx_dev_info.py:

• Adds disable_gmem property to freedreno_dev_info.h — tells the driver to skip GMEM for A810.
• Adds the GMEM disable check in tu_cmd_buffer.cc.

Applied via apply_a8xx_gpus.py:

• Adds A825 GPU entry — completely missing from mesa/main.
• Adds chip_id=0x44010000 to A810 for KGSL.
• Adds disable_gmem = True to A810.
• Adds extra chip IDs to A829 for additional device revisions.
