- Introduced to define the development environment and validate runtime/platform contracts. - Enhanced with to ensure change markers adhere to publication rules. - Updated to integrate boot acceptance checks and ensure dependencies are correctly managed. - Added tests for environment validation, publication change scope, and CI stages to prevent regression and ensure compliance with publication standards. - Implemented checks in to validate the presence of development environment dependencies. - Refactored existing tests to improve coverage and ensure accurate validation of publication claims and software configurations.

*Ten resources* are managed: central DMA, USB2, SDIO0, SDIO1, SPI-SD, EXT-H, JPEG,
|
|
APU, GA2D and NPU. Resource ABI 1.2 reports ten slots. Resource 9 owns the native-HP
|
|
NPU, including LP vector 33 / HP PLIC 12 steering. Resource 8 routes the GA2D
|
|
its IRQ according to its current owner and controls its private AXI64 lifecycle.
|
|
GA2D supports FILL, COPY, bit-exact CONVERT, opaque alpha BLEND, A8 fixed-color
|
|
foreground masks, and exact equal background/destination in-place composition.
|
|
RGB565, RGB888, XRGB8888, and ARGB8888 are color surfaces; A8 is BLEND
|
|
foreground-only. Snapshots, pitch, and byte edges remain available. It does not
|
|
provide transparent-background/premultiplied-alpha modes, scaling, rendering,
|
|
descriptor/ring/queue submission, hardware cache coherency, or a Linux graphics driver.
|
|
Ownership changes require *quiesce, completion of accepted traffic and cache-maintenance
|
|
handoff*. HP can inspect allowed status but *cannot take over root writes*. An ownership grant
|
|
does not bypass the target access policy or EXT-H address bounds.

See @npu for descriptor execution and the distinction between coordinated clock pause,

resource quiesce and cancellation/drain.
