## Overview

This is the Linux kernel: a monolithic operating-system kernel providing architecture support, device drivers, filesystems, and shared runtime services. The supplied tree spans many unrelated kernel areas, so the graph presents selected substantial subsystems rather than implying a single end-to-end request pipeline. Shown relationships are limited to explicit source-index references or excerpted includes; most subsystem internals and their runtime wiring were not sampled.

Main entry points: [`drivers/crypto/qat/qat_common/adf_accel_engine.c`](https://github.com/manish4586/android_kernel_xiaomi_jasmine_sprout/blob/Q-4.14/drivers/crypto/qat/qat_common/adf_accel_engine.c) (QAT firmware engine), [`drivers/crypto/ccp/ccp-dmaengine.c`](https://github.com/manish4586/android_kernel_xiaomi_jasmine_sprout/blob/Q-4.14/drivers/crypto/ccp/ccp-dmaengine.c) (CCP DMA driver), [`drivers/gpu/drm/i915/intel_engine_cs.c`](https://github.com/manish4586/android_kernel_xiaomi_jasmine_sprout/blob/Q-4.14/drivers/gpu/drm/i915/intel_engine_cs.c) (i915 engine runtime), [`include/linux/dmaengine.h`](https://github.com/manish4586/android_kernel_xiaomi_jasmine_sprout/blob/Q-4.14/include/linux/dmaengine.h) (DMA engine API)
