Function Description

Table 1 lists interfaces provided by KUAF.

**Table 1** KUAF interfaces
Interface	Description
kuaf_ctx_scheduler_create	Creates a ctx structure according to the algorithm type and algorithm ID.
kuaf_ctx_scheduler	Acts as a unified interface at the decision-making layer. It obtains information about the algorithm required by the service and invokes the configuration file module to read configuration files. Then, according to the configured scheduling policy, it invokes bandwidth-based scheduling or ratio-based scheduling, and records scheduling decision-making information in the ctx structure.
kuaf_ctx_scheduler_free	Releases the structure resource.
kuaf_ctx_process_sync	Acts as a unified interface of the execution module. It distributes execution code downwards and calls the hardware or software computing interfaces of the algorithm based on information in the ctx structure.
kuaf_ctx_end_process	Performs post-processing after kuaf_ctx_process_sync.

KUAF is available on the Kunpeng platform only. To achieve better performance, complete input parameter verification is not performed in KUAF interfaces. Use valid input parameters, and invalid input parameters may cause errors.
When writing a user-defined function, you are advised to avoid using "kuaf" as the naming prefix to prevent link conflicts caused by name collision with the global symbol.
In decompression scenarios where the size of raw data is unknown, you are advised to use the streaming decompression mode. If block-based decompression is required, you need to estimate the data size and allocate a target buffer with sufficient space. Otherwise, decompression operations will trigger undefined behavior when the target buffer space is insufficient, resulting in unpredictable program execution results.
