The hardware can be shared among multiple user applications. The hardware resources are allocated/freed based on the request from user application via driver IOCTLs. DRM_IOCTL_AMDXDNA_CREATE_HWCTX Allocate tile columns and create a hardware context structure to track the usage and status of the resources. A hardware context ID is returned for XDNA command execution. DRM_IOCTL_AMDXDNA_DESTROY_HWCTX Release hardware context based on its ID. The tile columns belong to this hardware context will be reclaimed. DRM_IOCTL_AMDXDNA_CONFIG_HWCTX Config hardware context. Bind the hardware context to the required resources.
