The HAL Overview page says:
"Some HAL driver's may have slightly different behavior when run in an RTOS environment. This is typically found in operations that need to wait for a significant period of time. In an RTOS aware environment, the function will attempt to wait using the RTOS." .. "To inform the HAL that an RTOS environment is being used the RTOS_AWARE component (COMPONENTS+=RTOS_AWARE) or the CY_RTOS_AWARE define (DEFINES+=CY_RTOS_AWARE) must be set. When set, the HAL will use the RTOS Abstraction APIs to wait."
Wanting to understand this more specifically, I looked for how it was implemented. But I only find a definition of a delay function, and not many usages of it.

Did the roadmap make it to the documentation before the code?
I am more concerned with freeing the CPU gracefully for I2C, SPI, and I2S operations. But in cyhal_spi.c I see concerning time sinks like
while (Cy_SCB_SPI_IsTxComplete(obj->base) == false) { }
Is it even advisable to use HAL functions with an RTOS and tickless idle if we are concerned about power consumption?
