RTOS/OMAP-L138: Using Swi_post() inside a zero-latency hwi (hwi_plug)

Part Number: OMAP-L138

Tool/software: TI-RTOS

We are using OMAP-l138 and it seems DSP is missing some gpio interrupts when arm is performing a file write. We use linux on Arm and sys/bios with Syslink on DSP. We want to catch the gpio interrupts on DSP in zero latency mode and handle them later on a Swi. However according to documentation it is not recommended to use Swi_post() api inside the zero latency handler. I am curious to know whether there is a way to do this. because we need the DSP not to miss the interrupt. Thanks in advance
