Date: Sat, 07 Nov 2026 13:39:56 +0000 [thread overview]

In-Reply-To: <20261107133027.364237-6-den@valinux.co.jp>
> While HDMA is running, DMA_LLP is updated only at watermark events.
> Enable watermark interrupts to track progress without waiting for the
> channel to stop.
>
> Set the watermark bits on entries that request an interrupt, configure
> local or remote delivery, and pass events to the LL progress handler.
> Unmask local watermark interrupts only for LL channels in local IRQ mode.
