Use flexcan's 6 mailbox deep hardware FIFO. Vf610 SoCs can make use of the 64 mailbox software FIFO, while older SoCs still The remaining patches modify the flexcan driver to make use of it. Sorted by timestamp in IRQ context, sending is done later in NAPI aswell. The second one requires mailboxes with timestamps. The first one is for hardware FIFO based cores, like the flexcan in FIFO mode. The first two patches add each an offloading scheme. This patch takes up the idea to read the CAN frames in IRQ context and send ` (15 more replies) 0 siblings, 16 replies 30+ messages in threadįrom: Marc Kleine-Budde 18:32 UTC ( / raw) 18:32 ` can: rx-offload: Add support for HW fifo based irq offloading Marc Kleine-Budde Can: rx-offload: add implmentation and switch flexcan driver to use it All of help / color / mirror / Atom feed * can: rx-offload: add implmentation and switch flexcan driver to use it 18:32 Marc Kleine-Budde
