| _florent__ | futarisIRCcloud: i'm looking that that, i'll probably merge it, and we'll then have to figure out what's the problem with the interrupts | 08:07 |
|---|---|---|
| futarisIRCcloud | Ok | 08:26 |
| daveshah | The problem with the interrupts is that Linux doesn't know about the VexRiscv specific CSRs | 08:31 |
| daveshah | Either we could implement/emulate a PLIC or add a driver for the VexRiscv IRQ suppory | 08:32 |
| daveshah | This could be based on the one from the old kernel, but with a different CSR number: https://github.com/daveshah1/litex-linux-riscv/blob/master/drivers/irqchip/irq-vex.c | 08:33 |

| sorear | what's the status/plans with DMA and coherence btw? | 08:40 |
| _florent__ | sorear: DMA for LiteETH? i yes, we first want to get the current version working, identify the bottlenecks and then add DMA (ambro718 is working on implementing DMA) | 10:52 |
