- don't uselessly initialize the fifo "DMA" bit at attach time. - initialize the fifo "DMA" bit at open time. Without this, the device interrupts for every character received, reducing input performance to that of an 8250. - don't uselessly initialize the fifo trigger level to 8 (scaled to 256) at attach time. - don't scale the fifo trigger level to 512 bytes. The driver's pseudo- dma buffer has size 256, so it can't handle bursts of size 512 or 256. It should be able to handle the second lowest ftl (2 scaled to 64). - don't reset the fifos in siostop(). Reset triggers a hardware bug involving wedging of the output interrupt bit This workaround unfortunately requires ESP support to be configured. |
