cinap_lenrek	feb92fedb1	sgi: new approach for etherseeq ... touching transmit descriptors while dma is running causes the front to fall off. new approach keeps a counter of free descriptors in the Ring structure that is incremented by txintr() when transmit completed. txintr() will clean descriptors once dma has stopped and restart dma when there are more descrtors in the chain.	2015-03-28 14:11:17 +01:00
cinap_lenrek	177cbace73	sgi: work in progress kernel for sgi mips machines (only tested with r5k indy) ... this provides basic console support using the ARC bios routines theu uartarcs driver. and has native seeq ethernet driver which was written by reading the 2ed devseq driver as i have no documentation on the hardware. mmu and trap code is based on the routerboard kernel.	2015-03-28 05:15:40 +01:00
