* Handle DEAD DMA transfers: * if the TX status comes up "DEAD" - reported on some Power Computing machines * we need to re-start the dbdma - but from a different physical start address * and with a different transfer length. It would get very messy to do this * with the normal dbdma_cmd blocks - we would have to re-write the buffer start * addresses each time. So, we will keep a single dbdma_cmd block which can be * fiddled with. * When DEAD status is first reported the content of the faulted dbdma block is * copied into the emergency buffer and we note that the buffer is in use. * we then bump the start physical address by the amount that was successfully * output before it died. * On any subsequent DEAD result we just do the bump-ups (we know that we are * already using the emergency dbdma_cmd). * CHECK: this just tries to "do it". It is possible that we should abandon * xfers when the number of residual bytes gets below a certain value - I can * see that this might cause a loop-forever if a too small transfer causes * DEAD status. However this is a TODO for now - we'll see what gets reported. * When we get a successful transfer result with the emergency buffer we just * pretend that it completed using the original dmdma_cmd and carry on. The * 'next_cmd' field will already point back to the original loop of blocks. */ static inline void snd_pmac_pcm_dead_xfer(struct pmac_stream *rec, volatile struct dbdma_cmd __iomem *cp) { unsigned short req, res ; unsigned int phy ; /* printk(KERN_WARNING "snd-powermac: DMA died - patching it up!
