Comment 19 for bug 1551041

How often do the message appear in system log? (BUG 16.04 or XRUN before 14.04)

it mean the value return is larger than buffer size or the interrupt is not handled properly

static inline int vortex_adbdma_getlinearpos(vortex_t * vortex, int adbdma) { stream_t *dma = &vortex->dma_adb[adbdma]; int temp, page, delta; temp = hwread(vortex->mmio, VORTEX_ADBDMA_STAT + (adbdma << 2)); page = (temp & ADB_SUBBUF_MASK) >> ADB_SUBBUF_SHIFT; if (dma->nr_periods >= 4) delta = (page - dma->period_real) & 3; else { delta = (page - dma->period_real); if (delta < 0) delta += dma->nr_periods; } return (dma->period_virt + delta) * dma->period_bytes + (temp & (dma->period_bytes - 1)); }
