It doesn't, as after hitting the magic sysrq sigterm sequence I can see
the hdsp_fifo_wait's snd_printks appear on a regular basis (looks like
120 bpm). This is not surprising as HDSP_LONG_WAIT is supposed to last
500ms. In fact the timeout should occur 24413/2/60 = circa 186 minutes
later. The code is :
for (i = 0; i < 24413; ++i) {
hdsp_write(hdsp, HDSP_fifoData, firmware_ptr[i]);
if (hdsp_fifo_wait (hdsp, 127, HDSP_LONG_WAIT)) {
snd_printk ("timeout during firmware loading\n");
return -EIO;
}
}
If hdsp_fifo_wait fails and returns -1 we go through the whole loop,
thus effectively waiting almost 3 hours.
