A driver which supports hardware time stamping must support the
SIOCSHWTSTAMP ioctl. Time stamps for received packets must be stored
in the skb with skb_hwtstamp_set().
SIOCSHWTSTAMP ioctl and update the supplied struct hwtstamp_config with
the actual values as described in the section on SIOCSHWTSTAMP.
Time stamps for received packets must be stored in the skb. To get a pointer
to the shared time stamp structure of the skb call skb_hwtstamps(). Then
set the time stamps in the structure:
struct skb_shared_hwtstamps {
/* hardware time stamp transformed into duration
* since arbitrary point in time
*/
ktime_t hwtstamp;
ktime_t syststamp; /* hwtstamp transformed to system time base */
};
Time stamps for outgoing packets are to be generated as follows:
- In hard_start_xmit(), check if skb_hwtstamp_check_tx_hardware()
returns non-zero. If yes, then the driver is expected
to do hardware time stamping.
- In hard_start_xmit(), check if skb_tx(skb)->hardware is set no-zero.
If yes, then the driver is expected to do hardware time stamping.
- If this is possible for the skb and requested, then declare
that the driver is doing the time stamping by calling
skb_hwtstamp_tx_in_progress(). A driver not supporting
hardware time stamping doesn't do that. A driver must never
touch sk_buff::tstamp! It is used to store how time stamping
for an outgoing packets is to be done.
that the driver is doing the time stamping by setting the field
skb_tx(skb)->in_progress non-zero. You might want to keep a pointer
to the associated skb for the next step and not free the skb. A driver
not supporting hardware time stamping doesn't do that. A driver must
never touch sk_buff::tstamp! It is used to store software generated
time stamps by the network subsystem.
- As soon as the driver has sent the packet and/or obtained a
hardware time stamp for it, it passes the time stamp back by
calling skb_hwtstamp_tx() with the original skb, the raw
hardware time stamp and a handle to the device (necessary
to convert the hardware time stamp to system time). If obtaining
the hardware time stamp somehow fails, then the driver should
not fall back to software time stamping. The rationale is that
this would occur at a later time in the processing pipeline
than other software time stamping and therefore could lead
to unexpected deltas between time stamps.
- If the driver did not call skb_hwtstamp_tx_in_progress(), then
hardware time stamp. skb_hwtstamp_tx() clones the original skb and
adds the timestamps, therefore the original skb has to be freed now.

Interrupt Handling
~~~~~~~~~~~~~~~~~~
In rare but some cases, the interrupt isn't properly handled as
default. You would notice this by the DMA transfer error reported by
ALSA PCM core, for example. Using MSI might help in such a case.
Pass `enable_msi=1` option for enabling MSI.
HD-audio driver uses MSI as default (if available) since 2.6.33
kernel as MSI works better on some machines, and in general, it's
better for performance. However, Nvidia controllers showed bad
regressions with MSI (especially in a combination with AMD chipset),
thus we disabled MSI for them.
There seem also still other devices that don't work with MSI. If you
see a regression wrt the sound quality (stuttering, etc) or a lock-up
in the recent kernel, try to pass `enable_msi=0` option to disable
MSI. If it works, you can add the known bad device to the blacklist
defined in hda_intel.c. In such a case, please report and give the
patch back to the upstream developer.
