Rick Macklem [Fri, 20 Jan 2012 00:58:51 +0000 (00:58 +0000)]
Martin Cracauer reported a problem to freebsd-current@ under the
subject "Data corruption over NFS in -current". During investigation
of this, I came across an ugly bogusity in the new NFS client where
it replaced the cr_uid with the one used for the mount. This was
done so that "system operations" like the NFSv4 Renew would be
performed as the user that did the mount. However, if any other
thread shares the credential with the one doing this operation,
it could do an RPC (or just about anything else) as the wrong cr_uid.
This patch fixes the above, by using the mount credentials instead of
the one provided as an argument for this case. It appears
to have fixed Martin's problem.
This patch is needed for NFSv4 mounts and NFSv3 mounts against
some non-FreeBSD servers that do not put post operation attributes
in the NFSv3 Statfs RPC reply.

netmap-related changes:
1. correct the initialization of RDT when there is an ixgbe_init()
   while a netmap client is active. This code was previously
   in ixgbe_initialize_receive_units() but RDT is overwritten
   shortly afterwards in ixgbe_init_locked()

2. add code (not active yet) to disable CRCSTRIP while in netmap mode.
   From all evidence i could gather, it seems that when the 82599 has to
   write a data block that is not a full cache line, it first reads
   the line (64 bytes) and then writes back the updated version.
   This hurts reception of min-sized frames, which are only 60 bytes
   if the CRC is stripped: i could never get above 11Mpps
   (received from one queue) with CRCSTRIP enabled, whyle 64+4-byte
   packets reach 14.2 Mpps (the theoretical maximum).
   Leaving the CRC in gets us 14.88Mpps for 60+4 byte frames,
   (and penalizes 64+4). The min-size case is important not just because
   it looks good in benchmarks, but also because this is the size
   of pure acks.

 - Fetch ELD data, describing connected digital display device audio
capabilities. These data not really used at the moment (user is not
denied to use audio formats not supported by the device), only printed to
verbose logs. But they are useful for debugging. The fact that ELD was
received tells that HDMI link was established and video driver enabled
HDMI audio passthrough. Some old chips may not return ELD, so lack of it
is not necessary a problem.
 - Add some more points to CODEC configuration sequence:
   - For converter widgets, supporting more then two channels (HDMI/DP
     converter widgets support 8), set number of channels to handle.
   - For digital display pins (HDMI/DP) fill audio infoframe, reporting
     connected device about number of channels and speakers allocation.
   - For digital display pins (HDMI/DP) set mapping between channels seen
     by software and channels transferred via HDMI/DisplayPort.
 - Allow more audio formats, not used for analog connections because of
stereo pairs orientation, but easily applicable to HDMI/DisplayPort: 2.1,
3.0, 3.1, 4.1, 5.0, 6.0, 6.1, 7.0. That list may be filtered later using
info from ELD.
 - Disable MSI interrupts for NVIDIA HDA controllers before GT520.

At this point I can successfully play audio over HDMI from NVIDIA GT210
