Thanks for clarifying. I misread the patch. The resulting function
looks clear enough with everything together.
Thanks!
I'm also interested in comments the bug in the caller, if you have looked
there...

The test that induced the failure is associated with a host SM on
the same
server during a shutdown.
There was a bug unrelated to this that made is more reproducible. So another
bug lead to this one.

. This will save a lock of s_lock in the normal case.
The observation is that the sdma descriptors will deplete at twice the rate of
txreq's, so this should be rare.

The pcie_caps default of 0x51 will set the proposed MaxPayload
and MaxReceiveReqest to 256 and 4096 respectively. The capabilities
on the root complex will be used to limit those values.

Should whatever this issue is be a general PCI fixup? Like broken MSI,
etc.
Can you point me to some details on this?
Might be nice to include what 0x51 tunes in the commit to aide other
peoole with the broken chipset :)
Isn't it necesary to check the PCI vendor as well as the devid?
Will
Does this work on systems where the broken chipset might
not be the immediate parent of the qib device (ie there are
some PCIe switches in between)?
The code figures this out at the top of routine and returns, changing nothing.
This message and any attached documents contain information
if (parent-vendor != 0x8086)
return 1;
so I guess you don't need another vendor check.
Actually, Jason is right. The vendor check you reference here is in
qib_tune_pcie_coalesce() and not the routine being patched.
A bit of background here is that the issue was
It doesn't seem to me like this has any place in the quirks thing
either. Things seem to be working properly, the MaxPayLoad of 128 is
clearly the highest the system will support correctly.

Probably the best thing to do unwind the module parameter default in 8d4548f2b
which would

Restore the module paramter default to zero with will avoid
any changes in the root complex.
