* IB/ipath: Prevent link-recovery code from negating admin disableMichael Albaugh2008-04-161-0/+1
| | | | | | | | | | | The link can be put in LINKDOWN_DISABLE state either locally or via a MAD. However, the link-recovery code will take it out of that state as a side-effect of attempts to clear SerDes/XGXS issues. We add a flag to indicate "link is down on purpose, leave it alone."

* IB/ipath: Head of Line blocking vs forward progress of user appsJohn Gregor2008-04-161-0/+1
| | | | | | | | | | | | | | | | There's a conflict between our need to quiesce PSM-based applications to avoid HoL blocking when the IB link goes down and the apps' desire to remain running so that their quiescence timout mechanism can keep running. The compromise is to STOP the processes for a fixed period of time and then alternate between CONT and STOP until the link is again active. If there are poor interactions with subnet manager configuration at a given site, the interval can be adjusted via a module paramter.

* IB/ipath: Change packet problems vs chip errors handling and reportingBryan O'Sullivan2007-04-181-0/+1
| | | | | | | | | | | | | | | Some types of packet errors are moderately common with longer IB cables and large clusters, and are not reported with prints by other IB HCA drivers. This suppresses those messages unless the new __IPATH_ERRPKTDBG bit is set in ipath_debug. Reporting of temporarily disabled frequent error interrupts was also made clearer We also distinguish between chip errors, and bad packets sent or received in the wording of the messages.

* IB/ipath: remove stale references to userspace SMABryan O'Sullivan2006-09-221-2/+0
| | | | | | | | | When we first submitted a userspace subnet management agent, it was rejected, so we left it out of the final driver submission. This patch removes a number of vestigial references to it. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB/ipath: core driver header filesBryan O'Sullivan2006-03-311-0/+96
ipath_common.h and ips_common.h contain definitions shared between userspace and the kernel. ipath_kernel.h is the core driver header file. ipath_debug.h contains mask values used for controlling driver debugging. ipath_registers.h contains bitmask definitions used in chip registers.
