23cd4716b7 staging/rdma/hfi1: Allow a fair scheduling of QPs
This patch fixes the fairness issues in QP scheduling
- the timeout for cond_resched is changed to a ratio of
qp->timeout_jiffies
- workqueue_congested is used to determine if qp needs to
reschedule itself

f1bf296340 staging/rdma/hfi1: Fix for generic I2C interface
The original I2C interface was geared for QSFP accesses. Modify
the interface to behave more like a generic I2C controller such
that reads and writes can accept multi-byte offsets. Removed
reads following writes and moved reset to top level.

957558c966 staging/rdma/hfi1: Consolidate CPU/IRQ affinity support
This patch unifies the affinity support for CPU and IRQ allocations into
a single code base. The goal is to allow the driver to make intelligent
placement decision based on an overall view of processes and IRQs across
as much of the driver as possible.

Pulling all the scattered affinity code into a single code base lays the
ground work for accomplishing the above goal.  For example, previous
implementations made user process placement decision solely based on
other user processes.  This algorithm is limited as it did not take into
account IRQ placement and could result in overloading certain CPUs.

A single code base also provides a much easier way to maintain and debug
any performance issues related to affinity.

affa48de84 staging/rdma/hfi1: Add support for enabling/disabling PCIe ASPM
hfi1 HW has a high PCIe ASPM L1 exit latency and also advertises an
acceptable latency less than actual ASPM latencies. Additional
mechanisms than those provided by BIOS/OS are therefore required to
enable/disable ASPM for hfi1 to provide acceptable power/performance
trade offs. This patch adds this support.

By means of a module parameter ASPM can be either (a) always enabled
(power save mode) (b) always disabled (performance mode) (c)
enabled/disabled dynamically. The dynamic mode implements two
heuristics to alleviate possible problems with high ASPM L1 exit
latency. ASPM is normally enabled but is disabled if (a) there are any
active user space PSM contexts, or (b) for verbs, ASPM is disabled as
interrupt activity for a context starts to increase.

A few more points about the verbs implementation. In order to reduce
lock/cache contention between multiple verbs contexts, some processing
is done at the context layer before contending for device layer
locks. ASPM is disabled when two interrupts for a context happen
within 1 millisec. A timer is scheduled which will re-enable ASPM
after 1 second should the interrupt activity cease. Normally, every
interrupt, or interrupt-pair should push the timer out
further. However, since this might increase the processing load per
interrupt, pushing the timer out is postponed for half a second. If
after half a second we get two interrupts within 1 millisec the timer
is pushed out by another second.

Finally, the kernel ASPM API is not used in this patch. This is
because this patch does several non-standard things as SW workarounds
for HW issues. As mentioned above, it enables ASPM even when advertised
actual latencies are greater than acceptable latencies. Also, whereas
the kernel API only allows drivers to disable ASPM from driver probe,
this patch enables/disables ASPM directly from interrupt context. Due
to these reasons the kernel ASPM API was not used.

566c157cbd staging/rdma/hfi1: Correctly set RcvCtxtCtrl register
The RcvCtxtCtrl register was being incorrectly set upon context
initialization and clean up resulting, in many cases, of contexts using
settings from previous contexts' initialization. This resulted in bad
and unexpected behavior. This was especially important for the TailUpd
bit, which requires special handling and if set incorrectly could lead
to severely degraded performance.

This patch fixes the handling of the RcvCtxtCtrl register, ensuring that
each context gets initialized with settings applicable only for that
context. It also ensures the proper setting for the TailUpd bit by
setting it to either 0 or 1 (as needed by the context's configuration)
explicitly.

8ebd4cf185 staging/rdma/hfi1: Add active and optical cable support
This patch qualifies and tunes active and optical cables for optimal
bit error rate and signal integrity settings. These settings are

Based on attributes of the QSFP cable as read from the SFF-8636
compliant memory map, we select the appropriate settings from the
platform configuration data (examples: TX/RX equalization, enabling
cable high power, enabling TX/RX clock data recovery mechanisms, and RX
amplitude control) and apply them to the SERDES and QSFP cable.

The platform configuration data also contains system parameters such
as maximum power dissipation supported, and the cables are qualified
based on these parameters. As part of qualifying the cables, the
correct OfflineDisabledReasons are set for the appropriate scenarios.

a9c05e350c staging/rdma/hfi1: HFI reports wrong offline disabled reason when cable removed
Removing QSFP cable should report 'No Local Media' instead of
'Transient' as reported by 'opaportinfo'.
Workaround is to change the state to
OPA_LINKDOWN_REASON_LOCAL_MEDIA_NOT_INSTALLED in cable handler.

With cable still removed, 'opaportinfo bounce' should not cause a
state change to Polling, as reported by 'opaportinfo'.
Resolution is to prevent physical state change from Offline->Polling.

Use a macro to mask lower nibble of OPA_LINKDOWN_REASON* as needed
for offline_disabled_reason.

which holds the queue pair numbers in favor of using what is provided
by rdmavt.

done in rdmavt. Remove support from hfi1. The allocation and
maintenance of the list still resides in the driver.

895420ddc8 staging/rdma/hfi1: Remove hfi1 MR and hfi1 specific qp type
This patch does the actual removal of the queue pair from the hfi1 driver
along with a number of dependent data structures. These were moved to rvt.

It also removes the MR functions to use those in rdmavt.

These two pieces can not reasonably be split apart becuase they depend on
each other.
