2016-03-17IB/hfi1: Improve LED beaconingEaswar Hariharan3-51/+38
The current LED beaconing code is unclear and uses the timer handler to turn off the timer. This patch simplifies the code by removing the special semantics of timeon = timeoff = 0 being interpreted as a request to turn off the beaconing.

2016-03-17IB/hfi1: Don't call cond_resched in atomic mode when sending packetsKaike Wan1-2/+5
This patch fixed the problem where the driver might reschedule in atomic mode when sending packets. This is due to the fact that the call to cond_resched() in hfi1_do_send() might occur in atomic mode and a check is required to avoid the warning message: "kernel: BUG: scheduling while atomic: swapper/2/0/0x10000100."

2016-03-17IB/hfi1: Add adaptive cacheless verbs copyDean Luick3-2/+211
The kernel memcpy is faster than a cacheless copy. However, if too much of the L3 cache is overwritten by one-time copies then overall bandwidth suffers. Implement an adaptive scheme where full page copies are tracked and if the number of unique entries are larger than a threshold, verbs will use a cacheless copy. Tracked entries are gradually cleaned, allowing memcpy to resume once the larger copies have stopped.

2016-03-10staging/rdma/hfi1: Check interrupt registers mappingKaike Wan1-0/+56
This patch tests the interrupt registers when the driver has no access to its upstream component. In this case, it is highly likely that it is running in a virtual machine (eg, Qemu-kvm guest). If the interrupt registers are not mapped properly by the virtual machine monitor, an error message will be printed and the probing will be terminated. This will help the user identify the issue. On the other hand, if the driver is running in a host or has access to its upstream component in some other VM, it will do nothing.

2016-03-10staging/rdma/hfi1: Avoid using upstream component if it is not accessibleKaike Wan2-5/+36
When the hfi1 device is assigned to a VM (eg KVM), the hfi1 driver has no access to the upstream component and therefore cannot use it to perform some operations, such as secondary bus reset. As a result, the hfi1 driver cannot perform the pcie Gen3 transition. Instead, those operation should be done in the host environment, preferrably done during the Option ROM initialization. Similarly, the hfi1 driver cannot support ASPM and tune the pcie capability under this circumstance.
