* IB/hfi1: Move driver out of stagingDennis Dalessandro2016-05-261-1145/+0
| | | | | | | | | | | The TODO list for the hfi1 driver was completed during 4.6. In addition other objections raised (which are far beyond what was in the TODO list) have been addressed as well. It is now time to remove the driver from staging and into the drivers/infiniband sub-tree.

| | | | | | | | | | | | Different OSes using parts of the same hardware may leave cross-device flags set. Export a debugfs file to view and clear these flags if needed.

| | | | | | | | | | | | External i2c firmware updates are done in multiple steps and cannot have other things done in between. For debugfs files, acquire the resource on open and release it on close.

* IB/hfi1: Change QSFP functions to use resource reservationDean Luick2016-03-171-5/+17
| | | | | | | | | | | | | Remove the mutex guarding each operation in favor the ASIC resource acquire/release. Push the resource acquire/release, above each operation call to allow exclusive access across multiple operations.

* staging/rdma/hfi1: Fix counter read for cpDean Luick2016-03-101-7/+4
| | | | | | | | | | | | | | | | | | | A cp or cat of /sys/kernel/debug/hfi1/hfi1_0/port1counters produces the following message: hfi1 0000:81:00.0: hfi1_0: index not supported hfi1 0000:81:00.0: hfi1_0: read_cntrs does not support indexing Fix by removing the file position logic and the associated messages and make the file positioning the responsibility of the caller. The port counter read function argument is changed to the per port data structure since the counters are relative to the port and not the device.
