2017-05-05IB/hfi1: Clean up on context initialization failureMichael J. Ruhl1-6/+4
The error path for context initialization is not consistent. Cleanup all resources on failure. Removed unused variable user_event_mask. Add the _BASE_FAILED bit to the event flags so that a base context can notify waiting sub contexts that they cannot continue. Running out of sub contexts is an EBUSY result, not EINVAL.

2017-05-05IB/hfi1: Fix an assign/ordering issue with shared context IDsMichael J. Ruhl1-1/+2
The current algorithm for generating sub-context IDs is FILO. If the contexts are not closed in that order, the uniqueness of the ID will be compromised. I.e. logging the creation/deletion of context IDs with an application that assigns and closes in a FIFO order reveals: cache_id: assign: uctxt: 3 sub_ctxt: 0 cache_id: assign: uctxt: 3 sub_ctxt: 1 cache_id: assign: uctxt: 3 sub_ctxt: 2 cache_id: close: uctxt: 3 sub_ctxt: 0 cache_id: assign: uctxt: 3 sub_ctxt: 2 <<< The sub_ctxt ID 2 is reused incorrectly. Update the sub-context ID assign algorithm to use a bitmask of in_use contexts. The new algorithm will allow the contexts to be closed in any order, and will only re-use unused contexts. Size subctxt and subctxt_cnt to match the user API size. Reviewed-by: Mike Marciniszyn <mike.marciniszyn@intel.com> Signed-off-by: Michael J.

2017-05-05IB/hfi1: Clean up context initializationMichael J. Ruhl1-8/+2
Context initialization mixes base context init with sub context init. This is bad because contexts can be reused, and on reuse, reinit things that should not re-initialized. Normalize comments and function names to refer to base context and sub context (not main, shared or slaves). Separate the base context initialization from sub context initialization. hfi1_init_ctxt() cannot return an error so changed to a void and remove error message.

2017-05-05IB/hfi1: Fix yield logic in send engineMike Marciniszyn1-1/+2
When there are many RC QPs and an RDMA READ request is sent, timeouts occur on the requester side because of fairness among RC QPs on their relative SDMA engine on the responder side. This also hits write and send, but to a lesser extent. Complicating the issue is that the current code checks if workqueue is congested before scheduling other QPs, however, this check is based on the number of active entries in the workqueue, which was found to be too big to for workqueue_congested() to be effective. Fix by reducing the number of active entries as revealed by experimentation from the default of num_sdma to HFI1_MAX_ACTIVE_WORKQUEUE_ENTRIES. Retry counts were monitored to determine the correct value. Tracing to investigate any future issues is also added.

In the function hfi1_create_ctxts the array "dd->rcd" is allocated and then populated with allocated resources in a loop. Previously, if error happened during the loop, only resource allocated in the current iteration would be freed. The array itself would then be freed, leaving the resources that were allocated in previous iterations and referenced by the array elements in limbo. This patch makes sure all allocated resources are freed before freeing the array "dd->rcd". Also the resource allocation now takes account of the numa node the device is attached to.

2016-09-02IB/hfi1: Make n_krcvqs be an unsigned long integerHarish Chegondi1-1/+1
The global variable n_krcvqs stores the sum of the number of kernel receive queues of VLs 0-7 which the user can pass to the driver through the module parameter array krcvqs which is of type unsigned integer. If the user passes large value(s) into krcvqs parameter array, it can cause an arithmetic overflow while calculating n_krcvqs which is also of type unsigned int. The overflow results in an incorrect value of n_krcvqs which can lead to kernel crash while loading the driver. Fix by changing the data type of n_krcvqs to unsigned long.

2016-08-02IB/hfi1: Reserve and collapse CPU cores for contextsSebastian Sanchez1-2/+4
Kernel receive queues oversubscribe CPU cores on multi-HFI systems. To prevent this, the kernel receive queues are separated onto different cores, and the SDMA engine interrupts are constrained to a lesser number of cores. hfi1s_on_numa_node*krcvqs is the number of CPU cores that are reserved for kernel receive queues for all HFIs. Each HFI initializes its kernel receive queues to one of the reserved CPU cores. If there ends up being 0 CPU cores leftover for SDMA engines, use the same CPU cores as receive contexts. In addition, general and control contexts are assigned to their own CPU core, however, both types of contexts tend to have low traffic. To save CPU cores, collapse general and control contexts to one CPU core for all HFI units. This change prevents SDMA engine interrupts from wrapping around general contexts.

2016-08-02IB/hfi1: Add global structure for affinity assignmentsDennis Dalessandro1-1/+4
When HFI units get initialized, they each use their own mask copy for affinity assignments. On a multi-HFI system, affinity assignments overbook CPU cores as each HFI doesn't have knowledge of affinity assignments for other HFI units. Therefore, some CPU cores are never used for interrupt handlers in systems with high number of CPU cores per NUMA node. For multi-HFI systems, SDMA engine interrupt assignments start all over from the first CPU in the local NUMA node after the first HFI initialization. This change allows assignments to continue where the last HFI unit left off. Add global structure for affinity assignments for multiple HFIs to share affinity mask.
