2016-10-11kthread: kthread worker API cleanupPetr Mladek
A good practice is to prefix the names of functions by the name of the subsystem. The kthread worker API is a mix of classic kthreads and workqueues. Each worker has a dedicated kthread. It runs a generic function that process queued works. It is implemented as part of the kthread subsystem. This patch renames the existing kthread worker API to use the corresponding name from the workqueues API prefixed by kthread_: __init_kthread_worker() -> __kthread_init_worker() init_kthread_worker() -> kthread_init_worker() init_kthread_work() -> kthread_init_work() insert_kthread_work() -> kthread_insert_work() queue_kthread_work() -> kthread_queue_work() flush_kthread_work() -> kthread_flush_work() flush_kthread_worker() -> kthread_flush_worker() Note that the names of DEFINE_KTHREAD_WORK*() macros stay as they are. It is common that the "DEFINE_" prefix has precedence over the subsystem names. Note that INIT() macros and init() functions use different naming scheme. There is no good solution. There are several reasons for this solution: + "init" in the function names stands for the verb "initialize" aka "initialize worker". While "INIT" in the macro names stands for the noun "INITIALIZER" aka "worker initializer". + INIT() macros are used only in DEFINE() macros + init() functions are used close to the other kthread() functions. It looks much better if all the functions use the same scheme. + There will be also kthread_destroy_worker() that will be used close to kthread_cancel_work(). It is related to the init() function. Again it looks better if all functions use the same naming scheme. + there are several precedents for such init() function names, e.g. amd_iommu_init_device(), free_area_init_node(), jump_label_init_type(), regmap_init_mmio_clk(), + It is not an argument but it was inconsistent even before.

2016-10-07iw_cxgb4: add fast-path for small REG_MR operationsSteve Wise
When processing a REG_MR work request, if fw supports the FW_RI_NSMR_TPTE_WR work request, and if the page list for this registration is <= 2 pages, and the current state of the mr is INVALID, then use FW_RI_NSMR_TPTE_WR to pass down a fully populated TPTE for FW to write. This avoids FW having to do an async read of the TPTE blocking the SQ until the read completes. To know if the current MR state is INVALID or not, iw_cxgb4 must track the state of each fastreg MR. The c4iw_mr struct state is updated as REG_MR and LOCAL_INV WRs are posted and completed, when a reg_mr is destroyed, and when RECV completions are processed that include a local invalidation. This optimization increases small IO IOPS for both iSER and NVMF. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

2016-10-07IB/mlx4: Fix possible vl/sl field mismatch in LRH header in QP1 packetsJack Morgenstein
In MLX qp packets, the LRH (built by the driver) has both a VL field and an SL field. When building a QP1 packet, the VL field should reflect the SLtoVL mapping and not arbitrarily contain zero (as is done now). This bug causes credit problems in IB switches at high rates of QP1 packets. The fix is to cache the SL to VL mapping in the driver, and look up the VL mapped to the SL provided in the send request when sending QP1 packets. For FW versions which support generating a port_management_config_change event with subtype sl-to-vl-table-change, the driver uses that event to update its sl-to-vl mapping cache. Otherwise, the driver snoops incoming SMP mads to update the cache. There remains the case where the FW is running in secure-host mode (so no QP0 packets are delivered to the driver), and the FW does not generate the sl2vl mapping change event. To support this case, the driver updates (via querying the FW) its sl2vl mapping cache when running in secure-host mode when it receives either a Port Up event or a client-reregister event (where the port is still up, but there may have been an opensm failover). OpenSM modifies the sl2vl mapping before Port Up and Client-reregister events occur, so if there is a mapping change the driver's cache will be properly updated.

Jake fixes an issue where PTP applications requesting software timestamps may complain that the requested mode is not supported, so add a generic callback for those drivers that have software transmit timestamp support enabled. Then provides a trivial cleanup where a code was not wrapped properly. Got make sure that code looks good in a 80 character limit. ==================== Signed-off-by: David S.

2016-10-03i40e: avoid NULL pointer dereference and recursive errors on early PCI errorGuilherme G Piccoli
Although rare, it's possible to hit PCI error early on device probe, meaning possibly some structs are not entirely initialized, and some might even be completely uninitialized, leading to NULL pointer dereference. The i40e driver currently presents a "bad" behavior if device hits such early PCI error: firstly, the struct i40e_pf might not be attached to pci_dev yet, leading to a NULL pointer dereference on access to pf->state. Even checking if the struct is NULL and avoiding the access in that case isn't enough, since the driver cannot recover from PCI error that early; in our experiments we saw multiple failures on kernel log, like: [549.664] i40e 0007:01:00.1: Initial pf_reset failed: -15 [549.664] i40e: probe of 0007:01:00.1 failed with error -15 [...] [871.644] i40e 0007:01:00.1: The driver for the device stopped because the device firmware failed to init. Try updating your NVM image. [871.644] i40e: probe of 0007:01:00.1 failed with error -32 [...] [872.516] i40e 0007:01:00.0: ARQ: Unknown event 0x0000 ignored Between the first probe failure (error -15) and the second (error -32) another PCI error happened due to the first bad probe. Also, driver started to flood console with those ARQ event messages. This patch will prevent these issues by allowing error recovery mechanism to remove the failed device from the system instead of trying to recover from early PCI errors during device probe.

Stefan Assmann provides the changes in this series to resolve an issue where when we run out of MSIx vectors, iWARP gets disabled automatically. First adds a check for "no vectors left" during MSIx vector allocation for VMDq, which will prevent more vectors being allocated than available. Then fixed the MSIx vector redistribution when we reach the hardware limit for vectors so that additional features like VMDq, iWARP, etc do not get starved for vectors because the PF is hogging all the resources. Lastly, fix the issue for flow director by moving the check for the reaching the vector limit earlier in the code so that a decision can be made on disabling flow director. ==================== Signed-off-by: David S.
