net/mlx5_core: Use coherent memory for command interface page

2015-04-02T20:33:41Z

Use coherent memory for the commands descriptor page. Take measures to make sure the page is aligned to MLX5_ADAPTER_PAGE_SIZE as required by the hardware. Reported-by: Yevgeny Kliteynik Signed-off-by: Eli Cohen Signed-off-by: Saeed Mahameed Signed-off-by: David S. Miller

IB/mlx5: Handle page faults

2014-12-16T02:19:03Z

This patch implement a page fault handler (leaving the pages pinned as of time being). The page fault handler handles initiator and responder page faults for UD/RC transports, for send/receive operations, as well as RDMA read/write initiator support.

IB/mlx5: Page faults handling infrastructure

2014-12-16T02:19:03Z

* Refactor MR registration and cleanup, and fix reg_pages accounting. * Create a work queue to handle page fault events in a kthread context. * Register a fault handler to get events from the core for each QP. The registered fault handler is empty in this patch, and only a later patch implements it.

IB/mlx5: Add mlx5_ib_update_mtt to update page tables after creation

2014-12-16T02:19:02Z

The new function allows updating the page tables of a memory region after it was created. This can be used to handle page faults and page invalidations. Since mlx5_ib_update_mtt will need to work from within page invalidation, so it must not block on memory allocation. It employs an atomic memory allocation mechanism that is used as a fallback when kmalloc(GFP_ATOMIC) fails. In order to reuse code from mlx5_ib_populate_pas, the patch splits this function and add the needed parameters. Signed-off-by: Haggai Eran Signed-off-by: Shachar Raindel Signed-off-by: Roland Dreier

IB/mlx5: Changes in memory region creation to support on-demand paging

2014-12-16T02:19:02Z

This patch wraps together several changes needed for on-demand paging support in the mlx5_ib_populate_pas function, and when registering memory regions. * Instead of accepting a UMR bit telling the function to enable all access flags, the function now accepts the access flags themselves. * For on-demand paging memory regions, fill the memory tables from the correct list, and enable/disable the access flags per-page according to whether the page is present. * A new bit is set to enable writing of access flags when using the firmware create_mkey command. * Disable contig pages when on-demand paging is enabled. In addition the patch changes the UMR code to use PTR_ALIGN instead of our own macro. Signed-off-by: Haggai Eran Signed-off-by: Roland Dreier

mlx5_core: Add support for page faults events and low level handling

2014-12-16T02:18:59Z

* Add a handler function pointer in the mlx5_core_qp struct for page fault events. Handle page fault events by calling the handler function, if not NULL. * Add on-demand paging capability query command. * Export command for resuming QPs after page faults. * Add various constants related to paging support.
