RDMA/ocrdma: Don't inline statistics functions

2024-07-11T10:25:11Z

Fix the problem of KASAN causing the stack frame size to increase drivers/infiniband/hw/ocrdma/ocrdma_stats.c:686:16: error: stack frame size (20664) exceeds limit (8192) in 'ocrdma_dbgfs_ops_read' [-Werror,-Wframe-larger-than] static ssize_t ocrdma_dbgfs_ops_read(struct file *filp, char __user *buffer, ^ Some functions called by ocrdma_dbgfs_ops_read occupy a lot of stack space. Mark these functions as noinline_for_stack to prevent them from accumulating in ocrdma_dbgfs_ops_read.

RDMA/ocrdma: Fix spelling mistake in variable name

There is a spelling mistake in the variable nak_invalid_requst_errors, rename it to nak_invalid_request_errors. Link: https://lore.kernel.org/r/20191107224855.417647-1-colin.king@canonical.com Signed-off-by: Colin Ian King Reviewed-by: Jason Gunthorpe Signed-off-by: Jason Gunthorpe

RDMA/ocrdma: Make ocrdma_pma_counters() return void

2019-11-06T19:38:57Z

This function always returns 0, so just use void and remove the bogus checking at the only call site. Link: https://lore.kernel.org/r/20191029062745.7932-6-leon@kernel.org Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/mad: Allocate zeroed MAD buffer

2019-11-06T19:38:28Z

Ensure that MAD output buffer is zero-based allocated in all the callers of process_mad and remove the various memset()'s from the drivers. Link: https://lore.kernel.org/r/20191029062745.7932-3-leon@kernel.org Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

Merge branch 'devx-async' into k.o/for-next

2019-01-29T20:49:31Z

Yishai Hadas says: Enable DEVX asynchronous query commands This series enables querying a DEVX object in an asynchronous mode. The userspace application won't block when calling the firmware and it will be able to get the response back once that it will be ready. To enable the above functionality: - DEVX asynchronous command completion FD object was introduced. - The applicable file operations were implemented to enable using it by the user application. - Query asynchronous method was added to the DEVX object, it will call the firmware asynchronously and manages the response on the given input FD. - Hot unplug support was added for the FD to work properly upon unbind/disassociate. - mlx5 core fence for asynchronous commands was implemented and used to prevent racing upon unbind/disassociate. This branch is based on mlx5-next & v5.0-rc2 due to dependencies, from git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux * branch 'devx-async': IB/mlx5: Implement DEVX hot unplug for async command FD IB/mlx5: Implement the file ops of DEVX async command FD IB/mlx5: Introduce async DEVX obj query API IB/mlx5: Introduce MLX5_IB_OBJECT_DEVX_ASYNC_CMD_FD Signed-off-by: Jason Gunthorpe

infiniband: ocrdma: no need to check return value of debugfs_create functions

2019-01-24T16:22:30Z

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Signed-off-by: Greg Kroah-Hartman Signed-off-by: Jason Gunthorpe

cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37Z

We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out. This change was generated with the following Coccinelle SmPL patch: @ replace_dma_zalloc_coherent @ expression dev, size, data, handle, flags; @@ -dma_zalloc_coherent(dev, size, handle, flags) +dma_alloc_coherent(dev, size, handle, flags) Suggested-by: Christoph Hellwig Signed-off-by: Luis Chamberlain [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig

RDMA/ocrdma: Use PCI-ID as an identification in debugfs

2018-12-11T21:38:17Z

In opposite to current implementation of identification based on device name, PCI-ID identification provides stable names suitable for device rename. Change ocrdma debugfs representation to use PCI-ID. Signed-off-by: Leon Romanovsky Reviewed-by: Yuval Shaia Acked-by: Selvin Xavier Signed-off-by: Jason Gunthorpe

RDMA/drivers: Use dev_name instead of ibdev->name

These return the same thing but dev_name is a more conventional use of the kernel API. Signed-off-by: Jason Gunthorpe Reviewed-by: Leon Romanovsky
