mlx5: Use enum to indicate adapter page size

2013-11-08T22:43:01Z

The Connect-IB adapter has an inherent page size which equals 4K. Define an new enum that equals the page shift and use it instead of using the value 12 throughout the code. Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

mlx5: Clear reserved area in set_hca_cap()

2013-11-08T22:43:00Z

Firmware spec requires reserved fields to be cleared when calling set_hca_cap. Current code queries and copy to the set area, possibly resulting in reserved bits not cleared. This patch copies only writable fields to the set area. Fix also typo - msx => max Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

mlx5: Support communicating arbitrary host page size to firmware

2013-11-08T22:43:00Z

Connect-IB firmware requires 4K pages to be communicated with the driver. This patch breaks larger pages to 4K units to enable support for architectures utilizing larger page size, such as PowerPC. This patch also fixes several places that referred to PAGE_SHIFT instead of explicit 12 which is the inherent page shift on Connect-IB. Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

IB/mlx5: Multithreaded create MR

2013-11-08T22:42:59Z

Use asynchronous commands to execute up to eight concurrent create MR commands. This is to fill memory caches faster so we keep consuming from there. Also, increase timeout for shrinking caches to five minutes. Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

IB/mlx5: Fix eq names to display nicely in /proc/interrupts

2013-10-10T16:23:59Z

It's helpful for a driver to put the pci slot name in its interrupt names, so /proc/interrupts will show the pci slot of the device. Signed-off-by: Sagi Grimberg Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

mlx5: Fix layout of struct mlx5_init_seg

2013-10-10T16:23:57Z

The layout of struct health_buffer was not according to firmware specification. Fix it to comply. Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

mlx5: Remove checksum on command interface commands

2013-10-10T16:23:56Z

Checksum calculations consume CPU resources and can be significant to the rate of resource creation/destruction. Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changes

2013-08-15T22:42:57Z

In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

mlx5: remove health handler plugin

2013-08-05T18:04:12Z

Remove this code, per Dave Miller's request, since it is not being used anywhere in the kernel. Signed-off-by: Eli Cohen Signed-off-by: David S. Miller

mlx5_core: Implement new initialization sequence

2013-07-31T21:12:24Z

Introduce enbale_hca and disable_hca commands to signify when the driver starts or ceases to operate on the device. In addition the driver will use boot and init pages count; boot pages is required to allow firmware to complete boot commands and the other to complete init hca. Command interface revision is bumped to 4 to enforce using supported firmware. This patch breaks compatibility with old versions of firmware (< 4); however, the first GA firmware we will publish will support version 4 so this should not be a problem.
