IB/mlx5: Implement modify CQ

2014-01-23T07:23:49+00:00

Modify CQ is used by ULPs like IPoIB to change moderation parameters.  This
patch adds support in mlx5.

IB/mlx5: Fix micro UAR allocator

2014-01-14T21:54:23+00:00

The micro UAR (uuar) allocator had a bug which resulted from the fact
that in each UAR we only have two micro UARs avaialable, those at
index 0 and 1.  This patch defines iterators to aid in traversing the
list of available micro UARs when allocating a uuar.

In addition, change the logic in create_user_qp() so that if high
class allocation fails (high class means lower latency), we revert to
medium class and not to the low class.

mlx5: Use enum to indicate adapter page size

2013-11-08T22:43:01+00:00

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.

mlx5: Clear reserved area in set_hca_cap()

2013-11-08T22:43:00+00:00

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

mlx5: Support communicating arbitrary host page size to firmware

2013-11-08T22:43:00+00:00

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.

IB/mlx5: Multithreaded create MR

2013-11-08T22:42:59+00:00

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.
