IB/rdmavt: Correct qp_priv_alloc() return value test

2016-06-23T14:16:15Z

The current drivers return errors from this calldown wrapped in an ERR_PTR(). The rdmavt code incorrectly tests for NULL. The code is fixed to use IS_ERR() and change ret according to the driver return value.

IB/core: Fix bit curruption in ib_device_cap_flags structure

2016-06-07T13:50:54Z

ib_device_cap_flags 64-bit expansion caused caps overlapping and made consumers read wrong device capabilities. For example IB_DEVICE_SG_GAPS_REG was falsely read by the iser driver causing it to use a non-existing capability. This happened because signed int becomes sign extended when converted it to u64. Fix this by casting IB_DEVICE_ON_DEMAND_PAGING enumeration to ULL.

IB/core: Make device counter infrastructure dynamic

2016-05-26T16:52:51Z

In practice, each RDMA device has a unique set of counters that the hardware implements. Having a central set of counters that they must all adhere to is limiting and causes many useful counters to not be available. Therefore we create a dynamic counter registration infrastructure. The driver must implement a stats structure allocation routine, in which the driver must place the directory name it wants, a list of names for all of the counters, an array of u64 counters themselves, plus a few generic configuration options. We then implement a core routine to create a sysfs file for each of the named stats elements, and a core routine to retrieve the stats when any of the sysfs attribute files are read. To avoid excessive beating on the stats generation routine in the drivers, the core code also caches the stats for a short period of time so that someone attempting to read all of the stats in a given device's directory will not result in a stats generation call per file read. Future work will attempt to standardize just the shared stats elements, and possibly add a method to get the stats via netlink in addition to sysfs.

IB/rdamvt: Fix rdmavt s_ack_queue sizing

2016-05-26T16:21:10Z

rdmavt allows the driver to specify the size of the ack queue, but only uses it for the modify QP limit testing for setting the atomic limit value. The driver dependent size is now used to size the s_ack_queue ring dynamicially. Since the driver knows its size, the driver will use its define for any ring size dependent code.

IB/rdmavt: Max atomic value should be a u8

2016-05-26T16:21:10Z

This matches the ib_qp_attr size and avoids a extremely large value when the lower level driver registers. As part of the patch, the u8 ordinals are moved to the end of the struct to reduce pahole noted excesses.
