IB/uverbs: Move QP, SRQ, WQ type and flags to UAPI

2020-05-21T23:39:35+00:00

These constants are going to be used in the ioctl interface in coming
patches so they are part of the UAPI, place them in the correct header
for clarity.

RDMA/core: Add the core support field to METHOD_GET_CONTEXT

2020-01-16T19:55:46+00:00

Add the core support field to METHOD_GET_CONTEXT, this field should
represent capabilities that are not device-specific.

Return support for optional access flags for memory regions. User-space
will use this capability to mask the optional access flags for
unsupporting kernels.

RDMA/uverbs: Add new relaxed ordering memory region access flag

2020-01-16T19:55:46+00:00

Add a new relaxed ordering access flag for memory regions.  Using memory
regions with relaxed ordeing set can enhance performance.

This access flag is handled in a best-effort manner, drivers should ignore
if they don't support setting relaxed ordering.

RDMA/core: Add optional access flags range

2020-01-16T19:55:46+00:00

Define a range of access flags that are defined to be optional, both
uverbs and drivers should enable getting them and use if they are
applicable

This will be used, for example, for the relaxed ordering access flag which
unsupporting drivers can ignore.

RDMA/uapi: Fix and re-organize the usage of rdma_driver_id

2019-10-17T19:41:06+00:00

Fix 'enum rdma_driver_id' to preserve other driver values before that
RDMA_DRIVER_CXGB3 was deleted. As this value is UAPI we can't affect
other values as of a deletion of one driver id.

IB/core: Move query port to ioctl

2018-12-20T22:18:24+00:00

Add a method for query port under the uverbs global methods.  Current
ib_port_attr struct is passed as a single attribute and port_cap_flags2 is
added as a new attribute to the function.

IB/uverbs: Add support to advise_mr

2018-12-18T22:19:46+00:00

Add new ioctl method for the MR object - ADVISE_MR.

This command can be used by users to give an advice or directions to the
kernel about an address range that belongs to memory regions.

A new ib_device callback, advise_mr(), is introduced here to suupport the
new command. This command takes the following arguments:

- pd:		The protection domain to which all memory regions belong
- advice: 	The type of the advice
	  	* IB_UVERBS_ADVISE_MR_ADVICE_PREFETCH - Pre-fetch a range of
		an on-demand paging MR
	  	* IB_UVERBS_ADVISE_MR_ADVICE_PREFETCH_WRITE - Pre-fetch a range
		of an on-demand paging MR with write intention
- flags:	The properties of the advice
		* IB_UVERBS_ADVISE_MR_FLAG_FLUSH - Operation must end before
		return to the caller
- sg_list:	The list of memory ranges
- num_sge:	The number of memory ranges in the list
- attrs:	More attributes to be parsed by the provider
