e1b95ae0b0 RDMA/mlx5: Return ODP type per MR
Provide an ODP explicit/implicit type as part of 'rdma -dd resource show
mr' dump.

For example:

$ rdma -dd resource show mr
dev mlx5_0 mrn 1 rkey 0xa99a lkey 0xa99a mrlen 50000000
pdn 9 pid 7372 comm ibv_rc_pingpong drv_odp explicit

For non-ODP MRs, we won't print "drv_odp ..." at all.

a2aca4d7f0 Merge branch 'mlx5-rd-sgl' into rdma.git for-next
From Yamin Friedman:

====================
This series from Yamin implements long standing "TODO" existed in rw.c. It
allows the driver to specify a cut-over point where it is faster to build
a lkey MR rather than do a large SGL for RDMA READ operations.

mlx5 HW gets a notable performane boost by switching to MRs.
====================

Based on the mlx5-next branch from
git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for
dependencies

* branch 'mlx5-rd-sgl': (3 commits)
  RDMA/mlx5: Add capability for max sge to get optimized performance
  RDMA/rw: Support threshold for registration vs scattering to local pages
  net/mlx5: Expose optimal performance scatter entries capability

Yamin Friedman
366090564b RDMA/mlx5: Add capability for max sge to get optimized performance
Allows the IB device to provide a value of maximum scatter gather entries
per RDMA READ.

In certain cases it may be preferable for a device to perform UMR memory
registration rather than have many scatter entries in a single RDMA READ.
This provides a significant performance increase in devices capable of
using different memory registration schemes based on the number of scatter
gather entries. This general capability allows each device vendor to fine
tune when it is better to use memory registration.

018c6837f3 RDMA subsystem updates for 5.4
This cycle mainly saw lots of bug fixes and clean up code across the core
 code and several drivers, few new functional changes were made.
 
 - Many cleanup and bug fixes for hns
 
 - Various small bug fixes and cleanups in hfi1, mlx5, usnic, qed,
   bnxt_re, efa
 
 - Share the query_port code between all the iWarp drivers

84da111de0 hmm related patches for 5.4
This is more cleanup and consolidation of the hmm APIs and the very
 strongly related mmu_notifier interfaces. Many places across the tree
 using these interfaces are touched in the process. Beyond that a cleanup
 to the page walker API and a few memremap related changes round out the
 series:
 
 - General improvement of hmm_range_fault() and related APIs, more
   documentation, bug fixes from testing, API simplification &
   consolidation, and unused API removal
 
 - Simplify the hmm related kconfigs to HMM_MIRROR and DEVICE_PRIVATE, and
   make them internal kconfig selects
 
 - Hoist a lot of code related to mmu notifier attachment out of drivers by
   using a refcount get/put attachment idiom and remove the convoluted
   mmu_notifier_unregister_no_release() and related APIs.
 
 - General API improvement for the migrate_vma API and revision of its only
   user in nouveau
 
 - Annotate mmu_notifiers with lockdep and sleeping region debugging
 
 Two series unrelated to HMM or mmu_notifiers came along due to
 dependencies:
 
 - Allow pagemap's memremap_pages family of APIs to work without providing
   a struct device
 
 - Make walk_page_range() and related use a constant structure for function
   pointers

008157528a IB/mlx5: Report and handle ODP support properly
ODP depends on the several device capabilities, among them is the ability
to send UMR WQEs with that modify atomic and entity size of the MR.
Therefore, only if all conditions to send such a UMR WQE are met then
driver can report that ODP is supported. Use this check of conditions
in all places where driver needs to know about ODP support.

Also, implicit ODP support depends on ability of driver to send UMR WQEs
for an indirect mkey. Therefore, verify that all conditions to do so are
met when reporting support.

PI offload (protection information) is a feature that each RDMA provider
can implement differently. Thus, introduce new device attribute to define
the maximal length of the page list for PI fast registration operation. For
example, mlx5 driver uses a single internal MR to map both data and
protection SGL's, so it's equal to max_fast_reg_page_list_len / 2.

mlx5_ib_map_mr_sg_pi() will map the PI and data dma mapped SG lists to the
mlx5 memory region prior to the registration operation. In the new
API, the mlx5 driver will allocate an internal memory region for the
UMR operation to register both PI and data SG lists. The internal MR
will use KLM mode in order to map 2 (possibly non-contiguous/non-align)
SG lists using 1 memory key. In the new API, each ULP will use 1 memory
region for the signature operation (instead of 3 in the old API). This
memory region will have a key that will be exposed to remote server to
perform RDMA operation. The internal memory key that will map the SG lists
will stay private.

Pull rdma updates from Jason Gunthorpe:
 "This has been a smaller cycle than normal. One new driver was
  accepted, which is unusual, and at least one more driver remains in
  review on the list.

  Summary:

   - Driver fixes for hns, hfi1, nes, rxe, i40iw, mlx5, cxgb4,
     vmw_pvrdma

   - Many patches from MatthewW converting radix tree and IDR users to
     use xarray

   - Introduction of tracepoints to the MAD layer

   - Build large SGLs at the start for DMA mapping and get the driver to
     split them

25c13324d0 IB/mlx5: Add steering SW ICM device memory type
This patch adds support for allocating, deallocating and registering a new
device memory type, STEERING_SW_ICM.  This memory can be allocated and
used by a privileged user for direct rule insertion and management of the
device's steering tables.

The type is provided by the user via the dedicated attribute in the
alloc_dm ioctl command.

3b113a1ec3 IB/mlx5: Support device memory type attribute
This patch intoruduces a new mlx5_ib driver attribute to the DM allocation
method - the DM type.

In order to allow addition of new types in downstream patches this patch
also refactors the allocation, deallocation and registration handlers to
consider the requested type and perform the necessary actions according to
it.

Since not all future device memory types will be such that are mapped to
user memory, the mandatory page index output attribute is modified to be
optional.
