      IB/mlx5: Remove support for IB_DEVICE_LOCAL_DMA_LKEY · c6790aa9
      由 Sagi Grimberg 提交于 
      Commit 96249d70 ("IB/core: Guarantee that a local_dma_lkey
is available") allows ULPs that make use of the local dma key to keep
working as before by allocating a DMA MR with local permissions and
converted these consumers to use the MR associated with the PD
rather then device->local_dma_lkey.

ConnectIB has some known issues with memory registration
using the local_dma_lkey (SEND, RDMA, RECV seems to work ok).

Thus don't expose support for it (remove device->local_dma_lkey
setting), and take advantage of the above commit such that no regression
is introduced to working systems.

The local_dma_lkey support will be restored in CX4 depending on FW
capability query.

      IB/mlx5: Collect signature error completion · d5436ba0
      由 Sagi Grimberg 提交于 
      This commit takes care of the generated signature error CQE generated
by the HW (if happened).  The underlying mlx5 driver will handle
signature error completions and will mark the relevant memory region
as dirty.

Once the consumer gets the completion for the transaction, it must
check for signature errors on signature memory region using a new
lightweight verb ib_check_mr_status().

In case the user doesn't check for signature error (i.e. doesn't call
ib_check_mr_status() with status check IB_MR_CHECK_SIG_STATUS), the
memory region cannot be used for another signature operation
(REG_SIG_MR work request will fail).

      mlx5: Implement create_mr and destroy_mr · 3121e3c4
      由 Sagi Grimberg 提交于 
      Support create_mr and destroy_mr verbs.  Creating ib_mr may be done
for either ib_mr that will register regular page lists like
alloc_fast_reg_mr routine, or indirect ib_mrs that can register other
(pre-registered) ib_mrs in an indirect manner.

In addition user may request signature enable, that will mean that the
created ib_mr may be attached with signature attributes (BSF, PSVs).

Currently we only allow direct/indirect registration modes.

      IB/mlx5: Fix micro UAR allocator · c1be5232
      由 Eli Cohen 提交于 
      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.

      net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changes · 0a324f31
      由 Moshe Lazer 提交于 
      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_core: Implement new initialization sequence · cd23b14b
      由 Eli Cohen 提交于 
      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.
