Subject: [PATCH V2 0/9] Add Mellanox mlx5 driver for Connect-IB devices
Hi Roland, all
Here's V2 of the driver, with Dave's and Roland's comments addressed,
looking forward to see if we have OK from Roland to merge that into 3.11
Jack, Moshe and Or.
changes from V1:
- Addreessed Dave Miller's comments:
* Local variables in functions listed from longest to shortest
* --i/++i changed to i--/i++ in all for-loops
* Removed leading /* empty line from all comments
* magic constants given names
* endianness code moved to driver.h, and defined an endianness-dependent macro
for use in assignment.
* destroy_msg_cache() duplicated code removed
- Addressed Roland's comments:
* Renamed foo_spl to foo_lock for spinlocks.
* Eliminated magic number from mlx5_cmd_stats field declaration in struct mlx5_cmd.
* Eliminated unused procedure mlx5_ib_umem_populate_pas()
command execution times, but all file-name-based mask bits removed.
* Cleaned up mlx5_ib.h:
* Added new patch for ib_verbs.h, adding reserved values to several enums
* For several ib-core enums, added reserved values for use by low-level drivers.
By defining macros at the low level (i.e., renaming the reserved values, in effect), the
ll drivers may use these enums without needing to duplicate the ib-core enums while adding
extra values. This fixes compilation problems such as:
/home/roland/Src/linux-merge.git/drivers/infiniband/hw/mlx5/qp.c:975:2:
error: case value 4671 not in enumerated type enum ib_qp_type
* Changed ib_latency_class to mlx5_ib_latency_class, visible only in low-level driver
* Eliminated the unused IB_WR_xxx_PSV enums
* Defined macros MLX5_IB_SEND_UMR_UNREG, MLX5_IB_QPT_REG_UMR, and MLX5_IB_WR_UMR,
taking advantage of the reserved values added to the ib_core enums.
* debug-mask removed from mlx5_ib
* Regarding mlx5_core, still have a debug mask to enable printouts of command data and
* Removed forced -Wall -Werror -DDEBUG settings in the mlx5 core/ib makefiles
changes from V0:
- Per Dave's request, cross posting to both netdev and linux-rdma, to see
if there are comments from netdev on the core driver.
From: Eli Cohen <eli@...lanox.com>
The patches that follow constitute the driver for Mellanox's 5th generation
of HCAs named Connect-IB.
The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This
partitioning resembles what we have for mlx4 with the substantial difference
that mlx5_ib is the pci device driver and not mlx5_core.
mlx5_core provides general functionality that is intended to be used by
other Mellanox devices that will be introduced in the future. In this sense,
it can be perceived as a library. mlx5_ib has a similar role as any hardware
device under drivers/infiniband/hw.
The patches are partitioned to avoid exceeding the 100KB vger.kernel.org
limitation. They are divided such that the first three ones have the code
of the mlx5_core driver, and the last five the code of the mlx5_ib driver.
Only the last patch per driver adds the Makefiles and Kconfigs, to make
things robust for future bisections.
PPC is not yet supported but support will be included in the near future.
