Subject: [PATCH v2 00/17] NTB: Add NTB hardware abstraction layer
Date: Thu, 21 May 2015 04:20:44 -0400 [thread overview]
Message-ID: <cover.1432192681.git.Allen.Hubbe@emc.com> (raw)
The NTB drivers currently support only one hardware driver, and one
client type. This patch set adds an abstraction layer, enabling
hardware drivers by other vendors, and clients other than ntb_transport.
The commits in this set may also be pulled from:
github.com/allenbh/linux
tagged ntb-abh-v2
The differences can be seen by comparing against the tag ntb-abh-v1.
Different in v2:
- Rewrite shortlog descriptions for spelling and style
- Remove extraneous NTB dependency from Kconfig files
- Reindent Kconfig files with leading tabs
- Reindent some lines in ntb_transport
- Append patch NTB: Rename intel hw to proper platform names
Allen Hubbe (12):
NTB: Move files in preparation for NTB abstraction
NTB: Add NTB hardware abstraction layer
NTB: Add parameters for Intel SNB B2B addresses
NTB: Add ping pong test client
NTB: Add tool test client
NTB: Rate limit ntb_qp_link_work
NTB: Differentiate transport link down messages
NTB: Do not advance transport RX on link down
NTB: Reset transport QP link stats on down
NTB: Use NUMA memory and DMA chan in transport
NTB: Use NUMA memory in Intel driver
NTB: Fix small code format issues in transport
Dave Jiang (5):
NTB: Enable link for Intel root port mode in probe
NTB: Check the device ID to set errata flags
NTB: Improve performance with write combining
NTB: Default to CPU memcpy for performance
NTB: Rename intel hw to proper platform names
