Subject: [PATCH v2 0/5] ntb perf, ntb tool and ntb-hw improvements
Date: Tue, 10 Mar 2020 15:54:49 -0500	[thread overview]
Message-ID: <1583873694-19151-1-git-send-email-sanju.mehta@amd.com> (raw)

This patch series modifies the ntb perf code to
have separate functions for CPU and DMA transfers.
It also adds handling for -EAGAIN error code so
that we re-try sending commands later.

Fixes have been made to ntb_perf, ntb_tool and 
ntb_hw* files.

The patches are based on Linus' tree,

git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

v2: Incorporated improvements suggested by Logan Gunthorpe

Arindam Nath (2):
  ntb_perf: refactor code for CPU and DMA transfers
  ntb_perf: send command in response to EAGAIN

Logan Gunthorpe (1):
  ntb: hw: remove the code that sets the DMA mask

Sanjay R Mehta (2):
  ntb_perf: pass correct struct device to dma_alloc_coherent
  ntb_tool: pass correct struct device to dma_alloc_coherent
