Subject: [PATCH 0/4] ntb perf and ntb tool improvements
Date: Wed,  5 Feb 2020 22:46:54 +0530	[thread overview]
Message-ID: <cover.1580921119.git.arindam.nath@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 and ntb_tool
to use 'struct device' associated with 'struct
pci_dev' rather than 'struct ntb_dev'.

The patches are based on Linus' tree,

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

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

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