Subject: [PATCH 0/3] Add support for AMD AE4DMA controller driver
Date: Mon, 11 Sep 2023 14:25:21 -0500 [thread overview]
Message-ID: <1694460324-60346-1-git-send-email-Sanju.Mehta@amd.com> (raw)
From: Sanjay R Mehta <sanju.mehta@amd.com>
This patch series add support for AMD AE4DMA controller which
performs high bandwidth memory-to-memory and IO copy operation,
performs DMA transfer through queue based descriptor management.
The AE4DMA controller allows for configuration of the number of
queues per controller, with a range from 1 to 16. This configuration
can be conveniently adjusted using the driver's "max_hw_q" parameter.
The AMD Processor features multiple ae4dma device instances,
with each controller supporting a maximum of 16 DMA queues.
