Subject: [PATCH 09/16] fpga: intel: fme: add header sub feature support
Date: Thu, 30 Mar 2017 20:08:09 +0800 [thread overview]
Message-ID: <1490875696-15145-10-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1490875696-15145-1-git-send-email-hao.wu@intel.com>
From: Kang Luwei <luwei.kang@intel.com>
The header register set is always present for FPGA Management Engine (FME),
this patch implements init and uinit function for header sub feature and
introduce several read-only sysfs interfaces for the capability and status.
Sysfs interfaces:
* /sys/class/fpga/<fpga.x>/<intel-fpga-fme.x>/ports_num
Read-only. Number of ports implemented
* /sys/class/fpga/<fpga.x>/<intel-fpga-fme.x>/bitstream_id
Read-only. Blue Bitstream identifier number
* /sys/class/fpga/<fpga.x>/<intel-fpga-fme.x>/bitstream_metadata
Read-only. Blue Bitstream meta data
