Subject: [PATCH v7 26/29] fpga: dfl: afu: add DFL_FPGA_GET_API_VERSION/CHECK_EXTENSION ioctls support
Date: Sat, 30 Jun 2018 08:53:33 +0800	[thread overview]
Message-ID: <1530320016-24712-27-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1530320016-24712-1-git-send-email-hao.wu@intel.com>

DFL_FPGA_GET_API_VERSION and DFL_FPGA_CHECK_EXTENSION ioctls are common
ones which need to be supported by all feature devices drivers including
FME and AFU. This patch implements above 2 ioctls in FPGA Accelerated
Function Unit (AFU) driver.
