Subject: [PATCH v7 01/13] bcm-vk: add bcm_vk UAPI
Date: Tue, 17 Nov 2020 15:23:08 -0800 [thread overview]
Message-ID: <20201117232320.4958-2-scott.branden@broadcom.com> (raw)
In-Reply-To: <20201117232320.4958-1-scott.branden@broadcom.com>
Add user space api for bcm-vk driver.
Provide ioctl api to load images and issue reset command to card.
FW status registers in PCI BAR space also defined as part
of API so that user space is able to interpret these memory locations
as needed via direct PCIe access.
