Subject: [PATCH 0/2] add platform bus
Date: Wed, 25 Jan 2023 11:38:07 +0100 [thread overview]
Message-ID: <20230125103809.1250080-1-tduszynski@marvell.com> (raw)
Platform bus is a bus under Linux which manages devices that do not have
any discovery-mechanism built in. Linux learns about platform devices
directly from device-tree during boot-up phase.
Afterwards if userspace wants to use some particular device driver being
usually a mixture of vdev/rawdev gets developed.
In order to simplify that introduce a DPDK platform bus which provides
auto-probe experience and separates a bus logic from the driver itself.
Now only devices which are backed-by vfio-platform kernel driver
are supported, though other options may be added if necessary.
Tomasz Duszynski (2):
lib: add helper to read strings from sysfs files
bus: add platform bus
