Hi Norman Quoting Norman Feske <norman.fe...@genode-labs.com>:
I did a bit of planing on the over the last weekend. Attached you find the document I wrote with all the informations How I think the drivers should could interact with each other. One question I have, is should the IoConfig service be integrated in to the platform driver or a separate driver.
Hi Pirmin,Are there some examples, where I can look how such a hardware abstraction server should be structurized?a good candidate is the existing GPIO driver for the i.MX53 platform located at repos/os/src/drivers/gpio/imx53. It shows well how to keep the three main concerns of a device-driver component well separated: * The device specification (i.e., the register layout) resided in the header gpio.h, expressed in C++ types, * The driver logic is implemented in driver.h, * The glue with the Genode world is implemented main.cc The driver uses the MMIO framework, which is described in Section 8.15 of the manual.
I will use this information, as soon I find the time to start the implementation.
Happy hacking! I'm off to the Hack'n'Hike for now :-)
I hope you had good weather conditions. Pirmin
