Pine fun - Touchscreen
On our mission to enable the PinePhone hardware for Genode piece by piece, let's turn our attention to the touchscreen device, which is the gateway to interactive system scenarios. Continue...

Pine fun - Display
Having switched the development workflow from the Pine-A64-LTS board to the real deal - the PinePhone - in the previous article, it is time to turn our attention to the arguably most challenging parts of the hardware, namely the display subsystem. Continue...

Linux device driver ports - Choose compilation units
In my first blog post of this series, I've described the motivation to break new grounds in porting Linux drivers to Genode. Moreover, you've seen how to re-use the headers and configuration of a pre-built Linux kernel. In the last blog post, we continued our journey with a new helper tool to generate missing Linux kernel function definitions automatically. This time I'll continue with how to choose the absolutely necessary compilation units for a given driver resp. subsystem. Continue...

Pine fun - One Platform driver to rule them all
In the previous article we exercised direct-device access from user-level components. In Genode systems beyond such toy scenarios, however, it would be irresponsible to follow the path of allowing arbitrary drivers to access any device willy-nilly. Our call for discipline and rigidity is answered by the (rising drum roll) platform driver. Continue...

Linux device driver ports - Generate dummy function definitions
In my last blog post I've described the motivation to break new grounds in porting Linux drivers to Genode. Moreover, you've seen how to re-use the headers and configuration of a pre-built Linux kernel. This time we'll continue by invoking the very first initialization routines. Therefore, a new little helper tool gets introduced to generate missing Linux kernel function definitions automatically. Continue...

Linux device driver ports - Breaking new ground
In my following blog post(s) I want to elaborate on recent attemtps to renew and enhance the way Linux device drivers are ported to Genode. This is highly experimental work. So be warned if you try to follow the same approach: it hasn't proved its worth yet. But first let me explain why to break new grounds at all. Continue...

Pine fun - Device access from the user level
Genode's peripheral device drivers live outside the kernel and have the form of regular user-level components. This article presents how the device-hardware access works under these conditions, while taking the general-purpose I/O pins of the Pine-A64-LTS single-board computer as playground. Continue...
