Announcement: Genode OS Framework version 15.02 released
by Christian Helmuth 27 Feb '15

27 Feb '15

According to our road map, the overall theme of 2015 is the consolidation and cultivation of the existing feature set rather than the conquering of new grounds. Along these lines, the current release brings with virtualization support on ARM one prominent feature but plenty of changes regarding testing, stability, and performance improvements. The highlights are - Virtualization on ARM - Modular tool kit for automated testing - Improved performance of VirtualBox on NOVA - Libraries and protocol stacks - Update of rump-kernel based file systems - Ports of sqlite and libbz2 - Device drivers - Support for USB touchscreen devices - New wireless configuration interface - New USB session interface - Platforms - Added support for the USB Armory board - IPC helping on the base-hw kernel - Out-of-order page-fault handling on NOVA Following our tradition, the extensive release documentation is available from http://genode.org/documentation/release-notes/15.02 and covers all additions and changes in detail.

Framebuffer
by chirag garg 12 Feb '15

12 Feb '15

Hi all, I was trying to understand the flow of framebuffer flow for given imx53 code in the following directory repos/os/src/drivers/framebuffer/imx53/main.cc In the main function, one static variable "session_component" has been created which uses the "config_attribute" function defined in line number 115 which expect a config file in build process. What is the need of this config file with respect to framebuffer and where should i found this config file in the repository because when i run the framebuffer script it is not able to open config file? Regards Chirag Garg IIT Madras , Rise Lab
