What do you think? I'm not a kernel mainline developer so I don't understand the real meaning. Below there is my new proposal, but before accepting it please hear this new idea, that could be better and possible to be used also in 2.6.33 kernel: "Adding to Maemo or Debian or Gentoo embedded systems a debugging environment similar to Android: I mean the possibility to connect to a single debugging "server" and, in a graphical very easy (Eclipse or QT Creator) way, connecting the gdb to the desired process, or, see rootfs, or tracing cpu usage, ..." What I really like of Android is the fantastique environment, with the emulator that can do step by step debugging.... --------------------------------------------------------- Summary: Feasibility analisys of Android introduction in a completely tested industrial device. Description: Android is a new important graphic interface and a java virtual machine optimized for embedded devices. The Android breaking feature in respect of traditional GNU Linux embedded operating systems has discouraged the possibility to enhance an already existing GNU Linux embedded industrial device with at least the Android's graphic interface. By now Android has been fully ported to Cortex A8 cpus starting new mobile phone projects from scratch. The reasons to do this work are commercial because of Google market power, but are also technical, because Android debugging environment is very nice for not embedded developers. This could help the diffusion of opensource embedded GNU Linux in a wider point of view. The work should be maybe against the 2.6.31 kernel. The idea is to preserve industrial tested development but adding Android graphical interface and debugging features. The cpu dependency of the porting will be as small as possible. The most important kernel interfaces will be investigated, at least framebuffer for tft lcd, touchscreen, audio ac97 interface, usb host for usb pen. Related work: * Android Porting - http://www.kandroid.org/<wbr></wbr>android_pdk/ * Android Pxa270 - http://android-pxa270.sourceforge.net/ Scope: This should take more than 1 month for feasibility analysis. ------------------------------------------------------ -- www.opensurf.it -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
