Windowed Terminal
I created a windowed terminal run script. It uses the cli_monitor server (used in terminal_mux.run) in a windowed nit_fb, and it works, except I can't switch between terminals like I can in terminul_mux using Ctrl+X. How can I add this functionality? I've attached the run script for you to look at. terminal_window.run Description: Binary data -- ___ genode-main mailing list genode-main@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/genode-main
Ext4
It seems that Genode lacks ext4 support. Is there any intention to port an ext4 driver to Genode? How hard would this task be? -- ___ genode-main mailing list genode-main@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/genode-main
File Manager
What level of file management does Genode have? Is there a graphical file manager available? Does noux support file management? Also, since I am considering implementing a file manager if one doesn't already exist, how would I do it? I'm thinking of porting PCManFM to Genode, so how does the filesystem work? (Does it have a single root directory like Linux, or does it just give you access to each filesystem like in Windows?) -- ___ genode-main mailing list genode-main@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/genode-main
Query: Two OS
Hi everyone, I am Franc, new to Genode, At the starting stage, I am interested in exploring trustzone demo showed in the video : https://www.youtube.com/watch?feature=player_embedded&v=voFV1W4yyY8 So, I have some query related to this, As we can run two OS in both world, Genode in the secure world and other OS in the normal world, so OS running in the normal world should have different configuration from Normal bootable image or not on a particular Board ? if we have to modify the OS image to run in the normal world then what all are the changes we have to do in that ? cheers !!

Re: Full Genode Install
Hello,
btw, would you be comfortable to tell me your name or at least a nick
name? I feel a little bad about starting an email with "Hi Nobody". ;-)

I think what you are looking for is located at 'os/src/app/cli_monitor',
which is a command-line-based application for starting and killing
subsystems. To give it a try, please refer to the run script
'gems/run/termina_mux.run', which combines the CLI monitor with a
terminal multiplexer called 'terminal_mux'. After booting the system,
press control-x to bring up the terminal-mux menu where you can switch
between CLI monitor and a log view. In CLI monitor, press tab to see a
list of commands. When having started a subsystem (e.g., 'start noux' -
note that you can use tab completion), you can switch to the new session
by pressing control-x again.
As a nice exercise, you may try to integrate CLI monitor with the window
manager (see 'gems/run/wm.run') using the graphical terminal
('gems/src/server/terminal') and nit_fb ('os/src/server/nit_fb').

Normally, parent processes (like init, launchpad, CLI monitor) obtain
binaries and shared libraries as so-called ROM modules. The component
fs_rom ('os/src/server/fs_rom') provides a ROM service that hands out
files from a file system as ROM modules. By combining it with a
file-system server (such as rump_fs), you can start subsystems from a
file system.
In general, the best way to go forward is to explore the various run
scripts and components to get a tangible feel of which components are
there and how to combine them in useful ways.
Have fun!

Re: Full Genode Install
Thanks. The Genode documentation does seem somewhat lacking, so could you please help me? What apps are already available for launching Genode programs? I think that finding a good way of launching programs (e.g. through a terminal emulator) would be the first thing that I would need to do. Also, can executables and libraries be loaded from filesystems? That seems like the solution to avoid needing to build new system images. Is there anything else helpful that I should know about Genode to build it as a general-purpose OS?

Re: 回复： Is there any method to obtain real-world date and time in Genode?
Hello, let me add that there is a middle ground between using the RTC driver and the time-stamp counter (TSC), namely the 'Timer::Session::elapsed_ms' function. This function returns the number of milliseconds since timer session was created. By combining it with the RTC driver, the expensive call to the RTC driver could be done at high intervals only. In between, the less expensive 'elapsed_ms' function could be used to obtain time durations at a finer granularity. Still, 'elapsed_ms' does not come for free because it involves an RPC to the timer service. Ideally, a get-time function would be a mix of the different facilities. The RTC to obtain the coarse time of the day and date, the TSC for high accuracy in the order of microseconds and the 'elapsed_ms' function for accuracy in the order of milliseconds. It is true that the TSC frequency may depend on the clock speed, speed stepping, power savings etc. For this reason, the TSC values cannot be used as is but they must be calibrated. E.g., the timer service can be used to determine the ratio of TSC values per second. To account for TSC frequency changes during runtime, the ratio could be updated at certain intervals. As of now, the libc does not provide a convenient function that combines the different facilities for you. But the instruments outlined above should principally enable you to construct a highly accurate get-time function with very little overhead in the TSC-based common case when neither 'Timer::Session::elapsed_ms' nor the RTC is called.

Re: Full Genode Install
Hello, I'm afraid that we are not really there yet. You are right that a lot of puzzle pieces are already in place and Genode can certainly be used to build interesting application scenarios. Within Genode Labs, we are regularly building quite sophisticated scenarios including VirtualBox, Arora, Seoul, Rump-kernel-based file systems, and many more components. But for being fit as a general-purpose OS, there is still the need to address some remaining points, in particular proper packaging. Right now, we use run scripts to build whole system scenarios. For comprehensive scenarios, the build can take hours. This is acceptable for special-purpose systems but it does not scale enough for a general-purpose OS. The work flow of building and using the latter should be far more interactive. E.g., installing new subsystem on the fly without the need to rebuild a system image or even reboot the machine. That said, we definitely strive for Genode to become a general-purpose OS. So we will take on these challenges. This intention is best illustrated by our recently added GUI stack (the composition of window manager, nitpicker, decorator, window layouter). So stay tuned! ;-) Of course, you are very welcome to investigate Genode as a general-purpose OS on your own. E.g., porting the Debian bootstrapping to a Noux instance would certainly be an interesting project. Or another (and in my personal opinion more thrilling) idea, port the Nix package manager to a Noux environment. Cheers Norman -- Dr.-Ing.

Re: tz_vmm on imx6 Board
I just discovered that you could add some verbosity to the platform
initialization of base-hw. Just change at
https://github.com/genodelabs/genode/blob/14.08/repos/base-hw/src/core/platform.cc#L131
from
enum { VERBOSE = 0 };
to
enum { VERBOSE = 1 };

Re: tz_vmm on imx6 Board
Hello Chirag Garg, unfortunately base-hw does not log the discovered "boot modules" which are added to the ROM file system. Nevertheless I expect your config file refers to the ROM binary "linux" while your ROM file system does not contain such a file. Please double-check your config file and the var/run/ directory.
