Re: Roadmap 2018

Personally, I'm quite excited that Sculpt enables me to work on Genode each day. This is pretty much different from what I felt one year ago with a rather static scenario that I used only once for a talk. Looking at 2017 in hindsight, I did not invest much time into my personal plan, which was a Genode-native multi-component email workflow including IMAP, SMTP, local (maildir) storage, and mutt as MUA. Nevertheless, I'll extend the plan to 2018 as Sculpt promises less obstacles and features true dynamic Genode subsystems beside the traditional Linux VM. The first natural step is the use of multiple VMs tailored for dedicated purposes of daily work (speak development, email, web browsing). This is not my personal ambition but the first pieces were already put in place by others in the team. This scenario helps to understand and solve the task of sharing data when splitting the daily work into more fine-grained domains. Next, the email VM can be replaced by the Genode email subsystem developed in parallel. Chris, please keep us informed about your progress on the IMAP server scenario if you can. I am also gradually making my systems more modular using VMs (although not quite as granular as what you describe above), and I am currently running an little IMAP server in a *nix VM, which I would love to replace with a Genode "appliance" VM. Everyone, since I'm already chiming in, I might as well throw in this idea as food for thought: It might be possible to piggyback on the work of the "postmarketOS" project ( https://postmarketos.org/ ) to get Genode running on a variety of smartphones with only one porting effort. In a nutshell, they are isolating all the device-specific code into one file, in order to allow creating a single (highly customizable, Alpine Linux-based) OS image to run on all the supported devices. I wonder if it's possible to create a Genode-on-Linux (ARM) scenario on this foundation. In any case, thanks for the amazing work, and Happy New Year to everyone! -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ genode-main mailing list genode-main@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/genode-main
Constrained file descriptors
Hi Norman, before Christmas we chatted about enabling the MMIO session on Linux. You said that you know a possibility to create constrained file descriptors (in such a way that accesses through this descriptor can only access a part of the file). I've done a second search but I couldn't find any useful information regarding this topic. Do you have any further, more specific, information about how to achieve this goal?

You can use the "wandquad" board as a template to add the sabrelite board. It uses an i.MX6 SoC too. You might also have a look at the imx6_sabre branch in my genode repository on github. Just the last commit is interesting, and might apply to the current general master branch. I have once tested the basic log scenario, but I'm not sure by 100% wether it was the sabrelite or the sabre tablet.

Should I use "Terminal" sessions for > send-and-forget IPC, or is there a better option? it depends on the type of content you wish to send. If your content is a *stream* of data, the 'Terminal' session is appropriate. If your content can be expressed as a *state*, better use the 'Report' session interface. In general, you should try to use the report-session interface whenever possible because it does not require the queuing of information. In contrast to streamed data, only the most recently reported state needs to be preserved. Cheers Norman -- Dr.-Ing.

Re: improved fs_rom
Hello Ben, > Also, how well does the vfs server handle config updates? the VFS does not support dynamic reconfiguration.

The order of sub nodes within the top-level node and within nodes defines how content is shadowed. The VFS does not support copy-on-write. A file provided by a read-only file system will stay read only and cannot be changed. However, we plan to supplement copy-on-write support as a plugin later. Until then, the use case of providing an initial version of a config file that can be modified at runtime cannot be covered by the vfs. Here, we still have to use the ram_fs loaded with initial . > Which filesystem/plugin > provides the file? And which one is written to when a new file is > created? A new file is created on the first writeable file system mounted at the directory hosting the new file. You may experiment with the VFS using a file system as a writeable file system and file systems for read-only content. You may also find the various noux scenarios worth looking at because they all use the VFS. In particular, they mount multiple tar archives at '/' where each tar archive contains a '/bin' directory. In the VFS, the joint content of all archives becomes visible. Cheers Norman -- Dr.-Ing.
