Building a computer to run sculpt
by Pirmin Duss 28 Apr '22

28 Apr '22

Hello Genodians I would like to build a computer to run sculpt on. I have some parts that at the moment only collect dust. I would like to build a computer to run sculpt on from these and some that I will buy new (CPU / Mainboard). From the unofficial Genode HCL (http://usr.sysret.de/jws/genode/hcl.html) I would guess a 10th generation Intel with integrated graphics would be a good a save starting ground. As the mainboard I would use a ASUS MB PRO Q570M-C which is 11th generation ready. The reason for this MB is that the Q570 chipset supports AMT which would allow me to debug problems via Ethernet. Do you think that a system built with these components would run sculpt well or are there some pitfalls that I have overlooked? Best regards, Pirmin

Design Question about implementing RPC on top of IPC
by Sid Agrawal 25 Apr '22

25 Apr '22

Hi Genode, I am building userspace on seL4 directly and have run into a design issue. I am implementing server and client using badged endpoints. I think Genode would have run into the same issue, and I would like to understand better how Genode solves it. It is not directly a Genode question, but I would benefit from your experience. Below I have laid out the scenario, the issue, and some questions. *Scenario* I have a userspace server that implements the functionality for an object(say type obj_T1). The server hands out badged-endpoints to clients to interact with this object. The badge is the virtual address of the object's struct in the server’s virtual address space. A client can interact with the object by sending messages on this badged endpoint. The client never learns the badge value. The kernel extracts the badged value when the server receives a message on this endpoint. By using the badge value, the server knows which object the client is trying to manipulate. The same PD, which implements the 1st server, also implements another server(in a separate thread, but same address space) for another object type (say type obj_T2). The server follows the same paradigm of handing out badged endpoints and using the badges values to keep track of the object. *Issue* I have a scenario where the client wants to invoke the functionality of obj_T1. This functionality needs access to obj_T2 as well. The client has badged EP caps to both objects. The client can invoke the badged EP handed out by server-1 for obj_T1 and give the badged EP of obj_T2 as an extraCap in the IPC message(or vice versa). Since the server has no way to look up the badge of the second cap, it cannot look up the underlying object for obj_T2. So my questions are: 1. Is there a way for a PD to look up the badge value of badged EP? I think the answer is no, but I thought I would still ask. 2. Is my idea of using the badge to keep track of the underlying object on the right track? Is there a better way of going about doing it? 3. As a potential solution, I can extend my server to add a new function, say GETID, which returns the badge value of a given object(i.e., EP). Since I know that the server always badges the EP with the virtual address of the struct, it is a trivial call to implement. But I somehow feel like this is not a neat idea, not quite sure why. Thanks for the help, everyone! Thanks, Sid Graduate Student @ UBC sid-agrawal.ca

Sculpt OS 22.04 Release Candidate (RC)
by Christian Helmuth 20 Apr '22

20 Apr '22

Hello community, today we published a Release Candidate of the Sculpt operating system for x86-PC. During the last months we worked hard to apply our reimagined Linux-device-driver environment also to PC devices and updated drivers for USB, Wifi, and Intel graphics to a recent Linux kernel version. This opens the prospect to support new PC platforms (speak recent notebook devices) more easily in future releases. The upcoming version of Sculpt replaces multiple integral device drivers at once. For this reason, we concluded to pre-release an RC and invite all Sculpt users to test it in their current setups. Please feel to report back any regression, flaw, or oddity on this list or the issue tracker over the next couple of days, so we can address them before the final release. The release candidate is based on the current master branch https://github.com/genodelabs/genode/commit/8ece2366354c941ad2206f3d511cd75… and can be downloaded as ready-to-use disk image from https://genode.org/files/sculpt/sculpt-22-04rc.img https://genode.org/files/sculpt/sculpt-22-04rc.img.asc (GPG signature) Happy testing Christian -- Christian Helmuth Genode Labs https://www.genode-labs.com/ · https://genode.org/ https://twitter.com/GenodeLabs · https://genodians.org/ Genode Labs GmbH · Amtsgericht Dresden · HRB 28424 · Sitz Dresden Geschäftsführer: Dr.-Ing.

Announcement: Genode OS Framework version 22.02 released
by Norman Feske 28 Feb '22

28 Feb '22

We just released Genode version 22.02 today. https://genode.org/news/genode-os-framework-release-22.02 One highlight of this version is the transformation of Sculpt OS into a framework for custom system images, thereby making Sculpt's flexible architecture easily available for the creation of special-purpose OS appliances. A first example of such an appliance is the bare-bones Sculpt OS version for the Pinephone that I demonstrated at my recent FOSDEM talk. Another example is the ability to run Sculpt OS atop Linux for rapid development and debugging. Another major feature is the new ability to use 3D acceleration for guest OSes running in VirtualBox 6. This became possible thanks to various optimizations and robustness improvements of the underlying Intel GPU stack. A third prominent topic is the continued work on device drivers. This time, we started to apply our new DDE-Linux approach to PC drivers, taking a fresh port of a USB host-controller driver as the first example. Another noteworthy driver-related development is the gained ability to access the modem on the Pinephone. Quick summary of the topics: - Framework for special-purpose Sculpt-based operating systems - First version Sculpt OS on the Pinephone - Sculpt OS running on the Linux kernel - Modularized source-code organization - Base framework and OS-level infrastructure - Tightened API and default warning levels - VFS plugin for packet-level network access - Black-hole server component - Device drivers - New Linux-device-driver environment for PC drivers - GPU-driver improvements - Pinephone modem access - Audio improvements and 3D acceleration for VirtualBox 6 - Completed C and stdc++ support for the RISC-V architecture The complete picture is given by the official release documentation: https://genode.org/documentation/release-notes/22.02 Have fun with exploring the new release!

Re: Hyperbola OS package (Arch based) for setting Genode development environment
by Sagar Acharya 22 Feb '22

22 Feb '22

Resolved the issue. I have made a package named genode-dev which you can check at https://notabug.org/sagaracharya/hyperbola_os . Steps to install. 1. Clone repo. 2. Go to directory of genode-dev. 3. makepkgOptional: If a dependency is not installed, go to that dependency's directory and use ../build.sh or makepkg You should be able to install it on systems with doas. It builds the toolchain which takes about 2.5 hours. To install on systems with sudo, edit genode-dev.install and remove SUDO=doas , use sha512sum genode-dev.install and update the sha512sums of PKGBUILD , and then use makepkg.

Hyperbola OS package (Arch based) for setting Genode development environment
by Sagar Acharya 22 Feb '22

22 Feb '22

Hey folks, I'm almost done with a PKGBUILD which would set up a Genode development environment for Arch like OSes. I'm facing the following error: ...installing tool chain to '/usr/local/genode/tool/21.05'... bash: line 1: sudo: command not found make: *** [tool/tool_chain:489: install] Error 127 Tool for preparing Genode build directories ... Hyperbola uses OpenBSD's doas. I guess Genode uses sudo. Can someone please patch this for doas too? Once it's completed, it can be used by users of Archlinux, Hyperbola, Parabola OSes. Thanking you Sagar Acharya
