Can Genode run on the Mixtile Blade 3?
by Jacek Rużyczka 06 May '23

06 May '23

Good evening Genodians, in a couple of months I'll receive a number of Mixtile Blade 3 SBCs (based on the RK3588) https://www.crowdsupply.com/mixtile-limited/mixtile-blade-3 and would like to (at least) try to equip them with the Genode OS. What's necessary for my project, is clustering four such nodes with a PCIe switch (supplied by Mixtile; see their web page) as well as using single SBCs as storage nodes, which will be connected to a hard drive. Is it possible to port Genode onto this platform, or is this impossible with the current version? I simply don't wanna start an infaust undertaking. Thank you. Regards Jacek Rużyczka

Hello Genodians, those of you, who did not attend this year's FOSDEM physically or virtually, but are interested in my talk about Linux device driver porting to Genode: https://fosdem.org/2023/schedule/event/ddtransplant/ The video recording is now available. Just follow the link above. Regards Stefan -- Stefan Kalkowski Genode labs https://github.com/skalk | https://genode.org

Regarding ARM on Genode
by Divya Sharma 10 Apr '23

10 Apr '23

hello genodians, I'm Trying to port Genode OS for i.MX 8MQ boards (arm_v8a). successfully generated .img file but don't know how to run this img file i don't have i.MX board so I have to run on Ubuntu (linux). I have tried qemu emulator but i think qemu doesn't supported board. (basically want to run genode os for ARM.) Please give some guidance on this. Thanks & Regards

Re: First system image of Sculpt OS for the PinePhone
by Pirmin Duss 13 Mar '23

13 Mar '23

Hello Genodians My first tests of Sculpt OS on the PinePhone. The startup time of the Operating system really impresses me. Not to wait for the phone for a minute or so after powering on is super cool. The GUI is really functional and lets me change settings really quick. It may not be as pretty as the one in slowly booting operating systems, but navigating around is much more logical IMHO. Unfortunately I wasn't able to do any calls. When I turned the power on for the Modem, some steps were counted up (four if I remember correctly), but after that a Message (unknown pin starte) was printed. for some time (maybe 15 Seconds). After that the dial-pad was displayed. After entering a number and pressing "Initiate Call" the status "Dialing xxx xxx xx xx [cancel]" was displayed, but nothing happened. I was able to cancel the call, but I wasn't able to torn off the modem again. I was able to download the morph browser preset, but did not do further testing yet. One thing I noticed, when lowering the brightness to the lowest setting, the screen seems to turn completely off. I was still able to set the brightness back to a level where the screen is visible. So this is only a minor issue. Am I right to assume, that keeping the settings persistent over reboots isn't yet implemented? As I prefer longevity above performance for my phone, I did set "economic" and a relatively low display brightness, but after each reboot they are back to the defaults. I did set the first partition of mmcblk0 to default after expanding it. This worked as flawless as on the PC platform. Regards, Pirmin

Sculpt 22.10 not working on Thinkpad X201
by dogma＠disroot.org 06 Mar '23

06 Mar '23

Image dd'ed to a flash drive, and I checked that vt-d, vt-x, and NX were as they should be. GRUB shows the splash image briefly, the screen goes blank black, something in the computer makes a moderately high-pitched sound for five seconds or so, and nothing more happens.

Trustzone with virt_qemu_arm_v8a
by Devashish Dewangan cs21m017 02 Mar '23

02 Mar '23

Dear Genodians, I am working with virt_qemu_arm_v8a, and I read the extensive documentation on how Genode has experimented with the Trustzone of ARM. I want to explore the Trustzone and run an application in the secure mode, but I wanted to know if it is possible to do with virt_qemu_arm. -- Regards, Devashish Dewangan CS21M017

jitterentropy base genode nstime.h for virt riscv
by Pranab Kumar Rout cs21m045 01 Mar '23

01 Mar '23

Hello all, While building sculpt for virt riscv, I was getting undefined reference errors in app/gpt_write, Based on Norman's suggestions earlier, I updated the recipe for the jitterentopy API [1] that is used to assemble the content in depot/genodelabs/api/jitterentropy/<version>/ [1] genode/repos/libports/recipes/api/jitterentropy/content.mk This helped me overcome the undefined reference errors, But now I am getting: Library jitterentropy COMPILE jitterentropy-base-genode.o COMPILE jitterentropy-base.o genode/depot/genodelabs/api/jitterentropy/2023-02-24/src/lib/jitterentropy/spec/riscv/jitterentropy-base-genode-nstime.h: Assembler messages: genode/depot/genodelabs/api/jitterentropy/2023-02-24/src/lib/jitterentropy/spec/riscv/jitterentropy-base-genode-nstime.h:20: Error: unrecognized opcode `mrc p15,0,a5,c9,c13,0' make[7]: *** [genode/repos/base/mk/generic.mk:58: jitterentropy-base.o] Error 1 make[6]: *** [var/libdeps:112: jitterentropy.lib] Error 2 make[5]: *** [Makefile:336: gen_deps_and_build_targets] Error 2 This error seems be due the contents of the header file (That I had created): repos/libports/src/lib/jitterentropy/spec/riscv/jitterentropy-base-genode-nstime.h because jitterentropy was not enabled yet on riscv, I had to create this file myself. Contents of [2] that I had written: #ifndef _JITTERENTROPY_RISCV_BASE_GENODE_NSTIME_H_ #define _JITTERENTROPY_RISCV_BASE_GENODE_NSTIME_H_ static inline void jent_get_nstime(__u64 *out) { uint32_t t; asm volatile("mrc p15, 0, %0, c9, c13, 0" : "=r"(t)); *out = t; } #endif [2] *repos/libports/src/lib/**jitterentropy/spec/riscv/* jitterentropy-base-genode*-**nstime.h * I tried to build it by looking at the header files corresponding to other architectures. I am not aware of opcode for riscv. Please guide me to write the correct code. what should be written in this header file for riscv. Thanks and regards, Pranab Kumar Rout

Announcement: Genode OS Framework version 23.02 released
by Norman Feske 28 Feb '23

28 Feb '23

I am happy to announce the release of Genode version 23.02. https://genode.org/documentation/release-notes/23.02 With this release, the underpinnings of the recently published first Sculpt image for the PinePhone - like the system-update mechanism and many I/O optimizations - have become part of the regular framework. But the phone is only one among many devices addressed by the new version. For Xilinx Zynq, which lacks an IOMMU, we crafted a custom IP core to attain DMA protection for Genode. For ARMv8, we extended our virtual machine monitor with the device models needed for running regular graphical Linux distributions. And for PCs, the principle kernel mechanism for suspend/resume has become available our custom base-hw microkernel in addition to NOVA. Also the extension of the Goa tool with library support by Pirmin Duss - as discussed recently on this mailing list [1] - made it into the release. As usual, the above summary is merely the tip of the iceberg. The highlights at a glance: - First system image of mobile Sculpt OS (PinePhone) - Interactive graphical VMs on ARM - Custom IP block for DMA protection on AMD/Xilinx Zynq - Optimized GPU and VFS performance - On-target system-update and rollback mechanism - Device-driver improvements for NXP i.MX (USB-C, network) - Distinction of Intel P&E cores on the NOVA kernel - Suspend/resume and improved scheduling for the base-hw kernel - Streamlined work flow for building and publishing libraries The full details are covered by the official release documentation: https://genode.org/documentation/release-notes/23.02 Have fun with exploring the new version!

Availability for riscv64 OS
by Sagar Acharya 27 Feb '23

27 Feb '23

I noticed that there is some support for riscv64. Which kernels and bootloaders are supported for riscv64 based systems. Today, is it possible to build a monocore monoprocess shell based OS with genode? Thanking you Sagar Acharya https://designman.org
