First system image of Sculpt OS for the PinePhone
by Norman Feske 10 Feb '23

10 Feb '23

Hello, I'm happy to announce the first system image of Sculpt OS for the PinePhone: https://genodians.org/nfeske/2023-02-01-mobile-sculpt Thanks to the wonderful team at Genode Labs for having made that possible! Speaking for myself, I'm overjoyed. :-) BTW, I will present this version on Saturday at FOSDEM in Brussels: https://fosdem.org/2023/schedule/event/genode_on_the_pinephone/ For the immediate testing period at the current stage, I am mostly interested in the operation of the modem and the overall robustness. Hence, I would appreciate your responses with testing mobile-data connectivity and voice calls as well as reporting of glaring bugs or annoyances. Regarding the use as daily driver for me personally, I see two blocking issues, which I will tackle next. - A sleep mode that turns off the screen after a few seconds of no interactivity. I think with this change, one battery charge could get us through the day. - A prolonged standby mode that switches off the application processor and keeps the SCP watching the modem for incoming calls and booting the application processor on such events. This will ultimately allow us stay receptive for incoming calls for several days without recharging. Should you like to experiment with building / experimenting / modifying the system, please share your rough direction so that I can supplement further documentation to support you. Wishing you fun with trying out Sculpt OS on the PinePhone! Norman -- Dr.-Ing.

First Rockchip port repo.
by Michael Grunditz 10 Feb '23

10 Feb '23

Hi I have made a github repo for my Rockchip port. It is only RK3588 for now, but I plan to add rk3399 for supporting Pinebook Pro. There are a number of things not working.Most irritating is USB. My old tree had driver in dde_linux repo. Currently if built with drivers-interactive it fails in a couple of library dependencies. If built from a run file it won't build all lx_kit files needed. Feel free to help me, fork and make pull request. There is a crt0.s in the start directory that you can copy to base-hw. I hope it doesn't break things. It is required for this platform, probably because I start genode with "go" and not bootm. I can't get bootm to work. The requirement for running this is a RK3588 board with uboot that support USB and HDMI. You need to run "usb start" before booting. The video driver gets the screen mode from what uboot has configured with EDID. Works just fine with 1080p monitor. But not with a 4k monitor, Well this is it! I have enjoyed it so far. I have tried to being careful with authours by adding myself and kept original developer where appropriate. Please fix if I did something wrong there. It might also be traces from A64 port , which you also can remove if you find any. I also kept the license and base copyright which means that I give this away to The labs. Have fun. The repo: https://github.com/mickenx/genode-rockchip Michael

Goa: build libraries fails on arm_v8a
by Duss Pirmin 07 Feb '23

07 Feb '23

Hello Genodians While extending my tests for the feature to build libraries with Goa, I encountered an error when building a library, that works well on x86_64, for arm_v8a. The error is as follows: /usr/local/genode/tool/21.05/bin/../lib/gcc/aarch64-none-elf/10.3.0/../../../../aarch64-none-elf/bin/ld: ../../lib/libc++.lib.so: The first section in the PT_DYNAMIC segment is not the .dynamic section /usr/local/genode/tool/21.05/bin/../lib/gcc/aarch64-none-elf/10.3.0/../../../../aarch64-none-elf/bin/ld: final link failed: bad value I guess, this is due to some remaining bug in my changes. Other libraries built from the same source tree (using cmake) can be built without error. Searching for the problem, I got [1] and [2]. The first blames binutils, the second is more specific by identifying objcompy. AFAIK objcopy is part of binutils. Has somebody an idea what could cause this error in the Goa case? Could it be, that the wrong version of objcopy is used? The verbose output is as follows (shortened and line breaked for better readability): /usr/local/genode/tool/21.05/bin/genode-aarch64-g++ -fPIC -fPIC -O2 -D__GENODE__ -nostdinc -D__BSD_VISIBLE -D__FreeBSD__=8 -O3 -I/data/.../api/base/2022-09-17/include/spec/arm_64 ... -Wl,-gc-sections -Wl,-z -Wl,max-page-size=0x1000 -Wl,-Ttext=0x01000000 -Wl,--eh-frame-hdr -Wl,-rpath-link=. -Wl,--whole-archive -nostartfiles -nodefaultlibs -static-libgcc -L/data/gapfruit/goa/llvm/var/abi/arm_v8a -lgcc -l:ldso_so_support.lib.a -fPIC -T /home/pirmin/.local/goa/share/goa/ld/genode_rel.ld -shared -o ../../lib/libc++.lib.so CMakeFiles/cxx_shared.dir/algorithm.cpp.obj ... -nodefaultlibs I have already pushed some new commits that fix small things that I discovered during extended testing.

Virt_qemu_arm_v8a replacement of ROM system with RAM system.
by Devashish Dewangan cs21m017 07 Feb '23

07 Feb '23

Dear Genodians, I am working with arm_v8a to run it on qemu. I found out that virt_qemu_arm_v8a doesn't support the ROM system and the solution to it is that I can use the RAM system provided in Genode. Can you guide me to replace the ROM system with the RAM system. Below is the error I got while trying to run the sculpt.img -- Regards, Devashish Dewangan CS21M017

Testing sculpt image on pinephone
by Sagar Acharya 06 Feb '23

06 Feb '23

I flashed an sd card on Pinephone Beta edition 3GB. It booted into GUI nicely I also tried flashing it on internal mmc of 32GB but it doesn't bootup. Has anyone managed to boot up from internal memory? I don't see how it should be any different! Thanking you Sagar Acharya https://designman.org

Running genode on QEMU having board support of raspberry pi for arm_v8.
by DHIRAJ PRAJAPATI 06 Feb '23

06 Feb '23

Dear genodians, As I saw that you already worked on the Raspberry for Genode framework,I wanted to ask about that because I am also working on it. I am trying the port genode having the arm_v8a support of Raspberry board to run that on QEMU. So I need some guidance from you on how to start and what should be the roadmap for generating the boot image (.img file ) having arm 64 architecture which can be booted and run on QEMU. It would be very helpful for me if you guide me to port genode on QEMU for arm_v8a. Regards, DHIRAJ.

Restarting siblings vs. restarting nieces
by Sid Hussmann 06 Feb '23

06 Feb '23

Dear Genodians, I noticed a behavior that I would like to understand. Let's assume we have the following parent-child relationship of a sub-system, omitting some ancestors for simplicity: ``` . └── init ├── fs │ ├── init │ │ └── rump │ ├── fs_mgr │ └── report_rom ├── fs_client1 └── fs_client2 ``` In this example, the config for the first `init` is written via the depot query/deploy mechanism. Thus, `fs`, `fs_client1`, and `fs_client2` are pkg archives. The `runtime` file from pkg archive `fs` contains a management component `fs_mgr` that generates an `init` config which starts a `vfs` server with a `rump` plugin within that `init`. For context, we use the `fs_mgr` to instrument it to start `fsck` or `mkfs` depending on its configuration. But that's not relevant right now. Let's also assume the routing is valid so that `fs_client1` and `fs_client2` are up and running, and they both consume the `File_system` session provided by `rump`. Now to my observation: When I restart `fs` by incrementing its version attribute in the deploy file, `fs`, `fs_client1`, and `fs_client2` all get restarted. That is what I would expect. However, the behavior is different when I instrument the `fs_mgr` to restart `rump`. Most of the time, both `fs_client1` and `fs_client2` don't seem to notice. Is this behavior by design? Is `init` designed to behave differently regarding client/server dependency when siblings get restarted vs. when a niece is restarted? Is there a way to instrument `fs_mgr` to write an `init` config, so that `fs_client1` and `fs_client2` get restarted? Granted, I observed this in a more complex scenario. I once had the following errors when restarting `rump` on `arm_v8a/base-hw`: ``` Kernel: init -> init -> fs_client1 -> ep: cannot send to unknown recipient ... Kernel: Cpu 0 error: re-entered lock. Kernel exception?! ``` Would it make sense for me to create a simplified scenario of it to dig into this behavior further? Kind regards, Sid

vbox6-block: hang in linux kernel boot
by Dan Connolly 31 Jan '23

31 Jan '23

As I mentioned, I got vbox6-block to boot using 4 block devices. It boots grub, and I can transfer control to Ubuntu 22.04. I used recovery mode to get a little more info about what's going on. Then after a bit it hangs. The genode logs show lots of "preemption during measurement" warnings. The linux kernel log shows stuff like... start_kernel+0x49a/0x4ca ... Spectre V2 : ... Filling RSB on VMEXIT ... smpboot: CPU0: Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz ... and then... nothing. suggestions? For more config, logs and a screenshot, see... https://github.com/dckc/madmode-blog/issues/49#issuecomment-1409922456 -- Dan Connolly http://www.madmode.com/

vbox6-block: no policy defined for label 'vbox6-block -> block0'
by Dan Connolly 31 Jan '23

31 Jan '23

I'm struggling to understand how to configure the vbox6-block component. All seems to go well until... [runtime -> ahci-0.part_block] Warning: no policy defined for label 'vbox6-block -> block0' I read up on component configuration; I have a better understanding of it now. https://genode.org/documentation/genode-foundations/22.05/components/Compon… But I don't understand the details of how to configure block services in a launcher. For detailed logs, my launcher config, etc., see: https://github.com/dckc/madmode-blog/issues/49#issuecomment-1407819827 p.s. I got falkon and screenshot working, but in that same issue 49, note problem reports w.r.t - shutdown / acpica - ssh_client - sneakernet (usb_drv) -- Dan Connolly http://www.madmode.com/
