[depot_autoremove] Removing outdated PGKs from the depot
by Alice Domage 12 May '23

12 May '23

Dear Genodians, With the democratization of Goa and the direction we are taking to use it more often in our workflow, we extensively create, upload, download, extract, and deploy PKGs on our devices. Inevitably, we filled up our storage with the depot, most notably on our arm_v8a-based gateway that only comes with 16Gb of eMMC. We need a strategy to clearly define what can be removed from the device and do it accordingly. I have sketched out a plan for implementing this feature and would like your opinion on that. Also, would you be interested in taking this upstream? I want to create a new component, 'depot_autoremove', that would be executed by the 'depot_download_manager' after the 'extract' step as an optional stage. The 'depot_autoremove' component will consume a config, the installation config, to identify a set of packages to keep installed. It will remove any other packages and orphan dependencies not part of that set. That would be the first iteration for this component. You may have already thought about this problem and might have an idea of how to solve it. 1. Is there already an existing solution to this problem that I have overlooked? 2. Is there an alternative approach that you would be more in favour of? 3. What is your opinion on this approach? Best, Alice Domage

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, While building sculpt for virt_qemu_riscv, I found that dde_rump port is not prepared for RISCV.

Works on PinePhone Pro Explorer?
by DeusVult03 23 Mar '23

23 Mar '23

Hello, I have the pinephone pro explorer edition, which is a bit newer and has more features than basic pinephone. It was released a long time before Genode 23.02, however I am not sure if the recent Genode update will work on this hardware. I have been eagerly following Genode in hopes for when it will work on my PCs. Thanks for your feedback and reply, DV03

Hi I am trying to bring up EHCI using the A64 driver. I configiured build system to download a tar ball with linux kernel. However in the: "CONFIG Linux" step I get this: Makefile:621: arch/arm64/Makefile: No such file or directory Which is natural since the source tree in depot isn't configured. So the first questions is; when is the tree configured? Michael

iwlwifi-9260-firmware
by Alice 17 Mar '23

17 Mar '23

Dear Genodians, I am planning on using sculpt on my razer blade 15 from 2015. It was straightforward to boot it. However, wifi networking won't work. After some investigations, only the intel 'iwlwifi-9260-firmware' needs to be included for it to work. I forked 'dde_linux_firmware' [1] and created a pull request [2] to add the firmware and the license. Please let me know if this is appropriate. Finally, I have a branch that implements the necessary changes on the genode repository [3]. It currently uses my fork of 'dde_linux_firmware' in 'dde_linux/ports/linux-firmware.port'. Wifi now works on my laptop. If [2] is correct and accepted. I can adapt those changes if welcome to create a pull request for the genode repository. [1] https://github.com/cnuke/dde_linux_firmware [2] https://github.com/cnuke/dde_linux_firmware/pull/1 [3] https://github.com/a-dmg/genode/tree/iwlwifi-9260-firmware Cheers, Alice

PinePhone Sculpt Build Problems - Almost There
by John J. Karcher 16 Mar '23

16 Mar '23

Hello All, Thanks to Norman's quick response, my PinePhone Sculpt build has progressed a lot further! Now it is breaking on what seems like an easy problem: created genodelabs/pkg/sculpt/2023-03-14 make[1]: Leaving directory '/home/mainuser/Devel/genode_main/genode/build/arm_v8a' Error: sculpt/launcher/report_dump not present in any repository make: *** [Makefile:431: run/sculpt_image] Error 248 I've done some rudimentary poking around to see it I could either remove "report_dump" from the Sculpt configuration or add it, but I don't know enough to accomplish either yet. Could someone give me a quick pointer to how this is configured? Also, any thoughts on why "report_dump" would be "not present"? And while on the topic, the "SCULPT=phone" item of the make command is intriguing - if one wants to create a customized Sculpt variant, how does one go about that? Thanks and Happy Sculpting! -- John J. Karcher devuser(a)alternateapproach.com

PinePhone First Impressions & Questions
by John J. Karcher 13 Mar '23

13 Mar '23

Hello All, I have had my PinePhone running the first Sculpt image for a couple of weeks now. I don't have anything interesting to report beyond what others have said - the system boots in about 5 seconds, the Leitzentrale UI is intuitive and smooth, the battery indicator isn't very accurate, etc. Unfortunately, I also have a problem that seems to be common for various reasons - I don't have data connectivity. In my case, it's because I have a talk/text-only plan, but I can't test the phone functions either because my SIM card (T-Mobile USA) is not recognized. I am itching to try the various presets, and was wondering if any of the following ideas would be feasible: - Providing an on-disk depot for the presets. (Excluding the web browser, which would be useless without connectivity anyway, seems like it would keep the size down.) - Letting us know when the WiFi or wired LAN drivers are ready for testing, even if it's before the next release. (I have the USB network dongle, so either one would work for me.) I am currently having trouble building the PinePhone Sculpt image from source (which I will address in a separate message), but I will be happy to do custom builds if necessary (including for SIM debugging). It just looks like too much fun to wait! ;^) Thanks! -- John J. Karcher devuser(a)alternateapproach.com

PinePhone Sculpt Build Problems
by John J. Karcher 13 Mar '23

13 Mar '23

Hello All, I am trying to build the PinePhone sculpt image from source, using the "First system image of mobile Sculpt OS" Genodians article and the various "README" files as guides. First, I made the recommended changes to "build.conf" (hopefully correctly). When running "make run/sculpt_image KERNEL=hw BOARD=pinephone SCULPT=phone DEPOT=omit", it eventually gives the following error: including /home/mainuser/Devel/genode_main/genode/tool/run/image/uboot including /home/mainuser/Devel/genode_main/genode/repos/allwinner/tool/run/image/pine_uboot_sdcard including /home/mainuser/Devel/genode_main/genode/tool/run/boot_dir/hw including /home/mainuser/Devel/genode_main/genode/repos/gems/run/sculpt_image.run can't read "arg": no such variable while executing "puts stderr "missing run-tool argument: $arg"" (procedure "assert_run_arg" line 4) invoked from within "assert_run_arg "--image-uboot-gzip-best"" (file "/home/mainuser/Devel/genode_main/genode/repos/gems/run/sculpt_image.run" line 34) ... This is too cryptic for me, as I am anything but a build system expert. The following steps may be unnecessary, but I was just trying things that seemed reasonable. Running "prepare_port pine_uboot" worked fine, but "make u-boot/pine BOARD=pinephone" says: checking library dependencies... Program u-boot/pine/pine_uboot /bin/sh: 0: Illegal option -o pipefail /bin/sh: 0: Illegal option -o pipefail /bin/sh: 0: Illegal option -o pipefail make[3]: *** [Makefile:556: /home/mainuser/Devel/genode_main/genode/build/arm_v8a/u-boot/pine/arm_trusted_firmware/sun50i_a64/debug] Error 2 make[2]: *** [/home/mainuser/Devel/genode_main/genode/repos/allwinner/src/u-boot/pine/target.mk:35: /home/mainuser/Devel/genode_main/genode/build/arm_v8a/u-boot/pine/arm_trusted_firmware/sun50i_a64/debug/bl31.bin] Error 2 make[1]: *** [var/libdeps:23: pine_uboot.prg] Error 2 make: *** [Makefile:336: gen_deps_and_build_targets] Error 2 I probably made a configuration mistake or forgot a step (or multiple).

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

Enumerating partitions, then "Error: Aborting: no partition table found."
by dogma＠disroot.org 10 Mar '23

10 Mar '23

Since Sculpt OS 22.10 wouldn't boot for me, I'm using images that Alex kindly made for me in the course of troubleshooting that. In the log, this calls itself "Genode 23.02-24-g23bbbcd8ac <local changes>". Anyway, the hard drive. It's an actual, old-fashioned hard drive, and I've accumulated 21 partitions on it. The log goes like [core] [init -> drivers -> dynamic -> ahci_drv] version: major=0x1 minor=0x300 [core] [init -> drivers -> dynamic -> ahci_drv] command slots: 32 [core] [init -> drivers -> dynamic -> ahci_drv] native command queuing: yes [core] [init -> drivers -> dynamic -> ahci_drv] 64-bit support: yes [core] [init -> drivers -> dynamic -> ahci_drv] number of ports: 6 [core] [init -> drivers -> dynamic -> ahci_drv] #0: ATA [core] [init -> drivers -> dynamic -> ahci_drv] #4: off (unknown device signature) [core] [init -> drivers -> dynamic -> ahci_drv] #5: off (unknown device signature) [core] [init -> runtime] child "ahci-0.part_block" [core] [init -> runtime] RAM quota: 7944K [core] [init -> runtime] cap quota: 66 [core] [init -> runtime] ELF binary: part_block [core] [init -> runtime] priority: 2 [core] [init -> runtime] provides service Block [core] [init -> runtime -> ahci-0.part_block] Partition 1: LBA 40 (119537688 blocks) type: [...] Then, immediately after it's listed them all, giving values that look correct...

base-hw running on a Cortex A7 processor?
by Robert Stewart 09 Mar '23

09 Mar '23

I'm about to start to bring up a base-hw implementation on an Arm Cortex A-7 quad core Allwinner H3 board. Has this already been done by anyone? The A7 is "similar" to the A9 with the addition of LPAE. As opposed to the A9, it has GIC v2 and an SCU with an L2 Cache tightly coupled to it, mean that you can turn on or off the cache and that's all the control you have. It looks like the Cortex A15 implementation already in base-hw would be a good model to follow to get the A7 running. Bob Stewart Get Outlook for Android<https://aka.ms/AAb9ysg>

Porting OpenJDK in Genode.
by YamiNI ReddY 06 Mar '23

06 Mar '23

Dear Genodians, I am writing to you to request your guidance on porting OpenJDK to run simple java programs in Genode. As I have been looking into the possibilities of running OpenJDK on Genode. I have been searching for documentation and resources on the subject, but I have not been able to find any comprehensive guide that explains the process in detail. Could you please guide me on the steps involved in porting OpenJDK to Genode? Additionally, if you know of any resources or documentation that could be useful for me, I would be grateful if you could share them with me. Thank you very much for your time and consideration. Best regards, Yamini

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
