Failure of Genode Demo
by zabarnyi＠campus.technion.ac.il 04 Jun '18

04 Jun '18

Hello, This is my first experience with Genode. I am trying to run a demo for Genode 17.05 (with toolchain 17.05, 64 bits), on an Oracle VM VirtualBox (5.2.10-122406) virtual machine, with Linux Ubuntu 16.04.4 (64 bits) OS. I am following the guide on https://genode.org/documentation/developer-resources/getting_started and I have already installed all the packages mentioned in this guide. However, when I try to run a demo using: cd build/x86_64 make KERNEL=linux run/demo the build of Genode succeeds, but the demo fails with the following error message: genode build completed using 'core-linux' as 'core' using 'ld-linux.lib.so' as 'ld.lib.so' using 'linux_timer_drv' as 'timer' spawn ./core Genode 17.05 17592186044415 MiB RAM and 8998 caps assigned to init Warning: blocking canceled in entrypoint constructor Error: Unexpected call of 'block_for_signal' (/genode/genode-17.05/repos/base/src/core/signal_receiver.cc:39) I would be grateful if you could help me to understand the reason for it (I couldn't find the answer on the web). Best regards, Konstantin

package dependencies
by Stefan Thöni 01 Jun '18

01 Jun '18

Hi, I ran into a problem when a genode package (pkg) was named both in parent pkg and it's child pkg like this: pkg/A/archives: _/pkg/B _/pkg/C pkg/B/archives: _/pkg/C pkg/C/archives: _/src/D When creating A, make complained of "recursive package dependency" but I'm sure there is no recursion. I then checked tool/depot/mk/dependencies.inc, 121L which yields that error and it looks to me as that code would always detect a paket named twiced in the dependency graph as recursive dependency. Is this intended? And if so, how should we deal with it?

Shared folder in Sculpt
by Pirmin Duss 24 May '18

24 May '18

Hello The shared folder mounted in to the virtual machine of sculpt always reports the following data to the df command in the VM: size: 512M free: 512M used: 0 Because of this the file manager will not copy any files larger than 512M to the shared Folder, on the console it is possible though. Best regards, Pirmin

Errors when adding part_blk to sculpt scenario
by Boris Mulder 17 May '18

17 May '18

Hello, In an experiment I tried making some modifications to sculpt on staging, most notably moving the file system stack onto the bottom-level init. However, opening block sessions with the drivers subsystem fails. Simply said, if I add another part_blk component to sculpt.run as a child of init, and try to connect its Block-session to the drivers subsystem, I get the following error: |Error: init -> drivers: attempt to transfer initial quota|| ||Warning: PD (init -> drivers) RAM limit (used=776K, limit=1089025) exceeded during transfer_quota(4207020)|| ||[init] child "drivers" requests resources: ram_quota=4207020|| ||Error: init -> drivers: attempt to transfer initial quota|| ||Warning: PD (init -> drivers) RAM limit (used=776K, limit=1089025) exceeded during transfer_quota(4207020)|| ||[init] child "drivers" requests resources: ram_quota=4207020|| ||Error: init -> drivers: attempt to transfer initial quota|| ||Warning: PD (init -> drivers) RAM limit (used=776K, limit=1089025) exceeded during transfer_quota(4207830)|| ||[init] Warning: part_blk: could not revert session RAM quota (service=Block cid=6 args='tx_buf_size=4194304, cap_quota=5, label="part_blk -> ", ram_quota=4207830, diag=0' state=SERVICE_DENIED ram_quota=4207830, cap_quota=5)|| ||[init -> part_blk] Error: Block-session creation failed (ram_quota=4208640, cap_quota=5, tx_buf_size=4194304, label="")|| ||[init -> part_blk] Error: Uncaught exception of type 'Genode::Service_denied'|| ||[init -> part_blk] Warning: abort called - thread: ep|| ||[init] child "part_blk" exited with exit value 1| When I run part_blk in the normal fs runtime with fs.config and default_fs_subinit.config (with part_blk not commented out), it works fine. Of course I do not run both at the same time, as the ahci_drv only supports one client at a time. The config snippet I added to sculpt.run just below the drivers init looks as follows (I copied it from default_fs_subinit.config except that my computer has an MBR partition scheme): | <start name="part_blk" caps="100">|| || <resource name="RAM" quantum="10M"/>|| || <provides><service name="Block"/></provides>|| || <config use_gpt="no">|| || <policy label_prefix="vfs" writeable="yes" partition="1"/>|||| || </config>|| || <route>|| || <service name="Block"> <child name="drivers" label="default"/> </service>|| || <any-service> <parent/> </any-service>|| || </route>|| || </start>| I tried giving part_blk more RAM, giving "drivers" more RAM, giving "drivers -> dynamic" more RAM and giving "drivers -> dynamic -> ahci_drv" more as well (by editing the driver_manager), but the error message persists with the same numbers as above. Now I'm stuck on why this error occurs. One possibility is that the driver_manager has not yet loaded the correct policies for the ahci_drv or the config of the subinit and that it has updated them when I change the runtime config to run part_blk. However, I get no other errors, while I would have expected "no matching policy" or "no route" in that case. I tried creating a clean run script with only the drivers_managed-pc package and part_blk inside it. It gives me the same error so it seems to be related to the drivers_managed-pc subsystem. When I run all those drivers directly on top of init, I do not get the error. Can anyone explain what is going on? -- Met vriendelijke groet / kind regards, Boris Mulder Cyber Security Labs B.V. | Gooimeer 6-31 | 1411 DD Naarden | The Netherlands +31 35 631 3253 (office)

*genode-main mailing list changes*
by Stefan Kalkowski 14 May '18

14 May '18

Dear Genode list subscribers, for quite some time, we thought about moving our mailing list away from Sourceforge. The inability to turn of advertisement, the automated mass-unsubscription Sourceforge proceeded last year, and most importantly: mails were not processed for days frequently. Therefore, we have installed our own mailing list infrastructure at lists.genode.org. Unfortunately, it is impossible for us to gain the currently subscribed users of this list. That is why, we cannot simply portage your e-mail addresses from one list to the other. We like to encourage you to subscribe to the new list at your earliest convenience, here: https://lists.genode.org/listinfo/users >From now on, postings shall be done to the new list's address that is: users@...568... The mail archive is now located at: https://lists.genode.org/pipermail/users/ The current "genode-main" mailing list will get turned off at Monday, May 14, 2018. We apologize for the inconvenience! Best regards Stefan -- Stefan Kalkowski Genode labs https://github.com.skalk | https://genode.org

Genode + ARM + OpenOCD
by Hinnerk van Bruinehsen 14 May '18

14 May '18

Hello, I'm writing/porting a bunch of device drivers for an ARM board (am335x based) for Genode/seL4. I have an on chip debugger (flyswatter2) and can halt or resume the board's operation via the OCD (so generally it seems to work). Since you have successfully ported/written drivers for other boards (imx6 for example), I've asked myself if you have some hints, that may help me to get gdbi (ideally with OpenOCD) working. Right now my problem is that I don't know what binary file I should open gdb with, since using the resulting uimage file doesn't work for me. If someone has some hints for me it would be greatly appreciated! Have a nice holiday and presumably long weekend! WKR Hinnerk
