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

interrupts on AMD hardware
by Nobody III 06 May '18

06 May '18

Has anyone gotten any Genode drivers to work on computers with AMD processors? The only one that I've gotten to work was fb_drv, which doesn't need to receive interrupts. The other 2 drivers that I've tried recently, usb_drv and ahci_drv, both hang. Has anyone had better compatibility here?

remaining issues
by Nobody III 06 May '18

06 May '18

There are some remaining issues that should be fixed before the 18.05 release, but aren't receiving much attention: init requires double quotas when running under sequence #2755 <https://github.com/genodelabs/genode/issues/2755> (init should request quota upgrades when needed) nit_fb: add optional transparency #2728 <https://github.com/genodelabs/genode/issues/2728> (less important, but just needs to be merged) Framebuffer has_alpha() function #2723 <https://github.com/genodelabs/genode/issues/2723> Noux: rmdir dir/ (trailing slash) does not work #2686 <https://github.com/genodelabs/genode/issues/2686> Multiple rump-backed file-systems not supported by VFS library #2681 <https://github.com/genodelabs/genode/issues/2681> Additional pixel format support #2045 <https://github.com/genodelabs/genode/issues/2045> (important for a library i'm writing; just needs to be merged) All of these should be fairly easy fixes, and at least 2 already have patches that just need to be merged.

Closing laptop lid disables nitpicker focus/input functions
by Boris Mulder 04 May '18

04 May '18

Hi all, I experienced an issue while closing the laptop lid on some hp840 machines. I know you have not tested these laptops, but the behaviour is really curious, so maybe you know better what might be going on. * I am running the sculpt scenario from staging. Everything works fine, until I close and open the lid of the laptop. * When I reopen it, the current focused window still does its job. However, when I switch the focus, for example by triggering the leitzentrale on and off by pressing F12, nothing happens. * I tried setting the report_rom to verbose. It shows the global_keys_handler -> leitzentrale report is not updated by pressing F12. However, in my leitzentrale window which is still active I can type things, execute programs and view the log. * This happened when the leitzentrale was on before I put the lid down and up. * When I put the leitzentrale off and focus my runtime (which is just the fs runtime with a noux shell) before closing and opening the lid, it also cannot change the focus and only the client that was focused before closing the lid (the noux shell) receives input. F12 again does nothing. * In fact I tried it with more complicated runtimes and all the time only the component which had focus (in this case the leitzentrale) still works, the other components cannot get focus or input events. * Report_rom does not give me a focus-, hover-, or any other report when I press a global key, hover over or click on any component, including the focused component. For example, when I have leitzentrale active, the log does not show any report updates when I click or move the mouse. Starting and stopping a runtime works fine, and the runtime gives a nice focus report (if I had focused that runtime before). But pressing F12 does not disable the leitzentrale_enabled flag (or gives any useful output). * It happens both with the intel_fb_drv and the vesa driver. It does not happen on a lenovo x250. Somehow it seems that nitpicker fails to detect any input events (whether from a USB device or the embedded ps2 pad+keyboard), though it forwards those events that belong to the focused client correctly. What could cause this? What happens in the Genode components in the GUI stack when the lid is opened or closed? When I run linux on that laptop I can close and open it just fine. -- 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)
