This is a change that has some potential challenges. If the driver simply

As an update, I think I understand why the rt2x00 version cannot recover
from the rfkill block. In addition to flushing the USBs tx queues, it also
flushes the rx queue, which calls usb_kill_urb. I have emulated that

Hello,
I'm trying to configure my usb driver to accept multiple possible
vendor/product combinations. I found the component usb_report_filter, which
as I understand consumes a usb devices report, and produces a usb
configuration file with a matching policy and a report that my component
can use
Update: I was able to get the rt2x00_usb driver to work[1][2]. I ended up
simply forcing a call to unblock_time_handler() before ever running the
linux scheduler. The driver can associate to networks (at least mine) and
serve the test page when run under the test scenario, and it can download

I was able to re-factor the usb emulation to prevent re-entrant scheduling.

Hi Johnny,
What I said is, I don't think you can run Sculpt effectively on such
small screens right now. When using an emulator I always set the screen
size to something big enough - this depends on the emulator but there are
tricks, at least with qemu.

Last year was a good year in Genode for me. I poke around with it at the
hobby level, but this year I saw the drivers system substantially re-worked and

Yes, I have gotten it to work on 64-bit x86 Mac mini (probably a bit more

Will, You can see the firmware whitelist here: repos/pc/src/lib/wifi/firmware.cc. It seems to request firmware that isn’t on the list. Presumably this means your wifi card is a slightly different model from others, but it might still work with the firmware. If you are building Sculpt from source
Hi Will,
I can offer a fellow-user perspective on this, but I’m sure the Genode
developers can say more.

Thanks for this, and also thanks to Cedric for the "unofficial" guide.

As a hobbyist who's been following Genode for about a year now (I was

don't expect to be influential in any serious way, but perhaps t
Hello,
I just upgraded to the 20.08 version of Sculpt. There seems to be a
problem with the boot_fb_drv component, from what I can guess the changes
to this component because of the graphics refactor make it need more RAM,
but the driver_manager computes the ram as "_pitch * _height + 512*1024"

Hello,
I am having a lot of fun with Sculpt, but I do wonder something about
copy/paste. Whenever I copy a large portion of text, a subsequent paste
only gives the first part. This is most noticeable within a VM, but I
wonder, since the VM can move the clipboard to/from Sculpt, if a Sculpt

If you want to try it, I have had success using fb_boot_drv instead of

Hello,
I am new to Genode/Sculpt and have been trying to get it working on my
somewhat old Mac Mini. I eventually succeeded to make it boot, by disabling
some unnecessary drivers like PS2. However, wifi doesn't work, and I would
like that feature. There is an internal wifi card in the computer t
