How do I get a component to wait for an RPC method to be called? Can I use
a semaphore, or will that block RPC calls? Do I need a thread dedicated to
handling RPC? If so, should I create a new Rpc_entrypoint and tell it to
manage the Rpc_object?

Currently, Genode's Slave API is designed to create child components and
request services from them. However, it does not allow the parent component
to provide services to the child. Making
Genode::Slave::Policy::resolve_session_request() virtual would fix this.

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?

Update:
I have tried giving usb_drv access to all PCI devices. This hasn't changed
anything.
Also, the AHCI driver still doesn't work, and gives the "sys_assign_pci:
Invalid Hint" errors, but not the Out_of_caps error that usb_drv does.

In Genode, it is common practice to separate everything into small modular
components, especially when dealing with untrusted data. How far can we go
with this before running into performance or memory issues?

it seems to be the most stable. Then, in your vfs configuration, you need
to attach the filesystem somewhere. External filesystems can be attached
much like built-in ones, such as dir, tar, and log. Just add this wherever

Use jitterentropy from libports. You can find an example of how to use it
in wifi.run.

It could be CPU clock cycles. If the CPU has invariant TSC, which seems
very likely given that it's a 4th generation i7, then it's probably
1/1,800,000,000 of a second.

RPC functions often throw exceptions. What exactly happens when these
exceptions are thrown? Most importantly, what happens on the server side?
Does the RPC call just end as soon as the error is thrown, allowing the
server and the session to continue normally?

Thanks. Upgrading Qemu fixed the problem.

I have been working on my fs_filter (vfs-like) component, and it compiles,
but fails to successfully create a File_system::Connection. Even with a ram
quota of 1G, I get the following error:
Uncaught exception of type 'Genode::Allocator::Out_of_memory'
What am I doing wrong? I have tried multiple
I am planning on using gdb_monitor to debug components I write, but it
doesn't seem to work. I have tried all the run scripts, and none of them
succeed at attaching the debugger. I looked for any recent applicable
commits in genodelabs/master, but none of them are more recent than the
16.05 release
I did as you suggested. Here's the commit:

Copy everything from var/run/l4linux to an empty ext2 partition.
Add the following menu entry to grub.cfg:
menuentry 'Genode' {
load_video
insmod legacycfg
insmod part_msdos
insmod ext2
set root='hd1,msdos3'
legacy_configfile /boot/grub/menu.lst
}

In my fs_filter component (much like the vfs server), I am trying to allow
multiple clients fast, non-blocking access to multiple filesystems. To do
this without several threads, my component needs to know when each
filesystem server unblocks so it can send more packets. Unfortunately, the
File_sys
On the error lines, you can try replacing "unsigned" with "const char *".
That should at least fix those errors. If that for some reason doesn't
work, you can replace it with "unsigned long long", but that will make
l4linux no longer compile for x86_32.
