The old variant provided 8K capability slots to all processes on core, which increased binaries by 180 KB for the static allocator. I reduced it to 4K capabilities stay under 100 KB overhead for the allocator. Anyway, pci_drv and pl11x_drv need more RAM quota now: 2M for pl11x_drv and 1M for pci_drv.

# \brief Example for debugging a service
|
|
# \author Norman Feske

# \date 2011-09-13
|
|
#
|
|
# This example shows how GDB monitor can be used to debug a Genode service.
|
|
# GDB monitor sits in between the service and the service's parent. Any
|
|
# service announcements are transparently propagated through the GDB
|
|
# monitor to the parent. This way, the internal state of a service can
|
|
# be observed at any time via a remote GDB connection. In the example,
|
|
# the remote GDB connection is realized via an UART device. Alternatively,
|
|
# 'tcp_terminal' could be used (to attach GDB via a network connection).
