DosBox is DOS-Emulator which is mainly used for playing old
DOS games on POSIX systems and newer Windows versions.
This port of DosBox runs natively on Genode by using its
SDL backend. It is currently only works on x86_*.
Fixes#937.
This patch changes the noux.run script to use the new log_terminal
component instead of an UART driver. Besides being a nice way to test
the log_terminal service, the new version is much simpler and it just
became compatible to Linux as it no longer relies on an UART driver.
Issue #947
This patch adds a 'gdb' command to 'cli_monitor', which makes it possible
to debug an application with GDB.
The command works similarly to the 'start' command, but instead of
starting the subsystem binary directly, an 'init' subsystem gets
started, which then starts 'terminal_crosslink', 'noux', GDB and
'gdb_monitor' (which starts the application binary as its target).
So, for the 'gdb' command to work, these additional components need to
be available, too. 'terminal_crosslink', 'noux', 'gdb_monitor' and the
file 'gdb_command_config' are expected to be ROM modules. The Noux GDB
client needs to get mounted at '/bin' in Noux and the target binaries need
to be available as ROM modules (loaded by 'gdb_monitor') and also mounted
at '/gdb' in Noux (loaded by the GDB client).
Additionally, the source code of the target application can be provided
at '/gdb/src/ in Noux. How the Noux mountings get established can
be configured in the 'gdb_command_config' file. The default configuration
in 'os/src/server/cli_monitor/gdb_command_config' mounts GDB from a tar
archive named 'gdb.tar', the GDB target binaries from a tar archive named
'gdb_target.tar' and the target source code from a tar archive named
'gdb_target-src.tar'.
The patch includes an 'expect' include file (ports/run/noux_gdb.inc)
which provides functions that help to create those tar files:
- 'create_gdb_tar' creates a tar archive for the 'gdb' client
- 'create_binary_tar' creates a tar archive for the target application
- 'create_source_tar' creates a tar archive for the source code of
the target application
- 'create_binary_and_source_tars' is a convenience wrapper for the previous
two functions
The patch also includes an example run script
(ports/run/noux_gdb_dynamic.run).
The 'gdb' command supports the following command line options:
- --ram: the initial RAM quota provided to the whole subsystem
(including the GDB-related components)
- --ram-limit: limit for expanding RAM quota
- --gdb-ram-preserve: the RAM quota that 'gdb_monitor' ahould preserve
for itself
Fixes#928.
This patch implements the POSIX signal functionality needed to interrupt a
running Noux GDB by pressing 'Ctrl-C'.
It allows to register a signal handler for the 'SIGINT' signal, which
gets executed after 'Ctrl-C' is received from the terminal. With the
current state of the implementation, the signal handler only gets executed
when the Noux application calls a 'read()', 'write()', 'ftruncate()' or
'select()' syscall.
Fixes#923.
* Remove far too low default values from Nic::Connection constructor
* Extend lwip initialization function with desired TX/RX buffer sizes
* Add configuration possibility to libc_lwip_dhcp plugin to define
buffer sizes, like the following:
'<libc tx_buf_size="1M" tx_buf_size="1M"/>'
Fixes#892
Statically configured NIC bridge clients must be configured via
<policy...> nodes in the config. Otherwise, the bridge can't answer ARP
requests or route traffic.
This patch updates the launchpad config to use XML attributes and
removes the built-in default configuration (which is only meaningful
for demo.run anyway).
The netperf test configures the target Genode system for with
10.0.2.55/24. Also, nic_drv on base-linux uses the virtual ethernet
device 'tap0', which must be configured for the test user and network
address 10.0.2.1/24 on the test host like follows.
tunctl -t tap0 -u <user running test>
ip address add 10.0.2.1/24 dev tap
ip link set tap0 up
This patch moves the GDB commands to set a breakpoint in the 'main()'
function into a separate file that can be included from other run scripts.
Fixes#876.
If the path of a Genode source file (as extracted from the binary test
application) contains a part like '/a/b/../' where '/a' exists, but '/a/b'
does not exist anymore, 'tar' complains. With this patch, the run script
normalizes the path before calling 'tar'.
Fixes#875.
Don't account the boottime to the actual compile time - since it varies quite
a lot if somebody else utilize the network with lwip tests for example ;-).
Split the netperf run script into 3 ones so that it can be used more easily
in an automated run.
netperf.run - use native nic driver (x86) or usb2.0 (arndale, panda)
netperf_usb30.run - use native nic driver (x86) or usb3.0
netperf_bridge.run - use native nic driver (x86) or usb3.0 (arndale) and bridge
Issue #794
Sometimes the ports are not freed up quick enough by the host system after the
first test finished. The port restriction is mainly required for qemu, so don't
use it for bare metal hardware tests.
lwip reports via getsockopt the size of the default size of the receive buffer
to the netperf server. lwip returns 2GB and netperf server uses this value to
allocate some buffers - which of course fails with out of memory.
Reduces the "default size" to some smaller value.
With the commit we are not forced anymore to (but still can) use specific
netperf client options regarding memory allocations of the receive buffer.
MAERTS is STREAM backwards and effectively lets the netserver sends the packets
to the netperf client. So, TCP_STREAM measure the receive performance of the
lwIP stack on Genode and TCP_MAERTS the send performance of the lwIP stack
on Genode.
With this patch, 'liquid_framebuffer' can be reconfigured at runtime.
The configuration arguments are now provided as XML attributes, matching
those for 'nit_fb'. Furthermore, two new configuration options are added:
<config ...
resize_handle="off" - show/hide a resize handle widget in the lower
right window corner
decoration="on" - show/hide window decoration
(title bar and borders)
/>
