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).
Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.
binary_ds cap is attempted to free up twice by
_root_dir->release(_name, _binary_ds) in ~Child de-constructor and by
Static_dataspace_info _binary_ds_info de-constructor.
This commit keeps all binary related information inside a struct which gets
freed up after all noux session book keep cleaning is done.
Issue #485
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 ;-).
At least 64bit Seoul dies with Region_conflict reliable and reproducible.
When during startup of Seoul some Genode code (caused by executing some
constructors) try to attach a region, the region manager code in the rm_session
will try to place the attachment at the smallest large enough aligned free
virtual region.
For now, I observed one attachment causing trouble (but not knowing who causes
this - it does also not really matter). The questionable region is 0x4000 of
size for 32bit and 0x8000 of size for 64bit.
To steer the region manager a bit, we try now following trick:
With this commit the load address of the binary for 32 and 64 bit is moved
close to the end of the virtual address space, but leaving enough free virtual
space for the above observed attachment (and a bit more).
The region manager code now will try to fill up the virtual region behind
the binary up to the end of the virtual address space, effectively letting the
lower virtual region untouched - hopefully.
Works for now, but it will break again - for sure.
Fixes#519
If a script is executed which uses a interpreter that does not exist the
construction of the child fails and potentially leaks memory because the
wrong delete operator is called.
Therefore the binary dataspace of the script and the binary dataspace of
the interpreter are now checked before a new child will be created.
Fixes#812.
This patch extends the 'Parent::session()' and 'Root::session()'
functions with an additional 'affinity' parameter, which is inteded to
express the preferred affinity of the new session. For CPU sessions
provided by core, the values will be used to select the set of CPUs
assigned to the CPU session. For other services, the session affinity
information can be utilized to optimize the locality of the server
thread with the client. For example, to enable the IRQ session to route
an IRQ to the CPU core on which the corresponding device driver (the IRQ
client) is running.
This patch introduces new types for expressing CPU affinities. Instead
of dealing with physical CPU numbers, affinities are expressed as
rectangles in a grid of virtual CPU nodes. This clears the way to
conveniently assign sets of adjacent CPUs to subsystems, each of them
managing their respective viewport of the coordinate space.
By using 2D Cartesian coordinates, the locality of CPU nodes can be
modeled for different topologies such as SMP (simple Nx1 grid), grids of
NUMA nodes, or ring topologies.
