Both, client and server now read their IP config from their Genode config.
Furthermore, the client now waits 4 instead of 2 seconds before sending the
first request to prevent connection fails in tests with a slow startup. The
client truncates its packet dump for better readability.
Ref #114
This patch adds the missing exception handling for depleted RM session
quotas. If core runs out of session quota while creating a new region
map, it now reflects this condition as a Region_map::Out_of_metadata
exception to the RM client. Thanks to Denis Huber for reporting the
issue!
Although the driver makes no use of interrupts it references Irq_handler
for unknown reasons. Moreover, this commit eliminates the lock that is
not necessary anymore, because the driver now runs single-threaded.

Issue #2060
This patch revives our ds_ownership test from 2012, which just revealed
a regression in core where the dataspace-free operation of the RAM
service would unconditionally destroy dataspace objects from foreign
sessions. The patch fixes the bug and adds an updated version of the
test to the autopilot.
Fixes#2065
The main feature for this version upgrade is the use of the instruction
emulator (IEM) to speed up execution and less often the slow recompiler.
issue #2059
Besides adapting the components to the use of base/log.h, the patch
cleans up a few base headers, i.e., it removes unused includes from
root/component.h, specifically base/heap.h and
ram_session/ram_session.h. Hence, components that relied on the implicit
inclusion of those headers have to manually include those headers now.
While adjusting the log messages, I repeatedly stumbled over the problem
that printing char * arguments is ambiguous. It is unclear whether to
print the argument as pointer or null-terminated string. To overcome
this problem, the patch introduces a new type 'Cstring' that allows the
caller to express that the argument should be handled as null-terminated
string. As a nice side effect, with this type in place, the optional len
argument of the 'String' class could be removed. Instead of supplying a
pair of (char const *, size_t), the constructor accepts a 'Cstring'.
This, in turn, clears the way let the 'String' constructor use the new
output mechanism to assemble a string from multiple arguments (and
thereby getting rid of snprintf within Genode in the near future).
To enforce the explicit resolution of the char * ambiguity, the 'char *'
overload of the 'print' function is marked as deleted.
Issue #1987
Core on seL4 is configured to run on native hardware, so some static
allocators are bit over dimensioned. Some run scripts fail on qemu because
solely 64M are available in the system - adjust the affected scripts.
Issue #2044
The initial support reports TouchPointPressed, TouchPointMoved, and
TouchPointReleased for multiple touch points, but is currently only
tested with widgets not leveraging multi-touch events. In other words, I
made sure synthetic mouse events are generated properly when using touch
screens.
We now always run the input_merger as Input service provider and
configure backends suitable for the used platform. On x86 hardware, we
enable both, PS/2 and USB HID.
Required to boot on hardware. The fragmentation is such unfortunate with the
old allocator that alloc() will throw an exception during very early core boot
phase.
Issue #2044
- disable iommu
- increase root_cnode further for native boot
- support vesa driver on native hardware
- don't mask edge triggered ioapic irqs
- increase various allocators to get noux_tool_chain_* booting natively

That seems nowadays the right place in order to tell the caller that the
thread couldn't be completely constructed. The return value false of
bind_thread causes in Cpu_thread_component the throwing of
Thread_creation_failed.
thread.run now passes
pthread.run now passes
Issue #2044
Additionally, exclude boot-module from page_table_registry. Core does not use
the boot-modules inside core.
Adding it otherwise to the registry will use up the meta data allocator of
the page_table_registry in core in scenarios with lot of boot modules,
e.g. noux and friends.

Now, we support multi-touch devices generating multi-touch events and
absolute-pointer devices simultaneously with multitouch="yes". Still,
multitouch="no" generates emulated absolute-pointer events for
multi-touch devices.
Add option to load the initial overlay*.vdi from disk, but keep the changes
in a ram_fs.
Used with AHCI model for vbox_auto_win7. Currently we have no way to tell
rump_fs to unmount and write back data to disk before resetting the machine.
On MVM only the initial scanning of APs works. If wpa_supplicant changes
from triggered scans to the scheduled-scanning hardware feature no
further scan results are reported. Therefore, we disable the
scheduled-scanning hardware feature until the issue is fixed.
Issue #2046
When running the same kernel in a VM as on the host system and the
kernel boot message from the VM appears on the log output, the run tool
assumes that the host machine has rebooted unexpectedly. With this
commit, an unexpected reboot is assumed only if the kernel boot message
appears at the beginning of a line. On base-hw, we enforce a line feed
at the beginning of the boot message as the SPIKE emulator log starts
with the first message of the kernel lacking a line feed.
Fixes#2041
Thread stacks with less than 4K usable space are insufficient for our
implementation of Linux exception signal handling. If such a unusually
small stack overflows the SIGSEGV handler will not be able to print the
diagnostic message leaving no hint of the cause of the stuck process.
The linker scripts are known to reside in BASE_DIR. By using them
directly from this location instead of searching them in the
REPOSITORIES, we don't need to specify the repos/base as a repository in
order to link.
This patch handles x86_32 and x86_64 separately since this is the SPEC
value directly supplied to the package build tool. This way, we achieve
that a CROSS_DEV_PREFIX is defined for each supported argument.
This patch adds the methods 'sigh_ack_avail()' and
'sigh_ready_to_submit()', which are needed to build asynchronously
operating file-system clients.
Fixes#2023
Those headers implement a platform-specific mechanism. They are never
used by components directly.
This patch also cleans up a few other remaining platform-specific
artifact such as the Fiasco.OC-specific assert.h.
Issue #1993
Conveying the ROM filename as the final label element simplifies
routing policy and session construction.
Annotations by nfeske:
This commit also changes the ROM session to use base/log.h instead of
base/printf.h, which produced build error of VirtualBox because the
vbox headers have a '#define Log', which collides with the content of
base/log.h. Hence, this commit has to take precautions to resolve this
conflict.
The commit alse refines the previous session-label change by adding a
new 'Session_label::prefix' method and removing the use of 'char const *'
from this part of the API.
Fixes#1787
Session_label constructor now takes a bare string rather than a
serialized argument buffer.
Replace all instances of previous constructor with 'label_from_args'
function.
Issue #1787
This patch establishes the sole use of generic headers across all
kernels. The common 'native_capability.h' is based on the version of
base-sel4. All traditional L4 kernels and Linux use the same
implementation of the capability-lifetime management. On base-hw, NOVA,
Fiasco.OC, and seL4, custom implementations (based on their original
mechanisms) are used, with the potential to unify them further in the
future.
This change achieves binary compatibility of dynamically linked programs
across all kernels.
Furthermore, the patch introduces a Native_capability::print method,
which allows the easy output of the kernel-specific capability
representation using the base/log.h API.
Issue #1993
This patch alleviates the need for a Native_capability::Dst at the API
level. The former use case of this type as argument to
Deprecated_env::reinit uses the opaque Native_capability::Raw type
instead. The 'Raw' type contains the portion of the capability that is
transferred as-is when delegating the capability (i.e., when installing
the parent capability into a new component, or when installing a new
parent capability into a new forked Noux process). This information can
be retrieved via the new Native_capability::raw method.
Furthermore, this patch moves the functions for retriving the parent
capability to base/internal/parent_cap.h, which is meant to be
implemented in platform-specific ways. It replaces the former set of
startup/internal/_main_parent_cap.h headers.
Issue #1993
The static 'Thread::mystack()' function returns the stack boundaries of
the calling thread. It is useful when a thread uses a diffent stack than
the primary one.
Fixes#2037
When calling 'connect()' in nonblocking mode and the connection has been
established, don't call 'tcp_connect()' again, which would trigger an
assertion with the message 'tcp_connect: can only connect from state
CLOSED'.
Fixes#2039
In addition to modernizing the component now also supports using
empty RAM dataspace as backing store.
For example to use an ISO file the component has to be configured
as follows:
! <config file="image.iso" block_size="2048"/>
To use a empty RAM dataspace that is 256MiB large and has a block
size of 4KiB the configuration looks like this:
! <config size="256M" block_size="4096"/>
Either 'size' or 'file' has to specified. If both are declared the
'file' attribute is soley evaluated.
Issue #1987.
Fixes#2031.
Use quota large enough so that the USB driver does not attempt to
request further memory. On the Raspberry Pi, init has no slack memory
to respond to such a request.
Pass both paths, absolute path to the mount point and the relative path
from the mount point to the file, along with an open handle rather than
just an absolute path. Otherwise, fstat fails if the addressed file is
implemented by another VFS plugin.
Fixes#1789
Move Genode/vbox memory configuration check to separate
genode_check_memory_config() function and call it in platform-specific
setup machine hook of accloff/nova.
The rationale for this change is to omit the check on Muen since the
guest memory is separate and not allocated from base-hw memory.
Issue #2016
Write tick count of next kernel timer to the guest timed events page if
present. This causes the guest VM to be preempted at the requested tick
count and ensures that the guest VM can not monopolize the CPU if no
traps occur.
The base-hw kernel expects a configured switch-event from the guest VM
to base-hw with ID 30 and target vector 32 to be present in the system
policy.
Issue #2016
Switch kernel timer driver to timed event interface. The base-hw kernel
expects a configured self-event with ID 31 and target vector 32 to be
present in the system policy.
ssue #2016
Add call to genode_setup_machine prior to machine registration in
frontend machine setup code. This enables platform-specific adjustments
to the machine instance.
The new function is used on hw_x86_64_muen to clamp the processor count
to 1 as multiple virtual CPUs are not supported on this platform.
