When the 'Mtd::FPU' flag is set during the registration of a
virtualization event handler, it must also be set whenever the event
handler returns.
Fixes#1283
This patch ensures that priority values passed as session arguments
are within the valid range of priorities. Without the clamping, a child
could specify a priority of a lower priority band than the one assigned
to the subsystem. Thanks to Johannes Schlatow for reporting this issue.
Fixes#1279
This is just a quick fix to calm down the buildbot - a revised
implementation is needed according to issue #1277. Further, the reason
for the increased test duration on several platforms must be
investigated.
The alias is rather Linux-specific and also prevents particularly
tailored jiffies implementations. For the existing dde_linux ports (usb
and lxip) we just define jiffies to be dde_kit_timer_ticks with a
preprocessor macro.
The menu view generates a simple dialog of widgets and reports the
hovered element. It is meant to be embedded into applications that
require simple GUIs but don't want to deal with the pecularities of
a full-blown widget set.
The new 'session_control' function can be used to perform operations on
the global view stack that span one or multiple sessions, e.g., bringing
all views of specific sessions to the front, or hiding them.
If the Rom_session::update function returns false, the ROM dataspace may
have been physically destructed (and core has removed all mappings).
In this case, we have to omit the detach operation in the destructor
of 'Attached_dataspace' to avoid detaching the same region twice.
The headers 'texture_rgb565.h' and 'texture_rgb888' contain
template specializations needed for using the 'Texture::rgba' function
for the respective pixel formats. The specializations were formerly
contained in application-local code.
This patch add an optional alpha argument to the constructor, which may
be passed to a pixel type representing an alpha channel. Furthermore,
a new overload of the mix function has been added to accommodate use
cases where one texture is applied to both a pixel surface and an alpha
channel.
When X-ray mode is active, nitpicker filters motion events that are not
referring to the currently focused domain. However, domains configured
as xray="no" (such as a panel) need to obtain motion events regardless
of the xray mode. This patch relaxes the motion-event filtering to
accommodate such clients.
The buffer offset was wrongly accounted for. The miscalculation went
unnoticed until now because the buffer offset was apparently never used
in combination with alpha-channels.
If a domain is configured as xray="no", we want to let the views of the
domain respond to input events like in flat mode, even if xray mode is
active. Normally, the input mask of views with an alpha channel is
disregarded in X-ray mode. However, for non-ray views, the input mask
should always be considered.
The 'Signal_rpc_member' takes care about dissolving its signal context
from the receiver. So we don't need to manually perform this operation
in the session destructor.
With this patch, the VESA driver chooses the video mode with the highest
resolution from the list of available modes if no resolution is
explicitly configured.
Fixes#1263.
* use seoul branch containing vbios emulator
* report the memory model in the VBE mode info as otherwise the
Genode framebuffer driver will ignore this mode
Fixes#1261
It turned out that the controller configuration can change during the self
tests, so now it is read before running the tests and restored afterwards.
Fixes#1260.
This component merges the input events of multiple sources.
Example configuration:
<start name="input_merger">
<resource name="RAM" quantum="1M" />
<provides>
<service name="Input" />
</provides>
<config>
<input label="ps2" />
<input label="usb_hid" />
</config>
<route>
<service name="Input">
<if-arg key="label" value="ps2" /> <child name="ps2_drv" />
</service>
<service name="Input">
<if-arg key="label" value="usb_hid" /> <child name="usb_drv" />
</service>
<any-service> <parent /> <any-child /> </any-service>
</route>
</start>
For each 'input' config node, the component opens an 'Input' session with the
configured label. This label is then evaluated by 'init' to route the session
request to a specific input source component.
Fixes#1259.
* When flushing the data and unified cache on ARM, clean and invalidate
instead of just cleaning the corresponding cache lines
* After zero-ing a freshly constructed dataspace in core, invalidate
corresponding cache lines from the instruction cache
The backend allocator for the slab is a sliced heap, which hands out
allocations with page-size granularity (4096 bytes). Therefore, the
slab-block size should also be about a multiple of the page size minus
some bytes of overhead.
Additional adjustments:
- The slab-block size and the default quota-upgrade amount for SIGNAL
sessions depends on the platform bit width now.
- The signal test also stresses the case of many managed context in one
session including creation and destruction of the used signal receiver
in repeated rounds.
- correctly catch and report non-existing root directories
- remove *all* leading slashes from root-directory attributes and
sanitize empty declarations to current working directory
The weak implementation was added for quite special purposes years ago
and is no longer needed. On the other hand, the weak attribute does not
help if the implementation ends up in a shared library, which first
resolves symbols locally before asking ldso (that includes the acutal
thread library) *shiver*
The original git:// URL produced the following error:
Cloning into 'jbig2dec'...
fatal: remote error: access denied or repository not exported: /jbig2dec.git
Before the pointer handling was removed from the nitpicker server, the
pointer was always the first view, which was skipped in the find_view
function. However, since we support pointer-less operation by now, we
have to consider all views starting with the top-most one.
The port was succesfully tested a echo test and lighttpd. DHCP over
OpenVPN is not tested and probably will not work out of the box.
Therefore, the ip address etc. need to be specified manually.
For now, only ethernet bridging (using a TAP device) is supported.
Fixes#1235.
This commit adds a port the jitterentropy library to Genode. As
backend on x86_{32,64} 'rdtsc' is used and on ARMv{6,7} the
performance-counter.
Fixes#1239.
These file systems are provided on-demand by loading a shared library
when the fstab node is traversed. By convention this library is named
after the file system it provides. For example a file system that
provides a 'random' file system node is called 'vfs_random.lib.so'. It
is still possible to give the the node another name in the vfs. The
following code snippts illustrates this matter:
! [...]
! <config>
! <libc>
! <vfs>
! <dir name="dev"> <jitterentropy name="random"/> </dir>
! </vfs>
! </libc>
! </config>
! [...]
Here the jitterentropy file system, implemented in
'vfs_jitterentropy.lib.so' provides a file system node named 'random'
in the 'dev' directory. When traversing the vfs section the libc will
try to load 'vfs_jitterentropy.lib.so' but programs may access the
file system only via '/dev/random'.
Fixes#1240.
