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.
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.
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.
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
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.
This patch fixes a potential race condition that could happen if a
client connects to nitpicker before the signal for the import of the
initial configuration was delivered. In this case, nitpicker would be
unable to assign a domain to the session (because this information comes
from the configuration), rendering subsequent calls to 'mode' invalid.
The patch solves this problem by manually calling the signal handler
for importing the configuration.
This patch reimplements the nit_fb server using the server API and
thereby enables the dynamic resizing the of the framebuffer.
Note that the new implementation does not feature the ability to perform
a periodic refresh via the 'refresh_rate' configuration argument. This
feature was removed because the refresh policy can (and should) always
be implemented on the client side.
This patch adds support for the consecutive re-dimensioning the virtual
framebuffer. When changing the buffer size, the session gets upgraded by
the missing portion of the quota instead of donating the whole size of
the new buffer each time.
