Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.
Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.
Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.
Issue #3101
This patch unconditionally applies the labeling of sessions and thereby
removes the most common use case of 'Child_policy::filter_session_args'.
Furthermore, the patch removes an ambiguity of the session labels of
sessions created by the parent of behalf of its child, e.g., the PD
session created as part of 'Child' now has the label "<child-name>"
whereas an unlabeled PD-session request originating from the child
has the label "<child-name> -> ". This way, the routing-policy of
'Child_policy::resolve_session_request' can differentiate both cases.
As a consequence, the stricter labeling must now be considered wherever
a precise label was specified as a key for a session route or a server-
side policy selection. The simplest way to adapt those cases is to use a
'label_prefix' instead of the 'label' attribute. Alternatively, the
'label' attribute may used by appending " -> " (note the whitespace).
Fixes#2171
Instead of providing a buffer to the client and blitting from that
to the "real" framebuffer as an option, with this commit we always do so.
Thereby its possible to immediately destroy the old framebuffer used by
hardware when a configuration change is done, and a new framebuffer
is used. This also simplifies the modesetting.
Moreover, this commit fixes an issue when not using the connector reporting.
Until now the initial mode detection of connectors was only done when
the report was created. this is a regression that entered the driver
when upgrading to the recent Linux kernel version.
Ref #1997
* enable i915 driver from Linux 3.14.5
* tested for generation 5 till 8 GPUs
The driver can be configured at run-time via the config ROM. Every
connector of the graphic card can be configured separately using the
following syntax
<config>
<connector name="LVDS-11" width="1280" height="800" enabled="true"/>
</config>
Also, when enabled within the intel framebuffer driver configuration like
the following
<config buffered="yes"/>
a simple ram dataspace is propagated to the client and the driver
itselfs copies from that buffer to the framebuffer triggered via refresh
calls. This option is useful to alleviate tearing effects.
The driver distributes all available connectors of the graphic card and
their supported resolutions via a report. It looks like follows
<connectors>
<connector name="LVDS-11" connected="1">
<mode width="1280" height="800" hz="60"/>
...
</connector>
...
</connectors>
The driver distributes the report only if this is stated within its
configuration, like the following
<config>
<report connectors="yes"/>
</config>
