Also remove 'requires_installation_of', while also checking sbin
directories in 'have_installed'. The run scripts have been adjusted
accordingly.
Fixes#2853
This is a follow-up commit to "Increase default warning level", which
overrides Genode's new default warning level for targets contained in
higher-level repositories. By explicitly whitelisting all those targets,
we can selectively adjust them to the new strictness over time - by
looking out for 'CC_CXX_WARN_STRICT' in the target description files.
Issue #465
This patch reduces the number of exception types by facilitating
globally defined exceptions for common usage patterns shared by most
services. In particular, RPC functions that demand a session-resource
upgrade not longer reflect this condition via a session-specific
exception but via the 'Out_of_ram' or 'Out_of_caps' types.
Furthermore, the 'Parent::Service_denied', 'Parent::Unavailable',
'Root::Invalid_args', 'Root::Unavailable', 'Service::Invalid_args',
'Service::Unavailable', and 'Local_service::Factory::Denied' types have
been replaced by the single 'Service_denied' exception type defined in
'session/session.h'.
This consolidation eases the error handling (there are fewer exceptions
to handle), alleviates the need to convert exceptions along the
session-creation call chain, and avoids possible aliasing problems
(catching the wrong type with the same name but living in a different
scope).
This patch replaces the 'Parent::Quota_exceeded',
'Service::Quota_exceeded', and 'Root::Quota_exceeded' exceptions
by the single 'Insufficient_ram_quota' exception type.
Furthermore, the 'Parent' interface distinguished now between
'Out_of_ram' (the child's RAM is exhausted) from
'Insufficient_ram_quota' (the child's RAM donation does not suffice to
establish the session).
This eliminates ambiguities and removes the need to convert exception
types along the path of the session creation.
Issue #2398
Ldso now does not automatically execute static constructors of the
binary and shared libraries the binary depends on. If static
construction is required (e.g., if a shared library with constructor is
used or a compilation unit contains global statics) the component needs
to execute the constructors explicitly in Component::construct() via
Genode::Env::exec_static_constructors().
In the case of libc components this is done by the libc startup code
(i.e., the Component::construct() implementation in the libc).
The loading of shared objects at runtime is not affected by this change
and constructors of those objects are executed immediately.
Fixes#2332
A binary file may be a temporary Vim .swp file when examining contrib
sources. The commit prevents build errors like

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
Replace 'attribute(...).has_value("yes")`
with 'attribute_value(..., false)'.
This allows for boolean configuration to be set with values such as
"true", "false", "yes", "no", or "1", "0".
Fixes#2002
In addition to updating the contrib sources the driver now uses the
new Component API and will report the internal mixer state.
Reporting of the mixer state is enabled by adding the 'report_mixer'
attribute to the drivers configuration and setting its value to 'yes'.
The following snippets illustrates the format of the report:
!<mixer_state>
! <mixer field="inputs.beep" value="108"/>
! <mixer field="outputs.hp_sense" value="plugged"/>
! <mixer field="outputs.master" value="128,128"/>
! <mixer field="outputs.mic_sense" value="unplugged"/>
! <mixer field="outputs.spkr_muters" value="hp,mic"/>
!</mixer_state>
The mixer state may expose other mixer fields as well, depending on the
used sound card. The naming scheme of the attributes intentionally
matches the naming scheme of OpenBSD's mixerctl(1) program.
Each 'mixer' node can be used to configure the audio driver by using it
in its configuration, e.g.:
!<config report_mixer="yes">
! <mixer field="outputs.master" value="255,255"/>
!</config>
This configuration will set the output volume to the highest possible
value. Although it is now also possible to update the configuration
at run-time it should not be done while the driver is currently playing
or recording because it may provoke the generation of artefacts.
Fixes#1973.
This patch cleans up the thread API and comes with the following
noteworthy changes:
- Introduced Cpu_session::Weight type that replaces a formerly used
plain integer value to prevent the accidental mix-up of
arguments.
- The enum definition of Cpu_session::DEFAULT_WEIGHT moved to
Cpu_session::Weight::DEFAULT_WEIGHT
- New Thread constructor that takes a 'Env &' as first argument.
The original constructors are now marked as deprecated. For the
common use case where the default 'Weight' and 'Affinity' are
used, a shortcut is provided. In the long term, those two
constructors should be the only ones to remain.
- The former 'Thread<>' class template has been renamed to
'Thread_deprecated'.
- The former 'Thread_base' class is now called 'Thread'.
- The new 'name()' accessor returns the thread's name as 'Name'
object as centrally defined via 'Cpu_session::Name'. It is meant to
replace the old-fashioned 'name' method that takes a buffer and size
as arguments.
- Adaptation of the thread test to the new API
Issue #1954
This patch integrates three region maps into each PD session to
reduce the session overhead and to simplify the PD creation procedure.
Please refer to the issue cited below for an elaborative discussion.
Note the API change:
With this patch, the semantics of core's RM service have changed. Now,
the service is merely a tool for creating and destroying managed
dataspaces, which are rarely needed. Regular components no longer need a
RM session. For this reason, the corresponding argument for the
'Process' and 'Child' constructors has been removed.
The former interface of the 'Rm_session' is not named 'Region_map'. As a
minor refinement, the 'Fault_type' enum values are now part of the
'Region_map::State' struct.
Issue #1938
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
Fix#1673
Instead of looping the whole queue, the driver now loops on the first
invalid packet. In any case it will send a progress signal to its
client.
Fixes#1666.
With the introducation of the Audio_in session interface it makes
sense to rename the current available audio drivers. At the moment
only the dde_bsd audio_drv supports Audio_out as well as Audio_in.
The Linux audio_drv only supports Audio_out (there is no demand for
Audio_in support currently) but is renamed nonetheless to make it
easiert to write generic run scripts.
Issue #1644.
The driver is now able to record audio samples. In contrast
to playback it has to be enabled explicitly by setting the
configuration attribute 'recording' to 'yes'. Playback is by
default enabled but may be disabled by setting 'playback' to
'no'. Furthermore it is now possible to configure the mixer
from the configuration. For now, the interface used by vanilla
OpenBSD is just exported.
The following snippet shows how to enable and configure recording
on an Thinkpad X220 where the headset rather than the internal
mic is used as recording source:
! <start name="audio_out_drv">
! <resource name="RAM" quantum="8M"/>
! <provides>
! <service name="Audio_out"/>
! <service name="Audio_in"/>
! </provides>
! <config recording="yes">
! <mixer field="outputs.master" value="255"/>
! <mixer field="record.adc-0:1_source" value="sel2"/>
! <mixer field="record.adc-0:1" value="255"/>
! </config>
! </start>
In addition to selecting the recording source the playback as
well as the recording volume are set to 255 (maximum).
Information about the available mixers and settings in general
may be obtained by setting the 'verbose' to 'yes' in the config
node.
Issue #1644.
Unfortunatly, there is no support for any HDMI/DP based HDA codecs in
this driver. Therefore we try to filter out known devices (normally the
PCI device on 00:03.00). This could also be done in the platform_drv's
configuration by explicitly naming the BDF but for better or worse that
will not work when using a wildcard class like HDAUDIO which is done in
generic run scripts.
Issue #1644.
These audio drivers enable support for Intel HD Audio (Azalia) and
Ensoniq AudioPCI (ES1370) compatible soundcards. They are ported
from OpenBSD 5.7.
