The implementation conflicted with the implicit declaration of bzero:
.../repos/dde_bsd/src/lib/audio/mem.cc: In function ‘void bzero(void*, size_t)’:
.../repos/dde_bsd/src/lib/audio/mem.cc:377:2: warning: ‘nonnull’ argument ‘b’ compared to NULL [-Wnonnull-compare]
For historical reason the 'strlcpy' implemention was directly pull in
into the emulation environment. There is, however, no reason not to
use the contrib sources in the usual fashion.
Issue #3929.
The supported drivers so far exclusively used PCI and for practical
reasons the emulation environment was to tied to. To make future
addition of drivers that employ other transport busses easier, split
the bus handling into its own backend.
This is preliminary clean-up work before introducing the USB audio
driver.
Issue #3929.
Besides updating to a newer version the update adds the AC97 ICH driver
and addresses shortcomings with the OpenBSD emulation environment:
* Fix 'delay(9)' implementation - it now properly uses 'us' as unit,
which results on faster initialization of the drivers.
* Fix LOG output that got lost during commit f23579532 and bring over
the printf implementation from dde_linux for more structured
printing.
* As said the driver now recognizes the AUICH devices. So far it was
only tested with the device model in VirtualBox where it produces
stuttering audio, investigating the cause is still ongoing.
Fixes#3641.
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
A binary file may be a temporary Vim .swp file when examining contrib
sources. The commit prevents build errors like
.../repos/dde_linux/lib/mk/lxip_include.mk:29:
target '.../x86_64/var/libcache/lxip_include/include/include/include/Binary'
given more than once in the same rule
.../repos/dde_linux/lib/mk/lxip_include.mk:29:
target '.../x86_64/var/libcache/lxip_include/include/include/include/file'
given more than once in the same rule
...
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.
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
These audio drivers enable support for Intel HD Audio (Azalia) and
Ensoniq AudioPCI (ES1370) compatible soundcards. They are ported
from OpenBSD 5.7.
Fixes#1498.
