Due to what seems like a copy-and-paste error, the wrong union member
was used to compare the label. Fortunately, as both structs have the
same memory layout that did not result in any issue.
Issue #3929.
Originally, the kernel code should have been executed within the
context of the main task like it is done in dde_linux. The initial
port of the HDA driver, however, did not required doing so and the
session called code directly.
When using USB device, that is no longer possible as we have to
suspend the execution during the execution of the kernel code. So
we pass in the audio data and schedule the kernel.
Fixes#3929.
This becomes necessary in case of the USB audio driver where we have
to wait for and query the function first.
That being said, alternatively we could also announce the session but
ignore any request until there is a device we can use.
Issue #3929.
With this commit the timer back-end uses the timeout framework to
schedule any occuring timeouts and for providing the current time.
For now there is only one timeout, the unsolicited azlia codec event
and therefore the timeout queue consists of solely one timeout object.
In addition a timer session is used for implementing 'delay()' where
we have to block until the delay is completed.
Issue #3929.
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.
Instead of the generic name, call the PCI driver 'pci_audio_drv'.
This is preliminary clean-up work before introducing the USB audio
driver.
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.
* Updating the run script was missed in commit "dde_bsd: remove
configration attributes".
* Decrease output and input volume to "more sane" levels.
Issue #3929.
The driver always opens the audio device in duplex mode, i.e.,
playback and recording. Setting the 'playback' or 'recording' attribute
only influnces the service announcement. Due to changes made in a more
recent OpenBSD release recording must be set enabled explicitly anyway.
Since we already provide the interface that mirrors the one used by
OpenBSD 1:1 in the configuration use that and the remove the additional
config attributes.
Fixes#3757.
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 enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.
Fixes#3208
Since QEMU might put the audio device at 00:03.0, also check if the
vendor is Intel. Hopefully we do not render HDA on real machines
useless with this changes (so far I have not encountered one).
Fixes#3263.
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
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
