This patch removes the support for executing subsystems of CLI monitor
within the GDB monitor. There are multiple reasons: First, the feature
remained unused for multiple years. Second, it relied on the base/elf.h
header to determine whether the started binary is dynamically or
statically linked. This header, however, is going to be removed from the
Genode API. Third, the feature will eventually break with the upcoming
changes of how components are bootstrapped. Finally, there is the plan
to turn CLI monitor into a sole front end of a dynamically configurable
init component. Once we pursue this plan, we'd need to reconsider the
GDB support anyway.
Issue #1832
In addition to now using the framework the playback is triggered by a
timer. For now it is a periodic timer that triggers every 11 ms which
is roughly the current Audio:out period (*).
The driver now also behaves like the other BSD Audio_out driver, i.e,
it always advances the play pointer. That is vital for the Audio_out
stack above the driver to work properly (e.g. the mixer).
(*) It stands to reason if it would be better to use the async ALSA
timer interface instead of using the Timer session.
Fixes#1892.
This driver uses the Usb session interface and provides a Block session
to its client. See _repos/os/src/drivers/usb_block/README' for more
information.
Fixes#1885.
Instead of only hardcoding "hw" read 'alsa_device' attribute from the
config node to determine the proper playback device. The default value
is still "hw" in case the attribute is not present.
Fixes#1884.
The driver might end up in an endless loop on systems that do not
contain an i8042 controller when probing the AUX interface. This
leads to busy looping and in the end to not annoucing the Input
service. Components that wait for the announcement of the service
will therefore hang as well.
Normally a service gets announced only if it is usable but in this
case this is inconvient because it renders all scenarios that use
the input_merger non working on x86 systems that only provide USB
input and do not have PS/2 at all.
Ideally, the PS/2 driver should only be started if the system needs it.
That is currently not feasible and for the time being we post-pone the
inevitable and back down after several unsucessful attempts to read
from the AUX interface while initializing the driver.
Fixes#1871.
The 'usb_report_filter' component takes the devices report from the
USB driver and generates a new devices report after checking each
entry against its device white-list. Before emitting the new report
it changes the configuration of the USB driver to contain the
required policy entries.
See 'repos/os/src/app/usb_report_filter/README' for more details.
Issue #1863.
Now, the right PCI bus:device:function (BDF) is reported to the kernel
during assign_pci syscall - beforehand it was ever 0:0.0. The BDF is
needed to lookup the correct DMAR unit the kernel has to configure. This
was revealed as the DMAR unit for Intel graphics on x201 is not the same
as for all other PCI devices we have drivers for on this platform.
Fixes#1848
Because a check for the TEST_WRITE configuration was missing as condition for a
packet submit, the test caused unwanted write access to the device.
Ref #1824
This patch adds diagnostic messages during the label-policy application,
if no policy for the session label was found or if the domain configured
in the policy node does not exist.
Instead of bailing out if the channel list is incorrect check config
node attributes and default settings first.
Being there also fix flawed LOG messages.
Fixes#1794.
* Provide paravirtualized block API for accessing the second partition
of the block device that is provided by the ESDHC driver.
* Provide paravirtualized serial API for sending log-output over Genodes
serial port.
* Use the latest Linux suggested in the USB Armory Wiki [1] when on USB Armory
while still using the older vendor Linux when on i.MX53 QSB. I.e.,
provide a device tree through RAM and a rootfs through the paravirtualized
block device when on USB Armory while providing ATAGs and Initrd when on
i.MX53 QSB.
* Switch on the LED on the USB Armory when the VMM catches a VM-exception
and switch it off again when as soon as the exception is handled. This
merely show-cases the ability to instrument the LED for such purposes. In an
ideal world, the LED is switched on as long as we're on the "Secure Side"
and switched off as long as we're not.

Move ADMA2 stuff to extra header and unit. Move ESDHCv2 implementations to
extra unit. Use exceptions instead of error codes. Clean-up documentation.
Ref #1497
The manual termination of multi-block writes via "Stop Transmission" commands
seems to leave the card in a busy state sometimes. This causes errors on
subsequent commands. Thus, we have to synchronize manually with the
card-internal state via "Send State" commands. Additionally, the method
for issuing the manual "Stop Transmission" commands was refined.
