The platform-specific get_msi_params function returns MSI parameters for
a device identified by PCI config space address. The function returns
false if either the platform or the device does not support MSI mode of
operation.
Extend the base-hw Irq_session_component class with _is_msi, _address
and _value variables required to support MSI mode of operation.
Return MSI configuration in info() function if _is_msi is set to true.
Enable the ACPI functionality in the platform_drv on hw_x86_64_muen and
provide a simple generated XML report as ROM session in order to make
the PCI configuration space available.
This is a requirement to implement support for MSI on hw_x86_64_muen.
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.
For some reason 'os/config.h' is imported through 'launchpad.h', when linking an
undefined symbol ('Genode::config') is produced, which actually should not
happen.
This commit adds rocket core on the Zynq FPGA support to base HW. It also takes
advantage of the new timer infrastructure introduced with the privileged 1.8 and
adds improved TLB flush support.
fixes#1880
The wrapper functions (e.g., 'Unwind_*' and friends) now have the same signature
as the original function in 'libgcc', reside in a separate C file which is
archived to cxx.lib.a. In supc++.o we prefix the wrapped functions with '_cxx_'.
This also enables support for riscv.

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.
This patch removes a superfluous resize request at the creation time of
a new window, which resulted from _requested_size being initialized with
zero whereas the _geometry was initialized with the actual window
geometry. In some cases, this inconsistency led to the report of a new
resize request for the size 0x0, which is obviously wrong. I.e., it
leads clients to believe that the user has closed the window.
This patch resets the part of the window state that is responsible the
dragging of window controls once the drag operation is finalized.
Without it, the window was wrongly positioned when leaving the maximized
state after a previous resize operation.
This patch adds support for manipulating the window layout with keyboard
actions. It supports the toggling of fullscreen (aka maximize), the
raising of the currently focused window, and the focusing the next/previous
window.
This patch adds the mechanics for detecting key sequences to the window
layouter. Sequences for layouter actions can be expressed in the
layouter configuration. They cannot trigger any real action yet.
This patch weakens the themed decorator's demands with respect to the
supplied theme data. It no longer strictly requires the specification of
the '<closer>', '<title>', and '<maximizer>' nodes and the accompanied
png/tff data. Furthermore, the default.png can be left out if both decor
and aura have a size of zero.
This patch enhances the layouter to apply a label-dependent policy
for the placement of new windows. The policy may contain the
attributes 'xpos', 'ypos', and 'maximized'. If the latter is set
to "yes", the matching window will appear in maximized state.
This patch ensures that we never request a zero-sized virtual
framebuffer from nitpicker even when instantiating the object with zero
width or height. It therebu removes the burden of handling the resulting
invalid framebuffer dataspace from the user of the Nitpicker_buffer
utility.
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.
Interfaces that have been claimed by a component always have to be
released when the session is closed in case the component
malfunctioned.
