852bc3fc62 base-linux: remove exceptions from region_map_mmap
This patch replaces the exception-based error propagation by the use of
'Attempt' return values, which eliminates side effects of the exception
handling - cxx_heap allocations - from code paths that are used by the
the cxx_heap itself (when growing the cxx_heap).

It thereby fixes the failure of the sub_rm test at the "attach RAM ds to
any position at sub rm - this should fail" step.

75bfc37b18 sculpt: screensaver infrastructure
This patch enhances Sculpt with the ability to detect user inactivity
for driving a screensaver by combining nitpicker's hover and focus
reports with a timer.

8463f4910a nitpicker: improve activity reporting
Nitpicker's hover and focus reports contain an 'active' attribute, which
can be inspected for the detection of user activity, e.g., as trigger
for a screensaver or for dynamic clipboard policies.

When using the 'Event' session, the reporting code updated the reports
only on incoming events. This patch adds the periodic reporting as used
when using the old 'Input' session.

1cac134030 lx_kit: support multiple pending IRQs
Decoupling the scheduler execution can lead to missed interrupts
because the current implementation only handles one pending
interrupt and requires immediate processing.

This commit introduces a helper object that is used to capture
any occuring interrupts that are then handled consecutively.

caac994da8 lx_kit: decouple schedule execution
Prior to this commit, whenever an external event occurred, for example
timer or interrupt, the corresponding I/O signal handler was triggered.
This handler unblocked the task waiting for the event and initiated the
immediate execution of all unblocked tasks. Since these tasks may hit
serialization points, e.g. synchronously waiting for packet stream
operations, that require handling of other I/O signals this leads to
nested execution. This, however, is not supported and mixes application
and I/O level signal handling.

The flagging of the scheduling intent is now decoupled from its
execution by using an application level signal handler that is run in
the context of the components main entrypoint. The I/O signal handler
now triggers the scheduling execution by sending a local signal to
the EP.

Since it might be necessary to execute a pending schedule from the EP
directly the scheduler is extended with the 'execute' member function
that performs the check that the scheduler is called from within the
EP and triggers the execution afterwards.

1f1fafb0cf intel_fb: disable encoders of disconnected ports
On disconnect of displays, e.g. seen with Type-C connectors, the encoder was
not properly disabled due to a missing drm_client_modeset_commit. In order that
the commit succeed, however a fb must be assigned to the modeset. Missing to
do so leads to an -EINVAL by the drm_client_modeset_commit.

7b7851abfb vfs/tresor_trust_anchor: fix alignment faults
Fixes alignment faults that occured in the AES256 implementations while
wrapping or unwrapping keys on imx53_qsb, imx6q_sabrelite, and imx7d_sabre.
The problem was that the unwrap_key/wrap_key functions did reinterpret casts
from unsigned char pointers to uint64_t pointers and then directly used the 64
bit values of referenced by the latter. Most probably this caused the compiler
to optimize operations in the assumption that the pointer is 8-byte aligned
which then created alignment faults.

As a solution, this commit changes the interface of the wrap_key/unwrap_key
functions to take uint64 pointers as arguments instead of unsigned char
pointers and then adapts the function users to ensure that they refer to
appropriately aligned memory regions.

317c5429d2 dde_bsd: decrease overall memory consumption
The initial memory backend implementation was brought over from DDE
Linux and was geared towards use-cases where a high-performing
allocator is useful. In case of the audio driver this is overkill
and since no other driver that could benefit from such an
implementation was ported in the meantime rather use a simpler
implementation that keeps the overhead down.

1fd1786122 test/lx_hybrid: don't call glibc exit
This patch removes the use of the Entrypoint::schedule_suspend mechanism
and the call of glibc's exit from the lx_hybrid tests, for two reasons.

First, the interplay of atexit handlers executed by the glibc and
Genode's lx_hybrid library is complicated while bringing no benefits in
practice as lx_hybrid applications are usually servers that don't exit
anyway.

Second, the Entrypoint::schedule_suspend mechanism in not used by any
other component. By removing its use from the lx_hybrid tests, we can
remove this mechanism from the base library.

afaabb3121 pc_nic_drv: add R8169 driver
This commits enables the R8169 driver and was tested with two
RTL8168h/8111h (10ec:8168 rev 0x15 sub 1462:7a38 / 1d05:109f) and
two equal RTL8125B (10ec:8125 rev 0x5 sub 1458:e000) devices
running Sculpt.

Firmware loading is for now not implemented but specific Linux
commits suggest it could be necessary. However, doing so will be
post-poned until we have gathered more experience with the driver.

Restarting the driver might lead to the following IOMMU error
messages but the device seems to work anyway:
