The argument was originally designated to restrict the reach of the
trace monitor but the idea remained unimplemented. It is now superseded
by the use of the trace-session label as trace-subject filter.
Issue #847
This patch changes core's TRACE service to expose trace subjects only if
their PD label matches the label of the TRACE monitor. Hence, by default,
a trace monitor can only observe itself and its child components. Only
if the trace monitor's parent rewrites the trace-session's label, the
view of trace monitor can become broader. For example, when rewriting
the trace label to an empty string "", the trace monitor becomes able to
observe the sibling components hosted in the same init instance as the
trace monitor.
To grant a trace session the special privilege of obtaining a global
system view (including the kernel's trace subjects), the top-level init
has to rewrite the session's label to an empty string. At core, this
specific label "init -> " is handled as a special case that discharges
the filtering/namespacing of trace subjects.
Note that the trace-subject label as reported as subject info is now
given relative to the label of the trace session. As a nice side effect
of this change, the pkg/test-trace_logger works now when executed by the
depot_autopilot as well as via the test.run script.
Issue #847
This option is useful in cases where batching is configured and
failing to fetch a resource should not influence the over-all
result.

In the scope of alloc_dma_buffer(), Out_of_* exceptions might be thrown
at different stages. By adding a Guard object, we make sure to rollback
already created objects accordingly.

As a consequence of the adding IOMMU support to the platform driver,
additional RAM and CAPs are needed for setting up IO page-table
structures.
genodelabs/genode#5002
The platform driver needs additional 2MB of RAM for managing IO page
tables (root table and context tables) that are shared among sessions.
genodelabs/genode#5002
By adding the `irq_type` argument, one can explicitly specify whether to
use LEGACY, MSI or MSI-X interrupts. We formerly used the
`device_phys_config` to implicitly select MSI, however, with the
addition of IOMMU support to the platform driver there is at least one
instance where we need an MSI for a non-PCI device.
Yet, by adding another session argument to the Irq session, we exceed
the character limit for session args. Since not all arguments are
relevant for LEGACY interrupts resp. MSI, we can split the Irq_connection
constructor to handle the two cases separately and omit unneeded
arguments.
genodelabs/genode#5002
DMA buffer allocations are always performed as full pages. However, they
got mapped into the IOMMU domain using the requested size, which may not
be a multiple of the page size. This behaviour was introduced as a regression
by #4761 and is corrected by this commit.

The virtual add_range()-method must not be called from the base-class
constructor since the derived class is not be fully initialized at
this point.

The sculpt manager views only launchers in the + menu that are not present in
the runtime already. However, this check was missing when finding the right
launcher on a click event inside that menu. This could cause the manager to
try deploying an already deployed launcher a again (without any effect)
instead of deploying the launcher that was actually clicked.
Ref #5064
This is a follow-up commit to the adaptation of the run scripts to the
consistent use of [build_artifacts] (issue #4860).
The missing build of libm remained undetected until the recent removal
of implicit shared-library builds (issue #5061).
This patch removes the implicit build of all shared libraries a target
depends on. Targets only depend on the respective ABIs instead. This
alleviates the need to locally build complex shared libraries (think of
Qt) when developing applications. Instead, application developers can
use binary depot archives.
The implementation splits the mk/lib.mk file into three files:
- mk/a.mk for building one static library (.lib.a)
- mk/so.mk for building one shared object (.lib.so)
- mk/abi.mk for building one ABI stub (.abi.so)
Furthermore, the commit moves messages and the collection of build
artifacts to var/libdeps, triggers the build of kernel-specific
ld-<kernel>.lib.so, and prunes the lib-dependency tree at ABIs.
Fixes#5061
- finished tx ack queue should be checked before new allocations
- packets which got not sent must be released in packet stream,
otherwise the network packet stream gets filled up and starves after a while
- rRegister for ack avail packets and process them concurrently to EMT-* threads
by nic_ep thread (thanks @Peter for the findings) + add synchronization.
- add sigh_ready_to_submit to network adapter to improve latency by notifying
the network model explicitly in case we had a full packet stream error case
(_retry resp. VERR_TRY_LATER)
Fixes#5045
