Consumes the information about reserved memory region reports from
the devices ROM, and adds appropriated mappings to the corresponding
device PD.
Ref genodelabs/genode#4578
We need the information about reserved memory region reports
from the ACPI tables within the platform driver to pre-fill
IOMMU tables with the corresponding mappings. Therefore,
the pci_decode component now parses the information from the
ACPI ROM, and adds "reserved_memory" nodes to all related
devices in the devices report.

In case of the GPU multiplexer, we need to delegate MMIO memory
to the framebuffer client in form of a managed dataspace. To be
able to attach a given Platform::Device::Mmio object to a region map
we need to access its capability.

This commit fixes two issues with the timeout lib and the base-hw src recipe:
* Add source files of timeout lib to recipe content.
The files weren't copied to the depot until now. However, the archive
nonetheless built successfully because of the second issue that is described
below.
* Get rid of the usage of the BASE_DIR variable in the timeout lib.
The BASE_DIR variable always resolves to the repos/base directory even when
building in a depot. That said, the use of BASE_DIR in make-files that are
not part of the build system itself must be avoided. Instead, REP_DIR,
REP_INC_DIR, and $(call select_from_repositories, ...) should be used.

This commit gets rid of the router-local wrapper of Genode's AVL string tree
and replaces it with Genode's new Dictionary structure. The Dictionary is now
used for managing domains and NIC clients. Due to this change, the formerly
necessary helper classes Domain_base and Nic_client_base could be removed as
well.

When creating an Irq connection to a component (not core), e.g. a pin
driver, we typically need a to provide a session label in order to apply
a session policy and to distinguish multiple sessions from the same
component.

This is a follow-up commit for "menu_view: configurable alpha channel
and bg color", which simplifies the code. The '_no_alpha' surface is not
needed because the 'Gui_buffer' provides a 0x0 alpha surface when using
the opaque mode.
The default file-system communication-buffer size of 128 KiB combined
with the clamping of requests to 1/4th the buffer size results in the
fragementation of read operations into 32 KiB chunks. This is overly
conservative and causes high context-switch overhead down the storage
stack (vfs server -> part_block -> block driver).

With the increase of MAXPHYS, the rump kernel requests a contiguous
allocation of 2101248 bytes, which exceeds the allocator's block size of
2 MiB.
Error: backend allocator: Unable to allocate memory (size: 2101248 align: 12)
The patch avoids this corner case by increasing the allocator's block
size to 4 MiB.

The NIC router README claims that the 'dns_config_from' attribute in a DHCP
server configuration binds the propagated link state of all interfaces at the
domain of the server to the validity of the IP config of the domain that is
given through 'dns_config_from'.
However, this was not true. The router missed to implement this detail which
led to clients of such a DHCP server sending DHCP DISCOVER packets too early.
These early DHCP DISCOVER packets were dropped by the router potentially
causing a big delay until the client started a new attempt. Unnecessary long
network boot-up delays were observed with at least the lwip run script and
Sculpt on the PinePhone and could be tracked down to this former
inconsistency in the router.
This commit fixes the inconsistency.

This patch changes the access of pkg-archives files such that the file
read only once per pkg, not for each ROM module used by the package.
Issue #4611
By caching directory listings, the performance of depot_query is no
longer impeded by a massive amount of stat calls while searching for ROM
module locations.
Issue #4611
Upon closer inspection of real-world access patterns, it turns out that
the 'Stat_cache' and 'Cached_rom_query' are not as effective as hoped
for because cache hits are rare while querying pkg blueprints.
However, by increasing the initial size of the blueprint reporter from 4
KiB (default) to 64 KiB has a great effect. With the small default
report size, the querying of blueprints is repeated until the buffer
size suffices, incrementing the buffer size by 4 KiB in each iteration.
Issue #4611
The new 'Dictionary' provides an easy way to access objects using
strings as key. The 'String' received the 'operator >' to simplify the
organization of strings in an AVL tree.
The patch removes the former definition of the 'operator >' from the
platform driver because it would be ambigious now.
Fixes#4610
This patch avoids repetitive depot queries at the start of the Sculpt
system.
We don't need to trigger a query unconditionally whenever the
managed/deploy changes because the call of 'handle_deploy' triggers a
query when needed.
We don't need to trigger a query once the prepare step is completed
because the depot_query component is spawned at this point. The initial
blueprint produced by the depot_query component, in turn, triggers the
'handle_deploy' mechanics in the sculpt manager.
The constructor of the Sculpt manager's 'Main' does not need to call
'depot_deploy' because the prepare step - which is a precondition for
the deployment - cannot be completed at this point anyway.
Do not advance ring buffer positions when playing silence, additionally
to not send progress signals when playing silence. Silence implies
underrun in the client side - not progress.
issue #4609
In case a driver is waiting for data, is should only investigate 'pos'.
It should not advance the ring in any way until there is data available.
issue #4609
This patch consolidates the repetitive error handling across the RPC
functions, which take node handles or directory handles as arguments.
During this change, I noticed that directory handles - which are values
provided by the client - were not checked for their type before being
used. A misbehaving client may open a file, manually construct a
directory handle using the number of the file handle, and invoke a
directory operation at lx_fs, which would then wrongly access a file
node as directory node.
This patch solves this issue by introducing two distinct methods
_with_open_node and _with_open_dir_node, which perform the respective
safety checks.
Fixes#4608
