Due to lacking hardware access the driver was test with one RTL8188EE
based device, namely [10ec:8179] (rev 01), only. As the access to the
PCI config space is restricted the driver loads the non power-saving
FW and the driver port is therefor only tested with that. The
accesses are documented should we choose to support them one way or
another later on.
The 'wifi.run' run script as well as Sculpt served as testing ground
where the driver worked fine so far.
Fixes#4714.
Check if we are able to submit the Usb packet before attempting to
allocate it. In case the queue is already full we wait until another
pending packet is freed.
Fixes#4701.
Up to now it was only checked if an issued admin command was processed
in a timely fashion. Otherwise it has been treated as failed.
However, the completion-queue entry was not examined and the caller was
not able to access the entry itself. Depending on the command, checking
the completion-queue entry might be necessary, e.g. GET/SET_FEATURE.

Since the 'Platform::Device' constructor will defer the creation until
the content of the devices ROM is valid performing the PRP list helper
creation afterwards should be done with valid IOMMU information.
Issue #4715.
Some USB devices (e.g., webcams) fail to deliver their configuration
descriptor early after power-up. Testing revealed that retrying the
requests usually succeeds on second or third attempt.
Fixes#4739
Genode build system allows to easily enable 'ccache' for builds. This
change allows to enable using 'ccache' also for build of reference
Linux kernel used during porting device drivers.
To enable 'ccache' it is enough to pass value of 'CC' variable when
executing Linux build but this build by default depends on time when it
is built which causes 'ccache' misses. To solve this issue additional
flags are passed to make build independent from time, current user and
host on which build is performed.
Issue #4718
With the new 'presets:' tag, .sculpt files can now refer to deploy
configurations to be integrated in the presets/ subdirectory of the
config file system. Those files can thereby be used as preconfigured
system scenarios. Such a preconfigured scenario can be loaded at
runtime by copying the preset file to config/deploy.
Issue #4731
In case of very rapid config ROM change (<300ms), the linux driver may still
be in progress of applying the previous change (e.g. switching connector on/off).
During this progress all tasks may become not runnable (waiting for IRQ/timeouts
until hardware state settles), the newest config ROM change/signal gets
dispatched, which lead to continuing the previous change request, but not
to re-starting/re-applying the new config change. To avoid this situation,
explicitly track whether a previous config change was finished and track if an
interim config change request came in. If so, re-start the lx_user
task with the newest config change.
Fixes#4721
The argument is superfluous because only run/image/uboot evaluated it
anyway, and the argument is always boot/image.elf. With this change, the
official semantics of run_image become: "replace the boot/image.elf file
by platform-specific file(s) at boot/ that can actually be booted".
Issue #4730
* Update links from forward rules only with forward rules and links from
transport-routing rules only with transport-routing rules. Besides raising
the performance of the code, this also fixes a former bug that allowed
forward-rule links to falsely stay active because of a transport-routing
rule that matched the client destination ip and port.
* Don't use good-case exceptions for updating TCP/UDP links on re-configuration
of the router.
* Make conditions when to dismiss a forward rule easier to read.
* Introduces != operator to the public Port class in the net library.
* Fix unnecessary log message that a link was dismissed when only a potentially
matching forward rule turned out to be not matching.
* Apply Genode coding style to if statements with a single body statement.
Fix#4728
This fixes a bug that was introduced by this earlier commit:
"nic_router: find forward rules w/o exceptions"
The NIC router used to falsely dissolve TCP/UDP connection states when
reconfiguring although the connection states were still legal according to the
new config. The reason was that the above mention commit nested lambdas but
missed to return from the last nesting level when having found a configuration
that legitimates the connection state.

The semantic of .NOPARALLEL has changed in GNU Make 4.4
Quote:
New feature: .NOTPARALLEL accepts prerequisites If the .NOTPARALLEL
special target has prerequisites then all prerequisites of those targets
will be run serially (as if .WAIT was specified between each
prerequisite).
This means that only prerequisites are made sequential. Before
everything within a Makefile would be done in sequential order.
Therefore, we had to add the *.hash target (appears multiple times) to
the .NOPARALLEL prerequisites.
issue #4725
Tests on qemu would fail when started with RAM sizes from 1025MiB to
2048MiB, because the the mapping hole in the page table from 1GiB to
2GiB would interfere with qemu's mapping addresses for ACPI.
Identity-map the complete first 4GiB of memory to catch all early
memory accesses during bootstrap.
Fixes#4724.
This patch simplifies the 'Deploy::update_managed_deploy_config'
interface by keeping an internal copy of the currently used deploy
template inside the 'Deploy' class. The template is updated whenever
the config/deploy file is modified.
This change weakens the coupling between the '_manual_deploy_rom' and
the '_deploy' subsystem, easing the upcoming implementation of the
switching between presets.
Adds befriended test-local wrappers for the classes Cpu_share and Cpu_scheduler
and adds a print method to the scheduler wrapper that prints the internal state
of the scheduler to the given output. Cpu_shares are referenced in the output
via a the IDs that the test uses to organize them. I.e., this corresponds to
how the CPU shares are named when calling the atomic steps the test is made of.
