Several nightly network-related tests fail currently on sel4/pc because the
new e1000 NIC driver requires more capabilities. The "drivers nic" package
was already adapted to the new requirement but some tests fail to provide
enough caps to the corresponding sub system. This commit tries to fix all
remaining tests.
Ref #4923
* Adds a new component server/nic_uplink that forwards packets unmodified
between one Uplink session at one side and potentially multiple Nic sessions
at the other side.
* Adds a new run script nic_uplink.run that does a basic test with multiple
Nic clients on this component and adds it to the autopilot list.
* Adds a new depot recipe src/nic_uplink for this component.
* Adds a new depot recipe pkg/pc_nic for deploying the pc_nic_driver together
with a nic_uplink server. This allows for raw access to the network connected
to the Nic of the system in contrast to the commonly used routed and NAT'd
access via NIC router. That said, it enables the use of network protocols
not yet supported by the NIC router at the cost of less protection.

by just test the migration feature, without relying on load measured on the
CPUs. On Qemu (and depending on other load in the Linux system), the migration
feature gets not triggered in time reliable.
* add a sensible priority setup into the test script in order to protect
drivers and stack components from the demanding net clients
* delay the starting of the net clients by 5 seconds in order to give the
drivers and stack components some time to startup in peace
* use only explicit service routing and caps values

While this approach still scans "holes" in the bus range, it stops
scanning at the maximum subordinate bus number reachable from the base
PCI bus at the host bridge. Startup under Qemu no longer takes about 12
seconds for scanning 256 buses.
On some platforms (x86_32/pistachio, x86_64/sel4) system startup is slow
and the previously configured 30 seconds not sufficient. With this commit, the
timeout is raised to 60 seconds only when running on such a platform.

This test was originally a copy of ping.run and therefore unnecessarily
inherited all its complexity for testing ping component behavior. Additionally,
ping.run was more actively maintained and evolved over time whereas
nic_dump.run didn't receive the same care. Now, the test fails on certain
platforms although NIC dump works just fine. Therefore, this commit reduces the
test behavior to what is really necessary for testing nic_dump and by doing so,
also fixes the failing targets.
Fixes#4926
On x86_32 okl4, the test timed out although the test timeout was already at
240 seconds for this platform. Instaed of raising it further, this commit
reduces the number of ping rounds for all platforms that are considered as
slower by the test.
Ref #4923
The new monitor component at os/src/monitor is the designated successor
of the gdb_monitor. This initial version, however, implements only the
subset needed to inspect the memory of the monitored component(s).
In contrast to the gdb_monitor, the new component supports the monitoring
of multiple components, leveraging the sandbox API. It can therefore be
used as a drop-in replacement for the init component. Like the gdb_monitor,
the new monitor speaks the GDB protocol over Genode's terminal session.
But the protocol implementation does not re-use any gdbserver code,
sidestepping the complexities of POSIX.
There exist two run scripts illustrating the new component. The
os/run/monitor.run script exercises memory inspection via the 'm' command
by letting a test program monitor itself. The os/run/monitor_gdb.run
script allows for the interactive use of GDB to interact with monitored
components.
Issue #4917
"-cpu phenom" does not support all CPU instructions necessary with
gcc 12 toolchain update issuing more SSSE3, e.g. pshufb.
Additionally, remove good/bad Qemu version check of outdated versions.
Issue genodelabs/genode-world#329
Since repos/base/board/pc/devices is empty, the run script no longer
works on PC. Nobody noticed because the use case of this run script -
as development test loop for the ps2 and fb_sdl - are better served by
other scenarios nowadays, e.g., using declaring 'build: ps2' for a
custom Sculpt OS build.
Removed in the context of issue #4860.
This commit introduces support for the HMB feature and will setup the
buffer during start-up. The host-memory-buffer (HMB) feature is mostly
used on NVMe devices that do not make use of an DRAM cache to store its
translation tables amongst other operational data. Not using HMB can
impair the performance on such devices.
The memory is allocated in 2 MiB chunks of DMA-capable memory and its
total size in bytes is configurable via the 'hmb_size' config attribute.
The driver always checks the minimal and preferred size of the HMB and
issues a warning in case it is not enabled via the configuration.
Moreover, if the configured size is less than the minimal amount
required by the device the HMB is not configured at all and a warning
is issued also. If the configured size is more than the preferred size
it will be capped to that amount.
Fixes#4715.
This commit enables users of the VMM to define CPU type and count, RAM size,
kernel and initrd ROM names, GIC version, and Virtio devices to be used.
Derived from the configuration values a flattened device-tree blob (DTB) is
generated and transfered to the VM.

Implement the guest code in dedicated assembler source file, assemble
and link the binary to vmm_x86. The resulting guest-code binary
populates one page that is mapped to host the reset vector of the guest.
This approach simplifies future guest code adaption resp. extension,
e.g., to test rdmsr/wrmsr exiting.
Fixes#4638
