When working with GPIO interrupts on i.MX6SX for Ethernet PHYs
it became obvious that the GPIO driver repeatedly receives interrupts
for the same event, because it acknowledges the interrupt before a
client has handled the event.
Ref #2750
In other words: Loosen the former property that suspend can only be
called from the first user stack and, thus, enable additional user
stacks, e.g., in coroutine libraries.
Fix#2737
This driver component provides support for using consumer NVMe storage
devices, i.e. it omits name space managment and will always use the
first name space, on Genode. For now it defaults to a reasonable low
configuration:
- 1 I/O queue (completion/submission tuple)
- 128 entries in the I/O queue
- 4096 as the only I/O transaction memory page size
Fixes#2747.
The 'default' attribute is useful to change the default value for those
protocol attributes that are not explicitely set in the configuration of
the component.
Issue #2738
Each supported protocol now has an attribute with the name of the protocol in
the config tag. Each of these attributes accepts one of four possible values:
* no - do not print out this protocol
* name - print only the protocol name
* default - print a short summary of the most important header values
* all - print all available header values
Example:
! <config eth="name"
! arp="all"
! ipv4="default"
! dhcp="no"
! icmp="all"
! udp="no"
! tcp="default"
! ... />
Corresponding output example:
! ETH IPV4 10.0.2.212 > 10.0.2.55 time 7158 ms (Δ 11 ms)
! ETH IPV4 10.0.2.55 > 10.0.2.201 TCP 80 > 49154 flags ' time 6976 ms (Δ 5 ms)

Issue #2738
Nitpicker's 'Session:focus' call used to trigger a one-off focus change
at call time. This focus change did not pass the same code paths as a
focus change triggered by a "focus" ROM update, which led to
inconsistencies.
This patch changes the implementation of 'Session::focus' such that the
relationship of the caller and the focused session is preserved after
call time. Whenever the calling session is focused in the future, the
specified session will receive the focus instead. So 'Session::focus'
represents no longer a single operation but propagates the information
about the inter-session relationship. This information is taken into
account whenever the focus is evaluated regardless of how the change is
triggered.
This makes the focus handling in scenarios like the window manager more
robust.
Issue #2746
Relative motion events with a motion vector of (0,0) should not exists.
They cause jittery movements of nitpicker's pointer position. This
patch filters out such events.
Our static okl4 system-integration configuration specifies a fixed RAM
range from 32 to 800 MiB, which must be satisfied by Qemu or strange
errors happen due to accesses beyond RAM. (Fixes current issues with
nic_router.run.)
This tests ping with simple IP forwarding, ping with NAPT as well as
forwarding of ICMP "Destination Unreachable" messages through the NIC
router.
Issue #2732
The 'ping' component continuously sends ICMP Echo requests to a given IP host
and waits for the corresponding ICMP Echo replies. For each successfull ICMP
Echo handshake it prints a short statistic. By now, it can be used only with a
static IP configuration. The size of the ICMP data field can be configured. It
gets filled with the letters of the alphabet ('a' to 'z') repeatedly.
Issue #2732
Originally, the timeout framework caused deadlocks when acquiring the same
lock from different timeout handlers. This use case is now tested in the
timeout test.
Fixes#2704
