On each execution the output buffer is overriden when run_genode_until
is executed multiple times. Run scripts, that depend on extracting
information after several execution steps, e.g. noux_net_netcat, will
fail to do so. Therefore, we append the newly captured log output to
the old output buffer.
Issue #1327.
A Nic::Session client can install a signal handler that is used to
propagate changes of the link-state by calling 'link_state_sigh()'.
The actual link state is queried via 'link_state()'.
The nic-driver interface now provides a Driver_notification callback,
which is used to forward link-state changes from the driver to the
Nic::Session_component.
The following drivers now provide real link state: dde_ipxe, nic_bridge,
and usb_drv. Currently, OpenVPN, Linux nic_drv, and lan9118 do not
support link state and always report link up.
Fixes#1327
If a client acknowledges the same packet more than once, the packet also
gets freed more than once. At the second attempt the underlaying
Bit_array will throw an 'Invalid_clear' exception, which results in an
uncaught exception that leads to an abort() call in the freeing
component.
Fixes#1462.
To ease debugging without the need to tweak the kernel every time, and to
support userland developers with useful information this commit extends several
warnings and errors printed by the kernel/core by which thread/application
caused the problem, and what exactly failed.

The driver for the Freescale eSDHCv2 doesn't support the highest
available bus frequency by now and also the bus width may be set to a
higher value but that needs further checks on the capabilities of the
inserted card.
The commits provide a benchmark as it exists for the OMAP4 SDHC driver.
Fix#1458
The 'continue_hw_accelerated' assertion at the end of the recall handler
can fail in situations which are not problematic, for example if the
'Timer' thread has set the 'VMCPU_FF_TIMER' flag in the meantime and
requested a recall afterwards. Since we don't know for sure if a recall is
requested for the other flags as well, the assertion gets replaced by a
debug message, which gets printed if any of the 'not yet verified as safe'
flags is set.
Fixes#1426
The GUID partition table (GPT) is primarily used by systems using
(U)EFI and is a replacement for the legacy MBR. For now, the current
implementation is able to address up to 128 GUID partition entries
(GPE).
To enable the GPT support in 'part_blk' it has to be configured
accrodingly:
! <start name="part_blk">
! [...]
! <config use_gpt="yes">
! [...]
! </start>
If 'part_blk' is not able to find a valid GPT header it falls back
to using the MBR.
Current limitations:
Since no endian conversion takes place it only works on LE platforms
and of all characters in the UTF-16 encoded name field of an entry
only the ones included in the ASCII encoding are printed. It also
ignores all GPE attributes.
Issue #1429.
The hover reports provides information about the session currently
pointed-to, i.e., hovered session. It can be enabled by the 'hover'
attribute of nitpicker's 'report' configuration element
<report hover="yes" />
Fixes#1442
The bindings for 32bit did not consider that in the syscall_3 function
edx changes due to the assembly instructions and that in the syscall_4
function edx and ecx change. So, the compiler wrongly assumed that the
content of these registers stayed unchanged.
Fixes#1447
In the past, unmap sometimes occured on RM clients that have no thread,
PD, or translation table assigned. However, this shouldn't be the
case anymore.
Fixes#504
* Introduce hw-specific crt0 for core that calls e.g.: init_main_thread
* re-map core's main thread UTCB to fit the right context area location
* switch core's main thread's stack to fit the right context area location
Fix#1440
The 'check_port_source' checks whether all remote sources defined for a given
port are currently available. It returns zero, when all remote resources are
available.
Fix#1430
This decouples the size of the mode transition control region from the
minimal mapping size of the page tables implementation. Rather, the CPU
architecture is able to specify the actual size.
Rationale: For x86_64, we need the mtc region to span two pages in order
to store all the tables required to perform the mode switch.
