Adrian-Ken Rueegsegger 8c9b79fab0 hw: Use properly sized asm type in boot_modules.s
The boot modules assembled by the generated boot_modules.s file is
accessed from core using struct Bm_header. Unfortunately the assembler
.long directive is synonym to .int [1] and thus has the same size as the
C++ int type and *not* long. Use the matching assembly type .quad in
boot_modules.s when generating the file for 64-bit platforms such as

Norman Feske a974726e26 hw: skeleton for building on x86_64
This patch contains the initial code needed to build and bootstrap the
base-hw kernel on x86 64-bit platforms. It gets stuck earlier
because the binary contains 64-bit instructions, but it is started in
32-bit mode. The initial setup of page tables and switch to long mode is
still missing from the crt0 code.

Josef Söntgen e6cf426d72 run: always append to output buffer
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.

Josef Söntgen dd47129bef nic session: link-state change handling
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

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.

The driver for the Freescale eSDHCv2 doesn't support the highest

Christian Prochaska dac3efcc02 vbox: replace too strict assertion with debug message
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.

Josef Söntgen 9b7e0ce0a5 part_blk: add GPT support
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

To enable the GPT support in 'part_blk' it has to be configured

! <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.

Alexander Boettcher 2a4b67f90b nova: fix syscall bindings for 32bit
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.
