We call curl a second time if the first check fails. This gives download

The input_filter is the successor of the input_merger. In addition to

Put the initialization of the cpu cores, setup of page-tables, enabling of
MMU and caches into a separate component that is only used to bootstrap
the kernel resp. core.

Instead of implicitly asking for core's link address when linking
core within the run tool, deliver it explicitly to the build_core
routine. Thereby we gain the freedom to use the build_core tool for
different targets like core, and bootstrap.

This test reproduces an issue of the VFS block file system when the
underlying block device has a coarser granularity than the block
requests issued by the VFS client. I.e., if the underlying block device
has a block size of 4K, writing a sequence of (non-4K-aligned) 512 blocks
that crosss a 4K boundary corrupts the data on the block device.

Ref #2190
This patch make the ABI mechanism available to shared libraries other
than Genode's dynamic linker. It thereby allows us to introduce
intermediate ABIs at the granularity of shared libraries. This is useful
for slow-moving ABIs such as the libc's interface but it will also
become handy for the package management.
To implement the feature, the build system had to be streamlined a bit.
In particular, archive dependencies and shared-lib dependencies are now
handled separately, and the global list of 'SHARED_LIBS' is no more.
Now, the variable with the same name holds the per-target list of shared
libraries used by the target.
This commit adds support for testing multiple kernels within the same
build directory. In addition to the existing -p arguments, the new
version expects one or more -k arguments that denote the kernels to be
used for executing the specified run scripts.
Consequently, the autopilot executes the 3-dimensional matrix of
platforms x kernels x run scripts, e.g.,
autopilot --force -p x86_32 -k nova -k okl4 -k sel4 -k linux -r log
Issue #2190
This patch makes the benefit of the recently introduced unified Genode
ABI available to developers by enabling the use of multiple kernels from
within a single build directory. The create_builddir tool has gained a
new set of kernel-agnostic platform arguments such as x86_32, or panda.
Most build targets within directories are in principle compatible with
all kernels that support the selected hardware platform. To execute a
scenario via the run tool, one has to select the kernel to use by
setting the 'KERNEL' argument in the build configuration
(etc/build.conf). Alternatively, the 'KERNEL' can be specified as
command-line argument of the Genode build system, e.g.:
make run/log KERNEL=nova
This allows us to easily switch from one kernel to another without
rebuilding any Genode component except for the very few kernel-specific
ones.
The new version of the 'create_builddir' tool is still compatible with
the old version. The old kernel-specific build directories can still be
created. However, those variants will eventually be removed.
Note that the commit removes the 'ports-foc' repository from the
generated 'build.conf' files. As this is only meaningful for 'foc',
I did not want to include it in the list of regular repositories (as
visible in a 'x86_32' build directory). Hence, the repository must
now be manually added in order to use L4Linux.
Issue #2190
This patch removes possible ambiguities with respect to the naming of
kernel-dependent binaries and libraries. It also removes the use of
kernel-specific global side effects from the build system. The reach of
kernel-specific peculiarities has thereby become limited to the actual
users of the respective 'syscall-<kernel>' libraries.
Kernel-specific build artifacts are no longer generated at magic places
within the build directory (like okl4's includes, or the L4 build
directories of L4/Fiasco and Fiasco.OC, or the build directories of
various kernels). Instead, such artifacts have been largely moved to the
libcache. E.g., the former '<build-dir>/l4/' build directory for the L4
build system resides at '<build-dir>/var/libcache/syscall-foc/build/'.
This way, the location is unique to the kernel. Note that various tools
are still generated somewhat arbitrarily under '<build-dir>/tool/' as
there is no proper formalism for building host tools yet.
As the result of this work, it has become possible to use a joint Genode
build directory that is usable with all kernels of a given hardware
platform. E.g., on x86_32, one can now seamlessly switch between linux,
nova, sel4, okl4, fiasco, foc, and pistachio without rebuilding any
components except for core, the kernel, the dynamic linker, and the timer
driver. At the current stage, such a build directory must still be
created manually. A change of the 'create_builddir' tool will follow to
make this feature easily available.
This patch also simplifies various 'run/boot_dir' plugins by removing
the option for an externally hosted kernel. This option remained unused
for many years now.
Issue #2190
This patch decouples the kernel-specific implementation of the dynamic
linker from its kernel-agnostic binary interface. The name of the
kernel-specific dynamic linker binary now corresponds to the kernel,
e.g., 'ld-linux.lib.so' or 'ld-nova.lib.so'. Applications are no longer
linked directly against a concrete instance of the dynamic linker but
against a shallow stub called 'ld.lib.so'. This stub contains nothing
but the symbols provided by the dynamic linker. It thereby represents
the Genode ABI.
At system-integration time, the kernel-specific run/boot_dir back ends
integrate the matching the kernel-specific variant of the dynamic linker
as 'ld.lib.so' into the boot image.
The ABI symbol file for the dynamic linker is located at
'base/lib/symbols/ld'. It contains the joint ABI of all supported
architectures. The new utility 'tool/abi_symbols' eases the creation of
such an ABI symbol file for a given shared library. Its result should be
manually inspected and edited as needed.
The patch removes the 'syscall' library from 'base_libs.mk' to avoid
polluting the kernel-agnostic ABI with kernel-specific interfaces.

Instead of solving the problem to deliver ROM modules to core while booting
differently for the several kernels (multi-boot, elfweaver, core re-linking),
this commit unifies the approaches. It always builds core as a library, and
after all binaries are built from a run-script, the run-tool will link an
ELF image out of the core-library and all boot modules. Thereby, core can
access its ROM modules directly.
This approach now works for all kernels except Linux.
With this solution, there is no [build_dir]/bin/core binary available anymore.
For debugging purposes you will find a core binary without boot modules, but
with debug symbols under [run_dir].core.

A run script to demonstrate the combination of the cpu_sampler, fs_log,
ram_fs and noux components for saving the sampled data in files and

Issue #2044
When running the same kernel in a VM as on the host system and the
kernel boot message from the VM appears on the log output, the run tool
assumes that the host machine has rebooted unexpectedly. With this
commit, an unexpected reboot is assumed only if the kernel boot message
appears at the beginning of a line. On base-hw, we enforce a line feed
at the beginning of the boot message as the SPIKE emulator log starts
with the first message of the kernel lacking a line feed.
Fixes#2041
This patch equips the build system with the feature of building an
individual library with its dependencies by specifying the library
as 'LIB' argument. E.g., 'make LIB=libc' builds the libc.
This is a generalisation approach of the hw_zynq target. As the boards
typically use UART1 instead of UART0 (used by qemu), we have to
distinguish between those. Moreover, in general hw_zynq does not imply
zynq_qemu anymore, so that the support of particular boards can be
placed in third-party or community repositories (e.g. Genode world).
Fixes#1926
If ports need preparation in order to execute a run script, use the
knowledge about the actual genode directory to suggest a command to the
user that can be directly copied to the command line.
Previously, ports that were needed for a scenario and that were not
prepared or outdated, triggered one assertion each during the second
build stage. The commit slots a mechanism in ahead that gathers all
these ports during the first build stage and reports them in form of a
list before the second build stage is entered. This list can be used
directly as argument for tool/ports/prepare_port to prepare respectively
update the ports. If, however, this mechanism is not available, for
example because a target is build without the first build stage, the old
assertion still prevents the target from running into troubles with a
missing port.
Fixes#1872
To raise readability when preparing multiple ports in parallel we prefix
also the git clone output with the port name dark-yellow-coloured. To
achieve this we sed the git output. In sed \x1b[ resolves to an escape
sequence and \033[, that we use normally, doesn't. The echo command, at
the other hand, resolves both to an escape sequence. Thus we use the
sed-compatible version in general. This commit inhibits the progress
output of git clone as it can't be redirected to sed.
Ref #1872
The tool/prepare_port tool is now able to handle a list of ports that
shall be prepared. Additionally, one may state the number of ports that
shall be prepared in parallel at a max by using the -j parameter. If -j
is not set by the user, the tool acts as with -j1. The previous
implementation of the tool that prepares only a single port was moved to
tool/ports/mk/prepare_single_port.mk and acts as back end to the new
prepare_port tool. The interface of the new prepare_port tool is
backwards compatible. When called for one port only, the behavior is the
same as when calling tool/ports/mk/prepare_single_port.mk directly.
Removes "usage" rule from prepare_single_port.mk. Removes shebang line
from prepare_single_port.mk.

This is a requirement to implement support for MSI on hw_x86_64_muen.
Enable automatic build of Muen system image by adding the image/muen run

--image-muen-components Muen system components
--image-muen-hardware Muen hardware platform
--image-muen-gnat-path Path to GNAT toolchain
--image-muen-spark-path Path to SPARK toolchain
This enables installation of the bootloader image without wiping the
partition table which is needed at least for the tz_vmm tutorial with
hw_usb_armory.

Causes trouble if a gz image is loaded via grub and later used as initrd for a
Linux VM (e.g. with Seoul VMM)
Discovered during Turmvilla scenario #1552 and issue #1733.
To make the creation of a bootstrap medium for most ARM platforms more
comfortable this tool shall bundle all the different U-Boot source
states, patches, and MMC preparation rules that we gathered over the
year for that purpose. As input, the tool merely needs the targeted
platform (analogous to the platform parameter of 'create_builddir'). By
now, 'hw_wand_quad' is the only supported platform. Further platforms
can be added successively. As output, the tool creates a head image file
of small size (8MiB) that can be copied (dd) with offset 0 to the MMC.

This makes use of the iPXE sanboot command [1] which downloads and

iPXE is an open source network boot firmware which supports booting from
a web server via HTTP [1].
The following two parameters can be used to specify the iPXE/HTTP setup:
--load-ipxe-base-dir
This parameter specifies the base directory of the HTTP server from
which the target machine downloads the files.
--load-ipxe-boot-dir
The directory relative to iPXE base dir which contains the iPXE
chainload configuration and all necessary files.
The target machine is expected to request the following iPXE
configuration via HTTP:
http://${HOST_URL}/${ipxe-boot-dir}/boot.cfg
This can be achieved by building iPXE with the following embedded
script:
#!ipxe
dhcp
chain http://${HOST_URL}/${ipxe-boot-dir}/boot.cfg

The commit consumes the argument of a unsupported printf command.
Without the commit - a subsequent command uses the argument of the preceding
command, which may cause memory corruption or page faults for sequences using
string commands, e.g.
Genode::printf("%#x %s\n", 0x20, "Test");
'#' is not supported by Genode::printf. In this scenario a pagefault at
address 0x20 is caused.

Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

The plugin works just like the netio plugin and uses the following
parameters
--power-off-energenie-host network address of device
--power-off-energenie-password password for device
--power-off-energenie-port target port of device
The run plugin is not generic and works for NETIO4/NETIO230 powerplugs
only. Further, this opens the path for other vendor-specific powerplug
plugins.
Note, the plugin parameter for the addressed powerplug was renamed to
--power-on-netio-host resp.

If a user has e.g. /tftpboot/x86 as directory and configures
base_dir=/tftboot and offset_dir=/x86, this leads to bad behavior
as the load module creates a symlink
/tftpboot/x86/<builddir> -> <absolut_builddir>
in this case instead of the desired
/tftpboot/x86 -> <absolut_builddir>
Furthermore, the module works on
/tftpboot/x86/config-00-00-00-00-00-00
and
/tftpboot/x86/<builddir>/config-00-00-00-00-00-00
afterwards, which looks bad too. As there is no warning at all, this can
be hard to debug. The commit adds an appropriate check with error message and
exit -1 on an existing directory.

If just one multiboot kernel module was loaded after bender, the

before ELF loading.

Bender upstream issue is TUD-OS/morbo#4
The base-hw kernel on x86_64 currently assumes 254 MiB of RAM. The RAM
region is subtracted from the I/O mem allocator and therefore this range
is not available for device I/O.
If qemu is started with -m 128, the region for (emulated) PCI config
space access lies within this region and I/O mem allocation in the
pci_drv will fail. Giving qemu more RAM moves the PCI config space out
of the 254 MiB region, making the run/libc_ffat scenario with acpi work.
