Always instantiating a network device with id `net0`, removes the need to call
append_qemu_nic_args in run scripts unless we want to add forwarding
rules.
genodelabs/genode#4311
Allow specifying additional qemu arguments for externally supported boards
(e.g. zynq_qemu) by adding a `qemu_args` file in the board-property directory.
The syntax of the qemu_args file is as follows:
- Arguments can appear in a single line or in multiple lines as the
lines will be appended (separated by a whitespace) to the global
qemu_args variable.
- If the line is prepended with a `foobar:` expression. The arguments
are only added if the foobar spec is present.
Note, that a `-m` argument specified in the qemu_args file will
override the arguments provided by the run scripts.
genodelabs/genode#4311
* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile
* Move board-specific directories in base-hw out of specs
The new helper function returns a boolean value analoque to 'have_spec' if the
BOARD variable corresponds to the given value. It shall replace [have_spec <board>]
declarations in run-scripts.
Ref #3971
The driver is faily simple and does not support fancy features like
TCP checksum offloading or vlan filtering, but it is fully capable of
running every Genode network based scenario I've tried. Its currently
known to work on virt_qemu arm platforms and x86_64.
Fix#3825
Right now the same code dealing with nic setup on qemu is duplicated
in many different run scripts. It makes it unnecesarily complex to
change the existing config or add support for new nic types. Lets move
all this common code to qemu.inc.
Ref #3825
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'.
