- build debug version of core and bootstrap found under
_var/run/<runscript>.core_ (.bootstrap). This is a regression when
switching from object to archive library linkage of core.
fixes#4027
Do not link base and core libraries into on large relocatable .o file,
which is linked later to core - causing long link times. Create an
independent library archive out of the base and core libraries that can
be linked faster.
issue #4027
This patch moves the bootstrap-link-address information from the
tool/run/boot_dir/hw file to board-specific property files that can be
accessed by using the board as key. This eliminates the need to
customize boot_dir/hw when hosting board-support in an external
repository.
Fixes#3998
* 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
This patch adds support for booting base-hw kernel on qemu-arm virt
machines. The arm_virt machine has 2GB of RAM, 2 Cortex A15 cores and
uses GICv2 interrupt controller. The arm_64_virt machine also has 2GB of
RAM, but has 4 Cortex A53 cores and uses GICv3. Both machines use PSCI
to boot additional CPU cores.
Fixes#3673
Components like kernel, core, and bootstrap that are built for a
specific board need to reside inside the same architectural dependent
build directory. For instance there are sel4, foc, and hw kernel builds
for imx6q_sabrelite and imx7d_sabre, which have to reside inside the same
arm_v7 build directory.
This commit names those components explicitely, and adapts the run-tool to it.
Fix#3316
* To base-hw/recipes/src add base-hw-arndale, base-hw-imx53_qsb,
base-hw-imx53_qsb_tz, base-hw-odroid_xu, base-hw-panda, base-hw-rpi,
base-hw-wand_quad
* Ensure that the correct base-hw recipe is choosen by the run module
'boot_dir/hw'
This commit changes the semantic of run_boot_dir to link a core
binary with debug symbols only when the designated library is in place.
Follow-up fix refering to issues #2339 and #2700
* introduce new syscall (core-only) to create privileged threads
* take the privilege level of the thread into account
when doing a context switch
* map kernel segment as accessable for privileged code only
Ref #2091
* introduces central memory map for core/kernel
* on 32-bit platforms the kernel/core starts at 0x80000000
* on 64-bit platforms the kernel/core starts at 0xffffffc000000000
* mark kernel/core mappings as global ones (tagged TLB)
* move the exception vector to begin of core's binary,
thereby bootstrap knows from where to map it appropriately
* do not map boot modules into core anymore
* constrain core's virtual heap memory area
* differentiate in between user's and core's main thread's UTCB,
which now resides inside the kernel segment
Ref #2091
Previously, the debugging version of the core image
(<build_dir>/var/run/<run_name>.core) was created by the run tool from
the common core object file
(<build_dir>/var/run/<run_name>/core-<kernel>.o). This object file,
however, was already stripped by the build system and thus didn't
contain debug info anymore. The build system also creates an unstripped
version in <build_dir>/debug/core-<kernel>.o, so we now use this one
for <build_dir>/var/run/<run_name>.core.
Ref #2254
This way, files copied from the depot are incorporated in addition to
the files explicitly specified as boot modules.
The patch also adds an automatic check for the validity of the XML
syntax of boot modules ending with '.config'.
Issue #2339
Run scripts can use the new 'import_from_depot' function to incorporate
archive content from the depot into a scenario. The function must be
called after the 'create_boot_directory' function and takes any number
of pkg, src, or raw archives as arguments. An archive is specified as
depot-relative path of the form <user>/<type>/name. Run scripts may
call 'import_from_depot' repeatedly.
An argument can refer to a specific version of an archive or just the
version-less archive name. In the latter case, the current version (as
defined by a corresponding archive recipe in the source tree) is used.
If a 'src' archive is specified, the run tool integrates the content of
the corrsponding binary archive into the scenario. The binary archives
are selected according the spec values as defined for the build directory.
As of now, only x86_32 and x86_64 are supported by the 'depot_spec'
function.
Issue #2339
By installing the core object to bin/, we follow the same convention as
for regular binaries. This, in turn, enables us to ship core in a
regular binary archive. The patch also adjusts the run tool to pick up
the core object from bin/ for the final linking stage.
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.
Ref #2092
This commit mostly removes the globally visible NR_OF_CPUS define
from the global makefile specifiers defined in the base-hw repository.
Whereever necessary it adds platform specific makefiles to the base
repository when they were missing.
Ref #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.
