pci_decode: report devices from ACPI info
We still provide an empty <devices> node as the file itself is used by
platform agnostic run scripts.
Some signal-heavy scenarios (e.g., libc_integration) produced the
following warning that hinted a data race on signal data in the context
object.
Warning: returning signal with num == 0
The cause was the use of Signal_context::local_submit() in the libc
introduced in
424ed1b79a libc: remove Reconstructible / use local_submit in kernel
in combination with a missing context-mutex aquisition resulting in a
data race on Signal_context::_curr_signal.
Issue #3923
This prevents errors like the following during parallel builds.
MERGE ld-hw.abi.so
/usr/local/genode/tool/21.05/bin/genode-arm-ld:symbol.map:0: syntax error in VERSION script
Try to allocate within constraint area first. In case the area is exhausted,
try allocation at other memory locations.
The motivation for this is to limit DMA allocations to 4GB (since some
devices require addresses below 4GB). On some platforms there is little
physical RAM in this area (<1GB) and the constrainted area exhausts. In
case an IOMMU is present, RAM at higher locations can still be mapped
below 4GB, which is done in the platform drivers.
issue #4665
With "grub2: update to newer grub2 2.06 version" a regression slipped in
which makes the ISO not bootable on real hardware. The commit reverts to
the previous behaviour, to load the GRUB2 modules after boot later one by
one in the ISO format case.
Fixes#4647
This commit fixes two issues with the timeout lib and the base-hw src recipe:
* Add source files of timeout lib to recipe content.
The files weren't copied to the depot until now. However, the archive
nonetheless built successfully because of the second issue that is described
below.
* Get rid of the usage of the BASE_DIR variable in the timeout lib.
The BASE_DIR variable always resolves to the repos/base directory even when
building in a depot. That said, the use of BASE_DIR in make-files that are
not part of the build system itself must be avoided. Instead, REP_DIR,
REP_INC_DIR, and $(call select_from_repositories, ...) should be used.

When creating an Irq connection to a component (not core), e.g. a pin
driver, we typically need a to provide a session label in order to apply
a session policy and to distinguish multiple sessions from the same
component.
genodelabs/genode#4606
The new 'Dictionary' provides an easy way to access objects using
strings as key. The 'String' received the 'operator >' to simplify the
organization of strings in an AVL tree.
The patch removes the former definition of the 'operator >' from the
platform driver because it would be ambigious now.
Fixes#4610
The `with_sub_node` method is renamed to `with_optional_sub_node` to
better reflect that the non-existence of a sub node with the desired type is
ignored.
At the same time, the new `with_sub_node` now takes a second functor that is
called when no sub node of the desired type exists.
genodelabs/genode#4600
The ld.lib.so stub library generated by base/lib/mk/ld.mk has no
purpose at runtime. On the contrary, it must not be integrated into the
boot image because its name collides with the kernel-specific dynamic
linker.
The build system automatically announces the names of shared libraries
as build artifacts. However, in rare cases, it is required to manually
define them. In particular, the 'ld' stub library plays no role at runtime
and should not be integrated into the boot image.
This patch adds a customization hook following the same pattern as used
for target.mk files, namely the BUILD_ARTIFACTS variable. If defined,
its value is taken as the list of boot artifacts generated by the
library-description file.
Issue #4368
This patch adds special handling for lib/<libname> arguments to the
build system, which supersedes the former LIB=<libname> mechanism.
Whereas the old mechanism was limited to a single library, the new
convention allows multiple library arguments, similar to regular
targets. The change brings the two immediate benefits.
First, the streamlining of library and target arguments allows for the
building of libraries via the 'build' command of the run tool.
Second, it alleviates the need for pseudo target.mk files for building
shared libraries that have no direct dependencies, in particular VFS
plugins.
Since this change eases the explicit creation of shared libraries
from run scripts, we may reconsider the automatic implicit building
of shared libraries driven by targets. E.g., while developing a Qt
application, a run script could import the Qt libraries from the
depot and combine those with the developed (fresh built) target without
triggering the build of the Qt libraries in the build directory.
When issueing 'make' without arguments, all targets are built. This
patch applies this behavior to libraries as well, thereby removing the
need for the base/src/lib/target.mk pseudo target as used by the CI
tools to build all libraries.
Note that target.mk files located under src/lib/ are no longer
reachable. Therefore, all run scripts that used to trigger the
build of a shared library via a pseudo target must be adapted.
E.g., 'build lib/vfs/tap' must be replaced by 'build lib/vfs_tap'.
With this patch, the LIB=<libname> option is no longer supported.
Fixes#4599
Instead of having a generic "virt_qemu" board use "virt_qemu_<arch>" in
order to have a clean distinction between boards. Current supported
boards are "virt_qemu_arm_v7a", "virt_qemu_arm_v8a", and
"virt_qemu_riscv".
issue #4034
The link dissolve timeout is updated for every packet, which leads to
trigger_once() RPCs that only marginally change the scheduled timeout but
significantly slow down the packet throughput.
genodelabs/genode#4555
acpica and the Intel display driver tries to use the Intel Opregion
simultaneously on Genode, which is not supported nor wanted for IO_MEM region as
which it is handled.
Attempts to remove the access to the region was not successful, since some
SSDT table contains ACPI AML code which is executed regularly and read/write
the Opregion.
The patch adds support to read in a copy of the Intel Opregion done by the
acpi_drv component. The copy was sufficient to make the Intel display driver
working to find and lookup the Intel VBT (video bios table) information to
setup all connectors on a Fujitsu U7411 docking station.
Fixes#4531
Build description files that feature both an actual target and
CUSTOM_TARGET_DEPS happen to re-link the target each time whenever one
of the CUSTOM_TARGET_DEPS is phony, e.g., gems/src/app/menu_view/.
The re-linking of the actual target is of course not desired. By
triggering the creation of CUSTOM_TARGET_DEPS from 'all:' instead of
'$(TARGET)', the specified files do not implicitly become link
dependencies of the target.
Issue #3972
There is a race between the trace subject doing the buffer
initialization and the monitor trying to iterate the buffer entries. If
the monitor tries to iterate entries of an uninitialized buffer, it will
read the very first entry twice. The monitor should therefore only start
iteration when the buffer has been initialised.
genodelabs/genode#4513
After reverting unused ranges during allocator destruction
'_meta_data.free_empty_blocks' may lead to more unused ranges because
meta data blocks maybe freed where the meta data for the blocks is
managed by other meta data blocks. This leads to dangling allocation
warnings which are caused by meta data. Therefore, we call
'_revert_unused_ranges' and 'free_empty_blocks' until no more ranges
can be freed.
