3be0136901 base: add util/dictionary.h utility
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.

7d143087c9 xml_node: change with_sub_node signature
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.

f1f0ee3a21 base: disregard ld.lib.so stub as build artifact
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.

9aab61f5a7 mk: allow declaration of build artifacts for libs
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.

c560285d88 build: support library builds via lib/<libname>
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.

88118b133a intel_fb: request copy of Intel opregion
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

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

setup all connectors on a Fujitsu U7411 docking station.

c38b71146b trace_buffer: only iterate after initialization
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.

determined on a Cortex-A9 (Zynq-7000) SoC @ 666Mhz. It is best combined

offset 7). Yet, even without L2 prefetching this seems to be the sweet

be0a1742ac base: distinct TRACED from ATTACHED trace subjects
This patch makes the trace-subject state as reflected to the trace
monitor more accurate.

Until now, a subject could be in UNTRACED or TRACED state. In reality,
however, there exists an intermediate state after the trace monitor
called 'trace' for the subject but before the subject locally activated
the tracing (done when passing a trace point). This intermediate state
was reflected as UNTRACED. Consequently, threads that never pass a trace
point (e.g., just waiting for I/O) would remain to appear as UNTRACED
even after enabling its tracing by the trace monitor. This is confusing.

This patch replaces the former UNTRACED and TRACED states by three
distinct states:

  UNATTACHED  prior any call of 'trace'
  ATTACHED    after a trace monitor called 'trace'
              but before the tracing is active
  TRACE       tracing is active

This commit simplifies the current implementation by overloading the

c2efa5406e xml_node: support backslash as attribute value
XML allows attribute values like <node attr="\"/>. The XML parser
wrongly reflects this case as 'Invalid_syntax'. This behavior stems from
the implicit use of the 'end_of_quote' function, which considers the
sequence of '\"' as a quoted '"' rather than the end of a quoted string.

The patch solves this problem by making the 'end_of_quote' part of
the tokenizer's scanner policy.

The patch removes the 'end_of_quote' function from 'util/string.h'
because it is not universal, and to avoid the ambiguity with
'SCANNER_POLICY::end_of_quote'.

494f881f27 core: don't use frame 0 for managing_system pd
When a PD owns the right to ask for a RAM dataspace's `dma_addr` it is
concurrently constrained to use allocations of a specific physical RAM area.
This commit further limits this area by removing RAM page frame zero.
Otherwise the return value of `dma_addr` for such a dataspace would be
erroneously interpreted as a fault, because zero is currently the error
return value of `dma_addr`.

e4f62380d7 base: Pd_session::dma_addr, Pd_session::attach_dma
This patch enhances the PD-session interface with the support needed for
user-level device drivers performing DMA. Both RPC functions are
intended for the direct use by the platform driver only. If invoked for
PDs that lack the managing-system role, the operations have no effect.

The 'dma_addr()' RPC function allows the platform driver to request the
DMA address of a given RAM dataspace. It is meant to replace the
'Dataspace::phys_addr' RPC function.

The 'attach_dma' RPC function adds the given dataspace to the device
PD's I/O page table. It replaces the former heuristics of marking DMA
buffers as uncached RAM on x86.

With this patch, the UNCACHED attribute of RAM dataspaces is no longer
used to distinguish DMA buffers from regular RAM dataspaces.

88ca8d1a72 base: fix potential memory leak in allocator_avl
When used by the 'Allocator_avl' the slab allocator's backing store is
dynamically disabled and re-enabled while adding/freeing ranges.
However, during those operations, slab entries can be freed. This,
in turn, can result in the release of a slab block (when the freed slab
entry happens to be the last entry of the block). In this corner case,
'Slab::_release_backing_store' operation has no effect because no
backing-store allocator is set. As a result, the block is no longer
referenced but not physically freed.

The patch fixes the problem by skipping '_free_curr_sb' whenever
no backing store is defined. So the completely empty block remains
in the working set.

27b798fa4f base: Make int to access_t conversion explicit.
As far as I can tell this is not raised by any released GCC versions.
Clang 13 on the other hand warns about it due to implicit-int-conversion
warning which is automatically enabled together with Wconversion. The
problem is relatively simple, shifting access_t value does not always
produce result which is also of access_t type. For example, if access_t
is uint16_t, shifting it will produce integer result. This can be
observed even with GCC. Building the following C++ example will fail:

  #include <type_traits>
  #include <stdint.h>

  int test() {
      uint16_t a = 0xabcd;
      static_assert(std::is_same_v<decltype(a<<1), uint16_t>);
      return 0;
  }

Changing uint16_t in the static_assert to int, will allow the code to
build.

Make such int to access_t implicit conversion explicit to allow the code
to be compiled with both GCC and clang.

3cc6df3116 base: tighten affinity handling
This patch improves the robustness of the CPU-affinity handling.

- The types in base/affinity.h received the accessors
  'Location::within(space)' and 'Affinity::valid', which alleviates
  the fiddling with coordinates when sanity checking the values,
  in init or core.

- The 'Affinity::Location::valid' method got removed because its
  meaning was too vague. For sanity checks of affinity configurations,
  the new 'within' method is approriate. In cases where only the x,y
  values are used for selecting a physical CPU (during thread creation),
  the validity check (width*height > 0) was not meaningful anyway.

- The 'Affinity::Location::from_xml' requires a 'Affinity::Space'
  as argument because a location always relates to the bounds of
  a specific space. This function now implements the selection of
  whole rows or columns, which has previously a feature of the
  sandbox library only.

- Whenever the sandbox library (init) encounters an invalid affinity
  configuration, it prints a warning message as a diagnostic aid.

- A new 'Affinity::unrestricted' function constructs an affinity that
  covers the whole affinity space. The named functions clarifies
  the meaning over the previous use of the default constructor.

- Core's CPU service denies session requests with an invalid
  affinity parameter. Previously, it would fall back to an
  unrestricted affinity.

13dab699b1 base: invalidate entire range on VM-session detach
The requested guest-physical memory range may comprise multiple attached
dataspace regions, which must all be detached. This is not required for
the current vbox5 implementation, but for vbox6 as the current API
suggests these semantics.

This commit can be seen as intermediate fix as a real fix should change
the API to prevent long-running detach loops in core that may lock out
requests by other components.

dc39a8db62 base: introduce Allocator::try_alloc
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.

To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.

522a1cdc5b tool/run: read board-specific qemu args from file
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.

c38c2a6455 cxx: missing operator delete with align_val_t arg
When rebasing my local branch on top of sculpt-21.10 tag I've noticed
two problems.

The code in new_delete.cc does not include new header file. This works
fine with GCC, but fails with clang because std::align_val_t type is
not defined anywhere according to clang. It looks like GCC pulls this
header indirectly somehow.

The second problem can be seen if one disallows undefined symbols in
executables and shared_libraries. This can be seen with both GCC and
clang by adding --no-undefined to LD_OPT. With such change in place core
fails to link due to:

ld.lld: error: undefined symbol: operator delete(void*, std::align_val_t)
>>> referenced by thread.h:448 (/home/tworaz/devel/genode/repos/base-hw/src/core/kernel/thread.h:448)
>>>               thread.o:(Kernel::Core_main_thread::~Core_main_thread()) in archive debug/core-hw-virt_qemu.a
>>> referenced by thread.h:448 (/home/tworaz/devel/genode/repos/base-hw/src/core/kernel/thread.h:448)
>>>               thread.o:(non-virtual thunk to Kernel::Core_main_thread::~Core_main_thread()) in archive debug/core-hw-virt_qemu.a
>>> did you mean: operator delete(void*, unsigned long, std::align_val_t)
>>> defined in: debug/core-hw-virt_qemu.a(supc++.o)

If the code would somehow manage call such undefined symbol it'd crash.
Since I generally prefer link time failures to runtime crashes I link
all genode binaries with --no-undefined.

To fix this problem just add a dummy implementation of missing delete
operator.
