This reference member is not used anywhere in the code. This prompts
clang to complain about it. Eliminate the member and all the plumbing
associated with it to silence the warning.
Issue #4421
Clang really doesn't like char subscripts. I can't say I blame it. Fix
the warning by an explicit cast to unsigned.
include/nitpicker_gfx/tff_font.h:230:53: error:
array subscript is of type 'char' [-Werror,-Wchar-subscripts]
Tff::Vertical_metrics const m = _vertical_metrics['m'];

Issue #4421
Clang likes to complain when lambdas capture parameters without
actually using them. This patch fixes a couple of such problems in VFS
related os module code.
Issue #4421
The soft ABI implies purely software floating point implementation.
This is not the case for Genode however. For example core's
exception_vector.S uses vmsr instruction. This builds fine with with
GCC based toolchain, but clang with integrated-as complains:
src/core/spec/arm/exception_vector.S:122:2: error: instruction requires: VFP2
vmsr fpexc, r1
^
Fix this by passing softfp to mfloat-abi command on ARMv7. This allows
usage of FP HW, but implies soft-floating point ABI.
Issue #4421
According to C++11 reference:
"If the strictest (largest) alignas on a declaration is weaker than
the alignment it would have without any alignas specifiers (that is,
weaker than its natural alignment or weaker than alignas on another
declaration of the same object or type), the program is ill-formed:"
https://en.cppreference.com/w/cpp/language/alignas
The code requests 4 byte alignment for Genode::Arm_cpu::Context.
The Context structure inherits Genode::Arm_cpu::Fpu_context which
has minimum alignment requirement of 8 bytes, due to uint64_t d0_d31
member. This makes the 4 byte value in Context's alignas specifier
invalid (smaller than allowed minimum).
Similar situation takes place in Arm_64 case. The claimed minimum
alignment of Context is 8 bytes, but the fpu_state member imposes 16
bytes alignment (explicitly specified in Fpu_state declaration).
In both cases the code builds fine with GCC 8.3.0, but fails with
clang which claims that "requested alignment is less than minimum
alignment of X for type", where X is 8 on ARM and 16 on AArch64.

Issue #4421
This commit contains:
* Minimal Linux kernel target: pc_linux
* Library to generate a Linux build directory, config, generated headers
* API depot package
The actual work was provided by Josef Soentgen.

The official way to obtain DMA addresses for RAM dataspaces is
the RPC function 'Pd_session::dma_addr' now. User-level device drivers
should not call this function directly but use the 'Platform_session'
interface of the platform driver instead.
Fixes#2243
* Creates sessions to all supported services of the black hole component
* Test-drives the Event and Capture session with dummy input
* Adds the test to the default list of depot_autopilot.run
* Test-driving the Audio_in and Audio_out sessions is still missing and should
be added via a dedicated commit
Ref #4419
To make room for the re-newed usb_host_drv basing on Linux 5.14 and
the re-newed lx_kit/lx_emul we have to move the depot recipe and
consistently name the old drivers with a legacy_ prefix.
Ref genodelabs/genode#4416
The x86 platform driver uses a different API than the one for ARM for
which the lx_kit glue code was designed. Since the x86 platform driver
will eventually adopt a similar interface we implement a wrapper that
encapsulates the old interface.
Ref genodelabs/genode#4411
Until now, the lx_emul layer addressed a 5.11 Linux Kernel port,
now that we add new architectures it is better to update the default version
first. There are especially changes in the task_struct code,
and the signature of some functions in the paging subsystem changed.
Ref genodelabs/genode#4411
We use the architecture-specific setjmp/longjmp implementation without
modification in the newer lx_kit implementation as well. There is no
need for a duplication.
Ref genodelabs/genode#4411
In the error case of socket_fs_accept() the Unconfirmed utility was
incompletely applied with the result of executing the cleanup routines
in the wrong order.
Fixes#4417
This patch removes the implicit build of ld-$(KERNEL) by the generic
ld.mk file because the kernel-specific dynamic linker is unreachable
when building a regular binary archive.
Issue #4320
When 'KERNEL' is specified, let the generic (pseudo) target of
lib/mk/ld.mk trigger the build of the actual dynamic linker named after
the used kernel. This way, we become able to remove the magic
linker-build step from the boot-image stage of the run tool.
Issue #4320
This patch applies the existing "privatization" of transitive
shared-library dependencies from static lib dependencies to shared lib
dependencies. It thereby improves the consistency of binaries created in
a regular build directory with binaries created in depot archives.
Issue #4408
This patch makes nitpicker's "clicked" report useful for the detection
of clicks outside of any client. This is needed in situations where the
dialog should close when clicking outside its screen area. In the new
version, a click outside any client results in a report without a
'label' attribute. Furthermore, the report is augmented by the sequence
number of the click, which allows for freshness checks by the consumer of
the report (i.e., sculpt_manager).
Issue #4398
If the buffer contains padding at the end, the iteration must continue
in order to restart iteration from the start of the buffer.
genodelabs/genode#4244
The archive contents are equivalent except the creation date of the
top-level directory.
