a30c4281d2 genode_c_api: report usb config on demand
Do not only report devices, but the current configuration of the driver too,
as long as the `report` node in the configuration states it.

938ac716a8 genode_c_api: make usb devices report configurable
To stay consistent with the configuration of the legacy usb_host_drv
and other components as well, do not report USB devices by default,
but when the following XML node is set within the component's
configuration:

  <report devices="yes"/>

a04d0b9a0f usb_session: increase default ram quota
The new usb_host driver for PC by default needs more RAM quota in contrast
to the old one. To minor warnings and repeated attempts to open a USB
session from a client, this commit increases the default RAM quota by one
page.

3c07bf4e86 genode_c_api: support to handle empty usb session
Adds a function to the USB part of the Genode's C API, to enable
usb_host drivers to acknowledge USB request in client's packet buffer
although they are not assigned to an USB device. The requests are
marked with a "no device" error.

This commit fixes a regression originally solved in genodelabs/genode#4149

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`.

4769e05626 mk: abi does not depend shared-lib dependencies
This patch cuts the superfluous dependency of abi.so files from the
library dependencies of the corresponding lib.so file. ABIs depend
only on symbol files.

Prior this patch, the second step of the following sequence would
wrongly re-build the abi.so file.

  arm_v6$ make init
  arm_v6$ make init KERNEL=hw

As the KERNEL argument does not affect the ABI, the abi.so should
better not be created twice.

300cdc435d expanding_report: make expandable for XML node generation
'generate(Xml_node node)', as used by the Sculpt manager, calls this
function instead of the lambda version. The 'report' function of the
'Genode::Reporter' does not throw an exception in case there is not
enough backing storage for the 'generate' request. Therefore, we have to
check this condition in a loop and call '_increase_report_buffer' in
case size limits are reached.

bade0a85e7 base-hw: Implement CPU core identification for Cortex-A55.
According to ARM Cortex-A55 Core Technical Reference Manual r1p0 the
lowest 8 bits (Aff0) of MPIDR register represent thread IDs within a
multi-threaded core. The actual core identification bits are in Aff1.
This layout can be identified by checking the MT bit of MPIDR register.
Basically, if MT=1 core id is in Aff1, if MT=0 core id is in Aff0.

Without this change Genode will identify all CPU cores on A55 as primary
(0) core.

Its worth to mention that Cortex-A55 by itself is not a multi-threaded
CPU. Aff0 values are always expected to be 0 for pure A55 cores. A55
cores can however be paired with cores that are multi-threaded. To
support such big.LITTLE CPUs in Genode we'd probably need to add a
different mechanism for mapping MPIDR values to logical, contignous
core IDs which Genode expects.

58e0b24006 base: Ignore empty constructors array.
This does not affect default Genode builds as far as I can tell. There
is always at least one global static CTOR which seems to be coming from
one of the GCC runtime libs bundled in the toolchain. The problem became
visible for me only after I've replated GCC runtime with LLVM based
one. In such setup I often see binaries that do not have any static ctors.
Such binaries end up crashing Genode ld.lib.so.

Make sure the code does handle empty constructors array.

05e4993d2e gems: Avoid flexible array member in Cached_font.
Switch the code to 0 lengh array instead. The code in
Lru_cache::element_size calls sizeof on this structure. This works in
gcc, but fails when using clang. Even for GCC however the documentation
states:

  "Flexible array members have incomplete type, and so the sizeof operator
   may not be applied. As a quirk of the original implementation of
   zero-length arrays, sizeof evaluates to zero."

Basically its an implementation quirk that clang does not support. Both
GCC and clang do support zero sized arrays however so using them here
allows both compilers to process this code.

5e93a5806b base-hw: Use softfp ABI on virt_qemu ARMv7.
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.

4ae78639f5 base-hw: Fix invalid structure alignments.
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.

479f2e0d1f trace_logger: remove false warnings from the log
This patch eliminates warnings that occurred as side effect of using the

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.

8e9cabf819 sculpt_manager: touch-screen compatibility
This patch makes Sculpt's leitzentrale GUI able to respond to touch events. It
formerly assumed that click/clack events are always preceded by hover reports
that identify the clicked-on widgets. For touch events, however, the most
up-to-date hover information referred to the previous click because there is no
motion without touching. So the GUI tended to identify the wrong widgets as
click targets.

The patch solved this problem by testing the freshness of the hover information
at the time of the click. If the hover information is older than the click, the
action is deferred until up-to-date hover information becomes available.

to 'menu_view'. Menu view, in turn, can now report the latest received sequence
number in its hover reports, thereby enabling the application to robustly
correlate hover results with click positions.

perspective. We used to print a message nevertheless, since the
condition is rather exceptional. However, when printed during the

the depot_autopilot, flagging the successful test as an error.

df2e7fa842 vfs_block_file_system: remove Signal_receiver
The VFS block plugin used to depend on the blocking semantics of the
packet stream's 'get_acked_packet'. This patch replaces this dependency
by the use of 'wait_and_dispatch_one_io_signal'. However, in order to
implement this change, the custom instance of a 'Signal_receiver' had to
be removed as well.

To keep this patch as little invasive as possible, it does not touch the
direct use of the block session's packet stream, which should better be
replaced by the 'Block::Connection::Job' API.

The zynq_nic_drv follows a zero-copy approach and thus uses the packet
buffers as DMA memory. In order to know when the RX DMA memory can be used
for another packet, a custom ack_avail_handler is needed.
Similarly, packets received from the Uplink session are not copied to a
DMA buffer but to directly passed on as DMA memory. For this purpose,
a a custom packet_avail handler is needed.

ac691eb229 file_system/util.h: remove packet-stream helpers
The 'read' and 'write' utilities are from a time before the VFS API
as os/vfs.h was available. They rely on the (now removed) blocking
semantics of the packet-stream interface.

The only remaining legitimate use case of the direct interaction with
the file-system session without VFS is the back end of gcov, which needs
a way to exfiltrate the statistical data using a channel that is
independent from the libc or the VFS.
