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.

4dfa7902db os: Input::Event:Seq_number event type
The new event type allows for the propagation of sequence numbers as a means to
validate the freshness of input handling. E.g., an menu-view-based application
can augment artificial sequence numbers to the stream of motion events supplied
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.

22cce07ec8 fs_log: remove blocking call of get_acked_packet
This patch replaces formerly blocking packet-stream operations by
the explicit use of 'wait_and_dispatch_io_signal' for blocking.
It also removes a misleading comment that promised a fire-and-forget
behavior whereas the implementation relied on blocking I/O anyway.

480c0a7dee base-fiasco: silence recv_and_wait error messages
Errors during IPC receive-and-wait can occur at the server side when
a client is killed. This condition is not an error from the server's
perspective. We used to print a message nevertheless, since the
condition is rather exceptional. However, when printed during the
test-sequence test, the messages interfere with the pattern matching of
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.

7aa9cf9b37 uplink_client_base: add handlers for zynq_nic_drv
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.

84f8305cdf usb_report_filter: use VFS instead of fs session
This patch replaces the direct use of a file-system session via the
'file_system/util.h' helpers by the VFS using the os/vfs.h API. This
makes the component more flexible while removing the dependence from
read and write utilities of file_system/util.h, which happen to rely on
the (now removed) blocking packet-stream semantics.

911ff31709 dde_rump: use Block::Connection::Job API
This patch replaces the direct interaction with the packet stream of
the block session by the use of the 'Block::Connection::Job' API,
removing the reliance on blocking packet-stream semantics.

Since I/O signals can now occur during 'Backend::submit', the patch
conditions the periodic calls of 'rump_sys_sync' by taking the backend
state into account.

This patch takes precautions against the use of blocking packet-stream
operations like 'submit_packet'.

longer implicitly handled. Hence, a call of submit_packet to a

b3e12dcece vfs_gpu: VFS plugin that handles GPU completions
When a <gpu> node is present in the VFS, the plugin opens a
Gpu::Connection for each open call to the 'gpu' node and installs a
completion signal handler. A read only to the fd returned only comes
back if a completion signal has been received between two read
transctions to the fd.

For now the Gpu::Connections can be retrieved by calling the
'vfs_gpu_connection(unsigned long id)' function. The id can be obtained
using 'stat' on the 'gpu' device and is located in the inode (st_ino)
field of the stat buffer.
