When there are too many PCI devices, the Expanding_reporter regenerates
the report. However, this doesn't reset the BDF counter used to iterate
over the devices. This results in starting the new report after the PCI
device that triggered the report buffer overflow. This commit fixes the
issue by putting the BDF counter initialization inside the lambda
function used to generate the report.

This patch fixes the corner case where an animated geometry changes its
destination mid-way while an animation is already in progress. The
'_trigger_animated_geometry' method used to back out early in this case,
which was intended as an optimization.

Ref #3291
With the new fact that plain time values are always 64 bit unsigned, the
timestamp type is never bigger than the plain time type. Therefore, a code path
in the curr_time interpolation that treated this condition is not neccessary
anymore.
Ref #3208
This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.
Fixes#3208
- Added 'io_buffer' attribute, default is 4M
- Added 'batch' attribute, specifying the number of jobs used
in parallel, default is 1 (sequential)
- Removed 'synchronous' attribute (use batch of 1 instead)
- Added 'copy' attribute (default "yes")
- Print number of signals ("triggered")
Issue #3283
This patch equips the 'Block::Connection' with a framework API for the
implementation of robust block-session clients that perform block I/O in
an asynchronous fashion.
An application-defined 'JOB' type, inherited from 'Connection::Job',
encapsulates the application's context information associated with a
block operation.
The lifecycle of the jobs is implemented by the 'Connection' and driven
by the application's invokation of 'Connection::update_jobs'. The
'update_jobs' mechanism takes three hook functions as arguments, which
implement the applications-defined policy for producing and consuming
data, and for the completion of jobs.
Issue #3283
As a preparatory step for introducing the new block-client API, we have
to turn the 'Block::Connection' into a class template. The template
argument will be used to tie an application-defined job type to the
block connection.
Issue #3283
Instead of using `cps` instruction, use an exception return
instruction to switch from `hyp` mode to `svc` mode.
Otherwise it causes unpredicted behaviour on ARM.
Fix#3284
This patch adds support for manually triggering the wakeup of the packet
sink by the source. This way, a packet source becomes able to marshal
batches of submissions or unmarshal batches of acknowledgements before
yielding the control over to the sink.

Issue #3111
remove_range may deny to the job on memory pressure or insane ranges,
which ends up in an endless loop when the Avl allocator is in destruction.
Since the Avl gets destructed, solely the memory free up is of importance,
not the correct range adjustments during remove_range.
Track the dataspaces used by attach and add handling of flushing VM space
when dataspace gets destroyed (not triggered via the vm_session interface).
Issue #3111
Handles corner case when addr + size becomes exactly 0. Before the commit
the function returned that sum is not part of the range, which is wrong.
Issue #3111
This patch removes the blocking Block::Session::sync RPC function and
adds the asynchronous operations SYNC and TRIM to the block session's
packet-stream interface.
Even though the patch adjusts all block components to the interface
change, the components keep the former blocking handling of sync
internally for now because of the design of the 'Block::Driver'
interface. This old interface is not worth changing. We should instead
migrate the block servers step by step to the new
'Block::Request_stream' API.
Fixes#3274
The new request tag allows a block-session client to uniquely correlate
acknowledgements with outstanding requests. Until now, this was possible
for read and write operations by taking the value of the request's
packet-stream offset. However, SYNC and TRIM requests do not carry any
packet-stream payload and thereby lack meaningful offset values. By
introducing the notion of a 'tag', we can support multiple outstanding
requests of any type and don't need to overload the meaning of the
'offset' value.
Issue #3274
This patch splits the 'Request' definition into smaller types that are
suitable for the client-side API too.
The new 'Operation' type comprises the block operation's type (opcode)
and the operation's arguments (block number, block count).
The former 'Request::operation_defined' is now 'Operation::valid'.
The 'Request' aggregates an 'Operation', which changes its object
layout.
Note that this commit relaxes the bit-precise definition of 'Request' to
facilitate the use of 'unsigned long' where appropriate, in particular
for the request tag (which should correspond to an 'Id_space::Id'). The
originally bit-precise definition was pursued to allow the sharing of
the 'Request' type between SPARK and C++ code. However, it turns out
that defining a native type in each language and a (set of) converting
constructors is a more natural approach.
Issue #3283
When receiving a terminal signal, the uart device model has to
take all characters out of the stream. Otherwise, characters
might never arrive at the VM. This was not recognized before,
because it was used with a quite slow UART only, which obviously
never achieved to send more characters at once.

A small terminal-client tool, which expects a specific line(-start),
and then sends a specified line to the other side. Optionally,
it prints all received lines to its LOG service.

This patch renames 'wakeup_client' to 'wakeup_client_if_needed' to
clarify that the method triggers signals only when needed, not on every
call.
The name 'wakeup_client' is prone to misguide users to call the function
conditionally as an optimization, thereby complicating the code, but to
no effect.
Fixes#3279
This patch replaces the formerly fixed 2 KiB data alignment within the
packet-stream buffer by a server-defined alignment. This has two
benefits.
First, when using block servers that provide small block sizes like 512
bytes, we avoid fragmenting the packet-stream buffer, which occurs when
aligning 512-byte requests at 2 KiB boundaries. This reduces meta data
costs for the packet-stream allocator and also allows fitting more
requests into the buffer.
Second, block drivers with alignment constraints dictated by the
hardware can now pass those constraints to the client, thereby easing
the use of zero-copy DMA directly into the packet stream.
The alignment is determined by the Block::Session_client at construction
time and applied by the Block::Session_client::alloc_packet method.
Block-session clients should always use this method, not the 'alloc_packet'
method of the packet stream (tx source) directly. The latter merely
applies a default alignment of 2 KiB.
At the server side, the alignment is automatically checked by
block/component.h (old API) and block/request_stream.h (new API).
Issue #3274
This patch modernizes the 'Block::Session::info' interface. Instead of
using out parameters, the 'init' RPC function returns a compound 'Info'
object now. The rather complicated 'Operations' struct is replaced by
a 'writeable' attribute in the 'Info' object.
Fixes#3275
Triggering of an invalidated signal seems to be no real exception,
but something that occurs regularily. Therefore, the kernel warning
is of no use to developers anymore.
Ref #3277
As far as possible remove usage of warning/error/log in the kernel,
otherwise the kernel context might try to take a lock hold by a core
thread, which results in a syscall to block.
Fix#3277
This patch removes the reliance of the extract tool from the libc's
behavior regarding the access of time and timing.
The extract tool is not expected to need time. However, unfortunately,
libarchive calls the 'time' function unconditionally. By adding a
dummy for 'time', we avoid bothering the libc, which would otherwise
need to obtain a time source.
Issue #3204
In the original version, I used 'number_of_bits' because Ada's 'Size
returns the size in bits, not bytes. But the values (for objects) are
always a multiple of 8. On the C++ side, performing size checks at the
granularity of bits is just awkward. The term 'object size' is more
natural.

By adding a wildcard at the beginning of (expected) error messages, the
test.run tool becomes able to match the lines (ignoring the characters
of the color escape sequence).
The 'aes_cbc_4k' library is simple wrapper around libsparkcrypto to
serve as a backend for storage encryption. It operates on data chunks of
4 KiB and uses AES-CBC while incorporating the block number and the
private key as salt values.

partitions, imx6), which failed with an error message that stated the
device is in use. Genode's libc/posix layer has no notion of mount
points.

The "nameserver" file cannot be opened through a VFS File_system client
if the plugin does not support opening the parent directory of
"/nameserver", which would be "/".
Ref #3269
Replace the I/O response handler that is passed to the VFS at
construction with an object that is dynamically attached to handles.
This object shall also accept read-ready notifications, and plugins are
encouraged to keep handles awaiting ready-ready notifications separate
from handles that await I/O progress.
Replace the use of handle lists in plugins with handle queues, this
makes the code easier to understand and the ordering of notifications to
the application more explicit.
These changes replace the use of the Post_signal_hook from all VFS
plugins, applications must assume that read-ready and I/O notifications
occur during I/O signal dispatch and use an Io_progress_handler at its
entrypoints to defer response until after signal dispatching.
