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.

To enable the use of uncached DMA buffers as RX and TX communication
buffers in between driver (service) and client, introduce a cache
attribute in the constructor of Nic::Session_component
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.
