50d73e7890 block_session: extend interface with sync() call
To support components, which implement the block session's server side
rpc object, and which doesn't write data to their device backend immediately,
an additional synchronization call is needed. Thereby, clients like for
instance a file system can tell these components, when a synchronization is
required.

fde93c3284 init: don't call Rom_session::dataspace() twice
In general, requesting a dataspace from a server twice is no good
idea. The server might react in a unrecoverable fashion. E.g. the rom_fs
service always throws away the corresponding dataspace from the first call
of dataspace(), and constructs a new one.

27aeecf5d1 cli_monitor: add a 'gdb' command
This patch adds a 'gdb' command to 'cli_monitor', which makes it possible
to debug an application with GDB.

The command works similarly to the 'start' command, but instead of
starting the subsystem binary directly, an 'init' subsystem gets
started, which then starts 'terminal_crosslink', 'noux', GDB and
'gdb_monitor' (which starts the application binary as its target).

So, for the 'gdb' command to work, these additional components need to
be available, too. 'terminal_crosslink', 'noux', 'gdb_monitor' and the
file 'gdb_command_config' are expected to be ROM modules. The Noux GDB
client needs to get mounted at '/bin' in Noux and the target binaries need
to be available as ROM modules (loaded by 'gdb_monitor') and also mounted
at '/gdb' in Noux (loaded by the GDB client).
Additionally, the source code of the target application can be provided
at '/gdb/src/ in Noux. How the Noux mountings get established can
be configured in the 'gdb_command_config' file. The default configuration
in 'os/src/server/cli_monitor/gdb_command_config' mounts GDB from a tar
archive named 'gdb.tar', the GDB target binaries from a tar archive named
'gdb_target.tar' and the target source code from a tar archive named
'gdb_target-src.tar'.

The patch includes an 'expect' include file (ports/run/noux_gdb.inc)
which provides functions that help to create those tar files:

- 'create_gdb_tar' creates a tar archive for the 'gdb' client
- 'create_binary_tar' creates a tar archive for the target application
- 'create_source_tar' creates a tar archive for the source code of
  the target application
- 'create_binary_and_source_tars' is a convenience wrapper for the previous
  two functions

The patch also includes an example run script
(ports/run/noux_gdb_dynamic.run).

The 'gdb' command supports the following command line options:

- --ram: the initial RAM quota provided to the whole subsystem
         (including the GDB-related components)
- --ram-limit: limit for expanding RAM quota
- --gdb-ram-preserve: the RAM quota that 'gdb_monitor' ahould preserve
                      for itself

Fixes #928.

f82e1a7092 nitpicker: Late allocation of virtual framebuffer
This patch changes the interface of Nitpicker to support dynamically
dimensioned virtual frame buffers. This solves two problems:

First, it enables a client to create a connection to nitpicker without
donating much session quota in advance. The old interface required each
screen-size-dependent client to donate as much memory as needed to
allocate a screen-sized virtual framebuffer. For clients that are
interested int the screen size but cover just a small portion of the
screen (e.g., a banner, a menu, an applet that sits in the screen
corner), this overprovisioning is painful. The new interface allows such
clients to upgrade the session quota for an existing session as needed.

Second, because each nitpicker session used to have a virtual frame
buffer with a fixed size over the lifetime of the session, a client that
wanted to implement a variable-sized window had to either vastly
overprovide resources (by opening a session as large as the screen just
in order to be prepared for the worst case of a maximized window), or it
had to replace the session by a new one (thereby discarding the stacking
order of the old views) each time the window changes its dimensions. The
new interface accommodates such clients much better.

a903049a1a cli_monitor: Resource-balancing support
This patch introduces new commands for dynamically balancing RAM between
subsystems. The 'status' command prints a table with the RAM status of
each subsystem. The 'ram' command changes the quota or a quota limit of
a given subsystem. The quota limit can be defined to allow the on-demand
expansion of the quota. Finally, the 'yield' command can be used to
instruct a subsystem to yield a specified amount of resources.

For trying out the new commands, a so-called 'ram_eater' example has
been added to the 'terminal_mux.run' scenario. This program simulates a
subsystem with a growing demand for resources, yet with the capability
to yield resources when instructed by the parent (i.e., cli_monitor).

Besides implementing the new features, the patch splits the
implementation of 'cli_monitor' into multiple files.

Norman Feske
6575856624 os: Split Session_label from Session_policy
By splitting Session_policy into two classes, we make it more flexible.
Originally, the constructor accepted solely an args string, which made it
unusable for situations where we already have extracted the session
label (e.g., stored in the session meta data of a server). Now, the
extraction of the label from the args string is performed by the new
Session_label class instead, which, in turn, can be passed to the
constructor of Session_policy.

This change causes a minor API change. The following code

  Session_policy policy(session_args);

Must be turned into

  Session_label  label(session_args);
  Session_policy policy(label);

35a96e1101 acpi: parse RMRR structures and print DMA regions
The regions reported by the RMRR structure are used by legacy devices for DMA
requests. Theses would need to be added to the device_pd to avoid DMAR faults
when used in legacy mode.

For now parse and print them, so that one has a clue about why we get DMAR
faults.

5ec07614e8 init: Read affinity assignments from config
The assignment of affinities consists of two parts, the definition
of the affinity space dimensions as used for the init process, and
the association sub systems with affinity locations (relative to the
affinity space). The affinity space is configured as a sub node of the
config node. For example, the following declaration describes an
affinity space of 4x2:

<config>
  ...
  <affinity_space width="4" height="2" />
  ...
</config>

Subsystems can be constrained to parts of the affinity space using
the '<affinity>' sub node of a '<start>' entry:

<config>
  ...
  <start name="loader">
    <affinity xpos="0" ypos="1" width="2" height="1" />
    ...
  </start>
  ...
</config>

6d837c9e26 Attach affinity information to session requests
This patch extends the 'Parent::session()' and 'Root::session()'
functions with an additional 'affinity' parameter, which is inteded to
express the preferred affinity of the new session. For CPU sessions
provided by core, the values will be used to select the set of CPUs
assigned to the CPU session. For other services, the session affinity
information can be utilized to optimize the locality of the server
thread with the client. For example, to enable the IRQ session to route
an IRQ to the CPU core on which the corresponding device driver (the IRQ
client) is running.

3fb7e74287 ahci & exynos5: avoid large DMA buf in AHCI bench
Normally this bench has read all data to one large buffer and
than written it back to the drive but for SATA 3 (6 Gbps) benchmarks
we would need a buffer of approximately 1.2 GB to do it this way
and reach 2 seconds bench time. Thus we use a buffer of SATA request size
and override it with every request.

ada408d2f7 ahci & exynos5: enable HDDs like Seagate Barracuda
Initialize and limit port speed to 3 Gbps in general because the Seagate
Barracuda 1TB throws much errors with 6 Gbps by now.

Try all port speeds from the highest to the lowest as long as debouncing fails
and try them all again in this order when falling back to slower debouncing.

Try to recover from all types of interface error.

When a port was recovered from an error during a NCQ command
get the last LBA that was accessed successfully and continue command from
this point.

Use a platform driver through the 'Regulator' service to do CMU and PMU config.

Switch off verbosity by default.

for more flexible generalization between e.g. source or, sink
