21462cdbd2 base: Add const qualifiers to 'util/list.h'
This patch adds support for iterating through a const list. This allows
users of lists to be more rigid with regard to constness. Furthermore,
the patch adds the function 'List::insert_at' for inserting an element
at a specified position. By adding this function, we can remove code
duplication in nitpicker.

3e8e55ec16 CPU affinity configuration fixes
- if no affinity was set for a new thread before calling
  Cpu_session::start(), the CPU session's affinity gets set for this
  thread
- documentation fix: <affinity_space> -> <affinity-space>

4254cb04e1 Reduce IPC with timer service in timed semaphore
Instead of using msleep to sleep periodically, and then increase jiffies
counter in the alarm scheduler implementation of the timed semaphore
use the 'trigger_periodic' call introduced by the change of the timer session
interface into an asynchronous one. Thereby, we can reduce the necessary IPC
communication with the timer service effectively.

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.

e164671cd1 ahci_drv: basic support for exynos 5
This is a first version of the AHCI driver. It supports SATA HDDs
with UDMA-133 only, up to 6 Gbps and native command queueing.
The more blocks one transfers with one command, the higher is the
chance that the driver produces a fatal handshake error. Nevertheless
the driver is stable with one block per ATA command. Although NCQ is
used the driver doesn't queue multiple commands simultanously.

The driver was tested with a western digital HDD "WDC WD2500BEVS-08VAT1
13.01A13" (250 GB) with hw_arndale (run/ahci) and foc_arndale
(run/ahci, run/l4linux: dd). SSDs were not tested.

This patch implies that all Genode processes try to create an RM
session. So a route to the RM service must be present even for processes
that have only a single thread. Hence, the patch contains an update of
affected components.

cc5fddb0a2 Loader: Free entries of parent-service registry
The parent-service registry is populated on demand by the
'Loader::Child' whenever a prior unknown service is requested. Since the
number of parent services is limited, we expect the registry to settle
after a while. However, each loader session has a private instance of
a parent-service registry. So when creating and destroying loader
sessions, parent registries will be populated again and again. We
have to make sure to discard the entries along with the destruction
of a loader session to avoid the leakage of memory.
