Stefan Kalkowski 2380fc442f ahci: avoid to reinstantiate backend driver
Instead of fixing the missing dynamic facilities of the AHCI driver
backends for x86 and Exynos5, just avoid to create/destroy the backend
for every new connection, but always use one and the same object.
The AHCI drivers need to be re-written anyway, see issue #1352 for instance,
we can make it more robust for the dynamic case then.

Martin Stein 9a4a0448be hw vea9x4: remove trustzone support
When building Genode for VEA9X4 as micro-hypervisor protected by the ARM
TrustZone hardware we ran into limitations regarding our basic daily
testing routines. The most significant is that, when speaking about RAM
partitioning, the only available options are to configure the whole SRAM
to be secure and the whole DDR-RAM to be non-secure or vice versa. The
SRAM however provides only 32 MB which isn't enough for both a
representative non-secure guest OS or a secure Genode that is still
capable of passing our basic tests. This initiated our decision to
remove the VEA9X4 TrustZone-support.

Martin Stein ba321c20d1 hw vea9x4: let userland timer SP804 0/1 be secure
Declaring the SP804 0/1 module and its interrupt to be non-secure prevents the
secure Genode from receiving the interrupt and hence the timer driver in the
secure Genode doesn't work.

Alexander Boettcher 8842ba2e1c nova: remove timer delay heuristic
The commit uses a fixed kernel branch (r8), which fixes a caching bug
observable in the Genode host. The quirk detecting the circumstance in the
timer service is obsolete now and is removed.

Martin Stein 8f9355b360 thread API & CPU session: accounting of CPU quota
In the init configuration one can configure the donation of CPU time via
'resource' tags that have the attribute 'name' set to "CPU" and the
attribute 'quantum' set to the percentage of CPU quota that init shall
donate. The pattern is the same as when donating RAM quota.

! <start name="test">
!   <resource name="CPU" quantum="75"/>
! </start>

This would cause init to try donating 75% of its CPU quota to the child
"test".  Init and core do not preserve CPU quota for their own
requirements by default as it is done with RAM quota.

The CPU quota that a process owns can be applied through the thread
constructor. The constructor has been enhanced by an argument that
indicates the percentage of the programs CPU quota that shall be granted
to the new thread. So 'Thread(33, "test")' would cause the backing CPU
session to try to grant 33% of the programs CPU quota to the thread
"test". By now, the CPU quota of a thread can't be altered after
construction. Constructing a thread with CPU quota 0 doesn't mean the
thread gets never scheduled but that the thread has no guaranty to receive
CPU time. Such threads have to live with excess CPU time.

Threads that already existed in the official repositories of Genode were
adapted in the way that they receive a quota of 0.

This commit also provides a run test 'cpu_quota' in base-hw (the only
kernel that applies the CPU-quota scheme currently). The test basically
runs three threads with different physical CPU quota. The threads simply
count for 30 seconds each and the test then checks wether the counter
values relate to the CPU-quota distribution.

Norman Feske e4c636b0a0 init: clamp priority values to valid range
This patch ensures that priority values passed as session arguments

to the subsystem. Thanks to Johannes Schlatow for reporting this issue.

Norman Feske 46968c0015 nitpicker: motion events for non-xray clients
When X-ray mode is active, nitpicker filters motion events that are not
referring to the currently focused domain. However, domains configured
as xray="no" (such as a panel) need to obtain motion events regardless
of the xray mode. This patch relaxes the motion-event filtering to
accommodate such clients.

Norman Feske 83705d3c78 nitpicker: fix input-mask offset calculation
The buffer offset was wrongly accounted for. The miscalculation went

Norman Feske 23c22f52b3 nitpicker: consider xray config in find_view
If a domain is configured as xray="no", we want to let the views of the
domain respond to input events like in flat mode, even if xray mode is
active. Normally, the input mask of views with an alpha channel is
disregarded in X-ray mode. However, for non-ray views, the input mask
should always be considered.

Christian Prochaska 81af714949 Input merger
This component merges the input events of multiple sources.

Example configuration:

<start name="input_merger">
	<resource name="RAM" quantum="1M" />
		<service name="Input" />
		<input label="ps2" />
		<input label="usb_hid" />
		<service name="Input">
			<if-arg key="label" value="ps2" /> <child name="ps2_drv" />
		<service name="Input">
			<if-arg key="label" value="usb_hid" /> <child name="usb_drv" />
		<any-service> <parent /> <any-child /> </any-service>

For each 'input' config node, the component opens an 'Input' session with the
configured label. This label is then evaluated by 'init' to route the session
request to a specific input source component.

Fixes #1259.

Christian Helmuth e9032904a3 Increase slab-block size in signal component
The backend allocator for the slab is a sliced heap, which hands out
allocations with page-size granularity (4096 bytes). Therefore, the
slab-block size should also be about a multiple of the page size minus
some bytes of overhead.

Additional adjustments:

- The slab-block size and the default quota-upgrade amount for SIGNAL
  sessions depends on the platform bit width now.
- The signal test also stresses the case of many managed context in one
  session including creation and destruction of the used signal receiver
  in repeated rounds.
