Christian Helmuth cf358b5db1 Revert "foc: relax parsing of boot process termination"
This reverts commit a9a6e8df89.

Setting correct UART parameters in U-Boot also fixes the issue and
reenables us to observe L4 bootstrapper startup.

already had it).

Stefan Kalkowski a9a6e8df89 foc: relax parsing of boot process termination
Until now, the successful termination of the boot process was recognized
when 'expect' saw the first L4 bootstrapper output on serial line. On sytems
with initially shaky serial connection like Versatile Express, where the serial
line baudrate changes with the bootstrapper initialization, the first expected
line might be missing. Therefore, change the expected line to the first
Fiasco.OC kernel output.

Stefan Kalkowski 726c32e5f6 run: relax IP power plug recognition + serial EOF
* To communicate with IP power plug devices from Koukaam, to remote
  control power supply of test boards, don't parse minor versions, but
  support different IP power plugs
* TCL's expect may report an EOF when reading from the spawned serial
  terminal, especially when using 'socat' to stream serial over TCP/IP,
  although the spawned child is still running and delivering content.
  This problem is clearly not dependent on the characters send, but
  possibly due to strange pipe signals. When piping the serial output
  through 'tr' the problem vanishs.

Alexander Boettcher 9c0ced0a85 ldso: add __L4_ThreadSwitch to ldso symbol.map
This wasn't necessary before because we built an l4 library for
Pistachio and linked it against each application. With the new linker,
we compile the required files from within Genode and create a syscall
library that is only linked to ldso. If a program uses system calls
directly, for example, DDE kit's spinlock implementation, the required
symbols must be made globally accessible.

On the Versatile Express Cortex A9x4 platform the first memory region

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.

Sebastian Sumpf 038a7999bf ldso: Disallow recursive initialization
Do not support the global construction from of objects from within a global

from a global constructor. The construction will be post-boned until the current
constructor has finished.

Martin Stein 09e6c3457f hw_arndale: consider timer resets
On Arndale, the kernel timer resets to the initial value of the last
count-down and continues as soon as it reaches zero. We must check this
via the interrupt status when we read out the timer value and in case
return 0 instead of the real value.

Martin Stein b8ba3a7a22 hw: rename Kernel::Processor Kernel::Cpu
Kernel::Processor was a confusing remnant from the old scheme where we had a

Martin Stein 1b1fd1e1f9 hw: add and test totally sophisticated scheduler
The new scheduler serves the orthogonal requirements of both
high-throughput-oriented scheduling contexts (shortly called fill in the
scheduler) and low-latency-oriented scheduling contexts (shortly called
claim in the scheduler). Thus it knows two scheduling modes. Every claim
owns a CPU-time-quota expressed as percentage of a super period
(currently 1 second) and a priority that is absolute as long as the
claim has quota left for the current super period. At the end of a super
period the quota of all claims gets refreshed. During a super period,
the claim mode is dominant as long as any active claim has quota left.
Every time this isn't the case, the scheduler switches to scheduling of
fills. Fills are scheduled in a simple round robin with identical time
slices. Order and time-slices of the fill scheduling are not affected by
the super period. Now on thread creation, two arguments, priority and
quota are needed. If quota is 0, the new thread participates in CPU
scheduling with a fill only.  Otherwise he participates with both a
claim and a fill. This concept dovetails nicely with Genodes quota based
resource management as any process can grant subsets of its own
CPU-time and priorities to its child without knowing the global means of
CPU-time and priority.

The commit also adds a run script that enables an automated unit test of the
scheduler implementation.

of the list implementation.

Martin Stein 0ab5310b8a hw: enable kernel-internal tests via run tool
Kernel tests are done by replacing the implementation of an otherwise
empty function 'Kernel::test' that gets called once at the primary CPU
as soon as all kernel initialization is done. To achieve this, the test
binary that implements 'Kernel::test' must be linked against the core
lib and must then replace the core binary when composing the boot image.
The latter can be done conveniently in a run script by setting the new
argument 'core_type' of the function 'build_boot_image' to the falue
'test'. If no kernel test is needed the argument does not have to be
given - it is set to 'core' by default which results in a "normal"
Genode image.

Martin Stein b3bc9bd549 hw: idle execution context is no thread anymore
Previously, Idle_thread inherited from Thread which caused an extra
processor_pool.h and processor_pool.cc and also made class models for
processor and scheduling more complex. However, this inheritance makes
not much sense anyway as an idle context doesn't trigger most of the code
in Thread.

Martin Stein ec6c19a487 base: memory barriers in lock implementations
The memory barrier prevents the compiler from changing the program order
of memory accesses in such a way that accesses to the guarded resource
get outside the guarded stage. As cmpxchg() defines the start of the
guarded stage it also represents an effective memory barrier.

On x86, the architecture ensures to not reorder writes with older reads,
writes to memory with other writes (except in cases that are not
relevant for our locks), or read/write instructions with I/O
instructions, locked instructions, and serializing instructions.

However on ARM, the architectural memory model allows not only that
memory accesses take local effect in another order as their program
order but also that different observers (components that can access
memory like data-busses, TLBs and branch predictors) observe these
effects each in another order. Thus, a correct program order isn't
sufficient for a correct observation order. An additional architectural
preservation of the memory barrier is needed to achieve this.
