Norman Feske 35723d813d core: evaluate CPU session affinity argument 2013-08-13 17:08:25 +02:00
Norman Feske 5fe29e8e4a Express affinities via Cartesian coordinates
This patch introduces new types for expressing CPU affinities. Instead
of dealing with physical CPU numbers, affinities are expressed as
rectangles in a grid of virtual CPU nodes. This clears the way to
conveniently assign sets of adjacent CPUs to subsystems, each of them
managing their respective viewport of the coordinate space.

By using 2D Cartesian coordinates, the locality of CPU nodes can be
modeled for different topologies such as SMP (simple Nx1 grid), grids of
NUMA nodes, or ring topologies.

Alexander Boettcher 4ae1faf14d base: add affinity support to pager construction
Propagating the affinity information is needed to allow for assigning

Christian Prochaska cb01f75a9d foc-arndale: use same context area location
Currently, on the Arndale platform, core uses a different thread context
area base address than the other tasks (0x20000000 vs. 0x40000000). This
is problematic, because core calculates the location of the UTCB area of a
new thread relatively to core's own thread context area base. So, the UTCB
area of non-core threads ends up in a virtual address range which is
outside of the task's thread context area and not marked as used in the
task's RM session.

With this patch, the same thread context area base address gets used in
core and in the other tasks.

Fixes #779.

Added spec file for ARM-VFPv3 floating-point unit. This shadows
'base/include/arm/' with 'base/include/arm/vfp' and enables a 'memcpy_cpu'
version that mainly uses the FPU. Enabled VFP support for 'foc_arndale'.

Alexander Boettcher e5eeda2ec9 run: support TFTP servers using absolute paths
TFTP server requiring absolute directory names are supported (better) -
specify in RUN_OPT "--tftp-absolute" to create Pulsar config with absolute
path names for PXE boot.

Additional a symbolic link is created from the build directory to
"$PXE_TFTP_DIR_BASE$PXE_TFTP_DIR_OFFSET" automatically. This eases the use
together with autopilot for x86.

Stefan Kalkowski 074e522990 base-foc: introduce state in platform thread
When destroying a thread, which was not bound to a protection domain via kernel
primitives beforehand, it is critical to change the pager and exregs the thread
in the destruction process. Therefore, this commit introduces two thread states:
DEAD and RUNNING. On the basis of the thread state, we can decide whether to
reset the thread before destroying it, or not.

Norman Feske 297538678e foc: Create thread at core at construction time
Originally, a thread was created at core not before calling the 'start'
function. In order to configure the thread affinity before starting the
thread, we have to make the thread known at core right at construction
time. This patch moves the needed thread-creation sequence from the
'start' function to the '_init_platform_thread' function.

Sebastian Sumpf 3ae2c1712e base-foc: Do not touch memory during map operation
Don't do anything in Mapping::prepare_map_operation.  At this point and in the
current implementation, the memory has been mapped and cleared already. Touching
the memory may only pollute the cache causing data corruption in DMA memory.

Norman Feske 21de42c45d core: Introduce 'Address_space' interface
The new core-internal 'Address_space' interface enables cores RM service
to flush mappings of a PD in which a given 'Rm_client' thread resides.
Prior this patch, each platform invented their own way to flush mappings
in the respective 'rm_session_support.cc' implementation. However, those
implementations used to deal poorly with some corner cases. In
particular, if a PD session was destroyed prior a RM session, the RM
session would try to use no longer existing PD session. The new
'Address_space' uses the just added weak-pointer mechanism to deal with
this issue.

Furthermore, the generic 'Rm_session_component::detach' function has
been improved to avoid duplicated unmap operations for platforms that
implement the 'Address_space' interface. Therefore, it is related to
issue #595. Right now, this is OKL4 only, but other platforms will follow.

Christian Prochaska a99193ad90 Rework the internal lock interface
With this patch, the 'futex' syscall gets used for blocking and unblocking
of threads in the Linux-specific lock implementation.

The 'Native_thread_id' type, which was previously used in the
lock-internal 'Applicant' class to identify a thread to be woken up,
was not suitable anymore for implementing this change. With this patch,
the 'Thread_base*' type gets used instead, which also has the positive
effect of making the public 'cancelable_lock.h' header file
platform-independent.

Fixes #646.

Christian Prochaska 2664afbd7d Remove context area from physical RAM allocator
In base-fiasco, base-foc and base-pistachio, physical memory gets mapped
1:1 to core virtual memory. When the 'Ram_session_component' allocates
physical memory for a client, it zeroes out the corresponding area in
core's virtual address space and then maps the area to the client. If this
area overlaps with core's virtual thread context area (usually at
0x40000000-0x4fffffff), the stack of one or more core threads can get
overwritten.

To avoid this problem, with this patch, the thread context area gets
removed from the physical RAM allocator on these platforms.

Fixes #660.
