e07781dc1c base: destruct signal receiver platform specific 
This is made for future signal framework in base-hw
wich needs a platform specific hook in the signal-

f763e5ec2a Move main bootstrap to platform-specific object 
To prevent multiple execution of main-bootstrap, I moved the code to a
statically initialized object. The reason for this change is that
_main() is exeuted twice when starting dynamic binaries. Now, the object
is part of the base-common library which is linked with ld.lib.so.

bb00aebc9e hw & signal: consider initial SLAB blocks 
By now Signal_session_component has allocated initial SLAB
blocks in constructor, wich crashed with the root
components assumptions about the RAM quota needs of
session creation. Thus, if the background allocator was already
exhausted from component allocation the session was created
with broken initial SLAB blocks.

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.

4ae1faf14d base: add affinity support to pager construction 
Propagating the affinity information is needed to allow for assigning
a pager thread that is local to the CPU of the to-be-created thread.

6c7a25d08c base-hw: use generic signal_session/connection.h 
base-hw extended the signal quota in a specific connection
implementation, which just conceals other issues if quota upgrade is
triggered.

Fixes #410.

e717ad656f base-hw: preserve symbolic link bin/core 
In this case "mv A B" works slightly different than "cp A B; rm A" as
symbolic links come into play. The statements should copy the contents
of A into the symboliv link at B (preserving it as is) and remove A. The
mv would replace the link B by the binary A.

Fixes #805.
