Put the initialization of the cpu cores, setup of page-tables, enabling of
MMU and caches into a separate component that is only used to bootstrap
the kernel resp. core.
Ref #2092
Instead of implicitly asking for core's link address when linking
core within the run tool, deliver it explicitly to the build_core
routine. Thereby we gain the freedom to use the build_core tool for
different targets like core, and bootstrap.
Ref #2092
This hook allows the export of the allocator's state by a derrived
class. I.e., the final state of the allocator used for bootstrapping
core.
Ref #2092
This patch eliminates the need for a global allocator by passing the
parent-service registry as argument to the 'Slave::Policy' constructor.
Fixes#2269
The support has two parts. First, a VFS plugin now gets passed an
I/O-response handler callback on construction, which informs users of the
VFS that an I/O event occurred. This enables, for example, the libC to
check if blocking read can be completed. Further, the VFS file I/O
interface provides now functions for suspendable reads, i.e.,
queue_read() and complete_read().
Replacing the node lookup table with an Id_space removes the
limit on open handles per session and allows mutal associativity
between File_system handles and local VFS handles.
Fix#2221
The test now forks twice - the parent forks a child and the child itself
forks a grand child. Both, parent and child, wait for termination of
their forked process with waitpid(). Additionally, the run script now
checks for exit of the parent (not any noux process).
First, calls to manage and dissolve signal contexts now check if the
signal receiver was constructed. There is a small window during suspend
where it is destructed before reconstructed again.
Last, we ensure that processing of incoming signal was deblocked by the
suspend signal before entering the suspend operation. This way we ensure
already queued signal are handled.
The block file system wrongly modified the seek offset during a
read-modify-write operation that is required for sub-block-size
requests. This led to problems whenever such write requests spanned
multiple blocks and thereby were handled in multiple iterations.
Fixes#2262
