Some session interfaces use session-local handles for referring to
server-side objects, e.g., a file-system session hands out file handles
to the client. The new 'Handle_registry' class template can be used to
associate numeric handles with objects on the server side and thereby
simplifies the implementation of such servers.
This patch enables the debugging on services that rely on dynamic
session upgrades. For example, nitpicker expects its clients to donate
RAM quota that matches the size of the virtual framebuffer, which might
change during the lifetime of a nitpicker session.
* repos/ports/include/vmm
- add support to specify cpu location during vCPU construction
* seoul
- update to latest seoul branch supporting smp
- adjust to vmm interface changes
- vCPUs will be put in a round robin fashion on the available host CPUs,
beginning with the next CPU after the default (boot) CPU
- number of vCPUs can be specified in run script
* virtualbox
- adjust to vmm interface changes
- uses still one vCPU, placed on default (boot) CPU

This reverts commit edc03489b3.
Since commit
"timer: nova specific version of the service"
a nova specific timer is used and this quirk is not necessary anymore.
Issue #1211
When a page fault cannot be resolved, the GDB monitor can get a hint about
which thread faulted by evaluating the thread state object returned by
'Cpu_session::state()'. Unfortunately, with the current implementation,
the signal which informs GDB monitor about the page fault is sent before
the thread state object of the faulted thread has been updated, so it
can happen that the faulted thread cannot be determined immediately
after receiving the signal.
With this commit, the thread state gets updated before the signal is sent.
At least on base-nova it can also happen that the thread state is not
accessible yet after receiving the page fault notification. For this
reason, GDB monitor needs to retry its query until the state is
accessible.
Fixes#1206.
The build config for core is now provided through libraries to enable
implicit config composition through specifiers and thereby avoid
consideration of inappropriate targets.
fix#1199
The count value can be used to batch timeouts. I.e., if a periodic
timeout triggered multiple times before the timer had a chance to
process them, the count corresponds to the number of passed periods.
A subject that inherits from Processor_client not necessarily has the need for
doing a processor-global TLB flush (e.g. VMs). At the other hand the Thread
class (as representation of the only source of TLB flushes) is already one of
the largest classes in base-hw because it provides all the syscall backends
and should therefore not accumulate other aspects without a functional reason.
Hence, I decided to move the aspect of synchronizing a TLB flush over all
processors to a dedicated class named Processor_domain_update.
Additionally a singleton of Processor_domain_update_list is used to enable
each processor to see all update-domain requests that are currently pending.
