* Rename Kernel::Cpu_job to Kernel::Cpu_context (alias Kernel::Cpu::Context)
* State first Cpu affinity of Cpu::Context at construction time
* Move cpu affinity argument from kernel syscall create_thread to start_thread
* Ensure that Cpu pointer is always valid
Fixgenodelabs/genode#5319
The namespace draws a clear line between the base library and the core
component.
It is declared at the new core-local header <types.h>, which is expected
to be included by all code of the core component. It is thereby a
natural place for kernel-agnostic general types like commonly used C++
utilities.
Fixes#4777
On resume the CPU state must be re-initialized, since all CPUs have been
potentially off (depending on sleep form) and lost state. Handle the halt
and suspend state explicitly by an extra Job implementation which can be
executed without holding the global kernel lock.
Issue #4669
Let the kernel's driver for the global IRQ controller be a member of the one
Kernel::Main object instead of having it as static variables in the drivers for
the local IRQ controllers. Note that this commit spares out renaming 'Pic' to
'Local_interrupt_controller' which would be more sensible now with the new
'Global_interrupt_controller' class. Furthermore, on ARM boards the commit
doesn't move 'Distributer' stuff to the new global IRQ controller class as they
don't have real data members (only MMIO) and can be instanciated for each CPU
anew. However, the right way would be to instanciate them only once in Main as
well.
Ref #4217
It's sufficient to access the boot info only on kernel initialization time.
Therfore, it can remain completely hidden to the rest of the kernel inside
kernel/main.cc in the initialization function.
Ref #4217
This commit introduces the Kernel::Main class that replaces the former way of
initializing the kernel (former 'kernel_init' function) and calling the C++
kernel entry handler (former 'kernel' function). These two are now
'Main::initialize_and_handle_kernel_entry' and 'Main::handle_kernel_entry'.
Also reading the execution time of the idle threads was already moved to
'Main'. The one static Main instance is meant to successivly replace all the
global static objects of the base-hw kernel with data members of the Main
instance making the data model of the kernel much more comprehensible. The
instance and most of its interface are hidden in kernel/main.cc. There are only
rare cases where parts of the Main interface must be accessible from the
outside. This should be done in the most specific way possible (see main.h)
and, if possible, without handing out references to Main data members or the
Main instance itself.
