hw: remove core/ARM specific aspect perf_counter This aspect was always enabled when creating a build directory for hw, but is not enabled anymore due to recent build directory unifications. On the other hand it is needed for jitter entropy anyway. Ref #2190

Separation of thread operations from CPU session This patch moves the thread operations from the 'Cpu_session' to the 'Cpu_thread' interface. A noteworthy semantic change is the meaning of the former 'exception_handler' function, which used to define both, the default exception handler or a thread-specific signal handler. Now, the 'Cpu_session::exception_sigh' function defines the CPU-session-wide default handler whereas the 'Cpu_thread::exception_sigh' function defines the thread-specific one. To retain the ability to create 'Child' objects without invoking a capability, the child's initial thread must be created outside the 'Child::Process'. It is now represented by the 'Child::Initial_thread', which is passed as argument to the 'Child' constructor. Fixes #1939

Consolidate RM service into PD session This patch integrates three region maps into each PD session to reduce the session overhead and to simplify the PD creation procedure. Please refer to the issue cited below for an elaborative discussion. Note the API change: With this patch, the semantics of core's RM service have changed. Now, the service is merely a tool for creating and destroying managed dataspaces, which are rarely needed. Regular components no longer need a RM session. For this reason, the corresponding argument for the 'Process' and 'Child' constructors has been removed. The former interface of the 'Rm_session' is not named 'Region_map'. As a minor refinement, the 'Fault_type' enum values are now part of the 'Region_map::State' struct. Issue #1938

Integrate CAP session into PD session This patch integrates the functionality of the former CAP session into the PD session and unifies the approch of supplementing the generic PD session with kernel-specific functionality. The latter is achieved by the new 'Native_pd' interface. The kernel-specific interface can be obtained via the Pd_session::native_pd accessor function. The kernel-specific interfaces are named Nova_native_pd, Foc_native_pd, and Linux_native_pd. The latter change allowed for to deduplication of the pd_session_component code among the various base platforms. To retain API compatibility, we keep the 'Cap_session' and 'Cap_connection' around. But those classes have become mere wrappers around the PD session interface. Issue #1841

hw: fix capability accounting of kernel/core The recently implemented capability resource trading scheme unfortunately broke the automated capability memory upgrade mechanism needed by base-hw kernel/core. This commit splits the capability memory upgrade mechanism from the PD session ram_quota upgrade, and moves that functionality into a separate Pd_session::Native_pd interface. Ref #2398

base-hw: introduce Kernel::Main class 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. Ref #4217

Introduce 'spec' subdirectories to outline aspects Instead of holding SPEC-variable dependent files and directories inline within the repository structure, move them into 'spec' subdirectories at the corresponding levels, e.g.: repos/base/include/spec repos/base/mk/spec repos/base/lib/mk/spec repos/base/src/core/spec ... Moreover, this commit removes the 'platform' directories. That term was used in an overloaded sense. All SPEC-relative 'platform' directories are now named 'spec'. Other files, like for instance those related to the kernel/architecture specific startup library, where moved from 'platform' directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
