* Acknowledge receive of page-fault signal with ack_signal,
but restart thread execution separately
* use kill_signal_context when disolving a pager_object to prevent race
* Remove bureaucracy in form of Thread_event and Signal_ack_handler
* remove dead code in riscv, namely Thread_base definition
* translation_table_insertions function for ARM drops out,
which was overcautious
The sinfo function declared in sinfo_instance.h creates a static sinfo
object instance and returns a pointer to the caller.
- kernel timer and platform support to use sinfo() function to
instantiate sinfo object
- address and size of the base-hw RAM region via the sinfo API
- log_status() function in sinfo API
This commit adds rocket core on the Zynq FPGA support to base HW. It also takes
advantage of the new timer infrastructure introduced with the privileged 1.8 and
adds improved TLB flush support.
fixes#1880
Enhance the VM state, that can be accessed by a VMM, by a member
'unsigned irq_injection'. In Kernel::Vm::proceed check, whether
irq_injection is set. If so, check whether irq_injection is a
non-secure IRQ. If so, let the PIC raise this IRQ in the VM and reset
irq_injection.
Ref #1497
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'.
Fix#1673
