This patch adjusts the last remaining callers of 'core_env' and removes
the 'Core_env' interface.
- Core's RAM/cap accounts are now represented by 'Core_account'
implementing the 'Pd_account' interface.
- The former parts of 'Core_env' are now initialized in sequence
in 'bootstrap_component'.
- 'Core_child' has been moved to a header to reduce the code in
'main.cc' to a bare minimum. This as a preparation for the
plan of making 'main.cc' specific for each kernel.
Fixes#5408
This patch replaces the use of 'core_env()' in 'platform_services.cc' by
the function arguments 'core_ram', 'core_rm', and 'io_port_ranges'.
It also removes the 'Pd_session' argument from 'Io_port_root' and
'Irq_root' to avoid the reliance on the 'Pd_session' interface within
core,
Issue #5408
Replace the use of the global 'core_env()' accessor by the explicit
delegation of interfaces.
- For allocating UTCBs in base-hw, 'Platform_thread' requires
a way to allocate dataspaces ('Ram_allocator') accounted to the
corresponding CPU session, a way to locally map the allocated
dataspaces (core's 'Region_map'), and a way to determine the
physical address (via 'Rpc_entrypoint') used for the initial
UTCB mapping of main threads. Hence those interfaces must be
passed to 'Platform_thread'.
- NOVA's pager code needs to look up 'Cpu_thread_component'
objects using a map item as key. The lookup requires the
'Rpc_entrypoint' that hold the 'Cpu_thread_component' objects.
To make this 'Rpc_entrypoint' available, this patch adds
the 'init_page_fault_handing' function.
- The 'Region_map_mmap' for Linux requires a way to look up
'Linux_dataspace' objects for given dataspace capabilities.
This lookup requires the 'Rpc_entrypoint' holding the dataspaces,
which is now passed to 'platform.cc' via the new Linux-specific
'Core_region_map::init' function.
Issue #5408
`Vm_session_component::create_vcpu()` is present across all supported
kernels, yet until now it was not part of the `Vm_session` interface.
Add the method to the `Vm_session` interface. This unifies calls in the
base library and is the basis to remove the need for a common base class
for separate `Vm_session` implementations for SVM and VMX on x86_64.

- touch all memory before time measurements, to reduce lazy paging jitter
- diff of 100us between 2 memset runs are now considered a failure (before 10us)
- add refrence measurements of same region size which is not write-combined
- make the output easier parse able of write-combined test
Fixes#5342
Add extended FPU state detection and handling (via xsave and friends) to the
kernel, which has to store/load more FPU state (~512 -> 2k++) during context
switching of threads. Additional the referenced nova branch contains various
optimization during VM destruction and cross core IPC resource caching.
This FPU work is based upon upstream NOVA kernel and Hedron commits.

Turn some of the current assertions into warnings/error messages and
continue boot. Print the messages as soon as core_log is initialized,
so that on live/release systems (Sculpt OS) it may be inspected later on.

The code to group together SMT threads of one CPU and to move P-Core to
the beginning of Genode's affinity-space, did not consider to run on
SOCs with only E-Core CPUs.
Re-structure the code to support e-Core only SOCs.
Additionally, provide a fallback mapping in case of CPU id reordering problems.
Track faulty re-mapping and delay the reporting until core_log is initialized,
so that the warnings is visible to consumers, e.g. on Sculpt OS.

This patch tightens the coupling of the 'Platform_thread' objects
with their corresponding 'Platform_pd' objects by specifying the
'Platform_pd' as constructor argument, keeping the relationship
as a reference (instead of a pointer), and constraining the
lifetime of 'Platform_pd' objects to the lifetime of the PD.
It thereby clears the way to simplify the thread creation since all
PD-related information (like quota budgets) are now known at the
construction time of the 'Platform_thread'.
The return value of 'Platform_thread::start' has been removed because it
is not evaluated by 'Cpu_thread_component'.

- Remove exceptions
- Use 'Attr' struct for attach arguments
- Let 'attach' return 'Range' instead of 'Local_addr'
- Renamed 'Region_map::State' to 'Region_map::Fault'

The 'Thread_creation_failed' error is now reflected as
'Thread::Start_result' return value. This change also removes the
use of 'Invalid_thread' within core as this exception is an alias
of Cpu_session::Thread_creation_failed.
Issue #5245
This patch removes the exception formerly thrown by 'Cpu_thread::state'
and turns the 'Thread_state' structure into a plain compound type w/o a
constructor.

This patch replaces exceptions of the PD session RPC interface with
result types.
The change of the quota-transfer RPC functions required the adaptation
of base/quota_transfer.h and base/child.h.
The 'alloc_signal_source' method has been renamed to 'signal_source'
to avoid an exceedingly long name of the corresponding result type.
The Pd_session::map function takes a 'Virt_range' instead of basic-type
arguments.
The 'Signal_source_capability' alias for 'Capability<Signal_source>' has
been removed.
Issue #5245
Based on not emulated and therby wrong values, acpica calculates a
physical address which points to somewhere. Remove this hack from core and
try to emulate accesses inside acpica where necessary.

Issue #5234
Using a segment to reserve the AP (application processor) code page does not
work if the region overlaps with other non-memory types, e.g. bender checks
for the overlapping and denies to boot on such machines.
Without bender, the system boots up fine. So, partially remove the nova commit
"Add segment to reserve AP startup page" and instead apply the idea of
Cyberus's version. Place the AP boot code later during boot and save and
restore the memory before/after SMP bootstrap.
separately. The "iommu" option is now split up into "iommu_intel" and
"iommu_amd" and thereby can be disabled easily if required for one of the CPU
vendors.
Fixes#5206
- no need to explicitly switch off vga anymore
- use vPID for VMs which improves TLB usage if multiple vCPUs on same
pCPU is used, which happens to happen on Sculpt.
- support for mwait by nova kernel, which is off by default
