509e5aa776 platform(x86): report features via platform_info
Report via platform_info the capabilities of the kernel, e.g. ACPI and MSI.

With the commit the try-catch pattern on IRQ session creation by the platform
driver is avoided.

dc89ebf978 core: kernel-agnostic 'Mapping' type
This patch unifies the core-internal 'Mapping' type across all base
platforms.

As one minor downside on seL4, the diagnostic error messages when
observing faults other than page faults no longer print the faulting
thread and PD names.

6223ae4413 riscv: Interrupt controller support
- Enable the "platform-level interrupt controller" PLIC on base-hw

fa68325a57 base-hw: streamline extraction of depot archives
This patch simplifies the packaging of the base-hw kernel for a given
board, in particular when the board support is hosted as an external
repository such as genode-world. Regardless of where the board-support
is hosted, the content.mk file becomes as simple as:

  include $(GENODE_DIR)/repos/base-hw/recipes/src/base-hw_content.inc

The board name is automatically inferred from the path of the src
recipe. The architecture is determined from board/<name>/arch files,
following the pattern of the image_link_address. The attempt to build a
base-hw-<board> binary archive for the wrong architecture is now
gracefully handled by skipping all targets (using the REQUIRES
mechanism).

Besides the improved convenience, the patch results in depot archives
that are much closer tailored to the actual board by omitting files for
architectures that are not used by the board. E.g., the src/base-hw-pc
archive does not contain any ARM-related content.

The patch also restores the package builds for core/bootstrap object
files as a follow-up fix of "base: remove SPEC variables of boards",
which happened to left 'BOARD' undefined in the src archives.

c4cf9b6e6d base-hw: introduce board-property directories
This patch moves the bootstrap-link-address information from the

customize boot_dir/hw when hosting board-support in an external

8f6b934caa base-hw: Fully define _crt0_start_stack value on arm_64
The _crt0_start_stack label points to a memory location containing the
size of the bootstrap stack. On AArch64 this should be an 8 byte value,
but the code only only defines half of those using asm .long statement.
The other half is expected to be 0, which is true when using GNU as.
This is not the case when using clang's integrated as however. Since
_crt0_stack_size is defined inside .text section clang uses 0xd503201f
value (aarch64 nop instruction) to fill the extra 4 bytes.

Fix this minor incompatibility by explicitly defining both halfs of
this 8 byte quantity.

5db2971903 base-hw/arm_v7a: Mark r1 as out in Kernel::call64
In case of arm_v7a Kernel::call64 the syscall will use both r0 and r1 as
output registers. Unfortunately the inline asm does not reflect this and
only r0 is explicitly specified as output. GCC manages to produce output
which we'd like to see. Clang on the other hand takes adventage of the fact
r1 should not be touched by swi and produces fewer instructions which do
what the code describes, but not what we actually want.

Basically the code which we want and is generated by GCC is:
  svc     0
  mov     r2, r0
  mov     r0, r1
  mov     r1, r2
  bx      lr

Clang on the other hand generates correct assembly given the code, but
incorrect given what the function is supposed to do:
  svc     0
  mov     r1, r0
  mov     r0, #0
  bx      lr

Both GCC and clang generate the same, expected assembly output when r1
is marked as output register from the inline asm swi call.

a892018926 base-hw: Define Entry function as noreturn.

Instead of calling core to run/pause a VCPU, go directly to the kernel.

* read out I-, and D-cache line size at runtime and use the correct one
* remove 'update_data_region' call from unprivileged syscalls
* rename 'update_instr_region' syscall to 'cache_coherent_region' to
  reflect what it doing, namely make I-, and D-cache coherent
* restrict 'cache_coherent_region' syscall to one page at a time
* lookup the region given in a 'cache_coherent_region' syscall in the
  page-table of the PD to prevent machine exceptions in the kernel
* only clean D-cache lines, do not invalidate them when pages where
  added on Cortex-A8 and ARMv6 (MMU sees phys. memory here)
* remove unused code relicts of cache maintainance

In addition it introduces per architecture memory clearance functions
used by core, when preparing new dataspaces. Thereby, it optimizes:

* on ARMv7 using per-word assignments
* on ARMv8 using cacheline zeroing
* on x86_64 using 'rept stosq' assembler instruction

2cf4e5a6de hw: fix regression of smp kernel initialization
In commit "hw: improve cross-cpu synchronization" the implicit safe
initialization of the global kernel lock gets unsafe.
It is a static object, which is protected by the cxx library regarding
its initialization. But our cxx library uses a Genode::semaphore in
the contention case of object construction, which implicitly leads
to kernel syscalls for blocking the corresponding thread. This behaviour
is unacceptable for the kernel code.
Therefore, this fix guards the initialization of the kernel code with
a simple static boolean value explicitely.

5ed5fddb7c base/os: remove deprecated APIs
This commit removes APIs that were previously marked as deprecated. This
change has the following implications:

- The use of the global 'env()' accessor is not possible anymore.
- Boolean accessor methods are no longer prefixed with 'is_'. E.g.,
  instead of 'is_valid()', use 'valid()'.
- The last traces of 'Ram_session' are gone now. The 'Env::ram()'
  accessor returns the 'Ram_allocator' interface, which is a subset of
  the 'Pd_session' interface.
- All connection constructors need the 'Env' as argument.
- The 'Reporter' constructor needs an 'Env' argument now because the
  reporter creates a report connection.
- The old overload 'Child_policy::resolve_session_request' that returned
  a 'Service' does not exist anymore.
- The base/printf.h header has been removed, use base/log.h instead.
- The old notion of 'Signal_dispatcher' is gone. Use 'Signal_handler'.
- Transitional headers like os/server.h, cap_session/,
  volatile_object.h, os/attached*_dataspace.h, signal_rpc_dispatcher.h
  have been removed.
- The distinction between 'Thread_state' and 'Thread_state_base' does
  not exist anymore.
- The header cpu_thread/capability.h along with the type definition of
  'Cpu_thread_capability' has been removed. Use the type
  'Thread_capability' define in cpu_session/cpu_session.h instead.
- Several XML utilities (i.e., at os/include/decorator) could be removed
  because their functionality is nowadays covered by util/xml_node.h.
- The 'os/ram_session_guard.h' has been removed.
  Use 'Constrained_ram_allocator' provided by base/ram_allocator.h instead.

aa66b5d62f base: remove dependency from deprecated APIs
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.

The most prominent changes are:

- Removing the use of base/printf.h

- Removing of the log backend for printf. The 'Console' with the
  format-string parser is still there along with 'snprintf.h' because
  the latter is still used at a few places, most prominently the
  'Connection' classes.

- Removing the notion of a RAM session, which does not exist in
  Genode anymore. Still the types were preserved (by typedefs to
  PD session) to keep up compatibility. But this transition should
  come to an end now.

- Slight rennovation of core's tracing service, e.g., the use of an
  Attached_dataspace as the Argument_buffer.

- Reducing the reliance on global accessors like deprecated_env() or
  core_env(). Still there is a longish way to go to eliminate all such
  calls. A useful pattern (or at least a stop-gap solution) is to
  pass the 'Env' to the individual compilation units via init functions.

- Avoiding the use of the old 'Child_policy::resolve_session_request'
  interface that returned a 'Service' instead of a 'Route'.

2e1e7b8270 recipes/src/base-hw-muen: add static ACPI ROM
As we don't execute the acpi_drv on Muen, we have to supply a static
'acpi' info as boot module. This is normally done by the
base/run/platform.inc include. However, when using base-hw-muen kernel
from a depot archive - as done by modern run scripts like
depot_download.run - the platform.inc magic is not applied.

This patch enhances the src archive of base-hw-muen with a mechanism
that creates a pre-defined acpi info at the bin directory via an
artificial src/acpi/target.mk file. This way, the static acpi ROM ends
up as boot module when importing the base-hw-muen archive into a
run script.

6b289a1423 base/core: use references instead of pointers
This patch replaces the former prominent use of pointers by references
wherever feasible. This has the following benefits:

* The contract between caller and callee becomes more obvious. When
  passing a reference, the contract says that the argument cannot be
  a null pointer. The caller is responsible to ensure that. Therefore,
  the use of reference eliminates the need to add defensive null-pointer
  checks at the callee site, which sometimes merely exist to be on the
  safe side. The bottom line is that the code becomes easier to follow.

* Reference members must be initialized via an object initializer,
  which promotes a programming style that avoids intermediate object-
  construction states. Within core, there are still a few pointers
  as member variables left though. E.g., caused by the late association
  of 'Platform_thread' objects with their 'Platform_pd' objects.

* If no pointers are present as member variables, we don't need to
  manually provide declarations of a private copy constructor and
  an assignment operator to avoid -Weffc++ errors "class ... has
  pointer data members [-Werror=effc++]".

This patch also changes a few system bindings on NOVA and Fiasco.OC,
e.g., the return value of the global 'cap_map' accessor has become a
reference. Hence, the patch touches a few places outside of core.

bf62d6b896 Move timer from os to base repository
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.

Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.

Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.

8e13b376b0 hw: improve cross-cpu synchronization
This commit addresses several multiprocessing issues in base-hw:

* it reworks cross-cpu maintainance work for TLB invalidation by
  introducing a generic Inter_processor_work and removes the so
  called Cpu_domain_update
* thereby it solves the cross-cpu thread destruction, when the
  corresponding thread is active on another cpu (fix #3043)
* it adds the missing TLB shootdown for x86 (fix #3042)
* on ARM it removes the TLB shootdown via IPIs, because this
  is not needed on the multiprocessing ARM platforms we support
* it enables the per-cpu initialization of the kernel's cpu
  objects, which means those object initialization is executed
  by the proper cpu
* it rollbacks prior decision to make multiprocessing an aspect,
  but puts back certain 'smp' mechanisms (like cross-cpu lock)
  into the generic code base for simplicity reasons

fbe9d26c47 trace: initialize trace control in Thread::start
Previously, the trace control of a thread was initialized in its
constructor (which is generic for all components). This has the
disadvantage that the CPU-session-pointer member of the thread might not
be valid at this point. And it cannot be replaced by using the
"deprecated_env" CPU session neither as constructing the deprecated
environment in causes troubles in Core. But as the trace control
shouldn't be needed in Core anyway, the initialization can be moved to
the Thread::start implementation of non-core components. This code
already takes care of the CPU session pointer.

AVL trees can't be copied with the default copy constructor as the

violates the integrity of the corresponding tree. The copy constructor
of Avl_tree is used in some places but in those places it can be
replaced easily. So, this commit deletes the copy constructor of
Avl_node_base which makes Avl_node and Avl_tree non-copyable.

To adapt existing components to fix violations of the best practices
suggested by "Effective C++" as reported by the -Weffc++ compiler
argument. The changes follow the patterns outlined below:

* A class with virtual functions can no longer publicly inherit base
  classed without a vtable. The inherited object may either be moved
  to a member variable, or inherited privately. The latter would be
  used for classes that inherit 'List::Element' or 'Avl_node'. In order
  to enable the 'List' and 'Avl_tree' to access the meta data, the
  'List' must become a friend.

* Instead of adding a virtual destructor to abstract base classes,
  we inherit the new 'Interface' class, which contains a virtual
  destructor. This way, single-line abstract base classes can stay
  as compact as they are now. The 'Interface' utility resides in
  base/include/util/interface.h.

* With the new warnings enabled, all member variables must be explicitly
  initialized. Basic types may be initialized with '='. All other types
  are initialized with braces '{ ... }' or as class initializers. If
  basic types and non-basic types appear in a row, it is nice to only
  use the brace syntax (also for basic types) and align the braces.

* If a class contains pointers as members, it must now also provide a
  copy constructor and assignment operator. In the most cases, one
  would make them private, effectively disallowing the objects to be
  copied. Unfortunately, this warning cannot be fixed be inheriting
  our existing 'Noncopyable' class (the compiler fails to detect that
  the inheriting class cannot be copied and still gives the error).
  For now, we have to manually add declarations for both the copy
  constructor and assignment operator as private class members. Those
  declarations should be prepended with a comment like this:

        /*
         * Noncopyable
         */
        Thread(Thread const &);
        Thread &operator = (Thread const &);

  In the future, we should revisit these places and try to replace
  the pointers with references. In the presence of at least one
  reference member, the compiler would no longer implicitly generate
  a copy constructor. So we could remove the manual declaration.

d4a75ed9bb base-hw: move spec/zynq files to zynq_qemu
This is necessary because in contrast to the zynq boards (see specs in genode-world), only zynq_qemu uses UART_0.
These files should thus fall under the zynq_qemu spec.

d164cbac8c hw: do not change x86 paging attributes on fly
Instead of changing the attributes (e.g., Xd bit) of the top-level page-tables,
set them to allow everything. Only leafs of the paging hierarchy are set
according to the paging attributes given by core. Otherwise, top-level page-
table attributes are changed during lifetime, which requires a TLB flush
operation (not intended in the semantic of the kernel/core).
This led to problems when using the non-executable features introduced by
issue #1723 in the recent past.
