Before, some object API XML files conflicted when the include,
arch_include, and sel4_arch_include directories were combined:
- include/interfaces/sel4.xml
- arch_include/*/interfaces/sel4arch.xml
- sel4_arch_include/*/interfaces/sel4arch.xml
This commit renames them to:
- include/interfaces/object-api.xml
- arch_include/*/interfaces/object-api-arch.xml
- sel4_arch_include/*/interfaces/object-api-sel4-arch.xml
Now, when the include, arch_include, and sel4_arch_include directories
are combined, we are left with:
- interfaces/object-api.xml
- interfaces/object-api-arch.xml
- interfaces/object-api-sel4-arch.xml

Guard the new implementation of 64-bit x86 guests behind a config
option. This is done so that existing projects that use x86_64 hosts
with ia32-bit guests can continue to be supported until either the old
feature is preferred to be deprecated, or support can be added to
support both simmultaneously.

This commit combines a number of smaller commits which do the following:
* Enter IA-32e mode when running a 64-bit host
* Handle additional general purpose registers in 64-bit mode
* Handle 64-bit specific MSR events
* Properly save and restore FS, GS, and Shadow GS registers

In x86, EPT and normal mappings have different cache attributes. This
commit adds an enum for the EPT attributes.

Today the file autoconf.h is created by the CMake build system and thus
HAVE_AUTOCONF is always defined. Time to get rid of some legacy by
removing the check if HAVE_AUTOCONF is set.

All the kernel header files now use pargma once rather than the ifndef,
as the pre-processed C files do not change while header files
are protected with pargma once. This will also solve any naming issues
caused by ifndef.
This commit also converts our own copyright headers to directly use
SPDX, but leaves all other copyright header intact, only adding the
SPDX ident. As far as possible this commit also merges multiple
Data61 copyright statements/headers into one for consistency.
- Remove Remap function from seL4 API for arm, x86, riscv and the
respective invocation implementation.
- Update Map as replacement for Remap
- Update manual
This allows a change of rights if the frame being mapped is already
mapped in at the given vaddr. To map a page to a different address,
unmap it first.

This removes the assumption that each platform sotres the IPC buffer
address in a platform-specific register. The IPC buffer address is
instead stored in a thread-local variable in libsel4 which must be
initialised by the runtime.
Prior to this change, seL4_MappingFailedLookupLevel() would retrun '22'
after any failed EPT mapping operation. This change fixes this to return
the correct amount of unresolved bits in the address.
This change updates the vspace chapter to separate the high-level concept of a VSpace from the
architectually defined objects. It also updates the various names for the vspace parameter to all be
vspace.
- increases the maintainability of the docs
- move descriptions of methods to the API reference
- remove hardcoded invocations in manual
This commit removes the content completely from vspace.tex, as it is out of date and needs
restructuring. The next commit does the restructuring.
Introduced a new Doxygen XML tag '<docref>'. The intention of
this tag is to indicate a section of text in the Doxygen XML that
will contain a reference to another section in the Manual e.g.
"See \autoref<sec:x>". As other generation formats aren't aware of
other chapters/sections in the manual, the <docref> encapsulation
allows it to omit the text from the output. The Latex generator
has been modified to continue parsing the 'docref' contents.
Changes the way IO ports work such that instead of 'minting' IO port caps down into new
IO port caps with smaller ranges new IO port ranges must be allocated centrally from
an IO port control cap. This mechanism acts in a very similar fashion as IRQ handler/control
capabilities and ensures that allocated IO ports do not overlap. Disallowing overlapping
IO ports is necessary to ensure the CDT remains valid as capabilities are deleted.
The GetStatusBits invocation is only implemented on ia32. Adding the condition to the
XML list prevents the invocation from being in the list of invocations on x86_64, when
it has no implementation.
Using the bitfield generator to treat guards and badges as a union type can be convenient,
but it requires reserving a bit in the data for the bitfield run time type information.
This type information is not needed by the kernel as it knows implicitly whether the passed
data is a badge or a guard based on the kind of cap being operated on. However, with the
type information present we cannot pass a word sized piece of data to the kernel.
The solution here is to go back to using a plain seL4_Word as the type for invocations
that want a capdata and let the user either construct a badge as a plain word, or use
the seL4_CNode_CapData bitfield for constructing a guard, although they have to manually extract
the word representation out of it.
This provides documentation for kernel design of the x86 virtualisation, the additional
syscall and object invocations. The ARM design is not fully expanded.
Fixes an inconsistency between manual_label for the x86 AsidPool_Assign invocation
and its reference in the manual. This makes the x86 align with the ARM name.
