* Adds object and cap definitions for VT-x structures (VCPU and EPT).
* Extends the asid_map implementation to support ASIDs in the EPT
* Adds size definitions for VCPU and EPT objects
CONFIG_LIB_SEL4_PUBLIC_SYMBOLS=y will disable inlining for external
interfaces (except deprecated functions), thereby providing public
symbols for easy linkage with other languages.

arm: Use new cap rights structures in iospace
libsel4: Correct VGIC and VCPU fault types
libsel4: Correct deprecated macro for in unknown syscall
* commit '2e30ac481f212b3490fde8dbd13f496a50d70f49':
libsel4: Add remaining combinations of cap rights
libsel4: Removed stray semicolon from shared_types
This also moves the description of TCBSetEPTRoot from the general object
invocation xml file to the x86-specific one to prevent the need for
documentation-generating scripts to distinguish between VTX (ie. x86)
invocations, and truly architecture independent invocations.
JIRA: SELFOUR-606
The motivation for this change is the fact that the types of `true` and
`false` are different between userland and the kernel. This was forcing
code including shared_types.h to first include the appropriate header
defining `true` and `false`. This change prevents this need.
This change
* changes seL4_CapRights from the kernel to be seL4_CapRights_t in
libsel4
* deprecates the duplicated seL4_CapRights in libsel4, which is
now the bitfield generated type seL4_CapRights_t.
* fixes all usages in kernel and libsel4
Impact: for verification, this will require the type to change name
from cap_rights to seL4_CapRights_t.
This is a breaking libsel4 API change, although most code uses
seL4_AllRights or similar constants, which will not break
at a source level as these constants have been updated.
This is a *breaking API change*
This commit:
* makes seL4_Fault_tag_t common between the kernel and libsel4
* deprecates the existing functions from sel4/messages.h includes
* introduces a new fault API in sel4/faults.h and
* sel4/sel4_arch/faults.h
* deprecates seL4_GetTag(), as the function did not work without
the user calling seL4_SetTag() first (seL4_MessageInfo is passed
in registers and not set in the IPC buffer)
* removes previously deprecated functions (deprecated prior to 3.0.0)
* updates the seL4 manual to reflect the changes
Prior to this commit faults were separate
per architecture. This commit extracts the common
fault types and introduces arch specific faults,
reducing code duplication across architectures.
This commit adds support for using the ThreadID registers of the ARM MPCore
platforms for storing the address of the IPC buffer instead of the globals
frame. The choice of using the user readable/writeable ThreadID register
is chosen, even though it means the user cannot use it for its own
purposes, as it leaves room in the future for doing TLS support in the
user read only register, where compilers expect it.
Removes the recycle operation and adds an operation
to cancel any badged sends on and endpoint. Calling
Revoke + CancelBadgedSend is equivalent to Recycle
on a badged endpoint
This reorders the bootinfo struct to place the untyped array as the
last element. Having the array at the end makes the layout of the
information in this struct easier to represent in other languages.
This change uses the seL4_MaxUntypedBits constant in decodeUntypedInvocation
when checking the size of the requested allocation. This constant
is also changed to be the correct value. The verification team suspects
this check is probably unnecessary, but have also resolved not to waste more
time investigating.
* commit 'be68b0c0bde5bfa439376fac4c8be255dacaa958':
libsel4: Allow invocations to not use IPC buffer
Retain in-register error descriptions when not using IPC buffer
- Fixes "lost" error descriptions when using *WithMRs system call
variants [1].
- Only stores real registers to IPC buffer if there's an error.
- If there's an error in a struct-returning function, return
early without setting any struct members.
- Passes the sabre/qemu test suite... with and without --buffer!
[1] https://sel4.systems/pipermail/devel/2016-October/001079.html
* Initialise the message variables (as per ia32 and x86_64)
* `libsel4` now builds when `syscall_stub_gen.py` is run without `--buffer`
* While simple things appear to work, `sel4test` with aarch32 in qemu is *not* happy:
```
Bootstrapping kernel
Warning: using printf before serial is set up. This only works as your
printf is backed by seL4_Debug_PutChar()
sel4utils_create_object_at_level@mapping.h:22 Should not be called
Ignoring call to sys_rt_sigprocmask
Ignoring call to sys_gettid
sys_tkill assuming self kill
```
The lowest syscall number is -8, which doesnt' fit in 3 bits -> change
to 4.
Also, we were storing the -ve number, which also doesn't fit into 3
bits -> invert it when we store it.
