Stefan Kalkowski 87015df66c hw: change update_pd to invalidate_tlb 
In the past, the core-only privileged syscall `update_pd` was used only
to invalidate the TLB after removal of page-table entries.
By now, the whole TLB at least for one protection domain got invalidated,
but in preparation for optimization and upcomingARM v8 support,
it is necessary to deliver the virtual memory region that needs to get
invalidated. Moreover, the name of the call shall represent explicitely
that it is used to invalidate the TLB.

Sebastian Sumpf da17f2cbd3 hw: eager FPU switching for x86_64 
Since gcc 8.3.0 generates SSE instructions into kernel code, the
kernel itself may raise FPU exceptions and/or corrupt user level FPU
contexts thereby. Both things are not feasible, and therefore, lazy FPU
switching becomes a no go for base-hw because we cannot avoid FPU
instructions because of the entanglement of base-hw, base, and the tool
chain (libgcc_eh.a).

issue #3365
 2019-05-27 14:53:32 +02:00
Sebastian Sumpf f18285205c hw: enable FPU during CPU startup on x86 
Also disable TS (task switch) flag in cr0 during kernel initialization,
so FPU faults are not raised. This became necessary since GCC lately
aggressively generates FPU instructions at arbitrary places and also at
early kernel-bootstrapping stages.

Stefan Kalkowski a1e70b9ba4 kernel: differentiate board-specific components 
Components like kernel, core, and bootstrap that are built for a
specific board need to reside inside the same architectural dependent
build directory. For instance there are sel4, foc, and hw kernel builds
for imx6q_sabrelite and imx7d_sabre, which have to reside inside the same
arm_v7 build directory.
This commit names those components explicitely, and adapts the run-tool to it.

Stefan Kalkowski f074954d3d hw: use `eret` in `hyp` mode to switch mode 
Instead of using `cps` instruction, use an exception return
instruction to switch from `hyp` mode to `svc` mode.
Otherwise it causes unpredicted behaviour on ARM.

Track the dataspaces used by attach and add handling of flushing VM space
when dataspace gets destroyed (not triggered via the vm_session interface).

Stefan Kalkowski a147bdf406 hw: silent warning about unknown signal context 
Triggering of an invalidated signal seems to be no real exception,
but something that occurs regularily. Therefore, the kernel warning
is of no use to developers anymore.

Stefan Kalkowski 0ca199f89a hw: replace lock-safe log variants in kernel 
As far as possible remove usage of warning/error/log in the kernel,
otherwise the kernel context might try to take a lock hold by a core
thread, which results in a syscall to block.
