The namespace draws a clear line between the base library and the core
component.
It is declared at the new core-local header <types.h>, which is expected
to be included by all code of the core component. It is thereby a
natural place for kernel-agnostic general types like commonly used C++
utilities.
Fixes#4777
.SHELLFLAGS is extended by option pipefail to make pipes fail if any pipe
element fails. As .SHELLFLAGS is exported into sub-make instances it
must be unexported before calling third-party build systems recursively.
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.
To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.
Issue #4324
Introduce two new cache maintainance functions:
* cache_clean_invalidate_data
* cache_invalidate_data
used to flush or invalidate data-cache lines.
Both functions are typically empty, accept for the ARM architecture.
The commit provides implementations for the base-hw kernel, and Fiasco.OC.
Fixes#4207
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.
Issue #4016
Mapping normal memory bufferable restores support for unaligned reads on
DMA memory and prevents the following errors on imx6q_sabrelite.
KERNEL0: alignment error at 18003061 (PC: 0102e3f8, SP: 401ffb18, FSR: 90000001, PSR: 20000110)
Issue #4094
Issue #4157
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.
Issue #2243
Do not link base and core libraries into on large relocatable .o file,
which is linked later to core - causing long link times. Create an
independent library archive out of the base and core libraries that can
be linked faster.
