Norman Feske dc39a8db62 base: introduce Allocator::try_alloc
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'.

README core: add information about infos provided by core 2017-06-29 11:59:52 +02:00

This is generic part of the Genode implementation. It consists of two parts:

:_Core_: is the ultimate root of the Genode application tree
  and provides abstractions for the lowest-level hardware resources
  such as RAM, ROM, CPU, and generic device access. All generic parts of Core
  can be found here - for system-specific implementations refer to the
  appropriate 'base-<system>' directory.

:_Base libraries and protocols_: that are used by each Genode component
  to interact with other components. This is the glue that holds everything
  together.

_Core_ may export information about the hardware platform by an ROM
called 'platform_info'. Depending on the platform, e.g. ARM or x86 or riscv,
and depending on the boot mode and boot loader and kernel, some nodes may not
be populated.

!<platform_info>
! <acpi revision="2" rsdt="0x1fe93074" xsdt="0x1fe930e8"/>
! <boot>
!   <framebuffer phys="0x7300000" width="1024" height="768" bpp="32"/>
! </boot>
!</platform_info>

If the ACPI RSDT and XSDT physical pointer is reported by the used kernel
and/or bootloader, _Core_ may provide this information by the ROM.

If the graphic device is initialised and can be directly used by a framebuffer
driver, _Core_ may provide the physical pointer to the framebuffer, the
resolution and color depth in bits.
