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.
