Norman Feske 4b46abf813 base: rm first-class support for static binaries This patch removes the detection of statically linked executables from the base framework. It thereby fixes the corner cases encountered with Sculpt when obtaining the binaries of the runtime from the depot_rom service that is hosted within the runtime. Statically linked binaries and hybrid Linux/Genode (lx_hybrid) binaries can still be started by relabeling the ROM-session route of "ld.lib.so" to the binary name, pretending that the binary is the dynamic linker. This can be achieved via init's label rewriting mechanism: <route> <service name="ROM" unscoped_label="ld.lib.so"> <parent label="test-platform"/> </service> </route> However, as this is quite cryptic and would need to be applied for all lx_hybrid components, the patch adds a shortcut to init's configuration. One can simply add the 'ld="no"' attribute to the <start> node of the corresponding component: <start name="test-platform" ld="no"/> Fixes #2866		2018-08-02 14:36:38 +02:00

README

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.
