This patch replaces exceptions of the PD session RPC interface with result types. The change of the quota-transfer RPC functions required the adaptation of base/quota_transfer.h and base/child.h. The 'alloc_signal_source' method has been renamed to 'signal_source' to avoid an exceedingly long name of the corresponding result type. The Pd_session::map function takes a 'Virt_range' instead of basic-type arguments. The 'Signal_source_capability' alias for 'Capability<Signal_source>' has been removed. Issue #5245
This is the generic Genode base system, which consists of two parts: :_Core_: is the root of the Genode component tree. It provides abstractions for the lowest-level hardware resources such as RAM, ROM, CPU, and device access. All generic parts of core can be found here. For kernel-specific parts, refer to the appropriate 'base-<kernel>' directory. :_Base libraries and interfaces: that are used by each Genode component to interact with other components. This is the glue that holds everything together. Depending on the used kernel, core may export information about the hardware platform as a ROM called 'platform_info'. For example, if the ACPI RSDT and XSDT physical pointer are reported by the used kernel and/or bootloader, core provides this information in the ROM as follows. !<platform_info> ! <acpi revision="2" rsdt="0x1fe93074" xsdt="0x1fe930e8"/> ! <boot> ! <framebuffer phys="0x7300000" width="1024" height="768" bpp="32"/> ! </boot> !</platform_info> If the graphics device is initialised and can be directly used by a framebuffer driver, core provides the physical pointer to the framebuffer, the resolution, and color depth in bits.
