The former 'Genode::Timed_semaphore' mechanism is moved to the private part of the two remaining users, namely dde_rump and the libc. Note there are now two private copies of 'timed_semaphore.h'. This should be regarded as an interim step until the use of this mechanism is removed from both users. This patch also cleans up the mechanism from legacy Genode API calls and global side effects (alarm-thread singleton). The test/timed_semaphore is now located at the libports repository as it now tests a mechanism of the libc. The former timed_semaphore library is no more. Fixes #3121
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.
