Subject: [PATCH 067/120] MIPS: PS2: IOP: Module linking support
Date: Sun, 1 Sep 2019 18:10:53 +0200
Message-ID: <d9400024551bfad4e8bbe1ebb4dc3d521da28045.1567326213.git.noring@nocrew.org> (raw)
In-Reply-To: <cover.1567326213.git.noring@nocrew.org>

IOP modules are IRX objects based on the executable and linkable format
(ELF). All valid IOP modules have a special .iopmod section containing
the module name, version, etc.

When the IOP is reset, a set of modules are automatically linked from
read-only memory (ROM). Non-ROM modules are handled as firmware by the
IOP module linker.

IOP modules may import and export any number of library functions,
including non at all. Imported libraries must be resolved and prelinked
before the given module is allowed to link itself. Other modules can
link with its exported libraries.

IOP modules begin to execute their entry function immediately after
linking. The modules can either stay resident in the IOP, and provide
services, or unlink themselves when exiting the entry function. Many
modules provide remote procedure call (RPC) services via the sub-system
interface (SIF).
