This change adds a new interface DSL for specifying objects (with
methods) and interfaces (that expose objects, and optionally have their
own methods).
Significant changes:
- Add the new scripts/definitions Python module to parse the DSL
- Add the new definitions directory containing DSL definition files
- Use cog to generate syscall-related code in kernel and libj6
- Unify ordering of pointer + length pairs in interfaces
I'm a tabs guy. I like tabs, it's an elegant way to represent
indentation instead of brute-forcing it. But I have to admit that the
world seems to be going towards spaces, and tooling tends not to play
nice with tabs. So here we go, changing the whole repo to spaces since
I'm getting tired of all the inconsistent formatting.
Create a new usermode program, srv.init, and have it read the initial
module_page args sent to it by the bootloader. Doesn't yet do anything
useful but sets up the way for loading the rest of the programs from
srv.init.
Other (mostly) related changes:
- bootloader: The allocator now has a function for allocating init
modules out of a modules_page slab. Also changed how the allocator is
initialized and passes the allocation register and modules_page list
to efi_main().
- bootloader: Expose the simple wstrlen() to the rest of the program
- bootloader: Move check_cpu_supported() to hardware.cpp
- bootloader: Moved program_desc to loader.h and made the loader
functions take it as an argument instead of paths.
- kernel: Rename the system_map_mmio syscall to system_map_phys, and
stop having it default those VMAs to having the vm_flags::mmio flag.
Added a new flag mask, vm_flags::driver_mask, so that drivers can be
allowed to ask for the MMIO flag.
- kernel: Rename load_simple_process() to load_init_server() and got rid
of all the stack setup routines in memory_bootstrap.cpp and task.s
- Fixed formatting in config/debug.toml, undefined __linux and other
linux-specific defines, and got rid of _LIBCPP_HAS_THREAD_API_EXTERNAL
because that's just not true.
A long overdue cleanup of the src/ tree.
- Moved src/drivers to src/user because it contains more than drivers
- Removed src/drivers/ahci because it's unused - will restore it when I
make a real AHCI driver
- Removed unused src/tools
- Moved kernel.ld (the only used file under src/arch) to src/kernel for
now, if/when there's a multi-platform effort that should be figured
out as part of it
- Removed the rest of the unused src/arch
- Renamed 'fb' to 'drv.uefi_fb' and 'nulldrv' to 'testapp'
