# TODO as of November, 2012
|
|
|
|
* force a build run
|
|
|
|
* Integrate Cairo into build toolchain
|
|
* autogen means extra effort needed
|
|
* required to ship with new compositor
|
|
* Fix static initializers in C++
|
|
* The best method for this is probably going to be writing a dynamic loader, so...
|
|
* Write a dynamic loader
|
|
* Pretty much everything below
|
|
|
|
# TODO for 0.4.0 Distribution Release
|
|
|
|
* User Interface
|
|
* ~~Graphical Login~~
|
|
* More applications
|
|
* Working boot on real hardware
|
|
|
|
# TODO for 0.4.5
|
|
|
|
* CD support
|
|
* Boot from "CD"
|
|
* Distribute with Grub
|
|
* CD image generator in-repo
|
|
* Stable Harddisk writes
|
|
* Screenshot functionality
|
|
* Attempt an installer?
|
|
|
|
# Doc Revamp
|
|
|
|
* Get rid of old, outdated TeX/PDF manual
|
|
* Build a modern doxygen-powered documentation system for
|
|
kernel functions for use by kernel developers.
|
|
* Also include doxygen documentation for included libraries
|
|
(lib/graphics, etc.)
|
|
|
|
# TODO for Microkernel Launch (0.5.0?)
|
|
|
|
* Replace ramdisks with ELF service executables
|
|
* Boot with multiple modules = boot with multiple services.
|
|
* vfs.srv, for example
|
|
* VFS as a service.
|
|
* It would be super awesome to write this in a language that is more flexible.
|
|
* Actual file system drivers as separate modules, or what?
|
|
* Service bindings
|
|
* Essentially, a system call interface to discovering available services.
|
|
* `require_service(...)` system call for usable errors when a service is missing?
|
|
* Deprecate old graphics applications
|
|
* And rename the windowed versions.
|
|
* Environment variables
|
|
* Support them in general
|
|
* Push things like graphics parameters to environment variables
|
|
* Integrate service-based VFS into C library
|
|
* Which probably means integrating shmem services into the C library
|
|
* Services in a separate ring
|
|
* Compositor as a service
|
|
* Compositor shmem names integrated with service discovery
|
|
* For VFS, need better IPC for cross-process read/write/info/readdir/etc. calls
|
|
|
|
## Service Modules (aka "Services")
|
|
|
|
* `vfs.srv` The virtual file system server. (required to provide file system endpoints)
|
|
* `ext2.srv` Ext2 file system server. (provides `/`)
|
|
* `ata.srv` ATA disk access server. (provides `/dev/hd*`)
|
|
* `compositor.srv` The window compositing server. (provides shmem regions)
|
|
* `ps2_hid.srv` The keyboard/mouse server. (provides `/dev/input/ps2/*`)
|
|
* `serial.srv` UART serial communication server (provides `/dev/ttyS*`)
|
|
|
|
### Future Servers
|
|
|
|
* `usb.srv` Generic USB device server (provides `/dev/input/usb/*`)
|
|
* `proc.srv` Process information server (provides `/dev/proc`; uses lots of kernel bindings)
|
|
* `net.srv` Networking server (provides `/dev/net`)
|
|
* `gfx.srv` Block-access graphics server (provides `/dev/fb*`)
|
|
|
|
## Things that are not services
|
|
|
|
* ELF support is not a service
|
|
|
|
# TODO as of Septemember 2012
|
|
|
|
## C++
|
|
* ~~Build with C++ support~~
|
|
|
|
## Terminal Fixes ##
|
|
* Mouse features; mouse support in windowed mode
|
|
* ~~Tab completion in shell (this is mostly a shell-specific thing)~~
|
|
|
|
## Windowing System ##
|
|
* ~~Graphical Login Manager~~
|
|
* Finish GUI toolkit
|
|
* File manager app
|
|
|
|
## Harddisk Drive Extras
|
|
* VFS support is still almost entirely non-existent
|
|
* Write support for EXT2 is still sketchy
|
|
* Still lacking fast read/write for IDE - needs more DMA!
|
|
|
|
## Toolchain
|
|
* Finish GCC port
|
|
* Still missing a few things in the underlying C library
|
|
* Ideally, also want to be able to build natively, so need scripting, build utils, etc.
|
|
* Port ncurses/vim/etc.
|
|
* Native development requires good tools.
|
|
* Also port genext2fs.
|
|
* Directory support needs to be better integrated into the C library still
|
|
|
|
## Microkernal Readiness
|
|
|
|
* ~~Deprecate ramdisks~~ **replaced with new ramdisk module, works better**
|
|
* Haven't used them in development in over a year
|
|
* Not useful anywhere else due to their limiting sizes
|
|
* Implement module execution
|
|
* Instead of loading a ramdisk, modules should be standard binaries
|
|
* The binaries will be executed in a new "service mode"
|
|
* Implement "servicespace"
|
|
* Userspace, but at a different ring
|
|
* Special access features, like extended port access
|
|
* Higher priority scheduling
|
|
|
|
### Services to Implement
|
|
|
|
* PCI Service
|
|
* Graphics Management Service
|
|
* Compositor as a service?
|
|
* Virtual File System Service
|
|
|
|
## Old I/O goals
|
|
|
|
### I/O
|
|
* `/dev` file system
|
|
* `/dev/fbN` and `/dev/ttyN` for virtual framebuffer terminals and graphics
|
|
* `/dev/ttyS0` for serial I/O
|
|
* SATA read/write drivers (`/dev/sdaN`)
|
|
* `/dev/ramdisk` (read-only)
|
|
* EXT2 drivers should operate on a `/dev/*` file
|
|
* Mounting of `/dev/*` files using a filesystem handler
|
|
* VFS tree
|
