This page contains my wishlist / tasks I am working on as well as some random notes.


===== Tasks =====

===== Current status =====

Here is an overview of the current status of the task I am currently working on.

-----

==== IPC Messages ====
  * Some cleanup in the struct messages we are using, especially the ones which are exchanged between userland and the servers. It is done with a few exception which are not userland facing, and the exception of USB-related services.

-----

===== TODO List =====

The following is as much a todo list as random notes.

==== In Progress ====

   * Wiki
      * Document
      * Cross-building & Building
      * NetBooting
      * Using SharedLibs

==== Next up ====

  * Kyua Import does not run on ARM yet. 

  * PKGSRC
    * Currently fails to build
      * icu on clang based builds
      * gdk-pixbuf2
      * gtk2
      * gmp on clang based builds, up to gcc45
      * p5-Module-Build

==== Maybe later? ====


  * Toolchains
    * Check LDFLAGS
    * Check _PROGLDOPTS
    * ARM
      * GOLD patch for ARM?

  * LWIP
    * dhcp
    * bind
    * Remove INET
    * dhclient

  * Build System Upgrade
    * Check Targets  install, sourcesets
    * Target syspkgs does not work
    * Check Target  iso-image-source
    * Check Targets release | iso-image | live-image (HD image) | install-image
    * Create proper sets (base, etc, man, and so on) with packages
    * Generate ISO from build System

  * Dynamic base system?
  * Soft RT?
  * Kernel threads?
  * Efficient SMP?

  * Fix DT_TEXTREL warning

==== I am thinking about ====

  * ARM
    * Console over Framebuffer
    * Hard FP support and ensure:
      * -march=armv7-a
      * -mfloat=hard
      * -mfpu=vfpv3-d16
    * Domain IDs for main servers + Mappings in User processes
    * ASID tagging (Beng's patch may be ok now?)

  * INTEL/x86_32
    * VGA/VESA Framebuffer (Higher text resolutions)
    * Console over Framebuffer

===== Towards an optional POSIX layer for MINIX? =====

In some embedded scenario, there is no need for all the POSIX APIs. I think that given MINIX structure, it should be possible to have a system without even filesystem support for example. In such systems all the functionnality required is simply implemented through a set of specific (and adhoc) services.

Because of interdependencies in our current services (VM, VFS, PM, RS) it is not possible at the moment to reduced the system to a bare minimum of just the microkernel, a few drivers, VM, and RS.

<code>
# Server re-organisation, if we aim one day to have a smaller subset without 
# posix support.
# Not possible without right now, the servers have some inter-dependencies.
