loader
|
adapting the pmode tutorial of TRAN to a small os, featuring VM86
for mouse control, exception handling through a text debug pannel
assembly implementation of LOSTZONE, BLOCMAN and PAGER1 as S-DLODS.
looks more like a dos extender than a real kernel, so far.

| 0.3.x |
Kernel Dynamix System
|
This version see the rise of KDS: naming, services ...
Though KDS is restricted to single address space and functions
callbacks.
| 0.3.1 |
Adding BTree support, basic kds naming schemes, Virtual Sets Extensions design, cursors for BTrees
| | 0.3.2 |
Ensuring a "true" 64K limit to kernel file (rather than a 64K virtual image including uninitialised datas :)

Kds Naming System available, working on services (tests under Linux system faking a Clicker).
| | 0.3.6 |
Adding a KDS info shower, fighting with the 64K barrier
| | 0.3.8 |

|
|
| 0.4.x |
Slang support and modules management. Some debugs in memory management.
|
| 0.4.1 |
working on Slang compiler, added services exports for the Kernel,
adding the Interner in KDS, kernel adds its internal symbols
(from Slang analysis) at startup
| | 0.4.2 |

a client of the memmap service.
| | 0.4.3 |

| | 0.4.5 |
Hello from Clicker 0.4.5 module added. Paging activation,
debugging aligned allocation. Paging-aware SOS.

module directory framework, modloadall, page fault handlers.
| | 0.4.9 |
Paging debug pannel, modmaker detects unresolved symbols.
|
|
| 0.5.x |
Initiating Multitasking system
|
This evolution adds extended memory management that is needed to
achieve multitasking like segmentation control, stacks management, etc.
| 0.5.2 |
debugging SOS for IBM ThinkPad compatibility, correction of module maker, introducing segmentation management, adding the LOG system and converting some SIGNs into LOGs
| | 0.5.4 |
Descriptortables support written and tested.
| | 0.5.6 |
Allocation/Dellocation of zones without causing page faults
| | 0.5.8 |
Automatically-zeroed page now work. pager system should now be stable
| | 0.5.10 |
clock service, pages cluster introduced, stack memory objects written, Debug now support fast forward and break.
|
|
| 0.6.x |
Multitasking system
|
This evolution adds the support of multithreading in the microkernel. At a final point, we should be able to define asynchronous servers that run in a separate thread and receive their request from a message queue.
| 0.6.0 |
First thread creation, thread switching is done manually by calling/jumping to a tss. Also introduce a task debug pannel
| | 0.6.2 |
introducing the dispatcher, the halt task, making print buffer glocal and multithread-compliant.
| | 0.6.4 |
catching stack overflow through stack faults rather than page faults, introducing the crashTask for intercepting very auwful panics (that would have made the CPU reboot otherwise).
| | 0.6.6 |
some patches in module loader, upgrading clock to 1KHz, deferring task switches when handling an interrupt.
| | 0.6.8 |
module format version 1.2 (no more bss/init overlayering), creating PAGER-II module, introducing a user heap (that will later turn into private heap).
| | 0.6.10 |
readers/writers sharing, process manager (for truly killing threads)
| | 0.6.12 |
remote-kill and deferred-kill, module manager, thread shielding
| | 0.6.14 |
modules for semaphores, reader, writers, scheduler hot-swapping
| | 0.6.16 |
cleaning up, module format 1.3, slang update _thread_ and _queue_, asynchronous servers support
|
|
| 0.7.x |
user level & multiprocess
|
| Main target of version 0.7.x is to add user-level
and multiprocess support. At version 0.8.0, it should be possible to
open a user program by giving a file name to a "exec" system call from
another user-program, and to simply define new resource classes (like
a message printer, for instance).
Evolution 7 is also the time to make a LOT of clean up within the
source code. The version 0.8.0 of Clicker microkernel should be
AS CLEAN AS POSSIBLE, using no hacks, being fully-documented and
should be distributed as a .tar.gz (rather than legacy .zip)
separately from the extensions modules (for debug, demos, etc.)
Therefore - and because i'm no more a student - Evolution 7 is
one of the longest in Clicker's history.
