5892fba52a Fixed linker scripts on broken crt0.S path 2009-08-29 15:07:12 +03:00
Russel Winder
98ca32779c Make using the task order file work again. 
There are serious problems with the build in that the link order is crucial and should not be.

68f2990885 Return the compilation products from the containers build so they get loaded in. 2009-08-29 08:24:56 +01:00
Russel Winder
5987773f3c First attempt at splitting out the containers build from the SConstruct. 
This creates a runnable final.axf, but the load is not correct and the tests fail to execute.

c311cf72e6 Rearrange the environment construction to support changing toolchain. 2009-08-28 11:49:05 +01:00
Russel Winder
03205855cc Generalize the configuration processing so that the top-level SConstruct only processes the ARCH symbol and prepares the PLATFORM and SUBARCH entries so as to write the config.h. Everything is now entered in the environment so the SConscript files can be responsible fo rthe processing. 2009-08-28 10:39:19 +01:00

a41caeebd2 Created libc under containers/posix which now all tasks use to build. 
There is a problem in the new libc that test0 now misbehaves. Going to be fixed.

117e3482b6 Capabilities for quantitative resources working. 
Status:
- Capability initialization is a bit hacky with dummy current etc.
- All container caps belong to the pager
- Tasks refer to their pager's capabilities for mutex allocation - Hacky.
- Kernel container keeps quantitative caps and memory caps in separate lists - Hacky.

These will all evolve and get fixed.

d3d072e47d Capability accounting for quantitative capabilities - First part done. 
Need to make sure accounting charges correct containers during init.
Therefore kernel resource spending must also be accounted for.

de087eb1f8 Clean up to kernel code, Added `used' field to capabilities 
With the addition of used field, capability structure can be
used for resource accounting over the capability.

9c03d57d63 Carried over pager's virtual address alloc range to its own address space area. 2009-08-19 15:18:10 +03:00
Bahadir Balban
95b7b65c89 Pager virtual address pool bookkeeping added for all pager virtual addresses 
Previously virt_to_phys/phys_to_virt macros were used such that they did a
blind offset translation for creating a pager internal virtual address for
user mappings.

This is now changed such that a properly bookkeeped virtual address pool is
used which will avoid any clashes on the virtual space.
