Bahadir Balban ef238485c2 Merge branch 'containersBuildDevel' of http://www.russel.org.uk/Git/Codezero into russel-incoming 2009-08-29 17:11:52 +03:00
Bahadir Balban 7b5a3c2845 Moved userspace libc to posix container directory. 
Issues:
- MM0 needs separate subset of libc and not link with libposix
- FS0 needs separate subset of libc and not link with libposix
- libposix need transforming into a full-blown uclibc for test0
- libc really is a pseudo-libc that needs to be replaced as above.
- Done some hacking to avoid conflicts between pseudo-libc and libposix headers.

Now system working as original, (e.g. execve etc. working)

Bahadir Balban 2bbb963848 Added untracked crt0.S 2009-08-29 15:09:48 +03:00
Bahadir Balban 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.

Bahadir Balban 763d4c7012 Removed accidentally added config file. 2009-08-29 14:31:03 +03:00
Bahadir Balban 779429d289 Intermediate stage in reincorporating old libc into userspace tasks. 2009-08-29 14:29:57 +03:00
Russel Winder 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.
 2009-08-29 08:07:50 +01:00
Russel Winder 9e894274a3 Refactor the build to try and get as much material as possible out of SConstruct. 2009-08-28 14:10:24 +01:00
Russel Winder 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
Russel Winder f6707e3ca7 Simplify the configuration file parsing so as to prepare for more generality. 2009-08-28 10:19:45 +01:00
Russel Winder 079b031616 Add check to ensure the source for the required device driver is actually present. 2009-08-28 09:55:55 +01:00
Russel Winder 591cac56cf Change the name of the IRQ symbol in the CML2 configuration so that the DRIVER_... symbol name structure matches the name structure of the kernel source hierarchy. 2009-08-28 09:55:20 +01:00
Russel Winder 34a804eb4d Trivial changes to sync up. 2009-08-28 09:28:24 +01:00
Russel Winder 187b70a829 Remove redundant comments. 2009-08-28 09:23:56 +01:00
Russel Winder 9033503283 Merge branch 'containers' into containersBuildDevel 2009-08-27 17:01:29 +01:00
Russel Winder 673b41c3a6 Simplify the top-level SConstruct a bit by transfering responsibility for ensuring the dependency on the configuration files to the SConscript files. 2009-08-27 16:59:52 +01:00
Russel Winder 6ca0f2607a Switch to using a different strategy for building the kernel. 2009-08-27 16:43:47 +01:00
Bahadir Balban 7b27d7f996 Turned off verbose test printout 2009-08-27 17:37:51 +03:00
Russel Winder 34c2156bc4 Remove redundant file. 2009-08-27 15:35:52 +01:00
Bahadir Balban 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.
 2009-08-27 12:00:04 +03:00
Bahadir Balban 87e2aeaf58 Moved tasks/* into containers/posix 2009-08-25 14:34:21 +03:00
Bahadir Balban 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.
 2009-08-22 23:41:53 +03:00
Bahadir Balban 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.
 2009-08-22 12:09:51 +03:00
Bahadir Balban 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.
 2009-08-21 12:10:34 +03:00
Bahadir Balban d14f91c668 Cleaned up pager initialization code. 2009-08-19 17:07:08 +03:00
Bahadir Balban dabc448c4e Added freeing of pager init memory, but this memory is currently not utilized. 2009-08-19 16:26:44 +03:00
Bahadir Balban 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.

Bahadir Balban c64c1a4515 MM0 do_close() without IO was segfaulting. now fixed. 
This was triggered by incorrect test0 build that omits to embed
the test executable.
