Bahadir Balban 73225a0119 Bootdesc building working 2009-09-30 16:31:34 +03:00
Bahadir Balban 1aa31bc9d5 We have all posix programs getting compiled. 
A lot of hassles on standard c library, mock-up libc, and libposix
headers taken from uClibc clashing has been worked around.

Next:
 - Linker scripts need fixing and adjusting.
 - Bootdesc needs to be generated.
 - Per-container compilation scripts need connecting.

Bahadir Balban 2f2e448667 Removed TEXT_OFFSET parameter from linux configuration 
This parameter does not significantly pose a restriction on configuration.
It can be adjusted depending on phys_offset. Therefore we don't maintain it.

Bahadir Balban fb1de576cb Fixed hexadecimal conversions where output has the most significant bit as 1 
If hex converted had a 1 in the MSB, an L was appended to the number.
The conversion routine removes this.

Bahadir Balban 1c2eaae8b3 Created container.h and added more comprehensive hello world 
Added a per-container container.h that inclues useful definitions.
Hello world now is in a separate file not to modify main too often.
hello world now prints container name and id.

Bahadir Balban bd448babaa Moved scheduler from containers back to being a global. 
It makes more sense to have a scheduler (or runqueue pair) per-cpu
rather than per-container. This provides more flexible global scheduling
policy that is also simpler due to all scheduling details being controlled
from a single point.

Bahadir Balban fa6629800f Coding style changes in kernel startup 2009-09-27 11:47:40 +03:00
Bahadir Balban 6dc68c1776 Force rebuild of bare containers when their linker script changes. 
Small change but useful since linker address configuration changes
should force relinking of container executables.

Bahadir Balban a1fa446ef2 Improved on option parsing help + added it to configure.py as well. 2009-09-26 17:01:44 +03:00
Bahadir Balban 10d2d7269f CML2 rule file is autogenerated from arm.cml and the containers template 
Container rules are too many and repetitive for each container. With this
change, the cml file is autogenerated from a container template cml and
the architecture cml, e.g. arm.cml. -c option determines the number of
containers. See build.py -h for more.
 2009-09-26 16:39:04 +03:00

 2009-09-24 14:12:11 +03:00
Bahadir Balban b91286dcd4 Added a dependency on loader_images_S from final.elf 
This ensures final.elf builds whenever containers.elf file changes.

Bahadir Balban 9bd265c7ec Cannot straightforwardly derive symbols conditionally from multiple sources in CML2 
Ternary expressions on derive statements cause type errors (CML2 Bug?).
	modified:   config/cml/arm.cml
	modified:   scripts/conts/generate_kernel_cinfo.py
 2009-09-23 12:57:43 +03:00
Bahadir Balban 041190b5f2 More fixes to arm.cml, particularly deriving symbols work 
Deriving symbols didn't work because cml2 silently ignored symbols
that were declared previously for derivations. Not pre-declaring derived
symbols have solved the problem.

Bahadir Balban 9bdd951cae Integrated cinfo generation to configure.py 2009-09-22 22:01:25 +03:00

were not sorted properly and consequently an already filled
in container was getting overwritten by the new one.
