Kernel Version and Flavours

Status:
Master kernels are now at v2.6.37 and remain stable. OMAP3 kernels now switched over to the distro master branch and being used in ARM images. ti-omap4 is a little behind the curve and being investigated.

Old Status:
- Master kernels are now at v2.6.37 and seem pretty stable. OMAP3 kernels now switched over to the distro master branch and being used in ARM images. ti-omap4 is a little behind the curve and being investigated.
- Preliminary uploads of ti-omap4 branches for Natty have now occured, this will form a basis for the natty development. Still waiting on ARM CD image testing. Some investigation of omap3 kernels has commenced.
- Preliminary uploads of ti-omap4 branches for Natty have now occured, this will form a basis for the natty development. Still waiting on ARM CD image testing. A number of minor work items moved out from natty-alpha-1.
- Preliminary testing of the Linaro OMAP3 kernel suggests it does contain the require Ubuntu delta and will boot the Beagle board (our target platform). We are waiting on working ARM CD images to allow substitution of this kernel for further Ubuntu feature testing. As ARM CDs are not expected until the end of the week some of this is likely to miss natty-alpha-1; work items moved out as appropriate.
- Discussions are ongoing as to the kernels to use for omap3, this centres around whether the Linaro kernel is fully featured enough and what levels of support we are able to provide for it. Discussions continue but we are currently waiting on testing of the Linaro kernel against the current userspace. This will not become critical until natty-alpha-2.
- Discussions are ongoing as to the kernels to use for omap3, this centres around whether the Linaro kernel is fully featured enough and what levels of support we are able to provide for it. Currently we are committed only to support for omap4 for ARM.
- Pulled the ports meta-packages into the main master branch to simplify ongoing maintenance.

Work items for natty-alpha-1:
[apw] pull back in ports meta package into our main kernel infrastructure to simplify maintenance:DONE
