Stable version and repository loc

Stable version and repository loc

[alan]

Hola,



What is the latest version of the Linux kernel OMAP tree that is considered
stable?  I'm in the middle of bringing up a bare-metal roll of Linux on a
derivative of the AM3517 family (Jacinto 3) on a commercial automotive radio.
 I'm new to Linux on OMAP but old to Linux kernel development itself (since
pre-1.0).  It appears the latest PSP from TI contains a version of 2.6.37 but
it's main line cousin is more than a year old now.  And from lurking here on the
very active Linux OMAP list, that's likely a enormous number of changes.  I'm
just looking for the most current stable starting point and working up from
there as technical problems dictate.



I'm also looking for the git tree.  There are many broken links in the Getting
Started section of:



http://omappedia.org/wiki/Linux_OMAP_Kernel_Project
<http://omappedia.org/wiki/Linux_OMAP_Kernel_Project>



And the ones that work near the end don't appear to line up with my recent
memory of list traffic.



Any help/pointers would be greatly appreciated.

The stable version is most recent mainline Linux kernel tree, that is
v3.3 currently. All the other branches are development branches for the
upcoming merge window, or some legacy patches that we still carry around
that are not ready to be merged yet.

Tony

Alan, you should be aware that there are some issues with am35x support.
They are being worked on but aren't there yet.  To get by for now, make
sure you add 'nohlt' to your kernel cmdline and do not enable
CONFIG_CPU_IDLE.  If you want to suspend/resume (i.e., suspend-to-RAM),
you will have more issues so avoid doing that if you can.
