Hi all,
The issue of a 2.6 kernel for the TS7200 has once again been raised. In
my opinion, the path to a useful 2.6 kernel is dependent upon a
well-understood kernel patch chain to generate the existing 2.4 TS7250
kernel.
TS documentation indicates that the TS kernel is patched against a
Cirrus EP93xx kernel, which is in turn patched against kernel.org
sources.
The production TS7250 kernel, labeled 2.4.26-vrs1-cirrus-1-2-1-ts8, is
claimed to derive from a Cirrus 2.4.26 kernel. However, I have not
found a 2.4.26 kernel from Cirrus, and when I ask Cirrus about a 2.4.26
kernel they are puzzled. (Cirrus does publish 2.4.18, 2.4.19, and
2.4.21 kernels for the EP93xx.) Thus, I have been unable to reconstruct
the first link in the patch chain - the patch from kernel.org 2.4.26
source to a Cirrus EP93xx 2.4.26 kernel. Furthermore, when I requested
TS patch sources to the Cirrus kernel, TS suggested that I generate the
patches from a diff of the TS published source against the (nonexistent)
Cirrus EP93xx 2.4.26 kernel. In other words, I'm stuck here.
If we (with TS assistance - Jesse?) can obtain the TS-specific patches
used for the 2.4 kernel, it should be fairly easy to get to a working
2.6 TS kernel. There is already a good 2.6.12 patch set for EP93xx
(http://members.inode.at/m.burian/ep93xx/), which I have tested on my
Cirrus EDB9301 eval board. With this patch set, and some mods to the TS
patches, a TS 2.6.12 kernel should be reasonably straightforward.
So - TS folks - is there any way to isolate and publish the TS7200 /
TS7250 specific patches against the Cirrus 2.4 kernel, so we can analyze
the problem and get started?
Thanks
Scott
