I realize I may have been a little short in my response about 2.6 and
I apologize. I may have misread what I thought was a cynical and
condescending undertone in earlier posts.
For the record, we dropped pursuing WinCE support at TS so we could
focus more on Linux.
TS will be more willing to invest resources into 2.6 once there is a
clear winner between Cirrus' 2.6 work and the various others working
independently towards 2.6 on the ep93xx processors. Specifically,
once there is general support for this processor in Linus's official
2.6. Its really too risky for us to get involved at this early stage.
We'd really rather invest energy in making Linux more transparent in
customer applications. What we'd like to do is create a more cohesive
environment with better tools (perhaps Eclipse) and to reduce the need
to understand Linux as much as possible for customer applications. It
is been my experience the people with the best product ideas (and the
resources to see them through) are bright individuals yet know nothing
about Linux and aren't keen to learn. Every time I'm on the phone
with one of these companies/individuals I am embarrased when I have to
explain why they have to use "root=/dev/hda1" in one place and
"/dev/ide0/bus0/target0/part1" in another-- they really shouldn't have
to care. This is the kind of stuff that TS will likely invest in if
we have the spare resources. Right now, we're doing all we can to
keep ahead of our custom and new product designs and software
contracting services.
Andy, have you tried using RTAI or Bob Lee's O(1)+low latency 2.4
kernel? What bugs in 2.4 are you running into that aren't in 2.6? It
has been my experience that 2.4 is largely more stable than 2.6 even
on x86 (and there was 2.6 x86 support since 2.6.0). Which drivers
have you had to backport?
