Thank you for all of your hard work over the years; I've appreciated it
and I suspect many others have as well.

Cheers,

Reducing involvement with sparc port

2009-06-25 Thread Jurij Smakov
Hi,

After giving it some thought, I've decided to significantly reduce my
involvement with the sparc port, mainly due to lack of motivation and
other responsibilities I'm in the process of assuming. Last two Debian
kernels (2.6.29 and 2.6.30) do not even boot on my sparc box, and I have
no interest whatsoever in tracking the reason for that down. If someone
out there is still interested in actively keeping sparc port afloat, I
would suggest to try and sort these kernel issues out first. Another
couple of problems I've made pretty much no progress on are disabling
CONFIG_PROM_CONSOLE (bug 525958) and adding support for loading VIO
devices to udev (bug 526621). The former should improve the performance
on Niagara quite a bit, the latter should make the LDOMs usable on sparc
without manual tweaking.

Good luck.

 +1. dropping hppa as a release architecture was not communicated by the 
 release
 team at all.  I did spend some time to get gcj / default-jdk working on 
 hppa,
 and some money (buying a new disk for a hppa machine) to help this port.  
 The
 time and the money could have spent better, if d-r would have better
 communicated about their intent.

which of the previous statements did you check? E.g. speed comparing the current
32bit v8 with 64bit ultrasparc code?

and even then I wouldn't care that much if it becomes maintainable.
