Is anyone having any sun4c boxes alive and running Linux?
I have a nice box myself that does not boot - I do not know why.
But we are talking abot slow and old stuff here.
Is it time to drop support for sun4c - or is anyone still
having an interest keeping that platform alive?
Looking into recent history of the kernel only one person
(Mark - copied) seems to have contributed
solely for the purpose of getting a sun4c box working.
Sunstuff has a list of boxes based on sun4c here:
http://sunstuff.org/hardware/systems/sun4/sun4c/
SPARCstation 1, SLC, IPC, 1+, 2, ELC, IPX
SPARCengine 1
To summarize this thread...
There are unsuprisingly some that for sentimental
reasons would like to keep sun4c support in-kernel.
But sun4c is outdated and if anyone want to run something
on a sun4c box the *BSD variants has better performance.
Also considering that sun4c support has been broken for
some time and there is a few changes pending where sun4c
does not make things simpler we will drop sun4c support.
Will Sun4c be dropped for 3.4 or 3.5 ?
(Just so that I can get my hands on a 'last supported' kernel to build
when the network for my remote build host wakes up. :).)
I already took a quick look at it and in the process
I think I uncovered a bug in NMI handling for sun4m
in UP mode. We would call the sun4c nmi trap despite
being a sun4m box - this would not go well.
When I have something tested I will forward my
patches.
