Hello,

So, I applied the patches to NetBSD 6 source, and compiled up my specific kernel for the Sun Fire v240 and a GENERIC.UP for the Sun Netra T1 model 200, and booted them. Both work, and the good timekeeping continues for the v240.

Nice :)

One thing I noticed that differs on the Netra between patch one and two: when booting the first set of patches (which crashed late in the process - probably at/near where timecounter selection is reported) is that during CPU probe (near the top), the first set of patches caused the kernel to emit this:

cpu0: system tick frequency 11 MHz

So there's ... something there that they found.

The UltraSPARC-IIe has the 2nd timer, but it's implemented differently than on UltraSPARC-III ( see Takeshi Nakayama's mail ). My patch only supports it on UltraSPARC-III for now ( I don't have any IIe-style hardware so someone else will have to do that )

have fun
Michael
