Hi, If I enable SMP then I can build a 2.6.28 kernel with gcc 4.3.5 that WILL boot on the PowerMac8600 (single 750GX). The previously mentioned G4 that runs is a dual cpu beast and thus also runs SMP.
I at least know this (ok, I THINK I know): For non-SMP: The spinlock 'acct_lock' in kernel/acct.c that IS present in 3.4.6 (i.e. kernel 2.6.28 compiled with gcc 3.4.6). Not so much for 4.3.5. I have not yet done a general 4.3.5 compiled 2.6.28 spinlock safari. Don't some funky, optimizery things happen to spinlocks for the NON-smp case? I'll see what the 4.2.x gcc does. Thanks! kevin P.S.: There is one other difference for the SMP 4.3.5 compiled 2.6.28: my 750gx cpufreq driver gets disabled. It is fairly isolated code though. Should not be able to nuke the spinlock in kernel/acct.c On Fri, Jan 21, 2011 at 1:26 PM, kevin diggs <diggskevi...@gmail.com> wrote: > Hi, > > Anyone familiar with BootX?
