slackware/14.0/patches/packages/linux-3.2.45/BROKEN.TXT


Pat,

You asked for comments about supporting the non smp version of the kernel.

I have a PI and a PII machine. I have Slackware 14.0 installed on both. I don't use them often, part of me screams to retire the machines, but I still tinker with them occasionally. I do not use the smp kernel with those machines.

I don't remember whether I ever tried using the smp kernel. I'll try to find time to tinker with the smp kernel on those machines. My primary concern is the PI system. I know from experience that many Live CDs no longer function on that machine because most are now built with kernels that only support i686+.

On the other hand, I could build my own kernels. I did that for many years. The past couple of years I stopped doing that, choosing instead to just use the generic kernel and an initrd.

Followup: The smp kernel doesn't work on the PI system, resulting in the infamous failure message "This kernel requires the following features not present on the CPU: pae cmov." The smp kernel works on the PII machine.

Note: Pat, if you decide to stop supporting the non smp kernel, that would seem to modify the basic Slackware requirements from i486 to i686 because the smp kernal no longer will run with anything less than i686.

If you drop the non-SMP kernel there is no way to install Slackware on machines without PAE, like the Pentium M CPUs with 400MHz FSB, Geode LX or VIA C3.

While I tend to use the SMP kernel on systems that'll run it, I'd also agree with keeping a non-SMP available as an option, namely because Slackware is my main general use Linux, and I like retaining the option to use it on some older hardware + certain relatively modern systems that don't have PAE, as TobiSGD points out.

Before this evolves into another long thread, that BROKEN.TXT file is old (note the timestamp), and isn't in -current any longer. The only reason it's in the patches directory is because it got copied out of what shipped with 14.0. As noted, since the SMP kernel started to use PAE we need the other kernel as a fallback for systems that don't support that (which will always be single core anyway). The uniprocessor kernel won't be going anywhere.
