I can't comment on your tweak to 2.6.24.7 without seeing it as a patch diff. I am no longer associated with MIPS Technologies and no longer have access to my email archives from that period. If I did, I could tell you which LMO kernel version(s) had SMTC working "out of the box". There definitely was at least one, and I commented on it in an email. You might be able to find it in the LMO email archives, but it's possible that I only sent it to a MIPS internal mailing list. There was also a message I wrote that I had *thought* had gone to the LMO mailing list, but may have only been sent to a group of internal MIPS and customer engineers, in which I described the recommended procedure for debugging exactly this canonical problem with porting SMTC. The recommended procedure was, and remains, to isolate clock propagation problems by using command line options "maxtcs=" and "maxvpes=". First, boot your SMTC kernel with maxtcs=1 and maxvpes=1, a virtual uniprocessor. If that doesn't run, you've got some fundamental problem with support for your platform, or someone has really fundamentally broken the SMTC build somewhere. Next, try booting with maxtcs=2 and maxvpes=1, then with no constraint on maxtcs and maxvpes=1. If those fail, your problem is probably in the interrupt mask management algorithms I described. On the other hand, if you boot with maxtcs=2 and maxvpes=2, there will be only one TC per VPE and far less vulnerability to interrupt mask lockup, but you need to have cross-VPE IPI interrupts working. The preferred method of doing cross-VPE IPIs would be to use a physical interrupt input that's instantiated per-VPE and manipulable by software. Malta didn't have one, so there's the historical hack of using MIPS MT instructions to freeze the other VPE and set up a software interrupt using MTTR to the remote Cause register. The PMC-Sierra platforms did, if I recall correctly, have some kind of register that one could write to cause a real cross-VPE hardware interrupt, but I don't recall whether it got used in the SMTC port. Your dump below looks as if it comes from 2 TCs running on 2 VPEs, and that the interrupt mask issues I alluded to earlier are neither relevant nor manifest. It looks instead as if the initialization of "CPU 1" (VPE1/TC1) may not have been done properly. Under normal operation, it would be pretty rare to catch TC 1 in the exception vector dispatch code, so the first hypothesis that comes to mind is that something isn't right in the vector/handler setup, and TC 1 is stuck in an infinite exception loop, unable to handshake with TC 0 and thus locking up the system. But that's just my best guess based on limited data. Regards, Kevin K.
