Sure, sorry to be vague on the platform detail. I actually tried on two Malta configurations, CoreFPGA6 interAptiv 2MPF = (2 cores, 2 VPE, 4TC), and CoreFPGA3 34Kc MT (2VPE 9TC). > >> I don't really know broadcom platforms and SGI platforms well so >> changes to those platforms are kept minimal (no functional change). > > Technically I could run it on my SB1250, but I'm too overloaded now t= o=20 > commit to any timescale. Sorry. No worries, I'll try to fetch a BMIPS3000 SMP router to get Broadcom pla= tform undercover. Thanks > > Maciej --=20 - Jiaxun
