Hi, I plan to port linux-mips to a a 32bit 4KEc based (little endian) hardware design. I have three questions: Q1- The nice book `see mips run' states that it's better that the physical address map fits entirely in kseg1 (in 0x0-0x2000_0000). I would not be the first to plan for a lot of RAM and I understand HIGHMEM patch is ok if an extra RAM area is out of reach of kseg1. But what if my PCI devices I/O do not lie in kseg1? I may program the TLB to see them thru kseg2 (but kseg2 seems to be the place where page tables are stored...) Q2- Most hardware platforms have their SDRAM chips mapped at physical address 0x0. Mine does not. Am I going ahead of problems? It seems to be assumed at a lot of places (I have already ported YAMON). Q3- I'd rather stick to a 2.4.x linux port. But... should I use: a- the latest official 2.4.x kernel b- the latest 2.4.x-preY kernel c- the latest linux-mips.org 2.4.x kernel d- cvs -z3 -d :pserver:cvs@xxxxxxxxxxxxxxxxxx:/home/cvs co -r linux_2_4 ? Thanks for any useful advise. Sincerely yours, -- E.M. key A1A84D4C
