Subject: Various DIMM-s problem on 860
Date: Thu, 25 Apr 2002 11:23:56 +0200 [thread overview]
Message-ID: <3CC7CB2C.1010106@dgt-lab.com.pl> (raw)
I have questin on using DIMM with 860
There are no probelems with DIMM-s on 8260, but on 860 there are no
specialized BankSelect lines.
But there are plenty of DIMM types
On 860 there are some choises:
-there are a lot of jumpers (or 0-ohm reistors)
-use only one type of DIMM(which is not acceptable)
-use somechip selects,and there are MEMORY HOLES in them
Q: Is there any simpleway to use non-linear addresedmemory in linux? If
so, how to enable this in kernel?
for example there is:
0x0000_0000 .. 0x001f.ffff memory
0x0010_0000 .. 0x002f.ffff NOTHING!!!
0x0020_0000 .. 0x003f.ffff memory
