Subject: mapping 36 bit physical addresses into 32 bit virtual
Date: Tue, 15 Oct 2002 09:59:47 -0700 (PDT)	[thread overview]
Message-ID: <20021015165947.50642.qmail@web13801.mail.yahoo.com> (raw)

Hi,

I'm developing some drivers for the AU1000 under
Mountain Vista's 2.4.17 sherman release. The AU1000 is
a MIPS based SOC with a 36 bit internal address bus
and a 32 bit MIPS cpu.  According to the documentation
the MIPS' TLB is able to map 32 bit virtual addresses
to 36 bit physical addresses, however I cannot figure
out how to get Linux to set this up.  I've looked at
ioremap which only takes unsigned long (32bits) as an
argument to assign a virtual address.  Is there
another way?

thanks

Padraig
