Subject: Problem using more than 2 GB with my driver
Date: Tue, 30 Sep 2003 14:13:30 +0000 [thread overview]
Message-ID: <marc-linux-ia64-106494885715850@msgid-missing> (raw)
Hello,
I've got a little problem:
I wrote a driver using the physical addresses of a buffer computed by
the "ia64_tpa" function (but no using DMA) that works only on machines
with 2Gb of RAM at most. With more RAM, the machine crashes very badly
after a while, and even KDB is not usable...
If anybody has an a idea ;-)
Patrice
