Subject: can't print a mmaped region in gdb: Cannot access memory at address ...
Date: Tue, 5 Jul 2005 17:33:11 -0400	[thread overview]
Message-ID: <ecb4efd1050705143364160c24@mail.gmail.com> (raw)

Hi,

I'm trying to debug some code with gdb that mmaps() PCI address space
and mmaps a kernel GFP_DMA buffer. Outside of gdb mmap() interface is
working just fine, but when I try to print the mmaped memory from gdb
I get a 'Cannot access memory at address ...'

Is this a kernel ptrace() issue or a gdb issue? I'm using linux-mips
2.6.11 from 2005.03.18 on an Alchemy Au1550. Google didn't turn up
anything interesting on this subject.

                           Thanks,
                           Clem
