Subject: How to implement kexec on e500 ?
Date: Mon, 29 Jun 2009 21:47:42 +0800 [thread overview]
Message-ID: <e997b7420906290647g7717e55bp210f0f57d8c531c0@mail.gmail.com> (raw)
kernel 2.6.21.7
As we know , kexec stores data for new kernel image , in the form
of a page list.
And kexec uses the physical address of the another page for a
"next-page" pointer.
However, PowerPC e500 does not allow users to turn off the MMU, so we
can not used physical address directly in our code.
Someone suggested that changing relocate_kernel.S to add a TLB 1-to-1
mapping of DRAM .
What does "mapping" mean ?
Any suggestion to implement kexec on e500 ?
Cheers,
wilbur
