Subject: Allocating a page of memory with a given physical address
Date: Thu, 08 Jun 2000 16:44:21 -0500 [thread overview]
Message-ID: <20000608220756Z131165-245+106@kanga.kvack.org> (raw)
I have an application that needs to allocate a page of RAM on a given physical
address. IOW, say I have a physical address (e.g. 0x0CDB5000 on a 256MB
machine), and I know (via the mem_map array) that it's not being used by
anything. What I need to do know is allocate that page of memory so that no one
else can allocate it (via a memory allocation function like get_free_page or
malloc).
Is this currently possible? If not, is anyone working on adding it to a future
kernel? And if not, is anyone willing to help me implement it or at least tell
me how I should proceed?
