Subject: [PATCH 00/10] Enhance /dev/mem to allow read/write of arbitrary physical addresses
Date: Fri, 17 Jun 2011 08:38:25 +0000 [thread overview]
Message-ID: <201106171038.25988.ptesarik@suse.cz> (raw)
This patch series enhances /dev/mem, so that read and write is possible
at any address. The patchset includes actual implementation for x86.
Petr Tesarik (10):
Return EOF on out-of-bounds read from /dev/mem
(un)xlate_dev_mem_ptr: use phys_addr_t for the @phys parameter
x86: translate highmem /dev/mem pointers
ia64: change xlate_dev_mem_ptr's argument to phys_addr_t
valid_phys_addr_range: use phys_addr_t for the @addr parameter
sh: change valid_phys_addr_range's @addr param to phys_addr_t
arm: change valid_phys_addr_range's @addr param to phys_addr_t
ia64: change valid_phys_addr_range's @addr param to phys_addr_t
x86: provide arch-specific valid_phys_addr_range()
Allow reading/writing all memory through /dev/mem
