Subject: which driver for mmap-able battery-backed SRAM ?
Date: Tue, 11 Feb 2014 20:29:10 +0100 [thread overview]
Message-ID: <20140211192910.GA23223@frolo.macqel> (raw)
Hi mtd experts,
I try to find the right driver for a memory-mapped battery-backed SRAM chip.
I have tried two drivers :
"mmio-sram" drivers/misc/sram.c
and
"mtd-ram" drivers/mtd/chips/map_ram.c
but none of them provides me the expected interface : being able to mmap
it in a user program, and ensure that every write access to it happens
at the moment it is executed in the user program.
Is there already a driver that has those functionalities, or which one should
I enhance ?
TIA
