Here is another version of the same trivial pmem driver, because two obviously aren't enough. The first patch is the same pmem driver that Ross posted a short time ago, just modified to use platform_devices to find the persistant memory region instead of hardconding it in the Kconfig. This allows to keep pmem.c separate from any discovery mechanism, but still allow auto-discovery. The other two patches are a heavily rewritten version of the code that Intel gave to various storage vendors to discover the type 12 (and earlier type 6) nvdimms, which I massaged into a form that is hopefully suitable for mainline. Note that pmem.c really is the minimal version as I think we need something included ASAP. We'll eventually need to be able to do other I/O from and to it, and as most people know everyone has their own preferre method to do it, which I'd like to discuss once we have the basic driver in. This has been tested both with a real NVDIMM on a system with a type 12 capable bios, as well as with "fake persistent" memory using the memmap= option. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
