Implement support for the non-pmem exclusive secure erase, per CXL specs. Create a write-only 'security/erase' sysfs file to perform the requested operation. As with the sanitation this requires the device being offline and thus no active HPA-DPA decoding. The expectation is that userspace can use it such as: cxl disable-memdev memX echo 1 > /sys/bus/cxl/devices/memX/security/erase cxl enable-memdev memX Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Dave Jiang <dave.jiang@intel.com> Reviewed-by: Fan Ni <fan.ni@samsung.com> Signed-off-by: Davidlohr Bueso <dave@stgolabs.net> Link: https://lore.kernel.org/r/20230612181038.14421-7-dave@stgolabs.net Signed-off-by: Dan Williams <dan.j.williams@intel.com> |
