From d7f96f97c4031fa4ffdb7801f9aae23e96170a6f Mon Sep 17 00:00:00 2001 From: Ivan Khoronzhuk Date: Thu, 25 Jun 2015 09:06:56 +0200 Subject: firmware: dmi_scan: add SBMIOS entry and DMI tables Some utils, like dmidecode and smbios, need to access SMBIOS entry table area in order to get information like SMBIOS version, size, etc. Currently it's done via /dev/mem. But for situation when /dev/mem usage is disabled, the utils have to use dmi sysfs instead, which doesn't represent SMBIOS entry and adds code/delay redundancy when direct access for table is needed. So this patch creates dmi/tables and adds SMBIOS entry point to allow utils in question to work correctly without /dev/mem. Also patch adds raw dmi table to simplify dmi table processing in user space, as proposed by Jean Delvare.
