 III. Technical Miscellany
 =========================
 
+Benefits of using meta-intel
+----------------------------
+
+Using meta-intel has the following benefits over a generic BSP:
+
+tune flags
+++++++++++
+intel-* MACHINEs each have different compilation flags appropriate for their
+targeted hardware sets. intel-corei7-64 has tune flags appropriate for modern
+64-bit Intel Core i microarchitecture, and includes instruction sets up to
+SSE4.2. intel-core2-32 has tune flags appropriate for legacy 32-bit Intel Core2
+microarchitecture, and includes instruction sets up to SSE3. intel-quark
+contains a subset of the intel-core2-32 instruction set, as quark does not
+support prefix locking instructions.
+
+linux-intel kernel
+++++++++++++++++++
+The linux-intel kernel is an initiative to bring better Intel(R) hardware
+support to the current LTS linux kernel. It contains a base LTS kernel with
+additional backports from upstream Intel drivers. In addition, a default kernel
+config containing most features found on Intel boards is supplied via the
+yocto-kernel-cache.
+
+graphics stack
+++++++++++++++
+Meta-intel provides the latest Intel Graphics Linux Stack drivers to support
+Intel hardware as defined by the https://01.org/linuxgraphics.
+
+Other software
+++++++++++++++
+  * intel ucode - provides the latest microcode updates for Intel processors
+
+  * thermald - which proactively controls thermal, using P-states, T-states, and
+the Intel power clamp driver.
+(https://01.org/linux-thermal-daemon/documentation/introduction-thermal-daemon)
+
+  * RMC - Runtime Machine Configuration, which allows the bootload to determine
+board and CPU information in order to set specific kernel command line
+information at startup.
