Although originally developed first for 32-bit x86-based PCs (386 or higher),
today Linux also runs on (at least) the Compaq Alpha AXP, Sun SPARC and
UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH,

Cris, Xtensa, AVR32 and Renesas M32R architectures.
Linux is easily portable to most general-purpose 32- or 64-bit architectures
as long as they have a paged memory management unit (PMMU) and a port of the
GNU C compiler (gcc) (part of The GNU Compiler Collection, GCC). Linux has
also been ported to a number of architectures without a PMMU, although
functionality is then obviously somewhat limited.
Linux has also been ported to itself. You can now run the kernel as a
userspace application - this is called UserMode Linux (UML).

Select this option if you want to disable continuous timer ticks
and have them programmed to occur as required. This option saves
power as the system can remain in idle state for longer.
By default dynamic tick is disabled during the boot, and can be
manually enabled with:
echo 1 > /sys/devices/system/timer/timer0/dyn_tick
Alternatively, if you want dynamic tick automatically enabled
during boot, pass "dyntick=enable" via the kernel command string.
Please note that dynamic tick may affect the accuracy of
timekeeping on some platforms depending on the implementation.

/*
* A brief note about the reasons for this API as it stands.
*
* For starters, the old ISA DMA API didn't work for us for a number of
* reasons, for one, the vast majority of channels on the SH DMAC are
* dual-address mode only, and both the new and the old DMA APIs are after the
* concept of managing a DMA buffer, which doesn't overly fit this model very
* well. In addition to which, the new API is largely geared at IOMMUs and
* GARTs, and doesn't even support the channel notion very well.
*
* The other thing that's a marginal issue, is the sheer number of random DMA
* engines that are present (ie, in boards like the Dreamcast), some of which
* cascade off of the SH DMAC, and others do not. As such, there was a real
* need for a scalable subsystem that could deal with both single and
* dual-address mode usage, in addition to interoperating with cascaded DMACs.
*
* There really isn't any reason why this needs to be SH specific, though I'm
* not aware of too many other processors (with the exception of some MIPS)
* that have the same concept of a dual address mode, or any real desire to
* actually make use of the DMAC even if such a subsystem were exposed
* elsewhere.
*
* The idea for this was derived from the ARM port, which acted as an excellent
* reference when trying to address these issues.
*
* It should also be noted that the decision to add Yet Another DMA API(tm) to
* the kernel wasn't made easily, and was only decided upon after conferring
* with jejb with regards to the state of the old and new APIs as they applied
* to these circumstances. Philip Blundell was also a great help in figuring
* out some single-address mode DMA semantics that were otherwise rather
* confusing.
