Our new imaginary board will also have to tie into the machvec in order for it
to be of any use. Currently the machvec is slowly on its way out, but is still
required for the time being. As such, let us take a look at what needs to be
done for the machvec assignment.
to be of any use.
machvec functions fall into a number of categories:
- I/O functions to IO memory (inb etc) and PCI/main memory (readb etc).
- I/O remapping functions (ioremap etc)
- some initialisation functions
- a 'heartbeat' function
- some miscellaneous flags
The tree can be built in two ways:
- as a fully generic build. All drivers are linked in, and all functions
go through the machvec
- as a machine specific build. In this case only the required drivers
will be linked in, and some macros may be redefined to not go through
the machvec where performance is important (in particular IO functions).
There are three ways in which IO can be performed:
- none at all. This is really only useful for the 'unknown' machine type,
which us designed to run on a machine about which we know nothing, and
so all all IO instructions do nothing.
- fully custom. In this case all IO functions go to a machine specific
set of functions which can do what they like
- a generic set of functions. These will cope with most situations,
and rely on a single function, mv_port2addr, which is called through the
machine vector, and converts an IO address into a memory address, which
can be read from/written to directly.
Thus adding a new machine involves the following steps (I will assume I am
adding a machine called vapor):
- add a new file include/asm-sh/vapor/io.h which contains prototypes for
- I/O mapping functions (ioport_map, ioport_unmap, etc).
- a 'heartbeat' function.
- PCI and IRQ initialization routines.
- Consistent allocators (for boards that need special allocators,
particularly for allocating out of some board-specific SRAM for DMA
handles).
There are machvec functions added and removed over time, so always be sure to
consult include/asm-sh/machvec.h for the current state of the machvec.
The kernel will automatically wrap in generic routines for undefined function
pointers in the machvec at boot time, as machvec functions are referenced
unconditionally throughout most of the tree. Some boards have incredibly
sparse machvecs (such as the dreamcast and sh03), whereas others must define
virtually everything (rts7751r2d).
Adding a new machine is relatively trivial (using vapor as an example):
If the board-specific definitions are quite minimalistic, as is the case for
the vast majority of boards, simply having a single board-specific header is
sufficient.
- add a new file include/asm-sh/vapor.h which contains prototypes for
any machine specific IO functions prefixed with the machine name, for
example vapor_inb. These will be needed when filling out the machine
vector.
This is the minimum that is required, however there are ample
opportunities to optimise this. In particular, by making the prototypes
inline function definitions, it is possible to inline the function when
building machine specific versions. Note that the machine vector
functions will still be needed, so that a module built for a generic
setup can be loaded.
- add a new file arch/sh/boards/vapor/mach.c. This contains the definition
of the machine vector. When building the machine specific version, this
will be the real machine vector (via an alias), while in the generic
version is used to initialise the machine vector, and then freed, by
making it initdata. This should be defined as:
struct sh_machine_vector mv_vapor __initmv = {
.mv_name = "vapor",
}
ALIAS_MV(vapor)
- finally add a file arch/sh/boards/vapor/io.c, which contains
definitions of the machine specific io functions.
A note about initialisation functions. Three initialisation functions are
provided in the machine vector:
- mv_arch_init - called very early on from setup_arch
- mv_init_irq - called from init_IRQ, after the generic SH interrupt
initialisation
- mv_init_pci - currently not used
Any other remaining functions which need to be called at start up can be
added to the list using the __initcalls macro (or module_init if the code
can be built as a module). Many generic drivers probe to see if the device
they are targeting is present, however this may not always be appropriate,
so a flag can be added to the machine vector which will be set on those
machines which have the hardware in question, reducing the probe to a
single conditional.
Note that these prototypes are generated automatically by setting
__IO_PREFIX to something sensible. A typical example would be:
#define __IO_PREFIX vapor
#include <asm/io_generic.h>
somewhere in the board-specific header. Any boards being ported that still
have a legacy io.h should remove it entirely and switch to the new model.
- Add machine vector definitions to the board's setup.c. At a bare minimum,
this must be defined as something like:
struct sh_machine_vector mv_vapor __initmv = {
.mv_name = "vapor",
};
ALIAS_MV(vapor)
- finally add a file arch/sh/boards/vapor/io.c, which contains definitions of
the machine specific io functions (if there are enough to warrant it).

Notes on register bank usage in the kernel
==========================================
Introduction
------------
The SH-3 and SH-4 CPU families traditionally include a single partial register
bank (selected by SR.RB, only r0 ... r7 are banked), whereas other families
may have more full-featured banking or simply no such capabilities at all.
SR.RB banking
-------------
In the case of this type of banking, banked registers are mapped directly to
r0 ... r7 if SR.RB is set to the bank we are interested in, otherwise ldc/stc
can still be used to reference the banked registers (as r0_bank ... r7_bank)
when in the context of another bank. The developer must keep the SR.RB value
in mind when writing code that utilizes these banked registers, for obvious
reasons. Userspace is also not able to poke at the bank1 values, so these can
be used rather effectively as scratch registers by the kernel.
Presently the kernel uses several of these registers.
- r0_bank, r1_bank (referenced as k0 and k1, used for scratch
registers when doing exception handling).
- r2_bank (used to track the EXPEVT/INTEVT code)
- Used by do_IRQ() and friends for doing irq mapping based off
of the interrupt exception vector jump table offset
- r6_bank (global interrupt mask)
- The SR.IMASK interrupt handler makes use of this to set the
interrupt priority level (used by local_irq_enable())
- r7_bank (current)
