INTERNAL KERNEL ABI FOR FR-V ARCH
=================================
The internal FRV kernel ABI is not quite the same as the userspace ABI. A number of the registers
are used for special purposed, and the ABI is not consistent between modules vs core, and MMU vs
no-MMU.
This partly stems from the fact that FRV CPUs do not have a separate supervisor stack pointer, and
most of them do not have any scratch registers, thus requiring at least one general purpose
register to be clobbered in such an event. Also, within the kernel core, it is possible to simply
jump or call directly between functions using a relative offset. This cannot be extended to modules
for the displacement is likely to be too far. Thus in modules the address of a function to call
must be calculated in a register and then used, requiring two extra instructions.

VIRTUAL INTERRUPT HANDLING
==========================
Because accesses to the PSR is so slow, and to disable interrupts we have to access it twice (once
to read and once to write), we don't actually disable interrupts at all if we don't have to. What
we do instead is use the ICC2 condition code flags to note virtual disablement, such that if we
then do take an interrupt, we note the flag, really disable interrupts, set another flag and resume
execution at the point the interrupt happened. Setting condition flags as a side effect of an
arithmetic or logical instruction is really fast. This use of the ICC2 only occurs within the

Setting condition flags as a side effect of an arithmetic or logical
instruction is really fast. This use of the ICC2 only occurs within the
kernel - it does not affect userspace.
The flags we use are:

Set to virtually disable interrupts, clear when interrupts are virtually enabled. Can be
modified by logical instructions without affecting the Carry flag.

INTRODUCTION:
STMicroelectronics produces the STV0680B chip, which comes in two
types, -001 and -003. The -003 version allows the recording and downloading
of sound clips from the camera, and allows a flash attachment. Otherwise,
it uses the same commands as the -001 version. Both versions support a
variety of SDRAM sizes and sensors, allowing for a maximum of 26 VGA or 20
CIF pictures. The STV0680 supports either a serial or a usb interface, and

MODULE OPTIONS:
When the driver is compiled as a module, you can set a "swapRGB=1"
option, if necessary, for those applications that require it
(such as xawtv). However, the driver should detect and set this
option, if necessary, for those applications that require it
(such as xawtv). However, the driver should detect and set this
automatically, so this option should not normally be used.
KNOWN PROBLEMS:
The driver seems to work better with the usb-ohci than the usb-uhci host
