VII - Specifying interrupt information for devices
|
||||
===================================================
|
||||
|
||||
The device tree represents the busses and devices of a hardware
|
||||
system in a form similar to the physical bus topology of the
|
||||
hardware.
|
||||
|
||||
In addition, a logical 'interrupt tree' exists which represents the
|
||||
hierarchy and routing of interrupts in the hardware.
|
||||
|
||||
The interrupt tree model is fully described in the
|
||||
document "Open Firmware Recommended Practice: Interrupt
|
||||
Mapping Version 0.9". The document is available at:
|
||||
<http://playground.sun.com/1275/practice>.
|
||||
|
||||
1) interrupts property
|
||||
----------------------
|
||||
|
||||
Devices that generate interrupts to a single interrupt controller
|
||||
should use the conventional OF representation described in the
|
||||
OF interrupt mapping documentation.
|
||||
|
||||
Each device which generates interrupts must have an 'interrupt'
|
||||
property. The interrupt property value is an arbitrary number of
|
||||
of 'interrupt specifier' values which describe the interrupt or
|
||||
interrupts for the device.
|
||||
|
||||
The encoding of an interrupt specifier is determined by the
|
||||
interrupt domain in which the device is located in the
|
||||
interrupt tree. The root of an interrupt domain specifies in
|
||||
its #interrupt-cells property the number of 32-bit cells
|
||||
required to encode an interrupt specifier. See the OF interrupt
|
||||
mapping documentation for a detailed description of domains.
|
||||
|
||||
For example, the binding for the OpenPIC interrupt controller
|
||||
specifies an #interrupt-cells value of 2 to encode the interrupt
|
||||
number and level/sense information. All interrupt children in an
|
||||
OpenPIC interrupt domain use 2 cells per interrupt in their interrupts
|
||||
property.
|
||||
|
||||
The PCI bus binding specifies a #interrupt-cell value of 1 to encode
|
||||
which interrupt pin (INTA,INTB,INTC,INTD) is used.
|
||||
|
||||
2) interrupt-parent property
|
||||
----------------------------
|
||||
|
||||
The interrupt-parent property is specified to define an explicit
|
||||
link between a device node and its interrupt parent in
|
||||
the interrupt tree. The value of interrupt-parent is the
|
||||
phandle of the parent node.
|
||||
|
||||
If the interrupt-parent property is not defined for a node, it's
|
||||
interrupt parent is assumed to be an ancestor in the node's
|
||||
_device tree_ hierarchy.
|
||||
|
||||
3) OpenPIC Interrupt Controllers
|
||||
--------------------------------
|
||||
|
||||
OpenPIC interrupt controllers require 2 cells to encode
|
||||
interrupt information. The first cell defines the interrupt
|
||||
number. The second cell defines the sense and level
|
||||
information.
|
||||
|
||||
Sense and level information should be encoded as follows:
|
||||
|
||||
0 = low to high edge sensitive type enabled
|
||||
1 = active low level sensitive type enabled
|
||||
2 = active high level sensitive type enabled
|
||||
3 = high to low edge sensitive type enabled
|
||||
|
||||
4) ISA Interrupt Controllers
|
||||
----------------------------
|
||||
|
||||
ISA PIC interrupt controllers require 2 cells to encode
|
||||
interrupt information. The first cell defines the interrupt
|
||||
number. The second cell defines the sense and level
|
||||
information.
|
||||
|
||||
ISA PIC interrupt controllers should adhere to the ISA PIC
|
||||
encodings listed below:
|
||||
|
||||
0 = active low level sensitive type enabled
|
||||
1 = active high level sensitive type enabled
|
||||
2 = high to low edge sensitive type enabled
|
||||
3 = low to high edge sensitive type enabled

||||

||||

|

help
|
||||
Some versions of the PPC601 (the first PowerPC chip) have bugs which
|
||||
mean that extra synchronization instructions are required near
|
||||
certain instructions, typically those that make major changes to the
|
||||
CPU state. These extra instructions reduce performance slightly.
|
||||
If you say N here, these extra instructions will not be included,
|
||||
resulting in a kernel which will run faster but may not run at all
|
||||
on some systems with the PPC601 chip.
|
||||
|
||||
If in doubt, say Y here.

config TAU
|

bool "On-chip CPU temperature sensor support"
|

depends on 6xx
|
||||
help
|
||||
G3 and G4 processors have an on-chip temperature sensor called the
|
||||
'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
|
||||
temperature within 2-4 degrees Celsius. This option shows the current
|
||||
on-die temperature in /proc/cpuinfo if the cpu supports it.
|
||||
|
||||
Unfortunately, on some chip revisions, this sensor is very inaccurate
|
||||
and in many cases, does not work at all, so don't assume the cpu
|
||||
temp is actually what /proc/cpuinfo says it is.

config TAU_INT
|

bool "Interrupt driven TAU driver (DANGEROUS)"
|

depends on TAU
|
||||
---help---
|
||||
The TAU supports an interrupt driven mode which causes an interrupt
|
||||
whenever the temperature goes out of range. This is the fastest way
|
||||
to get notified the temp has exceeded a range. With this option off,
|
||||
a timer is used to re-check the temperature periodically.
|
||||
|
||||
However, on some cpus it appears that the TAU interrupt hardware
|
||||
is buggy and can cause a situation which would lead unexplained hard
|
||||
lockups.
|
||||
|
||||
Unless you are extending the TAU driver, or enjoy kernel/hardware
|
||||
debugging, leave this option off.
|
||||
|
||||
config TAU_AVERAGE
|

bool "Average high and low temp"
|

---help---
|
||||
The TAU hardware can compare the temperature to an upper and lower
|
||||
bound. The default behavior is to show both the upper and lower
|
||||
bound in /proc/cpuinfo. If the range is large, the temperature is
|
||||
either changing a lot, or the TAU hardware is broken (likely on some
|
||||
G4's). If the range is small (around 4 degrees), the temperature is
|
||||
relatively stable. If you say Y here, a single temperature value,
|
||||
halfway between the upper and lower bounds, will be reported in
|
||||
/proc/cpuinfo.
|
||||
|
||||
If in doubt, say N here.
