Copy was done using the following simple script:
set -e
SPARC64="h display7seg.h envctrl.h psrcompat.h pstate.h uctx.h utrap.h watchdog.h"
for FILE in ${SPARC64}; do
if [ -f asm-sparc/$FILE ]; then
echo $FILE exist in asm-sparc
fi
cat asm-sparc64/$FILE > asm-sparc/$FILE
printf "#include <asm-sparc/$FILE>\n" > asm-sparc64/$FILE
done
The name of the copied files are added to asm-sparc/Kbuild
to keep "make headers_check" functional.

/* Application note:
|
|
*
|
|
* The driver supports 4 operations: open(), close(), ioctl(), read()
|
|
* The device name is /dev/envctrl.
|
|
* Below is sample usage:
|
|
*
|
|
* fd = open("/dev/envtrl", O_RDONLY);
|
|
* if (ioctl(fd, ENVCTRL_READ_SHUTDOWN_TEMPERATURE, 0) < 0)
|
|
* printf("error\n");
|
|
* ret = read(fd, buf, 10);
|
|
* close(fd);
|
|
*
|
|
* Notice in the case of cpu voltage and temperature, the default is
|
|
* cpu0. If we need to know the info of cpu1, cpu2, cpu3, we need to
|
|
* pass in cpu number in ioctl() last parameter. For example, to
|
|
* get the voltage of cpu2:
|
|
*
|
|
* ioctlbuf[0] = 2;
|
|
* if (ioctl(fd, ENVCTRL_READ_CPU_VOLTAGE, ioctlbuf) < 0)
|
|
* printf("error\n");
|
|
* ret = read(fd, buf, 10);
|
|
*
|
|
* All the return values are in ascii. So check read return value
|
|
* and do appropriate conversions in your application.
