Hello,
I have some questions about device number extension.
In Linux kernel 2.6, device number will be extended from 16-bit to 32-bit. All utilities and libraries should make corresponding extension for this new feature in kernel 2.6.
I find that ?lm_sensors-2.8.1-2.4.23? considers and operates device number as 16-bit in following places:
In file kernel/chips/smbus-arp.c: 99
u16 dev_int;
"u16" is defined as unsigned short type. It seems not to correspond to device number extension.
In file kernel/chips/smbus-arp.c: 376
data->dev[newdev].dev_int = (blk[6] << 8) | blk[7];
As following, "major" should be 12-bit, and "minor" should be 20-bit.
mmmm mmmm mmmm MMMM MMMM MMMM mmmm mmmm
"M" means major device number.
"m" means minor device number.
But this expression considers both major number and minor number as 8-bit. It seems not to correspond to device number extension.
In file kernel/busses/i2c-piix4.c: 49
const unsigned short dev;
This definition seems not to correspond to device number extension.
Since I didn?t find any information about this aspect in homepage of this package, I wonder whether the latest version has completed the device number extension? If not, will it be completed in the future? And when?
Looking forward to answering.
Regards,
Zhang Jun
