I don't really care about that. I just want to be able to look at and decode the values more easily. Speaking of pie in the sky, it would also be nice if I could tell it to spit out a string of binary bits instead of hex sometimes. It would be even better if I could only spit out certain bits as binary or hex. For example, let's say I want something like bits 23 through 29 of the quad word @ 0x40. # setpci binary(40.Q[32:23]) 0x40[29:23]: 0011 0101 10 Or let's say I wanted the same thing in hex: # setpci hex(40.Q[32:23]) 0x40[29:23]: 0xD6 wt -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
