Hello folks,
I was looking at why I can't load the Intel RNG driver (or why it doesn't load automatically) and it just so happens I have both the mobile and non-mobile ICH9 chipset. Looking at the driver I noticed:
/* BAM, CAM, DBM, FBM, GxM { PCI_DEVICE(0x8086, 0x2448) }, */ /* BA, CA, DB, Ex, 6300, Fx, 631x/632x, Gx { PCI_DEVICE(0x8086, 0x244e) }, */
IDs from both machines: 00:1e.0 PCI bridge [0604]: Intel Corporation 82801 Mobile PCI Bridge [8086:2448] (rev 93) 00:1e.0 PCI bridge [0604]: Intel Corporation 82801 PCI Bridge [8086:244e] (rev 92) I saw a thread from 2006 explaining the 50% chance there's no RNG (but these days all modern chipsets should have an RNG) and I know this chipset I have does have an RNG so I'd like to use the HW random generator vs software.
Do we need to revisit this? Even if I try to force it to load it still fails:
# modprobe intel_rng no_fwh_detect=-1 or =1 modprobe: ERROR: could not insert 'intel_rng': No such device
Thanks, Shawn
