| 1103 | * The SMBus PCI Device can be activated by setting a bit in the ICH LPC |

gw.kernel@tnode.com | d7698ed | 2007-08-23 21:22:04 +0200 | [diff] [blame] | 1105 | * becomes necessary to do this tweak in two steps -- the chosen trigger |

| 1110 | * was done by SMM code, which could cause unsynchronized concurrent |
| 1111 | * accesses to the SMBus registers, with potentially bad effects. Thus you |
| 1112 | * should be very careful when adding new entries: if SMM is accessing the |
| 1113 | * Intel SMBus, this is a very good reason to leave it hidden. |

| 1115 | * Likewise, many recent laptops use ACPI for thermal management. If the |
| 1116 | * ACPI DSDT code accesses the SMBus, then Linux should not access it |
| 1117 | * natively, and keeping the SMBus hidden is the right thing to do. If you |
| 1118 | * are about to add an entry in the table below, please first disassemble |
| 1119 | * the DSDT and double-check that there is no code accessing the SMBus. |
