2 | * This file contains work-arounds for many known PCI hardware | |
3 | * bugs. Devices present only on certain architectures (host | |
4 | * bridges et cetera) should be handled in arch-specific code. | |
5 | * | |
6 | * Note: any quirks for hotpluggable devices must _NOT_ be declared __init. | |

10 | * Init/reset quirks for USB host controllers should be in the |
11 | * USB quirks file, where their drivers can access reuse it. | |
12 | * | |
1da177e4 LT |
13 | * The bridge optimization stuff has been removed. If you really |
14 | * have a silly BIOS which is unable to set your host bridge right, | |
15 | * use the PowerTweak utility (see http://powertweak.sourceforge.net). | |

1069 | * On ASUS P4B boards, the SMBus PCI Device within the ICH2/4 southbridge | |

1071 | * users to be irritated by just another PCI Device in the Win98 device | |
1072 | * manager. (see the file prog/hotplug/README.p4b in the lm_sensors | |
1073 | * package 2.7.0 for details) | |
1074 | * | |
1075 | * The SMBus PCI Device can be activated by setting a bit in the ICH LPC | |
1076 | * bridge. Unfortunately, this device has no subvendor/subdevice ID. So it | |
d7698edc | 1077 | * becomes necessary to do this tweak in two steps -- the chosen trigger |
1078 | * is either the Host bridge (preferred) or on-board VGA controller. | |
9208ee82 JD |
1079 | * |
1080 | * Note that we used to unhide the SMBus that way on Toshiba laptops | |
1081 | * (Satellite A40 and Tecra M2) but then found that the thermal management | |
1082 | * was done by SMM code, which could cause unsynchronized concurrent | |
1083 | * accesses to the SMBus registers, with potentially bad effects. Thus you | |
1084 | * should be very careful when adding new entries: if SMM is accessing the | |
1085 | * Intel SMBus, this is a very good reason to leave it hidden. | |
a99acc83 JD |
1086 | * |
1087 | * Likewise, many recent laptops use ACPI for thermal management. If the | |
1088 | * ACPI DSDT code accesses the SMBus, then Linux should not access it | |
1089 | * natively, and keeping the SMBus hidden is the right thing to do. If you | |
1090 | * are about to add an entry in the table below, please first disassemble | |
1091 | * the DSDT and double-check that there is no code accessing the SMBus. | |
