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). | |

969 | * | |
970 | * The SMBus PCI Device can be activated by setting a bit in the ICH LPC | |

d7698edc | 972 | * becomes necessary to do this tweak in two steps -- the chosen trigger |
973 | * is either the Host bridge (preferred) or on-board VGA controller. | |
9208ee82 JD |
974 | * |
975 | * Note that we used to unhide the SMBus that way on Toshiba laptops | |
976 | * (Satellite A40 and Tecra M2) but then found that the thermal management | |
977 | * was done by SMM code, which could cause unsynchronized concurrent | |
978 | * accesses to the SMBus registers, with potentially bad effects. Thus you | |
979 | * should be very careful when adding new entries: if SMM is accessing the | |
980 | * Intel SMBus, this is a very good reason to leave it hidden. | |
a99acc83 JD |
981 | * |
982 | * Likewise, many recent laptops use ACPI for thermal management. If the | |
983 | * ACPI DSDT code accesses the SMBus, then Linux should not access it | |
984 | * natively, and keeping the SMBus hidden is the right thing to do. If you | |
985 | * are about to add an entry in the table below, please first disassemble | |
986 | * the DSDT and double-check that there is no code accessing the SMBus. | |
