2013-05-25PCI: Unset resource if initial BAR value is invalidKevin Hao1-1/+21
The initial BAR value in the following example is invalid: pci_bus 0000:00: root bus resource [mem 0xa0000000-0xbfffffff] (bus address [0xe0000000-0xffffffff]) pci 0000:01:00.0: reg 10: initial BAR value: 0xa0000000 pci 0000:01:00.0: reg 10: [mem 0xa0000000-0xa000007f 64bit] bus_to_resource(0xa0000000) yields 0xa0000000 because there's no host bridge window whose bus address range contains 0xa0000000. But CPU accesses to 0xa0000000 appear on the bus at 0xe0000000, so they will not be claimed if the BAR contains 0xa0000000. If we find a BAR where resource_to_bus(bus_to_resource(A)) != A, we can work around this problem by reassigning the BAR.

2013-05-21PCI/ASPM: Warn when driver asks to disable ASPM, but we can't do itBjorn Helgaas1-3/+13
Some devices have hardware problems related to using ASPM. Drivers for these devices use pci_disable_link_state() to prevent their device from entering L0s or L1. But on platforms where the OS doesn't have permission to manage ASPM, pci_disable_link_state() doesn't actually disable ASPM. Windows has a similar mechanism ("PciASPMOptOut"), and when the OS doesn't have control of ASPM, it doesn't actually disable ASPM either. This patch just adds a warning in dmesg about the fact that pci_disable_link_state() is doing nothing.

2013-05-10[SCSI] sas: unify the pointlessly separated enums sas_dev_type and sas_device_typeJames Bottomley24-165/+160
These enums have been separate since the dawn of SAS, mainly because the latter is a procotol only enum and the former includes additional state for libsas. The dichotomy causes endless confusion about which one you should use where and leads to pointless warnings like this: drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo': drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare] Fix by eliminating one of them. The one kept is effectively the sas.h one, but call it sas_device_type and make sure the enums are all properly namespaced with the SAS_ prefix.
