Hello LKML, This is a preliminary implementation of the PTM support driver. This driver has only been tested against a virtual PCI bus since there are no known endpoints utilizing it yet. Please CC me as I am not subscribed to the list. Thanks. Changes since v1: * Moved register constants to pci_regs.h * Use pci_dev to hold PTM status * PTM initialization now done top-down hierarchy wise. Changes since v2: * Added missing void return in the pci_ptm_init inline stub. Changes since v3: * Clearing CONFIG_PCIE_PTM now completely prevents the driver from being built. * Renamed pci_*_ptm_sysfs to pcie_ptm_*_sysfs_dev_files for consistency. * Removed useless prototypes. * Driver no longer checks PTM capability version * PCI_EXT_CAP_ID_MAX updated to include PTM (0x1F) Changes since v4: * Using pci=noptm kernel parameter now disables ptm activation like other pci features. * Module param to disable ptm driver at runtime removed. * Sysfs file entries removed.
