From cc3a1378b4dd45d3e78dd4aeb10641b06a87d614 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Sat, 2 Feb 2008 11:32:01 -0800 Subject: Revert "PCI: PCIE ASPM support" This reverts commit 6c723d5bd89f03fc3ef627d50f89ade054d2ee3b. It caused build errors on non-x86 platforms, config file confusion, and even some boot errors on some x86-64 boxes. All around, not quite ready for prime-time :( Cc: Shaohua Li Signed-off-by: Greg Kroah-Hartman --- include/linux/aspm.h | 44 -------------------------------------------- include/linux/pci.h | 5 ----- include/linux/pci_regs.h | 8 -------- 3 files changed, 57 deletions(-) delete mode 100644 include/linux/aspm.h (limited to 'include/linux') diff --git a/include/linux/aspm.h b/include/linux/aspm.h deleted file mode 100644 index f41a69895485..000000000000 --- a/include/linux/aspm.h +++ /dev/null @@ -1,44 +0,0 @@ -/* - * aspm.h - * - * PCI Express ASPM defines and function prototypes - * - * Copyright (C) 2007 Intel Corp. - * Zhang Yanmin (yanmin.zhang@intel.com) - * Shaohua Li (shaohua.li@intel.com) - * - * For more information, please consult the following manuals (look at - * http://www.pcisig.com/ for how to get them): - * - * PCI Express Specification - */ - -#ifndef LINUX_ASPM_H -#define LINUX_ASPM_H - -#include - -#define PCIE_LINK_STATE_L0S 1 -#define PCIE_LINK_STATE_L1 2 -#define PCIE_LINK_STATE_CLKPM 4 - -#ifdef CONFIG_PCIEASPM -extern void pcie_aspm_init_link_state(struct pci_dev *pdev); -extern void pcie_aspm_exit_link_state(struct pci_dev *pdev); -extern void pcie_aspm_pm_state_change(struct pci_dev *pdev); -extern void pci_disable_link_state(struct pci_dev *pdev, int state); -#else -#define pcie_aspm_init_link_state(pdev) do {} while (0) -#define pcie_aspm_exit_link_state(pdev) do {} while (0) -#define pcie_aspm_pm_state_change(pdev) do {} while (0) -#define pci_disable_link_state(pdev, state) do {} while (0) -#endif - -#ifdef CONFIG_PCIEASPM_DEBUG /* this depends on CONFIG_PCIEASPM */ -extern void pcie_aspm_create_sysfs_dev_files(struct pci_dev *pdev); -extern void pcie_aspm_remove_sysfs_dev_files(struct pci_dev *pdev); -#else -#define pcie_aspm_create_sysfs_dev_files(pdev) do {} while (0) -#define pcie_aspm_remove_sysfs_dev_files(pdev) do {} while (0) -#endif -#endif /* LINUX_ASPM_H */ diff --git a/include/linux/pci.h b/include/linux/pci.h index 4f96f1d94ac4..cee75c0ff6e7 100644 --- a/include/linux/pci.h +++ b/include/linux/pci.h @@ -128,7 +128,6 @@ struct pci_cap_saved_state { u32 data[0]; }; -struct pcie_link_state; /* * The pci_dev structure is used to describe PCI devices. */ @@ -164,10 +163,6 @@ struct pci_dev { this is D0-D3, D0 being fully functional, and D3 being off. */ -#ifdef CONFIG_PCIEASPM - struct pcie_link_state *link_state; /* ASPM link state. */ -#endif - pci_channel_state_t error_state; /* current connectivity state */ struct device dev; /* Generic device interface */ diff --git a/include/linux/pci_regs.h b/include/linux/pci_regs.h index c0c1223c9194..c1914a8b94a9 100644 --- a/include/linux/pci_regs.h +++ b/include/linux/pci_regs.h @@ -395,17 +395,9 @@ #define PCI_EXP_DEVSTA_AUXPD 0x10 /* AUX Power Detected */ #define PCI_EXP_DEVSTA_TRPND 0x20 /* Transactions Pending */ #define PCI_EXP_LNKCAP 12 /* Link Capabilities */ -#define PCI_EXP_LNKCAP_ASPMS 0xc00 /* ASPM Support */ -#define PCI_EXP_LNKCAP_L0SEL 0x7000 /* L0s Exit Latency */ -#define PCI_EXP_LNKCAP_L1EL 0x38000 /* L1 Exit Latency */ -#define PCI_EXP_LNKCAP_CLKPM 0x40000 /* L1 Clock Power Management */ #define PCI_EXP_LNKCTL 16 /* Link Control */ -#define PCI_EXP_LNKCTL_RL 0x20 /* Retrain Link */ -#define PCI_EXP_LNKCTL_CCC 0x40 /* Common Clock COnfiguration */ #define PCI_EXP_LNKCTL_CLKREQ_EN 0x100 /* Enable clkreq */ #define PCI_EXP_LNKSTA 18 /* Link Status */ -#define PCI_EXP_LNKSTA_LT 0x800 /* Link Training */ -#define PCI_EXP_LNKSTA_SLC 0x1000 /* Slot Clock Configuration */ #define PCI_EXP_SLTCAP 20 /* Slot Capabilities */ #define PCI_EXP_SLTCTL 24 /* Slot Control */ #define PCI_EXP_SLTSTA 26 /* Slot Status */ -- cgit v1.2.3
