From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jeff Kirsher Subject: [net-2.6 PATCH] igb: remove ASPM L0s workaround Date: Sat, 14 Mar 2009 18:38:52 -0700 Message-ID: <20090315013846.23201.71757.stgit@lost.foo-projects.org> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Cc: netdev@vger.kernel.org, gospo@redhat.com, stable@kernel.org, Alexander Duyck , Jeff Kirsher To: davem@davemloft.net Return-path: Received: from qmta07.emeryville.ca.mail.comcast.net ([76.96.30.64]:60282 "EHLO QMTA07.emeryville.ca.mail.comcast.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752137AbZCOBjO (ORCPT ); Sat, 14 Mar 2009 21:39:14 -0400 Sender: netdev-owner@vger.kernel.org List-ID: From: Alexander Duyck The L0s workaround should be moved into a pci quirk and so it is not necessary in the driver. This update removes the L0s workaround from the igb driver. This was the second half of the PCI quirk patch that Matthew Wilcox did not pick up when he picked up the quirk patch. This patch applies to the net-2.6 tree. :) Signed-off-by: Alexander Duyck Signed-off-by: Jeff Kirsher --- drivers/net/igb/igb_main.c | 26 ++------------------------ 1 files changed, 2 insertions(+), 24 deletions(-) diff --git a/drivers/net/igb/igb_main.c b/drivers/net/igb/igb_main.c index a50db53..9dd13ad 100644 --- a/drivers/net/igb/igb_main.c +++ b/drivers/net/igb/igb_main.c @@ -1023,11 +1023,10 @@ static int __devinit igb_probe(struct pci_dev *pdev, struct net_device *netdev; struct igb_adapter *adapter; struct e1000_hw *hw; - struct pci_dev *us_dev; const struct e1000_info *ei = igb_info_tbl[ent->driver_data]; unsigned long mmio_start, mmio_len; - int i, err, pci_using_dac, pos; - u16 eeprom_data = 0, state = 0; + int i, err, pci_using_dac; + u16 eeprom_data = 0; u16 eeprom_apme_mask = IGB_EEPROM_APME; u32 part_num; int bars, need_ioport; @@ -1062,27 +1061,6 @@ static int __devinit igb_probe(struct pci_dev *pdev, } } - /* 82575 requires that the pci-e link partner disable the L0s state */ - switch (pdev->device) { - case E1000_DEV_ID_82575EB_COPPER: - case E1000_DEV_ID_82575EB_FIBER_SERDES: - case E1000_DEV_ID_82575GB_QUAD_COPPER: - us_dev = pdev->bus->self; - pos = pci_find_capability(us_dev, PCI_CAP_ID_EXP); - if (pos) { - pci_read_config_word(us_dev, pos + PCI_EXP_LNKCTL, - &state); - state &= ~PCIE_LINK_STATE_L0S; - pci_write_config_word(us_dev, pos + PCI_EXP_LNKCTL, - state); - dev_info(&pdev->dev, - "Disabling ASPM L0s upstream switch port %s\n", - pci_name(us_dev)); - } - default: - break; - } - err = pci_request_selected_regions(pdev, bars, igb_driver_name); if (err) goto err_pci_reg;
