2015-05-13powerpc/eeh: fix start/end/flags type in struct pci_io_addr_range{}Wei Yang1-8/+8
struct pci_io_addr_range{} stores the information of pci resources. It would be better to keep these related fields have the same type as in struct resource{}. This patch fixes the start/end/flags type in struct pci_io_addr_range{} to have the same type as in struct resource{}.

2015-03-24powerpc/eeh: Remove device_node dependencyGavin Shan1-14/+11
The patch removes struct eeh_dev::dn and the corresponding helper functions: eeh_dev_to_of_node() and of_node_to_eeh_dev(). Instead, eeh_dev_to_pdn() and pdn_to_eeh_dev() should be used to get the pdn, which might contain device_node on PowerNV platform.

2014-08-05powerpc/eeh: Replace pr_warning() with pr_warn()Gavin Shan1-3/+4
pr_warn() is equal to pr_warning(), but the former is a bit more formal according to commit fc62f2f ("kernel.h: add pr_warn for symmetry to dev_warn, netdev_warn"). The patch replaces pr_warning() with pr_warn(). Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-08-05powerpc/eeh: Refactor EEH flag accessorsGavin Shan1-1/+1
There are multiple global EEH flags. Almost each flag has its own accessor, which doesn't make sense. The patch refactors EEH flag accessors so that they look unified: eeh_add_flag(): Add EEH flag eeh_clear_flag(): Clear EEH flag eeh_has_flag(): Check if one specific flag has been set eeh_enabled(): Check if EEH functionality has been enabled Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-07-24powerpc/eeh: Remove reference to PCI deviceGavin Shan1-13/+5
We will rely on pcibios_release_device() to remove the EEH cache and unbind EEH device for the specific PCI device. So we shouldn't hold the reference to the PCI device from EEH cache and EEH device. Otherwise, pcibios_release_device() won't be called as we expected. The patch removes the reference to the PCI device in EEH core.

2013-07-01Merge tag 'v3.10' into nextBenjamin Herrenschmidt1-2/+2
Merge 3.10 in order to get some of the last minute powerpc changes, resolve conflicts and add additional fixes on top of them.
2013-07-01powerpc/eeh: Avoid build warningsGavin Shan1-1/+1
The patch is for avoiding following build warnings: The function .pnv_pci_ioda_fixup() references the function __init .eeh_init(). This is often because .pnv_pci_ioda_fixup lacks a __init The function .pnv_pci_ioda_fixup() references the function __init .eeh_addr_cache_build(). This is often because .pnv_pci_ioda_fixup lacks a __init Signed-off-by: Gavin Shan <shangw@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-07-01powerpc/eeh: Fix address catch for PowerNVGavin Shan1-1/+1
On the PowerNV platform, the EEH address cache isn't built correctly because we skipped the EEH devices without binding PE. The patch fixes that. Signed-off-by: Gavin Shan <shangw@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-06-20powerpc/eeh: Move common part to kernel directoryGavin Shan1-0/+318
The patch moves the common part of EEH core into arch/powerpc/kernel directory so that we needn't PPC_PSERIES while compiling POWERNV platform: * Move the EEH common part into arch/powerpc/kernel * Move the functions for PCI hotplug from pSeries platform to arch/powerpc/kernel/pci-hotplug.c * Move CONFIG_EEH from arch/powerpc/platforms/pseries/Kconfig to arch/powerpc/platforms/Kconfig * Adjust makefile accordingly Signed-off-by: Gavin Shan <shangw@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
