powerpc/eeh: Fix pr_debug()s in eeh_cache.c

2016-07-08T12:09:50Z

eeh_cache.c doesn't build cleanly with -DDEBUG when CONFIG_PHYS_ADDR_T_64BIT is set, as a couple of pr_debug()s use "%lx" for resource_size_t parameters. Use "%pap" instead, as it's the correct format specifier for types deriving from phys_addr_t. Signed-off-by: Andrew Donnellan Reviewed-by: Gavin Shan Signed-off-by: Michael Ellerman

powerpc/eeh: Cache normal BARs, not windows or IOV BARs

2016-03-08T22:58:17Z

This restricts the EEH address cache to use only the first 7 BARs. This makes __eeh_addr_cache_insert_dev() ignore PCI bridge window and IOV BARs. As the result of this change, eeh_addr_cache_get_dev() will return VFs from VF's resource addresses instead of parent PFs. This also removes PCI bridge check as we limit __eeh_addr_cache_insert_dev() to 7 BARs and this effectively excludes PCI bridges from being cached.

powerpc/eeh: fix start/end/flags type in struct pci_io_addr_range{}

2015-05-13T04:00:07Z

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{}. Signed-off-by: Wei Yang Acked-by: Gavin Shan Signed-off-by: Michael Ellerman

powerpc/eeh: Remove device_node dependency

2015-03-24T02:15:53Z

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. Signed-off-by: Gavin Shan Signed-off-by: Benjamin Herrenschmidt

powerpc/eeh: Replace pr_warning() with pr_warn()

2014-08-05T05:41:34Z

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 Signed-off-by: Benjamin Herrenschmidt

powerpc/eeh: Refactor EEH flag accessors

2014-08-05T05:41:21Z

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 Signed-off-by: Benjamin Herrenschmidt

powerpc/eeh: Remove reference to PCI device

2013-07-24T04:18:46Z

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. Signed-off-by: Gavin Shan Signed-off-by: Benjamin Herrenschmidt

Merge tag 'v3.10' into next

2013-07-01T07:57:25Z

Merge 3.10 in order to get some of the last minute powerpc changes, resolve conflicts and add additional fixes on top of them.

powerpc/eeh: Avoid build warnings

2013-07-01T01:10:33Z

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 Signed-off-by: Benjamin Herrenschmidt

powerpc/eeh: Fix address catch for PowerNV

2013-07-01T01:10:32Z

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 Signed-off-by: Benjamin Herrenschmidt
