2008-07-28PCI: add D3 power state avoidance quirkAlan Cox
Libata has some hacks to deal with certain controllers going silly in D3 state. The right way to handle this is to keep a PCI device flag for such devices. That can then be generalised for no ATA devices with power problems. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2008-07-02PCI: acpiphp: cleanup notify handler on all root bridgesAlex Chiang
During the development of the physical PCI slot patch series, Gary Hade kept on reporting strange oopses due to interactions between pci_slot and acpiphp. http://lkml.org/lkml/2007/11/28/319 find_root_bridges() unconditionally installs handle_hotplug_event_bridge() as an ACPI_SYSTEM_NOTIFY handler for all root bridges. However, during module cleanup, remove_bridge() will only remove the notify handler iff the root bridge had a hot-pluggable slot directly underneath. That is: root bridge -> hotplug slot But, if the topology looks like either of the following: root bridge -> non-hotplug slot root bridge -> p2p bridge -> hotplug slot Then we currently do not remove the notify handler from that root bridge. This can cause a kernel oops if we modprobe acpiphp later and it gets loaded somewhere else in memory. If the root bridge then receives a hotplug event, it will then attempt to call a stale, non-existent notify handler and we blow up. Much thanks goes to Gary Hade for his persistent debugging efforts.

2008-07-02PCI: Limit VPD read/write lengths for Broadcom 5706, 5708, 5709 rev.Benjamin Li
For Broadcom 5706, 5708, 5709 rev. A nics, any read beyond the VPD end tag will hang the device. This problem was initially observed when a vpd entry was created in sysfs ('/sys/bus/pci/devices/<id>/vpd'). A read to this sysfs entry will dump 32k of data. Reading a full 32k will cause an access beyond the VPD end tag causing the device to hang. Once the device is hung, the bnx2 driver will not be able to reset the device. We believe that it is legal to read beyond the end tag and therefore the solution is to limit the read/write length. A majority of this patch is from Matthew Wilcox who gave code for reworking the PCI vpd size information. A PCI quirk added for the Broadcom NIC's to limit the read/write's.

2008-06-27pciehp: remove needless command completed interrupt settingKenji Kaneshige
Currently, pciehp driver enables command completed interrupt as follows. (1) Don't enable at initialization. (2) Enable command completed interrupt whenever pciehp issues a command, if the command doesn't attempt to disable the interrupt. (3) Disable command completed interrupt at driver unloading. Once we enable command completed interrupt, we don't need to re-enable it for every command. So we can simplify above steps as follows: (1) Enable command completed interrupt at initialization. (2) No special sequence for command completed interrupt. (3) Disable command completed interrupt at driver unloading.

2008-06-27pciehp: fix interrupt initializationKenji Kaneshige
Current pciehp driver's intialization sequence is as follows: (1) initialize controller data structure (2) install interrupt handler (3) enable software notification (4) initialize controller specific slot data structure (5) initialize generic slot data structure and register it to pci hotplug core The interrupt handler of pciehp assumes that controller specific slot data structure is already initialized. However, it is installed at (2) before initializing controller specific slot data structure at (4). Because of this, pciehp driver cannot handle the following cases properly. - If devices that shares IRQ with pciehp raise interrupts between (2) and (4). - If hotplug events (e.g. MRL open) happen between (3) and (4). We already have a workaround for this problem ("pciehp: fix NULL dereference in interrupt handler: dbd79aed1aea2bece0bf43cc2ff3b2f9baf48a08). But we still need fundamental fix. This patch fix the problem by changing the initilization sequence as follows: (1) initialize controller data structure (2) initialize controller specific slot data structure (3) install interrupt handler (4) enable software notification (5) initialize generic slot data structure and register it to pci hotplug core Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Acked-by: Alex Chiang <achiang@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

Convert printks to use dev_printk(). I converted pr_debug() to dev_dbg(). Both use KERN_DEBUG and are enabled only when DEBUG is defined. I converted printk(KERN_DEBUG) to dev_printk(KERN_DEBUG), not to dev_dbg(), because dev_dbg() is only enabled when DEBUG is defined. I converted DBG(KERN_INFO) (only in setup-bus.c) to dev_info(). The DBG() name makes it sound like debug, but it's been enabled forever, so dev_info() preserves the previous behavior. I tried to make the resource assignment formats more consistent, e.g., "BAR %d: got res [%#llx-%#llx] bus [%#llx-%#llx] flags %#lx\n" instead of sometimes using "start-end" and sometimes using "size@start".
