2013-07-24powerpc/perf: Ignore separate BHRB privilege state filter requestAnshuman Khandual1-9/+4
Completely ignore BHRB privilege state filter request as we are already configuring that with privilege state filtering attribute for the accompanying PMU event. This would help achieve cleaner user space interaction for BHRB. This patch fixes a situation like this Before patch:- ------------ ./perf record -j any -e branch-misses:k ls Error: The sys_perf_event_open() syscall returned with 95 (Operation not supported) for event (branch-misses:k). /bin/dmesg may provide additional information. No CONFIG_PERF_EVENTS=y kernel support configured? Here 'perf record' actually copies over ':k' filter request into BHRB privilege state filter config and our previous check in kernel would fail that. After patch:- ------------- ./perf record -j any -e branch-misses:k ls perf perf.data perf.data.old test-mmap-ring [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.002 MB perf.data (~102 samples)] Signed-off-by: Anshuman Khandual <khandual@linux.vnet.ibm.com> Acked-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2013-07-24powerpc/eeh: Don't use pci_dev during BAR restoreGavin Shan4-16/+91
While restoring BARs for one specific PCI device, the pci_dev instance should have been released. So it's not reliable to use the pci_dev instance on restoring BARs. However, we still need some information (e.g. PCIe capability position, header type) from the pci_dev instance. So we have to store those information to EEH device in advance.

2013-07-24powerpc/eeh: Use partial hotplug for EEH unaware driversGavin Shan7-24/+117
When EEH error happens to one specific PE, some devices with drivers supporting EEH won't except hotplug on the device. However, there might have other deivces without driver, or with driver without EEH support. For the case, we need do partial hotplug in order to make sure that the PE becomes absolutely quite during reset. Otherise, the PE reset might fail and leads to failure of error recovery. The current code doesn't handle that 'mixed' case properly, it either uses the error callbacks to the drivers, or tries hotplug, but doesn't handle a PE (EEH domain) composed of a combination of the two. The patch intends to support so-called "partial" hotplug for EEH: Before we do reset, we stop and remove those PCI devices without EEH sensitive driver. The corresponding EEH devices are not detached from its PE, but with special flag. After the reset is done, those EEH devices with the special flag will be scanned one by one.

2013-07-24powerpc/pci: Partial tree hotplug supportGavin Shan3-21/+51
When EEH error happens to one specific PE, the device drivers of its attached EEH devices (PCI devices) are checked to see the further action: reset with complete hotplug, or reset without hotplug. However, that's not enough for those PCI devices whose drivers can't support EEH, or those PCI devices without driver. So we need do so-called "partial hotplug" on basis of PCI devices. In the situation, part of PCI devices of the specific PE are unplugged and plugged again after PE reset. The patch changes pcibios_add_pci_devices() so that it can support full hotplug and so-called "partial" hotplug based on device-tree or real hardware. It's notable that pci_of_scan.c has been changed for a bit in order to support the "partial" hotplug based on dev-tree. Most of the generic code already supports that, we just need to plumb it properly on our side.

2013-07-24powerpc/eeh: Use safe list traversal when walking EEH devicesGavin Shan3-9/+9
Currently, we're trasversing the EEH devices list using list_for_each_entry(). That's not safe enough because the EEH devices might be removed from its parent PE while doing iteration.

2013-07-24powerpc/eeh: Keep PE during hotplugGavin Shan6-60/+20
When we do normal hotplug, the PE (shadow EEH structure) shouldn't be kept around. However, we need to keep it if the hotplug an artifial one caused by EEH errors recovery. Since we remove EEH device through the PCI hook pcibios_release_device(), the flag "purge_pe" passed to various functions is meaningless. So the patch removes the meaningless flag and introduce new flag "EEH_PE_KEEP" to save the PE while doing hotplug during EEH error recovery.
