2015-04-11powerpc: move find_and_init_phbs() to pSeries specific codeDaniel Axtens1-47/+0
Previously, find_and_init_phbs() was used in both PowerNV and pSeries setup. However, since RTAS support has been dropped from PowerNV, we can move it into a platform-specific file. Signed-off-by: Daniel Axtens <dja@axtens.net> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2015-03-24powerpc/eeh: Remove device_node dependencyGavin Shan1-1/+1
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.

2014-10-15powerpc/pseries: Drop config requests in EEH accessorsGavin Shan1-19/+11
The pSeires EEH config accessors rely on rtas_{read, write}_config() and the condition to check if the PE's config space is blocked should be moved to those 2 functions so that config requests from kernel, userland, EEH core can be dropped to avoid recursive EEH error if necessary.

2014-10-15powerpc/eeh: Rename flag EEH_PE_RESET to EEH_PE_CFG_BLOCKEDGavin Shan1-2/+2
The flag EEH_PE_RESET indicates blocking config space of the PE during reset time. We potentially need block PE's config space other than reset time. So it's reasonable to replace it with EEH_PE_CFG_BLOCKED to indicate its usage. There are no substantial code or logic changes in this patch.

2014-04-28powerpc/eeh: Block PCI-CFG access during PE resetGavin Shan1-16/+50
We've observed multiple PE reset failures because of PCI-CFG access during that period. Potentially, some device drivers can't support EEH very well and they can't put the device to motionless state before PE reset. So those device drivers might produce PCI-CFG accesses during PE reset. Also, we could have PCI-CFG access from user space (e.g. "lspci"). Since access to frozen PE should return 0xFF's, we can block PCI-CFG access during the period of PE reset so that we won't get recrusive EEH errors. The patch adds flag EEH_PE_RESET, which is kept during PE reset. The PowerNV/pSeries PCI-CFG accessors reuse the flag to block PCI-CFG accordingly.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers.

2012-09-10powerpc/eeh: Trace eeh device from I/O cacheGavin Shan1-1/+1
The idea comes from Benjamin Herrenschmidt. The eeh cache helps fetching the pci device according to the given I/O address. Since the eeh cache is serving for eeh, it's reasonable for eeh cache to trace eeh device except pci device. The patch make eeh cache to trace eeh device. Also, the major eeh entry function eeh_dn_check_failure has been renamed to eeh_dev_check_failure since it will take eeh device as input parameter.

2012-09-10powerpc/eeh: Move EEH initialization aroundGavin Shan1-3/+0
Currently, we have 3 phases for EEH initialization on pSeries platform. All of them are done through builtin functions: platform initialization, EEH device creation, and EEH subsystem enablement. All of them are done no later than ppc_md.setup_arch. That means that the slab/slub isn't ready yet, so we have to allocate memory chunks on basis of PAGE_SIZE for those dynamically created EEH devices. That's pretty expensive. In order to utilize slab/slub for memory allocation, we have to move the EEH initialization functions around, but all of them should be called after slab is ready.

2012-03-09powerpc/eeh: Introduce EEH deviceGavin Shan1-0/+3
Original EEH implementation depends on struct pci_dn heavily. However, EEH shouldn't depend on that actually because EEH needn't share much information with other PCI components. That's to say, EEH should have worked independently. The patch introduces struct eeh_dev so that EEH core components needn't be working based on struct pci_dn in future. Also, struct pci_dn, struct eeh_dev instances are created in dynamic fasion and the binding with EEH device, OF node, PCI device is implemented as well. The EEH devices are created after PHBs are detected and initialized, but PCI emunation hasn't started yet. Apart from that, PHB might be created dynamically through DLPAR component and the EEH devices should be creatd as well. Another case might be OF node is created dynamically by DR (Dynamic Reconfiguration), which has been defined by PAPR. For those OF nodes created by DR, EEH devices should be also created accordingly. The binding between EEH device and OF node is done while the EEH device is initially created. The binding between EEH device and PCI device should be done after PCI emunation is done. Besides, PCI hotplug also needs the binding so that the EEH devices could be traced from the newly coming PCI buses or PCI devices.

2007-06-14[POWERPC] Rewrite IO allocation & mapping on powerpc64Benjamin Herrenschmidt1-5/+2
This rewrites pretty much from scratch the handling of MMIO and PIO space allocations on powerpc64. The main goals are: - Get rid of imalloc and use more common code where possible - Simplify the current mess so that PIO space is allocated and mapped in a single place for PCI bridges - Handle allocation constraints of PIO for all bridges including hot plugged ones within the 2GB space reserved for IO ports, so that devices on hotplugged busses will now work with drivers that assume IO ports fit in an int. - Cleanup and separate tracking of the ISA space in the reserved low 64K of IO space. No ISA -> Nothing mapped there. I booted a cell blade with IDE on PIO and MMIO and a dual G5 so far, that's it :-) With this patch, all allocations are done using the code in mm/vmalloc.c, though we use the low level __get_vm_area with explicit start/stop constraints in order to manage separate areas for vmalloc/vmap, ioremap, and PCI IOs. This greatly simplifies a lot of things, as you can see in the diffstat of that patch :-) A new pair of functions pcibios_map/unmap_io_space() now replace all of the previous code that used to manipulate PCI IOs space. The allocation is done at mapping time, which is now called from scan_phb's, just before the devices are probed (instead of after, which is by itself a bug fix). The only other caller is the PCI hotplug code for hot adding PCI-PCI bridges (slots). imalloc is gone, as is the "sub-allocation" thing, but I do beleive that hotplug should still work in the sense that the space allocation is always done by the PHB, but if you unmap a child bus of this PHB (which seems to be possible), then the code should properly tear down all the HPTE mappings for that area of the PHB allocated IO space. I now always reserve the first 64K of IO space for the bridge with the ISA bus on it. I have moved the code for tracking ISA in a separate file which should also make it smarter if we ever are capable of hot unplugging or re-plugging an ISA bridge. This should have a side effect on platforms like powermac where VGA IOs will no longer work. This is done on purpose though as they would have worked semi-randomly before. The idea at this point is to isolate drivers that might need to access those and fix them by providing a proper function to obtain an offset to the legacy IOs of a given bus.

2006-07-03[POWERPC] Add new interrupt mapping core and change platforms to use itBenjamin Herrenschmidt1-17/+0
This adds the new irq remapper core and removes the old one. Because there are some fundamental conflicts with the old code, like the value of NO_IRQ which I'm now setting to 0 (as per discussions with Linus), etc..., this commit also changes the relevant platform and driver code over to use the new remapper (so as not to cause difficulties later in bisecting). This patch removes the old pre-parsing of the open firmware interrupt tree along with all the bogus assumptions it made to try to renumber interrupts according to the platform. This is all to be handled by the new code now. For the pSeries XICS interrupt controller, a single remapper host is created for the whole machine regardless of how many interrupt presentation and source controllers are found, and it's set to match any device node that isn't a 8259. That works fine on pSeries and avoids having to deal with some of the complexities of split source controllers vs. presentation controllers in the pSeries device trees. The powerpc i8259 PIC driver now always requests the legacy interrupt range. It also has the feature of being able to match any device node (including NULL) if passed no device node as an input. That will help porting over platforms with broken device-trees like Pegasos who don't have a proper interrupt tree.
