|/ | | | | | | | | | | | | | | | | | | This patch moves the generalized implementation of of_get_cpu_node from PowerPC to DT core library, thereby adding support for retrieving cpu node for a given logical cpu index on any architecture. The CPU subsystem can now use this function to assign of_node in the cpu device while registering CPUs. It is recommended to use these helper function only in pre-SMP/early initialisation stages to retrieve CPU device node pointers in logical ordering. Once the cpu devices are registered, it can be retrieved easily from cpu device of_node which avoids unnecessary parsing and matching.

* powerpc/pseries: Update CPU maps when device tree is updatedJesse Larrew2013-04-261-0/+1
| | | | | | | | | | | | | | | | | | | | Platform events such as partition migration or the new PRRN firmware feature can cause the NUMA characteristics of a CPU to change, and these changes will be reflected in the device tree nodes for the affected CPUs. This patch registers a handler for Open Firmware device tree updates and reconfigures the CPU and node maps whenever the associativity changes. Currently, this is accomplished by marking the affected CPUs in the cpu_associativity_changes_mask and allowing arch_update_cpu_topology() to retrieve the new associativity information using hcall_vphn(). Protecting the NUMA cpu maps from concurrent access during an update operation will be addressed in a subsequent patch in this series.

| | | | | | | | | | | | | | | | | 5 bits The firmware_has_feature() function makes it easy to check for supported features of the hypervisor. This patch extends the capability of firmware_has_feature() to include checking for specified bits in vector 5 of the architecture vector as reported in the device tree. As part of this the #defines used for the architecture vector are re-defined such that each option has the index into vector 5 and the feature bit encoded into it. This makes checking for architecture bits when initiating data for firmware_has_feature much easier.

* pci/of: Match PCI devices to OF nodes dynamicallyBenjamin Herrenschmidt2011-06-081-14/+0
| | | | | | | | | | | | | | | | | | | | | | | | powerpc has two different ways of matching PCI devices to their corresponding OF node (if any) for historical reasons. The ppc64 one does a scan looking for matching bus/dev/fn, while the ppc32 one does a scan looking only for matching dev/fn on each level in order to be agnostic to busses being renumbered (which Linux does on some platforms). This removes both and instead moves the matching code to the PCI core itself. It's the most logical place to do it: when a pci_dev is created, we know the parent and thus can do a single level scan for the matching device_node (if any). The benefit is that all archs now get the matching for free. There's one hook the arch might want to provide to match a PHB bus to its device node. A default weak implementation is provided that looks for the parent device device node, but it's not entirely reliable on powerpc for various reasons so powerpc provides its own.

DBG() vs. pr_debug()), the implementations are identical. of_irq_to_resource() is also merged, but in this case the implementations are different.

* of: Rework linux/of.h and asm/prom.h include orderingGrant Likely2009-10-151-6/+1
| | | | | | | | | | | | | | | | | | | | | In preparation to prune things out of the Sparc, PowerPC and Microblaze asm/prom.h files, change the #include statements to ensure that even if asm/prom.h is included first, linux/of.h gets to determine the order in which files are processed. This patch adds a #include <linux/of.h> to each of the prom.h files *above* the multi-include protection macros to ensure that linux/of.h can define things before prom.h gets processed. At the end of the merge the cross dependencies between the files should be gone and a sane #include scheme can be restored. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

* powerpc: Add of_find_next_cache_node()Nathan Lynch2008-12-211-0/+3
| | | | | | | | | | We have more than one piece of code that looks up cache nodes manually using the "l2-cache" property. Add a common helper routine which does this and handles ePAPR's "next-level-cache" property as well as powermac.

* powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell2008-08-041-0/+356
from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
