| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The workaround for AMD erratum 400 uses the term "c1e" falsely suggesting: 1. Intel C1E is somehow involved 2. All AMD processors with C1E are involved Use the string "amd_c1e" instead of simply "c1e" to clarify that this workaround is specific to AMD's version of C1E. Use the string "e400" to clarify that the workaround is specific to AMD processors with Erratum 400.

It did it by remapping apicid to PXM mapping, even when amdtopology is being used. There is no reason to go through such convolution. The generic code has all the information necessary to transform the distance table to the emulated nid space. Implement generic distance table transformation in numa_emulation() and drop private implementations in srat_64 and amdtopology_64. This makes find_node_by_addr() and fake_physnodes() and related functions unnecessary, drop them.

This patch implements generic node distance handling. NUMA init methods can call numa_set_distance() to set distance between nodes and the common __node_distance() implementation will report the set distance. Due to the way NUMA emulation is implemented, the generic node distance handling is used only when emulation is not used. Later patches will update NUMA emulation to use the generic distance mechanism.

* x86, numa: Fix cpu to node mapping for sparse node idsDavid Rientjes2010-12-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NUMA boot code assumes that physical node ids start at 0, but the DIMMs that the apic id represents may not be reachable. If this is the case, node 0 is never online and cpus never end up getting appropriately assigned to a node. This causes the cpumask of all online nodes to be empty and machines crash with kernel code assuming online nodes have valid cpus. The fix is to appropriately map all the address ranges for physical nodes and ensure the cpu to node mapping function checks all possible nodes (up to MAX_NUMNODES) instead of simply checking nodes 0-N, where N is the number of physical nodes, for valid address ranges. This requires no longer "compressing" the address ranges of nodes in the physical node map from 0-N, but rather leave indices in physnodes[] to represent the actual node id of the physical node. Accordingly, the topology exported by both amd_get_nodes() and acpi_get_nodes() no longer must return the number of nodes to iterate through; all such iterations will now be to MAX_NUMNODES. This change also passes the end address of system RAM (which may be different from normal operation if mem= is specified on the command line) before the physnodes[] array is populated. ACPI parsed nodes are truncated to fit within the address range that respect the mem= boundaries and even some physical nodes may become unreachable in such cases. When NUMA emulation does succeed, any apicid to node mapping that exists for unreachable nodes are given default values so that proximity domains can still be assigned. This is important for node_distance() to function as desired.

* x86, numa: Fake apicid and pxm mappings for NUMA emulationDavid Rientjes2010-12-231-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds the equivalent of acpi_fake_nodes() for AMD Northbridge platforms. The goal is to fake the apicid-to-node mappings for NUMA emulation so the physical topology of the machine is correctly maintained within the kernel. This change also fakes proximity domains for both ACPI and k8 code so the physical distance between emulated nodes is maintained via node_distance(). This exports the correct distances via /sys/devices/system/node/.../distance based on the underlying topology. A new helper function, fake_physnodes(), is introduced to correctly invoke the correct NUMA code to fake these two mappings based on the system type. If there is no underlying NUMA configuration, all cpus are mapped to node 0 for local distance. Since acpi_fake_nodes() is no longer called with CONFIG_ACPI_NUMA, it's prototype can be removed from the header file for such a configuration.

* ACPI: delete the "acpi=ht" boot optionLen Brown2010-03-141-2/+0
| | | | | | | | | | | | | | | | | | | acpi=ht was important in 2003 -- before ACPI was universally deployed and enabled by default in the major Linux distributions. At that time, there were a fair number of people who or chose to, or needed to, run with acpi=off, yet also wanted access to Hyper-threading. Today we find that many invocations of "acpi=ht" are accidental, and thus is it possible that it is doing more harm than good. In 2.6.34, we warn on invocation of acpi=ht. In 2.6.35, we delete the boot option. Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | This is the counterpart to "x86: export k8 physical topology" for SRAT. It is not as invasive because the acpi code already seperates node setup into detection and registration steps, with the exception of registering e820 active regions in acpi_numa_memory_affinity_init(). This is now moved to acpi_scan_nodes() if NUMA emulation is disabled or deferred. acpi_numa_init() now returns a value which specifies whether an underlying SRAT was located. If so, that topology can be used by the emulation code to interleave emulated nodes over physical nodes or to register the nodes for ACPI. acpi_get_nodes() may now be used to export the srat physical topology of the machine for NUMA emulation.

Implement this by just removing the previous mapping each time its called. Unfortunately, this will leave a stray mapping at the end.

* ACPI: pci_link: remove acpi_irq_balance_set() interfaceBjorn Helgaas2008-11-111-1/+0
| | | | | | | | | | | | | | | | | | | This removes the acpi_irq_balance_set() interface from the PCI interrupt link driver. x86 used acpi_irq_balance_set() to tell the PCI interrupt link driver to configure links to minimize IRQ sharing. But the link driver can easily figure out whether to turn on IRQ balancing based on the IRQ model (PIC/IOAPIC/etc), so we can get rid of that external interface. It's better for the driver to figure this out at init-time. If we set it externally via the x86 code, the interface reduces modularity, and we depend on the fact that acpi_process_madt() happens before we process the kernel command line.
