MIPS: Netlogic: Move cores per node out of multi-node.h

2015-04-01T15:21:50+00:00

Use the current_cpu_data package field to get the node of the current CPU.

This allows us to remove xlp_cores_per_node and move nlm_threads_per_node()
and nlm_cores_per_node() to netlogic/common.h, which simplifies code.

MIPS: Netlogic: Use MIPS topology.h

2015-04-01T15:21:50+00:00

commit bda4584cd943 ("MIPS: Support CPU topology files in sysfs")
added topology related macros for all MIPS platforms and commit
bbbf6d8768f5 ("MIPS: NL: Fix nlm_xlp_defconfig build error")
removed most of the contents from mach-netlogic/topology.h.

The netlogic specific topology is not needed anymore, we just need
to setup the package field in current_cpu_data.

MIPS: Create a common

2015-03-31T09:59:40+00:00

11 platforms require at least one of these workarounds to be enabled; 22
platforms do not.  In the latter case we can fall back to a generic version.

Note that this also deletes an orphaned reference to RM9000_CDEX_SMP_WAR.

MIPS: NL: Fix nlm_xlp_defconfig build error

2014-08-19T15:48:44+00:00

The nlm_xlp_defconfig build fails with

./arch/mips/include/asm/mach-netlogic/topology.h:15:0:
			error: "topology_core_id" redefined [-Werror]
In file included from include/linux/smp.h:59:0,
	[ ...]
                 from arch/mips/mm/dma-default.c:12:
./arch/mips/include/asm/smp.h:41:0:
			note: this is the location of the previous definition

and similar errors.

This is caused by commit bda4584cd943d7 ("MIPS: Support CPU topology files
in sysfs") which adds the defines to arch/mips/include/asm/smp.h.

Remove the defines from arch/mips/include/asm/mach-netlogic/topology.h
as no longer necessary.

MIPS: Netlogic: Fix uniprocessor compilation

2014-05-30T14:44:55+00:00

The macros in topology.h need CONFIG_SMP, and the uniprocessor compilation
fails due to this. Wrap the macros in an ifdef so that uniprocessor works.

MIPS: Netlogic: Add cpu to node mapping for XLP9XX

2014-01-24T21:39:49+00:00

XLP9XX has 20 cores per node, opposed to 8 on earlier XLP8XX.
Update code that calculates node id from cpu id to handle this.

MIPS: Netlogic: update iomap.h for XLP9XX

2014-01-24T21:39:48+00:00

Most IO block offsets have changed in XLP9XX. Update iomap.h to add the
new addresses of different SoC blocks like PIC, SYS, UART etc. that are
needed by the base code.

On XLP9xx, the SoC blocks of other nodes are seen on a PCI bus
corresponding to the node. Update iomap code to reflect this.

MIPS: Netlogic: Add macro for node present

2014-01-24T21:39:47+00:00

Add macro nlm_node_present() that can be used to check if a node is present
in a multi-chip configuration. This can be used even when NUMA is not enabled.

MIPS: Netlogic: Add MSI support for XLP

2014-01-24T21:39:46+00:00

Add MSI chip and MSIX chip definitions.

For MSI, we map the link interrupt to a MSI link IRQ which will
do a second level of dispatch based on the MSI status register.

The MSI chip definitions use the MSI enable register to enable
and disable the MSI irqs.

For MSI-X, we split the 32 available MSI-X vectors across the
four PCIe links (8 each). These PIC interrupts generate an IRQ
per link which uses a second level dispatch as well.

The MSI-X chip definition uses the standard functions to enable
and disable interrupts.
