MIPS: Netlogic: Use PIC timer as a clocksource

2013-02-16T23:15:20+00:00

The XLR/XLS/XLP PIC has a 8 countdown timers which run at the PIC
frequencey. One of these can be used as a clocksource to provide
timestamps that is common across cores. This can be used in place
of the count/compare clocksource which is per-CPU.

On XLR/XLS PIC registers are 32-bit, so we just use the lower 32-bits
of the PIC counter. On XLP, the whole 64-bit can be used.

Provide common macros and functions for PIC timer registers on XLR/XLS
and XLP, and use them to register a PIC clocksource.

MIPS: Whitespace cleanup.

2013-02-01T09:00:22+00:00

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

MIPS: Netlogic: Support for XLR/XLS Fast Message Network

2012-11-09T10:37:20+00:00

On XLR/XLS, the cpu cores communicate with fast on-chip devices
(e.g. network accelerator, security engine etc.) using the Fast
Messaging Network(FMN). The FMN queues and credits needs to be
configured and intialized before it can be used.

The co-processor 2 on XLR/XLS CPU cores has registers for FMN access,
and the XLR/XLS has custom instructions for sending and loading
messages.  The FMN can deliver also per-cpu interrupts when messages
are available at the CPU.

This patch adds FMN initialization, adds interrupt setup and handling,
and also provides support for sending and receiving FMN messages.

MIPS: Netlogic: Support for multi-chip configuration

2012-11-09T10:37:19+00:00

Upto 4 Netlogic XLP SoCs can be connected over ICI links to form a
coherent multi-node system.  Each SoC has its own set of on-chip
devices including PIC.  To support this, add a per SoC stucture and
use it for the PIC and SYS block addresses instead of using global
variables.

MIPS: Netlogic: Remove NETLOGIC_ prefix

2012-07-24T15:28:53+00:00

Remove NETLOGIC_ prefix from gpio register definitions, this will
bring it in-line with the other Netlogic headers.

Having NETLOGIC prefix here is misleading because these are XLR/XLS
specific register definitions.

MIPS: Netlogic: Merge some of XLR/XLP wakup code

2011-12-07T22:04:56+00:00

Create a common NMI and reset handler in smpboot.S and use this for
both XLR and XLP.  In the earlier code, the woken up CPUs would
busy wait until released, switch this to wakeup by NMI.

The initial wakeup code or XLR and XLP are differ since they are
started from different bootloaders (XLP from u-boot and XLR from
netlogic bootloader). But in both platforms the woken up CPUs wait
and are released by sending an NMI.

Add support for starting XLR and XLP in 1/2/4 threads per core.

MIPS: Netlogic: Move code common with XLP to common/

2011-12-07T22:04:55+00:00

- Move code that can be shared with XLP (irq.c, smp.c, time.c and
  xlr_console.c) to arch/mips/netlogic/common
- Add asm/netlogic/haldefs.h and asm/netlogic/common.h for common and
  io functions shared with XLP
- remove type 'nlm_reg_t *' and use uint64_t for mmio offsets
- Move XLR specific code in smp.c to xlr/wakeup.c
- Move XLR specific PCI code from irq.c to mips/pci/pci-xlr.c
- Provide API for pic functions called from common/irq.c
