2013-06-13MIPS: Netlogic: move cpu_ready array to boot areaJayachandran C1-0/+1
Move the nlm_cpu_ready[] array used by the cpu wakeup code to the boot area, along with rest of the boot parameter code. Signed-off-by: Jayachandran C <[email protected]> Cc: [email protected] Patchwork: https://patchwork.linux-mips.org/patch/5425/ Signed-off-by: Ralf Baechle <[email protected]>
2013-06-13MIPS: Netlogic: Initialization when !CONFIG_SMPJayachandran C1-0/+6
The core initialization and reset vector setup needs to be done even when booting uniprocessor.

2013-02-17MIPS: Netlogic: Use PIC timer as a clocksourceJayachandran C1-1/+1
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.

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. Signed-off-by: Ralf Baechle <[email protected]>
2013-01-30MIPS: Netlogic: Fix UP compilation on XLRJayachandran C1-1/+4
The commit 2a37b1a "MIPS: Netlogic: Move from u32 cpumask to cpumask_t" breaks uniprocessor compilation on XLR with: arch/mips/netlogic/xlr/setup.c: In function 'prom_init': arch/mips/netlogic/xlr/setup.c:196:6: error: unused variable 'i' Fix by defining 'i' only when CONFIG_SMP is defined.

2012-11-09MIPS: Netlogic: Support for XLR/XLS Fast Message NetworkGanesan Ramalingam1-0/+9
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.

2012-11-09MIPS: Netlogic: Support for multi-chip configurationJayachandran C1-7/+13
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.

2012-11-09MIPS: Netlogic: Move from u32 cpumask to cpumask_tJayachandran C1-3/+7
Initial code to support more than 32 cpus. The platform CPU mask is updated from 32-bit mask to cpumask_t. Convert places that use cpu_/cpus_ functions to use cpumask_* functions.

2012-07-24MIPS: Netlogic: Remove NETLOGIC_ prefixJayachandran C1-1/+1
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.

2011-12-07MIPS: Netlogic: Merge some of XLR/XLP wakup codeJayachandran C1-1/+6
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.

2011-12-07MIPS: Netlogic: Move code common with XLP to common/Jayachandran C1-8/+16
- 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 Signed-off-by: Jayachandran C <[email protected]> Cc: [email protected] Patchwork: https://patchwork.linux-mips.org/patch/2964/ Signed-off-by: Ralf Baechle <[email protected]>
