2017-01-03MIPS: Netlogic: Fix assembler warning from smpboot.SPaul Burton1-2/+2
The netlogic platform can be built for either MIPS32 or MIPS64, and when built for MIPS32 (as by nlm_xlr_defconfig) the use of the dla pseudo-instruction leads to warnings such as the following from recent versions of the GNU assembler: arch/mips/netlogic/common/smpboot.S: Assembler messages: arch/mips/netlogic/common/smpboot.S:62: Warning: dla used to load 32-bit register; recommend using la instead arch/mips/netlogic/common/smpboot.S:63: Warning: dla used to load 32-bit register; recommend using la instead Avoid these warnings by using the PTR_LA macro to make use of the appropriate la or dla pseudo-instruction for the build.

2017-01-03MIPS: Netlogic: Exclude netlogic,xlp-pic code from XLR buildsPaul Burton1-2/+2
Code in arch/mips/netlogic/common/irq.c which handles the XLP PIC fails to build in XLR configurations due to cpu_is_xlp9xx not being defined, leading to the following build failure: arch/mips/netlogic/common/irq.c: In function ‘xlp_of_pic_init’: arch/mips/netlogic/common/irq.c:298:2: error: implicit declaration of function ‘cpu_is_xlp9xx’ [-Werror=implicit-function-declaration] if (cpu_is_xlp9xx()) { ^ Although the code was conditional upon CONFIG_OF which is indirectly selected by CONFIG_NLM_XLP_BOARD but not CONFIG_NLM_XLR_BOARD, the failing XLR with CONFIG_OF configuration can be configured manually or by randconfig.

2016-08-04dma-mapping: use unsigned long for dma_attrsKrzysztof Kozlowski1-2/+2
The dma-mapping core and the implementations do not change the DMA attributes passed by pointer. Thus the pointer can point to const data. However the attributes do not have to be a bitfield. Instead unsigned long will do fine: 1. This is just simpler. Both in terms of reading the code and setting attributes. Instead of initializing local attributes on the stack and passing pointer to it to dma_set_attr(), just set the bits. 2. It brings safeness and checking for const correctness because the attributes are passed by value.

A couple of netlogic assembly files define CP0_EBASE to $15, the same as CP0_PRID in mipsregs.h, and use it for accessing both CP0_PRId and CP0_EBase registers. However commit 609cf6f2291a ("MIPS: CPS: Early debug using an ns16550-compatible UART") added a different definition of CP0_EBASE to mipsregs.h, which included a register select of 1. This causes harmless build warnings like the following: arch/mips/netlogic/common/reset.S:53:0: warning: "CP0_EBASE" redefined #define CP0_EBASE $15 ^ In file included from arch/mips/netlogic/common/reset.S:41:0: ./arch/mips/include/asm/mipsregs.h:63:0: note: this is the location of the previous definition #define CP0_EBASE $15, 1 ^ Update the code to use the definitions from mipsregs.h for accessing both registers.

2015-09-10dma-mapping: consolidate dma_{alloc,free}_{attrs,coherent}Christoph Hellwig1-10/+0
Since 2009 we have a nice asm-generic header implementing lots of DMA API functions for architectures using struct dma_map_ops, but unfortunately it's still missing a lot of APIs that all architectures still have to duplicate. This series consolidates the remaining functions, although we still need arch opt outs for two of them as a few architectures have very non-standard implementations. This patch (of 5): The coherent DMA allocator works the same over all architectures supporting dma_map operations. This patch consolidates them and converges the minor differences: - the debug_dma helpers are now called from all architectures, including those that were previously missing them - dma_alloc_from_coherent and dma_release_from_coherent are now always called from the generic alloc/free routines instead of the ops dma-mapping-common.h always includes dma-coherent.h to get the defintions for them, or the stubs if the architecture doesn't support this feature - checks for ->alloc / ->free presence are removed. There is only one magic instead of dma_map_ops without them (mic_dma_ops) and that one is x86 only anyway. Besides that only x86 needs special treatment to replace a default devices if none is passed and tweak the gfp_flags. An optional arch hook is provided for that.

2015-08-03MIPS: SMP: Don't increment irq_count multiple times for call function IPIsAlex Smith1-1/+1
The majority of SMP platforms handle their IPIs through do_IRQ() which calls irq_{enter/exit}(). When a call function IPI is received, smp_call_function_interrupt() is called which also calls irq_{enter,exit}(), meaning irq_count is raised twice. When tick broadcasting is used (which is implemented via a call function IPI), this incorrectly causes all CPU idle time on the core receiving broadcast ticks to be accounted as time spent servicing IRQs, as account_process_tick() will account as such if irq_count is greater than 1. This results in 100% CPU usage being reported on a core which receives its ticks via broadcast. This patch removes the SMP smp_call_function_interrupt() wrapper which calls irq_{enter,exit}(). Platforms which handle their IPIs through do_IRQ() now call generic_smp_call_function_interrupt() directly to avoid incrementing irq_count a second time. Platforms which don't (loongson, sgi-ip27, sibyte) call generic_smp_call_function_interrupt() wrapped in irq_{enter,exit}().

Pull MIPS updates from Ralf Baechle: - three fixes for 3.15 that didn't make it in time - limited Octeon 3 support. - paravirtualization support - improvment to platform support for Netlogix SOCs. - add support for powering down the Malta eval board in software - add many instructions to the in-kernel microassembler. - add support for the BPF JIT. - minor cleanups of the BCM47xx code. - large cleanup of math emu code resulting in significant code size reduction, better readability of the code and more accurate emulation. - improvments to the MIPS CPS code. - support C3 power status for the R4k count/compare clock device. - improvments to the GIO support for older SGI workstations. - increase number of supported CPUs to 256; this can be reached on certain embedded multithreaded ccNUMA configurations. - various small cleanups, updates and fixes * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (173 commits) MIPS: IP22/IP28: Improve GIO support MIPS: Octeon: Add twsi interrupt initialization for OCTEON 3XXX, 5XXX, 63XX DEC: Document the R4k MB ASIC mini interrupt controller DEC: Add self as the maintainer MIPS: Add microMIPS MSA support.
