In times of ARC 700 performance counters didn't have support of interrupt an so for ARC we only had support of non-sampling events. Put simply only "perf stat" was functional. Now with ARC HS we have support of interrupts in performance counters which this change introduces support of. ARC performance counters act in the following way in regard of interrupts generation. [1] A counter counts starting from value set in PCT_COUNT register pair [2] Once counter reaches value set in PCT_INT_CNT interrupt is raised Basic setup look like this: [1] PCT_COUNT = 0; [2] PCT_INT_CNT = __limit_value__; [3] Enable interrupts for that counter and let it run [4] Let counter reach its limit [5] Handle interrupt when it happens Note that PCT HW block is build in CPU core and so ints interrupt line (which is basically OR of all counters IRQs) is wired directly to top-level IRQC. That means do de-assert PCT interrupt it's required to reset IRQs from all counters that have reached their limit values.

This generalization prepares for support of overflow interrupts. Hardware event counters on ARC work that way: Each counter counts from programmed start value (set in ARC_REG_PCT_COUNT) to a limit value (set in ARC_REG_PCT_INT_CNT) and once limit value is reached this timer generates an interrupt. Even though this hardware implementation allows for more flexibility, in Linux kernel we decided to mimic behavior of other architectures this way: [1] Set limit value as half of counter's max value (to allow counter to run after reaching it limit, see below for more explanation): ---------->8----------- arc_pmu->max_period = (1ULL << counter_size) / 2 - 1ULL; ---------->8----------- [2] Set start value as "arc_pmu->max_period - sample_period" and then count up to the limit Our event counters don't stop on reaching max value (the one we set in ARC_REG_PCT_INT_CNT) but continue to count until kernel explicitly stops each of them. And setting a limit as half of counter capacity is done to allow capturing of additional events in between moment when interrupt was triggered until we're actually processing PMU interrupts. That way we're trying to be more precise. For example if we count CPU cycles we keep track of cycles while running through generic IRQ handling code: [1] We set counter period as say 100_000 events of type "crun" [2] Counter reaches that limit and raises its interrupt [3] Once we get in PMU IRQ handler we read current counter value from ARC_REG_PCT_SNAP ans see there something like 105_000. If counters stop on reaching a limit value then we would miss additional 5000 cycles.

When kernel's binary becomes large enough (32M and more) errors may occur during the final linkage stage. It happens because the build system uses short relocations for ARC by default. This problem may be easily resolved by passing -mlong-calls option to GCC to use long absolute jumps (j) instead of short relative branchs (b). But there are fragments of pure assembler code exist which use branchs in inappropriate places and cause a linkage error because of relocations overflow. First of these fragments is .fixup insertion in futex.h and unaligned.c. It inserts a code in the separate section (.fixup) with branch instruction. It leads to the linkage error when kernel becomes large. Second of these fragments is calling scheduler's functions (common kernel code) from entry.S of ARC's code. When kernel's binary becomes large it may lead to the linkage error because scheduler may occur far enough from ARC's code in the final binary.

Callers of cmpxchg_futex_value_locked() in futex code expect bimodal return value: !0 (essentially -EFAULT as failure) 0 (success) Before this patch, the success return value was old value of futex, which could very well be non zero, causing caller to possibly take the failure path erroneously.

In case of ARCv2 CPU there're could be following configurations that affect cache handling for data exchanged with peripherals via DMA: [1] Only L1 cache exists [2] Both L1 and L2 exist, but no IO coherency unit [3] L1, L2 caches and IO coherency unit exist Current implementation takes care of [1] and [2]. Moreover support of [2] is implemented with run-time check for SLC existence which is not super optimal. This patch introduces support of [3] and rework of DMA ops usage. Instead of doing run-time check every time a particular DMA op is executed we'll have 3 different implementations of DMA ops and select appropriate one during init. As for IOC support for it we need: [a] Implement empty DMA ops because IOC takes care of cache coherency with DMAed data [b] Route dma_alloc_coherent() via dma_alloc_noncoherent() This is required to make IOC work in first place and also serves as optimization as LD/ST to coherent buffers can be srviced from caches w/o going all the way to memory Signed-off-by: NAlexey Brodkin <abrodkin@synopsys.com> [vgupta: -Added some comments about IOC gains -Marked dma ops as static, -Massaged changelog a bit] Signed-off-by: NVineet Gupta <vgupta@synopsys.com>

Pull MIPS fixes from Ralf Baechle: "Another round of MIPS fixes for 4.2. No area does particularly stand out but we have a two unpleasant ones: - Kernel ptes are marked with a global bit which allows the kernel to share kernel TLB entries between all processes. For this to work both entries of an adjacent even/odd pte pair need to have the global bit set. There has been a subtle race in setting the other entry's global bit since ~ 2000 but it take particularly pathological workloads that essentially do mostly vmalloc/vfree to trigger this. This pull request fixes the 64-bit case but leaves the case of 32 bit CPUs with 64 bit ptes unsolved for now. The unfixed cases affect hardware that is not available in the field yet. - Instruction emulation requires loading instructions from user space but the current fast but simplistic approach will fail on pages that are PROT_EXEC but !PROT_READ. For this reason we temporarily do not permit this permission and will map pages with PROT_EXEC | PROT_READ.
