* Add two new kernel options to control memory locality on NUMA hardware.Jeff Roberson2019-08-061-4/+5
| | | | | | | | | | | | | | | | - UMA_XDOMAIN enables an additional per-cpu bucket for freed memory that was freed on a different domain from where it was allocated. This is only used for UMA_ZONE_NUMA (first-touch) zones. - UMA_FIRSTTOUCH sets the default UMA policy to be first-touch for all zones. This tries to maintain locality for kernel memory.

* Provide separate accounting for user-wired pages.Mark Johnston2019-05-131-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically we have not distinguished between kernel wirings and user wirings for accounting purposes. User wirings (via mlock(2)) were subject to a global limit on the number of wired pages, so if large swaths of physical memory were wired by the kernel, as happens with the ZFS ARC among other things, the limit could be exceeded, causing user wirings to fail. The change adds a new counter, v_user_wire_count, which counts the number of virtual pages wired by user processes via mlock(2) and mlockall(2). Only user-wired pages are subject to the system-wide limit which helps provide some safety against deadlocks. In particular, while sources of kernel wirings typically support some backpressure mechanism, there is no way to reclaim user-wired pages shorting of killing the wiring process. The limit is exported as vm.max_user_wired, renamed from vm.max_wired, and changed from u_int to u_long. The choice to count virtual user-wired pages rather than physical pages was done for simplicity. There are mechanisms that can cause user-wired mappings to be destroyed while maintaining a wiring of the backing physical page; these make it difficult to accurately track user wirings at the physical page layer. The change also closes some holes which allowed user wirings to succeed even when they would cause the system limit to be exceeded. For instance, mmap() may now fail with ENOMEM in a process that has called mlockall(MCL_FUTURE) if the new mapping would cause the user wiring limit to be exceeded. Note that bhyve -S is subject to the user wiring limit, which defaults to 1/3 of physical RAM. Users that wish to exceed the limit must tune vm.max_user_wired.

* Dynamically allocate IRQ ranges on x86.John Baldwin2018-08-281-3/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, x86 used static ranges of IRQ values for different types of I/O interrupts. Interrupt pins on I/O APICs and 8259A PICs used IRQ values from 0 to 254. MSI interrupts used a compile-time-defined range starting at 256, and Xen event channels used a compile-time-defined range after MSI. Some recent systems have more than 255 I/O APIC interrupt pins which resulted in those IRQ values overflowing into the MSI range triggering an assertion failure. Replace statically assigned ranges with dynamic ranges. Do a single pass computing the sizes of the IRQ ranges (PICs, MSI, Xen) to determine the total number of IRQs required. Allocate the interrupt source and interrupt count arrays dynamically once this pass has completed. To minimize runtime complexity these arrays are only sized once during bootup. The PIC range is determined by the PICs present in the system. The MSI and Xen ranges continue to use a fixed size, though this does make it possible to turn the MSI range size into a tunable in the future. As a result, various places are updated to use dynamic limits instead of constants. In addition, the vmstat(8) utility has been taught to understand that some kernels may treat 'intrcnt' and 'intrnames' as pointers rather than arrays when extracting interrupt stats from a crashdump. This is determined by the presence (vs absence) of a global 'nintrcnt' symbol. This change reverts r189404 which worked around a buggy BIOS which enumerated an I/O APIC twice (using the same memory mapped address for both entries but using an IRQ base of 256 for one entry and a valid IRQ base for the second entry). Making the "base" of MSI IRQ values dynamic avoids the panic that r189404 worked around, and there may now be valid I/O APICs with an IRQ base above 256 which this workaround would incorrectly skip. If in the future the issue reported in PR 130483 reoccurs, we will have to add a pass over the I/O APIC entries in the MADT to detect duplicates using the memory mapped address and use some strategy to choose the "correct" one. While here, reserve room in intrcnts for the Hyper-V counters.

| | | | | | | | | | | | | If the interrupt count is very high (greater than ~42M), notably on one-shot execution on long running systems, the intermediate multiplication step in the rate calculation will overflow the width of a 32-bit architecture long (32 bits), causing the rest of the calculation to calculate with a truncated value, and report very low rates (sometimes 0).

* Update various statements in vmstat(8) to match reality.John Baldwin2018-01-181-20/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - The process stats are actually thread counts rather than process counts. - Simplify various descriptions to remove mention of stats that are updated every 5 seconds (all VM related stats are now "instant", only the load average is updated every 5 seconds). - Don't make any mention of special treatment for processes that have been active in the last 20 seconds. We don't track that stat. - Rework the description of active virtual memory. Call it mapped virtual memory and explicitly point out it is not the same as the active page queue (which corresponds to "Active" in top(1)), and also hint at the possible bogusness of the value (e.g. if a process maps a single page out of a multiple GB file, the entire file's size is considered mapped). - Simplify a few descriptions that implied their output was a value per interval. All of the "rate" values are per-second rates scaled across the interval. - Update a few comments for 'struct vmtotal' along similar lines.

To do per-cpu stats, convert all fields that previously were maintained in the vmmeters that sit in pcpus to counter(9). - Since some vmmeter stats may be touched at very early stages of boot, before we have set up UMA and we can do counter_u64_alloc(), provide an early counter mechanism: o Leave one spare uint64_t in struct pcpu, named pc_early_dummy_counter. o Point counter(9) fields of vmmeter to pcpu[0].pc_early_dummy_counter, so that at early stages of boot, before counters are allocated we already point to a counter that can be safely written to. o For sparc64 that required a whole dummy pcpu[MAXCPU] array. Further related changes: - Don't include vmmeter.h into pcpu.h. - vm.stats.vm.v_swappgsout and vm.stats.vm.v_swappgsin changed to 64-bit, to match kernel representation. - struct vmmeter hidden under _KERNEL, and only vmstat(1) is an exclusion.
