* flua: initial support for "require" in the base systemEd Maste2020-08-132-3/+7
| | | | | | | | | | | | | | | | | | | | Use /usr not /usr/local for base system components. Use /usr/lib/flua and /usr/share/flua (not lua) for consistency and to avoid the possibility that other software accidentally finds our base system modules. Also drop the version from the path, as flua represents an unspecified lua version that corresponds to the FreeBSD version it comes with. LUA_USE_DLOPEN is not yet enabled because some additional changes are needed wrt symbol visibility.

It is fine to reuse the same file here but we need to be explicit and use open() instead of mkstemp() on the second use. While touching this file also avoid a hardcoded /bin/pwd since that may not work when building on non-FreeBSD systems.

| | | | | | | | | | | | | | For drivers with IFLIB_HAS_RXCQ set, there is a separate completion queue. In this case, the netmap rxsync routine needs to update rxq->ifr_cq_cidx in the same way it is updated by iflib_rxeof().

* aw_cir: lower activation threshold to support NECx protocolAndriy Gapon2020-08-121-5/+7
| | | | | | | | | | | | | | | | | | | | | | | In NECx the leading mark has length of 8T as opposed to 16T in NEC, where T is 562.5 us. So, 4.5 ms. Our threshold was set to 128 * 42.7 us (derived from the sampling frequency of 3/128 MHz). So, ~5.5 ms. The new threshold is set to AW_IR_L1_MIN. I think that's a good enough lower bound for detecting the leading pulse. Also, calculations of active_delay (which is activation delay) are fixed. Previously they would be wrong if AW_IR_ACTIVE_T was anything but zero, because the value was already bit-shifted. Finally, I am not sure why the activation delay was divided by two when calculating the initial pulse length. I have not found anything that would explain or justify it. So, I removed that division.

* Add support for multithreading the inactive queue pageout within a domain.Conrad Meyer2020-08-115-27/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In very high throughput workloads, the inactive scan can become overwhelmed as you have many cores producing pages and a single core freeing. Since Mark's introduction of batched pagequeue operations, we can now run multiple inactive threads working on independent batches. To avoid confusing the pid and other control algorithms, I (Jeff) do this in a mpi-like fan out and collect model that is driven from the primary page daemon. It decides whether the shortfall can be overcome with a single thread and if not dispatches multiple threads and waits for their results. The heuristic is based on timing the pageout activity and averaging a pages-per-second variable which is exponentially decayed. This is visible in sysctl and may be interesting for other purposes. I (Jeff) have verified that this does indeed double our paging throughput when used with two threads. With four we tend to run into other contention problems. For now I would like to commit this infrastructure with only a single thread enabled. The number of worker threads per domain can be controlled with the 'vm.pageout_threads_per_domain' tunable.

| | | | | | | | | | | | | | | | | | | Some of the scripts used for libdtrace invoke nawk instead of awk (for example cddl/contrib/opensolaris/lib/libdtrace/common/mknames.sh). When bootstrapping all tools, we get the nawk -> awk link while building usr.bin/awk, but when linking/copying the dependencies from the host we were only adding awk but not nawk. This was silently generating invalid files when building libdtrace with BUILD_WITH_STRICT_TMPPATH=1 since those scripts invoke nawk instead of awk. In addition to adding the missing link this commit also adds set -e to those scripts to catch errors like this in the future.
