* powerpc/pmap: Fix wired memory leak in booke64 page directoriesJustin Hibbits2020-06-091-18/+24
| | | | | | | | | | | | Properly handle reference counts in the 64-bit pmap page directories. Otherwise all page table pages would leak due to over-referencing. This would cause a quick enter to swap on a desktop system (AmigaOne X5000) when quitting and rerunning applications, or just building world. Add an INVARIANTS check to validate no leakage at pmap release time. Notes: svn path=/head/; revision=361988
* Prevent TCP Cubic to abruptly increase cwnd after slow-startRichard Scheffenegger2020-06-091-9/+19
| | | | | | | | | | | | | | | | | | Introducing flags to track the initial Wmax dragging and exit from slow-start in TCP Cubic. This prevents sudden jumps in the caluclated cwnd by cubic, especially when the flow is application limited during slow start (cwnd can not grow as fast as expected). The downside is that cubic may remain slightly longer in the concave region before starting the convex region beyond Wmax again.

* | iflib: netmap: honor netmap_irx_irq return valuesVincenzo Maffione2020-06-091-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the receive interrupt routine, always call netmap_rx_irq(). The latter function will return != NM_IRQ_PASS if netmap is not active on that specific receive queue, so that the driver can go on with iflib_rxeof(). Note that netmap supports partial opening, where only a subset of the RX or TX rings can be open in netmap mode. Checking the IFCAP_NETMAP flag is not enough to make sure that the queue is indeed in netmap mode. Moreover, in case netmap_rx_irq() returns NM_IRQ_RESCHED, it means that netmap expects the driver to call netmap_rx_irq() again as soon as possible. Currently, this may happen when the device is attached to a VALE switch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code was computing an incorrect value in a very expensive manner. "sharedram" is supposed to be the amount of memory used by named swap objects, which on FreeBSD basically corresponds to memory usage by shared memory objects (including, for example, GEM objects) and tmpfs. We currently have no cheap way to count such pages. The previous code tried to determine the number of copy-on-write pages shared between processes. Just replace the computed value with 0. illumos reportedly does the same thing. Linux itself did not populate this field until a 2014 commit, "mm: export NR_SHMEM via sysinfo(2) / si_meminfo() interfaces".

Extend the offload KPI with optional PDU queue method, allowing to specify completion callback, called when all the data referenced by above has been transferred and won't be accessed any more (the buffers can be freed). Implement the above functionality in software iSCSI driver using mbufs with external storage and reference counter. Note that some NICs (ixl(4)) may keep the mbuf in TX queue for a long time, so CTL has to be ready. Add optional method to struct ctl_scsiio for buffer reference counting. Implement it for CTL block backend, allowing to delay free of the struct ctl_be_block_io and memory it references as needed. In first reincarnation of the patch I tried to delay whole I/O as it is done for FibreChannel, that was cleaner, but due to the above callback delays I had to rewrite it this way to not leave LUN referenced potentially for hours or more. All together on sequential read from ZFS ARC this saves about 30% of CPU time and memory bandwidth by avoiding one of 3 memory copies (the other two are from ZFS ARC to DMU cache and then from DMU cache to CTL buffers). On tests with 2x Xeon Silver 4114 this allows to reach full line rate of 100GigE NIC. Tests with Gold CPUs and two 100GigE NICs are stil TBD, but expectations to saturate them are pretty high. ;) Discussed with: Chelsio Sponsored by: iXsystems, Inc.

We don't know when the first request came in or how quickly we responded. Nor from a client perspective do we know how long from when we sent out the first byte before the server responded. This small change adds the ability to track the TTFB's. This will show up in BB logging which then can be pulled for later analysis. Note that currently the tracking is via the ticks variable of all three variables. This provides a very rough estimate (hz=1000 its 1ms). A follow-on set of work will be to change all three of these values into something with a much finer resolution (either microseconds or nanoseconds), though we may want to make the resolution configurable so that on lower powered machines we could still use the much cheaper ticks variable.

The DTB written by OpenSBI/BBL is quite small so this is unlikely to hit important data, but if it does this can result in very confusing and hard-to-debug crashes. Add a KASSERT() and a verbose print to catch this problem with debug kernels. While this will not print any output by default if it fails (that would depend on EARLY_PRINTF), at least the kernel now halts reliably instead of randomly crashing.

* | | RISC-V: handle DTB aligned to less than 2MBAlex Richardson2020-06-081-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default OpenSBI and BBL will pass the DTB at a 2MB-aligned address. However, by default there are no 2MB aligned regions between the SBI and the kernel, so we have to choose a 2MB aligned region after the kernel. OpenSBI defaults to placing the DTB 32MB after the start of the kernel but this is not sufficient for a kernel with a large MFS embedded. We could increase this offset to a larger number (e.g. 64/128/256) but that imposes restrictions on the minimum RAM size. Another solution would be to place the DTB between OpenSBI and the kernel at 1MB alignment, but current locore.S code assumes 2MB alignment. With this change I can now boot on QEMU with an OpenSBI configured to store the DTB at an offset of 1MB.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the POWER firmware detects a bad CPU core, it will "GUARD" it out, marking it disabled. Any attempt to spin up a bad CPU will trigger a panic later on when waiting for threads on said core to wake up. Support limping along on fewer cores instead. Notes: svn path=/head/; revision=361901

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86 boot uses loader(8) and the boot2-direct-to-kernel process is not supported.
