* Reduce MAXPHYS back to 128KB on 32bit architectures.Konstantin Belousov2020-11-291-2/+6
| | | | | | | | | | | | | | | Some of them have limited KVA, like arm, which prevents startup from allocating needed number of large pbufs. Other, for instance i386, are dis-balanced enough after 4/4 that blind bump is probably harmful because it allows for much more in-flight io than other tunables are ready for.

* Store MPIDR register in pcpu.Michal Meloun2020-11-293-1/+6
| | | | | | | | | | | | | MPIDR represents physical locality of given core and it should be used as the only viable/robust connection between cpuid (which have zero relation to cores topology) and external description (for example in FDT). It can be used for determining which interrupt is associated to given per-CPU PMU or by scheduler for determining big/little core or cluster topology.

* Only set the PCI bus end when we are reducing itAndrew Turner2020-11-291-4/+5
| | | | | | | | | | | | | | | | | | | | | We read the bus end value from the _CRS method. On some systems we need to further limit it based on the MCFG table. Support this by setting a default value, then update it if needed in the _CRS table, and finally reduce it if it is past the end of the MCFG tabel. This will allow for both systems that use either method to encode this value. This partially reverts r347929, removing the error printf.

* Increase nvme(4) maximum transfer size from 1MB to 2MB.Alexander Motin2020-11-294-19/+16
| | | | | | | | | | | | | | | | | | | | With 4KB page size the 2MB is the maximum we can address with one page PRP. Going further would require chaining, that would add some more complexity. On the other side, to reduce memory consumption, allocate the PRP memory respecting maximum transfer size reported in the controller identify data. Many of NVMe devices support much smaller values, starting from 128KB. To do that we have to change the initialization sequence to pull the data earlier, before setting up the I/O queue pairs. The admin queue pair is still allocated for full MIN(maxphys, 2MB) size, but it is not a big deal, since there is only one such queue with only 16 trackers.

* Make MAXPHYS tunable. Bump MAXPHYS to 1M.Konstantin Belousov2020-11-2899-328/+405
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work.

* kern: cpuset: drop the lock to allocate domainsetsKyle Evans2020-11-281-8/+13
| | | | | | | | | | | | | | | | | | | | | Restructure the loop a little bit to make it a little more clear how it really operates: we never allocate any domains at the beginning of the first iteration, and it will run until we've satisfied the amount we need or we encounter an error. The lock is now taken outside of the loop to make stuff inside the loop easier to evaluate w.r.t. locking. This fixes it to not try and allocate any domains for the freelist under the spinlock, which would have happened before if we needed any new domains.
