* pmc(3)/hwpmc(4): update supported Intel processors to rely fully on theMatt Macy2018-05-26255-2108/+572
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vendor provided pmu-events tables and sundry cleanups. The vendor pmu-events tables provide counter descriptions, default sample rates, event, umask, and flag values for all the counter configuration permutations. Using this gives us: - much simpler kernel code for the MD component - helpful long and short event descriptions - simpler user code - sample rates that won't overload the system Update man page with newer sample types and remove unused sample type.

* On POWER9 clear the HID0_RADIX before enabling the page tablesJustin Hibbits2018-05-262-0/+8
| | | | | | | | | | | | | POWER9 supports Radix page tables in addition to Hashed page tables. When Radix page tables are in use, the TLB is cut in half, so that half of the TLB is used for the page walk cache. This is the default behavior, however FreeBSD currently does not support Radix tables. Clear this bit so that we can use the full TLB. Do this in the MMU logic so that configuration can be localized to the specific translation format. Once we do support Radix tables, the setup for that will be localized to the Radix MMU kobj.

Essentially, one pmap_enter(..., psind=1) call takes the place of 512 pmap_enter(..., psind=0) calls, and that one pmap_enter(..., psind=1) call eliminates the allocation of a page table page.

| | | | | | | | | | | | | | | | | | | | ixl(4)'s nvmupdate utility expects the nvmupdate process to run while the interface is down; these nvm update commands use the admin queue, so the admin queue needs to be able to generate interrupts and be processed while the interface is down. So add a flag that ixl(4) sets that lets the entire admin task run even when the interface is marked down/IFF_DRV_RUNNING isn't set. With this change, nvmupdate should function like it did pre-iflib.

* Optimize i386 pmap_extract_and_hold().Konstantin Belousov2018-05-252-5/+19
| | | | | | | | | | | | | | | | | | | | | In particular, stop using pmap_pte() to read non-promoted pte while walking the page table. pmap_pte() needs to shoot down the kernel mapping globally which causes IPI broadcast. Since pmap_extract_and_hold() is used for slow copyin(9), it is very significant hit for the 4/4 kernels. Instead, create single purpose per-processor page frame and use it to locally map page table page inside the critical section, to avoid reuse of the frame by other thread if context switched. Measurement demostrated very significant improvements in any load that utilizes copyin/copyout.

| | | | | | | | | | | | | | | | | | | | | | It turns out that sendfile_swapin() has an optimization where it may insert pointers to bogus_page into the page array that it passes to VOP_GETPAGES. That happens to work with buffer cache, because it extensively uses bogus_page internally, so it has the necessary checks. However, ZFS did not expect bogus_page as VOP_GETPAGES(9) does not document such a (ab)use of bogus_page. So, this commit adds checks and handling of bogus_page. I expect that use of bogus_page with VOP_GETPAGES will get documented sooner rather than later.

* Refactor NVMe CAM integration.Alexander Motin2018-05-259-145/+271
| | | | | | | | | | | | | | | | | | | | | | | | - Remove layering violation, when NVMe SIM code accessed CAM internal device structures to set pointers on controller and namespace data. Instead make NVMe XPT probe fetch the data directly from hardware. - Cleanup NVMe SIM code, fixing support for multiple namespaces per controller (reporting them as LUNs) and adding controller detach support and run-time namespace change notifications. - Add initial support for namespace change async events. So far only in CAM mode, but it allows run-time namespace arrival and departure. - Add missing nvme_notify_fail_consumers() call on controller detach. Together with previous changes this allows NVMe device detach/unplug. Non-CAM mode still requires a lot of love to stay on par, but at least CAM mode code should not stay in the way so much, becoming much more self-sufficient.
