* Add support for timeconting in userland.pirofti2020-07-061-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | This diff exposes parts of clock_gettime(2) and gettimeofday(2) to userland via libc eliberating processes from the need for a context switch everytime they want to count the passage of time. If a timecounter clock can be exposed to userland than it needs to set its tc_user member to a non-zero value. Tested with one or multiple counters per architecture. The timing data is shared through a pointer found in the new ELF auxiliary vector AUX_openbsd_timekeep containing timehands information that is frequently updated by the kernel. Timing differences between the last kernel update and the current time are adjusted in userland by the tc_get_timecount() function inside the MD usertc.c file. This permits a much more responsive environment, quite visible in browsers, office programs and gaming (apparently one is are able to fly in Minecraft now). Tested by robert@, sthen@, naddy@, kmos@, phessler@, and many others! OK from at least kettenis@, cheloha@, naddy@, sthen@

* add a BUS_DMA_64BIT flag to bus_dma on all our archs.dlg2017-05-081-14/+15
| | | | | | | | | this is so drivers can advertise that they can handle 64 dma addresses to the platform. it may choose to handle dmamaps differently based on this flag. tweaks and ok tom@ ok kettenis@
* provide splraise on landiskdlg2016-06-141-11/+12
| | | | | | | splraise is a wrapper around the sh _cpu_intr_raise(), and all the splfoo macros are now defined as calling splraise(IPL_FOO). tested on my landisk box
* Initial support for MSI-X. Only supported on amd64 for now. I have diffs tokettenis2016-05-041-1/+2
| | | | | | | | | | actually use this in em(4) and xhci(4), but I'm not committing those yet because we almost certainly need to save and restore the MSI-X registers during suspend/resume. However, this allows mpi@ to play with multiple-vector support in networking hardware. Requested by mpi@ ok mlarkin@, mikeb@

| | | | | | | to keep definitions our of user space. The MD files now follow a consistant order -- all namespace intrusion is at the tail can be cleaned up independently. locore, bootblocks, and libkvm still see enough visibility to build. Checked on 90% of platforms...

| | | | | | | | | MI float.h which pulls in and defines the values that are needed from there, and repair sys/limits.h so that it defines the values it needs as well (depending on POSIX version, XPG version, etc). guenther has a more exact selection of that coming for limits.h. this also fixes a few mistakes for the vax. reviewed by kettenis and guenther.

* Introduce pci_probe_device_hook(pci_chipset_tag_t, struct pci_attach_args *).miod2011-10-101-1/+2
| | | | | | | | | | | | | | | | | | This mandatory function will get invoked in pci_probe_device(), and allows a pci host driver to alter the pci_attach_args passed to a device when attaching. This function will also, if returning non-zero, cause the device to be skipped completely during all the phases of the PCI device discovery (i.e. ressource enumeration, ressource assignment, and actual attachment). This particular feature is experimental and might be reverted in the future (or the scope narrowed to device attachment only). A dummy #define pci_probe_device_hook() 0 is added to all platforms except sgi, where real functions (currently only returning 0) are added; real meat will be added shortly. Discussed at s2k11, no objection from the usual suspects.
* Nuke the useless D_KQFILTER flag and just check that d_kqfilter isnicm2011-07-041-2/+2

* machdep.kbdreset enables a shutdown by Ctrl-Alt-Del on amd64 andnaddy2011-06-241-4/+4
| | | | | | | | | | | | | | | i386. Stop abusing it on other archs for controling a shutdown by pressing the soft power button: * Add a MI sysctl hw.allowpowerdown; if set to 1 (the default) it allows a power button shutdown. * Make acpi(4)/acpibtn(4) honor hw.allowpowerdown. * Switch the various power button intercepts on landisk, sgi, sparc64 and zaurus over to hw.allowpowerdown. * Garbage collect the machdep.kbdreset sysctl on all archs other than amd64 and i386. ok miod@
* Remove the freelist member from vm_physsegoga2011-05-301-4/+1
| | | | | | | | | | | | | | | | | | The new world order of pmemrange makes this data completely redundant (being dealt with by the pmemrange constraints instead). Remove all code that messes with the freelist. While touching every caller of uvm_page_physload() anyway, add the flags argument to all callers (all but one is 0 and that one already used PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue without it. Should shrink the code a bit, as well. matthew@ pointed out some mistakes i'd made. ``freelist death, I like. Ok.' ariane@ `I agree with the general direction, go ahead and i'll fix any fallout shortly'' miod@ (68k 88k and vax i could not check would build)

* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-264-32/+4
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@
