2012-10-10Add __BEGIN_DECLS so that programs using C++ can use functionsStuart Henderson
defined in sysarch.h again, they were broken following the change to NO_IMPLICIT_EXTERN_C. help/ok kettenis@
2012-10-08Revamp the sequences for suspend/hibernate -> resume so that the codeTheo de Raadt
paths are reflexive. It is now possible to fail part-way through a suspend sequence, and recover along the resume code path. Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used after hibernate (and suspend too) to finish the job. Some drivers must be converted at the same time to use this instead of shutdown hooks (the others will follow at a later time) ok kettenis mlarkin

2012-08-07Move the common bits of syscall invocation and return handling intoPhilip Guenthe
an MI file, <sys/syscall_mi.h>, correcting inconsistencies and the handling when copyin() of arguments fails. Tested on i386, amd64, sparc64, and alpha (thanks naddy@) Any issues with other platforms will be fixed in tree. header name from millert@; ok miod@

2012-06-26create new machine/_float.h which is namespace clean. create a newTheo de Raadt
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.

count processes instead of threads. New sysctl()s KERN_NTHREADS and KERN_MAXTHREAD count and limit threads. The nprocs and maxproc kernel variables are replaced by nprocess, maxprocess, nthreads, and maxthread. ok tedu@ mikeb@

2011-10-27Specify the TLS variant for each platform.Philip Guenthe
2011-10-22Comment out wsmux to save kernel text, since USB support is missing fromMiod Vallat
this kernel anyway.
2011-10-10Introduce pci_probe_device_hook(pci_chipset_tag_t, struct pci_attach_args *).Miod Vallat
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.

compat names kept in <machine/param.h>. In <sys/socket.h>, pull in <sys/_types.h> instead of the namespace polluting <machine/param.h> and completely eliminate __CMSG_ALIGN, replaced by _ALIGN ok deraadt@
2011-09-08Make the INT_FAST*_{MIN,MAX} macros match the types they're defined to.Philip Guenthe
Since the underlying types of the int_fast types are set by machine/_types.h, put internal macros in that same file and define the exposed INT_FAST*_{MIN,MAX} macros from those. ok millert@, kettenis@
2011-09-04Driver for the TURBOchannel alpha baseboard audio. Ported from NetBSD, withMiod Vallat
changes to allow using non-native encodings, and alpha specific code to try and avoid doing 8 bit memory access. Tested on 3000/300LX, deaf testing on 3000/600.

2011-07-06Make alpha consistent with our other architectures by using "longMatthew Dempsky
long" for __off_t. This is a C++ ABI bump, but martynas@ already bumped libstdc++. Discussed and requested by many on icb.
2011-07-05Recommit the reverted sigacts change now that the NFS use-after-freePhilip Guenthe
problem has been tracked down. This fixes the sharing of the signal handling state: shared bits go in sigacts, per-rthread bits goes in struct proc. ok deraadt@
2011-06-29Replace all instances of "scsibus* at hba?" with a single "scsibus* atMatthew Dempsky
scsi?" rule, similar to how ethernet PHY drivers attach at mii. Discussed on icb.
2011-06-26if_downall() cannot be done MI in sys_reboot() because vfs_shutdown()Theo de Raadt
might need network (ie. nfs). Move the call to the MD boot() routines. This cause for boot hangs diagnosed by kettenis.
2011-06-23Fix the error path in bus_dmamem_map.Ariane van der Steldt
As discussed on icb: remove the comment, remove pmap_remove (uvm_km_free does that for us). ok oga@, deraadt@
2011-06-17M_WAITOK cleanup of two cases:Michael Knudsen
1) Allocating with M_WAITOK, checking for NULL, and calling panic() is pointless (malloc() will panic if it can't allocate) so remove the check and the call. 2) Allocating with M_WAITOK, checking for NULL, and then gracefully handling failure to allocate is pointless. Instead also pass M_CANFAIL so malloc() doesn't panic so we can actually handle it gracefully. 1) was done using Coccinelle. Input from oga. ok miod.
2011-06-06Forgot to `cvs add' this file during alpha boot block changes, sorry.Miod Vallat
2011-06-05Update alpha bootblocks to use MI loadfile code instead of rolling our own;Miod Vallat
also print a meaningful message if the kernel load address conflicts with the SRM memory areas, so that we can know which kernel load address to use. Requires `make includes' before attempting to build bootblocks. Tweaks mk@, `nice' deraadt@
2011-06-05Move the bufcachepercent setting code to MI locations -- set it to 42%Theo de Raadt
for now; that is unlikely to hit some of the remaining starvation bugs. Repair the bufpages calculation too; i386 was doing it ahead of time (incorrectly) and then re-calculating it. ok thib
2011-05-30Remove the freelist member from vm_physsegOwain Ainsworth
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)
