* create new machine/_float.h which is namespace clean. create a newderaadt2012-06-262-58/+35
| | | | | | | | | 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.

| | | | | C code. Will be used on beagle to process machine id and atags. Looked at by uwe@, tested on beagle/armish/zaurus.
* 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.

* Late spring cleaning of the arm code for old dusty bits we do not want tomiod2011-09-2013-257/+43
| | | | | | | | | | | | | | | | keep: - remove bootconfig parameter passing feature (unused). - unifdef __PROG32 and remove all remains of arm26 code. - remove ARMFPE support (unused). - remove support for ARM2, ARM2AS, ARM3, ARM6, ARM7, ARM7TDMI and StrongARM processor families, and the related silicon bug workarounds (especially the SA-110 STM^ bug). - remove cpu_functions no longer necessary after previous removals. - remove ARM32_DISABLE_ALIGNMENT_FAULTS option (unused). - make FIQ support conditional on option FIQ (unused, but may be eventually). Discussed with drahn@ and jasper@ long ago, I was sitting on this commit for no good reason.
* Provide namespace-safe alignment macros in <machine/_types.h>, withguenther2011-09-082-16/+20
| | | | | | | | 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@
* Make the INT_FAST*_{MIN,MAX} macros match the types they're defined to.guenther2011-09-081-1/+13
| | | | | | | | 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@

* machdep.kbdreset enables a shutdown by Ctrl-Alt-Del on amd64 andnaddy2011-06-241-3/+3
| | | | | | | | | | | | | | | 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@
* Also enclose variable names with external linkage in __BEGIN_DECLS.martynas2011-05-251-1/+3
| | | | | | | Doesn't matter much since C++ ABI used by GCC doesn't mangle variable names; however technically is required by Section 7.5 of the C++ spec. Discussed with/OK guenther@, matthew@.

* Change va_arg and va_end definitions from object-like macros tomatthew2011-03-021-3/+3
| | | | | | | function-like macros. Allows (questionable but legal) use of "va_arg" as a local variable name in code that includes <stdarg.h>. "seems right" deraadt@
* Introduce pmap_uncache_page(), created from the guts of pmap_kenter_cache()miod2011-01-041-1/+2

* Kill pmap_phys_address(), and force every driver's mmap() routine to returnmiod2010-12-261-3/+1
| | | | | | | a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument]. This allows MI drivers to implement mmap() routines without having to know about the pmap_phys_address() implementation and #ifdef obfuscation.
* Convert netisr to a normal soft interrupt instead of hanving MD codeclaudio2010-12-211-6/+1

* Change the signature of PMAP_PREFER from void PMAP_PREFER(..., vaddr_t *) tomiod2010-12-061-2/+2
| | | | | | vaddr_t PMAP_PREFER(..., vaddr_t). This allows better compiler optimization when the function is inlined, and avoids accessing memory on architectures when we can pass function arguments in registers.
* Introduce a new pci routine, pci_conf_size(), which returns the size of amiod2010-12-041-1/+4
