2013-03-12Fix kernel profiling on MP systems by using per-CPU buffers and teachMartin Pieuchot
kgmon(8) to deal with them, this time without public header changes. Previously various CPUs were iterating over the same global buffer at the same time to modify it and never ended. This diff includes some ideas submited by Thor Simon to NetBSD via miod@. ok deraadt@, mikeb@, haesbaert@

ARMv7 support. ok miod@
2013-01-18Update the ARM CPU ID information. The IDs aren't vendor/productPatrick Wildt
specific, they are specific to the ARM CPUs themselves. ok bmercer@ jsg@ deraadt@

2012-12-02Determine whether we're currently on the alternative signal stackPhilip Guenthe
dynamically, by comparing the stack pointer against the altstack base and size, so that you get the correct answer if you longjmp out of the signal handler, as tested by regress/sys/kern/stackjmp/. Also, fix alt stack handling on vax, where it was completely broken. Testing and corrections by miod@, krw@, tobiasu@, pirofti@
2012-09-11Remove the 'OLF method' used for the transition from a.out to ELF andTheo de Raadt
for all the compat layers which are now gone. Linux compat still works because it always used another method in any case, and nothing looks at p_os anymore. ok jsing

2012-08-22Convert cpp | as rules in bsd.lib.mk and lib/libc/sys/Makefile.inc to pure ccPascal Stumpf
invocations. This allows us to use the compiler builtin define __PIC__ to check for PIC/PIEness rather than passing -DPIC. Simplifies PIE work a lot. ok matthew@, conceptually ok kurt@
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.
2012-03-26Add APM_IOC_HIBERNATETheo de Raadt

2011-10-27Specify the TLS variant for each platform.Philip Guenthe
2011-10-24Introduce a pluggable interrupt controller infrastructure for beagle,Dale Rahn
to allow panda to share the port.
2011-10-19API change to initarm to pass arguments from the bootloader thru to MDDale Rahn
C code. Will be used on beagle to process machine id and atags. Looked at by uwe@, tested on beagle/armish/zaurus.
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.
2011-09-21Rename pmap_procwr() to pmap_proc_iflush() to get the intended behaviour.Miod Vallat
2011-09-20Late spring cleaning of the arm code for old dusty bits we do not want toMiod Vallat
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.
2011-09-08Provide namespace-safe alignment macros in <machine/_types.h>, withPhilip Guenthe
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@

2011-06-24machdep.kbdreset enables a shutdown by Ctrl-Alt-Del on amd64 andChristian Weisgerber
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@
2011-05-25Also enclose variable names with external linkage in __BEGIN_DECLS.Martynas Venckus
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@.

2011-03-02Change va_arg and va_end definitions from object-like macros toMatthew Dempsky
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@
2011-01-04Introduce pmap_uncache_page(), created from the guts of pmap_kenter_cache()Miod Vallat
to make a page uncached and maintain this both at the pte and pv list level, and make pmap_kenter_cache() use it. ok drahn@
2010-12-26Kill pmap_phys_address(), and force every driver's mmap() routine to returnMiod Vallat
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.
2010-12-21Convert netisr to a normal soft interrupt instead of hanving MD codeClaudio Jeker
for it. This makes the netisr a real C function which will help further development. No noticable performance change on i386 and amd64. With input from kettenis@ and miod@ additional OKs mikeb@ and henning@
2010-12-15oops, i forgot to check in the BRKSIZ define in uvm, but deraadt thinksTed Unangst
its better as a per arch MD define anyway. all default to MAXDSIZ as before.
2010-12-06Change the signature of PMAP_PREFER from void PMAP_PREFER(..., vaddr_t *) toMiod Vallat
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.
2010-12-04Introduce a new pci routine, pci_conf_size(), which returns the size of aMiod Vallat
given pcitag_t configuration address space. Currently, all pci controllers will return the usual 0x100 bytes of PCI configuration space, but this will eventually change on PCIe-capable controlers. ok kettenis@

2010-11-28Get rid of machdep.debug, machdep.booted_device and machdep.booted_kernelMiod Vallat
sysctl. Only the first one is really implemented, and it only matters on older processor flavours we don't run on (and don't want to), so this was just dead weight.
2010-11-27Get rid of the global pmap list and related debug code. While there, mergeMiod Vallat
pmap_pinit() into pmap_create(). Help and ok drahn@
2010-11-27Remove ddb single-step load and store counters. Most platforms do notMiod Vallat
