2013-02-12Back out per-CPU kernel profiling, it shouldn't modify a public headerMartin Pieuchot
at this moment.
2013-02-11Fix kernel profiling on MP systems by using per-CPU buffer. PreviouslyMartin Pieuchot
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 mikeb@, haesbaert@
2013-02-09Do not bother defining cpu_exec_aout_makecmds() on platforms where we no longerMiod Vallat
(or never did) support a.out binaries (i.e. where _KERN_DO_AOUT is not defined).
2013-01-16cpu_coredump() also needs to invoke vn_rdwr() without IO_NODELOCKED; onlyMiod Vallat
affects a.out binaries' core dumps.
2012-12-31Remove emulation errno mapping code from platforms that no longer havePhilip Guenther
non-native emulations. ok miod@
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@

2012-10-08Revamp 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

2012-09-27remove the zlib rfc text: these pages already point to gzip(1), whichJason McIntyre
has the references, and the rfc is not that relevant anyway;
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

2012-08-28Add -nopie to LINKFLAGS on ELF architectures. Note that this needs anPascal Stumpf

built with -fno-pie. This gets the hairiest part of PIE out of the way ... ok deraadt@

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.
2012-06-21__tfork() needs to set the stack address of the new thread in the kernel,Philip Guenthe
so that it can't get a signal while still running on the parent thread's stack. Also, pass in sizeof(struct __tfork) to provide forward compat when more members are added. This is an ABI change, so switch syscall numbers and bump lib majors this time. ok deraadt@ matthew@
2012-06-05As specified in PA RISC 2.0 errata, the 16-byte alignment restriction doesJoel Sing
not apply if the coherent operation cache control completer is specified for the ldcw/ldcd instruction. As a result, remove the alignment requirement and add the necessary completer. ok kettenis@

from a fork syscall done by the parent. Use __tfork, not rfork here to match the ktrace records for the parent (CALL __tfork, RET __tfork). ok guenther

2012-02-25Fix a bad case of htole64() being used instead of htole32() when setting upMiod Vallat
pci configuration space accesses to allow proper recovery from failure, causing the measure not to have any effect and the system to freeze hard. Fixes use of pcidump -x on B1000, and probably more systems.

they apply. ok oga@ deraadt@
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.
