| | | | | | | | | | | | | | | | | | | the prototype-scsi_link's SDEV_2NDBUS flag rather than against its scsibus field. First, the scsibus field hasn't even been initialized when device_register() is called so it's always 0 anyway; second, the path number is supposed to be locally scoped to a single device whereas the scsibus field is a global scsibus(4) device number. The existing code only happened to work because all of the dual-port fibre-channel adapters we currently support attach as two devices with one scsibus each rather than a single device with two scsibuses, so we would never see anything but "fp@0". Initial investigation and diff by jmatthew after my SCSI cleanups at c2k11 broke sparc64's ability to boot from isp(4); newer version from me based on discussion with krw and kettenis. tested and ok kettenis

| | | | | | | | | 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.
* __tfork() needs to set the stack address of the new thread in the kernel,guenther2012-06-211-4/+8
| | | | | | | | | 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@

* Improve/clean up sparc64 installboot:jsing2012-01-013-55/+52
| | | | | | | | | | | | | | | - Use opendev() like we do for installboot on many other archs. - Use the term bootblock rather than prototype for the first-stage, since we install it verbatim. - Read the bootblock into a zeroed buffer rather than messing around with mmap() and zeroing the end of the space. - Make man page consistent with respect to the first-stage bootblock and second-stage boot program. ok kettenis@ jmc@ (for the man part)

| | | | | | | | | | | for pointing to the thread-control-block. Support for mapping this to the correct hardware register can be added as it's finished; start with support for amd64, sparc, and sparc64. Includes syscalls for getting and setting it (for a portable __errno implementation) as well as creating a new thread with an initial value for it. discussed with miod@, kettenis@, deraadt@; committing to get the syscalls in with the impending libc bump and do further refinements in tree

* Introduce pci_probe_device_hook(pci_chipset_tag_t, struct pci_attach_args *).miod2011-10-101-1/+3
| | | | | | | | | | | | | | | | | | 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.
