| | | | | | | | | | | | | | | | | | | | | | | | | | | Allow interrupt driven config hooks to be registered from config hook callbacks. Interrupt driven configuration hooks serve two purposes: they are a mechanism for registering for a callback that is invoked once interrupt services are available, and they hold off root device selection so long as any configuration hooks are still active. Before this change, it was not possible to safely register additional hooks from the context of a configuration hook callback. The need for this feature arises when interrupts are required to discover new devices (e.g. access to the XenStore to find para-virtualized devices) which in turn also require the ability to hold off root device selection until some lengthy, interrupt driven, configuration task has completed (e.g. Xen front/back device driver negotiation). More specifically, the mutex protecting the list of active configuration hooks is never held during a callback, and static information is used to ensure proper ordering and only a single callback to each hook even when faced with registration or removal of a hook during an active run.

* Merge MIPS platform support to 8-STABLE.Jayachandran C.2010-11-273-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit merges the MIPS platform changes that was now stable in -CURRENT into 8-STABLE. The MIPS changesets are too many (~400) to list here. But the changesets merged in this commit that affect other platforms are summarized below: r204635 : (changes to sys/dev/hwpmc, lib/libpmc, sys/sys/pmc.h) Add support for hwpmc(4) on the MIPS 24K, 32 bit, embedded processor. r205845: (changes to sys/modules/Makefile) Fix for building modules on mips and arm. r204031: (changes to sys/kern/link_elf_obj.c) printf fix, as part of kernel module support for MIPS. r206404: (changes to sys/arm/include/bus.h) Add BUS_SPACE_UNRESTRICTED and define it to be ~0, just like all the other platforms - for arm and mips. r206819: (changes to sys/vm/) Add VMFS_TLB_ALIGNED_SPACE option and kmem_alloc_nofault_space(), which is used to allocate kernel stack address on MIPS. r208165, r211087: (sys/kern/subr_smp.c, sys/kern/sched_ule.c) Enable ULE scheduler for MIPS, Fix for an issue in SMP when 32 cpus are enabled. r208659: (sys/{ia64/ia64,mips/mips,sun4v/sun4v}/pmap.c) Simplify the inner loop of get_pv_entry() r208794: (changes to sys/vm/) Make vm_contig_grow_cache() extern, and use it when vm_phys_alloc_contig() fails to allocate MIPS page table pages. r210327: (changes to sys/vm/) Support for MIPS page table page allocation. Add a new function 'vm_page_t vm_page_alloc_freelist(int flind, int order, int req)' to vm/vm_page.c to allocate a page from a specified freelist, and other related changes.

| | | | | | | | | | | | | | | | | Improve bufdone_finish()'s handling of the bogus page. Specifically, if one or more mappings to the bogus page must be replaced, call pmap_qenter() just once. Previously, pmap_qenter() was called for each mapping to the bogus page. MFC r209902 Change the implementation of vm_hold_free_pages() so that it performs at most one call to pmap_qremove(), and thus one TLB shootdown, instead of one call and TLB shootdown per page. Simplify the interface to vm_hold_free_pages(). Notes: svn path=/stable/8/; revision=213890
