* Fix the creation of EFI images that got broken by the import ofMarcel Moolenaar2004-07-204-6/+6
| | | | | | | | | | | | binutils 2.15. The linker now creates a .rela.dyn section for dynamic relocations, while our script created a .rela section. Likewise, we copied the .rela section to the EFI image, but not the .rela.dyn section. The fix is to rename .rela to .rela.dyn in the linker script so that all relocations end up in the same section again. This we copy into the EFI image. Notes: svn path=/head/; revision=132435

* Fix printing of long doubles to match the size thatAndrew Gallatin2004-07-191-9/+9
| | | | | | | | | | | | | | | | gcc is using. This fixes devstat consumers (like vmstat, iostat, systat) so they don't print crazy zillion digit numbers for disk transfers and bandwidth. According to gcc, long doubles are 64-bits, rather than 128 bits like the SVR4 ABI spec wants them to be.. Note that MacOSX also treats long doubles as 64-bits, and not 128 bits, so we are in good company. Reviewed by: das Approved by: grehan Notes: svn path=/head/; revision=132421

| | | | | | | | | | | | | | | | allocated as "no object" pages. Similar changes were made to the amd64 and i386 pmap last year. The primary reason being that maintaining a pte object leads to lock order violations. A secondary reason being that the pte object is redundant, i.e., the page table itself can be used to lookup page table pages. (Historical note: The pte object predates our ability to allocate "no object" pages. Thus, the pte object was a necessary evil.) - Unconditionally check the vm object lock's status in vm_page_remove(). Previously, this assertion could not be made on Alpha due to its use of a pte object. Notes: svn path=/head/; revision=132414

* Reimplement contigmalloc(9) with an algorithm which stands a greatly-Brian Feldman2004-07-194-63/+322
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | improved chance of working despite pressure from running programs. Instead of trying to throw a bunch of pages out to swap and hope for the best, only a range that can potentially fulfill contigmalloc(9)'s request will have its contents paged out (potentially, not forcibly) at a time. The new contigmalloc operation still operates in three passes, but it could potentially be tuned to more or less. The first pass only looks at pages in the cache and free pages, so they would be thrown out without having to block. If this is not enough, the subsequent passes page out any unwired memory. To combat memory pressure refragmenting the section of memory being laundered, each page is removed from the systems' free memory queue once it has been freed so that blocking later doesn't cause the memory laundered so far to get reallocated. The page-out operations are now blocking, as it would make little sense to try to push out a page, then get its status immediately afterward to remove it from the available free pages queue, if it's unlikely to have been freed. Another change is that if KVA allocation fails, the allocated memory segment will be freed and not leaked. There is a sysctl/tunable, defaulting to on, which causes the old contigmalloc() algorithm to be used. Nonetheless, I have been using vm.old_contigmalloc=0 for over a month. It is safe to switch at run-time to see the difference it makes. A new interface has been used which does not require mapping the allocated pages into KVA: vm_page.h functions vm_page_alloc_contig() and vm_page_release_contig(). These are what vm.old_contigmalloc=0 uses internally, so the sysctl/tunable does not affect their operation. When using the contigmalloc(9) and contigfree(9) interfaces, memory is now tracked with malloc(9) stats. Several functions have been exported from kern_malloc.c to allow other subsystems to use these statistics, as well. This invalidates the BUGS section of the contigmalloc(9) manpage.

* After maintaining previous behaviour in writing out the core notes, it'sMarcel Moolenaar2004-07-181-8/+5
| | | | | | | | | | | | | | | | | | | | time now to break with the past: do not write the PID in the first note. Rationale: 1. [impact of the breakage] Process IDs in core files serve no immediate purpose to the debugger itself. They are only useful to relate a core file to a process. This can provide context to the person looking at the core file, provided one keeps track of this. Overall, not having the PID in the core file is only in very rare occasions unfortunate. 2. [reason of the breakage] Having one PRSTATUS note contain the PID, while all others contain the LWPID of the corresponding kernel thread creates an irregularity for the debugger that cannot easily be worked around. This is caused by libthread_db correlating user thread IDs to kernel thread (aka LWP) IDs and thus aware of the actual LWPIDs. Update comments accordingly. Notes: svn path=/head/; revision=132364

| | | | | | | | | | | | | | | | | | | | | | | | | | | that get certain types of control messages (ping6 and rtsol are examples). This gets the new code closer to working: 1) Collect control mbufs for processing in the controlp == NULL case, so that they can be freed by externalize. 2) Loop over the list of control mbufs, as the externalize function may not know how to deal with chains. 3) In the case where there is no externalize function, remember to add the control mbuf to the controlp list so that it will be returned. 4) After adding stuff to the controlp list, walk to the end of the list of stuff that was added, incase we added a chain. This code can be further improved, but this is enough to get most things working again. Reviewed by: rwatson Notes: svn path=/head/; revision=132359
