* Update documentation for kldload(8)'s ability to load multiple modules.Juli Mallett2002-10-092-4/+6

* When creating a snapshot, create a list of initially allocated blocks.Kirk McKusick2002-10-091-7/+135
| | | | | | | | | | | | | | | Whenever doing a copy-on-write check, first look in the list of initially allocated blocks to see if it is there. If so, no further check is needed. If not, fall through and do the full check. This change eliminates one of two known deadlocks caused by snapshots. Handling the second deadlock will be the subject of another check-in. This change also reduces the cost of the copy-on-write check by speeding up the verification of frequently checked blocks. Sponsored by: DARPA & NAI Labs. Notes: svn path=/head/; revision=104698
* The appropriate units for disk block addresses are always DEV_BSIZE,Kirk McKusick2002-10-091-8/+1
| | | | | | | | | | | | | | | even when the underlying device has a larger sector size. Therefore, the filesystem code should not (and with this patch does not) try to use the underlying sector size when doing disk block address calculations. This patch fixes problems in -current when using the swap-based memory-disk device (mdconfig -a -t swap ...). This bugfix is not relevant to -stable as -stable does not have the memory-disk device.

* Convert make(1) to use ANSI style function declarations. VariableJuli Mallett2002-10-0915-771/+340
| | | | | | | | | | | | | | documentation already adequatedly existed in the description in most cases. Where it did not, it was added. If no documentation existed beforehand, then none was added. Some unused dummies for use in the traversal functions were marked as __unused during the conversion. Occasionally, local style fixes were applied to lines already being modified or influenced. Now make(1) should always build with WARNS=3. Notes: svn path=/head/; revision=104696
* Round out the facilty for a 'bound' thread to loan out its KSEJulian Elischer2002-10-0915-513/+769
| | | | | | | | | | | | | | | | | | | | | | | | | | | in specific situations. The owner thread must be blocked, and the borrower can not proceed back to user space with the borrowed KSE. The borrower will return the KSE on the next context switch where teh owner wants it back. This removes a lot of possible race conditions and deadlocks. It is consceivable that the borrower should inherit the priority of the owner too. that's another discussion and would be simple to do. Also, as part of this, the "preallocatd spare thread" is attached to the thread doing a syscall rather than the KSE. This removes the need to lock the scheduler when we want to access it, as it's now "at hand". DDB now shows a lot mor info for threaded proceses though it may need some optimisation to squeeze it all back into 80 chars again. (possible JKH project) Upcalls are now "bound" threads, but "KSE Lending" now means that other completing syscalls can be completed using that KSE before the upcall finally makes it back to the UTS. (getting threads OUT OF THE KERNEL is one of the highest priorities in the KSE system.) The upcall when it happens will present all the completed syscalls to the KSE for selection.

* Fix for the panic when using a Promise TX2.Søren Schmidt2002-10-081-16/+23
| | | | | | | | | | | | The problem is that the code does a check for the granparent of the Promise chip, if this is a bridge of the right type, we have a TX4 on our hands, and need to handle that ones "issues". Now the grandparent check cause subtle bugs in the newbus system, mainly that pci_get_devid doesn't return an error value. This patch works around the issue by using BUS_READ_IVAR() instead.
