* Fix include directories for crossbuilding.Marcel Moolenaar2000-12-131-1/+1
| | | | | | | | | | | | | | | | | aicasm is run on the build machine and therefore needs to be compiled and linked against the headers and libraries (resp) of the build machine. Since normally the default include directories are search after any specified on the command line, make sure we don't accidentally pick up machine dependent headers from the kernel compile directory by specifying /usr/include first. This solves the (cross) build problem for ia64. Approved by: gibbs Notes: svn path=/head/; revision=70000
* - Add a new flag MTX_QUIET that can be passed to the various mtx_*John Baldwin2000-12-134-126/+205
| | | | | | | | | | | | | functions. If this flag is set, then no KTR log messages are issued. This is useful for blocking excessive logging, such as with the internal mutex used by the witness code. - Use MTX_QUIET on all of the mtx_enter/exit operations on the internal mutex used by the witness code. - If we are in a panic, don't do witness checks in witness_enter(), witness_exit(), and witness_try_enter(), just return.

| | | | | | | | | | | | | Generate a version string that looks just like a real Linux one - almost :) Use sbufs everywhere instead of sprintf(). Note that this is still imperfect, as the code does not check whether the sbuf overflowed - but it'll still work better than before, since if the sbuf overflows, the code now simply copies out 0 bytes instead of causing a trap (or worse, corrupting kernel structures) Notes: svn path=/head/; revision=69995

* Introduce a new potientially cleaner interface for accessing per-cpuJake Burkholder2000-12-1322-275/+292
| | | | | | | | | | | | | | variables from i386 assembly language. The syntax is PCPU(member) where member is the capitalized name of the per-cpu variable, without the gd_ prefix. Example: movl %eax,PCPU(CURPROC). The capitalization is due to using the offsets generated by genassym rather than the symbols provided by linking with globals.o. asmacros.h is the wrong place for this but it seemed as good a place as any for now. The old implementation in asnames.h has not been removed because it is still used to de-mangle the symbols used by the C variables for the UP case. Notes: svn path=/head/; revision=69971

* Preventing runaway kernel soft updates memory, take three.Kirk McKusick2000-12-134-73/+168
| | | | | | | | | | | | | | | | | | | | | | | | Previously, the syncer process was the only process in the system that could process the soft updates background work list. If enough other processes were adding requests to that list, it would eventually grow without bound. Because some of the work list requests require vnodes to be locked, it was not generally safe to let random processes process the work list while they already held vnodes locked. By adding a flag to the work list queue processing function to indicate whether the calling process could safely lock vnodes, it becomes possible to co-opt other processes into helping out with the work list. Now when the worklist gets too large, other processes can safely help out by picking off those work requests that can be handled without locking a vnode, leaving only the small number of requests requiring a vnode lock for the syncer process. With this change, it appears possible to keep even the nastiest workloads under control. Submitted by: Paul Saab <ps@yahoo-inc.com> Notes: svn path=/head/; revision=69967

* Updates to match changes elsewhere in the PCI subsystem:Mike Smith2000-12-133-98/+34
| | | | | | | | | | | | - Remove redundant header-type-specific support in the cardbus pcibus clone. The bridges don't need this anymore. - Use pcib_get_bus instead of the deprecated pci_get_secondarybus. - Implement read/write ivar support for the pccbb, and teach it how to report its secondary bus number. Save the subsidiary bus number as well, although we don't use it yet. Notes: svn path=/head/; revision=69954
* Next round of PCI subsystem updates:Mike Smith2000-12-139-1033/+931
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Break out the /dev/pci driver into a separate file. - Kill the COMPAT_OLDPCI support. - Make the EISA bridge attach a bit more like the old code; explicitly check for the existence of eisa0/isa0 and only attach if they don't already exist. Only make one bus_generic_attach() pass over the bridge, once both busses are attached. Note that the stupid Intel bridge's class is entirely unpredictable. - Add prototypes and re-layout the core PCI modules in line with current coding standards (not a major whitespace change, just moving the module data to the top of the file). - Remove redundant type-2 bridge support from the core PCI code; the PCI-CardBus code does this itself internally. Remove the now entirely redundant header-class-specific support, as well as the secondary and subordinate bus number fields. These are bridge attributes now. - Add support for PCI Extended Capabilities. - Add support for PCI Power Management. The interface currently allows a driver to query and set the power state of a device. - Add helper functions to allow drivers to enable/disable busmastering and the decoding of I/O and memory ranges. - Use PCI_SLOTMAX and PCI_FUNCMAX rather than magic numbers in some places. - Make the PCI-PCI bridge code a little more paranoid about valid I/O and memory decodes. - Add some more PCI register definitions for the command and status registers. Correct another bogus definition for type-1 bridges. Notes: svn path=/head/; revision=69953
