* Time has run from the "run GEOM in userland" harness, and the new regressionPoul-Henning Kamp2003-04-131-11/+0
| | | | | | | | | | test is built to test GEOM as running in the kernel. This commit is basically "unifdef -D_KERNEL" to remove the mainly #include related code to support the userland-harness. Notes: svn path=/head/; revision=113432

Add a flag argument to g_call_me() methods which will be used to signal cancellation of events in the future. This commit should be a no-op. Notes: svn path=/head/; revision=112988

* Implement a handle for efficient implementation of perforations inPoul-Henning Kamp2003-02-121-3/+6
| | | | | | | | | | | | | | | | lower extremities. Setting bit 4 in debugflags (sysctl kern.geom.debugflags=16) will allow any open to succeed on rank#1 providers. This will generally correspond to the physical disk devices: ad0, da0, md0 etc. This fundamentally violates the mechanics of GEOMs autoconfiguration, and is only provided as a debugging facility, so obviously error reports on GEOM where this bit is or has been set will not be accepted. Notes: svn path=/head/; revision=110759
* Move the g_stat struct to its own .h file, we will export it to other code.Poul-Henning Kamp2003-02-081-3/+7
| | | | | | | | | | | | | | | | | | | | | Insted of embedding a struct g_stat in consumers and providers, merely include a pointer. Remove a couple of <sys/time.h> includes now unneeded. Add a special allocator for struct g_stat. This allocator will allocate entire pages and hand out g_stat functions from there. The "id" field indicates free/used status. Add "/dev/geom.stats" device driver whic exports the pages from the allocator to userland with mmap(2) in read-only mode. This mmap(2) interface should be considered a non-public interface and the functions in libgeom (not yet committed) should be used to access the statistics data. Notes: svn path=/head/; revision=110541
* Commit the correct copy of the g_stat structure.Poul-Henning Kamp2003-02-071-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add debug.sizeof.g_stat sysctl. Set the id field of the g_stat when we create consumers and providers. Remove biocount from consumer, we will use the counters in the g_stat structure instead. Replace one field which will need to be atomically manipulated with two fields which will not (stat.nop and stat.nend). Change add companion field to bio_children: bio_inbed for the exact same reason. Don't output the biocount in the confdot output. Fix KASSERT in g_io_request(). Add sysctl kern.geom.collectstats defaulting to off. Collect the following raw statistics conditioned on this sysctl: for each consumer and provider { total number of operations started. total number of operations completed. time last operation completed. sum of idle-time. for each of BIO_READ, BIO_WRITE and BIO_DELETE { number of operations completed. number of bytes completed. number of ENOMEM errors. number of other errors. sum of transaction time. } } API for getting hold of these statistics data not included yet.

* Introduce the concept of "magic spaces", and implement them in most ofPoul-Henning Kamp2002-05-211-0/+33
| | | | | | | | | | | | | | | | | | | the relevant classes. Some methods may implement various "magic spaces", this is reserved or magic areas on the disk, set a side for various and sundry purposes. A good example is the BSD disklabel and boot code on i386 which occupies a total of four magic spaces: boot1, the disklabel, the padding behind the disklabel and boot2. The reason we don't simply tell people to write the appropriate stuff on the underlying device is that (some of) the magic spaces might be real-time modifiable. It is for instance possible to change a disklabel while partitions are open, provided the open partitions do not get trampled in the process. Sponsored by: DARPA & NAI Labs.

test and play with this. This is not yet production quality and should be run only on dedicated test boxes. For people who want to develop transformations for GEOM there exist a set of shims to run geom in userland (ask phk@freebsd.org).
