Update the default cvs tag for RELENG_9 by merging the following revisions: r225757 (by kensmith, partial): Shift head from 9.0-CURRENT to 10.0-CURRENT in preparation for releasing it from the 9.0-RELEASE release cycle code freeze. r225764 (by kensmith): Forgot to add "RELENG_8" to list of CVS tags. Reported by: Milan Obuch (cvs tag) Approved by: re (kib)

Add an introductory Capsicum man page providing a high-level description of its mechanisms, pointing at other pertinent man pages, and cautioning about the experimental status of Capsicum in FreeBSD. Sponsored by: Google, Inc. Approved by: re (kib)

Add the sfxge(4) device driver, providing support for 10Gb Ethernet adapters

2011-11-28T20:43:50Z

based on Solarflare SFC9000 family controllers. The driver supports jumbo frames, transmit/receive checksum offload, TCP Segmentation Offload (TSO), Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO, and Receive Side Scaling (RSS) using MSI-X interrupts. This work was sponsored by Solarflare Communications, Inc. My sincere thanks to Ben Hutchings for doing a lot of the hard work! Sponsored by: Solarflare Communications, Inc. Approved by: re (bz)

- Add a DEVMETHOD_END alias for KOBJMETHOD_END so that along with 'driver_t' and DEVMETHOD() we can fully hide the explicit mention of kobj(9) from device drivers. - Update the device driver examples to use DEVMETHOD_END. Submitted by: jhb Approved by: re (kib)

As it turns out, r186347 actually is insufficient to avoid the use of the curthread-accessing part of mtx_{,un}lock(9) when using a r210623-style curthread implementation on sparc64, crashing the kernel in its early cycles as PCPU isn't set up, yet (and can't be set up as OFW is one of the things we need for that, which leads to a chicken-and-egg problem). What happens is that due to the fact that the idea of r210623 actually is to allow the compiler to cache invocations of curthread, it factors out obtaining curthread needed for both mtx_lock(9) and mtx_unlock(9) to before the branch based on kobj_mutex_inited when compiling the kernel without the debugging options. So change kobj_class_compile_static(9) to just never acquire kobj_mtx, effectively restricting it to its documented use, and add a kobj_init_static(9) for initializing objects using a class compiled with the former and that also avoids using mutex(9) (and malloc(9)). Also assert in both of these functions that they are used in their intended way only. While at it, inline kobj_register_method() and kobj_unregister_method() as there wasn't much point for factoring them out in the first place and so that a reader of the code has to figure out the locking for fewer functions missing a KOBJ_ASSERT. Tested on powerpc{,64} by andreast. Reviewed by: nwhitehorn (earlier version), jhb Approved by: re (kib)
