Remove special casing for running in the simulator from the kernel and instead add platform, firmware and EFI stubs to the loader. The net effect of this change is that besides a special console and disk driver, the kernel has no knowledge of the simulator. This has the following advantages: o Simulator support is much harder to break, o It's easier to make use of more feature complete simulators. This would only need a change in the simulator specific loader, o Running SMP kernels within the simulator. Note that ski at this time does not simulate IPIs, so there's no way to start APs. The platform, firmware and EFI stubs describe the following hardware: o 4 CPU Itanium, o 128 MB RAM within the 4GB address space, o 64 MB RAM above the 4GB address space. NOTE: The stubs in the skiloader describe a machine that should in parts be defined by the simulator. Things like processor interrupt block and AP wakeup vector cannot be choosen at random because they require interpretation by the simulator. Currently the simulator is ignorant of this. This change introduces an unofficial SSC call SSC_SAL_SET_VECTORS which is ignored by the simulator. Tested with: ski (version 0.943 for linux)

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.
