* MFC r196508:Ed Schouten2009-08-281-15/+11
| | | | | | | | | | | | | | | | | | | | | | | | | Our implementation of granpt(3) could be valid in the future. When I wrote the pseudo-terminal driver for the MPSAFE TTY code, Robert Watson and I agreed the best way to implement this, would be to let posix_openpt() create a pseudo-terminal with proper permissions in place and let grantpt() and unlockpt() be no-ops. This isn't valid behaviour when looking at the spec. Because I thought it was an elegant solution, I filed a bug report at the Austin Group about this. In their last teleconference, they agreed on this subject. This means that future revisions of POSIX may allow grantpt() and unlockpt() to be no-ops if an open() on /dev/ptmx (if the implementation has such a device) and posix_openpt() already do the right thing. I'd rather put this in the manpage, because simply mentioning we don't comply to any standard makes it look worse than it is. Right now we don't, but at least we took care of it.

If we cannot resolve a symbol try to see if we can find it with prefix of the virtualized subsystem, currently only "vnet_entry" by identifying either the vnet of the current process for a live system or the vnet of proc0 (or of dumptid if compiled in a non-default way). The way this is done currently allows us to only touch libkvm but no single application. Once we are going to virtualize more subsystems we will have to review this decision for better scaling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | modularize it so that new transports can be created. Add a transport for SATA Add a periph+protocol layer for ATA Add a driver for AHCI-compliant hardware. Add a maxio field to CAM so that drivers can advertise their max I/O capability. Modify various drivers so that they are insulated from the value of MAXPHYS. The new ATA/SATA code supports AHCI-compliant hardware, and will override the classic ATA driver if it is loaded as a module at boot time or compiled into the kernel. The stack now support NCQ (tagged queueing) for increased performance on modern SATA drives. It also supports port multipliers. ATA drives are accessed via 'ada' device nodes. ATAPI drives are accessed via 'cd' device nodes. They can all be enumerated and manipulated via camcontrol, just like SCSI drives. SCSI commands are not translated to their ATA equivalents; ATA native commands are used throughout the entire stack, including camcontrol. See the camcontrol manpage for further details. Testing this code may require that you update your fstab, and possibly modify your BIOS to enable AHCI functionality, if available. This code is very experimental at the moment. The userland ABI/API has changed, so applications will need to be recompiled. It may change further in the near future. The 'ada' device name may also change as more infrastructure is completed in this project. The goal is to eventually put all CAM busses and devices until newbus, allowing for interesting topology and management options. Few functional changes will be seen with existing SCSI/SAS/FC drivers, though the userland ABI has still changed. In the future, transports specific modules for SAS and FC may appear in order to better support the topologies and capabilities of these technologies. The modularization of CAM and the addition of the ATA/SATA modules is meant to break CAM out of the mold of being specific to SCSI, letting it grow to be a framework for arbitrary transports and protocols. It also allows drivers to be written to support discrete hardware without jeopardizing the stability of non-related hardware. While only an AHCI driver is provided now, a Silicon Image driver is also in the works. Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware is possible and encouraged. Help with new transports is also encouraged. Submitted by: scottl, mav Approved by: re Notes: svn path=/head/; revision=195534
