interface border, so that other serial interfaces can be attached to the
ms/kbd. zero functional changes and mostly involves moving code around
a bit. tested on the SS2.
this is necessary to attach the PCI ultrasparc keyboard/mouse drivers.
firmware sets the "stdin" property of /chosen to be a pseudo-hid (yes, they
even spell it incorrectly) that merges all keyboard input into one stream,
so we can't find the USB controller we're attached to. Instead, just give
it to the first USB keyboard found during autoconfiguration. So that we
have SOMETHING available early on, use OpenFirmware i/o to do keyboard
input to the console wsdisplay until the USB code attaches the keyboard.
From Jason Thorpe <thorpej@nas.nasa.gov>
the child inherits the stack pointer from the parent (traditional
behavior). Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.
This is required for clone(2).
netbooting on machines that can't netboot a fullsize kernel.
This is only a stop-gap solution until the pmax gets a working two stage
netboot, and is not enabled by default.
which set the LDT and share VM space (e.g. new versions of WINE) expect
the LDT to be logically coupled to the address space. Use the new pmap_fork()
interface to copy non-shared user-set LDTs when the address space is forked.
unaligned access handler and clean it up some. Add support for emulating
the BWX instructions (ld{b,w}u, st{b,w}, sext{b,w}), which user software
can expect to be emulated. (Thanks, Alpha Architecture!)
register names was confusing, and could not _be_ correct in some cases.
Also, add a couple of 'generic' instruction formats which should be used
when decoding instructions before the specific format is known.
so that devices which must allocate DMA memory in this range (e.g.
PixelStamp graphics boards) have a better chance of doing so, without
an awful hack.
_splraise, _spllower, _splset, _splget, _setsoftintr, _clrsoftintr, _splnone.
They manipulate MIPS processor's 8 interrupt sources and are used
as building blocks for NetBSD spl(9) kernel interface. Note that
MIPS processor doesn't enforce inclusive 'interrupt levels' found
in other processors, then the hierarchal nature of IPL must be
implemented by composing MIPS processor interrupt masks appropriately.
With the simplest target port in which small number of devices are
independently assigned with 6 external interrupt signal lines,
spl(9) kernel interface will be implemented with #define's of
processor interrupt controls mentioned above. In more general
cases, in which target computers have many devices and 'system
registers' indicating pending interrupt sources at any moment,
spl(9) will be implemented with more complex machinary manipulating
processor interrupts and system registers in target port dependent
ways.
- Nuke unused code and reorder locore definitions. XXX Following
routines will be replaced with C language version; setrunqueue,
remrunqueue, switchfpregs, savefpregs, MachFPInterrupt.
the console. New algorithm:
* if stdin == keyboard, and parent of keyboard == adb, use ADB.
* else, must be a USB keyboard. Search backwards though the parents
until the USB controller is located. Determine its location in the PCI
domain, and which type of controller it is, and tell that controller that
it has the console input device. The USB code will then attach the first
USB keyboard as the console input device during autoconfiguration.
The iMac and Blue and White G3 consoles are fully functional now!
