/******************************Module*Header*******************************\
|
|
* Module Name: bltm64.c
|
|
*
|
|
* Contains the low-level memory-mapped I/O blt functions for the Mach64.
|
|
*
|
|
* Hopefully, if you're basing your display driver on this code, to
|
|
* support all of DrvBitBlt and DrvCopyBits, you'll only have to implement
|
|
* the following routines. You shouldn't have to modify much in
|
|
* 'bitblt.c'. I've tried to make these routines as few, modular, simple,
|
|
* and efficient as I could, while still accelerating as many calls as
|
|
* possible that would be cost-effective in terms of performance wins
|
|
* versus size and effort.
|
|
*
|
|
* Note: In the following, 'relative' coordinates refers to coordinates
|
|
* that haven't yet had the offscreen bitmap (DFB) offset applied.
|
|
* 'Absolute' coordinates have had the offset applied. For example,
|
|
* we may be told to blt to (1, 1) of the bitmap, but the bitmap may
|
|
* be sitting in offscreen memory starting at coordinate (0, 768) --
|
|
* (1, 1) would be the 'relative' start coordinate, and (1, 769)
|
|
* would be the 'absolute' start coordinate'.
