|
* This system is now divided into two levels because of complications
|

|
| 1285 |
|
|
*
|
| 1286 |
|
|
* fbcon_bmove(), fbcon_clear(), fbcon_putc(), fbcon_clear_margins()

*
|
| 1288 |
|
|
* handles y values in range [0, scr_height-1] that correspond to real
|
| 1289 |
|
|
* screen positions. y_wrap shift means that first line of bitmap may be
|
| 1290 |
|
|
* anywhere on this display. These functions convert lineoffsets to
|
| 1291 |
|
|
* bitmap offsets and deal with the wrap-around case by splitting blits.
|
| 1292 |
|
|
*
|
| 1293 |
|
|
* fbcon_bmove_physical_8() -- These functions fast implementations
|
| 1294 |
|
|
* fbcon_clear_physical_8() -- of original fbcon_XXX fns.
|

|
* WARNING:
|
| 1298 |
|
|
*
|
| 1299 |
|
|
* At the moment fbcon_putc() cannot blit across vertical wrap boundary
|
| 1300 |
|

* Implies should only really hardware scroll in rows. Only reason for
|
| 1301 |
