Abstract:
|
|
|
|
Bitmap display support with text mode for
|
|
upgrade. This file has implementation for the
|
|
three core abstractions i.e. Bitmap,
|
|
Animated bitmap and Graphics Progress bar.
|
|
|
|
In upgrade graphics mode, we have one primary
|
|
graphics thread running in the foreground.
|
|
This thread paints the background, creates
|
|
animated bitmap(s) and updates a single
|
|
progress bar. An upgrade specific callback
|
|
is registered which calculates the overall
|
|
progress.
|
|
|
|
Although we are in graphics mode during upgrade,
|
|
all the regular textmode output is still
|
|
written to a buffer. When we hit some error
|
|
or require user intervention we switch back
|
|
to the actual textmode and copy all the cached
|
|
information to actual video memory. One can
|
|
switch to textmode from graphics but not
|
|
vice-versa.
|
|
|
|
Note : For each animated bitmap a separate
|
|
thread is started while animating. Using lot
|
|
of animated bitmaps can slow down the actual
|
|
text mode setup thread.
