irq handler in DRM(irq_install). Modify all drivers to ensure irq
handler is removed before cleanup and cleanup is called at takedown.
Remove unused buffer private struct fields in i810, i830. Check for
lock on init/cleanup in all drivers except i810/i830. The current DDX
for i810 and i830 doesn't hold the lock on kernel init (FIXME?).
Whitwell).
- Major rework of the 2D i830/i845G support, including:
- Improve VESA mode selection, and fix refresh rate selection.
- Don't duplicate functions provided in the vbe modules.
- Don't duplicate functions provided in the vgahw module.
- Rewrite memory allocation.
- Rewrite initialisation and save/restore state handling.
- Decouple the i810 support from i830 and later.
- Remove various unnecessary hacks and workarounds.
- Fix an 845G problem with the ring buffer not in pre-allocated memory.
- Fix screen blanking.
- Fix some HW cursor glitches, and turn HW cursor off at VT switch and
exit.
- Don't attempt to use the i830's function 1 entity.
- Fix problems with option handling. (David Dawes).
- Add mode VBE-aware mode handling functions to the vbe module (David
Dawes).
