- * TODO:
- * - call STI in virtual mode rather than in real mode
- * - support for PCI-only STI ROMs (which don't have a traditional region
- * list)
- * - safe detection (i.e. verify there is a graphics device at a given
- * address first, not just read a random device's io space)
- * - support for multiple STI devices in one machine
- * - support for byte-mode STI ROMs
- * - support for just using STI to switch to a colour fb (stifb ?)
- * - try to make it work on m68k hp workstations ;)

-/* The latency of the STI functions cannot really be reduced by setting
- * this to 0; STI doesn't seem to be designed to allow calling a different
- * function (or the same function with different arguments) after a
- * function exited with 1 as return value.
- *
- * As all of the functions below could be called from interrupt context,
- * we have to spin_lock_irqsave around the do { ret = bla(); } while(ret==1)
- * block. Really bad latency there.
- *
- * Probably the best solution to all this is have the generic code manage
- * the screen buffer and a kernel thread to call STI occasionally.
- *
- * Luckily, the frame buffer guys have the same problem so we can just wait
- * for them to fix it and steal their solution. prumpf
- *
- * Actually, another long-term viable solution is to completely do STI
- * support in userspace - that way we avoid the potential license issues
- * of using proprietary fonts, too. */
