/* 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
