21 | /* The latency of the STI functions cannot really be reduced by setting | |
22 | * this to 0; STI doesn't seem to be designed to allow calling a different | |
23 | * function (or the same function with different arguments) after a | |
24 | * function exited with 1 as return value. | |
25 | * | |
26 | * As all of the functions below could be called from interrupt context, | |
27 | * we have to spin_lock_irqsave around the do { ret = bla(); } while(ret==1) | |
28 | * block. Really bad latency there. | |
29 | * | |
30 | * Probably the best solution to all this is have the generic code manage | |
31 | * the screen buffer and a kernel thread to call STI occasionally. | |
32 | * | |
33 | * Luckily, the frame buffer guys have the same problem so we can just wait | |
34 | * for them to fix it and steal their solution. prumpf | |
