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 |
