33 | * | ||
34 | * There are two types of timer suported: | ||
35 | * | ||
36 | * o NVGPU_TIMER_CPU_TIMER | ||
37 | * Timer uses the CPU to measure the timeout. | ||
38 | * | ||
39 | * o NVGPU_TIMER_RETRY_TIMER | ||
40 | * Instead of measuring a time limit keep track of the number of times | ||
41 | * something has been attempted. After said limit, "expire" the timer. | ||
42 | * | ||
43 | * Available flags: | ||
44 | * | ||
45 | * o NVGPU_TIMER_NO_PRE_SI | ||
46 | * By default when the system is not running on silicon the timeout | ||
47 | * code will ignore the requested timeout. Specifying this flag will | ||
48 | * override that behavior and honor the timeout regardless of platform. | ||
49 | * | ||
50 | * o NVGPU_TIMER_SILENT_TIMEOUT | ||
51 | * Do not print any messages on timeout. Normally a simple message is | ||
52 | * printed that specifies where the timeout occurred. | ||
