|
* - Initialize the FBP floorsweeping status in fuse to 0xE1 by writing to fuse
|
|
* register fuse_status_opt_fbp_r().
|
|
* - Initialize the maximum number of FBPs to 8 by writing to Top register

|
|
* - Call nvgpu_fbp_init_support to initialize g->fbp.
|
|
* - Read the g->fbp->max_fbp_count using nvgpu_fbp_get_max_fbps_count().
|
|
* - Check if the max_fbps_count is initialized and read back correctly.
|
|
* - Read the g->fbp->fbp_en_mask using nvgpu_fbp_get_fbp_en_mask().
|
|
* - Check if the FBP en_mask is calculated correctly and read back right too.
|
|
* - Initialize the FBP floorsweeping status in fuse to 5(Use different value
|
|
* than before to check if init occurs once.
|
|
* - Call fbp_init_support again to ensure the initialization is done once.
|
|
* - Check if the max_fbps_count is NOT set to new value(5).
|
|
*
|

* Output:
