115 | * To write a force-feedback-capable driver, the upload_effect | ||
116 | * and erase_effect callbacks in input_dev must be implemented. | ||
117 | * The uinput driver will generate a fake input event when one of | ||
118 | * these callbacks are invoked. The userspace code then uses | ||
119 | * ioctls to retrieve additional parameters and send the return code. | ||
120 | * The callback blocks until this return code is sent. | ||
121 | * | ||
122 | * The described callback mechanism is only used if ff_effects_max | ||
123 | * is set. | ||

126 | * 1. Wait for an event with type == EV_UINPUT and code == UI_FF_UPLOAD. | ||
127 | * A request ID will be given in 'value'. | ||
128 | * 2. Allocate a uinput_ff_upload struct, fill in request_id with | ||
129 | * the 'value' from the EV_UINPUT event. | ||
130 | * 3. Issue a UI_BEGIN_FF_UPLOAD ioctl, giving it the | ||
131 | * uinput_ff_upload struct. It will be filled in with the | ||
132 | * ff_effects passed to upload_effect(). | ||
133 | * 4. Perform the effect upload, and place a return code back into | ||
134 | the uinput_ff_upload struct. | ||
135 | * 5. Issue a UI_END_FF_UPLOAD ioctl, also giving it the | ||
136 | * uinput_ff_upload_effect struct. This will complete execution | ||
137 | * of our upload_effect() handler. | ||

139 | * To implement erase_effect(): | ||
140 | * 1. Wait for an event with type == EV_UINPUT and code == UI_FF_ERASE. | ||
141 | * A request ID will be given in 'value'. | ||
142 | * 2. Allocate a uinput_ff_erase struct, fill in request_id with | ||
143 | * the 'value' from the EV_UINPUT event. | ||
144 | * 3. Issue a UI_BEGIN_FF_ERASE ioctl, giving it the | ||
145 | * uinput_ff_erase struct. It will be filled in with the | ||
