| 46 | * How it works: | |
| 47 | * ------------- | |
| 48 | * The framelist / Transfer descriptor / Queue Heads are similar like | |
| 49 | * in the linux usb_uhci.c. | |
| 50 | * | |
| 51 | * During initialization, the following skeleton is allocated in init_skel: | |
| 52 | * | |
| 53 | * framespecific | common chain | |
| 54 | * | |
| 55 | * framelist[] | |
| 56 | * [ 0 ]-----> TD ---------\ | |
| 57 | * [ 1 ]-----> TD ----------> TD ------> QH -------> QH -------> QH ---> NULL | |
| 58 | * ... TD ---------/ | |
| 59 | * [1023]-----> TD --------/ | |
| 60 | * | |
| 61 | * ^^ ^^ ^^ ^^ ^^ | |
| 62 | * 7 TDs for 1 TD for Start of Start of End Chain | |
| 63 | * INT (2-128ms) 1ms-INT CTRL Chain BULK Chain | |
| 64 | * | |
| 65 | * | |
| 66 | * Since this is a bootloader, the isochronous transfer descriptor have been removed. | |
| 67 | * | |
| 68 | * Interrupt Transfers. | |
| 69 | * -------------------- | |
| 70 | * For Interupt transfers USB_MAX_TEMP_INT_TD Transfer descriptor are available. They | |
| 71 | * will be inserted after the appropriate (depending the interval setting) skeleton TD. | |
| 72 | * If an interrupt has been detected the dev->irqhandler is called. The status and number | |
| 73 | * of transfered bytes is stored in dev->irq_status resp. dev->irq_act_len. If the | |
| 74 | * dev->irqhandler returns 0, the interrupt TD is removed and disabled. If an 1 is returned, | |
| 75 | * the interrupt TD will be reactivated. | |
| 76 | * | |
| 77 | * Control Transfers | |
| 78 | * ----------------- | |
| 79 | * Control Transfers are issued by filling the tmp_td with the appropriate data and connect | |
| 80 | * them to the qh_cntrl queue header. Before other control/bulk transfers can be issued, | |
| 81 | * the programm has to wait for completion. This does not allows asynchronous data transfer. | |
| 82 | * | |
| 83 | * Bulk Transfers | |
| 84 | * -------------- | |
| 85 | * Bulk Transfers are issued by filling the tmp_td with the appropriate data and connect | |
| 86 | * them to the qh_bulk queue header. Before other control/bulk transfers can be issued, | |
| 87 | * the programm has to wait for completion. This does not allows asynchronous data transfer. | |
