It is possible that it is a different slot when ivtv is used in Xen, in that case I ignore this card here. The worst that can happen is that the card presents itself with a non-working radio device.

For the PVR350 this includes the decoder VSYNC interrupt, which is always on. It is not only used during decoding but also by the OSD. Some old PVR250 cards had a cx23415, so testing for that is too general. Instead test if the card has video output capability. */ if (itv->v4l2_cap & V4L2_CAP_VIDEO_OUTPUT) { ivtv_clear_irq_mask(itv, IVTV_IRQ_MASK_INIT | IVTV_IRQ_DEC_VSYNC); ivtv_set_osd_alpha(itv); } else ivtv_clear_irq_mask(itv, IVTV_IRQ_MASK_INIT); return 0; } static void ivtv_remove(struct pci_dev *pci_dev) { struct ivtv *itv = pci_get_drvdata(pci_dev); IVTV_DEBUG_INFO("Removing Card #%d\n", itv->num); if (test_bit(IVTV_F_I_INITED, &itv->i_flags)) { /* Stop all captures */ IVTV_DEBUG_INFO("Stopping all streams\n"); if (atomic_read(&itv->capturing) > 0) ivtv_stop_all_captures(itv); /* Stop all decoding */ IVTV_DEBUG_INFO("Stopping decoding\n"); if (atomic_read(&itv->decoding) > 0) { int type; if (test_bit(IVTV_F_I_DEC_YUV, &itv->i_flags)) type = IVTV_DEC_STREAM_TYPE_YUV; else type = IVTV_DEC_STREAM_TYPE_MPG; ivtv_stop_v4l2_decode_stream(&itv->streams[type], VIDEO_CMD_STOP_TO_BLACK | VIDEO_CMD_STOP_IMMEDIATELY, 0); } ivtv_halt_firmware(itv); } /* Interrupts */ ivtv_set_irq_mask(itv, 0xffffffff); del_timer_sync(&itv->dma_timer); /* Stop all Work Queues */ flush_workqueue(itv->irq_work_queues); destroy_workqueue(itv->irq_work_queues); ivtv_streams_cleanup(itv); ivtv_udma_free(itv); exit_ivtv_i2c(itv); free_irq(itv->dev->irq, (void *)itv); ivtv_iounmap(itv); release_mem_region(itv->base_addr, IVTV_ENCODER_SIZE); release_mem_region(itv->base_addr + IVTV_REG_OFFSET, IVTV_REG_SIZE); if (itv->has_cx23415) release_mem_region(itv->base_addr + IVTV_DECODER_OFFSET, IVTV_DECODER_SIZE); pci_disable_device(itv->dev); IVTV_INFO("Removed %s, card #%d\n", itv->card_name, itv->num); } /* define a pci_driver for card detection */ static struct pci_driver ivtv_pci_driver = { .name = "ivtv", .id_table = ivtv_pci_tbl, .probe = ivtv_probe, .remove = ivtv_remove, }; static int module_start(void) { printk(KERN_INFO "ivtv: Start initialization, version %s\n", IVTV_VERSION); memset(ivtv_cards, 0, sizeof(ivtv_cards)); /* Validate parameters */ if (ivtv_first_minor < 0 || ivtv_first_minor >= IVTV_MAX_CARDS) { printk(KERN_ERR "ivtv: Exiting, ivtv_first_minor must be between 0 and %d\n", IVTV_MAX_CARDS - 1); return -1; } if (ivtv_debug < 0 || ivtv_debug > 2047) { ivtv_debug = 0; printk(KERN_INFO "ivtv: Debug value must be >= 0 and <= 2047\n"); } if (pci_register_driver(&ivtv_pci_driver)) { printk(KERN_ERR "ivtv: Error detecting PCI card\n"); return -ENODEV; } printk(KERN_INFO "ivtv: End initialization\n"); return 0; } static void module_cleanup(void) { int i, j; pci_unregister_driver(&ivtv_pci_driver); spin_lock(&ivtv_cards_lock); for (i = 0; i < ivtv_cards_active; i++) { if (ivtv_cards[i] == NULL) continue; for (j = 0; j < IVTV_VBI_FRAMES; j++) { kfree(ivtv_cards[i]->vbi.sliced_mpeg_data[j]); } kfree(ivtv_cards[i]); } spin_unlock(&ivtv_cards_lock); } /* Note: These symbols are exported because they are used by the ivtvfb framebuffer module and an infrared module for the IR-blaster. */ EXPORT_SYMBOL(ivtv_set_irq_mask); EXPORT_SYMBOL(ivtv_cards_active); EXPORT_SYMBOL(ivtv_cards); EXPORT_SYMBOL(ivtv_cards_lock); EXPORT_SYMBOL(ivtv_api); EXPORT_SYMBOL(ivtv_vapi); EXPORT_SYMBOL(ivtv_vapi_result); EXPORT_SYMBOL(ivtv_clear_irq_mask); EXPORT_SYMBOL(ivtv_debug); EXPORT_SYMBOL(ivtv_reset_ir_gpio); EXPORT_SYMBOL(ivtv_udma_setup); EXPORT_SYMBOL(ivtv_udma_unmap); EXPORT_SYMBOL(ivtv_udma_alloc); EXPORT_SYMBOL(ivtv_udma_prepare); EXPORT_SYMBOL(ivtv_init_on_first_open); module_init(module_start); module_exit(module_cleanup);
