This file details changes in 2.6 which affect PCMCIA card driver authors: * event handler initialization in struct pcmcia_driver (as of 2.6.13) The event handler is notified of all events, and must be initialized as the event() callback in the driver's struct pcmcia_driver. * pcmcia/version.h should not be used (as of 2.6.13) This file will be removed eventually. * in-kernel device<->driver matching (as of 2.6.13) PCMCIA devices and their correct drivers can now be matched in kernelspace. See 'devicetable.txt' for details. * Device model integration (as of 2.6.11) A struct pcmcia_device is registered with the device model core, and can be used (e.g. for SET_NETDEV_DEV) by using handle_to_dev(client_handle_t * handle). * Convert internal I/O port addresses to unsigned long (as of 2.6.11) ioaddr_t should be replaced by kio_addr_t in PCMCIA card drivers. * irq_mask and irq_list parameters (as of 2.6.11) The irq_mask and irq_list parameters should no longer be used in PCMCIA card drivers. Instead, it is the job of the PCMCIA core to determine which IRQ should be used. Therefore, link->irq.IRQInfo2 is ignored. * client->PendingEvents is gone (as of 2.6.11) client->PendingEvents is no longer available. * client->Attributes are gone (as of 2.6.11) client->Attributes is unused, therefore it is removed from all PCMCIA card drivers * core functions no longer available (as of 2.6.11) The following functions have been removed from the kernel source because they are unused by all in-kernel drivers, and no external driver was reported to rely on them: pcmcia_get_first_region() pcmcia_get_next_region() pcmcia_modify_window() pcmcia_set_event_mask() pcmcia_get_first_window() pcmcia_get_next_window() * device list iteration upon module removal (as of 2.6.10) It is no longer necessary to iterate on the driver's internal client list and call the ->detach() function upon module removal. * Resource management. (as of 2.6.8) Although the PCMCIA subsystem will allocate resources for cards, it no longer marks these resources busy. This means that driver authors are now responsible for claiming your resources as per other drivers in Linux. You should use request_region() to mark your IO regions in-use, and request_mem_region() to mark your memory regions in-use. The name argument should be a pointer to your driver name. Eg, for pcnet_cs, name should point to the string "pcnet_cs". * CardServices is gone CardServices() in 2.4 is just a big switch statement to call various services. In 2.6, all of those entry points are exported and called directly (except for pcmcia_report_error(), just use cs_error() instead). * struct pcmcia_driver You need to use struct pcmcia_driver and pcmcia_{un,}register_driver instead of {un,}register_pccard_driver
