- This file details changes in 2.6 which affect PCMCIA card driver authors:
- * New release helper (as of 2.6.17)
- Instead of calling pcmcia_release_{configuration,io,irq,win}, all that's
- necessary now is calling pcmcia_disable_device. As there is no valid
- reason left to call pcmcia_release_io and pcmcia_release_irq, the
- exports for them were removed.
- * Unify detach and REMOVAL event code, as well as attach and INSERTION
- code (as of 2.6.16)
- void (*remove) (struct pcmcia_device *dev);
- int (*probe) (struct pcmcia_device *dev);
- * Move suspend, resume and reset out of event handler (as of 2.6.16)
- int (*suspend) (struct pcmcia_device *dev);
- int (*resume) (struct pcmcia_device *dev);
- should be initialized in struct pcmcia_driver, and handle
- (SUSPEND == RESET_PHYSICAL) and (RESUME == CARD_RESET) events
- * 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
