- Shared driver code for IEEE 802.11b wireless cards based on
- Intersil Prism2/2.5/3 chipset. This driver supports so called
- Host AP mode that allows the card to act as an IEEE 802.11
- access point.
-
- See <http://hostap.epitest.fi/> for more information about the
- Host AP driver configuration and tools. This site includes
- information and tools (hostapd and wpa_supplicant) for WPA/WPA2
- support.
-
- This option includes the base Host AP driver code that is shared by
- different hardware models. You will also need to enable support for
- PLX/PCI/CS version of the driver to actually use the driver.
-
- The driver can be compiled as a module and it will be called

- support cards that don't have firmware in flash, such as D-Link
- DWL-520 rev E and D-Link DWL-650 rev P.

- * FIX:
- * - there is currently no way of associating TX packets to correct wds device
- * when TX Exc/OK event occurs, so all tx_packets and some
- * tx_errors/tx_dropped are added to the main netdevice; using sw_support
- * field in txdesc might be used to fix this (using Alloc event to increment
- * tx_packets would need some further info in txfid table)
- *
- * Buffer Access Path (BAP) usage:
- * Prism2 cards have two separate BAPs for accessing the card memory. These
- * should allow concurrent access to two different frames and the driver
- * previously used BAP0 for sending data and BAP1 for receiving data.
- * However, there seems to be number of issues with concurrent access and at
- * least one know hardware bug in using BAP0 and BAP1 concurrently with PCI
- * Prism2.5. Therefore, the driver now only uses BAP0 for moving data between
- * host and card memories. BAP0 accesses are protected with local->baplock
- * (spin_lock_bh) to prevent concurrent use.

-/* Locking and synchronization:
- *
- * The basic principle is that everything is serialized through a
- * single spinlock, priv->lock. The lock is used in user, bh and irq
- * context, so when taken outside hardirq context it should always be
- * taken with interrupts disabled. The lock protects both the
- * hardware and the struct orinoco_private.
- *
- * Another flag, priv->hw_unavailable indicates that the hardware is
- * unavailable for an extended period of time (e.g. suspended, or in
- * the middle of a hard reset). This flag is protected by the
- * spinlock. All code which touches the hardware should check the
- * flag after taking the lock, and if it is set, give up on whatever
- * they are doing and drop the lock again. The orinoco_lock()
- * function handles this (it unlocks and returns -EBUSY if
- * hw_unavailable is non-zero).

- *
- * Here's the general details on how the PLX9052 adapter works:
- *
- * - Two PCI I/O address spaces, one 0x80 long which contains the
- * PLX9052 registers, and one that's 0x40 long mapped to the PCMCIA
- * slot I/O address space.
- *
- * - One PCI memory address space, mapped to the PCMCIA attribute space
- * (containing the CIS).
- *
- * Using the later, you can read through the CIS data to make sure the
- * card is compatible with the driver. Keep in mind that the PCMCIA
- * spec specifies the CIS as the lower 8 bits of each word read from
- * the CIS, so to read the bytes of the CIS, read every other byte
- * (0,2,4,...). Passing that test, you need to enable the I/O address
- * space on the PCMCIA card via the PCMCIA COR register. This is the
- * first byte following the CIS. In my case (which may not have any
- * relation to what's on the PRISM2 cards), COR was at offset 0x800
- * within the PCI memory space. Write 0x41 to the COR register to
- * enable I/O mode and to select level triggered interrupts. To
- * confirm you actually succeeded, read the COR register back and make
- * sure it actually got set to 0x41, in case you have an unexpected
- * card inserted.
- *
- * Following that, you can treat the second PCI I/O address space (the
- * one that's not 0x80 in length) as the PCMCIA I/O space.
- *
- * Note that in the Eumitcom's source for their drivers, they register
- * the interrupt as edge triggered when registering it with the
- * Windows kernel. I don't recall how to register edge triggered on
- * Linux (if it can be done at all). But in some experimentation, I
- * don't see much operational difference between using either
- * interrupt mode. Don't mess with the interrupt mode in the COR
- * register though, as the PLX9052 wants level triggers with the way
- * the serial EEPROM configures it on the WL11000.
- *
- * There's some other little quirks related to timing that I bumped
- * into, but I don't recall right now. Also, there's two variants of
- * the WL11000 I've seen, revision A1 and T2. These seem to differ
- * slightly in the timings configured in the wait-state generator in
- * the PLX9052. There have also been some comments from Eumitcom that
- * cards shouldn't be hot swapped, apparently due to risk of cooking
- * the PLX9052. I'm unsure why they believe this, as I can't see
- * anything in the design that would really cause a problem, except
- * for crashing drivers not written to expect it. And having developed
- * drivers for the WL11000, I'd say it's quite tricky to write code
- * that will successfully deal with a hot unplug. Very odd things
- * happen on the I/O side of things. But anyway, be warned. Despite
- * that, I've hot-swapped a number of times during debugging and
- * driver development for various reasons (stuck WAIT# line after the
- * radio card's firmware locks up).
