rt2x00: Fix FSF address in file headers

2013-12-11T15:56:19Z

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL so that we do not have to keep updating the header comments anytime the address changes.

rt2x00: rt2x00pci: fix build error on Ralink RT3x5x SoCs

2013-04-03T18:50:06Z

The rt2800pci driver supports the built-in wireless MAC of the Ralink RT3x5x SoCs. However building the driver for these SoCs leads to the following error: LD init/built-in.o drivers/built-in.o: In function `rt2800pci_rxdone_tasklet': <...>/drivers/net/wireless/rt2x00/rt2800pci.c:1012: undefined reference to `rt2x00pci_rxdone' drivers/built-in.o:(.rodata+0x4780): undefined reference to `rt2x00pci_initialize' drivers/built-in.o:(.rodata+0x4784): undefined reference to `rt2x00pci_uninitialize' drivers/built-in.o:(.rodata+0x47bc): undefined reference to `rt2x00pci_flush_queue' drivers/built-in.o:(.rodata+0x4818): undefined reference to `rt2x00pci_regbusy_read' make[5]: *** [vmlinux] Error 1 The missing functions are provided by the rt2x00pci module. This module is only selected by the rt2800pci driver if PCI support is enabled in the kernel, because some parts of the rt2x00pci code depends on PCI support. PCI support is not available on the RT3x5x SoCs because those have no PCI host controller at all. Move the non PCI specific code from rt2x00pci into a separate module. This makes it possible to use that code even if PCI support is disabled. The affected functions are used by all of the rt2x00 PCI drivers so select the new module for those drivers.

rt2x00: Allow dynamic addition of PCI/USB IDs.

2011-04-19T19:39:45Z

Both USB and PCI drivers allow a system administrator to dynamically add USB/PCI IDs to the device table that a driver supports via the /sys/bus/{usb,pci,pci_express}/drivers//new_id files. However, for the rt2x00 drivers using this method currently crashes the system with a NULL pointer failure. This is due to the set-up of rt2x00 where the probe functions require a rt2x00_ops structure in the driver_info field of the probed device. As this field is empty for the dynamically added devices this fails for these devices. Fix this by introducing driver-specific probe wrappers that do nothing but calling the bus-specific probe functions with the rt2x00_ops structure as an argument, rather than depending on the driver_info field.

rt2x00: Decrease association time for USB devices

2011-04-19T19:39:37Z

When powersaving is enabled, assocaition times are very high (for WPA2 networks, the time can easily be around the 3 seconds). This is caused, because the flushing of the queues takes too much time. Without the flushing callback mac80211 assumes a timeout of 100ms while scanning. Limit all flush waiting loops to the same maximum. We can apply this maximum by passing the drop status to the driver, which makes sure the driver performs extra actions during the waiting for the queue to become empty. After these changes, association times fall within the healthy range of ~0.6 seconds with powersaving enabled. The difference between association time between powersaving enabled and disabled is now only ~0.1 second (which can also be due to the measuring method).

rt2x00: Limit rt2x00pci rxdone processing to 16 entries at once

2011-04-04T20:20:01Z

Instead of receiving an unlimited number of frames, stop after 16 entries and reschedule the rxdone tasklet. This allows other tasklets to be run inbetween. Signed-off-by: Helmut Schaa Acked-by: Gertjan van Wingerde Signed-off-by: Ivo van Doorn Signed-off-by: John W. Linville

rt2x00: Fix firmware loading regression on x86_64.

2010-12-13T20:23:37Z

Commit 6175ddf06b6172046a329e3abfd9c901a43efd2e changes the way memcpy_toio() works for x86_64, causing firmware loading to fail for some Ralink WLAN devices with the rt2800pci driver since linux 2.6.34. This causes the log message: "phy0 -> rt2800pci_load_firmware: Error - PBF system register not ready.". Fix this by using __iowrite32_copy instead of memcpy_toio().

rt2x00: Move common txdone handling to rt2x00lib_txdone.

2010-06-30T19:00:50Z

Now that the write_tx_data functions are merged, also merge the relevant parts of the txdone handling into common code, rather than {usb,pci} specific code. Signed-off-by: Gertjan van Wingerde Signed-off-by: Ivo van Doorn Signed-off-by: John W. Linville

rt2x00: Merge PCI and USB versions of write_tx_data into single function.

2010-06-30T19:00:50Z

Now that rt2x00pci_write_tx_data and rt2x00usb_write_tx_data are similar we can merge them in a single function in rt2x00queue.c. Signed-off-by: Gertjan van Wingerde Signed-off-by: Ivo van Doorn Signed-off-by: John W. Linville

rt2x00: Properly reserve room for descriptors in skbs.
