2013-04-22rt2x00: provide separate information about TXWI & RXWI sizesStanislaw Gruszka
On new 2800 hardware sizes of TXWI & RXIW can be different than TXD & RXD sizes, so we need to difference between them. Let's define winfo_size as size of in buffer descriptor (TXWI & RXWI), and desc_size of as size of additional descriptor - in separate DMA coherent buffer for PCI hardware (TXD & RXD) and yet another in buffer descriptor for USB hardware (TXINFO & RXINFO). Change is rt2x00 wild, but should affect only 2800 driver. Patch also fix beaconing for 5592usb AP mode.

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.

2013-03-18rt2x00: Fix tx status reporting for reordered frames in rt2800pciHelmut Schaa
rt2800 hardware sometimes reorders tx frames when transmitting to multiple BA enabled STAs concurrently. For example a tx queue [ STA1 | STA2 | STA1 | STA2 ] can result in the tx status reports [ STA1 | STA1 | STA2 | STA2 ] when the hw decides to put the frames for STA1 in one AMPDU. To mitigate this effect associate the currently processed tx status to the first frame in the tx queue with a matching wcid. This patch fixes several problems related to incorrect tx status reporting. Furthermore the tx rate selection is much more stable when communicating with multiple STAs.

2012-03-12rt2x00: Fix beacon skew in rt2800pciHelmut Schaa
rt2800pci is suffering from beacon skew in AP mode. Some powersaving clients (like VOIP phones) are getting into trouble after some time when the beacon skew is getting too big. The ralink legacy drivers contain a function that indicates that the beacon timer is off by 1us per tbtt. And this function works around that by reducing the beacon interval for every 64th beacon transmission by 64us (the smallest possible value). Do the same in rt2800pci. This allows proper powersaving when rt2800pci is used in AP mode. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2012-01-13rt2800pci: fix spurious interrupts generationStanislaw Gruszka
Same devices can generate interrupt without properly setting bit in INT_SOURCE_CSR register (spurious interrupt), what will cause IRQ line will be disabled by interrupts controller driver. We discovered that clearing INT_MASK_CSR stops such behaviour. We previously first read that register, and then clear all know interrupt sources bits and do not touch reserved bits. After this patch, we write to all register content (I believe writing to reserved bits on that register will not cause any problems, I tested that on my rt2800pci device). This fix very bad performance problem, practically making device unusable (since worked without interrupts), reported in: https://bugzilla.redhat.com/show_bug.cgi?id=658451 We previously tried to workaround that issue in commit 4ba7d9997869d25bd223dea7536fc1ce9fab3b3b "rt2800pci: handle spurious interrupts", but it was reverted in commit 82e5fc2a34fa9ffea38f00c4066b7e600a0ca5e6 as thing, that will prevent to detect real spurious interrupts.

2011-09-14rt2x00: Make use of sta_add/remove callbacks in rt2800Helmut Schaa
This allows us to assign a WCID to each STA even for STAs without crypto key. To achieve this search for an unused WCID in the HW WCID table and assign it to the according STA. When configuring a pairwise key for this STA we don't need to write the MAC address and BSSIDX anymore but just update the crypto related fields in the WCID_ATTR table. This has two advantages: 1) Setting a new key for an already available STA (PTK rekeying) is slightly less expensive and should improve performance in situations where a lot of rekeying happens (e.g. a huge number of stations and/or a small rekeying interval) 2) The TXWI now gets a WCID assigned for unencrypted frames which will be reflected in the corresponding tx status report. This should make tx status reports in unencrypted AP mode more reliable as we can distinguish between multiple key-less STAs.

2011-08-09rt2x00: Fix PCI interrupt processing race on SMP systemsHelmut Schaa
When toggle_irq is called for PCI devices to disable device interrupts it used tasklet_disable to wait for a possibly running tasklet to finish. However, on SMP systems the tasklet might still be scheduled on another CPU. Instead, use tasklet_kill to ensure that all scheduled tasklets are finished before returning from toggle_irq. Furthermore, it was possible that a tasklet reenabled its interrupt even though interrupts have been disabled already. Fix this by checking the DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts during tasklet processing. While at it also enable/kill the TBTT and PRETBTT tasklets in the toggle_irq callback and only use tasklet_kill in stop_queue to wait for a currently scheduled beacon update before returning.

2011-04-19rt2x00: Optimize register access in rt2800pciHelmut Schaa
All register reads/writes in rt2800pci were previously done with rt2800_register_read/rt2800_register_write. These however indirectly call rt2x00pci_register_read/rt2x00pci_register_write which adds an additional overhead of at least one call and several move instructions to each register access. Replacing the calls to rt2800_register_read/rt2800_register_write with direct calls to rt2x00pci_register_read/rt2x00pci_register_write gets rid of quite a number of instructions in the drivers hotpaths (IRQ handling and txdone handling). For consistency replace all references to rt2800_register_read/write with the rt2x00pci_register_read/write variants.

2011-04-19rt2x00: Allow dynamic addition of PCI/USB IDs.Gertjan van Wingerde
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/<driver-name>/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.

2011-04-19rt2x00: Always inline rt2x00pci_enable_interruptHelmut Schaa
This allows the compiler to perform the necessary bitfield calculations during compile time instead of run time and thus reduces the number of instructions to run during each tasklet invocation. This should improve performance in the RX hotpath. This comes at the cost of a slight increase in the module size (for example rt2800pci): Before: text data bss dec hex filename 14133 832 4 14969 3a79 drivers/net/wireless/rt2x00/rt2800pci.ko After: text data bss dec hex filename 14149 832 4 14985 3a89 drivers/net/wireless/rt2x00/rt2800pci.ko Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2011-04-19rt2x00: Decrease association time for USB devicesIvo van Doorn
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).
