| | * rtlwifi: Add missing DMA buffer unmapping for PCI driversLarry Finger2012-04-111-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In https://bugzilla.kernel.org/show_bug.cgi?id=42976, a system with driver rtl8192se used as an AP suffers from "Out of SW-IOMMU space" errors. These are caused by the DMA buffers used for beacons never being unmapped.

| | * rtlwifi: Preallocate USB read buffers and eliminate kalloc in read routineLarry Finger2012-04-112-19/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current version of rtlwifi for USB operations uses kmalloc to acquire a 32-bit buffer for each read of the device. When _usb_read_sync() is called with the rcu_lock held, the result is a "sleeping function called from invalid context" BUG. This is reported for two cases in https://bugzilla.kernel.org/show_bug.cgi?id=42775. The first case has the lock originating from within rtlwifi and could be fixed by rearranging the locking; however, the second originates from within mac80211. The kmalloc() call is removed from _usb_read_sync() by creating a ring buffer pointer in the private area and allocating the buffer data in the probe routine.

Sounds like a good idea, but that alone doesn't fix anything. The real problem is that the Kconfig has settings related to whether PCI is possible, i.e. config BCMA_HOST_PCI_POSSIBLE bool depends on BCMA && PCI = y default y config BCMA_HOST_PCI bool "Support for BCMA on PCI-host bus" depends on BCMA_HOST_PCI_POSSIBLE ...but what is missing is that BCMA_DRIVER_PCI_HOSTMODE doesn't have any dependencies on the above.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The nl80211 handling code should ensure as much as it can that the interface is in a valid state, it can certainly ensure the interface is running. Not doing so can cause calls through mac80211 into the driver that result in warnings and unspecified behaviour in the driver.

Looking into the patch I noticed a very subtle typo in the ids. The patch has '0x05ac' instead of '0x0a5c'. A snippet of the lsusb -v output also shows this: Bus 002 Device 003: ID 0a5c:21e1 Broadcom Corp. Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 255 Vendor Specific Class bDeviceSubClass 1 bDeviceProtocol 1 bMaxPacketSize0 64 idVendor 0x0a5c Broadcom Corp. idProduct 0x21e1 bcdDevice 1.12 iManufacturer 1 Broadcom Corp iProduct 2 BCM20702A0 iSerial 3 60D819F0338C bNumConfigurations 1 Looking at other Broadcom ids, the fix matches them whereas the original patch matches Apple's ids. Tested on an HP Elitebook 8760w. The btusb binds and the userspace stuff loads correctly.

As a consequence, drivers currently don't know that the device should enable wakeup. However, the device_set_wakeup_enable() API is intended to be called when the wakeup is enabled, not later when needed. Add a new set_wakeup() call to cfg80211 and mac80211 to allow drivers to properly call device_set_wakeup_enable. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

It is fed with pulse events by the radar pulse detector and reports in place whether a pattern was detected. On detection, the result is reported as radar event to the DFS management component in the upper layer. Currently the ETSI DFS domain is supported with detector lines for the patterns defined by EN-301-893 v1.5.1. Support for FCC and JP will be added gradually. To include the pattern detector, ath9k must be built with support for DFS certified config flag set (CONFIG_ATH9K_DFS_CERTIFIED).

This is already problematic for off-channel uses since if we go off channel while the BE queue is full and then try to send an off-channel frame the frame will never go out. This will become worse when we support multi-channel since then a queue on one channel might be full, but we have to stop the software queue for all channels. That is obviously not desirable. To address this problem allow drivers to register more hardware queues, and allow them to map them to virtual interfaces. When they stop a hardware queue the corresponding AC software queues on the correct interfaces will be stopped as well. Additionally, there's an off-channel queue to solve that problem and a per-interface after-DTIM beacon queue. This allows drivers to manage software queues closer to how the hardware works. Currently, there's a limit of 16 hardware queues. This may or may not be sufficient, we can adjust it as needed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

One possible option would be to have the driver tell mac80211 about monitor mode queues etc., but that would duplicate the API since we already need to have queue assignments handled per virtual interface. So in order to solve this, have a virtual monitor interface that is added whenever all active vifs are monitors. We could also use the state of one of the monitor interfaces, but managing that would be complicated, so allocate separate state.
