2009-03-13cxgb3: detect mac link faults.Divy Le Ray
The driver currently ignores the local or remote link faults raised at the mac layer. This patch fixes it. Our mac however only advertizes link events, so wait for the phy to stabilize the link, then enable mac link events interrupts. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-13cxgb3: Update Rev3 mac workaroundDivy Le Ray
Update the heurstics workaround unlocking a hung mac: - reduce Tx mac toggling by enabling Tx drain before resetting the mac - Take Tx (lack of) activity in account only - Update the monitoring counter range to 64 bits Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-13cxgb3: disable high freq non-data interruptsDivy Le Ray
Under RX pressure, The HW might generate a high load of interrupts to signal mac fifo or free lists overflow. Disable the interrupts, and poll the relevant status bits to maintain stats. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-03-10forcedeth: version bump to 64Ayaz Abdulla
This patch bumps up the version to 0.64 Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: fix irq clearing and napi spin lock changesAyaz Abdulla
This patch clears the irqstatus register with the exact same events it has read from it. Since the read-write operation is not atomic, a new irqstatus bit could have been set in between these operations and would then be cleared accidentally. Secondly, we now don't need any spin lock protection when scheduling/completing napi poll as the isr will not execute anymore (as we turn off all interrupts now). Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: performance changesAyaz Abdulla
This patch modifies the throughput mode poll settings to reduce the number of interrupts. This is only used by older hardware that need a timer irq in throughput mode. Secondly, this patch increases the default rx ring from 128 to 512. This drastically improves bandwidth utilization for small packets sizes i.e 512 bytes. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: add interrupt moderation logicAyaz Abdulla
This patch adds the logic to moderate the interrupts by changing the mode between throughput and poll. If there has been a large amount of time without any burst of network load, the code will transition to pure throughput mode (where each tx/rx/other will cause an interrupt). If bursts of network load occurs, it will transition to poll based mode to help reduce cpu utilization (it will not interrupt on each packet) while maintaining the optimum network bandwidth utilization. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: remove isr processing loopAyaz Abdulla
This patch is only a subset of changes so that it is easier to see the modifications. This patch removes the isr 'for' loop and shifts all the logic to account for new tab spacing. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: add new optimization modeAyaz Abdulla
A new optimization mode called Dynamic has been added. This will be mode where interrupt moderation logic will dynamically switch between pure throughput mode and poll based (called 'cpu') mode. Also, for newer chipsets, the timer irq is not needed for throughput mode. Secondly, since we are modifying the irqmask to change between modes, msix is not supported. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: napi - handle all processingAyaz Abdulla
The napi poll routine has been modified to handle all interrupt events and process them accordingly. Therefore, the ISR will now only schedule the napi poll and disable all interrupts instead of just disabling rx interrupt. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: add/modify tx done with limitAyaz Abdulla
There are two tx_done routines to handle tx completion processing. Both these functions now take in a limit value and return the amount of tx completions. This will be used by a future patch to determine the total amount of work done. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: remove overheadAyaz Abdulla
This patch removes unnecessary overhead code. Firstly, there is no nead to mask off unwanted interrupts as we will be checking against the irqmask field anyways. Secondly, there has been no value in last few years from detecting error or unknown interrupts. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: save irq events for napi processingAyaz Abdulla
This patch will save the irq events in the driver's context so that the napi routine knows which interrupts have occurred. Subsequent changes will be moving all interrupt processing into the napi poll routine. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: remove msix + napiAyaz Abdulla
This patch removes support for msix running in conjunction with napi. There has been reported issues regarding the behaviour of irqmask and generation of interrupts by the HW when in MSIX mode. When running napi, the driver is constantly turning off/on the irqmask. For the time being, I am going to disable it until I can root cause the issue.

2009-03-10forcedeth: fix missing napi enable/disable callsAyaz Abdulla

2009-03-10forcedeth: fix stats version featureAyaz Abdulla
Newer versions of the stats feature would not encompass all older versions. This would result in only retreiving a subset of all available stats in HW. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-03-10gigaset: return -ENOTTY for unimplemented functionsPaul Bolle
A number of functions in the usb_gigaset module will return -EINVAL if CONFIG_GIGASET_UNDOCREQ is not set. Make these return -ENOTTY as it's more specific and it might make it easier to see (from userspace) why these functions actually fail.

2009-03-05ath9k: Add a debugfs interface for controlling virtual wiphysJouni Malinen
debugfs ath9k/phy#/wiphy can be used to show the current list of virtual wiphys and to add/remove virtual wiphys. Eventually, this interface could be replaced with a cfg80211/nl80211 command that is passed through mac80211. For example: # cat /debug/ath9k/phy0/wiphy primary: phy0 # echo add > /debug/ath9k/phy0/wiphy # cat /debug/ath9k/phy0/wiphy primary: phy0 secondary: phy1 # echo del=phy1 > /debug/ath9k/phy0/wiphy # cat /debug/ath9k/phy0/wiphy primary: phy0 In addition, following commands can be used to test pausing and unpausing of the virtual wiphys: pause=phy1 unpause=phy1 select=phy1 (select pauses and unpauses wiphys automatically based on channel) schedule=500 (set wiphy scheduling interval in msec; 0 = disable; default value: 500) Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

2009-03-05ath9k: Add a simple virtual wiphy schedulerJouni Malinen
This is a very simple scheduler that goes through the wiphys and schedules one at a time every N milliseconds (current default value: 500 ms). This is enough for initial testing, but there are number of areas where a more complex scheduler can improve operations greatly.
