* stmmac: fix missing MODULE_LICENSE in stmmac_platformJoachim Eastwood2015-08-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 50649ab14982 ("stmmac: drop driver from stmmac platform code") was a bit overzealous in removing code and dropped the MODULE_* macro's that are still needed since stmmac_platform can be a module. Fix this by putting the macro's remvoed in 50649ab14982 back. This fixes the following errors when used as a module: stmmac_platform: module license 'unspecified' taints kernel. Disabling lock debugging due to kernel taint stmmac_platform: Unknown symbol devm_kmalloc (err 0) stmmac_platform: Unknown symbol stmmac_suspend (err 0) stmmac_platform: Unknown symbol platform_get_irq_byname (err 0) stmmac_platform: Unknown symbol stmmac_dvr_remove (err 0) stmmac_platform: Unknown symbol platform_get_resource (err 0) stmmac_platform: Unknown symbol of_get_phy_mode (err 0) stmmac_platform: Unknown symbol of_property_read_u32_array (err 0) stmmac_platform: Unknown symbol of_alias_get_id (err 0) stmmac_platform: Unknown symbol stmmac_resume (err 0) stmmac_platform: Unknown symbol stmmac_dvr_probe (err 0) Fixes: 50649ab14982 ("stmmac: drop driver from stmmac platform code") Reported-by: Igor Gnatenko <i.gnatenko.brain@gmail.com> Signed-off-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: David S.

* gianfar: Enable device wakeup when appropriateClaudiu Manoil2015-08-013-13/+3
| | | | | | | | | | | | | | | | | | The wol_en flag is 0 by default anyway, and we have the following inconsistency: a MAGIC packet wol capable eth interface is registered as a wake-up source but unable to wake-up the system as wol_en is 0 (wake-on flag set to 'd'). Calling set_wakeup_enable() at netdev open is just redundant because wol_en is 0 by default. Let only ethtool call set_wakeup_enable() for now. The bflock is obviously obsoleted, its utility has been corroded over time. The bitfield flags used today in gianfar are accessed only on the init/ config path, with no real possibility of concurrency - nothing that would justify smth. like bflock.

* gianfar: Fix suspend/resume for wol magic packetClaudiu Manoil2015-08-011-68/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we disable NAPI in the first place we can mask the device's interrupts (and halt it) without fearing that imask may be concurrently accessed from interrupt context, so there's no need to do local_irq_save() around gfar_halt_nodisable(). lock_rx_qs()/unlock_tx_qs() are just obsoleted and potentially buggy routines. The txlock is currently used in the driver only to manage TX congestion, it has nothing to do with halting the device. With these changes, the TX processing is stopped before gfar_halt(). Compact gfar_halt() is used instead of gfar_halt_nodisable(), as it disables Rx/TX DMA h/w blocks and the Rx/TX h/w queues. gfar_start() re-enables all these blocks on resume. Enabling the magic-packet mode remains the same, note that the RX block is re-enabled just before entering sleep mode. Add IRQF_NO_SUSPEND flag for the error interrupt line, to signal that the interrupt line must remain active during sleep in order to wake the system by magic packet (MAG) reception interrupt. (On some systems the MAG interrupt did trigger w/o this flag as well, but on others it didn't.) Without these fixes, when suspended during fair Tx traffic the interface occasionally failed to be woken up by magic packet.

| | | | | | | | | | | | | | | | | | | | | With earlier configured value sufficient number of CQEs are not being reserved for transmitted packets. Hence under heavy incoming traffic load, receive notifications will take away most of the CQ thus transmit notifications will be lost resulting in tx skbs not being freed. Finally SQ will be full and it will be stopped, watchdog timer will kick in. After this fix receive notifications will not take morethan half of CQ reserving the rest for transmit notifications. Also changed CQ & SQ sizes from 16k to 4k. This is also due to the receive notifications taking first half of CQ under heavy load and time taken by NAPI to clear transmit notifications will increase with higher queue sizes. Again results in SQ being stopped. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: Aleksey Makarov <aleksey.makarov@caviumnetworks.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | When a switch is attached to the mdio bus, the mdio bus can be used while the interface is not open. If the IPG clock is not enabled, MDIO reads/writes will simply time out. Add support for runtime PM to control this clock. Enable/disable this clock using runtime PM, with open()/close() and mdio read()/write() function triggering runtime PM operations. Since PM is optional, the IPG clock is enabled at probe and is no longer modified by fec_enet_clk_enable(), thus if PM is not enabled in the kernel, it is guaranteed the clock is running when MDIO operations are performed.

| | | | | | | | | | | | | | | | | | | | | | When a port is not attached, the FW requires a longer than usual time to execute the SENSE_PORT command. In the command flow, the wait_for_completion_timeout call used in mlx4_cmd_wait puts the kernel thread into the uninterruptible state during this time. This, in turn, due to the computation method, causes the CPU load average to increase. Fix this by using wait_for_completion_interruptible_timeout() for the SENSE_PORT command, which puts the thread in the interruptible state. In this state, the thread does not contribute to the CPU load average. Treat the interrupted case as if the SENSE_PORT command returned port_type = NONE.

| * ravb: fix ring memory allocationSergei Shtylyov2015-07-221-25/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver is written as if it can adapt to a low memory situation allocating less RX skbs and TX aligned buffers than the respective RX/TX ring sizes. In reality though the driver would malfunction in this case. Stop being overly smart and just fail in such situation -- this is achieved by moving the memory allocation from ravb_ring_format() to ravb_ring_init(). We leave dma_map_single() calls in place but make their failure non-fatal by marking the corresponding RX descriptors with zero data size which should prevent DMA to an invalid addresses.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the byte order copying in the MAO (Mac Override Section) section from the PNVM, as the byte swapping is not required anymore in the 8000 family. Due to the byte swapping, the driver was reporting an incorrect MAC adddress.

As a consequence, the driver will crash if it ever tries to delete this time event in case initialization was unsuccessful. Avoid this by using the time event's vif pointer to indicate validity. The vif pointer is != NULL whenever the id is != TE_MAX, except for this special error case where the vif pointer will have the correct property (as the whole memory is cleared on allocation) whereas the id is 0, causing a crash in trying to delete the time event from the list.
