We almost never need to the Host Command that was sent while handling its response, but when we do need it, we see that the command has been modified. This mystery has been elucidated. The FH (our DMA engine) writes its meta data on the buffer in the DRAM. Of course it copies the buffer to the NIC first. This was known to happen for Tx command, but as a matter of fact, it happens to all TFD brought by the FH which doesn't care much about what it brings from DRAM to internal SRAM. So copy the Host Command to yet another buffer so that we can properly pass the buffer that was sent originally to the fw. Do that only if it was request by the user since very few flows need to get the HCMD sent in the response handler.

The problem is fixed by using request_firmware_nowait() and delaying the start of mac80211 until the firmware is loaded. To prevent the possibility of the driver being unloaded while the firmware loading callback is still active, a completion queue entry is used.

It should make configuring kernel easier in case of not enabled PHY type support. Secondly, always print info about PHY.

Most conversions are straight-forward. Ones worth mentioning are, * drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always use mod_delayed_work() and cancel loop in edac_mc_reset_delay_period() is dropped. * drivers/platform/x86/thinkpad_acpi.c: No need to remember whether watchdog is active or not. @fan_watchdog_active and related code dropped. * drivers/power/charger-manager.c: Seemingly a lot of delayed_work_pending() abuse going on here. [delayed_]work_pending() are unsynchronized and racy when used like this. I converted one instance in fullbatt_handler(). Please conver the rest so that it invokes workqueue APIs for the intended target state rather than trying to game work item pending state transitions. e.g. if timer should be modified - call mod_delayed_work(), canceled - call cancel_delayed_work[_sync](). * drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling() simplified. Note that round_jiffies() calls in this function are meaningless. round_jiffies() work on absolute jiffies not delta delay used by delayed_work. v2: Tomi pointed out that __cancel_delayed_work() users can't be safely converted to mod_delayed_work(). They could be calling it from irq context and if that happens while delayed_work_timer_fn() is running, it could deadlock. __cancel_delayed_work() users are dropped.

There are two ways to provide the link tty_struct => tty_port. Either by calling tty_port_install from tty->ops->install or tty_port_register_device called instead of tty_register_device when the device is being set up after connected. In this patch we modify most of the drivers to do the latter. When the drivers use tty_register_device and we have tty_port already, we switch to tty_port_register_device. So we have the tty_struct => tty_port link for free for those.

The idea behind the function was to provide some variation in the starting offset for the page in order to reduce hot-spots in the cache. However it doesn't appear to provide any significant benefit in the testing I have done. It has however been a source of several bugs, and it blocks us from being able to use 2K fragments on larger page sizes. So the decision I made was to remove it.

Instead we will simply walk through the page using up to 3K per receive, and if we receive less than we only move the offset by that amount. We will free the page when there is no longer any space left that we can use instead of checking the page count to see if we can cycle back to the start. The main motivation behind this is to avoid the unnecessary truesize cost for using a half page when most packets are 2K or smaller. With this new approach the largest possible truesize for a page fragment will be 3K when PAGE_SIZE is larger than 4K.

There are multiple advantages to this. First it allows us to reuse the page much more in the case of pages larger than 4K. It also allows us to avoid some expensive atomic operations in the form of get_page/put_page. In perf I have seen CPU utilization for put_page drop from 3.5% to 1.8% as a result of this patch when doing small packet routing, and packet rates increased by about 3%.

The main motivation behind this change is to help reduce the overhead in the non-RSC case. Previously the non-RSC path code would always be checking for append count even if RSC had been disabled. Now this code is completely skipped in a single conditional check instead of having to make two separate checks.

Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away. This patch doesn't make any functional difference.

Mark them deprecated and convert all users to system[_freezable]_wq. If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant, so there's no reason to use system_nrt[_freezable]_wq. Please use system[_freezable]_wq instead. This patch doesn't make any functional difference. Signed-off-by: Tejun Heo Acked-By: Lai Jiangshan Cc: Jens Axboe Cc: David Airlie Cc: Jiri Kosina Cc: "David S.

IPv4 (and TCP or UDP over IPv4) are currently supported; this patch adds transmit hashing for IPv6 (and TCP or UDP over IPv6), bringing IPv6 up to par with IPv4 support in the bonding driver. In addition, bounds checking has been added to all transmit hashing functions. The algorithm chosen (xor'ing the bottom three quads of the source and destination addresses together, then xor'ing each byte of that result into the bottom byte, finally xor'ing with the last bytes of the MAC addresses) was selected after testing almost 400,000 unique IPv6 addresses harvested from server logs. This algorithm had the most even distribution for both big- and little-endian architectures while still using few instructions. Its behavior also attempts to closely match that of the IPv4 algorithm. The IPv6 flow label was intentionally not included in the hash as it appears to be unset in the vast majority of IPv6 traffic sampled, and the current algorithm not using the flow label already offers a very even distribution. Fragmented IPv6 packets are handled the same way as fragmented IPv4 packets, ie, they are not balanced based on layer 4 information. Additionally, IPv6 packets with intermediate headers are not balanced based on layer 4 information. In practice these intermediate headers are not common and this should not cause any problems, and the alternative (a packet-parsing loop and look-up table) seemed slow and complicated for little gain.

In the same fashion as similar translation functions in linux/mii.h, move these functions from the PHYLIB core to the linux/mdio.h header file so the code will not have to be duplicated in each driver needing MMD-to-ethtool (and vice-versa) translations. The function and some variable names have been renamed to be more descriptive. Not tested on the only hardware that currently calls the related functions, stmmac, because I don't have access to any. Has been compile tested and the translations have been tested on a locally modified version of e1000e. Signed-off-by: Bruce Allan Cc: Giuseppe Cavallaro Signed-off-by: David S.

This complicates buffer management and tends to result in cache read misses when we recycle such buffers (particularly if DMA-coherent memory requires caches to be disabled). Replace the free list with a simple mapping by descriptor index. We know that there is always a payload descriptor between any two descriptors with TSO header buffers, so we can allocate only one such buffer for each two descriptors. While we're at it, use a standard error code for allocation failure, not -1.

Since efx_start_all() is a no-op when the NIC is disabled, this is probably harmless in the case of efx_change_mtu(), but efx_realloc_channels() also reenables interrupts which could be a bad thing to do. Change efx_start_all() and efx_start_interrupts() to assert that the NIC is not disabled, but make efx_stop_interrupts() do nothing if the NIC is disabled (since it is already stopped), consistent with efx_stop_all(). Update comments for efx_start_all() and efx_stop_all() to describe their purpose and preconditions more accurately. Add a common function to check and log if the NIC is disabled, and use it in efx_net_open(), efx_change_mtu() and efx_realloc_channels().

In particular, changes to efx_nic::state are documented as serialised by the RTNL lock, but they aren't. 1. We check whether a reset was requested during probe (suggesting broken hardware) before we allow requested resets to be scheduled. This leaves a window where a requested reset would be deferred indefinitely. 2. Although we cancel the reset work item during device removal, there are still later operations that can cause it to be scheduled again. We need to check the state before scheduling it. 3. Since the state can change between scheduling and running of the work item, we still need to check it there, and we need to do so *after* acquiring the RTNL lock which serialises state changes. 4. We must cancel the reset work item during device removal, if the state could ever have been READY. This wasn't done in some of the failure paths from efx_pci_probe().

Present patch ensures that if a NIC is already locked-up, the driver will recover from it when initializing the device. It does the equivalent of the following recovery sequence: - write NVREG_TX_PAUSEFRAME_ENABLE_V1 to eth1's register NvRegTxPauseFrame - write NVREG_XMITCTL_START to eth1's register NvRegTransmitterControl - write 0 to eth1's register NvRegTransmitterControl (this is at the heart of the "unbricking" sequence mentioned in patch "net-forcedeth: fix TX timeout caused by TX pause on down link") Tested: - hardware is MCP55 device id 10de:0373 (rev a3), dual-port - reboot a kernel without any of patches mentioned - freeze the NIC (details on description for commit "net-forcedeth: fix TX timeout caused by TX pause on down link") - wait 5mn until ping hangs & TX timeout in dmesg - reboot on kernel with present patch - host is immediatly operational, no TX timeout Signed-off-by: David Decotigny Signed-off-by: David S.

Fixing the same. Change log of the original fix: Currently RSS rings are not created in a multi-channel config. RSS rings can be created on one (out of four) interfaces per port in a multi-channel config. Doing this insulates the driver from a FW bug wherin multi-channel config is wrongly reported even when not enabled. This also helps performance in a multi-channel config, as one interface per port gets RSS rings. Signed-off-by: Sathya Perla Signed-off-by: David S.

The of_device_id[] array allows for per-entry private data, so we use that to store details about each type of node that the driver supports. This removes the need to check the 'compatible' property inside the probe function. The driver supports four types on MDIO devices: 1) Gianfar MDIO nodes that only map the MII registers 2) Gianfar MDIO nodes that map the full MDIO register set 3) eTSEC2 MDIO nodes (which map the full MDIO register set) 4) QE MDIO nodes (which map only the MII registers) Gianfar, eTSEC2, and QE have different mappings for the TBIPA register, which is needed to initialize the TBI PHY. In addition, the QE needs a special hack because of the way the device tree is ordered. All of this information is encapsulated in the fsl_pq_mdio_data structure, so when an MDIO node is probed, per-device data and functions are used to determine how to initialize the device.

The original hardware only supported 10M and 100M. Later versions added 1G support. Here we update the driver to make use of this. Also minor logic clean-ups for testing PHY registration error codes and TX complete high water marks. Signed-off-by: David Daney Acked-by: David S.

Use case here is, if BSP considers using mdio-gpio bus along with stmmac driver by passing mdio_bus_data as NULL in platform data. Call to stmmac_mdio_register with mdio_bus_data as NULL returns 0, which is a considered sucessfull call form stmmac. Then again when we unload the driver we just call stmmac_mdio_unregister, this is were the actual problem is stmmac-mdio code dont really know at this instance of calling that stmmac_mdio_register was actually successful. So Adding a check in stmmac_mdio_unregister is always safe. Without this patch stmmac driver calls stmmac_mdio_register from stmmac_release which Segfaults as mii bus was never registered at the first point. Originally the this bug was found when unloading an stmmac driver instance which uses mdio-gpio for smi access. Signed-off-by: Srinivas Kandagatla Signed-off-by: David S.

This patch removes bus_id from mdio platform data, The reason to remove bus_id is, stmmac mdio bus_id is always same as stmmac bus-id, so there is no point in passing this in different variable. Also stmmac ethernet driver connects to phy with bus_id passed its platform data. So, having single bus-id is much simpler. Signed-off-by: Srinivas Kandagatla Signed-off-by: David S.

With a fast network round-trip and a little scheduling latency of the ARP monitor work, a limit of n*delta_in_ticks may effectively mean (n-1)*delta_in_ticks. This is fatal in case of n==1 (the link will stay down forever) and makes the behaviour non-deterministic in all the other cases. Add a delta_in_ticks/2 time slack to all the time limits.

Suppose there are 4 ath9k-htc usb dongles working, kernel has to consume about 4*50KBytes RAM to cache firmware for all dongles. After applying the patch, kernel only caches one single firmware image in RAM for all ath9k-htc devices just during system suspend/resume cycle. When system is ready for loading firmware, ath9k-htc can request the loading from usersapce. During system resume, ath9k-htc still can load the firmware which was cached in kernel memory before system suspend. Cc: ath9k-devel@lists.ath9k.org Cc: "Luis R.

A frame would be completed with ATH9K_TXERR_FILT status only when the corresponding filter bit for the destination station is already set. Currently, un-acknowledged packets are added to the pending queue and retried, but the "clear_dest_mask" bit in the descriptor is set only when the TX status has been ATH9K_TXERR_FILT. This results in packet loss and the log shows: wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746071 wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746076 wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746377 ... ...

Hence separate entries are created in "adapter->bss_prio_tbl" for these interfaces and station packet is dequeued only if there is not packet in queue for AP. It is observed that ping for station interface doesn't work if heavy traffic is running on AP. The problem is fixed by having same priority for both the interfaces.

"bss_prio_tbl[j].bss_prio_cur" is supposed to point to next interface every time the routine for dequeuing the packet is called. This ensures that each interface gets fair chance. Currently we have AP and station interfaces with priority '0'. Therefore "adapter->bss_prio_tbl[0].bss_prio_cur" should alternately point to AP and station nodes. Since "bss_prio_cur" is not correctly updated, for each packet picked for AP, two packets are picked for station interface. This patch fixes the problem by correctly updating "bss_prio_cur".

This means that device init can complete with commands pending, and the if_sdio driver will sometimes power down the device (after init) with this command still pending. This was causing an occasional spurious command timeout after init, leading to a device reset. Fix this by making CMD_MAC_CONTROL synchronous when called from the lbs_setup_firmware() path.

This patch adds e-scan support (currently i-scan is in use). E-scan is a more powerful and memory efficient method for scanning. E-scan will be the default scan method and eventually, i-scan support will be removed. The scan methods do not make any difference to the end-user.

In many of these cases, there is no need to do cause such a flap, as the associated flows should not actually affect the link. This patch adds the 'Link Flap Avoidance' mechanism, which allows the driver to better determine if a given flow requires a link change, and thus minimize the number of link flaps caused by the driver.
