2015-02-27cxgb4: Fix PCI-E Memory window interface for big-endian systemsHariprasad Shenai2-11/+45
When doing reads and writes to adapter memory via the PCI-E Memory Window interface, data gets swizzled on 4-byte boundaries on Big-Endian systems because we need to account for the register read/write interface which incorporates a swizzle onto the Little-Endian PCI-E Bus.

2015-02-26amd-xgbe-phy: PHY KX/KR mode differencesTom Lendacky1-2/+80
The PHY requires different settings for the Decision Feedback Analyzer (DFE) when running in KX mode vs. KR mode. Update the code to change these settings when changing modes in order to provide a more stable link. Additionally, adjust the 10GbE PQ skew default setting to a more sane value.

2015-02-25xen-netback: release pending index before pushing Tx responsesDavid Vrabel1-8/+21
If the pending indexes are released /after/ pushing the Tx response then a stale pending index may be used if a new Tx request is immediately pushed by the frontend. The may cause various WARNINGs or BUGs if the stale pending index is actually still in use. Fix this by releasing the pending index before pushing the Tx response. The full barrier for the pending ring update is not required since the the Tx response push already has a suitable write barrier.

2015-02-24altera_tse: Fixes in NAPI and interrupt handling pathsVlastimil Setka1-23/+22
Incorrect NAPI polling caused WARNING at net/core/dev.c net_rx_action. Some stability issues were also seen at high throughput and system load before this patch. This patch contains several changes in altera_tse_main.c: - tse_rx() is fixed to not process more than `limit` frames - tse_poll() is refactored to match NAPI logic - only received frames are counted for return value - removed bogus condition `(rxcomplete >= budget || txcomplete > 0)` - replace by: if (rxcomplete < budget) -> call __napi_complete and enable irq - altera_isr() - replace spin_lock_irqsave() by spin_lock() - we are in isr - use spinlocks just over irq manipulation, not over __napi_schedule - reset IRQ first, then disable and schedule napi This is a cleaned up resubmission from Vlastimil's recent submission.

2015-02-23team: fix possible null pointer dereference in team_handle_frameJiri Pirko1-3/+1
Currently following race is possible in team: CPU0 CPU1 team_port_del team_upper_dev_unlink priv_flags &= ~IFF_TEAM_PORT team_handle_frame team_port_get_rcu team_port_exists priv_flags & IFF_TEAM_PORT == 0 return NULL (instead of port got from rx_handler_data) netdev_rx_handler_unregister The thing is that the flag is removed before rx_handler is unregistered. If team_handle_frame is called in between, team_port_exists returns 0 and team_port_get_rcu will return NULL. So do not check the flag here. It is guaranteed by netdev_rx_handler_unregister that team_handle_frame will always see valid rx_handler_data pointer.

Reading 64-bits register was not working because we inverted the steps between reading the lower 32-bits of the register and reading the upper 32-bits. Swapping these operations is how the HW guarantees that 64-bits reads are latched correctly. We only have a handful of 64-bits registers for now, mostly MIB counters, so the imapct is low.

The ltpc driver is rather outdated and does not get built on most platforms because it requires the ISA_DMA_API symbol.

Similarly, building for both CONFIG_SA1100_ASSABET and CONFIG_SA1100_PLEB results in a different build error: smsc/smc91x.c: In function 'smc_drv_probe': smsc/smc91x.c:2299:2: error: implicit declaration of function 'neponset_ncr_set' [-Werror=implicit-function-declaration] neponset_ncr_set(NCR_ENET_OSC_EN); ^ smsc/smc91x.c:2299:19: error: 'NCR_ENET_OSC_EN' undeclared (first use in this function) neponset_ncr_set(NCR_ENET_OSC_EN); ^ This is an attempt to fix the call site responsible for both errors, making sure we call the function exactly when the driver is actually trying to run on the assabet/neponset machine.

phy_init_eee uses phy_find_setting(phydev->speed, phydev->duplex) to find a valid entry in the settings array for the given speed and duplex value. For full duplex 1000baseT, this will return the first matching entry, which is the entry for 1000baseKX_Full. If the phy eee does not support 1000baseKX_Full, this entry will not match, causing phy_init_eee to fail for no good reason.

Commit a7854487cd7128a30a7f4f5259de9f67d5efb95f: md: When RAID5 is dirty, force reconstruct-write instead of read-modify-write. Causes an RCW cycle to be forced even when the array is degraded. A degraded array cannot support RCW as that requires reading all data blocks, and one may be missing. Forcing an RCW when it is not possible causes a live-lock and the code spins, repeatedly deciding to do something that cannot succeed. So change the condition to only force RCW on non-degraded arrays.

Of course, the timer interrupts are not wakeup ones, so the handling of them can be deferred until a real wakeup interrupt happens, but at the same time we don't want to mass-expire timers at that point. The solution is to suspend the entire timekeeping when the last CPU is entering an idle state and resume it when the first CPU goes out of idle. That has to be done with care, though, so as to avoid accessing suspended clocksources etc. end we need extra support from idle drivers for that.

2015-02-17watchdog: dw_wdt: Try to get a 30 second watchdog by defaultDoug Anderson1-2/+4
The dw_wdt_set_top() function takes in a value in seconds. In dw_wdt_open() we were calling it with a value that's supposed to represent the maximum value programmed into the "top" register with a comment saying that we were trying to set the watchdog to its maximum value. Instead we ended up setting the watchdog to ~15 seconds. Let's fix this. However, setting things to the "max" gives me an 86 second watchdog in the system I'm looking at. 86 seconds feels a little too long. We'll explicitly choose 30 seconds as a more reasonable value. NOTE: Ideally this driver should be transitioned to be a real watchdog driver. Then we could use "watchdog_init_timeout" and let the timeout be specified in a number of ways (device tree, module parameter, etc). This patch should be considered a bit of a stopgap solution.

2015-02-17watchdog: dw_wdt: pat the watchdog before enabling itDoug Anderson1-7/+19
On some dw_wdt implementations the "top" register may be initted to 0 at bootup. In such a case, each "pat" of the watchdog will reset the timer to 0xffff. That's pretty short. The input clock of the wdt can be any of a wide range of values. On an rk3288 system, I've seen the wdt clock be 24.75 MHz. That means each tick is ~40ns and we'll count to 0xffff in ~2.6ms. Because of the above two facts, it's a really good idea to pat the watchdog after initting the "top" register properly and before enabling the watchdog. If you don't then there's no way we'll get the next heartbeat in time. Jisheng Zhang fixed this problem on some dw_wdt versions by using the TOP_INIT feature. However, the dw_wdt on rk3288 doesn't have TOP_INIT so it's a good idea to also pat the watchdog manually.
