2012-02-07e1000e: cleanup - check return values consistentlyBruce Allan2-5/+5
The majority of the e1000e code checks most function return values using a test like 'if (ret_val)' or 'if (!ret_val)' but there are a few instances of 'if (ret_val == 0)'. This patch converts the latter to the former for consistency. Signed-off-by: Bruce Allan <[email protected]> Tested-by: Aaron Brown <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>

2012-01-26e1000e: split lib.c into three more-appropriate filesBruce Allan4-995/+1051
The generic lib.c file contains code relative to the various MACs, NVM and Manageability supported by the driver. This patch splits the file into three which are specific to those areas similar to how the PHY-specific code is in phy.c and code specific to the 80003es2lan, 8257x, and ichX MAC families are in their own files. The generic code that is applicable to all MAC/PHY parts supported by the driver remains in netdev.c, param.c and ethtool.c files. No change in functionality, just moving code around for ease of maintenance, with some whitespace and other checkpatch cleanups.

Use the default hardware values for TIPG except for 80003es2lan(*). The code that is removed in this patch is either unnecessarily writing the TIPG register with the hardware default values for some devices (82571/2/3/4) or writing the wrong value for others (ICH/PCH LOMs). The only change in functionality is setting the correct default TIPG for the latter devices. (*) The correct value for 80003es2lan is already set properly in e1000_init_hw_80003es2lan() and e1000_cfg_kmrn_{10_100|1000}_80003es2lan(), and the unused flag FLAG_TIPG_MEDIUM_FOR_80003ESLAN is removed.

2011-12-05e1000e: hitting BUG_ON() from napi_enableBruce Allan1-2/+2
Based on a patch from Mike McElroy created against the out-of-tree e1000e driver: Hitting the BUG_ON in napi_enable(). Code inspection shows that this can only be triggered by calling napi_enable() twice without an intervening napi_disable(). I saw the following sequence of events in the stack trace: 1) We simulated a cable pull using an Extreme switch. 2) e1000_tx_timeout() was entered. 3) e1000_reset_task() was called. Saw the message from e_err() in the console log. 4) e1000_reinit_locked was called. This function calls e1000_down() and e1000_up(). These functions call napi_disable() and napi_enable() respectively. 5) Then on another thread, a monitor task saw carrier was down and executed 'ip set link down' and 'ip set link up' commands. 6) Saw the '_E1000_RESETTING'warning fron the e1000_close function. 7) Either the e1000_open() executed between the e1000_down() and e1000_up() calls in step 4 or the e1000_open() call executed after the e1000_up() call. In either case, napi_enable() is called twice which triggers the BUG_ON.

2011-10-16e1000e: locking bug introduced by commit 67fd4fcbBruce Allan2-8/+14
Commit 67fd4fcb (e1000e: convert to stats64) added the ability to update statistics more accurately and on-demand through the net_device_ops .ndo_get_stats64 hook, but introduced a locking bug on 82577/8/9 when linked at half-duplex (seen on kernels with CONFIG_DEBUG_ATOMIC_SLEEP=y and CONFIG_PROVE_LOCKING=y). The commit introduced code paths that caused a mutex to be locked in atomic contexts, e.g. an rcu_read_lock is held when irqbalance reads the stats from /sys/class/net/ethX/statistics causing the mutex to be locked to read the Phy half-duplex statistics registers. The mutex was originally introduced to prevent concurrent accesses of resources (the NVM and Phy) shared by the driver, firmware and hardware a few years back when there was an issue with the NVM getting corrupted. It was later split into two mutexes - one for the NVM and one for the Phy when it was determined the NVM, unlike the Phy, should not be protected by the software/firmware/hardware semaphore (arbitration of which is done in part with the SWFLAG bit in the EXTCNF_CTRL register). This latter semaphore should be sufficient to prevent resource contention of the Phy in the driver (i.e. the mutex for Phy accesses is not needed), but to be sure the mutex is replaced with an atomic bit flag which will warn if any contention is possible. Also add additional debug output to help determine when the sw/fw/hw semaphore is owned by the firmware or hardware.
