intel drivers: repair missing flush operations

2011-08-04T11:59:07+00:00

after review of all intel drivers, found several instances where drivers had the incorrect pattern of: memory mapped write(); delay(); which should always be: memory mapped write(); write flush(); /* aka memory mapped read */ delay(); explanation: The reason for including the flush is that writes can be held (posted) in PCI/PCIe bridges, but the read always has to complete synchronously and therefore has to flush all pending writes to a device. If a write is held and followed by a delay, the delay means nothing because the write may not have reached hardware (maybe even not until the next read) Signed-off-by: Jesse Brandeburg Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

e1000e: disable far-end loopback mode on ESB2

2011-06-10T03:31:24+00:00

The ESB2 LAN includes a debug feature that enables far-end loopback (FELB) of the SerDes/Kumeran interface. This feature is activated when receiving a sequence of symbols that includes a reserved codeword. On a perfect link, FELB would never be activated. In the presence of bit errors, there is a very small, but non-zero, probability of FELB being activated. If the FELB is activated, the SerDes link becomes non-functional and must be reset. It could also corrupt the switching tables in the switch since the ESB2 is transmitting packets with a different source MAC address. This patch disables the FELB feature.

e1000e: implement ethtool set_phys_id

2011-04-27T09:05:53+00:00

Based on a patch from Stephen Hemminger . The new ethtool set_phys_id takes over controlling the LED for identifying boards. This fixes the lockout during that period. For this device lots of extra infrastructure can also be removed by using set_phys_id. v2: - return blink frequency for parts that do not support blink in h/w - add blink_led function pointers for devices that do support blink in h/w to cleanup the test for this functionality Signed-off-by: Bruce Allan Cc: Stephen Hemminger Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

e1000e: convert short duration msleep() to usleep_range()

2011-04-14T02:17:06+00:00

With durations less than 20ms, the jiffies or legacy timer backed msleep() may sleep ~20ms which might not be what the caller expects. Instead, it is recommended to use the hrtimers backed usleep_range(). For more, see Documentation/timers/timers-howto.txt. Issues reported by checkpatch. In addition, remove unnecessary sleep in e1000e_write_nvm_spi(). Signed-off-by: Bruce Allan Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

e1000e: cleanup variables set but not used

2011-01-10T07:44:06+00:00

The ICR register is clear on read and we don't care what the returned value is when resetting the hardware so the icr variable(s) can be removed. We should not ignore the return from e1000_lv_jumbo_workaround_ich8lan() and from e1000_get_phy_id_82571() (dump a debug message when it fails and when an unknown Phy id is returned).

e1000e: use hardware writeback batching

2010-10-01T00:59:31+00:00

Most e1000e parts support batching writebacks. The problem with this is that when some of the TADV or TIDV timers are not set, Tx can sit forever. This is solved in this patch with write flushes using the Flush Partial Descriptors (FPD) bit in TIDV and RDTR. This improves bus utilization and removes partial writes on e1000e, particularly from 82571 parts in S5500 chipset based machines. Only ES2LAN and 82571/2 parts are included in this optimization, to reduce testing load. Signed-off-by: Jesse Brandeburg Tested-by: Emil Tantilov Signed-off-by: Jeff Kirsher Signed-off-by: David S.
