* intel drivers: repair missing flush operationsJesse Brandeburg2011-08-045-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | 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 <jesse.brandeburg@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

This was based on the original patch submitted by Michal Miroslaw <mirq-linux@rere.qmqm.pl>. I also removed the special case not requiring a reset for X540 hardware. It is needed just as it is in 82599 hardware.

* ixgbe: only enable WoL for magic packet by defaultAndy Gospodarek2011-07-211-6/+3
| | | | | | | | | | | | | | | | | | | | | | | Martin Wilck <martin.wilck@ts.fujitsu.com> reported that systems using the ixgbe-driver that were capable of WoL were rebooting almost as soon as they were shut down. This is because the default WoL settings enabled magic packet, broadcast, unicast, and multicast. Other Intel devices seem to use the stored eeprom value for initial WoL capabilities. The 82578DM (e1000e) and 82576 (igb) the devices I looked at had only the magic packet enabled in the eeprom, so that seems appropriate on ixgbe-based devices as well. I set the WoL options on my 82578DM to be the same default as the ixgbe devices (umbg) and saw the same as Martin -- almost as soon as my box shutdown, it booted again. This patch changes the default to only be the magic packet. This is the same as the default for most Intel and non-Intel hardware currently upstream.

* ixgbe: Move interrupt related values out of ring and into q_vectorAlexander Duyck2011-07-213-138/+62
| | | | | | | | | | | | | This change moves work_limit, total_packets, and total_bytes into the ring container struct of the q_vector. The advantage of this is that it should reduce the size of memory used in the event of multiple rings being assigned to a single q_vector. In addition it should help to reduce the total workload for calculating itr since now total_packets and total_bytes will be the total work done of the interrupt instead of for the ring.

It also allowed the set hardware routines to use both IEEE 802.1Qaz app types and CEE app types. This added code to do bit shifting in the IEEE case. This patch reverts the checks and handles the IEEE case from the setapp entry point. I prefer this because it keeps the two paths from having to be aware of the DCB mode. This resolves a bug where I missed setting the selector bit in the IEEE spec value and left it in the CEE value. Now that they are separate routines these types of errors should not occur.

| | | | | | | | | | | | | | | | | | | | | | | | The number of TX and RX queues allocated depends on the device type, the current features set, online CPUs, and various compile flags. To enable DCB with multiple queues and allow it to coexist with all the features currently implemented it has to setup a valid queue count. This is done at init time using the FDIR and RSS max queue counts and allowing each TC to allocate a queue per CPU. DCB will now use available queues up to (8 x TCs) this is somewhat arbitrary cap but allows DCB to use up to 64 queues. Its easy to increase this later if that is needed. This is prep work to enable Flow Director with DCB. After this DCB can easily coexist with existing features and no longer needs its own DCB feature ring.

* ixgbe: configure minimal packet buffers to support TCJohn Fastabend2011-06-213-114/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | ixgbe devices support different numbers of packet buffers either 8 or 4. Here we only allocate the minimal number of packet buffers required to implement the net_devices number of traffic classes. Fewer traffic classes allows for larger packet buffers in hardware. Also more Tx/Rx queues can be given to each traffic class. This patch is mostly about propagating the number of traffic classes through the init path. Specifically this adds the 4TC cases to the MRQC and MTQC setup routines. Also ixgbe_setup_tc() was sanitized to handle other traffic class value. Finally changing the number of packet buffers in the hardware requires the device to reinit. So this moves the reinit work from DCB into the main ixgbe_setup_tc() routine to consolidate the reset code. Now dcbnl_xxx ops call ixgbe_setup_tc() to configure packet buffers if needed.

The DCB path fixes the DCB configuration by configuring the SECTXMINIFG gap which is required for DCB pause to operate correctly. This patch reduces the duplicate code and does all setup in ixgbe_setup_mtqc() and ixgbe_setup_mrqc(). Additionally, this removes the IXGBE_QDE. This write never set the WRITE bit in the register so the write was not actually doing anything. Also this was to clear the register but, it is never set and defaults to zero. If this is needed for SRIOV it should be added correctly in a follow up patch. But it's never been working so removing it here should be OK.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After discovering that wide use of prefetch on modern CPUs could be a net loss instead of a win, net drivers which were relying on the implicit inclusion of prefetch.h via the list headers showed up in the resulting cleanup fallout. Give them an explicit include via the following $0.02 script. ========================================= #!/bin/bash MANUAL="" for i in `git grep -l 'prefetch(.*)' .` ; do grep -q '<linux/prefetch.h>' $i if [ $? = 0 ] ; then continue fi ( echo '?^#include <linux/?a' echo '#include <linux/prefetch.h>' echo . echo w echo q ) | ed -s $i > /dev/null 2>&1 if [ $? != 0 ]; then echo $i needs manual fixup MANUAL="$i $MANUAL" fi done echo ------------------- 8\<---------------------- echo vi $MANUAL ========================================= Signed-off-by: Paul <paul.gortmaker@windriver.com> [ Fixed up some incorrect #include placements, and added some non-network drivers and the fib_trie.c case - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
