2012-05-10watchdog: shwdt: Use finer grained clock control.Paul Mundt
The clk enable/disable pairs can be pushed down to start/stop rather than probe/remove, along with the runtime PM callsites. This will allow us to keep the block powered off until userspace comes along and decides to do something with it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2012-05-10watchdog: shwdt: Basic clock framework support.Paul Mundt
This plugs in basic clock framework support for the watchdog. As it's an optional MSTP bit, we don't particularly care if a platform has provided it or not, though a valid clock will need to be available for the more complex overflow period calculations found on newer parts -- this will be addressed later.

The current value of the udelay timeout for ixgbe_disable_rx_buff is too short. This causes the security path to not not be properly disabled during the section that is meant to have it turned off.

2012-05-09ixgbe: Enable timesync clock-out feature for PPS support on X540Jacob E Keller
This patch enables the PPS system in the PHC framework, by enabling the clock-out feature on the X540 device. Causes the SDP0 to be set as a 1Hz clock. Also configures the timesync interrupt cause in order to report each pulse to the PPS via the PHC framework, which can be used for general system clock synchronization. (This allows a stable method for tuning the general system time via the on-board SYSTIM register based clock.)

2012-05-09ixgbe: Hardware Timestamping + PTP Hardware Clock (PHC)Jacob Keller
This patch enables hardware timestamping for use with PTP software by extracting a ns counter from an arbitrary fixed point cycles counter. The hardware generates SYSTIME registers using the DMA tick which changes based on the current link speed. These SYSTIME registers are converted to ns using the cyclecounter and timecounter structures provided by the kernel. Using the SO_TIMESTAMPING api, software can enable and access timestamps for PTP packets. The SO_TIMESTAMPING API has space for 3 different kinds of timestamps, SYS, RAW, and SOF. SYS hardware timestamps are hardware ns values that are then scaled to the software clock. RAW hardware timestamps are the direct raw value of the ns counter. SOF software timestamps are the software timestamp calculated as close as possible to the software transmit, but are not offloaded to the hardware. This patch only supports the RAW hardware timestamps due to inefficiency of the SYS design. This patch also enables the PHC subsystem features for atomically adjusting the cycle register, and adjusting the clock frequency in parts per billion. This frequency adjustment works by slightly adjusting the value added to the cycle registers each DMA tick. This causes the hardware registers to overflow rapidly (approximately once every 34 seconds, when at 10gig link). To solve this, the timecounter structure is used, along with a timer set for every 25 seconds. This allows for detecting register overflow and converting the cycle counter registers into ns values needed for providing useful timestamps to the network stack. Only the basic required clock functions are supported at this time, although the hardware supports some ancillary features and these could easily be enabled in the future. Note that use of this hardware timestamping requires modifying daemon software to use the SO_TIMESTAMPING API for timestamps, and the ptp_clock PHC framework for accessing the clock. The timestamps have no relation to the system time at all, so software must use the posix clock generated by the PHC framework instead.

2012-05-09ixgbe: Set Drop_EN bit when multiple Rx queues are present w/o flow controlAlexander Duyck
The drop enable bit can be used to improve the performance of the adapter in the case of multiple queues being present. This performance gain is due to the fact that some slower CPUs can cause the FIFO to backfill preventing faster CPUs from receiving additional work. By setting the drop enable bit we prevent this and instead just drop the packets that would have been bound for the slower CPU.

2012-05-09ixgbe: Clean up priority based flow controlAlexander Duyck
This change cleans up the logic in the priority based flow control configuration routines. Both the 82599 and 82598 based routines perform similar functions however they are both arranged completely differently. This patch goes over both of them to clean up the code. In addition I am dropping the ixgbe_fc_pfc flow control mode and instead just replacing it with checks for if priority flow control is enabled. This allows us to maintain some of the link flow control information which allows for an easier transition between link and priority flow control.

Commit 625d693e9784f988371e69c2b41a2172c0be6c11 (linux-next) "sparc64: Convert over to NO_BOOTMEM." causes the following compile failure for sparc64 allnoconfig: arch/sparc/mm/init_64.c:822:16: error: unused variable 'paddr' arch/sparc/mm/init_64.c:1759:7: error: unused variable 'node' arch/sparc/mm/init_64.c:809:12: error: 'memblock_nid_range' defined but not used The paddr decl can easily be shuffled within the ifdef. The memblock_nid_range is just a stub function for when NEED_MULTIPLE_NODES is off, but the only caller is within a NEED_MULTIPLE_NODES enabled section, so we can simply delete it. The unused "node" is slightly more interesting. In the case of "# CONFIG_NEED_MULTIPLE_NODES is not set" we no longer get the definition of: #define NODE_DATA(nid) (node_data[nid]) from arch/sparc/include/asm/mmzone.h - but instead we get: #define NODE_DATA(nid) (&contig_page_data) from include/linux/mmzone.h -- and since the arg is ignored, the thing really is unused. Rather than put in a confusing looking __maybe_unused, simply splitting the declaration from the assignment seemed to me to be the least offensive. Cc: Sam Ravnborg <sam@ravnborg.org> Cc: "David S.

2012-05-09netxen_nic: Fix estimation of recv MSS in case of LRORajesh Borundia
o Linux stack estimates MSS from skb->len or skb_shinfo(skb)->gso_size. In case of LRO skb->len is aggregate of len of number of packets hence MSS obtained using skb->len would be incorrect. Incorrect estimation of recv MSS would lead to delayed acks in some traffic patterns (which sends two or three packets and wait for ack and only then send remaining packets). This leads to drop in performance. Hence we need to set gso_size to MSS obtained from firmware. o This is fixed recently in firmware hence the MSS is obtained based on capability. If fw is capable of sending the MSS then only driver sets the gso_size. Signed-off-by: Rajesh Borundia <rajesh.borundia@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
