2011-07-22IB/qib: Defer HCA error events to taskletMike Marciniszyn2-21/+53
With ib_qib options: options ib_qib krcvqs=1 pcie_caps=0x51 rcvhdrcnt=4096 singleport=1 ibmtu=4 a run of ib_write_bw -a yields the following: ------------------------------------------------------------------ #bytes #iterations BW peak[MB/sec] BW average[MB/sec] 1048576 5000 2910.64 229.80 ------------------------------------------------------------------ The top cpu use in a profile is: CPU: Intel Architectural Perfmon, speed 2400.15 MHz (estimated) Counted CPU_CLK_UNHALTED events (Clock cycles when not halted) with a unit mask of 0x00 (No unit mask) count 1002300 Counted LLC_MISSES events (Last level cache demand requests from this core that missed the LLC) with a unit mask of 0x41 (No unit mask) count 10000 samples % samples % app name symbol name 15237 29.2642 964 17.1195 ib_qib.ko qib_7322intr 12320 23.6618 1040 18.4692 ib_qib.ko handle_7322_errors 4106 7.8860 0 0 vmlinux vsnprintf Analysis of the stats, profile, the code, and the annotated profile indicate: - All of the overflow interrupts (one per packet overflow) are serviced on CPU0 with no mitigation on the frequency. - All of the receive interrupts are being serviced by CPU0. (That is the way truescale.cmds statically allocates the kctx IRQs to CPU) - The code is spending all of its time servicing QIB_I_C_ERROR RcvEgrFullErr interrupts on CPU0, starving the packet receive processing. - The decode_err routine is very inefficient, using a printf variant to format a "%s" and continues to loop when the errs mask has been cleared. - Both qib_7322intr and handle_7322_errors read pci registers, which is very inefficient. The fix does the following: - Adds a tasklet to service QIB_I_C_ERROR - Replaces the very inefficient scnprintf() with a memcpy(). A field is added to qib_hwerror_msgs to save the sizeof("string") at compile time so that a strlen is not needed during err_decode(). - The most frequent errors (Overflows) are serviced first to exit the loop as early as possible. - The loop now exits as soon as the errs mask is clear rather than fruitlessly looping through the msp array. With this fix the performance changes to: ------------------------------------------------------------------ #bytes #iterations BW peak[MB/sec] BW average[MB/sec] 1048576 5000 2990.64 2941.35 ------------------------------------------------------------------ During testing of the error handling overflow patch, it was determined that some CPU's were slower when servicing both overflow and receive interrupts on CPU0 with different MSI interrupt vectors. This patch adds an option (krcvq01_no_msi) to not use a dedicated MSI interrupt for kctx's < 2 and to service them on the default interrupt. For some CPUs, the cost of the interrupt enter/exit is more costly than then the additional PCI read in the default handler.

2011-07-21ixgbe: only enable WoL for magic packet by defaultAndy Gospodarek1-6/+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.

2011-07-21ixgbe: Pass staterr instead of re-reading status and error bits from descriptorAlexander Duyck3-42/+37

2011-07-21ixgbe: Move interrupt related values out of ring and into q_vectorAlexander Duyck3-138/+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.

2011-07-21ixgbe: add structure for containing RX/TX rings to q_vectorAlexander Duyck3-84/+88
This patch adds support for a ring container structure to be used within the q_vector. The basic idea is to provide a means of separating the RX and TX rings while maintaining a common structure for their containment. The advantage to this is that later we should be able to pass this structure to the update_itr functions without needing to pass individual rings.

2011-07-22lguest: Simplify device initialization.Rusty Russell1-15/+22
We used to notify the Host every time we updated a device's status. However, it only really needs to know when we're resetting the device, or failed to initialize it, or when we've finished our feature negotiation. In particular, we used to wait for VIRTIO_CONFIG_S_DRIVER_OK in the status byte before starting the device service threads. But this corresponds to the successful finish of device initialization, which might (like virtio_blk's partition scanning) use the device. So we had a hack, if they used the device before we expected we started the threads anyway. Now we hook into the finalize_features hook in the Guest: at that point we tell the Launcher that it can rely on the features we have acked. On the Launcher side, we look at the status at that point, and start servicing the device. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2011-07-22lguest: use a special 1:1 linear pagetable mode until first switch.Rusty Russell2-194/+86
The Host used to create some page tables for the Guest to use at the top of Guest memory; it would then tell the Guest where this was. In particular, it created linear mappings for 0 and 0xC0000000 addresses because lguest used to switch to its real page tables quite late in boot. However, since d50d8fe19 Linux initialized boot page tables in head_32.S even before the "are we lguest?" boot jump. So, now we can simplify things: the Host pagetable code assumes 1:1 linear mapping until it first calls the LHCALL_NEW_PGTABLE hypercall, which we now do before we reach C code. This also means that the Host doesn't need to know anything about the Guest's PAGE_OFFSET. (Non-Linux guests might not even have such a thing). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2011-07-21stmmac: unify MAC and PHY configuration parameters (V2)Giuseppe CAVALLARO3-119/+65
Prior to this change, most PHY configuration parameters were passed into the STMMAC device as a separate PHY device. As well as being unusual, this made it difficult to make changes to the MAC/PHY relationship. This patch moves all the PHY parameters into the MAC configuration structure, mainly as a separate structure. This allows us to completely ignore the MDIO bus attached to a stmmac if desired, and not create the PHY bus. It also allows the stmmac driver to use a different PHY from the one it is connected to, for example a fixed PHY or bit banging PHY. Also derive the stmmac/PHY connection type (MII/RMII etc) from the mode can be passed into <platf>_configure_ethernet. STLinux kernel at git://git.stlinux.com/stm/linux-sh4-2.6.32.y.git provides several examples how to use this new infrastructure (that actually is easier to maintain and clearer).

2011-07-21jme: Fix unmap error (Causing system freeze)Guo-Fu Tseng1-6/+14
This patch add the missing dma_unmap(). Which solved the critical issue of system freeze on heavy load. Michal Miroslaw's rejected patch: [PATCH v2 10/46] net: jme: convert to generic DMA API Pointed out the issue also, thank you Michal. But the fix was incorrect. It would unmap needed address when low memory. Got lots of feedback from End user and Gentoo Bugzilla. https://bugs.gentoo.org/show_bug.cgi?id=373109 Thank you all. :) Cc: stable@kernel.org Signed-off-by: Guo-Fu Tseng <cooldavid@cooldavid.org> Acked-by: Chris Wright <chrisw@sous-sol.org> Signed-off-by: David S.
