2011-09-28ixgbe: update {P}FC thresholds to account for X540 and loopbackJohn Fastabend
Revise high and low threshold marks wrt flow control to account for the X540 devices and latency introduced by the loopback switch. Without this it was in theory possible to drop frames on a supposedly lossless link with X540 or SR-IOV enabled. Previously we used a magic number in a define to calculate the threshold values. This made it difficult to sort out exactly which latencies were or were not being accounted for. Here I was overly explicit and tried to used #define names that would be recognizable after reading the IEEE 802.1Qbb specification.

2011-09-28ixgbe: Cleanup q_vector interrupt throttle rate logicEmil Tantilov
This patch is meant to help cleanup the interrupt throttle rate logic by storing the interrupt throttle rate as a value in microseconds instead of interrupts per second. The advantage to this approach is that the value can now be stored in an 16 bit field and doesn't require as much math to flip the value back and forth since the hardware already used microseconds when setting the rate.

2011-09-28e1000: don't enable dma receives until after dma address has been setupDean Nelson
Doing an 'ifconfig ethN down' followed by an 'ifconfig ethN up' on a qemu-kvm guest system configured with two e1000 NICs can result in an 'unable to handle kernel paging request at 0000000100000000' or 'bad page map in process ...' or something similar. These result from a 4096-byte page being corrupted with the following two-word pattern (16-bytes) repeated throughout the entire page: 0x0000000000000000 0x0000000100000000 There can be other bits set as well. What is a constant is that the 2nd word has the 32nd bit set. So one could see: : 0x0000000000000000 0x0000000100000000 0x0000000000000000 0x0000000172adc067 <<< bad pte 0x800000006ec60067 0x0000000700000040 0x0000000000000000 0x0000000100000000 : Which came from from a process' page table I dumped out when the marked line was seen as bad by print_bad_pte(). The repeating pattern represents the e1000's two-word receive descriptor: struct e1000_rx_desc { __le64 buffer_addr; /* Address of the descriptor's data buffer */ __le16 length; /* Length of data DMAed into data buffer */ __le16 csum; /* Packet checksum */ u8 status; /* Descriptor status */ u8 errors; /* Descriptor Errors */ __le16 special; }; And the 32nd bit of the 2nd word maps to the 'u8 status' member, and corresponds to E1000_RXD_STAT_DD which indicates the descriptor is done. The corruption appears to result from the following... . An 'ifconfig ethN down' gets us into e1000_close(), which through a number of subfunctions results in: 1. E1000_RCTL_EN being cleared in RCTL register. [e1000_down()] 2. dma_free_coherent() being called. [e1000_free_rx_resources()] . An 'ifconfig ethN up' gets us into e1000_open(), which through a number of subfunctions results in: 1. dma_alloc_coherent() being called. [e1000_setup_rx_resources()] 2. E1000_RCTL_EN being set in RCTL register. [e1000_setup_rctl()] 3. E1000_RCTL_EN being cleared in RCTL register. [e1000_configure_rx()] 4. RDLEN, RDBAH and RDBAL registers being set to reflect the dma page allocated in step 1. [e1000_configure_rx()] 5. E1000_RCTL_EN being set in RCTL register. [e1000_configure_rx()] During the 'ifconfig ethN up' there is a window opened, starting in step 2 where the receives are enabled up until they are disabled in step 3, in which the address of the receive descriptor dma page known by the NIC is still the previous one which was freed during the 'ifconfig ethN down'. If this memory has been reallocated for some other use and the NIC feels so inclined, it will write to that former dma page with predictably unpleasant results. I realize that in the guest, we're dealing with an e1000 NIC that is software emulated by qemu-kvm. The problem doesn't appear to occur on bare-metal. Andy suspects that this is because in the emulator link-up is essentially instant and traffic can start flowing immediately. Whereas on bare-metal, link-up usually seems to take at least a few milliseconds. And this might be enough to prevent traffic from flowing into the device inside the window where E1000_RCTL_EN is set. So perhaps a modification needs to be made to the qemu-kvm e1000 NIC emulator to delay the link-up. But in defense of the emulator, it seems like a bad idea to enable dma operations before the address of the memory to be involved has been made known. The following patch no longer enables receives in e1000_setup_rctl() but leaves them however they were. It only enables receives in e1000_configure_rx(), and only after the dma address has been made known to the hardware. There are two places where e1000_setup_rctl() gets called. The one in e1000_configure() is followed immediately by a call to e1000_configure_rx(), so there's really no change functionally (except for the removal of the problem window. The other is in __e1000_shutdown() and is not followed by a call to e1000_configure_rx(), so there is a change functionally. But consider... . An 'ifconfig ethN down' (just as described above). . A 'suspend' of the system, which (I'm assuming) will find its way into e1000_suspend() which calls __e1000_shutdown() resulting in: 1. E1000_RCTL_EN being set in RCTL register. [e1000_setup_rctl()] And again we've re-opened the problem window for some unknown amount of time.

2011-09-28candev: allow SJW user setting for bittiming calculationOliver Hartkopp
This patch adds support for SJW user settings to not set the synchronization jump width (SJW) to 1 in any case when using the in-kernel bittiming calculation. The ip-tool from iproute2 already supports to pass the user defined SJW value. The given SJW value is sanitized with the controller specific sjw_max and the calculated tseg2 value. As the SJW can have values up to 4 providing this value will lead to the maximum possible SJW automatically. A higher SJW allows higher controller oscillator tolerances.

2011-09-28connector: add comm change event report to proc connectorVladimir Zapolskiy
Add an event to monitor comm value changes of tasks. Such an event becomes vital, if someone desires to control threads of a process in different manner. A natural characteristic of threads is its comm value, and helpfully application developers have an opportunity to change it in runtime. Reporting about such events via proc connector allows to fine-grain monitoring and control potentials, for instance a process control daemon listening to proc connector and following comm value policies can place specific threads to assigned cgroup partitions. It might be possible to achieve a pale partial one-shot likeness without this update, if an application changes comm value of a thread generator task beforehand, then a new thread is cloned, and after that proc connector listener gets the fork event and reads new thread's comm value from procfs stat file, but this change visibly simplifies and extends the matter.

2011-09-27skge: handle irq better on single port cardStephen Hemminger
Most boards with SysKonnect/Marvell Ethernet have only a single port. For the single port case, use the standard Ethernet driver convention of allocating IRQ when device is brought up rather than at probe time. This patch also adds some additional read after writes to avoid any PCI posting problems when setting the IRQ mask. The error handling of dual port cards is also changed. If second port can not be brought up, then just fail. No point in continuing, since the failure is most certainly because of out of memory. It is worth noting that the dual port skge device has a single irq but two seperate status rings and therefore has two NAPI objects, one for each port.

This patch touchs most of the enic port profile handling code. Tried to break it into sub patches without success. The patch mainly does the following: - Port profile operations for a SRIOV VF are modified to work only via its PF - Changes the port profile static struct in struct enic to a pointer. This is because a SRIOV PF has to now hold the port profile information for all its VF's - Moved address registration for VF's during port profile ASSOCIATE time - Most changes in port profile handling code are changes related to indexing into the port profile struct array of a PF for the VF port profile information Signed-off-by: Roopa Prabhu <roprabhu@cisco.com> Signed-off-by: Sujith Sankar <ssujith@cisco.com> Signed-off-by: Christian Benvenuti <benve@cisco.com> Signed-off-by: David Wang <dwang2@cisco.com> Signed-off-by: David S.

We don't need SFP+ plugable support for X540 hardware (copper only) so don't enable the SFP+ interrupts. Signed-off-by: Don Skidmore <donald.c.skidmore@intel.com> Tested-by: Phil Schmitt <phillip.j.schmitt@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2011-09-23ixgbe: DCB, do not call set_state() from IEEE modeJohn Fastabend
The DCB CEE command set_state() will complete successfully but is misleading because it enables IEEE mode. After this patch the command is failed. And IEEE PFC/ETS is managed from ieee paths now instead of using CEE primitives.

2011-09-23ixgbe: Reconfigure SR-IOV InitGreg Rose
Use the PCI device flag indicating if a VF is assigned to a guest VM to guard against destroying VFs upon driver removal. Implement additional feature to detect if VFs already exist when the driver is loaded and if so configure them and set the driver state to SR-IOV enabled.
