2015-02-09drm/exynos: remove exynos_plane_dpmsJoonyoung Shim2-28/+6
The exynos_plane_dpms function handles enabled flag of exynos plane and calls internal hw driver callback function for hw overlay on/off. But it causes state disharmory problem currently and is will be obstacle to apply atomic operation later to keep non-standard per-plane dpms state like enabled flag. Let's remove enabled flag, it just stop to recall internal callback function but hw drivers can handle it properly. And call internal callback function directly then we can remove unnecessary exynos_plane_dpms function Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

2015-02-09drm/exynos: Remove exynos_plane_dpms() call with no effectGustavo Padovan1-2/+0
exynos_plane_dpms(DRM_MODE_DPMS_ON) calls the win_enable()'s callback from the underlying layer. However neither one of these layers implement win_enable() - FIMD, Mixer and VIDI. Thus the call to exynos_plane_dpms() is pointless.

2015-02-09drm/i915: Correct the IOSF Dev_FN field for IOSF transfersShobhit Kumar1-13/+13
As per the specififcation, the SB_DevFn is the PCI_DEVFN of the target device and not the source. So PCI_DEVFN(2,0) is not correct. Further the port ID should be enough to identify devices unless they are MFD. The SB_DevFn was intended to remove ambiguity in case of these MFD devices. For non MFD devices the recommendation for the target device IP was to ignore these fields, but not all of them followed the recommendation. Some like CCK ignore these fields and hence PCI_DEVFN(2, 0) works and so does PCI_DEVFN(0, 0) as it works for DPIO. The issue came to light because of GPIONC which was not getting programmed correctly with PCI_DEVFN(2, 0). It turned out that this did not follow the recommendation and expected 0 in this field. In general the recommendation is to use SB_DevFn as PCI_DEVFN(0, 0) for all devices except target PCI devices.

When the module is being unloaded, don't wait for the PF to politely handle all of our admin queue requests, as that might take forever with a lot of VFs enabled. Instead, just stop everything and request a VF reset. When the original shutdown code was written, VF resets were unreliable, so we avoided them. But with production hardware and firmware, and the 1.x PF driver, this is no longer the case. This fixes a potential multi-minute delay on driver unload, VF disable, or system shutdown.

2015-02-09i40e: add locking around VF resetMitch Williams2-6/+8
During VF deallocation, we need to lock out the VF reset code. However, we cannot depend on simply masking the interrupt, as this does not lock out the service task, which can still call the reset routine. Instead, leave the interrupt enabled, but add locking around the VF disable and reset routines. For the disable code, we wait to get the lock, as the reset code will take a finite amount of time to run. For the reset code, we just return if we fail to get the lock. Since we know that the VFs are being disabled, we don't need to handle the reset. This fixes a panic when disabling SR-IOV.

2015-02-09net: rfs: add hash collision detectionEric Dumazet1-4/+1
Receive Flow Steering is a nice solution but suffers from hash collisions when a mix of connected and unconnected traffic is received on the host, when flow hash table is populated. Also, clearing flow in inet_release() makes RFS not very good for short lived flows, as many packets can follow close(). (FIN , ACK packets, ...) This patch extends the information stored into global hash table to not only include cpu number, but upper part of the hash value. I use a 32bit value, and dynamically split it in two parts. For host with less than 64 possible cpus, this gives 6 bits for the cpu number, and 26 (32-6) bits for the upper part of the hash. Since hash bucket selection use low order bits of the hash, we have a full hash match, if /proc/sys/net/core/rps_sock_flow_entries is big enough. If the hash found in flow table does not match, we fallback to RPS (if it is enabled for the rxqueue). This means that a packet for an non connected flow can avoid the IPI through a unrelated/victim CPU. This also means we no longer have to clear the table at socket close time, and this helps short lived flows performance.

2015-02-08be2net: use offset based FW flashing for Skyhawk chipVasundhara Volam3-23/+66
While sending FW update cmds to the FW, the driver specifies the "type" of each component that needs to be flashed. The FW then picks the offset in the flash area at which the componnet is to be flashed. This doesn't work when new components that the current FW doesn't recognize, need to be flashed. Recent FWs (10.2 and above) support a scheme of FW-update wherein the "offset" of the component in the flash area can be specified instead of the "type".

2015-02-08be2net: avoid flashing SH-B0 UFI image on SH-P2 chipVasundhara Volam2-2/+9
Skyhawk-B0 FW UFI is not compatible to flash on Skyhawk-P2 ASIC. But, Skyhawk-P2 FW UFI is compatible with both B0 and P2 chips. Signed-off-by: Vasundhara Volam <vasundhara.volam@emulex.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-02-08be2net: refactor code that checks flash file compatibilityVasundhara Volam2-68/+78
This patch re-factors the code that checks for flash file compatibility with the chip type, for better readability, as follows: - be_get_ufi_type() returns the UFI type from the flash file - be_check_ufi_compatibility() checks if the UFI type is compatible with the adapter/chip that is being flashed Signed-off-by: Vasundhara Volam <vasundhara.volam@emulex.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2015-02-08be2net: move un-exported routines from be.h to respective src filesSathya Perla3-166/+167
Routines that are called only inside one src file must remain in that file itself. Including them in a header file that is used for exporting routine/struct definitions, causes unnecessary compilation of other src files, when such a routine is modified.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-02-05 This series contains updates to fm10k, ixgbe and ixgbevf. Matthew fixes an issue where fm10k does not properly drop the upper-most four bits on of the VLAN ID due to type promotion, so resolve the issue by not masking off the bits, but by throwing an error if the VLAN ID is out-of-bounds. Then cleans up two cases where variables were not being used, but were being set, so just remove the unused variables. Don cleans up sparse errors in the x550 family file for ixgbe. Fixed up a redundant setting of the default value for set_rxpba, which was done twice accidentally. Cleaned up the probe routine to remove a redundant attempt to identify the PHY, which could lead to a panic on x550. Added support for VXLAN receive checksum offload in x550 hardware. Added the Ethertype Anti-spoofing feature for affected devices. Emil enables ixgbe and ixgbevf to allow multiple queues in SRIOV mode. Adds RSS support for x550 per VF. Fixed up a couple of issues introduced in commit 2b509c0cd292 ("ixgbe: cleanup ixgbe_ndo_set_vf_vlan"), fixed setting of the VLAN inside ixgbe_enable_port_vlan() and disable the "hide VLAN" bit in PFQDE when port VLAN is disabled. Cleaned up the setting of vlan_features by enabling all features at once. Fixed the ordering of the shutdown patch so that we attempt to shutdown the rings more gracefully. We shutdown the main Rx filter in the case of Rx and we set the carrier_off state in the case of Tx so that packets stop being delivered from outside the driver. Then we shutdown interrupts and NAPI, then finally stop the rings from performing DMA and clean them. Added code to allow for Tx hang checking to provide more robust debug info in the event of a transmit unit hang in ixgbevf. Cleaned up ixgbevf logic dealing with link up/down by breaking down the link detection and up/down events into separate functions, similar to how these events are handled in other drivers. Combined the ixgbevf reset and watchdog tasks into a single task so that we can avoid multiple schedules of the reset task when we have a reset event needed due to either the mailbox going down or transmit packets being present on a link down. v2: Fixed up patch #03 of the series to remove the variable type change based on feedback from David Laight ==================== Signed-off-by: David S.
