2014-06-11drm/nouveau/disp/dp: maintain link in response to hpd signalBen Skeggs6-12/+125
This previously worked for the most part due to userspace doing a modeset in response to HPD interrupts. This will allow us to properly handle cases where sync is lost for other reasons, or if userspace isn't caring. Signed-off-by: Ben Skeggs <[email protected]>

There's also provisions to allow a pad to be locked with a specific routing, for an indefinite period of time. This will be used in future patches. The G94+ pad driver will now also power-down pads when not required. Signed-off-by: Ben Skeggs <[email protected]>
2014-06-11drm/nouveau/i2c: balance port acquire/releaseBen Skeggs4-14/+56
This was a half-finished hack before, just enough to handle the shared aux/i2c pad thing on G94 and up. We got lucky with locking etc up until now, as this was (generally) all protected by the DRM mode_config lock. It's about to become a lot more likely to hit the races.

Hariprasad Shenai says: ==================== Adds support for CIQ and other misc. fixes for rdma/cxgb4 This patch series adds support to allocate and use IQs specifically for indirect interrupts, adds fixes to align ISS for iWARP connections & fixes related to tcp snd/rvd window for Chelsio T4/T5 adapters on iw_cxgb4. Also changes Interrupt Holdoff Packet Count threshold of response queues for cxgb4 driver. The patches series is created against 'net-next' tree. And includes patches on cxgb4 and iw_cxgb4 driver. Since this patch-series contains cxgb4 and iw_cxgb4 patches, we would like to request this patch series to get merged via David Miller's 'net-next' tree. We have included all the maintainers of respective drivers. Kindly review the change and let us know in case of any review comments. ==================== Signed-off-by: David S.

2014-06-10iw_cxgb4: Choose appropriate hw mtu index and ISS for iWARP connectionsHariprasad Shenai5-15/+180
Select the appropriate hw mtu index and initial sequence number to optimize hw memory performance. Add new cxgb4_best_aligned_mtu() which allows callers to provide enough information to be used to [possibly] select an MTU which will result in the TCP Data Segment Size (AKA Maximum Segment Size) to be an aligned value. If an RTR message exhange is required, then align the ISS to 8B - 1 + 4, so that after the SYN the send seqno will align on a 4B boundary. The RTR message exchange will leave the send seqno aligned on an 8B boundary. If an RTR is not required, then align the ISS to 8B - 1. The goal is to have the send seqno be 8B aligned when we send the first FPDU.

2014-06-10iw_cxgb4: Allocate and use IQs specifically for indirect interruptsHariprasad Shenai8-9/+84
Currently indirect interrupts for RDMA CQs funnel through the LLD's RDMA RXQs, which also handle direct interrupts for offload CPLs during RDMA connection setup/teardown. The intended T4 usage model, however, is to have indirect interrupts flow through dedicated IQs. IE not to mix indirect interrupts with CPL messages in an IQ. This patch adds the concept of RDMA concentrator IQs, or CIQs, setup and maintained by the LLD and exported to iw_cxgb4 for use when creating CQs. RDMA CPLs will flow through the LLD's RDMA RXQs, and CQ interrupts flow through the CIQs. Design: cxgb4 creates and exports an array of CIQs for the RDMA ULD. These IQs are sized according to the max available CQs available at adapter init. In addition, these IQs don't need FL buffers since they only service indirect interrupts. One CIQ is setup per RX channel similar to the RDMA RXQs. iw_cxgb4 will utilize these CIQs based on the vector value passed into create_cq(). The num_comp_vectors advertised by iw_cxgb4 will be the number of CIQs configured, and thus the vector value will be the index into the array of CIQs.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-09 This series contains more updates to i40e and i40evf. Shannon adds checks for error status bits on the admin event queue and provides notification if seen. Cleans up unused variable and memory allocation which was used earlier in driver development and is no longer needed. Also fixes the driver to not complain about removing non-existent MAC addresses. Bumps the driver versions for both i40e and i40evf. Catherine fixes a function header comment to make sure the comment correctly reflects the function name. Mitch adds code to allow for additional VSIs since the number of VSIs that the firmware reports to us is a guaranteed minimum, not an absolute maximum. The hardware actually supports for more than the reported value, which we often need. Implements anti-spoofing for VFs for both MAC addresses and VLANs, as well as enable this feature by default for all VFs. Anjali changes the interrupt distribution policy to change the way resources for special features are handled. Fixes the driver to not fall back to one queue if the only feature enabled is ATR, since FD_SB and FD_ATR need to be checked independently in order to decide if we will support multiple queue or not. Allows the RSS table entry range and GPS to be any number, not necessarily a power of 2 because hardware does not restrict us to use a power of 2 GPS in the case of RSS as long as we are not sharing the RSS table with another VSI (VMDq). Frank modifies the driver to keep SR-IOV enabled in the case that RSS, VMFq, FD_SB and DCB are disabled so that SR-IOV does not get turned off unnecessarily. Jesse fixes a bug in receive checksum where the driver was not marking packets with bad checksums correctly, especially IPv6 packets with a bad checksum. To do this correctly, we need a define that may be set by hardware in rare cases. Greg fixes the driver to delete all the old and stale MAC filters for the VF VSI when the host administrator changes the VF MAC address from under its feet. ==================== Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc Pull powerpc updates from Ben Herrenschmidt: "Here is the bulk of the powerpc changes for this merge window. It got a bit delayed in part because I wasn't paying attention, and in part because I discovered I had a core PCI change without a PCI maintainer ack in it. Bjorn eventually agreed it was ok to merge it though we'll probably improve it later and I didn't want to rebase to add his ack. There is going to be a bit more next week, essentially fixes that I still want to sort through and test. The biggest item this time is the support to build the ppc64 LE kernel with our new v2 ABI. We previously supported v2 userspace but the kernel itself was a tougher nut to crack. This is now sorted mostly thanks to Anton and Rusty. We also have a fairly big series from Cedric that add support for 64-bit LE zImage boot wrapper. This was made harder by the fact that traditionally our zImage wrapper was always 32-bit, but our new LE toolchains don't really support 32-bit anymore (it's somewhat there but not really "supported") so we didn't want to rely on it. This meant more churn that just endian fixes. This brings some more LE bits as well, such as the ability to run in LE mode without a hypervisor (ie. under OPAL firmware) by doing the right OPAL call to reinitialize the CPU to take HV interrupts in the right mode and the usual pile of endian fixes. There's another series from Gavin adding EEH improvements (one day we *will* have a release with less than 20 EEH patches, I promise!). Another highlight is the support for the "Split core" functionality on P8 by Michael. This allows a P8 core to be split into "sub cores" of 4 threads which allows the subcores to run different guests under KVM (the HW still doesn't support a partition per thread). And then the usual misc bits and fixes ..." [ Further delayed by gmail deciding that BenH is a dirty spammer.

2014-06-10rbd: only set disk to read-only onceJosh Durgin1-1/+1
rbd_open(), called every time the device is opened, calls set_device_ro(). There's no reason to set the device read-only or read-write every time it is opened.

Adds two trace events which supply the same info that initcall_debug provides, but via ftrace instead of dmesg. The existing initcall_debug calls require the pm_print_times_enabled var to be set (either via sysfs or via the kernel cmd line). The new trace events provide all the same info as the initcall_debug prints but with less overhead, and also with coverage of device prepare and complete device callbacks. These events replace the device_pm_report_time event (which has been removed). device_pm_callback_start is called first and provides the device and callback info. device_pm_callback_end is called after with the device name and error info. The time and pid are gathered from the trace data headers. Signed-off-by: Todd Brandt <[email protected]> Signed-off-by: Rafael J. Wysocki <[email protected]>
