Till GFX8 we can only enable PRT support globally, but with the next hardware generation we can do this on a per page basis. Keep the interface consistent by adding PRT mappings and enable support globally on current hardware when the first mapping is made. v2: disable PRT support delayed and on all error paths v3: PRT and other permissions are mutal exclusive, PRT mappings don't need a BO. v4: update PRT mappings durign CS as well, make va_flags 64bit Signed-off-by: Junwei Zhang <[email protected]> Signed-off-by: Christian König <[email protected]> Reviewed-by: Nicolai Hähnle <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

Add the sysfs entries pp_gfx_power_profile and pp_compute_power_profile which give user a way to set power profile through parameters minimum sclk, minimum mclk, activity threshold, up hysteresis and down hysteresis only when the entry power_dpm_force_performance_level is in default value "auto". It is read and write. Example: echo 500 800 20 0 5 > /sys/class/drm/card0/device/pp_*_power_profile cat /sys/class/drm/card0/device/pp_*_power_profile 500 800 20 0 5 Note: first parameter is sclk in MHz, second is mclk in MHz, third is activity threshold in percentage, fourth is up hysteresis in ms and fifth is down hysteresis in ms. echo set > /sys/class/drm/card0/device/pp_*_power_profile To set power profile state if it exists. echo reset > /sys/class/drm/card0/device/pp_*_power_profile To restore default state and clear previous setting.

From commit 73dec95e6ba3 ("drm/i915: Emit to ringbuffer directly"), copy_gma_to_hva() now returns copied data length instead of 0, so need to change error return check for that. Note: Looks this is caused by backmerge conflict resolving, so 4.11-rc4 is not impacted as commit 73dec95e6ba3 ("drm/i915: Emit to ringbuffer directly") is not in 4.11. But need to fix this before I can apply 4.12 stuff against drm-intel-next correctly.

2017-03-24IB/device: Convert ib-comp-wq to be CPU-boundSagi Grimberg1-2/+1
This workqueue is used by our storage target mode ULPs via the new CQ API. Recent observations when working with very high-end flash storage devices reveal that UNBOUND workqueue threads can migrate between cpu cores and even numa nodes (although some numa locality is accounted for). While this attribute can be useful in some workloads, it does not fit in very nicely with the normal run-to-completion model we usually use in our target-mode ULPs and the block-mq irq<->cpu affinity facilities. The whole block-mq concept is that the completion will land on the same cpu where the submission was performed. The fact that our submitter thread is migrating cpus can break this locality. We assume that as a target mode ULP, we will serve multiple initiators/clients and we can spread the load enough without having to use unbound kworkers. Also, while we're at it, expose this workqueue via sysfs which is harmless and can be useful for debug.

2017-03-24IB/rxe: increment msn only when completing a requestDavid Marchand1-5/+4
According to C9-147, MSN should only be incremented when the last packet of a multi packet request has been received. "Logically, the requester associates a sequential Send Sequence Number (SSN) with each WQE posted to the send queue. The SSN bears a one- to-one relationship to the MSN returned by the responder in each re- sponse packet. Therefore, when the requester receives a response, it in- terprets the MSN as representing the SSN of the most recent request completed by the responder to determine which send WQE(s) can be completed."

2017-03-24IB/core: Restore I/O MMU, s390 and powerpc supportBart Van Assche1-6/+20
Avoid that the following error message is reported on the console while loading an RDMA driver with I/O MMU support enabled: DMAR: Allocating domain for mlx5_0 failed Ensure that DMA mapping operations that use to_pci_dev() to access to struct pci_dev see the correct PCI device. E.g. the s390 and powerpc DMA mapping operations use to_pci_dev() even with I/O MMU support disabled. This patch preserves the following changes of the DMA mapping updates patch series: - Introduction of dma_virt_ops. - Removal of ib_device.dma_ops. - Removal of struct ib_dma_mapping_ops. - Removal of an if-statement from each ib_dma_*() operation. - IB HW drivers no longer set dma_device directly.
