git://people.freedesktop.org/~gabbayo/linux into drm-next - Usermode Events The current events code implemented some data structures (waitqueue, fifo) that were already implemented in the kernel. The patches below addresses this issue by replacing them with the standard kernel implementation. In addition, they simplify allocation of events IDs and memory for the events. The patches also increase the maximum number of events while maintaining compatibility with the older userspace library. - Remove radeon support Because Kaveri is fully supported in amdgpu and because current and future versions of userspace libraries will only support amdgpu, we removed radeon support from kfd. Current users can move to amdgpu while using the same userspace libraries. - Various bug fixes and cleanups * tag 'drm-amdkfd-next-2017-11-02' of git://people.freedesktop.org/~gabbayo/linux: (26 commits) drm/amdkfd: Minor cleanups drm/amdkfd: Update queue_count before mapping queues drm/amdkfd: Cleanup DQM ASIC-specific ops drm/amdkfd: Register/Deregister process on qpd resolution drm/amdkfd: Fix debug unregister procedure on process termination drm/amdkfd: Avoid calling amd_iommu_unbind_pasid() when suspending drm/amdkfd: Disable CP/SDMA ring/doorbell in MQD drm/amdkfd: Clean up the data structure in kfd_process drm/radeon: deprecate and remove KFD interface drm/amdkfd: use a high priority workqueue for IH work drm/amdkfd: wait only for IH work on IH exit drm/amdkfd: increase IH num entries to 8192 drm/amdkfd: use standard kernel kfifo for IH drm/amdkfd: increase limit of signal events to 4096 per process drm/amdkfd: Make event limit dependent on user mode mapping size drm/amdkfd: Use IH context ID for signal lookup drm/amdkfd: Simplify event ID and signal slot management drm/amdkfd: Simplify events page allocator drm/amdkfd: Use wait_queue_t to implement event waiting drm/amdkfd: remove redundant kfd_event_waiter.input_index ...

The fan control mode can either be FDO_PWM_MODE_STATIC or FDO_PWM_MODE_STATIC_RPM. Setting it as AMD_FAN_CTRL_AUTO will cause the fan spin faster wrongly. This can be reproduced by: '# cat /sys/class/hwmon/hwmon0/pwm1 38 '# cat /sys/class/hwmon/hwmon0/pwm1_enable 2 '# echo "2" > /sys/class/hwmon/hwmon0/pwm1_enable '# cat /sys/class/hwmon/hwmon0/pwm1 122 The fan speed get faster wrongly even with its original mode echo back.

2017-11-01drm/amdkfd: Avoid calling amd_iommu_unbind_pasid() when suspendingYong Zhao1-9/+5
When kfd suspending on APU, we do not need to call amd_iommu_unbind_pasid(), because pasid will be unbound automatically when power goes off. On the other hand, calling amd_iommu_unbind_pasid() will trigger kfd_process_iommu_unbind_callback() if the process is not terminating. By design, kfd_process_iommu_unbind_callback() should only be called for process terminating. So we would rather not to call amd_iommu_unbind_pasid() when suspending.

2017-10-31drm/radeon: fix atombios on big endianRoman Kapl1-20/+18
The function for byteswapping the data send to/from atombios was buggy for num_bytes not divisible by four. The function must be aware of the fact that after byte-swapping the u32 units, valid bytes might end up after the num_bytes boundary. This patch was tested on kernel 3.12 and allowed us to sucesfully use DisplayPort on and Radeon SI card. Namely it fixed the link training and EDID readout. The function is patched both in radeon and amd drivers, since the functions and the fixes are identical.
