2017-11-01drm/amd/powerplay: wrong control mode cause the fan spins faster unnecessarilyEvan Quan1-1/+1
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.
