2018-10-30drm/amd/display: set backlight level limit to 1Guttula, Suresh
This patch will work as workaround for silicon limitation related to PWM dutycycle when the backlight level goes to 0. Actually PWM value is 16 bit value and valid range from 1-65535. when ever user requested to set this PWM value to 0 which is not fall in the range, in VBIOS taken care this by limiting to 1. This patch here will do the same. Either driver or VBIOS can not pass 0 value as it is not a valid range for PWM and it will give a high PWM pulse which is not the intended behaviour as per HW constraints.

[Why] Carrizo and Stoney have severe corruption when trying to power 4k 60 monitors over HDMI connectors that support 4k 60. Carrizo and Stoney require retimers and redrivers to support 4k 60 over HDMI. This driver does not currently support these.

2018-10-22drm/amd/pp: enable power limit increase in OD modeJoseph Greathouse
OverDrive mode allows users to increase the maximum SCLK and MCLK frequencies beyond the default on the GPU. However, this may not results in large performance gains if the GPU then runs into its TDP power limit. This patch adds the capability to increase the power limit of a GPU above its default maximum. This is only allowed when overdrive is enabled in the ppfeaturemask, since this is an overdrive feature. The TDPODLimit value from the VBIOS describes how how much higher the TDP should be allowed to go over its default, in percentage. v2: Moved dereference of hwmgr to after its validity check Signed-off-by: Joseph Greathouse <Joseph.Greathouse@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2018-10-16drm/amd/amdgpu: Fix debugfs error handlingDan Carpenter
The error handling is wrong and "ent" could be NULL we when dereference it to get "ent->d_inode". The thing is that normally debugfs_create_file() is not supposed to require (or have) any error handling. That function does return error pointers if debugfs is turned off but we know it's enable here. When it's enabled, then it returns NULL on error. So what I did was I stripped out all the error handling except around the i_size_write(). I could have just used a NULL check instead of an IS_ERR_OR_NULL() but I figured this was more clear because that way you don't have to look at the surrounding code to see whether debugfs is enabled or not.
