2021-03-23drm/amdgpu: Set GTT_USWC flag to enable freesync v2Shashank Sharma
This patch sets 'AMDGPU_GEM_CREATE_CPU_GTT_USWC' as input parameter flag, during object creation of an imported DMA buffer. In absence of this flag: 1. Function amdgpu_display_supported_domains() doesn't add AMDGPU_GEM_DOMAIN_GTT as supported domain. 2. Due to which, Function amdgpu_display_user_framebuffer_create() refuses to create framebuffer for imported DMA buffers. 3. Due to which, AddFB() IOCTL fails. 4. Due to which, amdgpu_present_check_flip() check fails in DDX 5. Due to which DDX driver doesn't allow flips (goes to blitting) 6. Due to which setting Freesync/VRR property fails for PRIME buffers. So, this patch finally enables Freesync with PRIME buffer offloading. v2 (chk): instead of just checking the flag we copy it over if the exporter is an amdgpu device as well.

2021-03-23drm/amd/pm: Enable user min/max gfxclk on aldebaranLijo Lazar
Aldebaran has fine grained DPM for GFXCLK. Instead of a discrete level, user can specify a min/max range of GFXCLK for any profiling/tuning purpose.This option is available only in manual performance level mode. Select "manual" as power_dpm_force_performance_level and specify the min/max range using pp_dpm_sclk sysfs node. User cannot specify a min/max range outside of the default min/max range of the ASIC. If specified outside the range, values will be bound by the default min/max range. Ex: To use gfxclk min = 600MHz and max = 900MHz echo manual > /sys/bus/pci/devices/.../power_dpm_force_performance_level echo min 600 max 900 > /sys/bus/pci/devices/.../pp_dpm_sclk Signed-off-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
