and dvi connectors amdgpu_connector_vga_get_modes missed function amdgpu_get_native_mode which assign amdgpu_encoder->native_mode with *preferred_mode result in amdgpu_encoder->native_mode.clock always be 0. That will cause amdgpu_connector_set_property returned early on: if ((rmx_type != DRM_MODE_SCALE_NONE) && (amdgpu_encoder->native_mode.clock == 0)) when we try to set scaling mode Full/Full aspect/Center. Add the missing function to amdgpu_connector_vga_get_mode can fix this. It also works on dvi connectors because amdgpu_connector_dvi_helper_funcs.get_mode use the same method.

2021-11-11mm/migrate.c: remove MIGRATE_PFN_LOCKEDAlistair Popple2-4/+2
MIGRATE_PFN_LOCKED is used to indicate to migrate_vma_prepare() that a source page was already locked during migrate_vma_collect(). If it wasn't then the a second attempt is made to lock the page. However if the first attempt failed it's unlikely a second attempt will succeed, and the retry adds complexity. So clean this up by removing the retry and MIGRATE_PFN_LOCKED flag. Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag set, but nothing actually checks that.

2021-11-09drm/amd/display: Don't lock connection_mutex for DMUB HPDNicholas Kazlauskas1-4/+0
[Why] Per DRM spec we only need to hold that lock when touching connector->state - which we do not do in that handler. Taking this locking introduces unnecessary dependencies with other threads which is bad for performance and opens up the potential for a deadlock since there are multiple locks being held at once. [How] Remove the connection_mutex lock/unlock routine and just iterate over the drm connectors normally. The iter helpers implicitly lock the connection list so this is safe to do. DC link access also does not need to be guarded since the link table is static at creation - we don't dynamically add or remove links, just streams.

2021-11-09drm/amdkfd: lower the VAs base offset to 8KBAlex Sierra1-1/+1
The low 16MB of virtual address space are currently reserved for kernel mode allocations mapped into user virtual address space. This causes conflicts with HMM/SVM mappings at low virtual addresses. We tried to move those kernel mode allocations to the upper half of the 64-bit virtual address space for GFX9, which is naturally reserved for kernel use. However, TBA (trap handler code) has problems to access addresses in the high virtual space. We have decided to set this to 8KB of the lower address space as a temporary fix, while investigate TBA address problem. It is very unlikely for user space to map memory at this low region.

2021-11-09drm/i915/hdmi: Turn DP++ TMDS output buffers back on in encoder->shutdown()Ville Syrjälä4-2/+17
Looks like our VBIOS/GOP generally fail to turn the DP dual mode adater TMDS output buffers back on after a reboot. This leads to a black screen after reboot if we turned the TMDS output buffers off prior to reboot. And if i915 decides to do a fastboot the black screen will persist even after i915 takes over. Apparently this has been a problem ever since commit b2ccb822d376 ("drm/i915: Enable/disable TMDS output buffers in DP++ adaptor as needed") if one rebooted while the display was turned off. And things became worse with commit fe0f1e3bfdfe ("drm/i915: Shut down displays gracefully on reboot") since now we always turn the display off before a reboot. This was reported on a RKL, but I confirmed the same behaviour on my SNB as well. So looks pretty universal. Let's fix this by explicitly turning the TMDS output buffers back on in the encoder->shutdown() hook. Note that this gets called after irqs have been disabled, so the i2c communication with the DP dual mode adapter has to be performed via polling (which the gmbus code is perfectly happy to do for us). We also need a bit of care in handling DDI encoders which may or may not be set up for HDMI output. Specifically ddc_pin will not be populated for a DP only DDI encoder, in which case we don't want to call intel_gmbus_get_adapter(). We can handle that by simply doing the dual mode adapter type check before calling intel_gmbus_get_adapter().
