The psp supplies the link type in the upper 2 bits of the psp xgmi node information num_hops field. With a new link type, Aldebaran has these bits set to a non-zero value (1 = xGMI3) so the KFD topology will report the incorrect IO link weights without proper masking. The actual number of hops is located in the 3 least significant bits of this field so mask if off accordingly before passing it to the KFD.

Leaving this at a close-to-maximum register value 0xFFF0 means it takes very long for the MDSS to generate a software vsync interrupt when the hardware TE interrupt doesn't arrive. Configuring this to double the vtotal (like some downstream kernels) leads to a frame to take at most twice before the vsync signal, until hardware TE comes up.
In this case the hardware interrupt responsible for providing this signal - "disp-te" gpio - is not hooked up to the mdp5 vsync/pp logic at all. This solves severe panel update issues observed on at least the Xperia Loire and Tone series, until said gpio is properly hooked up to an irq.

[ Upstream commit 377569f82ea8228c421cef4da33e056a900b58ca ]
Neither vtotal nor drm_mode_vrefresh contain a value that is premultiplied by 100 making the x100 variable name incorrect and resulting in vclks_line to become 100 times larger than it is supposed to be. The hardware counts 100 clockticks too many before tearcheck, leading to severe panel issues on at least the Sony Xperia lineup.
This is likely an artifact from the original MDSS DSI panel driver where the calculation [1] corrected for a premultiplied reference framerate by 100 [2]. It does not appear that the above values were ever premultiplied in the history of the DRM MDP5 driver.
With this change applied the value written to the SYNC_CONFIG_VSYNC register is now identical to downstream kernels.

clang points out that the %hu format string does not match the type of the variables here:
drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.c:263:7: warning: format specifies type 'unsigned short' but the argument has type 'unsigned int' [-Wformat] version_major, version_minor); ^~~~~~~~~~~~~ include/drm/drm_print.h:498:19: note: expanded from macro 'DRM_ERROR' __drm_err(fmt, ##__VA_ARGS__) ~~~ ^~~~~~~~~~~
Change it to a regular %u, the same way a previous patch did for another instance of the same warning.
