drm/amd/display: fix issue where 252-255 values are clipped

2019-10-07T16:58:53Z

[ Upstream commit 1cbcfc975164f397b449efb17f59d81a703090db ] [Why] When endpoint is at the boundary of a region, such as at 2^0=1 we find that the last segment has a sharp slope and some points are clipped at the top. [How] If end point is 1, which is exactly at the 2^0 region boundary, we need to program an additional region beyond this point.

[ Upstream commit 67fd6c0d2de8e51e84ff3fa6e68bbd524f823e49 ] [Why] Driver will create 0, 1, and 2 ddc engines for RV2, but some platforms used 0, 1, and 3. [How] Still allocate 4 ddc engines for RV2.

drm/amd/display: put back front end initialization sequence

2019-08-16T08:11:01Z

[ Upstream commit feb7eb522e0a7a22c1e60d386bd3c3bfa1d5e4f7 ] [Why] Seamless boot optimization removed proper front end power off sequence. In driver disable enable case, this causes driver to power gate hubp and dpp while there is still memory fetching going on, this can cause invalid memory requests to be generated which will hang data fabric.

drm/amd/display: Clock does not lower in Updateplanes

2019-08-16T08:11:00Z

[ Upstream commit 492d9ec244923420af96db6b69ad7d575859aa92 ] [why] We reset the optimized_required in atomic_plane_disable flag immediately after it is set in atomic_plane_disconnect, causing us to never have flag set during next flip in UpdatePlanes. [how] Optimize directly after each time plane is removed. Signed-off-by: Murton Liu Reviewed-by: Tony Cheng Acked-by: Leo Li Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amd/display: Add hubp_init entry to hubp vtable

2019-04-29T19:59:06Z

Different HW will need to init HUBP differently. For now, add a vtable entry, and hook a NO-OP for DCN1. In addition, future HW will need to access the HUBPREQ_DEBUG register for hubp_init. Add it to the reg list. Signed-off-by: Charlene Liu Reviewed-by: Jun Lei Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: Add power down display on boot flag

2019-04-29T19:58:53Z

[Why] Due to the generic introduction of seamless boot, the display is no longer blanked upon boot. However, this causes corruption on some systems that does not lock the memory in the non-secure boot case, resulting in brief corruption on boot due to garbage being written into the frame buffer. [How] Add a flag, read during DC init, to determine whether display should be blanked on boot. Default to true.

* Replace certain register writes with register sets that overwrites the the entire register, instead of only a field within the register. * Add program_watermarks() entry to hubbub vtable.
