As promised in the basic wide planes support ([1]) here comes a series supporting 2*max_linewidth for all the planes.
Note: Unlike v1 and v2 this series finally includes support for additional planes - having more planes than the number of SSPP blocks. Note: this iteration features handling of rotation and reflection of the wide plane. However rot90 is still not tested: it is enabled on sc7280 and it only supports UBWC (tiled) framebuffers, it was quite low on my priority list. [1] https://patchwork.freedesktop.org/series/99909/ Changes since v2: - Dropped the encoder-related parts, leave all resource allocation as is (Abhinav) - Significantly reworked the SSPP allocation code - Added debugging code to dump RM state in dri/N/state Changes since v1: - Fixed build error due to me missing one of fixups, it was left uncommitted. - Implementated proper handling of wide plane rotation & reflection.
