drm-misc-next for v6.1: UAPI Changes: Cross-subsystem Changes: - DMA-buf: documentation updates. - Assorted small fixes to vga16fb - Fix fbdev drivers to use the aperture helpers. - Make removal of conflicting drivers work correctly without fbdev enabled. Core Changes: - bridge, scheduler, dp-mst: Assorted small fixes. - Add more format helpers to fourcc, and use it to replace the cpp usage. - Add DRM_FORMAT_Cxx, DRM_FORMAT_Rxx (single channel), and DRM_FORMAT_Dxx ("darkness", inverted single channel) - Add packed AYUV8888 and XYUV8888 formats. - Assorted documentation updates. - Rename ttm_bo_init to ttm_bo_init_validate. - Allow TTM bo's to exist without backing store. - Convert drm selftests to kunit. - Add managed init functions for (panel) bridge, crtc, encoder and connector. - Fix endianness handling in various format conversion helpers. - Make tests pass on big-endian platforms, and add test for rgb888 -> rgb565 - Move DRM_PLANE_HELPER_NO_SCALING to atomic helpers and rename, so drm_plane_helper is no longer needed in most drivers. - Use idr_init_base instead of idr_init. - Rename FB and GEM CMA helpers to DMA helpers. - Rework XRGB8888 related conversion helpers, and add drm_fb_blit() that takes a iosys_map. Make drm_fb_memcpy take an iosys_map too. - Move edid luminance calculation to core, and use it in i915. Driver Changes: - bridge/{adv7511,ti-sn65dsi86,parade-ps8640}, panel/{simple,nt35510,tc358767}, nouveau, sun4i, mipi-dsi, mgag200, bochs, arm, komeda, vmwgfx, pl111: Assorted small fixes and doc updates. - vc4: Rework hdmi power up, and depend on PM. - panel/simple: Add Samsung LTL101AL01. - ingenic: Add JZ4760(B) support, avoid a modeset when sharpness property is unchanged, and use the new PM ops. - Revert some amdgpu commits that cause garbaged graphics when starting X, and reapply them with the real problem fixed. - Completely rework vc4 init to use managed helpers. - Rename via_drv to via_dri1, and move all stuff there only used by the dri1 implementation in preperation for atomic modeset. - Use regmap bulk write in ssd130x. - Power sequence and clock updates to it6505. - Split panel-sitrox-st7701 init sequence and rework mode programming code. - virtio: Improve error and edge conditions handling, and convert to use managed helpers. - Add Samsung LTL101AL01, B120XAN01.0, R140NWF5 RH, DMT028VGHMCMI-1A T, panels. - Add generic fbdev support to komeda. - Split mgag200 modeset handling to make it more model-specific. - Convert simpledrm to use atomic helpers. - Improve udl suspend/disconnect handling.

drm/amdgpu: Only disable prefer_shadow on hawaii

2022-08-10T19:41:23+00:00

We changed it for all asics due to a hibernation regression on hawaii, but the workaround breaks suspend on a polaris12. Just disable it for hawaii.

2022-07-26T16:42:00+00:00

Rename DRM_PLANE_HELPER_NO_SCALING to DRM_PLANE_NO_SCALING. The constant is not really a helper, but rather a characteristic of the plane itself.

This reverts commit 4046afcebfc3c8c0dd5666c2671b2c192b344f78. No need to support modifier in virtual kms, otherwise, in SRIOV mode, when lanuching X server, set crtc will fail due to mismatch between primary plane modifier and framebuffer modifier.
