drm/i915/display: add intel_display_limits.h for key enums

2023-01-25T11:59:12Z

Move a handful of key enums to a new file intel_display_limits.h. These are the enum types, and the MAX/NUM enumerations within them, that are used in other headers. Otherwise, there's no common theme between them. Replace intel_display.h include with intel_display_limit.h where relevant, and add the intel_display.h include directly in the .c files where needed. Since intel_display.h is used almost everywhere in display/, include it from intel_display_types.h to avoid massive changes across the board. There are very few files that would need intel_display_types.h but not intel_display.h so this is neglible, and further cleanup between these headers can be left for the future. Overall this change drops the direct and indirect dependencies on intel_display.h from about 300 to about 100 compilation units, because we can drop the include from i915_drv.h.

drm/i915/gvt: make fb_decoder.h self-contained

2020-12-22T03:39:05Z

Add necessary #includes and forward declarations to make the header compile on its own. While at it, also remove a useless forward declaration.

drm/i915: make more headers self-contained

2019-11-08T10:16:13Z

The headers in the gem/selftests/, gt/selftests, gvt/, selftests/ directories have never been compile-tested, but it would be possible to make them self-contained. This commit only addresses missing and forward struct declarations.

drm/i915/gvt: Fix drm_format_mod value for vGPU plane

2018-08-30T04:56:33Z

Physical plane's tiling mode value is given directly as drm_format_mod for plane query, which is not correct fourcc code. Fix it by using correct intel tiling fourcc mod definition. Current qemu seems also doesn't correctly utilize drm_format_mod for plane object setting. Anyway this is required to fix the usage. v3: use DRM_FORMAT_MOD_LINEAR, fix comment v2: Fix missed old 'tiled' use for stride calculation Fixes: e546e281d33d ("drm/i915/gvt: Dmabuf support for GVT-g") Cc: Tina Zhang Cc: Gerd Hoffmann Cc: Colin Xu Reviewed-by: Colin Xu Signed-off-by: Zhenyu Wang

drm/i915/gvt: Add framebuffer decoder support

2017-12-04T03:24:33Z

This patch is to introduce the framebuffer decoder which can decode guest OS's framebuffer information, including primary, cursor and sprite plane. v16: - rebase to 4.14.0-rc6. v14: - refine pixel format table. (Zhenyu) v9: - move drm format change to a separate patch. (Xiaoguang) v8: - fix a bug in decoding primary plane. (Tina) v7: - refine framebuffer decoder code.
