drm/i915: add io_size plumbing

2022-02-28T08:47:27Z

With small LMEM-BAR we need to be able to differentiate between the total size of LMEM, and how much of it is CPU mappable. The end goal is to be able to utilize the entire range, even if part of is it not CPU accessible. v2: also update intelfb_create Signed-off-by: Matthew Auld Cc: Thomas Hellström Reviewed-by: Thomas Hellström Acked-by: Nirmoy Das Link: https://patchwork.freedesktop.org/patch/msgid/20220225145502.331818-1-matthew.auld@intel.com

drm/i915/fbdev: hide struct intel_fbdev in intel_fbdev.c

2022-02-17T08:05:09Z

As all access to struct intel_fbdev guts is nicely stowed away in intel_fbdev.c, we can hide the struct definition there too. Reviewed-by: Ville Syrjälä Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20220215122957.2755529-2-jani.nikula@intel.com

GGTT is currently available both through i915->ggtt and gt->ggtt, and we eventually want to get rid of the i915->ggtt one. Use to_gt() for all i915->ggtt accesses to help with the future refactoring.

drm/i915/display: Drop unnecessary frontbuffer flushes

2021-09-30T22:04:44Z

This unnecessary flushes are hurting power-savings are it causes features like PSR, FBC and DRRS to disable it self to handle frontbuffer rendering, below some explanation of why each removed call is not necessary. The flush in intel_prepare_plane_fb() is not required as framebuffer will be flipped and power-saving features do the proper flip handling in hardware. intel_find_initial_plane_obj() flush is not required because it is only executed during driver load and at this point the power-saving features are not even enabled. And the last one intelfb_create(), is also not required as at this point the fbdev was just allocated, userspace will draw on it what will trigger frontbuffer invalidates and flushes later on.

drm/i915: Clean up intel_fbdev_init_bios() a bit

2021-06-24T19:03:58Z

Sort out the mess with the local variables in intel_fbdev_init_bios(). Get rid of all aliasing pointers, use standard naming/types, and introduce a few more locals in the loops to avoid the hard to read long struct walks. While at we also polish the debugs a bit to use the canonical [CRTC:%d:%s] style.
