drm/i915/fb: convert intel_framebuffer_create() to struct drm_gem_object

2024-09-19T13:37:06Z

Prefer the driver agnostic struct drm_gem_object over i915 specific struct drm_i915_gem_object. Move the declaration to the right place while at it.

drm/i915/fbdev: convert intel_fbdev.c to struct drm_gem_object

2024-09-19T13:19:39Z

Prefer the driver agnostic struct drm_gem_object over i915 specific struct drm_i915_gem_object. Add new intel_bo_* functions as needed.

drm/i915: Change intel_fbdev_fb_alloc() return type

2024-05-13T16:22:48Z

Change intel_fbdev_fb_alloc() to return struct intel_fb instead of struct drm_framebuffer.

drm/i915/fbdev: Fix smem_start for LMEMBAR stolen objects

2024-02-07T00:01:43Z

The "io" address of an object is its dma address minus the region.start. Subtract the latter to make smem_start correct. The current code happens to work for genuine LMEM objects as LMEM region.start==0, but for LMEMBAR stolen objects region.start!=0. TODO: perhaps just set smem_start=0 always as our .fb_mmap() implementation no longer depends on it? Need to double check it's not needed for anything else...

drm/i915: Use struct resource for memory region IO as well

2024-02-06T23:58:40Z

mem->region is a struct resource, but mem->io_start and mem->io_size are not for whatever reason. Let's unify this and convert the io stuff into a struct resource as well. Should make life a little less annoying when you don't have juggle between two different approaches all the time. Mostly done using cocci (with manual tweaks at all the places where we mutate io_size by hand): @@ struct intel_memory_region *M; expression START, SIZE; @@ - M->io_start = START; - M->io_size = SIZE; + M->io = DEFINE_RES_MEM(START, SIZE); @@ struct intel_memory_region *M; @@ - M->io_start + M->io.start @@ struct intel_memory_region M; @@ - M.io_start + M.io.start @@ expression M; @@ - M->io_size + resource_size(&M->io) @@ expression M; @@ - M.io_size + resource_size(&M.io) Reviewed-by: Andrzej Hajda Acked-by: Nirmoy Das Tested-by: Paz Zcharya Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20240202224340.30647-2-ville.syrjala@linux.intel.com
