uint32_t w, h, d;
+};
There was a similar case (multiple variables declared on a single line) in drm core that caused confusion and we broke the 32bit compat. I thought I mention it - not advocating for/against the above declaration.
probably should put some newlines alright,
+struct drm_virtgpu_3d_transfer_to_host {
uint32_t bo_handle;
struct drm_virtgpu_3d_box box;
uint32_t level;
uint32_t offset;
+};
+struct drm_virtgpu_3d_transfer_from_host {
uint32_t bo_handle;
struct drm_virtgpu_3d_box box;
uint32_t level;
uint32_t offset;
+};
Afaics these seems to be used by the ioctls. If so the current declarations are not 32bit compat safe. Things will also go badly if you consider expanding struct drm_virtgpu_3d_box in the distant future. A u32 pad after bo_handle and a 'pointer' to struct
I'm curious what you think we can add to a 3d box.
So this one is fine, no need to align it either I don't think, though I should confirm that.
Maybe for safety we can pull the other uint32_t above the box.
