I'm sure I don't need to tell you that fb_helper's locking is a mess. That being said; fb_helper's locking mess can seriously complicate the runtime suspend/resume operations of drivers because it can invoke atomic commits and connector probing from anywhere that calls drm_fb_helper_hotplug_event(). Since most drivers use drm_fb_helper_output_poll_changed() as their

After its cleanup, struct nouveau_framebuffer is only a wrapper around struct drm_framebuffer. Use the latter directly.

(Re-sending to list rather than just to James) Is this format modifier information not stored, or otherwise worth storing, directly in the nouveau_bo object associated with the framebuffer? I'm not particularly knowledgeable on the topic, but there already seem to exist some fields with very similar names in nouveau_bo. Best, Roy On 06/02/2020 15:17, James Jones wrote: > Note I'm

I've sent out a v4 version of the format modifier patches which avoid caching values in the nouveau_framebuffer struct. It will have a few trivial conflicts with your series, but should make them structurally compatible. I'm fine with either v3 or v4 of my series personally, but if these cleanup patches are taken, only v4 will work. Thanks, -James On 2/6/20 8:45 AM, James Jones

So ... for Vulkan, the API requires allocating VA before declaring what goes into that VA (e.g. an image or data). I believe our plan for that was to move all this into userspace, which would allocate VA and then just tell the kernel "make VA range X have memtype Y". At that point, nouveau_bo would be left mainly for compat as well as for things like framebuffer backing. James, in what

Uh, loaded statement :-) Especially since we've just reworked all the fbdev locking to untangle it from drm_modeset locking. What's still a mess about it? It's documented, and very clearly wrapped around all the drm_modeset locks. If

Yes, that's certainly viable. If that's the general preference in direction, I'll rework that patches to do so.

The format modifiers, when present, override the equivalent field in the BO. Right now, that's probably not particularly useful. However, as nouveau interfaces evolve towards the HW capabilities and add support for newer graphics APIs, saying an entire BO has a singular layout becomes less meaningful, so I suspect those fields will be effectively deprecated in favor of the

The vma field of struct nouveau_framebuffer is a special field for the the accelerated fbdev console. Hence there's at most one single instance for the active console. Moving it into struct nouveau_fbdev makes struct nouveau_framebuffer slightly smaller and brings it closer to struct drm_framebuffer. Signed-off-by: Thomas Zimmermann <tzimmermann at suse.de> ---
