Remove drm_mode_config_fb, I don't see the point of it. To make it clear that it's ok to use plane->fb directly, move up drm_drv_uses_atomic_modeset so the code is skipped for atomic drivers that require plane_state->fb. Signed-off-by:

The current drm_fb_helper_sys helpers referenced in fb_ops assume that the video memory is in system RAM. This is not the case for sparc which uses direct physical memory accesses for IO memory and causes the bochs_drm module to panic immediately upon startup as it tries to initialise the framebuffer. Switching fb_ops over to use the drm_fb_helper_cfb helpers ensures that the correct accesses are used on sparc, fixing the panic and allowing the bochs_drm module to function under qemu-system-sparc64.

In some cases, like cursor updates, it is interesting to update the plane in an asynchronous fashion to avoid big delays. The current queued update could be still waiting for a fence to signal and thus block any subsequent update until its scan out. In cases like this if we update the cursor synchronously through the atomic API it will cause significant delays that would even be noticed by the final user. This patch creates a fast path to jump ahead the current queued state and do single planes updates without going through all atomic steps in drm_atomic_helper_commit(). We take this path for legacy cursor updates. For now only single plane updates are supported, but we plan to support multiple planes updates and async PageFlips through this interface as well in the near future. v6: - move check code to drm_atomic_helper.c (Daniel Vetter) v5: - improve comments (Eric Anholt) v4: - fix state->crtc NULL check (Archit Taneja) v3: - fix iteration on the wrong crtc state - put back code to forbid updates if there is a queued update for the same plane (Ville Syrjälä) - move size checks back to drivers (Ville Syrjälä) - move ASYNC_UPDATE flag addition to its own patch (Ville Syrjälä) v2: - allow updates even if there is a queued update for the same plane. - fixes on the documentation (Emil Velikov) - unconditionally call ->atomic_async_update (Emil Velikov) - check for ->atomic_async_update earlier (Daniel Vetter) - make ->atomic_async_check() the last step (Daniel Vetter) - add ASYNC_UPDATE flag (Eric Anholt) - update state in core after ->atomic_async_update (Eric Anholt) - update docs (Eric Anholt) Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Rob Clark <robdclark@gmail.com> Cc: Eric Anholt <eric@anholt.net> Signed-off-by:Gustavo Padovan <gustavo.padovan@collabora.com> Reviewed-by: Archit Taneja <architt@codeaurora.org> (v5) Acked-by: Eric Anholt <eric@anholt.net> (v5) Reviewed-by:

The old state is useful for drivers that need to perform operations at enable time that depend on the transition between the old and new states. While at it, rename the operation to .atomic_enable() to be consistent with .atomic_disable(), as the .enable() operation is used by atomic helpers only. Signed-off-by:

There's no reason for drivers to call this, and all the ones I've removed looked very fishy: - Proper quiescenting of the vblank machinery should be done by calling drm_crtc_vblank_off(), which is best done by shutting down the entire display engine with drm_atomic_helper_shutdown. - Releasing of allocated memory is done by the core already, it calls drm_vblank_cleanup as a fallback. - drm_vblank_cleanup also has checks for drivers which forget to clean up vblank interrupts. This essentially reverts commit e77cef9c Author: Jerome Glisse <jglisse@redhat.com> Date: Thu Jan 7 15:39:13 2010 +0100 drm: Avoid calling vblank function is vblank wasn't initialized which was done to fix a bug in radeon code with msi interrupts: commit 003e69f9 Author: Jerome Glisse <jglisse@redhat.com> Date: Thu Jan 7 15:39:14 2010 +0100 drm/radeon/kms: Don't try to enable IRQ if we have no handler installed Afaict from digging around in old code, this was needed to avoid blowing up in the ums fallback, and has stopped serving it's purpose long ago - if irq init fails, the driver fails to load, and there's really no way to blow up anymore. Long story short, this was most likely a small ums compat/fallback hack that became a thing of it's own and got cargo-cult duplicated all over the drm codebase for essentially no gain at all. v2: Mention that for drivers with a ->release callback cleanup is handled by drm_dev_fini() (Thierry).

Problem : While running IGT kms_atomic_transition test suite i encountered a hang in drmHandleEvent immediately following an atomic_commit. After dumping the atomic state I relized that in this case there was not even one CRTC attached to the state and only disabled planes. This probably due to a commit which hadn't changed any property which would require attaching crtc state. This means drmHandleEvent will never wake up from read since without CRTC in atomic state the event fd will not be signaled. Fix: Protect against this issue by failing atomic_commit early in drm_mode_atomic_commit where such probelm can be identified. v2: Fix typos and extra newlines.

The crtc->commit_lock only protects commit_list and commit_entry. If we chase the pointer from the drm_atomic_state update structure, then we don't need any locks (since we hold a reference already).
