Hi Andrey,

Thank you for the patch.

The DRM core's atomic page flip helper doesn't get/put vblank. Have you 
double-checked that removing them isn't a problem ?

This patch makes the amdgpu DM code use the page_flip_target hook.
drm_mode_page_flip_ioctl calls drm_crtc_vblank_get before the
page_flip_target hook.

You're right though that the fact that drm_atomic_helper_page_flip
doesn't call drm_crtc_vblank_get is a bit alarming. From the
DRM_IOCTL_MODE_PAGE_FLIP POV, drm_crtc_vblank_get must be called when
userspace calls the ioctl (either by drm_mode_page_flip_ioctl or the
page_flip hook implementation), and drm_crtc_vblank_put must be called
when the flip completes and the event is sent to userspace. How is this
supposed to be handled with atomic?

Andrey, did you check via code audit and/or testing that the vblank
reference count is still balanced after this change?

Yeah, such whitespace-only changes should be dropped.

First let me ask you - why we have to enable vlbank as part of pflip, 
I understand why it has to be enbbled in WAIT_FOR_VBLANK IOCTL 
but not sure about PFLIP IOCTL. 

IMHO in atomic as before in legacy page_flip, it's up to the  driver 
implementation in atomic_commit hook   to manage vblank ISR
on,off.> 
> Andrey, did you check via code audit and/or testing that the vblank
> reference count is still balanced after this change?
> With the page_flip_target yes, if I switch back to page_flip hook then 
vblank ISR never gets enabled on FLIP IPCTL and then I see warning in DAL's
pflip done IRQ handler from vblank_put which is obvious, which BTW
didn't impact the flips, I still was able to run glxgears in vsync mode.
