I think page_flip ioctl need to realize a synchronous mechanism to control
fresh rate...!!!

FWIW, there was a quite long discussion / argument when the page flip
ioctl was designed, and at that time
I pointed out that there are hardware capable of pageflipping using the
fifo/pipe with optional VSYNC barriers, and that it is actually possible
to queue up a number of pageflips in the fif

It seems that nv04_graph_mthd_page_flip() was called from isr , and page_flip
ioctl only send a NV_SW_PAGE_FLIP pushbuffer bo to gem. If you don't want the
screen show garbage you must make sure not to change frontbuffer or backbuffer
in GPU when nv_set_crtc_base() is called, and not change

It's intentionally not implemented. The reason is that I wanted to
support non-vsync'ed vblank as well, and for vsync'ed blits we had to

Can anyone give a suggestion, is wait-vblank fully implemented in page_flip()
for nouveau drm driver?

Dear,
I use NVidia Geforce 7300GT graphics card in my PC, and Linux 3.1rc4 kernel
code, git drm 2.4.36.
When I run the vbltest program, it prints "60HZ" which indicated the
implementation of drmWaitVBlank() and drm_vblank_wait() is correct.
But when I run modetest with option " -v -s 12:
