Use of abs() wrongly wrapped diff_ns to 32 bit, which gives a 1/4000
probability of a missed vblank increment at each vblank irq reenable
if the kms driver doesn't support high precision vblank timestamping.
Not a big deal in practice, but let's make it nice.

Documentation/atomic_ops.txt tells us that there are memory
barriers optimized for atomic_inc and other atomic_t ops.
Use these instead of smp_wmb(), and also to make the required
memory barriers around vblank counter increments more explicit.

It's not abusing it but extending the interface in a

That the vblank timestamp needs to be an accurate measurement of a

Hi,
testing on "simulated" pre-DCE4 radeon hw (via setting the module
parameter radeon.use_pflipirq=0 to avoid use of pflip irqs) showed
we need some adjustments on top of Michel's page_flip_target patches
on these old asics.

Essentially disabling the ability to flip anywhere in

the actual flip programming until after vblank on pre-AVIVO.

Hi Michel,
sorry for the super-late reply, i was just catching up with all the
mails and discussions, starting in June, leading to this patch set.
Looks all pretty good.
I'll look at this radeon patch and 2/6 for amdgpu later this week when i
have a fresh brain and enough "obsessive

Wrt. having a new pageflip parameter struct, i wonder if it wouldn't
make sense to then already prepare some space in it for specifying an
absolute target time, e.g., in u64 microseconds? Or make this part of

Hi,
i spent some time playing with DRI3/Present + PRIME for testing
how well it works for Optimus/Enduro style setups wrt. page flipping
on the current kernel/mesa/xorg. I want page flipping, because

During the pinning into GTT, we skip the actual data move
from VRAM to GTT to avoid a needless bo copy of stale
image data.

Btw. i'll be offline for the next few hours, just wanted to get this out
now.

Prime render offload, and with the Tonga standalone as
primary gpu.
v2: Add a wait for all shared fences before prime export,
as suggested by Christian Koenig.

v5: - Drop lret, instead use int ret -> long ret, as proposed
by Christian.

The following patch implements precise vblank timestamping
for RaspberryPi's VC4, at least for standard progressive
scan display modes.
It has been tested on the HDMI output with half a dozen different
video modes using special hardware measurement equipment to compare
generated time stamps
, and hope for the best.
Measurement shows the generated timestamps to be rather precise,
and at least never off more than 1 vblank duration worst-case.
Limitations: Doesn't work well yet for interlaced video modes,
therefore disabled in interlaced mode for now.

ppen. However that glitch would hopefully be hidden by the blanking of
the crtc during modeset. A small fix to power management makes sure to
check for this and prevent unbalanced vblank reference counts due to
mismatched drm_vblank_get/put.
