I should clarify that you can pre-configure the colorkey before turning on the 
sprite plane(s). So unless you really need to change the colorkey while the 
sprite plane(s) are already enabled you may not even need an atomic api for 
this.

2019-04-10 Thread Jim Zhang
Ville:

Yes, if this patch is needed by kernel 3.10.61,  please get somebody to review 
it.  What do I need do to speed up the review process?
Please generate a patch against kernel 3.10.61 if possible.

Thanks,

Jim

If I go with pre-configured colorkey, do I need port your kernel patch to i915 
driver at kernel 3.10.61 ?

RE: [Intel-gfx] colorkey support for intel i915 gpu driver

2019-04-10 Thread Jim Zhang
What about if I disable interrupt when changing the colorkey?  This will solve 
the atomic issue.  I think we only change colorkey or enable/disable colorkey 
once a while. If disabling interrupt work, I will disable interrupt and change 
colorkey. That performance affection could be acceptable

Thanks

Not atomically with other updates.

Once I pre-configure the colorkey, am I able to enable and disable it? If 
colorkey can be enabled/disabled after that might meet my requirement

I should clarify that you can pre-configure the colorkey before turning on the 
sprite plane(s). So unless you really need to change the colorkey while the 
sprite plane(s) are already enabled you may not even need an atomic api for

https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/tree/src/sna/sna_video_sprite.c
is the only userspace code we have that uses the colorkey.

I should clarify that you can pre-configure the colorkey before
turning on the sprite plane(s). So unless you really need to change
the colorkey while the sprite plane(s) are already enabled you may
not even need an atomic api for this.
