support Iris driver #594

Closed tpalli closed 5 years ago

tpalli commented 5 years ago

Patch forces compositor to disable sync if this was explicitly wanted during build since setting property 'board.disable.explicit.sync' does not work as expected.

Hi Tapani,

Why Iris can't support explict sync? Android framework is using explict fence to sync

It does not seem to work yet (and is currently disabled in driver by not exposing PIPE_CAP_NATIVE_FENCE_FD capability) , I'm assuming this to be a bug in Iris driver, I've tried to fix things but haven't found a cure so far.

Note I'm fine not merging this yet. I'm just basically trying to reduce the amount of diff I have for making Iris to work so that it would be easier to do testing and development as I have changes in multiple repos.

OK. I think best way it to fix in Iris i915 so explicit fence can be supported

OK that is fine. I've pushed small changes to minigbm, libdrm (external) and selinux. There are additional changes required in mesa, mixins and also hwcomposer (these). Anyone wanting to test Iris, please contact me and I can help if having problems.
