I'm planning to do some verification on our GIC-v4.1 implement. I would like some information about linux GIC-v4.1 driver. When will linux support GIC-v4.1 or what's the plan on developing GIC-v4.1 driver? Thanks, Nianyao. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply [flat|nested] 4+ messages in thread

There is some code, even, just not quite in a usable state yet. I'll try to push something out once I get a chance.

FWIW, I've pushed out a branch containing the current state of this work at [1]. It doesn't really work at the moment (Doorbells and SGIs are unreliable), but hopefully that will give you an idea of what is going on. Being a work in progress, it is unstable, subject to being changed, rebased and deleted without warning. Thanks, M.

I will check on this code first. If have any doubt, I will 'noise' you again ;-) Thanks in advance, Shaokun > Being a work in progress, it is unstable, subject to being changed, > rebased and deleted without warning. > > Thanks, > > M. > > [1] > https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git/log/?h=irq/gic-v4.1-devel > _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply [flat|nested] 4+ messages in thread
