It allows the kernel to warn loudly when an outdated DT is detected, and restore the possibility to change the affinity of an interrupt routed through the GPC. This of course can only be applied of v5 (v6 contains these changes), and is posted at Shawn's request. Thanks, M.

Unfortunately not, as imx_gpc_init() is only called if the above properties are satisfied (that's exactly the case we want to detect: if imx_gpc_init is called, we're already in a pretty good shape).

Ah, yes. I forgot that the way imx_gpc_init() is called has been changed. I just gave the patch a go with an old DTB, and found that the kernel stops booting before we can even see this fat warning (see log below). It seems detecting at .init_machine time is too late. I tried to move the code to the beginning of function imx6q_init_irq(), and found it works as expected.

OK, I'll respin something shortly (we need to cover all three imx6 variants separately, it seems). Thanks for testing, M. -- Jazz is not dead.

* [PATCH 2/2] ARM: imx6: Allow GPC interrupts affinity to be changed 2015-03-12 8:40 [PATCH 0/2] ARM: imx6: GPC updates after conversion to stacked domains Marc Zyngier 2015-03-12 8:40 ` [PATCH 1/2] ARM: imx6: Warn when an old DT is detected Marc Zyngier @ 2015-03-12 8:40 ` Marc Zyngier 1 sibling, 0 replies; 7+ messages in thread From: Marc Zyngier @ 2015-03-12 8:40 UTC (permalink / raw) To: linux-arm-kernel While converting the GPC code to a stacked irqchip, we lost the possibility to change the CPU affinity of an interrupt routed through the GPC. This patch restore the expected behaviour by forwarding the affinity setup to the underlying irqchip (GIC).
