Subject: RE: [PATCH 6/7] arm64: tegra: Add DT node for T194 SMMU
Date: Fri, 30 Aug 2019 18:35:23 +0000	[thread overview]
Message-ID: <BYAPR12MB2710B0F6F5630BF0BE7B4663B3BD0@BYAPR12MB2710.namprd12.prod.outlook.com> (raw)

>The number of global interrupts has never been related to the number of context interrupts :/

Yeah,  They are not related. I was trying to use minimum irq entries in the DT node as they both would achieve the same functionality.

>Clearly you have one combined interrupt output per SMMU - describing those as one global interrupt and the first two context bank interrupts respectively makes far less sense than calling them 3 global interrupts, not least because the latter is strictly true.

Will update to 3 in next patch to make it better for readability.
