When enabling ITS NUMA support on D05, I got the boot log: [ 0.000000] SRAT: PXM 0 -> ITS 0 -> Node 0 [ 0.000000] SRAT: PXM 0 -> ITS 1 -> Node 0 [ 0.000000] SRAT: PXM 0 -> ITS 2 -> Node 0 [ 0.000000] SRAT: PXM 1 -> ITS 3 -> Node 1 [ 0.000000] SRAT: ITS affinity exceeding max count[4] This is wrong on D05 as we have 8 ITSs with 4 NUMA nodes. So dynamically alloc the memory needed instead of using its_srat_maps[MAX_NUMNODES], which count the number of ITS entry(ies) in SRAT and alloc its_srat_maps as needed, then build the mapping of numa node to ITS ID. Of course, its_srat_maps will be freed after ITS probing because we don't need that after boot. After doing this, I got what I wanted: [ 0.000000] SRAT: PXM 0 -> ITS 0 -> Node 0 [ 0.000000] SRAT: PXM 0 -> ITS 1 -> Node 0 [ 0.000000] SRAT: PXM 0 -> ITS 2 -> Node 0 [ 0.000000] SRAT: PXM 1 -> ITS 3 -> Node 1 [ 0.000000] SRAT: PXM 2 -> ITS 4 -> Node 2 [ 0.000000] SRAT: PXM 2 -> ITS 5 -> Node 2 [ 0.000000] SRAT: PXM 2 -> ITS 6 -> Node 2 [ 0.000000] SRAT: PXM 3 -> ITS 7 -> Node 3 Fixes: dbd2b8267233 ("irqchip/gic-v3-its: Add ACPI NUMA node mapping") Signed-off-by: Hanjun Guo <hanjun.guo@linaro.org> Reviewed-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Cc: Ganapatrao Kulkarni <ganapatrao.kulkarni@cavium.com> Cc: John Garry <john.garry@huawei.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
