From 926b5dfa6b8dc666ff398044af6906b156e1d949 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 16 Dec 2019 11:24:57 +0000 Subject: irqchip/gic-v3: Only provision redistributors that are enabled in ACPI We currently allocate redistributor region structures for individual redistributors when ACPI doesn't present us with compact MMIO regions covering multiple redistributors. It turns out that we allocate these structures even when the redistributor is flagged as disabled by ACPI. It works fine until someone actually tries to tarse one of these structures, and access the corresponding MMIO region. Instead, track the number of enabled redistributors, and only allocate what is required. This makes sure that there is no invalid data to misuse.

This still works well for the typical GICv4.1 implementation, where the new vPE table is shared between the ITSs and the RDs. To make it explicit, let us introduce allocate_vpe_l2_table() to make sure that the L2 tables are allocated on all v4.1 RDs. We're likely not need to allocate memory in it because the vPE table is shared and (L2 table is) already allocated at ITS level, except for the case where the ITS doesn't share anything (say SVPET == 0, practically unlikely but architecturally allowed). The implementation of allocate_vpe_l2_table() is mostly copied from its_alloc_table_entry().
