Revision ba56bc3a0786992755e6804fbcbdc60ef6cfc24c authored by Ard Biesheuvel on 01 June 2018, 15:06:28 UTC, committed by Marc Zyngier on 21 June 2018, 08:14:44 UTC
When booting a 64 KB pages kernel on a ACPI GICv3 system that implements support for v2 emulation, the following warning is produced GICV size 0x2000 not a multiple of page size 0x10000 and support for v2 emulation is disabled, preventing GICv2 VMs from being able to run on such hosts. The reason is that vgic_v3_probe() performs a sanity check on the size of the window (it should be a multiple of the page size), while the ACPI MADT parsing code hardcodes the size of the window to 8 KB. This makes sense, considering that ACPI does not bother to describe the size in the first place, under the assumption that platforms implementing ACPI will follow the architecture and not put anything else in the same 64 KB window. So let's just drop the sanity check altogether, and assume that the window is at least 64 KB in size.
