The GICv3 documentation is extremely confusing, as it talks about the number of priorities represented by the ICH_APxRn_EL2 registers, while it should really talk about the number of preemption levels. This leads to a bug where we may access undefined ICH_APxRn_EL2 registers, since PREbits is allowed to be smaller than PRIbits. Thankfully, nobody seem to have taken this path so far... The fix is to use ICH_VTR_EL2.PREbits instead. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Reviewed-by: Christoffer Dall <cdall@linaro.org> Signed-off-by: Christoffer Dall <cdall@linaro.org> |
