[PATCH v3 0/3] arm64: dts: hi3798cv200: fix GICR size, add cache info, maintenance irq and GICH, GICV spaces

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patchset fixes some warnings reported by the kernel during boot.

The cache size info is from Processor_Datasheet_v2XX.pdf [1], Section
2.2.1 Master Processor.

The cache line size and the set-associative info are from Cortex-A53
Documentation [2].

>From the doc, it can be concluded that L1 i-cache is 4-way assoc, L1
d-cache is 2-way assoc and L2 cache is 16-way assoc. Calculate the dts
props accordingly.

Also, to use KVM's VGIC code, GICH, GICV registers spaces and maintenance
IRQ are added to the dts with verification.
