Palmer Dabbelt 3aefb2ee5b riscv: implement Zicbom-based CMO instructions + the t-head variant ... This series is based on the alternatives changes done in my svpbmt series and thus also depends on Atish's isa-extension parsing series. It implements using the cache-management instructions from the Zicbom- extension to handle cache flush, etc actions on platforms needing them. SoCs using cpu cores from T-Head like the Allwinne D1 implement a different set of cache instructions. But while they are different, instructions they provide the same functionality, so a variant can easly hook into the existing alternatives mechanism on those. [Palmer: Some minor fixups, including a RISCV_ISA_ZICBOM dependency on MMU that's probably not strictly necessary. The Zicbom support will trip up sparse for users that have new toolchains, I just sent a patch.] Link: https://lore.kernel.org/all/20220706231536.2041855-1-heiko@sntech.de/ Link: https://lore.kernel.org/linux-sparse/20220811033138.20676-1-palmer@rivosinc.com/T/#u * palmer/riscv-zicbom: riscv: implement cache-management errata for T-Head SoCs riscv: Add support for non-coherent devices using zicbom extension dt-bindings: riscv: document cbom-block-size of: also handle dma-noncoherent in of_dma_is_coherent()		2022-08-10 20:49:32 -07:00
