Wed, 04 Oct 2023 15:08:56 +0000

soc: renesas: Make ARCH_R9A07G043 (riscv version) depend on NONPORTABLEDrew found "CONFIG_DMA_GLOBAL_POOL=y causes ADMA buffer alloc to fail"the log looks like: mmc0: Unable to allocate ADMA buffers - falling back to standard DMAThe logic is: generic riscv defconfig selects ARCH_RENESAS thenARCH_R9A07G043 which selects DMA_GLOBAL_POOL, which assumes allnon-dma-coherent riscv platforms have a dma global pool, this assumptionseems not correct. And I believe DMA_GLOBAL_POOL should not beselected by ARCH_SOCFAMILIY, instead, only ARCH under some specificconditions can select it globaly, for example NOMMU ARM and so on,because it's designed for special cases such as "nommu cases wherenon-cacheable memory lives in a fixed place in the physical addressmap" as pointed out by Robin.Fix the issue by making ARCH_R9A07G043 (riscv version) depend onNONPORTABLE, thus generic defconfig won't select ARCH_R9A07G043 bydefault. And even for random config case, there will be less debugeffort once we see NONPORTABLE is enabled.Reported-by: Drew Fustini Closes: https://lore.kernel.org/linux-riscv/ZRuamJuShOnvP1pr@x1/Fixes: 484861e09f3e ("soc: renesas: Kconfig: Select the required configs for RZ/Five SoC")Signed-off-by: Jisheng Zhang Reviewed-by: Robin Murphy Reviewed-by: Lad Prabhakar Reviewed-by: Geert Uytterhoeven Tested-by: Drew Fustini Link: https://lore.kernel.org/r/20231004150856.2540-1-jszhang@kernel.orgSigned-off-by: Geert Uytterhoeven List of files: /linux-6.15/drivers/soc/renesas/Kconfig
