# SPDX-License-Identifier: GPL-2.0 menu "DMA support" config SH_DMA bool "SuperH on-chip DMA controller (DMAC) support" depends on CPU_SH3 || CPU_SH4 default n config SH_DMA_IRQ_MULTI bool depends on SH_DMA default y if CPU_SUBTYPE_SH7750 || CPU_SUBTYPE_SH7751 || \ CPU_SUBTYPE_SH7750S || CPU_SUBTYPE_SH7750R || \ CPU_SUBTYPE_SH7751R || CPU_SUBTYPE_SH7091 || \ CPU_SUBTYPE_SH7763 || CPU_SUBTYPE_SH7780 || \ CPU_SUBTYPE_SH7785 || CPU_SUBTYPE_SH7760 config SH_DMA_API depends on SH_DMA bool "SuperH DMA API support" default n help SH_DMA_API always enabled DMA API of used SuperH. If you want to use DMA ENGINE, you must not enable this. Please enable DMA_ENGINE and SH_DMAE. config NR_ONCHIP_DMA_CHANNELS int depends on SH_DMA default "4" if CPU_SUBTYPE_SH7750 || CPU_SUBTYPE_SH7751 || \ CPU_SUBTYPE_SH7750S || CPU_SUBTYPE_SH7091 default "8" if CPU_SUBTYPE_SH7750R || CPU_SUBTYPE_SH7751R || \ CPU_SUBTYPE_SH7760 default "12" if CPU_SUBTYPE_SH7723 || CPU_SUBTYPE_SH7780 || \ CPU_SUBTYPE_SH7785 || CPU_SUBTYPE_SH7724 default "6" help This allows you to specify the number of channels that the on-chip DMAC supports. This will be 4 for SH7750/SH7751/Sh7750S/SH7091 and 8 for the SH7750R/SH7751R/SH7760, 12 for the SH7723/SH7780/SH7785/SH7724, default is 6. config SH_DMABRG bool "SH7760 DMABRG support" depends on CPU_SUBTYPE_SH7760 help The DMABRG does data transfers from main memory to Audio/USB units of the SH7760. Say Y if you want to use Audio/USB DMA on your SH7760 board. config PVR2_DMA tristate "PowerVR 2 DMAC support" depends on SH_DREAMCAST && SH_DMA help Selecting this will enable support for the PVR2 DMA controller. As this chains off of the on-chip DMAC, that must also be enabled by default. This is primarily used by the pvr2fb framebuffer driver for certain optimizations, but is not necessary for functionality. If in doubt, say N. config G2_DMA tristate "G2 Bus DMA support" depends on SH_DREAMCAST && SH_DMA_API help This enables support for the DMA controller for the Dreamcast's G2 bus. Drivers that want this will generally enable this on their own. If in doubt, say N. endmenu
