| bool "Meson cpu ddr tool" |
| depends on AMLOGIC_DRIVER |
| default n |
| help |
| This config add some debug tools for DDR, including test ddr |
| bandwidth, ddr window and other configs. |
| For more information. |
| Please see folllowing configs |
| |
| config AMLOGIC_DDR_WINDOW_TOOL |
| tristate "Meson ddr window tool" |
| default m |
| depends on AMLOGIC_DDR_TOOL |
| help |
| This config enables test for ddr window. |
| This driver acts as a kernel agent which set different ddr window |
| register value from user space, user space can generate large ddr |
| loading to test each value are stable. |
| |
| config AMLOGIC_DDR_BANDWIDTH |
| bool "Meson ddr bandwidth" |
| default n |
| depends on AMLOGIC_DDR_TOOL |
| help |
| This config enables ddr bandwidth measure. |
| If open it, this driver will export interface to get ddr total |
| bandwidth, it can be used for ddr DVFS/devfreq system. |
| |
| config AMLOGIC_DMC_MONITOR |
| bool "Amlogic dmc monitor" |
| depends on AMLOGIC_DDR_TOOL |
| default y |
| help |
| DMC monitor for hardware connected to DMC master. Using it can |
| set up an address range and assign R/W permission for each |
| hardware. If hardware violated R/W permission, then interrupt |
| will generated and can help to debug memory pollution. |
