CONFIG_BRCMSTB_DPFE: Broadcom STB DPFE driver

General informations

The Linux kernel configuration item CONFIG_BRCMSTB_DPFE has multiple definitions:

Broadcom STB DPFE driver found in drivers/memory/Kconfig

The configuration item CONFIG_BRCMSTB_DPFE:

• prompt: Broadcom STB DPFE driver
• type: tristate
• depends on: CONFIG_ARCH_BRCMSTB || CONFIG_COMPILE_TEST
• defined in drivers/memory/Kconfig
• found in Linux kernels: 5.16–5.19, 6.0–6.12
• modules built: brcmstb_dpfe

Help text

This driver provides access to the DPFE interface of Broadcom STB SoCs. The firmware running on the DCPU inside the DDR PHY can provide current information about the system's RAM, for instance the DRAM refresh rate. This can be used as an indirect indicator for the DRAM's temperature. Slower refresh rate means cooler RAM, higher refresh rate means hotter RAM.
