2 bool "Google Firmware Drivers"
5 These firmware drivers are used by Google's servers. They are
6 only useful if you are working directly on one of their
7 proprietary servers. If in doubt, say "N".
12 tristate "SMI interface for Google platforms"
13 depends on X86 && ACPI && DMI
15 Say Y here if you want to enable SMI callbacks for Google
16 platforms. This provides an interface for writing to and
17 clearing the event log. If EFI_VARS is also enabled this
18 driver provides an interface for reading and writing NVRAM
21 config GOOGLE_COREBOOT_TABLE
22 tristate "Coreboot Table Access"
25 This option enables the coreboot_table module, which provides other
26 firmware modules access to the coreboot table. The coreboot table
27 pointer is accessed through the ACPI "GOOGCB00" object or the
28 device tree node /firmware/coreboot.
31 config GOOGLE_COREBOOT_TABLE_ACPI
33 select GOOGLE_COREBOOT_TABLE

43 config GOOGLE_MEMCONSOLE_X86_LEGACY
44 tristate "Firmware Memory Console - X86 Legacy support"
45 depends on X86 && ACPI && DMI
46 select GOOGLE_MEMCONSOLE
48 This option enables the kernel to search for a firmware log in
49 the EBDA on Google servers. If found, this log is exported to
50 userland in the file /sys/firmware/log.
52 config GOOGLE_FRAMEBUFFER_COREBOOT
53 tristate "Coreboot Framebuffer"
55 depends on GOOGLE_COREBOOT_TABLE
57 This option enables the kernel to search for a framebuffer in
58 the coreboot table. If found, it is registered with simplefb.
60 config GOOGLE_MEMCONSOLE_COREBOOT
61 tristate "Firmware Memory Console"
62 depends on GOOGLE_COREBOOT_TABLE
63 select GOOGLE_MEMCONSOLE
65 This option enables the kernel to search for a firmware log in
66 the coreboot table. If found, this log is exported to userland
67 in the file /sys/firmware/log.
70 tristate "Vital Product Data"
71 depends on GOOGLE_COREBOOT_TABLE
73 This option enables the kernel to expose the content of Google VPD
74 under /sys/firmware/vpd.
