Documentation

Overview

Package firmware contains remote Tast tests that exercise the firmware.

These tests typically perform operations that are risky or impossible to do in a local test such as suspending or rebooting the DUT.

Functions

func APBmpblk

func APBmpblk(ctx context.Context, s *testing.State)

APBmpblk inspects coreboot contents for indicators of bitmap block configuration. See https://chromium.googlesource.com/chromiumos/platform/bmpblk for more context.

func BIOSCodeAB

func BIOSCodeAB(ctx context.Context, s *testing.State)

BIOSCodeAB reboots the EC, and looks for Port 80 code 0xab. On x86 platforms, depthcharge sends Port 80 code 0xab just before starting the kernel.

func BaseECUpdate

func BaseECUpdate(ctx context.Context, s *testing.State)

func BatteryCharging

func BatteryCharging(ctx context.Context, s *testing.State)

func BlockingSync

func BlockingSync(ctx context.Context, s *testing.State)

func BootBatteryCutoff

func BootBatteryCutoff(ctx context.Context, s *testing.State)

func BootMode

func BootMode(ctx context.Context, s *testing.State)

func BootTime

func BootTime(ctx context.Context, s *testing.State)

BootTime measures the time from EC boot to the first signal that the AP is booting. This test is not a hard rule, what really matters is the platform.BootPerfServerCrosPerf test. See go/chromeos-boottime for a proposal to revisit this. It appears that this test is not measuring the same thing as "Boot-to-Kernel" or "Boot to chromeball", but should catch a regression in that time.

func BootedDeviceReporter

func BootedDeviceReporter(ctx context.Context, s *testing.State)

func CheckKeyboardBacklightFunctionality

func CheckKeyboardBacklightFunctionality(ctx context.Context, s *testing.State)

func Fixture(ctx context.Context, s *testing.State)

func FlagsPreservation

func FlagsPreservation(ctx context.Context, s *testing.State)

func FpAddEntropy

func FpAddEntropy(ctx context.Context, s *testing.State)

func FpBioWash

func FpBioWash(ctx context.Context, s *testing.State)

func FpCheckWriteProtect

func FpCheckWriteProtect(ctx context.Context, s *testing.State)

FpCheckWriteProtect checks if changes in write protect signal are reflected in FPMCU. This is achieved by setting WP to some known state, checking if wpsw_cur value (from crossystem) reports WP state properly and check if WP state reported by FPMCU is also correct.

func FpFlashFpMcuHello

func FpFlashFpMcuHello(ctx context.Context, s *testing.State)

FpFlashFpMcuHello checks if the flash_fp_mcu script can properly communicate with the FPMCU's ROM/vendor bootloader (not EC RO). This is achieved by invoking flash_fp_mcu with the "--hello" option.

This does not have any preconditions, other than being able to disable the hardware write protect. This is because the *communication* with the bootloader should always be possible, regardless of the firmware/software-wp status of the FPMCU. However, flash_fp_mcu can fail if the FPMCU's FW doesn't respond after being returned to the normal operating mode. See https://source.chromium.org/search?q=file:flash_fp_mcu for behavior.

func FpRDP0

func FpRDP0(ctx context.Context, s *testing.State)

func FpRDP1

func FpRDP1(ctx context.Context, s *testing.State)

FpRDP1 test setup enables RDP level 1 by enabling hardware write protect and then enabling software write protect (with reboot of the EC); the test setup then disables hardware write protect, so that we can perform reads and change RDP levels through the bootloader (only accessible when HW write protect is disabled).

When the test script starts, a read through the bootloader is done without disabling flash protection (changing RDP state). We verify that we are unable to read any data.

Next a read through the bootloader is done, while also disabling flash protection (changing to RDP level 0), which triggers a mass erase. We verify that the bytes in the output are all 0xFF and that the firmware is no longer functional.
