genode/repos/libports/run/acpi_suspend.run

#
#  Test to trigger periodically ACPI suspend and resume and periodically
#  trying to restart graphic driver, ps/2, ahci and nvme driver.
#
#  Main test hardware so far:
#  - Lenovo X201 - resume of intel/display + AHCI + PS/2 working
#  - Lenovo T490 - resume of intel/display + NVME + PS/2 working + GPU
#  - Qemu - resume happens, vesa_fb_drv fails, ahci fails, nvme fails
#
#  Not working: vesa_fb_drv nor boot_fb_drv after resume
#  Untested: all other drivers, e.g. nic, wifi, sd_card, usb ... all others
#
#  UART via Intel AMT SOL is most the time not working after resume. Using
#  it may hang up the boot for unknown reasons. On X201 it must not be used to
#  get reliable resume results! However using PCMCIA serial card in X201 seems
#  ok.
#
#  Thereby, by default serial output is disabled by this script for non Qemu.
