Subject: Re: Partial success - Fixing resume from s2ram on S6010

Message-ID: <5395FFD4.9010302@math.tu-berlin.de> (raw)
In-Reply-To: <2086_1402313568_53959B5F_2086_895_1_20140609113155.GN27580@intel.com>
Hi Ville, dear Intel experts,
more on the partial resume from suspend for the S6010. It seems that the
culprit is really the lack of a proper
initialization of the DVO. The minimum sequence to restore the display
does not require to modify the 830 registers
directly, but rather needs to setup the DVO.
xrandr --output DVI1 --mode 640x480
# without this, access to the DVO is blocked, thus
# all the following fails. The above initializes the
# PLLs such that the DVO can be accessed.
modprobe i2c-hid
modprobe i2c-algo-bit
modprobe i2c-dev
modprobe i2c-scmi
modprobe i2c-i801
modprobe i2c-ismt
modprobe i2c-gpio
modprobe i2c-piix4
modprobe i2c-isch
modprobe i2c-mux
modprobe i2c-core
#
# Only the following two are required.
i2cset -y 5 0x38 0x34 0x02
i2cset -y 5 0x38 0x35 0x7f
# This restores the old resolution.
xrandr --output DVI1 --mode 1024x768
Thus, it really seems that the culprit is here that the resume operation
does
not provide access to the DVO correctly.
Greetings,
Thomas
