could you please provide us your DSDT and the exact model string of your TT?
I looked a bit through the patch and I see that it is restricted
to MM and (forgotten the model number).
MM? What does it stand for?
I have a VGN-Z11 which has
also a turn on/off optical drive, a shock sensor etc.
This last one is interesting because, from the other DSTDs I have seen,
I suspect your notebook to have handle 0x0113, an handle that allows to
enable/disable an unknown feature, is it the HDD protection?
(btw, I also take care for the sony-laptop-zseries variant of the
kernel module where you can turn off and on the nvidia card,
and also the led of the speed-stamina switch is controlled.
This is interesting too. Ok, let's not speak about the multiplexer
methods, let us speak about handle 0x0128, related to the Hybrid GFX
feature. I have never done a deep analysis, maybe you can help here.
First of all, newer VPCZ1 models come with a few more methods, dealing
with the screen brightness level, HSC5, HSC6, HSC7. Then:
- HSC0 returns the event reason (1 switch position change? what about
2,3,4?)
- HSC1 returns some state bits (what about their meaning?)
- HSC2, HSC3, HSC4?
Moreover:
Field (ECF2, ByteAcc, Lock, Preserve)
{
Offset (0xF1),
HPWR, 1, <-- ?
HLMX, 1, <-- ?
HCMM, 1, <-- ?
DLED, 1, <-- discrete GFX led
ILED, 1, <-- integr. GFX led
ALED, 1, <-- auto GFX led
Offset (0xF2),
SWPS, 1, <-- ?
HPOK, 1, <-- ?
HHPD, 1, <-- HDMI related
DHPD, 1, <-- DVI related
ATSW, 1 <-- auto switching related
}
What does handle 0x0128 aim to provide?
