Add keyboard backlight timeout as an option #38

Open german-rios-gonzalez opened 4 years ago

german-rios-gonzalez commented 4 years ago

Hi, first of all thank you very much for this project, the effort and the great results, I came here because by default the keyboard backlight timeout it's about 15 seconds on my Matebook D14 2020, and currently I can't find a way to set the backlight always on, I don't have any knowledge about the kernel internals but I guess you can add this option on this project, this would be wonderful for people that work in dark conditions.

nekr0z commented 4 years ago

Do you know for a fact that changing keyboard backlight timeout is at all possible on yout MateBook?

I don’t really know about D14, but at least for the MateBook 13 I own I know no way to tweak that on any operating system. I was actually under impression it wasn’t possible on any MateBooks.

Hi, @nekr0z I have the model NBL-WAQ9R Matebook D14 2020, the software that comes preinstalled with this laptop have the option to never turn off, I wiped out this operative system but this article show what I'm talking about.

Wow! I had no idea! @aymanbagabas, this is definitely worth looking into.

aymanbagabas commented 4 years ago

Interesting! Could you please provide an ACPI dump? https://01.org/linux-acpi/utilities

german-rios-gonzalez commented 4 years ago

Hi, @aymanbagabas thanks for the link, I followed the instructions and I attached the zipped result file. (For the record I use Fedora as operative system) acpidump.zip

This looks promising, these 2 methods 'looks' like the ones to get/set the keyboard backlight (assuming KBBL stands for KeyBoard BackLight). They appear in the HWMI interface in SSDT5 under 0x0602 and 0x0702.

    Method (GLIV, 1, NotSerialized)
    {
        Name (BUFF, Buffer (0x0100){})
        Name (CONT, Zero)
        Local0 = Arg0
        CreateByteField (BUFF, Zero, STAT)
        CreateByteField (BUFF, One, SURV)
        CreateByteField (BUFF, 0x02, KBBL)
        CONT = Zero
        Acquire (\_SB.PCI0.LPC0.EC0.ECMT, 0x03E8)
        \_SB.PCI0.LPC0.EC0.ECM3 (0xC4)
        While (((CONT != 0x0A) && ((\_SB.PCI0.LPC0.EC0.ECXC & One) == Zero)))
        {
            CONT += One
            Sleep (0x32)
        }

        KBBL = \_SB.PCI0.LPC0.EC0.ECXD
        Release (\_SB.PCI0.LPC0.EC0.ECMT)
        STAT = Zero
        Return (BUFF) /* \GLIV.BUFF */
    }

    Method (SLIV, 1, NotSerialized)
    {
        Name (BUFF, Buffer (0x0100){})
        Local0 = Arg0
        CreateByteField (Arg0, 0x02, KBBV)
        CreateByteField (BUFF, Zero, STAT)
        Acquire (\_SB.PCI0.LPC0.EC0.ECMT, 0x03E8)
        If ((((KBBV == 0x04) || (KBBV == 0x08)) || (KBBV == 0x10)))
        {
            \_SB.PCI0.LPC0.EC0.ECM3 (0xC5)
            \_SB.PCI0.LPC0.EC0.ECD3 (KBBV)
            STAT = Zero
        }
        Else
        {
            STAT = One
        }

        Release (\_SB.PCI0.LPC0.EC0.ECMT)
        Return (BUFF) /* \SLIV.BUFF */
    }

Could you try these commands out and report the output

Hi, @aymanbagabas I get these results for the 3 states of the keyboard backlight

Hahaa, bingo! I gotta try this in my machine. You can see the changes here in the first and last cases (the second seems odd). Looking at the methods, the available values are 0x04, 0x08, and 0x10.

Could you try these with each value and observe the changes to the keyboard backlight

Ok, there is a catch, you gotta run each set of commands twice to get a result, otherwise, you'll get 0x01.

german-rios-gonzalez commented 4 years ago

Sorry for the delay, but I think I screwed again, because I can't see any change, for example this is the value that I need to echo 0x0x040702?? or is 0x040702?

Do you prefer that I add the results as an attachment?

Yeah, after the 0x04 the second time it turn off the backlight, the 0x08 the second time turn on the backlight in level 1, and the 0x10 the second time turn on the backlight on the level 2

aymanbagabas commented 4 years ago

@nekr0z can you confirm this is working on your machine?

nekr0z commented 4 years ago

@nekr0z can you confirm this is working on your machine?

Yes and no. 0x04 followed by a call switches backight to full on my machine (no need to do the commands twice either, once is enough), while 0x08 and 0x10 do nothing. And neither of these commands do anything to the duration of the backlight.

aymanbagabas commented 4 years ago

I guess that's still good news! It means we can control the keyboard backlight from the software. I'll look more into the timeout duration.

nekr0z commented 4 years ago

As for the timeout duration, I don't believe this option was available before 2020, so it may be exclusive to the newer models. I definitely remember the corresponding woes on a forum dedicated to WRT-W19.

That being said, it's cool that keyboard backlight can be controlled from software — even on my model (and I guess on MBX as well?); it's even more cool that at least new models allow for backlight duration control; and it's absolutely great that you're on the right track to figuring these things out. ;)

Don't hesitate to ping me if anything needs testing on a WRT-W19.

aymanbagabas commented 3 years ago

@german-rios-gonzalez can you provide a sudo dmidecode for your computer? I need the device's dmi id to match against it in the driver.

german-rios-gonzalez commented 3 years ago

Hi @aymanbagabas off course

dmidecode 3.2

Getting SMBIOS data from sysfs. SMBIOS 3.11.1 present.

SMBIOS implementations newer than version 3.2.0 are not

fully supported by this version of dmidecode.

Please try https://github.com/aymanbagabas/Huawei-WMI/tree/feat/kbdlight and report the behavior. FYI, I haven't tested it on my machine (I don't have it on me at the moment) so you might encounter kernel panics 🤞

@nekr0z I'd love it if you can test this too. You'd need to load the driver with handle_kbdlight=1 or use the sysfs interface because your device handles this somewhere else, assuming the BIOS, the same goes to my device MACH-WX9. The sysfs interface takes 0, 1, or 2 for off, level 1, level 2 respectively.

nekr0z commented 3 years ago

Ooh, interesting, it works! Well, somewhat. ;-)

I installed the patched driver onto my machine and rebooted. Nothing new.

Then, I rmmoded the driver and insmoded it with handle_kbdlight=1. kbdlight interface appeared under /sys/devices/platform/huawei-wmi/. So far so good.

Now, my WRT-W19 has 3 modes of keyboard lighting: "off" (self-explanatory), "half" (low brighness for about 15 seconds, then turning off), and "full" (bright about 15 seconds, then turning off). The modes are controlled by a dedicated key (combined with F3) and switch in cycle, with one caveat: if the keyboard is in "half" or "full" mode and the lighting has timed out, pushing the key doesn't switch to the next mode, it only turns the lighting on.

Well, here are the results of my playing with kbdlight interface:

german-rios-gonzalez commented 3 years ago

Hi @aymanbagabas, I don't know if I do it all ok, but the keyboard can cycle through the 3 levels of backlight, from off, to medium, to maximum, and the timeout it's off 💃, and there isn't kernel panics signals yet, I'm going to work all day and be right back if anything went wrong

aymanbagabas commented 3 years ago

I finally was able to run this on my machine (MACH-WX9) and I see a couple of differences.

    Method (GLIV, 1, NotSerialized)
    {
        Name (BUFF, Buffer (0x0100){})
        Local0 = Arg0
        CreateByteField (BUFF, Zero, STAT)
        CreateByteField (BUFF, One, AMLL)
        CreateByteField (BUFF, 0x02, KBLL)
        AMLL = 0xFF
        KBLL = \_SB.PCI0.LPCB.EC0.RRAM (0x0C4F)
        STAT = Zero
        Return (BUFF) /* \GLIV.BUFF */
    }

    Method (SLIV, 1, NotSerialized)
    {
        Name (BUFF, Buffer (0x0100){})
        Local0 = Arg0
        CreateByteField (Arg0, 0x02, SOCP)
        CreateByteField (BUFF, Zero, STAT)
        \_SB.PCI0.LPCB.EC0.WRAM (0x0C4F, SOCP)
        STAT = Zero
        Return (BUFF) /* \SLIV.BUFF */
    }

The return buf always returns buf[1] = 0xff and buf[2] has one of the following values 0x01 off, 0x02 level 1, and 0x04 level 2 which is different from what you have. It seems like older models have more quirks and edge cases. I will see what I can do.

aymanbagabas commented 3 years ago

@nekr0z could you please provide a dmidecode output? As this project keeps growing, it's becoming hard to keep track of which device is which. So I'm thinking of building a database of Huawei devices information in the wiki section of this repository.

dmidecode is used to identify platform devices in the kernel and the driver uses those to apply quirks to different devices. From what I've noticed, new devices report kbdlight button presses and they're handled through WMI as opposed to old ones which are handled in the firmware.

aymanbagabas commented 3 years ago

@german-rios-gonzalez your device doesn't seem to have \SKBT and \GKBT introduced in https://github.com/aymanbagabas/Huawei-WMI/pull/44

aymanbagabas commented 3 years ago

@nekr0z @german-rios-gonzalez I've updated https://github.com/aymanbagabas/Huawei-WMI/tree/feat/kbdlight to fix some issues.

@nekr0z I've noticed that whenever I change kbdlight on my machine, the change does not take effect immediately like if it was on level 2 and I set it to off, it takes some time for the change to apply. This might be the case for you as well. However, I think this doesn't matter much because our devices already handle kbdlight just fine, though, it would be nice to control this from the software.

german-rios-gonzalez commented 3 years ago

Hi, @aymanbagabas so far it's working without issues, I didn't notice any drawbacks, the time out it's off and the keyboard backlight it's always on

Here are the two functions \SLIV and \GLIV responsible for set/get the keyboard backlight callable at 0x00000702 and 0x00000602.

On Magicbook Pro 2020 \SLIV does not control the backlight

aymanbagabas commented 3 years ago

How do you control the backlight? On the MACH-WX9, the keyboard backlight button works out of the box. However, using these two functions, I am able to get/set the keyboard backlight, though setting it takes some time to apply which is weird.

nekr0z commented 3 years ago

@nekr0z, acpidump, please acpixtract -a acpidump.out

You want me to publish all the 39 resulting .dats?

You can try get timeout:

On WRT-WX9 this always returns a bunch of 0x00s with a single 0x01in the first position of the second array. The set method you've mentioned does nothing.

On HLYL-WXX9 the keyboard backlight button works also. GLIV always returns STAT = 1. SLIV just doesn't work.

@aymanbagabas, I think, on your device you can read/write timeout value in EC memory.

I can read level backlight on my laptop. od -Ax -t x1 /sys/kernel/debug/ec/ec0/io Turn off: 0000f0 fc 07 00 00 00 00 00 00 03 03 00 00 00 00 00 00 Level 1: 0000f0 fc 07 00 00 00 00 00 00 03 03 00 00 40 00 00 00 Level 2: 0000f0 fc 07 00 00 00 00 00 00 03 03 00 00 80 00 00 00 Also FN led: 0000f0 fc 07 00 00 00 00 00 00 03 03 00 00 02 00 00 00

On my laptom I can read from EC: timeout in seconds, FN mode, FN held down, FN led, Micmute led, BIOS version and release date. And write: timeout in seconds, FN mode.

You're getting 0x01 because you have to run each call twice, look at the implementation of your device's wmi method. This behavior is the same on other devices. Notice WMIC in this code.

@aymanbagabas. Also

GVER return BIOS version 1.03

GVER | 0x00000101 GTSI | 0x00000102 GTMP return 0x26 or 0x27

GTMP | 0x00000202 GPSI always return 5. Because PSIT = 0x05

GPSI | 0x00000402

I'm not sure if those are 'usefull' or not. The only thing I can think of is to check available features based on GVER.

@sermart1234 Could you test \SLIV and \GLIV more? It wouldn't make sense for these functions to behave differently on other devices.

oh. I've already tried calling everything twice. Could you give an example of a sequence of commands?
