Is it legal to obtain/share/use reverse engineered by C# dotnet binary decompilation? Or at least "Trust me bro" representation without direct sharing result of decompilation |

No, I have a 10 gen Intel i7-10710U |

Check this #98 (reply in thread) if GUIDs are same it is "WMI1" |

Yep, they are the same |

Actually some EC addresses could be decoded from DSDT, because EC map defined at least twice: named and in address form, we can guess what was encoded in 4 byte ACPI name for first and check addresses in form ??xx or ?xxy, where xx is byte, y - bit If you want to read some ACPI tables (like DSDT) content try this editor MSI forum contain section with mod-BIOSes and mod-ECs Thread about (no) Linux support; Another; Yet another; And another; The last one Admins of the forum say that Linux is not main target which is understandable. Look like no one reported their ticket to support or don't got and shared positive response |

Please suggest list of apps for MSI laptops and it compatibility:
I'm interested in older ones an it cross compatibility. Each device is supported only by one App, unless the opposite is stated on the support page. Some model supports two Apps, but with different BIOS version. Interesting facts - there are at least 2 or 3 method of accessing EC:
About similar case with WinIO on MSI hardware on Reddit WinIO returns 4 byte for each requested address, 1 current and 3 next. On write WinIO require all 4 bytes as uint32, so usage is quite dangerous if we mess with some important realtime value after it had been changed by hardware. All Apps contain some WMI code called WMI1:
WMI2: (Also shares same BMOF code inside)
MOF code from older Apps is extended in newer with WMI2 section Some EFI vars store info and preferences for model, like Win-FN swap direction. But possibly it's just temp storage. [TODO] |

Info from DSDT table by https://github.com/aymanbagabas/bmf2mof.wasm Technically speaking, I think that MSI app interact with some BIOS backend via WMI, not EC RAM directly, but also part of this code stored inside the driver. MTDE _WDG B2526ED4-CB45-49FA-9230-8D2FE8AFB8EC

@teackot Here is pattern of used addresses from DSDT. Can you share your model name and DSDT dump saved in txt (because Github restricts uploading binary files in issues, or try pastebin) sudo cat /sys/firmware/acpi/tables/DSDT > dsdt.txt
In my case there were two EC sequences. ImHex [Remove .txt at the end of filename] five.hexpat.txt Some values are named but unused inside DSDT code, some intersects inside both tables
But anyway many addresses is not highlighted |

Memory "fields" addressing in ACPI, as it turned out, is not linear as you can assume after looking at mapped address space, which look like this: Field (EC, ByteAcc, NoLock, Preserve){
...
a, 8,
b, 1,
c, 3,
, 4,
d, 16,
...
}I've assumed that they are mapped linearly. Possibly, this mode is present, when b = EC[n] & 1;
c = (EC[n] & 0b00001110) >> 1;Correct me if I'm wrong, please. |

Are you still collecting USB PCAP dumps for new hardware? If so, where do we submit them? I have a GE76 which I'm trying to get the keyboard perkey RGB to turn on -- just turning on would be nice, changing colors isn't necessary. |

Hi, we're doing only EC related stuff. So you probably need to ask the OpenRGB community. Some laptops may have keyboard backlight control from the EC and USB, but they are rare. Please follow their guide https://gitlab.com/OpenRGBDevelopers/OpenRGB-Wiki/-/blob/stable/OpenRGB-doesn't-have-my-device.md If you want to check, is it possible to control keyboard BL brightness from the EC, please follow firmware request template. Please make few dumps with different brightness and share them. I hope that your laptop have some keyboard BL brightness buttons |

I checked DSDT from my ASUS (TUF x505) laptop, and it's way more complicated. It annotates 2 WMI devices WMI0 and ATKD, 1 WMI0 event with 32 bit variable, which notified in 1 method. And 1 ATKD event, which is not included in MOF file. Should I check what event returns on ASUS, or it is useless? Spoiler: DSDT codeWMI0Method (_WED, 1, NotSerialized) // _Wxx: Wake Event, xx=0x00-0xFF
{
Return (Arg0)
}And only 1 place where it notified in DSDT Method (NTFY, 1, Serialized)
{
XVCD = Arg0
Notify (WMI0, 0x80) // Status Change
}ATKD Method (_WED, 1, NotSerialized) // _Wxx: Wake Event, xx=0x00-0xFF
{
If ((Arg0 == 0xFF))
{
Return (GANQ ())
}
Return (One)
}
///

{

If (AQNO)
{

Local0 = DerefOf (ATKQ [AQHI])

AQHI &= 0x0F
Return (Local0)
}
Return (One)

Tje ASUS event should have nothing to do with the MSI WMI interface, do they share GUIDs? |

no, only thing they share is event format, which is (u/s)int32, but i don't know how it packed plus, ASUS have awesome community which support the majority of modern laptops |

@Wer-Wolf Hello again. Today I've discovered 2 extra devices with misconfigured ECDT in addition to mine In mine case all "variables" were mapped to Other two devices are mapping EC as One user of affected device reported slow EC access through Different user reported that mute leds control worked roughly 1/3 times, which might be result of mutex lock in Additionally, on same device people reported that led issue was fixed, when I assume that in this mode EC sends more events from FN keys and other sources, which forces update of memory.

Cool, i will try to upstream this fix into the mainline linux kernel. Do you have an email address i can use for the Trested-by tag of this patch? |

@Wer-Wolf Yes, you can use glpnk <at> proton.me |

It's weird why that Lenovo ThinkBook have failed to init EC, when it had identical settings in DSDT, and ECDT usage was blocked. I'm still waiting for 6.16 to be released on Arch, so I've not tested yet. |

ACPI EC inits correctly on 6.16 |

Preamble
Thanks all who shared EC dumps.
For better readability screenshots made with this HexPat
Model naming
Model name regularly contain display size and CPU generation. For newer devices is easy to spot as part of model name something like 10-11-12-13... for Intel 10+gen based and 3-4-5-7... for AMD Ryzen based CPU/SoC. Older Intel i3/i5/i7 based devices follows same rule but it submission to this repo is rare. Some models submitted without EC dump or full name.
EC firmware naming
Most fresh models named like
abcdEMS1.ver, whereabfrequently but not always equals to screen diagonal,bcis some model code,EMS1is something,veris version number.Some models have
xxxxEMS2or different code but it structure seems near the sameSeems that
xxxxpart in EC name is mainboard or model codename.Look at the value
Motherboard -> Modeland compare it toBIOS Version.Source #66 @benitozh
Intel VS AMD
Intel 10+gen have shift, backlight, fan settings on
0xD_addresses.AMD Ryzen models - on
0xF_addresses.Older Intel requires more data and research.
[For now] Unusual models
16K2ED61.101not likexxxxEMS1#8817G1EMS2.106withEMS2#82Older models
Very unusual model+release datetime from #35
168AEMS1 Ver4.04, 05/31/2010but followsxxxxEMS1patternExperiments [DO NOT RETRY it can destroy your hardware]
If I understood correctly in #64 @vt92i tried to fix broken keyboard backlight. For this he wrote
0xFFto all EC registers and this somehow impacted some default values, some of them seemedreadonlybut some wasread/wright.Highlighted values with binary pattern
?4. Some other values are changed too, like datetime in EC name/Deltas
Very similar AMD based devices.
Some values could be ignored, but range
0x30-4flooks interesting.AMD based device with EC name
IMS1look similar to Intel based device withEMS1(which is more submitted)In many cases
EMS1AMD and Intel devices is less compatibleIf you have model with different from usual
xxxxEMS1.verEC firmware name please send it dumpBeta Was this translation helpful? Give feedback.
