Hi, This is because of a newly merged patch from Armin Wolf: https://lore.kernel.org/platform-driver-x86/20240226193557.2888-2-W_Armin@xxxxxx/ You can comment that line or apply that patch to your tree to make it compile. Also, you'll probablyneed to change the call to wmidev_block_set in casper_query function with wmi_set_block (which is now deprecated). > I would *love* to see this driver actually hit mainline repos, and > eventually the upcoming kernel releases, given how much I need to use > this laptop of mine as a computer engineering student. > > Asking just for the case I manage to get this driver up and going on > my end somehow: Is there a tool made for controlling the LED colors yet? > I can still use CLI tools much like on ASUS ROG series laptops, but it > would be much easier and more appreciated to have a GUI provided > Excalibur series laptops' LED lights can virtually take any color in > the RGB space - At least that's how I interpreted with the > configurations I used to do on mine using Excalibur Control Center > on Windows 10/11. No, there isn't a tool yet but controlling leds via sysfs ispretty easy. For example, if you wanted to change the left led zone's color to red: ``` # echo 0xff0000 > /sys/class/leds/casper\:\:kbd_zoned_backlight-left/multi_intensity ``` And don't forget that all leds' initial brightnesses are 0. Also, I'm planning to add support for this API in OpenRGB. > And as for the profiles, let me make sure we're talking about the same > thing in this term: You're talking about the "Office", "Gaming" and > "High Performance" modes as seen in Excalibur Control Center, right? For laptops with 11th gen processors or newer: yes. For laptops with 10th gen processors or older: no, there are 4 power profiles for these laptops (High Performance, Gaming, Text Mode andPower save). > If so, can this be somehow integrated into `power-profiles-daemon` > SystemD service for easier controlling with GNOME and other DEs that > use it?

Yes, power-profiles-daemon is already integrated with platform_profile. > Please do CC me and the people I've added to the CC list with this email > of mine on the upcoming revisions, if any.
