|
My dmesg says :
| Code: | [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-4.19.37-gentoo root=UUID=bda16273-fc1d-4b10-be26-9e14bde5064b ro quiet acpi_osi=Linux acpi_backlight=vendor pcie_aspm=force i915.i915_enable_rc6=1 i915.lvds_downclock elevator=noop vt.default_utf8=0

[ 1.133682] i915 0000:00:02.0: Failed to load DMC firmware i915/glk_dmc_ver1_04.bin. Disabling runtime power management.
[ 1.133684] i915 0000:00:02.0: DMC firmware homepage: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915

[ 2.381332] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device |
I think this says I can't load the driver :
| Code: | | [ 1.133677] i915 0000:00:02.0: Direct firmware load for i915/glk_dmc_ver1_04.bin failed with error -2 |
But this one contradicts that :
| Code: | | [ 1.159370] [drm] Initialized i915 1.6.0 20180719 for 0000:00:02.0 on minor 0 |
What's actually happening here?
And one more thing. Am I using the right driver? I have Pentium N5000 with UHD 605. It belongs to geminilake so I thought "glk" in | Code: | | i915/glk_dmc_ver1_04.bin |
says "Geminilake". Is that right?
Here's my full dmesg just in case : https://pastebin.com/EZFfSVzC

gaurav712,
You have i915 built into your kernel. It needs i915/glk_dmc_ver1_04.bin available when it starts, so it needs to be in the kernel binary too.
With the firmware missing, you have missing functionality. | Code: | | Disabling runtime power management. |
at least.
Only part of the driver loaded. Its enough to get an image on the screen.
| Code: | | [ 4.202874] EXT4-fs (sda4): mounted filesystem with ordered data mode. Opts: (null) |
That is root being mounted read only. At that time, /lib/firmware can be read but its too late, i915 has already initialised.
