 Posted: Wed Jan 25, 2023 1:21 pm Post subject: [SOLVED] Intel ARC (a770) stuck at "Loading Linux" |
 |
|
I've been using Gentoo for a while, and recently I decided on getting an Intel Arc a770 (Limited Edition) to replace my NVIDIA card as I prefer using musl over glibc and nouveau ins't well-supported on my card and with my monitor.
The problem is when I booted my system, sway wouldn't work and after a while I saw on dmesg and on the Arch Wiki that I'd need to enable i915.force_probe=56a0 as the drivers are considered experimental, and as of now they are considered stable on 6.2. The problem is when force_probe is enabled, I get stuck on "Loading Linux 6.1.8" which usually means that Framebuffer support is disabled in the kernel which isn't the case, I've enabled these according to the Gentoo Wiki just to be safe:
VESA VGA graphics support
EFI-based Framebuffer Support
Simple framebuffer support
The only way to actually log in and use my computer at the moment is to use my iGPU which lets me use sway, or to disable i915.force_probe=56a0 which leaves me without a WM/DE. Any help would be appreciated, thanks!

sqrtd,
is this a notebook ? If yes, it would be wise to enable:
# CONFIG_X86_INTEL_LPSS is not set
Now comes a shot in the dark ...  ... what happens if you disable:
CONFIG_FB_SIMPLE=y
and enable both:
CONFIG_SYSFB_SIMPLEFB
CONFIG_DRM_SIMPLEDRM
?
(be aware this could result also in a stuck at "loading Linux ...") |

Thanks, unfortunately it's still stuck on "loading Linux..." |

Sorry I cannot help further ... maybe the only solution is to wait for 6.2 ...  |

| The 6.2 kernels are up to -rc5, as of this writing. You wrote that the drivers are considered stable in 6.2. Have you tried using kernel 6.2-rc5 (or later, if one is available) to see if it works for you? |

Just tried using gentoo-kernel-bin-6.1.8, and it seems to be working with i915.force_probe=56a0. The issue most likely is with my kernel config, but I'll still try using 6.2-rc5 (or later) with it just to be sure and reply later if it works, thanks! |

Was able to get dmesg running when using the dGPU:
dmesg: https://paste.sr.ht/blob/26e6f5081edfb1f5ade960a6e2f2449ffa5c3d09
dmesg | grep i915:

sqrtd,
This page says that | Code: | | lkddb pci 8086 56a0 .... .... 03.... : CONFIG_DRM_I915 : drivers/gpu/drm/i915/i915_pci.c # in 6.0–6.1, 6.2-rc+HEAD |
that your device ID 56a0, was added in the the 6.0 kernel.
If you | Code: | | grep 56a0 drivers/gpu/drm/i915/i915_pci.c |
do you get any hits?
Its not is my 6.1.1, nor in 6.1.7.

grep 56a0 didn't return any results. But DG2 is there:
grep DG2 drivers/gpu/drm/i915/i915_pci.c
| Code: | #define DG2_FEATURES \
PLATFORM(INTEL_DG2), \
DG2_FEATURES,
DG2_FEATURES,
INTEL_DG2_IDS(&dg2_info), |

SOLVED!
After doing some searching I've found that having these enabled seems to have fixed it:
https://gitlab.freedesktop.org/drm/intel/-/issues/7732
| Code: | CONFIG_DRM_I915=y
CONFIG_DRM_I915_FORCE_PROBE="*"
CONFIG_DRM_I915_CAPTURE_ERROR=y
CONFIG_DRM_I915_COMPRESS_ERROR=y
CONFIG_DRM_I915_USERPTR=y
CONFIG_DRM_I915_GVT=y
CONFIG_DRM_I915_GVT_KVMGT=y
CONFIG_DRM_I915_PXP=y
CONFIG_DRM_I915_REQUEST_TIMEOUT=20000
CONFIG_DRM_I915_FENCE_TIMEOUT=10000
CONFIG_DRM_I915_USERFAULT_AUTOSUSPEND=250
CONFIG_DRM_I915_HEARTBEAT_INTERVAL=2500
CONFIG_DRM_I915_PREEMPT_TIMEOUT=640
CONFIG_DRM_I915_MAX_REQUEST_BUSYWAIT=8000
CONFIG_DRM_I915_STOP_TIMEOUT=100
CONFIG_DRM_I915_TIMESLICE_DURATION=1
CONFIG_SND_HDA_I915=y |
| Code: | CONFIG_INTEL_MEI=y
CONFIG_INTEL_MEI_ME=y
CONFIG_INTEL_MEI_TXE=y
CONFIG_INTEL_MEI_GSC=y
CONFIG_INTEL_MEI_HDCP=y
CONFIG_INTEL_MEI_PXP=y
CONFIG_INTEL_MEI_WDT=y |
| Code: | CONFIG_EXTRA_FIRMWARE="i915/dg2_guc_70.bin i915/dg2_huc_gsc.bin i915/dg2_dmc_ver2_07.bin"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware" |
+ Enabling IOMMU (Intel) related options:
| Code: | CONFIG_IRQ_MSI_IOMMU=y
CONFIG_IOMMU_IOVA=y
CONFIG_IOMMU_API=y
CONFIG_IOMMU_SUPPORT=y
CONFIG_IOMMU_DEFAULT_DMA_LAZY=y
CONFIG_IOMMU_DMA=y
CONFIG_INTEL_IOMMU=y
CONFIG_INTEL_IOMMU_DEFAULT_ON=y
CONFIG_INTEL_IOMMU_FLOPPY_WA=y
CONFIG_INTEL_IOMMU_SCALABLE_MODE_DEFAULT_ON=y |
diff (diff between current config and old one, contains a lot of unrelated changes)
Also make sure to enable i915.force_probe: (don't use force_probe when using kernel 6.2 or higher on Intel Arc)
| Code: | /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="init=/sbin/openrc-init i915.force_probe=56a0" |
