DRM KMOD version drm-61-kmod 6.1.92

To Reproduce Install an Intel A380 card. The one used here is an ASRock Intel Arc A380 Low Profile.

Then do either:

sudo kldload i915kms

or start Xorg with the "intel" driver.

Screenshots intel_debug

Additional context

lin72h commented 1 month ago

I think you need newly merged 6.6-drm-kmod for intel discrete GPU

oyvinht commented 1 month ago

Oh, right, thanks. That requires 15-CURRENT to compile, I guess.

oyvinht commented 4 weeks ago

For what it's worth, I complied drm-kmod on 14-stable, and did some rudimentary debugging.

For now, I discovered that I could at least replace the normal UEFI framebuffer and switch the console to 3840 x 2160 by commenting out from drivers/gpu/drm/i915/i915_gem.c:

@@ -1192,12 +1192,12 @@ int i915_gem_init(struct drm_i915_private *dev_priv)
         * FIXME: break up the workarounds and apply them at the right time!
         */
        intel_clock_gating_init(dev_priv);
-
+        /*
        for_each_gt(gt, dev_priv, i) {
                ret = intel_gt_init(gt);
                if (ret)
                        goto err_unlock;
-       }
+       }*/

and add a return before setting ppgtt->vm.insert_page = gen8_ppgtt_insert_entry; in drivers/gpu/drm/i915/gt/gen8_ppgtt.c.

I'll see if I can find the time to debug a little deeper.

It crashed on starting X with modesetting, though (I have no debugger screenshot).
