Hi Robert,
Thank you for your reply, and patch, but it seems the patch will not
apply cleanly.
[root@laptop /usr/src/sys/dev/drm]# patch -p0 < i855-no-attach-sec.patch
Hmm... Looks like a unified diff to me...
The text leading up to this was:
--------------------------
|Index: i915_drv.c
|===================================================================
|--- i915_drv.c (revision 183406)
|+++ i915_drv.c (working copy)
--------------------------
Patching file i915_drv.c using Plan A...
Hunk #1 failed at 85.
1 out of 1 hunks failed--saving rejects to i915_drv.c.rej

[root@laptop /usr/src/sys/dev/drm]# cat i915_drv.c.rej

*** 85,90 ****
{
drm_device_t *dev = device_get_softc(nbdev);
bzero(dev, sizeof(drm_device_t));
i915_configure(dev);
return drm_attach(nbdev, i915_pciidlist);
--- 85,93 ----
{
drm_device_t *dev = device_get_softc(nbdev);
+ if (device_get_unit(nbdev))
+ return 0;
+
bzero(dev, sizeof(drm_device_t));
i915_configure(dev);
return drm_attach(nbdev, i915_pciidlist);
I added the 2 lines manually. So the function looks like this:
static int
i915_attach(device_t nbdev)
{
drm_device_t *dev = device_get_softc(nbdev);
if (device_get_unit(nbdev))
return 0;
bzero(dev, sizeof(drm_device_t));
i915_configure(dev);
return drm_attach(nbdev, i915_pciidlist);
}
Will rebuild and test..
Thanks!
