Title:
drm/i915: Drop force_probe requirement for ADL-S
Status in HWE Next:
Fix Released
Status in linux-oem-5.13 package in Ubuntu:
Invalid
Status in linux-oem-5.13 source package in Focal:
Fix Released
Bug description:
[SRU Justification]
[Impact]
ADL-S i915 PCI ID has been in v5.13-rc1 in commit 0883d63b19bbd
("drm/i915/adl_s: Add ADL-S platform info and PCI ids"), but it is
marked require_force_probe currently, therefore early phase development
takes an extra i915.force_probe=4680 boot parameter to enable i915.
[Fix]
Intel should remove this flag sometime later when ADL-S drm is stable
enough. But before that, we can simply remove that flag from adl_s_info in
drivers/gpu/drm/i915/i915_pci.c.
[Test Case]
i915 should be loaded automatically with patched kernel, so do:
$ lsmod|grep i915
i915
[Where problems could occur]
While this is still an alpha platform in development in OEM projects,
this should not introduce trouble for others. As for ADL, troubles are
expected and to be resolved.
========== original bug description ==========
ADL i915 PCI IDs have been in v5.13-rc1 in commit 0883d63b19bbd
("drm/i915/adl_s: Add ADL-S platform info and PCI ids"), but it is marked
require_force_probe. We need drop this requirement from this kernel so that
machines being tested don't need to work around it locally.
