This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Fix] Coalesce host bridge contiguous apertures so the resources requested by child devices can be met. [Test] Boot affected systems. No picture from the iGPU. With the patch applied, iGPU can work normally. [Where problems could occur] Assume there are device A and device B and they request overlapped resource region, the original logic may not be able to allocate enough resource for A so device B claimed the resource in the end. Once the fix is applied, the region may be big enough for device A, hence device B won't be able to get the resource it needs. Hopefully we don't have such broken systems.
