Subject: [PATCH v4 0/1] x86/PCI: Ignore E820 reservations for bridge windows on newer systems
Date: Thu, 14 Oct 2021 17:39:07 +0200 [thread overview]
Message-ID: <20211014153908.4812-1-hdegoede@redhat.com> (raw)
Hi All,
Here is v4 of my patch to address the E820 reservations vs PCI host bridge
ranges issue which are causing touchpad and/or thunderbolt issues on many
different laptop models.
I believe that this is ready for merging now.
Bjorn, can you review/ack this please ?
x86/tip folks it would be ideal if you can pick this up and send it out
as a fix to Linus for 5.15. This fixes a bug which has been plaguing a
lot of users (see all the bug links in the commit msg).
Regards,
Hans
