Bug description:
[Impact]
E820 reserved retire memory window, and make other hot-added devices unable
to get the required memory window.
[Fix]
It only can be fixed by a list of quirk to mark those machines out, and
requires below commits from v5.19-rc1 and v5.19-rc3
a2b36ffbf5b6 x86/PCI: Revert "x86/PCI: Clip only host bridge windows for E820
regions"
d341838d776a x86/PCI: Disable E820 reserved region clipping via quirks
fa6dae5d8208 x86/PCI: Add kernel cmdline options to use/ignore E820 reserved
regions
4c5e242d3e93 x86/PCI: Clip only host bridge windows for E820 regions
31bf0f433325 x86: Log resource clipping for E820 regions
93d256cd3c1e x86/PCI: Eliminate remove_e820_regions() common subexpressions
[Test]
Verified by the bug reporter.
[Where problems could occur]
The 6 commits are all clean cherry-picked, and the sixth commit reverts the
third commit which are the 2 commits that do real functional changes.
a2b36ffbf5b6 ("x86/PCI: Revert \"x86/PCI: Clip only host bridge windows for
E820 regions\"")
4c5e242d3e93 ("x86/PCI: Clip only host bridge windows for E820 regions")
The fourth and and fifth commits introduce a new quirk to ignore E820
reserved regions and the quirk only affects the listed machines.
Drivers that operates E820 table may fail if we ignore the E820 regions, but
it should have no impact on the listed consumer PCs.
===============================================
Touchpad is not working at all on ACER Spin 5 SP513-54N.
According to
https://wiki.ubuntu.com/DebuggingTouchpadDetection#In_case_your_Touchpad_doesn.27t_work_at_all_.28No_response_from_the_Touchpad.29
I am creating this kernel bug issue.
There are more issues, too, like touchscreen not working and Ubuntu
not installable - see here if interrested
https://askubuntu.com/questions/1251719/
I would like to run Ubuntu on this machine and I am willing to help
with any debug or kernel tweaking... Please let me know.
