[Bug 1729674]

2020-08-10 Thread kai.heng.feng
IIRC, I tested this scenario, and I didn't observe the issue on external
r8152 dongle over the ASMedia xHC host.

The v1 patch I sent was using topology to check, but maintainers didn't
like it.

I'll see if I can come up a "better" version of it so maintainers will
accept it.

[Bug 1803179]

2019-10-25 Thread kai.heng.feng
Laptops with Skylake SoC and later shouldn't need bbswitch. PCIe port PM will 
disable the power of the card.
After nvidia.ko gets unloaded, make sure "power/control" is "auto" for its 
video (e.g. 01:00.0) and audio (e.g. 01:00.1) functions and its upstream bridge 
(use lspci -t to check).
 
In addition to that, these two commits are also required for mainline kernel 
users:

Is it possible to use DMI based quirk to override the tables?

vasthusya,

I also see this issue, but this only happens to reboot.

Do you see this on cold boot?
