Comment 39 for bug 1691991

hi Daniel,

It is very nice for your to provide a patch for it. For other PCI IDs, I
will check with Huawei team and back to you at next week.

By the way, what is status of first bug ( The busid reported by libdrm on
the arm64 system is "0007:a1:00.0"), has it been accept by upstram? Do you
have bug id for it? Actually, I think we can take both those 2 bugs back to
Huawei or Pearl team in case it is bugs from Kernel.

thanks,
Mao
