Hi Thomas,

Here is my list (MACH_LOONGSON64):

Loongson 3A3000 CPU + AMD RS780E bridge chip
works well with the mainline kernel linux-5.6-rc3.

Loongson 3A3000 CPU + Loongson 7A1000 bridge chip
only works well with the Loongnix kernel [1]
which is an internal version of Loongson company.

Loongson 3A4000 CPU + Loongson 7A1000 bridge chip
only works well with the Loongnix kernel [1]
which is an internal version of Loongson company.

In order to support Loongson 7A1000 bridge chip,
the Loongson kernel team is working hard to refactor
the code to submit patches to the mainline kernel.

Thanks,

Tiezhu Yang
