Re: Bug#970395: firmware-nonfree: Please add AMD-SEV firmware files (amd-folder) to close CVE-2019-9836 on specific EPYC-CPUs



Dear Henrique,

It be great to get your input, hence repinging (;

Especially as linux-firmware is the common upstream source, it be ideal to ship
the amd64 mircrocode out of our firmware packages.

Thanks for letting us know.

kind regards,
maximilian
