The hardware mailboxes are used by the driver to submit requests to firmware and receive the completion notices from hardware. Initially, a management mailbox channel is up and running. The driver may request firmware to create/destroy more channels dynamically through management channel. Add driver internal mailbox interfaces. - create/destroy a mailbox channel instance - send a message to the firmware through a specific channel - wait for a notification from the specific channel Co-developed-by: George Yang <George.Yang@amd.com> Signed-off-by: George Yang <George.Yang@amd.com> Co-developed-by: Min Ma <min.ma@amd.com> Signed-off-by: Min Ma <min.ma@amd.com> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Lizhi Hou <lizhi.hou@amd.com> Signed-off-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241118172942.2014541-4-lizhi.hou@amd.com
