Subject: [Qemu-devel] AHCI / Sata port initial error status
Date: Mon, 30 Jun 2014 15:14:31 -0400 [thread overview]
Message-ID: <53B1B717.6070205@redhat.com> (raw)
I am in the process of writing a series of AHCI tests (for q35) that
compare the written specifications against what the current device
emulation actually does, and I was curious about this bit instead of
ahci.c, in ahci_reset_port:
ide_state->error = 1;
What does this error signify, exactly, and why is it set by default on
ports with a device attached? It trickles up inside of the PxTFD.ERR
byte in the HBA as well as showing up in the initial Register D2H FIS
after the PxCMD.FRE bit is set.
Thank you,
--John.
