Subject: [Qemu-devel] [PATCH 2/3] fdc: Fix false FD_SR0_SEEK
Date: Tue, 4 Sep 2012 11:46:55 +0200 [thread overview]
Message-ID: <1346752016-3569-3-git-send-email-kwolf@redhat.com> (raw)
In-Reply-To: <1346752016-3569-1-git-send-email-kwolf@redhat.com>
fdctrl_start/stop_transfer() used to set FD_SR0_SEEK no matter if
there actually was a seek or not. This is obviously wrong.
fdctrl_start_transfer() has this information because it performs the
seek itself. fdctrl_stop_transfer() gets status0 passed and callers
already take care of setting FD_SR0_SEEK where appropriate.
