This is called "busy polling" and there must be a better way to do it.
Has this code been profiled to examine typical actual delay lengths ?

There are codes like;
int tout = sc->sc_wc;
;
while (slp->sl_scp.scp_datalen > 0 && tout -- > 0)
{
;
}
To calculate the tout we use;
sc->sc_wc = delaycount * 2000; /* 2 sec */
And we initialize the delaycount in clock.c.

[CFR] ncv, nsp, stg SCSI drivers
Call for review, ncv, nsp, and stg SCSI drivers which are ported from NetBSD/pc98. I would like to merge to current and do MFC. ncv: NCR 53C500 based SCSI PC-CARDs nsp: Ninja SCSI-3 based SCSI PC-CARDs stg: TMC 18C30 based SCSI PC-Cards and ISA cards. They are tested and working on PAO3 and there are entries (totally 19) in /etc/pccard.conf, though commented out. I would like to have review especially on the changes in i386/isa/clock.c for counting delay loop numbers, and converts of SCSI layer from NetBSD one to CAM in cam/scsi/scsi_low.[ch] . They can be obtained from http://home.jp.freebsd.org/~non/scsi_low-2926.tar.gz (added files) http://home.jp.freebsd.org/~non/scsi_low-2926.diff.gz (diff to current) http://home.jp.freebsd.org/~non/scsi_low4-2926.diff.gz (diff to stable) You will need the tar.gz file and one of diff.gz file. // Noriaki Mitsunaga To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
