Thanks for responding. I'm very interested in what you post, but
first I must say that it really doesn't relate to what I intended to
say in my message.
My message was warning about a design "feature" of the board that
limits the total number of bus mastering boards in PCI slots 4 and 5
to one. This was not explained at all in my manual, and needs to be
made very clear to all who might try to sonfigure a BP6 system.
I think that your message shows that your IDE code makes the HPT366
perform wonderfully. Even with shared interrupts. Even with 2.2.18
(with your patches, I presume).
It is interesting that hd[abc] are on the HPT366; I thought that these
would normally be on the Intel 440BX chipset's IDE controler. Your
timings don't include anything on the BX's controler, so we don't see
how the HPT366 compares.
Now, I have some questions.
- is there a "blessed" version of your IDE patches for 2.2.18?
(My recollection was that you've handed off maintenance of the 2.2
version of the patch to someone else so that you can focus on 2.4. I
don't know how that is working out.)
- is there any chance that your IDE patches will make it into the
standard 2.2.x kernel?
(My impression was that AC has left the door open to this, but not yet
invited you in :-)
- While studying the mailing list to glean ideas about my problem, I
came across a posting that raised questions in my mind about
interrupt sharing. The message was posted by Eberhard Moenkeberg
<[EMAIL PROTECTED]> on Tue, 8 Feb 2000 09:43:28 +0100 (MET).
He suggested that SA_INTERRUPT|SA_SHIRQ should be replaced by
just SA_SHIRQ in several drivers of 2.2.14:
block/ide-probe.c
char/bttv.c
scsi/ncr53c8xx.c
scsi/sym53c8xx.c
Do you think that this is correct? I noticed that 2.2.16 (what I'm
running in my RHL6.2) has no such change.
- The BP6 manual suggests that the HPT366 was designed for hard disks
and recommends not using it for other ATA/ATAPI devices such as CD
drives. Do you feel that this recommendation applies to LINUX (i.e.
is it a feature of dubious BIOS or MSWindows drivers, or is it a
limitation of the hardware)?
Thanks for all you've done for LINUX IDE!
