Hello

Thank you for your interest and patience!

Sorry for the delay in providing more information. The only method I had to
transfer test kernels onto the Q40 was painfully slow and involved swapping
ISA cards which is itself problematic as the pins in one of the ISA slots are
breaking.

In the end I decided my best option was to dispose of the standard operating
system (SMSQ/E) and write a new boot ROM for the machine with support for
FAT32 filesystems on an IDE disk and TFTP transfers using an NE2000 card.
It's still in development but is now working well enough to use. The source
code is at https://github.com/willsowerbutts/q40boot

During the process I learned a bit more about the Q40 hardware, and
transferring a kernel now takes 7 seconds instead of over 20 minutes.

I've run the various tests as requested;

* 5.13.19 -- IDE works (but the data on disk is byte-swapped, see below)

* 5.13.19+44b1fbc0f5f30e66a56d29575349f0b1ebe2b0ee -- IDE fails (crash)

* 5.14.21 -- IDE fails (crash)

* 6.4.10 + Michael's RFC patch -- IDE fails (no crash, but "Bad IO access")

* 6.4.10 + my patch -- IDE works, data on disk is NOT byte-swapped

Copies of the boot output for each kernel are attached to this email.

I've also attached the patch I am currently using on my Q40 kernel. It's
based in part on Michael's patch. It bodges up "ioport_map" to apply the
offset required to convert raw ISA address into "cookies" and thus allow the
IDE to work without "Bad IO" complaints. To be crystal clear I am NOT
proposing this as a solution, it's obviously a hack job, but I wanted to
illustrate at least one way that *does* work on the Q40.

I think one proper solution might involve enabling CONFIG_HAS_IOPORT_MAP but
I've not yet looked properly into the implications of doing so. I'm very open
to alternative solutions too.

As a side note, the NE2000 driver, which is also using 8- and 16-bit ISA I/O,
works correctly with both 5.13 and 6.4. If one allows it to auto-probe the
card's interrupt it locks up the machine due to limitations of the interrupt
controller, but I understand this was always the case; I've made a tiny patch
to ne.c to prevent it trying this.

The W83757 on my ISA IO card, and the W83787IF on the ISA IO card that
shipped with the machine, are configurable only using jumpers. They can only
use the two standard base addresses (0x1F0 or 0x170).

I wonder if this is a misunderstanding about Q40 IDE.

The Q40 does not have an on-board IDE controller. IDE is accessed via a
common ISA PC Super-IO card. When you do a 16-bit transfer from the ISA I/O
address the data comes out backwards and the CPU needs to byteswap it.

I found it interesting and quite unexpected that 5.13 read data from the IDE
drive byte-swapped. I had prepared a drive for the machine with an MBR
partition table and an ext4 filesystem but the kernel did not recognise
either. After a while I realised I had to byte swap the entire drive with
'dd conv=swab', and then it worked.

For my 6.4 patch I enabled byte swapping in the pata_falcon_data_xfer()
function -- this allows me to use an IDE drive with everything in the
normal/compatible byte ordering, which makes life much easier. I assume this
is the intended behaviour.

I wonder if any existing Q40 users are actually storing all the data on their
drives byte-swapped just to avoid the overhead of byte-swapping on every
read/write. I suppose this would work just fine until you need to connect
that drive to another machine.

For my Q40boot ROM I wrote an IDE driver. It just treats the IDE interface as
a regular legacy PC style IDE interface (which is exactly what it is!) plus
byte swapping of 16-bit transfers. See the functions q40_ide_read_sector_data
and q40_ide_write_sector_data in the IDE driver (q40ide.c, q40isa.h in the
q40boot github repository linked above).

I am going to look at the pata_legacy driver and see if it might be usable on
the Q40 instead of pata_falcon.

As a long term fix I think I need to read up on CONFIG_HAS_IOPORT_MAP to try
and understand how I might enable this. I expect enabling it will have
implications for all M68K machines, so maybe someone with more experience
should be making that decision.

I would be very happy to run further tests or to rewrite my hacky patch in
response to pointers on how to improve it.

Thanks

Will
