+ * NOTES about DMA transfers:
+ *
+ * controller 1: channels 0-3, byte operations, ports 00-1F
+ * controller 2: channels 4-7, word operations, ports C0-DF
+ *
+ * - ALL registers are 8 bits only, regardless of transfer size
+ * - channel 4 is not used - cascades 1 into 2.
+ * - channels 0-3 are byte - addresses/counts are for physical bytes
+ * - channels 5-7 are word - addresses/counts are for physical words
+ * - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
+ * - transfer count loaded to registers is 1 less than actual count
+ * - controller 2 offsets are all even (2x offsets for controller 1)
+ * - page registers for 5-7 don't use data bit 0, represent 128K pages
+ * - page registers for 0-3 use bit 0, represent 64K pages
+ *
+ * DMA transfers are limited to the lower 16MB of _physical_ memory.
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ * Address mapping for channels 0-3:
+ *
+ * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
+ * | ... | | ... | | ... |
+ * | ... | | ... | | ... |
+ * | ... | | ... | | ... |
+ * P7 ... P0 A7 ... A0 A7 ... A0
+ * | Page | Addr MSB | Addr LSB | (DMA registers)
+ *
+ * Address mapping for channels 5-7:
+ *
+ * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
+ * | ... | \ \ ... \ \ \ ... \ \
+ * | ... | \ \ ... \ \ \ ... \ (not used)
+ * | ... | \ \ ... \ \ \ ... \
+ * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
+ * | Page | Addr MSB | Addr LSB | (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
+ * and up to 128K bytes may be transferred on channels 5-7 in one operation.

This is additional patch to support NEC PC-9800 subarchitecture
against 2.5.62-ac1. (17/21)
Serial port support for PC98.
- Patch for onboard modem.
- New driver for 1st COM port.
PC98 has 2 COM ports. 1st port uses 8251 upper compatible chip
and 2nd port uses 16550A compatible chip.
Regards,
Osamu Tomita

#ifdef __KERNEL__
This is additional patch to support NEC PC-9800 subarchitecture
against 2.5.62-ac1. (16/21)
SCSI host adapter support.
- BIOS parameter change for PC98.
- Add pc980155 driver for old PC98.
- wd33c93.c compile fix.
Regards,
Osamu Tomita

This is additional patch to support NEC PC-9800 subarchitecture
against 2.5.62-ac1. (12/21)
Small changes for PCI support.
Fix for difference of IRQ numbers and IO addresses.

I think this should be made unconditionally. There's no reason why

This is horribly ugly. Just do an inkernel ioctl instead. Something
like the following (untested!):
struct hd_geometry geo;
int err;
err = ioctl_by_bdev(bdev, HDIO_GETGEO, &geo);
if (err)
return err;
g_head = geo.heads;
g_sect = geo.sectors;

this is still not good - you shouldn't expose struct scsi_disk outside
sd.c. Please change the pc98_bios_param() prototype to that of the
bios_param entry point (direct passing of capacity).
Can you explain what this first_real_host() stuff is for - we need some
way to handle this better.

no need to initialize to zero - it's in .bss and thus cleared implicitly.

Move that all into the actual c source file. In addition all those

the way this is done is ugly. I'm still not sure how this is done
best. When do you need the pc98 geometry exactly? i.e. can it happen
with one of the existing linux scsi drivers?

The wd33c93 changes are ugly as hell, but that's not your fault. I'll
try to rework it to abstract out the different implementations better.
Could you perform some testing for me if I send you updated versions?

How does the pc98 store filenames containing kana and kanji? Maybe
this is a complete non-issue, but it occurred to me, so I thought I'd
mention it.

Thank very much. I didn't know inkernel ioctl. I'll try it.

This is solved by using ioctl_by_bdev() in your suggestion. Thanks.

PC98 BIOS create geometry table on boottime orderd by SCSI ID.
We read that to get geometry. If ide-scsi exist we mis-read table.
.
.
(Snipped, but I'll fix them. Thanks.)

We need BIOS geometry exactly to create a partion on linux (by fdisk or
GNU/parted). BIOS uses C/H/S access on boottime according to partition
table. If BIOS geometry is not exact, fail to boot from the partition.
I recived the report about this problem from people using advansys driver
without PC98 patch.

Yes, of course.

This is additional patch to support NEC PC-9800 subarchitecture
against 2.5.62-ac1. (16/21) re-send
I re-write this patch. Comment please.
SCSI host adapter support.
- BIOS parameter change for PC98.
- Add pc980155 driver for old PC98.
- wd33c93.c compile fix.

This is additional patch to support NEC PC-9800 subarchitecture
against 2.5.62-ac1. (6/21) re-send
Thanks. I re-wrote patch and tested on my Box.
FAT fs and partition table support for PC98.
FAT fs created by PC9800 MS-DOS has curious media descripter. (BUG?)

Maybe add a small comment here describing it's needed for PC98 dos?
BTW: Linux codingstyle sais it should be written as
if (FAT_FIRST_ENT(sb, media) != first &&
(media != 0xf8 || FAT_FIRST_ENT(sb, 0xfe) != first)) {
Also please split this patch up into one to the fat file system
and one to the partition code.
Otherwise this patch looks nice to me.

By any chance, you don't have fixes for the wd33c93 abort and reset handling
(.eh_{abort,bus_reset}_handler)?

I'm testing PC98 patch for 2.5.64(-ac3).
I try to implement error handler in pc980155 driver that uses wd33c93.c.
I'll post them soon.
Thanks,
