This is the patch to support NEC PC-9800 subarchitecture
against 2.5.64-ac4. (1/11)
PC98 Standard console support (without japanese kanji character).
Text mode video card on PC98 is useing 2bytes of VRAM by 1 character to
support japanese kanji character. VRAM for attributes is mapped another
address (+0x2000).
Character codes 0x80-0xff are diffrent with standerd PC.

+ * 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

This is the patch to support NEC PC-9800 subarchitecture
against 2.5.64-ac4. (4/11)
PC98 standard IDE I/F support.
- Change default IO port address and IRQ.
- Add chipset "ide_pc9800".
- Add IDE0/1 select function becase PC98 uses common IO port to access them.
- Request region exactly for other optional cards.
- Get BIOS C/H/S parameter for PC98.

This is the patch to support NEC PC-9800 subarchitecture
against 2.5.64-ac4. (2/11)
Small patches for PC98 core support.
io.h: Using ioport 0x5f to wait is recomended by vendor.
irq.h: Cascade IRQ is 7 for PC98 not 2.
pc98*.h: Add macros to access BIOS parameters.
kernel.h: define "pc98" for other files.
I think these are small and clean.

MicroChannel Architecture is found in some IBM PS/2 machines and
laptops. It is a bus system similar to PCI or ISA. See
This is the patch to support NEC PC-9800 subarchitecture
against 2.5.64-ac4. (7/11)
C-bus(PC98's legacy bus like ISA) network cards support.
Change IO port and IRQ assign.
Add New NE2000 compatible driver for PC-9800.
PCI netwwork card works fine without patch.

+
+ This driver should work with many programmed-I/O 8390-based ethernet
+ boards. Currently it supports the NE1000, NE2000, many clones,
+ and some Cabletron products.
+
+ Changelog:
+
+ Paul Gortmaker : use ENISR_RDC to monitor Tx PIO uploads, made
+ sanity checks and bad clone support optional.
+ Paul Gortmaker : new reset code, reset card after probe at boot.
+ Paul Gortmaker : multiple card support for module users.
+ Paul Gortmaker : Support for PCI ne2k clones, similar to lance.c
+ Paul Gortmaker : Allow users with bad cards to avoid full probe.
+ Paul Gortmaker : PCI probe changes, more PCI cards supported.
+ [email protected] : Changed init order so an interrupt will only
+ occur after memory is allocated for dev->priv. Deallocated memory
+ last in cleanup_modue()
+ Richard Guenther : Added support for ISAPnP cards
+ Paul Gortmaker : Discontinued PCI support - use ne2k-pci.c instead.
+ Osamu Tomita : Separate driver for NEC PC-9800.

+ NEx000-clone boards have a Station Address PROM (SAPROM) in the packet

+ the SAPROM, while other supposed NE2000 clones must be detected by their

+
+ Reading the SAPROM from a word-wide card with the 8390 set in byte-wide

+
+ The probe is also responsible for initializing the card and filling
+ in the 'dev' and 'ei_status' structures.
+
+ We use the minimum memory size for some ethercard product lines, iff we can't
+ distinguish models. You can increase the packet buffer size by setting
+ PACKETBUF_MEMSIZE. Reported Cabletron packet buffer locations are:
+ E1010 starts at 0x100 and ends at 0x2000.
+ E1010-x starts at 0x100 and ends at 0x8000. ("-x" means "more memory")

I suppose the first thing to point out is that it would be helpful if
you could send this to [email protected]. Although most SCSI
people also read linux-kernel, it is easy to lose things in the noise.

You already have the pc98_bios_param as part of your local driver. Why
do you need this in addition?

This really doesn't look right. For non PIO (which is all drivers apart
from yours), they expect to dereference SASR to get the port number (as
an unsigned char). If you remove the dereference, don't they all break?
Perhaps the better thing to do is to make your driver use an unsigned
int *, so the dereference works in all cases.

On m68k and MIPS, we do not derefence SASR to get the port number, SASR _is_
the MMIO pointer to the 8-bit SASR register. Hence you access the register by
dereferencing the pointer.

Actually, it was my suggestion to remove the dereference for PIO accesses. In
that case SASR contains the I/O port register.

There's still something wrong with the implementation in this patch.
For non PIO SASR is defined as volatile unsigned char *SASR. Its access
has gone from being outb(n, *regs.SASR) to outb(n, regs.SASR). What
expansion can outb have on m68k and MIPS that makes this change
idempotent?

outb() and friends are only used if CONFIG_WD33C93_PIO is set. In all other
cases, it uses the old implementation, e.g. `*regs.SASR = reg_num'.

Ah, OK, I see what it's doing. Instead of having a single redefine of
wd33c93_outb to be either outb or readb etc, it has a whole chunk of
code in wd33c93.c that #ifdef's for this.
Perhaps, while you're cleaning this up, you'd like to move this into the
header? Shouldn't it also be using readb/writeb instead of just direct
memory accesses?

We need this for other SCSI cards not only wd33c93. For example, we
have cards for PC98 that use aha152x, aic7xxx, advansys and sym53c8xx
drivers.
PC98 architecture has own boot selector and can boot any of 16 partitions
per 1 drive. The partition table conatins C/H/S geometry. And we can
assign non zero head or sector. Boot selector reads the partition table
and call BIOS by C/H/S parameters on boottime. If geometry is not mach
to BIOS, cannot boot from the partition created on linux.

I supposed, I use this patch with "#ifdef CONFIG_WD33C93_PIO" in
wd33c98.c.

No, readb() and friends are not defined on machines that don't have PCI. None
of the MMIO wd33c93 drivers are PCI.
However, it's fine for me to use in_8(addr) and out_8(addr,b) (cfr.
include/asm-m68k/raw_io.h) inside #if defined(__mc68000__) ||
defined(CONFIG_APUS).
On MIPS, it looks like you can use readb() and writeb(), since MIPS is less
picky than m68k about not defining PCI access primitives on machines without
PCI.
