in ide_dump_opcode() takes the ide_lock in an irq-unsafe manner, i.e. this
function expects to be called with irqs disabled. But
ide_dump_ata[pi]_status() doesnt do that - it enables interrupts specifically.
That is a no-no - what guarantees that another IDE port couldnt generate an
IDE interrupt while we are dumping this error? The fix is to turn the
irq-enabling in these functions into irq-disabling.

Remove the busproc from pdc202xx_old.c because:
- it handles the obsolete HDIO_TRISTATE_HWIF ioctl instead of the modern
HDIO_SET_BUSSTATE, so treats its argument wrong;
- I don't think that tristating both channels is good idea (probably can't
be done otherwise since there seems to be only single bit controlling this).

The function ide_timing_compute() fails to *actually* take drive's
specified minimum PIO/DMA cycle times into account -- when doing this, it
calls ide_timing_merge() on the 'struct ide_timing' argument which contains
garbage at the moment, and then ultimately destroys the read cycle time by
quantizing the ide_timing[] entry, instead of copying from that entry to
the argument structure, and only then doing a merge/quantize.

This is a patch from Alan that fixes a real ide-cd.c regression causing
bogus "Media Check" failures for perfectly valid Fedora install ISOs, on
certain CD-ROM drives.
This is a forward port to 2.6.16 (from RHEL) of the minimal changes for the
end of media problem. It may not be sufficient for some controllers
(promise notably) and it does not touch the locking so the error path
locking is as horked as in mainstream.
From: Ingo Molnar <mingo@elte.hu>
I have ported the patch to 2.6.17-rc4 and tested it by provoking
end-of-media IO errors with an unaligned ISO image. Unlike the vanilla
kernel, the patched kernel interpreted the error condition correctly with
512 byte granularity:
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
ATAPI device hdc:
Error: Illegal request -- (Sense key=0x05)
Illegal mode for this track or incompatible medium -- (asc=0x64, ascq=0x00)
The failed "Read 10" packet command was:
"28 00 00 04 fb 78 00 00 06 00 00 00 00 00 00 00 "
end_request: I/O error, dev hdc, sector 1306080
Buffer I/O error on device hdc, logical block 163260
Buffer I/O error on device hdc, logical block 163261
Buffer I/O error on device hdc, logical block 163262
the unpatched kernel produces an incorrect error dump:
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1306080
Buffer I/O error on device hdc, logical block 163260
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1306088
Buffer I/O error on device hdc, logical block 163261
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1306096
Buffer I/O error on device hdc, logical block 163262
I do not have the right type of CD-ROM drive to reproduce the end-of-media
data corruption bug myself, but this same patch in RHEL solved it.

In both the read and write cases it will return an error if
copy_{from/to}_user faults. However, I let the driver try to read/write as
much as it can just as it normally would , then finally it returns an error
if there was one. This was the most straight forward way to handle the
error , since there isn't a clear way to clean up the buffers on error .
I moved retval in idetape_chrdev_write() down into the actual code blocks
since it's really once used there, and it conflicted with my ret variable.
Fixes the following warning,
drivers/ide/ide-tape.c: In function âidetape_copy_stage_from_userâ:
drivers/ide/ide-tape.c:2662: warning: ignoring return value of âcopy_from_userâ, declared with attribute warn_unused_result

ide_setup_ports does not completely initialize the hw_regs_t structure which
can cause random failures, as the structure is often on the stack. None of
the callers expect a partially initialized structure, i.e. none of them do

I have seen the cdrom drive appearing confused on using kdump on certain

message would keep flooding the console, and the booting would not proceed
any further.
hda: cdrom_pc_intr: The drive appears confused (ireason = 0x01)
In this patch, whenever we are hitting a confused state in the interrupt
handler with the DRQ set, we end the request and return ide_stopped. Using
this I dont see the status error.

This ugly hack was long overdue to die.
It was a way to print out Sparc interrupts in a more freindly format,
since IRQ numbers were arbitrary opaque 32-bit integers which vectored
into PIL levels. These 32-bit integers were not necessarily in the
0-->NR_IRQS range, but the PILs they vectored to were.
The idea now is that we will increase NR_IRQS a little bit and use a
virtual<-->real IRQ number mapping scheme similar to PowerPC.
That makes this IRQ printing hack irrelevant, and furthermore only a
handful of drivers actually used __irq_itoa() making it even less
useful.

From: Jeremy Higdon <jeremy@sgi.com>
This patch fixes a bug in sgiioc4 where it was using the default IDE port
I/O operations instead of MMIO.
The IDE part of the IOC4 chip uses MMIO to map the chip registers.
Unfortunately, the sgiioc4 driver uses the default port IO operations,
which happens to have worked for the past few years. That's about to
change, however, thus this change from inX/outX to readX/writeX.

It looks like the generic ide code now wants ide_init_hwif_ports() to set
the parent struct device into the ide_hw structure (new field ?). Without
this, the mac ide code can cause the ide probing code to explode in flames
in sysfs registration due to what looks like a stale pointer in there
(happens when removing/re-inserting one of the hotswap media bays on some
laptops).

Some quick backport bits from the libata PATA work to fix things found in
the sis driver. The piix driver needs some fixes too but those are way to
large and need someone working on old IDE with time to do them.
This patch fixes the case where random bits get loaded into SIS timing
registers according to the description of the correct behaviour from
Vojtech Pavlik. It also adds the SiS5517 ATA16 chipset which is not
currently supported by the driver. Thanks to Conrad Harriss for loaning me

AMD756 doesn't support host side cable detection. Do disk side only and
don't advice obsolete options.

This removes statically assigned platform numbers and reworks the
powerpc platform probe code to use a better mechanism. With this,
board support files can simply declare a new machine type with a
macro, and implement a probe() function that uses the flattened
device-tree to detect if they apply for a given machine.
We now have a machine_is() macro that replaces the comparisons of
_machine with the various PLATFORM_* constants. This commit also
changes various drivers to use the new macro instead of looking at
_machine.

Some drives like to throw a:
ATAPI device hdc:
Error: Not ready -- (Sense key=0x02)
Incompatible medium installed -- (asc=0x30, ascq=0x00)
The failed "Read Cd/Dvd Capacity" packet command was:
"25 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 "
warning on incompatible media, so quiet down this error.

In latest -mm ide-code.o gave a number of warnings like the following:
WARNING: drivers/ide/ide-core.o - Section mismatch: reference to \
.init.text: from .text between 'init_module' (at offset 0x1f97) and \
'cleanup_module'
The warning was caused by init_module() calling parse_option() and
ide_init() both declared __init.
Declaring init_module() __init fixes the warnings.

In some embedded systems the IDE hardware interface may only support 16-bit
or smaller accesses. Allow the interface to specify if this is the case
and don't allow the drive or user to override the setting.

Since early 2.4.x all cdrom drivers implement the block_device methods
themselves, so they can handle additional ioctls directly instead of going
through the cdrom layer.
