The following change from -mm is important to 2.6.18 (actually to 2.6.17
but its too late for that). This was contributed over three months ago
by VIA to Bartlomiej and nothing happened. As a result the new chipset
is now out and Linux won't run on it. By the time 2.6.18 is finalised
this will be the defacto standard VIA chipset so support would be a good
plan.
Tested in -mm for a while, its essentially a PCI ident update but for
the bridge chip because VIA do things in weird ways.

Prior to 2.6.18rc1 you could install with devices on a JMicron chipset
using the "all-generic-ide" option. As of this kernel the AHCI driver
grabs the controller and rams it into AHCI mode losing the PATA ports
and making CD drives and the like vanish. The all-generic-ide option
fails because the AHCI driver grabbed the PCI device and reconfigured
it.
To fix this three things are needed.
#1 We must put the chip into dual function mode
#2 The AHCI driver must grab only function 0 (already in your rc1 tree)
#3 Something must grab the PATA ports
The attached patch is the minimal risk edition of this. It puts the chip
into dual function mode so that AHCI will grab the SATA ports without
losing the PATA ports. To keep the risk as low as possible the third
patch adds the PCI identifiers for the PATA port and the FN check to the
ide-generic driver. There is a more featured jmicron driver on its way
but that adds risk and the ide-generic support is sufficient to install
and run a system.
The actual chip setup done by the quirk is the precise setup recommended
by the vendor.
(The JMB368 appears only in the ide-generic entry as it has no AHCI so
does not need the quirk)

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.

quantizing the ide_timing[] entry, instead of copying from that entry to

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

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.

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
any setup of their own before calling ide_setup_ports().

I have seen the cdrom drive appearing confused on using kdump on certain
x86_64 systems. During the booting up of the second kernel, the following
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.

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).

Instead of the two status values struct pcmcia_device->p_state and state,

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

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.

I just purchased a HighPoint Rocket 1520 SATA controller. There seems to
be no libata driver (yet), but there is an ide driver, hpt366. When the
driver gets loaded, it causes a kernel NULL pointer dereference in
pci_bus_clock_list. It seems to be because the driver is waiting for clock
stabilization in init_hpt37x() which never comes. The driver just
continues on with the pci drvdata set to NULL, instead of a valid clock
entry. The following patch prevents the NULL dereference from happening,
but instead exit with an error.

This patch stops CompactFlash devices being marked as removable. They are
not removable (as defined by Linux) as the media and device are
inseparable. When a card is removed, the whole device is removed from the
system and never sits in a media-less state.

Further, once this change is made, there is no need for ide to can be
