ATA devices don't generate many errors, so the preferred method is to
printk() when they occur.
ATAPI devices generate tons of exceptions during the normal course
of operation, so this change skips logging the most common class of
errors.
The following code segment is not functional because the transfer cycle time speficied by
the EIDE device is later overwritten by ata_timing_quantize():
/*
* If the drive is an EIDE drive, it can tell us it needs extended
* PIO/MW_DMA cycle timing.
*/
if (adev->id[ATA_ID_FIELD_VALID] & 2) { /* EIDE drive */
memset(&p, 0, sizeof(p));
(snip)
ata_timing_merge(&p, t, t, ATA_TIMING_CYCLE | ATA_TIMING_CYC8B);
<== uninitialized "t" is used here
}
/*
* Convert the timing to bus clock counts.
*/
ata_timing_quantize(s, t, T, UT); <== t is overwritten by quantized s
The patch has been submitted for ide-timing.h before:
http://marc.theaimsgroup.com/?l=linux-ide&m=110820013425454&w=2
Resubmitted for libata.
Changes:
- Minor fix to honor the following transfer cycle time speficied by the device
- id[65]: Minimum Multiword DMA transfer cycle time per word
- id[67]: Minimum PIO transfer cycle time without flow control
- id[68]: Minimum PIO transfer cycle time with IORDY

- Move ATAPI check-condition handling out of the timeout handler
- Use multi-qc-issue feature to issue REQUEST SENSE ATAPI PACKET
command upon receiving an ATAPI check-condition.
This cleans things up a lot, and eliminates a nasty recursion bug.
- in ata_dev_identify(), don't assume that all devices are either
ATA or ATAPI. In the future, this code will see port multipliers
and other devices.
- make a debugging printk less verbose
- add new helper ata_qc_reinit()
- add new helper BPRINTK() and port flag ATA_FLAG_DEBUGMSG, for
fine-grained debugging use.
The ATAPI pad-to-next-32bit-boundary code modifies the scatterlist's
length variable, sometimes to zero. x86-64 platform would oops if a
zero-length scatterlist entry was asked to be mapped. Work around this
by ensuring that we never DMA-map a zero length buffer or SG entry.
Needed to get ATAPI working.
- dump hardware error bits, if hardware signals an error
- only reset hardware during timeout if a command was active
- call ata_qc_complete() with a fine-grained error mask.
Needed so that atapi_qc_complete() can distinguish between
device errors and other errors.

xscale-type UARTs have an extra bit (UUE) in the IER register that has
to be written as 1 to enable the UART. At the end of autoconfig() in
drivers/serial/8250.c, the IER register is unconditionally written as
zero, which turns off the UART, and makes any subsequent printch() hang
the box.
Since other 8250-type UARTs don't have this enable bit and are thus
always 'enabled' in this sense, it can't hurt to enable xscale-type
serial ports all the time as well. The attached patch changes the
autoconfig() exit path to see if the port has an UUE enable bit, and if
yes, to write UUE=1 instead of just putting a zero into IER, using the
same test as is used at the beginning of serial8250_console_write().

We had similar problems with other ioctls where userspace did things
like that. What we did there was to put the compat handler to generic
code. The patch below does that, adding a big comment about what's

MSI hardcoded delivery mode to use logical delivery mode. Recently
x86_64 moved to use physical mode addressing to support physflat mode.
With this mode enabled noticed that my eth with MSI werent working.
msi_address_init() was hardcoded to use logical mode for i386 and x86_64.
So when we switch to use physical mode, things stopped working.
Since anyway we dont use lowest priority delivery with MSI, its always
directed to just a single CPU. Its safe and simpler to use
physical mode always, even when we use logical delivery mode for IPI's
or other ioapic RTE's.

This patch further tweaks how we request control of hotplug
controller hardware from BIOS. We first search the ACPI namespace
corresponding to a specific hotplug controller looking for an
_OSC or OSHP method. On failure, we successively move to the
ACPI parent object, till we hit the highest level host bridge
in the hierarchy. This allows for different types of BIOS's
which place the _OSC/OSHP methods at various places in the acpi
namespace, while still not encroaching on the namespace of
some other root level host bridge.
This patch also introduces a new load time option (pciehp_force)
that allows us to bypass all _OSC/OSHP checking. Not supporting
these methods seems to be be the most common ACPI firmware problem
we've run into. This will still _not_ allow the pciehp driver to
work correctly if the BIOS really doesn't support pciehp (i.e. if
it doesn't generate a hotplug interrupt). Use this option with
caution. Some BIOS's may deliberately not build any _OSC/OSHP
methods to make sure it retains control the hotplug hardware.
Using the pciehp_force parameter for such systems can lead to
two separate entities trying to control the same hardware.

This patch tweaks the way pciehp requests control of the hotplug
hardware from BIOS. It now tries to invoke the ACPI _OSC method
for a specific hotplug controller only, rather than walking the
entire acpi namespace invoking all possible _OSC methods under
all host bridges. This allows us to gain control of each hotplug
controller individually, even if BIOS fails to give us control of
some other hotplug controller in the system.

Reduce the PCI Express hotplug driver's dependence on ACPI.
We don't walk the acpi namespace anymore to build a list of
bridges and devices. We go to ACPI only to run the _OSC or
_OSHP methods to transition control of hotplug hardware from
system BIOS to the hotplug driver, and to run the _HPP
method to get hotplug device parameters like cache line size,
latency timer and SERR/PERR enable from BIOS.
Note that one of the side effects of this patch is that pciehp
does not automatically enable the hot-added device or its DMA
bus mastering capability now. It expects the device driver to
do that. This may break some drivers and we will have to fix
them as they are reported.

Some devices have more than one capability of the same type. For
example, the PCI header for the PathScale InfiniPath looks like:
04:01.0 InfiniBand: Unknown device 1fc1:000d (rev 02)
Subsystem: Unknown device 1fc1:000d
Flags: bus master, fast devsel, latency 0, IRQ 193
Memory at fea00000 (64-bit, non-prefetchable) [size=2M]
Capabilities: [c0] HyperTransport: Slave or Primary Interface
Capabilities: [f8] HyperTransport: Interrupt Discovery and Configuration
There are _two_ HyperTransport capabilities, and the PathScale driver
wants to look at both of them.
The current pci_find_capability() API doesn't work for this, since it
only allows us to get to the first capability of a given type. The
patch below introduces a new pci_find_next_capability(), which can be
used in a loop like
for (pos = pci_find_capability(pdev, <ID>);
pos;
pos = pci_find_next_capability(pdev, pos, <ID>)) {
/* ... */

Patch from Richard Purdie
This patch adds a power and battery management core driver which with
the addition of the right device files, supports the c7x0 and cxx00
series of Sharp Zaurus handhelds.
The driver is complex for several reasons. Battery charging is manually
monitored and controlled. When suspended, the device needs to
periodically partially resume, check the charging status and then
re-suspend. It does without bothering the higher linux layers as
a full resume and re-suspend is unnecessary. The code is carefully
written to avoid interrupts or calling code outside the module under
these circumstances. It also vets the various wake up sources and
monitors the device's power situation.
Hooks to limit the backlight intensity and to notify the battery
monitoring code of backlight events are connected/added as the
backlight is one of the biggest users of power on the device.
