During cable pull tests on our 16G FC adapter, we are seeing errors,
typically reads to close targets, which fail due to CRC or framing
errors caused by the cable being pull (return status DID_ERROR).
The adapter detects the error on one of the first frames received,
marks the FC exchange as dead (further frames go to bit bucket) and
signals the host of the error. This action is so quick, and coupled
with fast host CPUs, creates a scenario in which the midlayer sees
the failure and retries the io almost immediately. We've seen link
traces with the retry on the link while the original i/o is still
being processed by the target. We're also seeing the time window
for the "link to pull-apart" and the physical interface to report
disconnected to be in the few millisecond range. Which means, we're
encountering scenarios where the full retry count is exhausted
(all with error) by the midlayer before the link disconnect state
is detected.
We looked at 8G FC behavior and occasionally see the same behavior,
but as the link was slower, it rarely could exhaust all retries
before the link reported disconnect.
What is needed is a slight delay between io retries due to DID_ERROR
to cover this error. It is inappropriate to put this delay in the
driver, as the error is indistinguishable from other link-related errors,
nor does the driver track whether the io is a retry or not. This is also
easier than tracking between-io-error bursts that are seen in this
scenario.
The patch below updates the retry path so that it inserts a delay as
if the target was busy. The busy delay is on the order of 6ms. This
delay is sufficient to ensure the link down condition is reported
before the retry count is exhausted (at most 1 retry is seen).

When parsing PnP ACPI resource structures, it may happen that some of
the resources are disabled (in which case "the size" of the resource
equals zero).
The current solution is to skip these resources completely - with the
unfortunate side effect that they are not registered despite the fact
that they exist, after all. (The downside of this approach is that
these resources cannot be used as templates for setting the actual
device's resources because they are missing from the template.) The
kernel's APM implementation does not suffer from this problem and
registers all resources regardless of "their size".
This patch fixes a problem with (at least) the vintage IBM ThinkPad 600E
(and most likely also with the 600, 600X, and 770X which have a very
similar layout) where some of its PnP devices support options where
either an IRQ, a DMA, or an IO port is disabled. Without this patch,
the devices can not be configured using the
"/sys/bus/pnp/devices/*/resources" interface.
The manipulation of these resources is important because the 600E has
very demanding requirements. For instance, the number of IRQs is not
sufficient to support all devices of the 600E. Fortunately, some of the
devices, like the sound card's MPU-401 UART, can be configured to not
use any IRQ, hence freeing an IRQ for a device that requires one.
(Still, the device's "ResourceTemplate" requires an IRQ resource
descriptor which cannot be created if the resource has not been
registered in the first place.)
As an example, the dependent sets of the 600E's CSC0103 device (the
MPU-401 UART) are listed, with the patch applied, as:
Dependent: 00 - Priority preferred
port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding
irq <none> High-Edge
Dependent: 01 - Priority acceptable
port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding
irq 5,7,2/9,10,11,15 High-Edge
(The same result is obtained when PNPBIOS is used instead of PnP ACPI.)
Without the patch, the IRQ resource in the preferred option is not
listed at all:
Dependent: 00 - Priority preferred
port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding
Dependent: 01 - Priority acceptable
port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding
irq 5,7,2/9,10,11,15 High-Edge
And in fact, the 600E's DSDT lists the disabled IRQ as an option, as can
be seen from the following excerpt from the DSDT:
Name (_PRS, ResourceTemplate ()
{
StartDependentFn (0x00, 0x00)
{
IO (Decode16, 0x0300, 0x0330, 0x10, 0x04)
IRQNoFlags () {}
}
StartDependentFn (0x01, 0x00)
{
IO (Decode16, 0x0300, 0x0330, 0x10, 0x04)
IRQNoFlags () {5,7,9,10,11,15}
}
EndDependentFn ()
})
With this patch applied, a user space program - or maybe even the kernel
- can allocate all devices' resources optimally. For the 600E, this
means to find optimal resources for (at least) the serial port, the
parallel port, the infrared port, the MWAVE modem, the sound card, and
the MPU-401 UART.
The patch applies the idea to register disabled resources to all types
of resources, not just to IRQs, DMAs, and IO ports. At the same time,
it mimics the behavior of the "pnp_assign_xxx" functions from
"drivers/pnp/manager.c" where resources with "no size" are considered
disabled.
No regressions were observed on hardware that does not require this
patch.
The patch is applied against 2.6.39.
NB: The kernel's current PnP interface does not allow for disabling individual
resources using the "/sys/bus/pnp/devices/$device/resources" file. Assuming
this could be done, a device could be configured to use a disabled resource
using a simple series of calls:
echo disable > /sys/bus/pnp/devices/$device/resources
echo clear > /sys/bus/pnp/devices/$device/resources
echo set irq disabled > /sys/bus/pnp/devices/$device/resources
echo fill > /sys/bus/pnp/devices/$device/resources
echo activate > /sys/bus/pnp/devices/$device/resources
This patch addresses only the parsing of PnP ACPI devices.
