Driver core: bus: remove indentation level

Before potentially fixing up these functions, this cosmetic change
reduces the indentation level to make the code easier to read and
maintain.

No functional changes at all.

Alan Stern [Thu, 5 Oct 2006 21:03:24 +0000]
Driver core: Don't ignore error returns from probing

This patch (as797) fixes device_add() in the driver core.  It needs to
pay attention when the driver for a new device reports an error.

At the same time, since bus_remove_device() undoes the effects of both
bus_add_device() and bus_attach_device(), it needs to check whether
the bus_attach_device step failed.

David S. Miller [Wed, 18 Oct 2006 02:04:44 +0000]
[SPARC64]: Fix PCI memory space root resource on Hummingbird.

For Hummingbird PCI controllers, we should create the root
PCI memory space resource as the full 4GB area, and then
allocate the IOMMU DMA translation window out of there.

The old code just assumed that the IOMMU DMA translation base
to the top of the 4GB area was unusable.  This is not true on
many systems such as SB100 and SB150, where the IOMMU DMA
translation window sits at 0xc0000000->0xdfffffff.

So what would happen is that any device mapped by the firmware
at the top section 0xe0000000->0xffffffff would get remapped
by Linux somewhere else leading to all kinds of problems and
boot failures.

While we're here, report more cases of OBP resource assignment
conflicts.  The only truly valid ones are ROM resource conflicts.

USB: xpad: dance pad support

Adds support for dance pads to the xpad driver. Dance pads require the
d-pad to be mapped to four buttons instead of two axes, so that
combinations of up/down and left/right can be hit simultaneously.
Known dance pads are detected, and there is a module parameter added
to default unknown xpad devices to map the d-pad to buttons if this is
desired. (dpad_to_buttons). Minor modifications were made to port the
changes in the original patch to a newer kernel version.

This patch was originally from Dominic Cerquetti originally written
for kernel 2.6.11.4, with minor modifications (API changes for USB,
spelling fixes to the documentation added in the original patch) made
to apply to the current kernel. I have modified Dominic's original
patch per some suggestions from Dmitry Torokhov. (There was nothing
in the patch format description about multiple From: lines, so I
haven't added myself.)

12 years agoUSB: input: extract() and implement() are bit field manipulation routines
Grant Grundler [Tue, 10 Oct 2006 21:42:51 +0000]
USB: input: extract() and implement() are bit field manipulation routines

extract() and implement() have brain damaged attempts to handle 32-bit wide
"fields".

The problem is the index math in the original code didn't clear all the
relevant bits.  (offset >> 5) only compensated for 32-bit index.  We need
(offset >> 6) if we want to use 64-bit loads.

But it was also wrong in that it tried to use quasi-aligned loads.  Ie
"report" was only incremented in multiples of 4 bytes and then the offset
was masked off for values greater than 4 bytes.  The right way is to
pretend "report" points at a byte array.  And offset is then only minor
adjustment for < 8 bits of offset.  "n" (field width) can then be as big as
24 (assuming 32-bit loads) since "offset" will never be bigger than 7.

If someone needs either function to handle more than 24-bits, please
document why - point at a specification or specific USB hid device - in
comments in the code.

extract/implement() are also an eyesore to read.  Please banish whoever
wrote it to read CodingStyle 3 times in a row to a classroom full of 1st
graders armed with rubberbands.  Or just flame them.  Whatever.  Globbing
all the code together on two lines does NOT make it faster and is Just
Wrong.

I've tested this patch on j6000 (dual 750Mhz PA-RISC, 32-bit 2.6.12-rc5).
Kyle McMartin tested on c3000 (up 400Mhz PA-RISC, same kernel).  "p2-mate"

usbnet: add a mutex around phy register access

When working on the mcs7830, I noticed the need for a mutex in its
mdio_read/mdio_write functions. A related problem seems to be present
in the asix driver in the respective functions.

This introduces a mutex in the common usbnet driver and uses it
from the two hardware specific drivers.

Arnd Bergmann [Sun, 8 Oct 2006 22:08:00 +0000]
USB: driver for mcs7830 (aka DeLOCK) USB ethernet adapter

This driver adds support for the DeLOCK USB ethernet adapter
and potentially others based on the MosChip MCS7830 chip.

It is based on the usbnet and asix drivers as well as the
original device driver provided by MosChip, which in turn
was based on the usbnet driver.

It has been tested successfully on an OHCI, but interestingly
there seems to be a problem with the mcs7830 when connected to
the ICH6/EHCI in my thinkpad: it keeps receiving lots of
broken packets in the RX interrupt. The problem goes away when
I'm using an active USB hub, so I assume it's not related to
the device driver, but rather to the hardware.

speedtch: "extended reach"

The speedtouch modem setup code was reverse engineered many years
ago from a prehistoric windows driver. Less ancient windows drivers,
even those from a few years ago, perform extra initialization steps
which this patch adds to the linux driver.  David Woodhouse observed
that this initialization along with the firmware bin/sachu3/zzzlp2.eni
from the driver at
http://www.speedtouch.co.uk/downloads/330/301/UK3012%20Extended.zip
improves line sync speeds by about 20%.  He provided the original
patch, which I've modified to use symbolic names (BMaxDSL, ModemMode,
ModemOption) rather than magic numbers.  These names may not seem like
much of an improvement (after all, what is "ModemOption" exactly?),
but they do have one big advantage: they are the names used in the
windows registry.  I've made them available as module parameters.
Thanks are due to Aurelio Arroyo, who noticed the relationship
between these magic numbers and the entries in Phonebook.ini.

12 years agosky2: no message on rx fifo overflow
Stephen Hemminger [Tue, 17 Oct 2006 17:24:16 +0000]
sky2: no message on rx fifo overflow

Under high load it is possible to make the receiver FIFO get overloaded.
The driver/hardware recover properly, so there is no reason to fill the log
with lots of extra messages, just update counter.

sky2: flow control setting fixes

The result of flow control negotiation should not limit the next
negotiatition. If board is plugged into an old half duplex 10Mbit port,
without pause, then replugged into a gigabit port, it should negotiate
what is desired, not inherit that last negotiation.

12 years ago[PATCH] ISDN: fix drivers, by handling errors thrown by ->readstat()
Jeff Garzik [Tue, 17 Oct 2006 07:10:39 +0000]
[PATCH] ISDN: fix drivers, by handling errors thrown by ->readstat()

This is a particularly ugly on-failure bug, possibly security, since the
lack of error handling here is covering up another class of bug: failure to
handle copy_to_user() return values.

The I4L API function ->readstat() returns an integer, and by looking at
several existing driver implementations, it is clear that a negative return
value was meant to indicate an error.

Given that several drivers already return a negative value indicating an
errno-style error, the current code would blindly accept that [negative]
value as a valid amount of bytes read.  Obvious damage ensues.

Correcting ->readstat() handling to properly notice errors fixes the
existing code to work correctly on error, and enables future patches to
more easily indicate errors during operation.

12 years ago[PATCH] Convert cpu hotplug notifiers to use raw_notifier instead of blocking_notifier
Neil Brown [Tue, 17 Oct 2006 07:10:35 +0000]
[PATCH] Convert cpu hotplug notifiers to use raw_notifier instead of blocking_notifier

The use of blocking notifier by _cpu_up and _cpu_down in cpu.c has two
problem.

1/ An interaction with the workqueue notifier causes lockdep to spit a
   warning.

2/ A notifier could conceivable be added or removed while _cpu_up or
   _cpu_down are in process.  As each notifier is called twice (prepare
   then commit/abort) this could be unhealthy.

To fix to we simply take cpu_add_remove_lock while adding or removing
notifiers to/from the list.

This makes the 'blocking' usage unnecessary as all accesses to cpu_chain
are now protected by cpu_add_remove_lock.  So change "blocking" to "raw" in
all relevant places.  This fixes 1.
