The following driver provides complete interrupt-in and interrupt-out
reports (raw data) to a user program. Until now it uses the
HIDIOCGDEVINFO ioctl call, because I don't know better :-(. Perhaps, it
will be ok for you - and I will be happy, if you assign 8 minor numbers.
I have tested it in several environments and it works very well for me.
However, it has a problem with two or more devices at the same hub, if
the two or more devices need 1 ms interrupt-in transfers. Unfortunately
more than one interrupt-in transfer every ms isn't possible (ehci
driver?). This is why the min_interrupt_in_interval and
min_interrupt_out_interval are increased to 2 ms (see the corresponding
module parameters). This way, I can use two devices simultaneously at
the same hub.

Fixed three cases in the interpreter where an "index"
argument to an ASL function was still (internally) 32
bits instead of the required 64 bits. This was the Index
argument to the Index, Mid, and Match operators.
The "strupr" function is now permanently local
(acpi_ut_strupr), since this is not a POSIX-defined
function and not present in most kernel-level C
libraries. References to the C library strupr function
have been removed from the headers.
Completed the deployment of static
functions/prototypes. All prototypes with the static
attribute have been moved from the headers to the owning
C file.
ACPICA 20050329 from Bob Moore
An error is now generated if an attempt is made to create
a Buffer Field of length zero (A CreateField with a length
operand of zero.)
The interpreter now issues a warning whenever executable
code at the module level is detected during ACPI table
load. This will give some idea of the prevalence of this
type of code.
Implemented support for references to named objects (other
than control methods) within package objects.
Enhanced package object output for the debug
object. Package objects are now completely dumped, showing
all elements.
Enhanced miscellaneous object output for the debug
object. Any object can now be written to the debug object
(for example, a device object can be written, and the type
of the object will be displayed.)
The "static" qualifier has been added to all local
functions across the core subsystem.
The number of "long" lines (> 80 chars) within the source
has been significantly reduced, by about 1/3.
Cleaned up all header files to ensure that all CA/iASL
functions are prototyped (even static functions) and the
formatting is consistent.

acnames.h.

Implement the framework for binding physical devices
with ACPI devices. A physical bus like PCI bus
should create a 'acpi_bus_type', with:
.find_device:
For device which has parent such as normal PCI devices.
.find_bridge:
It's for special devices, such as PCI root bridge
or IDE controller. Such devices generally haven't a
parent or ->bus. We use the special method
to get an ACPI handle.

Here is a proposed Kconfig update for the new max6875 i2c chip driver.
Signed-off-by: Jean Delvare <khali@linux-fr.org>
Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
After a careful code analysis on the new max6875 driver
(drivers/i2c/chips/max6875.c), I have come to the conclusion that this
driver may cause EEPROM corruptions if used on random systems.
The EEPROM part of the MAX6875 chip is accessed using rather uncommon
I2C sequences. What is seen by the MAX6875 as reads can be seen by a
standard EEPROM (24C02) as writes. If you check the detection method
used by the driver, you'll find that the first SMBus command it will
send on the bus is i2c_smbus_write_byte_data(client, 0x80, 0x40). For
the MAX6875 it makes an internal pointer point to a specific offset of
the EEPROM waiting for a subsequent read command, so it's not an actual
data write operation, but for a standard EEPROM, this instead means
writing value 0x40 to offset 0x80. Blame Philips and Intel for the
obscure protocol.
Since the MAX6875 and the standard, common 24C02 EEPROMs share two I2C
addresses (0x50 and 0x52), loading the max6875 driver on a system with
standard EEPROMs at either address will trigger a write on these
EEPROMs, which will lead to their corruption if they happen not to be
write protected. This kind of EEPROMs can be found on memory modules
(SPD), ethernet adapters (MAC address), laptops (proprietary data) and
displays (EDID/DDC). Most of these are hopefully write-protected, but
not all of them.
For this reason, I would recommend that the max6875 driver be
neutralized, in a way that nobody can corrupt his/her EEPROMs by just
loading the driver. This means either deleting the driver completely, or
not listing any default address for it. I'd like this to be done before
2.6.13-rc1 is released.
Additionally, the max6875 driver lacks the 24RF08 corruption preventer
present in the eeprom driver, which means that loading this driver in a
system with such a chip would corrupt it as well.
Here is a proposed quick patch addressing the issue, although I wouldn't
mind a complete removal if it makes everyone feel safer. I think Ben
has plans to replace this driver by a much simplified one anyway.

Currently hid-core follows the same code path for input reports
regardless of whether they are a result of interrupt transfers or
control transfers. That leads to interrupt events erroneously being
reported to hiddev for regular control transfers.
Prior to 2.6.12 the problem was mitigated by the fact that
reporting to hiddev is supressed if the field value has not changed,
which is often the case. Said filtering was removed in 2.6.12-rc1 which
means any input reports fetched via control transfers result in hiddev
interrupt events. This behavior can quickly lead to a feedback loop
where a userspace app, in response to interrupt events, issues control
transfers which in turn create more interrupt events.
This patch prevents input reports that arrive via control transfers from
being reported to hiddev as interrupt events.

Lots of this patch is trivial code cleanups (static vars were being
intialized to 0, etc).
There's also some fixes for ISO transmits (max buffer handling).
Aswell, we have a few fixes to disable IRM capabilites correctly. We've
also disabled, by default some generally unused EXPORT symbols for the
sake of cleanliness in the kernel. However, instead of removing them
completely, we felt it necessary to have a config option that allowed
them to be enabled for the many projects outside of the main kernel tree
that use our API for driver development.
The primary reason for this patch is to revert a MODE6->MODE10 RBC
conversion patch from the SCSI maintainers. The new conversions handled
directly in the scsi layer do not seem to work for SBP2. This patch
reverts to our old working code so that users can enjoy using Firewire
disks and dvd drives again.
We are working with the SCSI maintainers to resolve this issue outside
of the main kernel tree. We'll merge the patch once the SCSI layer's
handling of the MODE10 conversion is working for us.

This is part of the grand scheme to eliminate the qlen
member of skb_queue_head, and subsequently remove the

Most users of skb_queue_len() want to know if the queue is
empty or not, and that's trivially done with skb_queue_empty()
which doesn't use the skb_queue_head->qlen member and instead
uses the queue list emptyness as the test.

The Linux PCMCIA code has some data that was apparently used (or meant to be
used) to ensure that only proper client drivers are loaded. This is now
ensured (to a certain degree) by the fact that the most client drivers are
part of the kernel. Also, the version information has not been updated
despite major changes in PCMCIA API. This has made it meaningless.
This patch removes servinfo_t and pcmcia_get_card_services_info. They are not
used in any userspace utilities such as pcmcia-cs and pcmciautils.
drivers/pcmcia/pcmcia_ioctl.c is adjusted accordingly.
CS_RELEASE and CS_RELEASE_CODE are removed. include/pcmcia/version.h is empty
now. It will be removed later, but for now it's left in the tree to avoid
touching all PCMCIA clients.
The only driver that needs to be changed is drivers/scsi/pcmcia/nsp_cs.c,
which uses CS_RELEASE_CODE.

converted the check_region() calls in drivers/pcmcia/i82365.c into
request_regions. Unfortunately this seems to have broken things.
isa_probe() used to call check_region() and then call add_pcic() which would
request_region().
Now isa_probe() calls request_region() and then calls add_pcic() which calls
request_region() again, this fails and add_pcic() returns immediately without
doing all the setup etc.
On the face of it the patch below fixes the problem, by not doing the second
request region in add_pcic(). I think this is preferable to remove the call
in isa_probe() since identify() touches the I/O regions and is called before
add_pcic().
However I haven't fully grokked the meaning of the code which follows the
request_region() in isa_probe(), so I'm not sure that the handling WRT
multiple sockets and multiple bridge chips is correct. In particular I'm not
convinced that the regions for subsequent sockets and/or bridges will be
requested at all. I suspect a more thorough reworking by someone who
understands what is going on there might be in order.
I should mention that I'm actually messing about with this on an ARM platform
with wacky memory and i/o mapping offsets etc, it doesn't quite work yet for
other reasons which preclude full testing etc, but I think the problem above
is still present for more normal x86 stuff.

First of a series of patches which add support for direct userspace access to
InfiniBand hardware -- so-called "userspace verbs." I believe these patches
are ready to merge, but a final review would be useful.
These patches should incorporate all of the feedback from the discussion when
I posted an earlier version back in April (see
http://lkml.org/lkml/2005/4/4/267 for the start of the thread). In
particular, memory pinned for use by userspace is accounted for in
current->mm->vm_locked and requests to pin memory are checked against
RLIMIT_MEMLOCK.
This patch:
Modify the ib_verbs.h header file with changes required for InfiniBand
userspace verbs support. We add a few structures to keep track of userspace
context, and extend the driver API so that low-level drivers know when they're
creating resources that will be used from userspace.

Add a new section called ".data.read_mostly" for data items that are read
frequently and rarely written to like cpumaps etc.
If these maps are placed in the .data section then these frequenly read
items may end up in cachelines with data is is frequently updated. In that
case all processors in an SMP system must needlessly reload the cachelines
again and again containing elements of those frequently used variables.
The ability to share these cachelines will allow each cpu in an SMP system
to keep local copies of those shared cachelines thereby optimizing
performance.

The patch fixes a few corner cases around tty line editing with
very long input lines:
- n_tty_receive_char(): don't simply drop eol characters,
otherwise canon_data isn't increased and the reader isn't woken
up.
- n_tty_receive_room(): If there is no newline pending and the
edit buffer is full, allow only a single character to be written
(until eol is found and the line is flushed), so characters from
the next line aren't dropped.
- write_chan(): if an incomplete line was written, continue
writing until write() returns 0, otherwise it might not write
the eol character to flush the line and the writer goes to sleep
without ever being woken up.
BTW the core problem is that part of this should be handled in the
receive_buf path, but for this it has to return the number of
written characters, as the amount of written characters may not be
the same as the amount of characters going into the write buffer,
so the receive_room() usage in pty_write() is not really reliable.
Alan said:
The problem looks valid. The behaviour of 'traditional unix' appears to
be the following
If you exceed the line limit then beep and drop the character
Always allow EOL to complete a canonical line input
Always do signal/control processing if enabled
