11 years agoHID: add hidraw interface
Jiri Kosina [Mon, 14 May 2007 07:57:40 +0000]
HID: add hidraw interface

hidraw is an interface that is going to obsolete hiddev one
day.

Many userland applications are using libusb instead of using
kernel-provided hiddev interface. This is caused by various
reasons - the HID parser in kernel doesn't handle all the
HID hardware on the planet properly, some devices might require
its own specific quirks/drivers, etc.

hiddev interface tries to do its best to parse all the received
reports properly, and presents only parsed usages into userspace.
This is however often not enough, and that's the reason why
many userland applications just don't use hiddev at all, and
rather use libusb to read raw USB events and process them on
their own.

Another drawback of hiddev is that it is USB-specific.

hidraw interface provides userspace readers with really raw HID
reports, no matter what the low-level transport layer is (USB/BT),
and gives the userland applications all the freedom to process
the HID reports in a way they wish to.

HID: enable hiddev for the SantaRosa MacBookPro IR receiver

The infrared remote receiver found in the SantaRosa MacBookPro
laptops (MacBookPro3,1) need to be forced to expose a HIDDEV
interface (instead of HIDINPUT) so that lirc can access it using
the 'macmini' driver.

The patch below adds the required quirk for forcing the HIDDEV
interface to be activated (HID_QUIRK_HIDDEV) and introduces a new
quirk which forces the HIDINPUT interface to be ignored
(HID_QUIRK_IGNORE_HIDINPUT).

Note that Apple calls this receiver 'IRController4' (info taken
from Apple's driver Info.plist). Older Mac{Book,Mini,Pro}s seem
to all use the 'IRController1' device (USB id 05ac:8240) which

HID: Report usage codes of keys as EV_MSC scancode events

Current HID layer does not report usage codes to the input layer. This feature
was previously removed, because it caused unnecessary storm of events in cases
of positioning devices, etc.

This patch adds reporting of usage codes as EV_MSC events only for key events.
We issue the EV_MSC event only if the state of the key corresponding to the
given code has changed, so that we don't report usages that are sent in every
report even if the state hasn't changed (for example Shift/Caps Lock/...
states as sent by various keyboards).

This functionality is required at least by KeyTouch in order to provide
convenient means for remapping the usage codes.

UBI: fix atomic LEB change problems

When the UBI device is nearly full, i.e. all LEBs are mapped, we have
only one spare LEB left - the one we reserved for WL purposes. Well,
I do not count the LEBs which were reserved for bad PEB handling -
suppose NOR flash for simplicity. If an "atomic LEB change operation"
is run, and the WL unit is moving a LEB, we have no spare LEBs to
finish the operation and fail, which is not good. Moreover, if there
are 2 or more simultanious "atomic LEB change" requests, only one of
them has chances to succeed, the other will fail with -ENOSPC. Not
good either.

This patch does 2 things:
1. Reserves one PEB for the "atomic LEB change" operation.
2. Serealize the operations so that only on of them may run
   at a time (by means of a mutex).

David S. Miller [Sun, 14 Oct 2007 04:51:37 +0000]
[SPARC64]: Use sun4v VIRQ interfaces as intended.

We were simply concatenating the devhandle and devino and using that
as the cookie, which defeats the entire purpose of the VIRQ hypervisor
interfaces.

Now that we use physical addresses for the INO buckets, we can
allocate them dynamically for VIRQs and encode the cookies as
~__pa(bucket).  This allows us to test for and decode the cookie with
a simple:

brlz $reg1, 1f
 xnor $reg1, %g0, $reg2

sequence.

This works because bit 64 is never set in traditional
INO vectors, and it is also never set in a physical
address.  So xnor'ing the physical address of the bucket
always gives us a negative number, and thus a unique
condition we can test cheaply.

Inspired by ideas from Greg Onufer.

[SPARC64]: Enable MSI on sun4u Fire PCI-E controllers.

The support code is identical to the hypervisor sun4v stuff,
just replacing the hypervisor calls with register reads and
writes in the Fire controller.

i2c-nforce2: Abort the transaction on error

This patch is to add an abort function that will bring back the MCP51/55
controller if it was blocked by a block-read operation, in particular.
(When a slave sends a wrong byte count on a byte read, the host gets
locked up). I've only tested it on an MCP51 and MCP55. However, I'm
almost certain it will also work on MCP65, I just did not have the board
to test it on. Thus for now the abort function will only be called
if an MCP51/55 was detected.

i2c-nforce2: Move status checking to a separate function

This is the first part of the patch that adds a function to reset the
nvidia MCP51/55 i2c controller, if something bad happens to it (e.g.
a slave sends a wrong byte count during a block transaction).

This patch just adds nforce2_check_status function. It was originally
written by Hans-Frieder Vogt.

The reason that I'm the one sending it is:
- I relied on it for the second part of the patch,
- It makes the driver code cleaner/better.

i2c-au1550: Fix a misused register problem

Fix a "mis-used register" problem on the AMD MIPS Alchemy au1550
I2C interface.

In summary, the programmable serial controller seems to hang the kernel
when I send a single 'address' byte on the I2C bus.  The patch
essentially uses the PSC_SMBSTAT register's TE (transmit FIFO empty)
bit to check when the transmit FIFO is empty, instead of using the
PSC_SMBEVNT register's TU (transmit underflow) bit.  Using the TE bit
fixed the hang problem.

i2c: Remove i2c_algorithm.algo_control()

This removes:

 - An effectively unused hook:  i2c_algorithm.algo_control.

 - The i2c_control() call, used only by i2c-dev to call that
   unused hook or set two barely supported adapter params.

   (That param setting moves into i2c-dev.c ... still iffy
   due to lack of locking, but no other changes.)

As shown by diffstat, this is a net code shrink.  It also reduces the
complexity of the I2C adapter and /dev interfaces.
