The newly released HID protocol for win8 multitouch devices is capable
of transmitting more information about each touch. In particular, it
includes details useful for touch alignment. This patch completes the
MT protocol with the ABS_MT_TOOL_X/Y events, and documents how to map
win8 devices.

The normal messages sent after boot or NVRAM update are T6 reports,

Each interrupt contains information for all contacts with changing
properties. Process all of this information at once, and send it all in a
a single input report (ie input events ending in EV_SYN/SYN_REPORT).

Atmel mxt devices can report one finger for each T9 reportid.
Therefore, this range can be used to report the max number of MT-B slots
to userspace instead of assuming a fixed 10.
Note that mxt_initialized() must complete early, since the input_dev
properties now depend on values in the object table.

Streamline interrupt processing by caching the T9 reportid range when
first reading the object table.
In the process, refactor reading the object descriptor table.
First, since the object_table entries are now exactly the same layout
in device memory and in the driver, allocate an appropriately sized
array and fetch the entire table directly into it in a single i2c
transaction. Since a 6 byte table object requires 10 bytes to read,
doing this dramatically reduces overhead.
Note: The cached T9 reportid's are initialized to 0, which is an invalid
reportid. Thus, the checks in the interrupt handler will always fail for
devices that do not support the T9 object. Therefore, after doing a
firmware update, the old object table is destroyed and all cached object
values are reset to 0, before reading the new object table, in case
the new firmware does not have the old objects.
This patch tested on an MXT224E.

The Object Table is freed in three cases:
1) When the driver is being removed.
2) In the error path of mxt_initialize().
3) Just after a firmware update, when a new object table is
about to be read.
For cases 2 & 3, the driver is not immediately unloaded, so this patch
refactors these cases to use a common cleanup function. It also refactors
the mxt_initialize error paths to ensure that this cleanup happens.
Note: mxt_update_fw_store() does not handle errors during mxt_initialize().
A proposed fix for this is in a subsequent patchset.

Instead of carrying around per-finger state in the driver instance, just
report each finger as it arrives to the input layer, and let the input
layer (evdev) hold the event state (which it does anyway).
Note: this driver does not really do MT-B properly. Each input report
(a group of input events followed by a SYN_REPORT) only contains data for
a single contact. When multiple fingers are present on a device, each is
properly reported in its own MT_SLOT. However, there is only ever one
MT_SLOT per SYN_REPORT. This is fixed in a subsequent patch.
This patch was tested with an mXT224E.

The i2c bus requires 4 bytes to do a 1-byte write
(1 byte i2c address + 2 byte offset + 1 byte data).
By taking a length with writes, the driver can amortize transaction
overhead by performing larger transactions where appropriate.
This patch just sets up the new API. Later patches refactor writes
to take advantage of the larger transactions.

Pull device-mapper updates from Alasdair G Kergon:
"Improve multipath's retrying mechanism in some defined circumstances
and provide a simple reserve/release mechanism for userspace tools to
access thin provisioning metadata while the pool is in use."
* tag 'dm-3.5-changes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm:
dm thin: provide userspace access to pool metadata
dm thin: use slab mempools
dm mpath: allow ioctls to trigger pg init
dm mpath: delay retry of bypassed pg
dm mpath: reduce size of struct multipath
|
|
This patch implements two new messages that can be sent to the thin
pool target allowing it to take a snapshot of the _metadata_. This,
read-only snapshot can be accessed by userland, concurrently with the
live target.
Only one metadata snapshot can be held at a time. The pool's status
line will give the block location for the current msnap.
Since version 0.1.5 of the userland thin provisioning tools, the
thin_dump program displays the msnap as follows:
thin_dump -m <msnap root> <metadata dev>
Available here: https://github.com/jthornber/thin-provisioning-tools
Now that userland can access the metadata we can do various things
that have traditionally been kernel side tasks:
i) Incremental backups.
By using metadata snapshots we can work out what blocks have
changed over time. Combined with data snapshots we can ensure
the data doesn't change while we back it up.
A short proof of concept script can be found here:
https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb
ii) Migration of thin devices from one pool to another.
iii) Merging snapshots back into an external origin.
iv) Asyncronous replication.

After the failure of a group of paths, any alternative paths that
need initialising do not become available until further I/O is sent to
the device. Until this has happened, ioctls return -EAGAIN.
With this patch, new paths are made available in response to an ioctl
too. The processing of the ioctl gets delayed until this has happened.
Instead of returning an error, we submit a work item to kmultipathd
(that will potentially activate the new path) and retry in ten
milliseconds.
Note that the patch doesn't retry an ioctl if the ioctl itself fails due
to a path failure. Such retries should be handled intelligently by the
code that generated the ioctl in the first place, noting that some SCSI
commands should not be retried because they are not idempotent (XOR write
commands). For commands that could be retried, there is a danger that
if the device rejected the SCSI command, the path could be errorneously
marked as failed, and the request would be retried on another path which
might fail too. It can be determined if the failure happens on the
device or on the SCSI controller, but there is no guarantee that all
SCSI drivers set these flags correctly.

If I/O needs retrying and only bypassed priority groups are available,
set the pg_init_delay_retry flag to wait before retrying.
If, for example, the reason for the bypass is that the controller is
getting reset or there is a firmware upgrade happening, retrying right
away would cause a flood of log messages and retries for what could be a
few seconds or even several minutes.

The config options in the Kconfig file (with _CODEPAGE_ in the name)

them hard to parse for normal humans: MACROMAN easily reads as "macro
man", not as "Mac Roman".
So rename the options to be consistent, and be NLS_MAC_xyzzy. Rename
the files to be mac-xyzzy.c too, and drop the "nls" part entirely (it's
already in the directory name).
