PATCH-9_9-gta01-Tweak-pixclock-to-reduce-flicker-with-cpufreq.eml
Experimenting with a GTA01 showed pixclock values near 40000 (after the
rounding caused by the divider calculation) caused visible flicker. Values
near 20000 caused only a slight flicker, and the default value after rounding
with the default HCLK frequency of 133MHz is 30075.
Change the value to 35000 to make it stay in the range 17500-35000 and thus
reduce the flicker a bit.

Thanks for the pointer! Interesting reading.
So this is a 2 year old issue (almost to the day!) which does not
appear to have been properly resolved yet. Sad.
An input device (e.g. touch pad, key board) can be attached to
multiple handlers (/dev/mouseX, console, etc) one of which can be
evdev which provides the /dev/input/event* files.
evdev can support multiple clients on a single device, as multiple
processes can open /dev/input/eventX. The each get to see all the
events.
EVIOCGRAB is an ioctl on an evdev device which causes all events to go
to that handler, and that client, exclusively.
It is being used for two distinct purposes.
1/ Stop events going to other handlers, so that e.g. absolute touchpad
events don't get mapped to relative mouse events. Keyboard events
processed by X server don't get processed by console and control-C
kills the X server.
2/ Stop events going to any other client, so they can e.g. be mapped
and fed back into a uinput device,
So there are three levels of grab that are required:
0/ no grab : all events go to all handlers and all clients
1/ evdev grab: events only go to evdev, but can then go to any
client of evdev
2/ total grab: events only go to the specific evdev client that
requested the grab.
0 is the default
mainline allows you to select 2 but not 1.
this patch allows you to select 1, but not 2.
It seems that the "obvious" thing to do is to interpret the argument
to EVIOCGRAB to select between these options.
We cannot use 0, 1, 2 as above - despite the fact that it makes sense
- because that would be a regression: working programs would break.
Maybe it's best to use 0, 2, 1 and document it clearly. The chance of
anyone using 2 already has got to be very close to zero.
We would then need to change the drivers in the X server to use '2'
rather than '1', and (I think) everyone would be happy.
Below is my proposed patch which provides the functionality of
the patch in question without causing any regressions.
It also fixes two minor buglets in the original.
If anyone would like to comment, I'd appreciate it. If I hear nothing
bad I'll propose it to Dimitry Torokhov on some appropriate list.
Thanks,
NeilBrown

fix-glamo-turbo-host-interface.patch
Until now, we forced Glamo wait states to 3 on read and write
actions -- on the GLAMO side of the fence. This reduces them
to "0", although nWAIT is still briefly operated I saw. This
should reduce all memory bus timing by 3 Glamo Host bus clocks,
60ns at 50MHz.
In addition, until now we used PLL1 (50MHz) for host bus clock.
Now, we use PLL2 (80MHz) for host bus clock, so all transactions
complete quicker on Glamo side, it's a raw 60% improvement.
These changes do not appear to impact correct operation of Glamo
SD Card or video after testing for a week.

interface for configuring freefall/wakeup interrupts for the accelerometers
Hi!
First: Unfortunately, the freerunner currently wakes up immediately on
suspend when the accelerometer IRQ is selected as a wakeup source. I'm
posting this for comments and if someone else wants to have a look at
this problem.
The patch should be safe to apply even though the sleep portion doesn't
work - as long as it's configured it will not disturb anything.

lis302dl-configure-wakeup-interrupts.patch
From: simon.kagstrom <simon.kagstrom at gmail.com>
First: Unfortunately, the freerunner currently wakes up immediately on
suspend when the accelerometer IRQ is selected as a wakeup source.
Add configuration of wakeup/freefall interrupts through a sysfs
interface. Configuration is done through echoing a value of the
form
X Y Z THRESHOLD DURATION SPEC
to freefall_wakeup_1/2. X, Y and Z are threshold values, given as a
value > 0, < 0 or 0 to specify if an interrupt should be generated for
high or low thresholds or neither (off). THRESHOLD specifies the
threshold that must be exceeded. DURATION specifies the time in
milliseconds for which the acceleration should be measured. SPEC is
either '1' or '0' and specifies if the thresholds should be taken all
together or one at a time ('and' or 'or' mode).
Echoing '0' to the file turns off the interrupts.
Example:
echo "1 1 1 60 60 0" > freefall_wakeup_1 # Turn on x,y,z, 60ms/60 threshold, or-mode
echo "0" > freefall_wakeup_1 # Turn off interrupt
The hardware supports two simulataneous wakeup sources to be configured,
but the freerunner only connects one of the interrupt outputs. The patch
exports both. Similarly, only the "top" accelerometer can be used as a
wake-up source, and it's not possible to generate DATA_READY interrupts
while the wakeup interrupts are active.
