Re: Game controller
that being said, it's possible to write code to handle combinations of those keypresses (e.g., "all mashed down at once") separately from the individual strokes. you either need to intercept the keys at a pretty low level (scan codes) and keep track of the up and down state of every key, or you can read the keys normally and use a user-level timer to decide whether more than one has been pressed in very quick succession. paul i wrote: > the "game controller" is simply 4 separate electrical contacts with a > button large enough to push them individually or together (in some > combinations). the resulting presses are reported as keyboard > keystrokes. if i remember correctly, these buttons are bound to the > "keypad" versions of the arrow keys, i.e. KP_UP, KP_RIGHT, etc. use > 'xev' to check me on this. > > paul > > peter wrote: > > Hi, > > > > I'm interested in use of the game controller or controllers in > > place of the TouchPad or mouse.

Re: Game controller
the "game controller" is simply 4 separate electrical contacts with a button large enough to push them individually or together (in some combinations). the resulting presses are reported as keyboard keystrokes. if i remember correctly, these buttons are bound to the "keypad" versions of the arrow keys, i.e. KP_UP, KP_RIGHT, etc. use 'xev' to check me on this. paul peter wrote: > Hi, > > I'm interested in use of the game controller or controllers in > place of the TouchPad or mouse.

android on XO-4 questions
i've been playing with android on XO-4 lately. i had tried an early release, it was buggy, and i didn't have much use for it anyway, so i'd not tried the latest. it actually works pretty well. but i have some questions. i don't know if anyone with answers or experience is reading here, but i may as well start somewhere. - is it possible to get root? there's a terminal emulator pre-installed, and it's possible to browse the filesystem and do a few things, but being root would give access to more. (logs, for instance) - are the USB ports fully supported? i can't seen to get any app that exists to allow access to a USB GPS dongle to work, for instance. - has anyone gotten bluetooth audio to work? i know there's a limitation in the XO-4 hardware regarding audio -- i think stereo headsets won't work -- but can any audio work? (here's a case where looking at logs and dmesg output might be helpful) - i could probably get audio to work via an external (USB) bluetooth dongle, but a) USB devices would need to be recognized, and b), i think i'd need to disable the internal bluetooth. finally, a different sort of question: - i have exactly one app (an important one, unfortunately) in which the mapping of ctrl-ESC to emulate the android hardware Menu button doesn't work. does anyone know where that keyboard mapping is implemented? i'd happily replace the app-switcher function on the rotate button, and make it a true Menu key, instead. =- paul fox, p...@laptop.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

thanks ben! youxin wrote: - is it possible to get root? there's a terminal emulator pre-installed, and it's possible to browse the filesystem and do a few things, but being root would give access to more. (logs, for instance) There is no official root process in Android user build. But there are bunch of root tools you may can try on Android 4.3, I never tried them and not sure which secure hole they use, but they may haven't been fixed by XO-4 Android. http://forum.xda-developers.com/showthread.php?t=2565758 Alternatively, * Serial port has root access. good. i'll try that first -- sounds easiest. :-) * Rebuild Android in engineer mode gives you root access out of box. http://wiki.laptop.org/go/Android/Building/Variants * XO-4 special secure hole, boot to sugar, unpack the Android ramdisk in boot partition, change secure configuration, repack ramdisk and replace it. - are the USB ports fully supported? i can't seen to get any app that exists to allow access to a USB GPS dongle to work, for instance. Not tested, only USB mess storage is tested. I don't think USB GPS dongle will work any way since there should be a GPS hardware abstract layer for Android needs to be implemented. the GPS dongles are all just serial devices, and an app opens the serial port and reintroduces mock GPS events into the system. You Are Here GPS seems to be one such app: https://play.google.com/store/apps/details?id=com.agbooth.usbgpshl=en but the Play store won't let me install it -- claims This item is not compatible with your device. - has anyone gotten bluetooth audio to work? i know there's a limitation in the XO-4 hardware regarding audio -- i think stereo headsets won't work -- but can any audio work? (here's a case where looking at logs and dmesg output might be helpful) Assume you are talk about A2DP? It's not ported on XO-4, but HSP should work fine. okay. i've rechecked the docs for my headset, and it only mentions A2DP and HFP. so i guess i'm stuck with a wired connection. (the headset allows for a wired input as well as using BT.) - i could probably get audio to work via an external (USB) bluetooth dongle, but a) USB devices would need to be recognized, and b), i think i'd need to disable the internal bluetooth.

Power button events thus come in over the EC/Host communications --- I'm not sure these are button down/button up events. the power button does produce real down/up events, but until today, when we released new EC firmware, both down and up came right together, independent of how long the button was held. plus, the power button appears on a different input device than the rest of the keyboard, which shouldn't confuse things, but might. the new EC code produces real PRESSED and RELEASED events which the kernel now translates to to real key down/up input events. ben needed this for the android power dialog, which relies on timing the button press duration in order to pop up the menu. it's vaguely possible that this change also fixes the screenshot combo. paul =- paul fox, p...@laptop.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Instead of using a resistor, you might use two or three large diodes in series, each of which will provide a forward voltage 0.6V drop. Pick the diodes based on the maximum current 1.85A (usually double that), and the power that will be released as heat; P = V x I, where V is 0.6, and I is not to exceed 1.85A, so 1.11W minimum power dissipation. Place them in a way that does not hold the heat in. https://learn.sparkfun.com/tutorials/diodes p.s. if you find one diode does what you need, then add another in case of variation in the supply or laptop.

Fedora and most Linux distros (not to mention Macs) support mDNS out of the box, yet for some reason it is turned off in OLPC OS. I believe all that is required is the addition of the nss-mdns package to the OLPC OS build. if it's that simple, can your deployments simply do that installation with yum? or is there something else missing, either from the laptop, or from my understanding? paul Enabling mDNS allows us to add an Internet-in-a-Box network appliance to an XO deployment network with zero configuration. The user just plugs our device into their network and browser queries for http://know.local simply resolve. This works on Mac and most flavors of Linux, and for Windows we provide an NMB name at http://know. But ironically the XO seems to lack any mechanism for de-centralized local resource discovery. Unfortunately, since OLPC OS does not resolve mDNS names we are finding deployments to XO schools are much, much harder. We are, for example, right now in the middle of a deployment to a large school with XOs in Pakistan. Instead of just plugging in the Internet-in-a-Box device, the people on-site need to reconfigure DHCPd on their CentOS XS School Server to supply a static IP to our appliance's MAC address, then use the IP address from the XO's browser.

Re: minimizing footprint
i think the point john (gilmore) was making is that it's a bad precedent that simply because a) systemd offers a second-rate API for scheduling events, and b) we only have a couple of uses for an event scheduler, that we should therefore switch from a well-established API to a lousy API. instead, if systemd can be made to support the cron API properly, it would be worth making it do so. barring that, or if it's too much work (likely), then if it saves us boatloads of disk to make the switch, and our use-cases don't lose functionality or correctness as a result, then i guess we should switch. but when systemd falls out of favor in a year or two we'll just have to change things again -- either to something new, or back to cron (which will most certainly still be available). paul gonzalo wrote: On Sun, Mar 24, 2013 at 11:29 AM, Tony Anderson tony_ander...@usa.netwrote: On 03/24/2013 09:38 AM, devel-requ...@lists.laptop.org wrote: It's true, we need learn new tricks, but does not have sense have a service not needed on every xo, if we can do it in a better way.

There are any official doc about the switches I am missing? There are a

if you open the device and read it, you'll get a stream of struct
input_event structures (/usr/include/linux/input.h) representing
opening and closing of the SW_TABLET_MODE switch. here's a C code
snippet from olpc-switchd (part of powerd):
void ebook_event()
{
struct input_event ev[1];
if (read(ebk_fd, ev, sizeof(ev)) != sizeof(ev))
die(bad read from ebook switch);
dbg(3, ebk: ev sec %d usec %d type %d code %d value %d,

ev-type, ev-code, ev-value);
if (ev-type == EV_SW ev-code == SW_TABLET_MODE) {
if (ev-value)
send_event(ebookclose, round_secs(ev), ebk_device);
else
send_event(ebookopen, round_secs(ev), ebk_device);
}
}
perhaps there's an evdev to dbus gateway of some sort, but i don't know

Hi all.
A simple solution was found :)
I hacked the KP_Prior and KP_Next keys, and now they are used for
making-window-smaller and restoring-original-window-size respectively :)
so sugar takes over those keys? aren't those keys used by activities?
they're certainly useful in a terminal -- page up and page down.
Hmm.. Well a simple grepping showed that the Read activity is the only
activity that explicitly makes use of the KP_Home and KP_End keys; but
none seemed to make use of KP_Prior and KP_Next.
certainly not my call, but stealing keys which have always been
intended for activities to use seems like it shouldn't be done
lightly.
(and why do you need two keys? isn't the operation a toggle?)

All thanks to
* /usr/share/X11/xkb/keycodes/evdev
* sugar/src/jarabe/view/keyhandler.py
Just one thing I noticed when I tried to have the above keys take
effect
ONLY in ebook-mode (via the evtest --query test), that when I ran this
again and again via the suprocess module, the XO-4 behaved very
erratically. However, when I made the keys take effect irrespective of
the
test of ebook-mode, things worked cool. However, I will keep on looking
into the reason.
Thanks a ton to all :)

If you do:

There are any official doc about the switches I am missing? There
are a

to catch a event when the switch is activated, using dbus or
something
similar?
if you open the device and read it, you'll get a stream of struct

opening and closing of the SW_TABLET_MODE switch. here's a C code
snippet from olpc-switchd (part of powerd):

I tried both 720p and 1080p. i can't tell if you're not getting signal at all, or just in OFW. if the former, and you're using a B1 unit (and i assume you are), then there's a good chance that the cable isn't making contact properly. the jack is mounted just a little too far back from the edge of the motherboard, and so too far from the outside of the laptop. it's only off by a millimeter or so -- if you don't mind trimming just a bit of the rubber encapsulation from around the metal part of the micro-hdmi plug, it should help. (fixed on C1 units) if the latter, and you have signal in OFW but not linux, be sure your upgrade to q7b09 was successful. linux hdmi won't work without it. paul =- paul fox, p...@laptop.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

the offset the driver applies shifts in every spot of the screen, it's
a devilish thing.
Paul, can we crank those defaults way down? Or add a dampening / ramp
up effect to the offset that is flat in most of the screen, but
quickly ramps up near edges? (If you don't believe me, install OS5 and
use Sugar with the touchscreen for a while).
as i said the other day, the kernel driver should either do no scaling
by default, or it should make every pixel on the screen touchable with
a standard pointing instrument (i.e., a stylus). the latter is what
it does now -- perhaps exaggerated. but any other midway decision
between those extremes (which i agree is probably the right thing)
constitutes policy, and therefore belongs at user level.
which is to say, i think the correct defaults belong in olpc-utils,
along with the countless other XO useablility tweaks that are already
there.
(once that change is firmly in place, i'll probably revert the driver to
default to no scaling at all.)

Re: Migrating XO-1.75 to device tree - upgrade considerations
daniel wrote: Hi, We want to follow the upstream direction of dynamically driving hardware detection by the firmware-provided device tree, rather than hardcoding a board file into the kernel. We have in-development kernel and firmware versions that make this move, but we need to do this in a way that doesn't disrupt existing users on upgrade. These are the possible scenarios: new = whats currently in development, DT old = whats currently shipped as stable, non-DT 1. New kernel, new firmware: this is the easy case - in this scenario we upgrade both components and we know that they work together since we wrote tham that way. 2. New firmware, old kernel: This currently will not boot, because the new firmware boots with a new /chosen/bootpath value which is not recognised by the initramfs shipped with the old kernel. However, it is not clear that we do need to support this case: the requirement of running a new firmware on top of an old software base this is the case someone will be in if they install a new release, then re-install an old release. perhaps not something universally done, but is it really that uncommon? paul is not common. And the only option we'd have of fixing it is putting nasty hacks in the firmware, so if the need does arise in future, we could produce new firmware versions with the required hacks included. 3. Old firmware, new kernel: This is a case we definitely have to care about. When system updates are done in the field, it is not guaranteed that electricity will be available upon the reboot in order to install the updated firmware. So we need to keep this case working. (We know this is an issue because we've pushed OS updates dependent on new firmwares before, then we had to revert that upon realising the field difficulties). So #3 is the only case that needs our special attention at the present time. The issue here is that the old firmware does not present a good-enough device tree to the kernel, and the new kernel does not have the old/static XO-1.75 board definitions. The system won't boot - some corruption appears at the bottom of the screen, and nothing appears over serial. Ideally we want a solution for this that will hold for the long term - i.e. its something we'd ship for considerable years to come, not only just for the next release, to provide a direct upgrade path from the software releases of today to any release of the future. Options include: 1. Ship the static board file in the kernel, or maybe a cut down version of it. I'm not so keen on this - we'd have to keep the non-upstream kernel code around forever. 2. Append the XO-1.75 device tree to the kernel image. This is my favourite option - while we would have to duplicate the DT (once in the firmware, once in the kernel), at least they can be direct copies rather than two different approaches to maintain. (can the kernel be made to use this only when a good DT is unavailable? Maybe the definition of good DT is hard to define - I'm referring to the fact that we already ship a DT, but not one that can be used to get the system on its feet in the absence of a board file) 3. Somehow detect this case and print a warning message. Not so keen on this myself - expressing this in kid-friendly language seems challenging, then there's internationalisation and so on.

I doubt it, but I've not had a moment to try it. We don't have a need for absolute time wakeup in the OLPC OS builds. i'm not sure i've tried an absolute wakeup time either, but i know of no reason it shouldn't just work. as james implies, the complication for george's scheme is that our power management daemon (/usr/sbin/powerd -- it's a (large) shell script, so feel free to take a look) uses the RTC itself, so it's likely that a user's setting of the RTC will be lost in somewhat short order. i'm sure powerd could help make what you want to do easier than it is now. please let me know if you'd like to continue working on this. there's one more wakeup timer available, implemented as a delta timer in milliseconds (32 bits, or at least 31), that's in the EC. we don't use that during normal operations with powerd, so it might be useful. we've talked about having powerd use that, rather than the RTC, but there are some technical details that prevent that at the moment. paul You can easily use a delta time sleep until the clock is close to start of school day.

Re: Kernel development setup for XO-1.75
martin wrote:
{ Maybe someone can polish it further and put it into a wikipage. Note
that the process and tools change over time a bit... }
Hi new kernel developer,
Here are some hints, meant for a self-sufficient kernel developer to
find her/his own way. Some you may know already :-)
- You will want to be on devel@lists.laptop.org for general hacking
questions. This is an open list, so no NDA topics. You will see build
announcements there.
- We also use irc -- #olpc-devel on OFTC
- You need to know how to download and install a build (grab the zd
file, look in the install instructions for fs-update).
- You will want to have your XO setup with a serial port - search our
wiki for the Serial adapter page...
- The kernel that _actually_ boots is in /bootpart/boot/vmlinuz, it
then uses an initramfs that invokes dark magic before it invokes a
normal userland. You can only boot into a usable system through this
magic initramfs.
Our current development practice is to provide a kernel via USB (or
even WLAN) so
that the XO ignores the one on the internal disk. Put the attached
olpc.fth file in a FAT formatted USB, inside a boot directory. Then
put a zimage file in the root of the USB disk.
[ alternatively, you can simply install your kernel in /bootpart/boot,
and adjust the vmlinuz symlink accordingly. if you do this, and
your kernel config is _not_ monolithic, then you'll need to have
put a copy of your modules under /usr/lib/modules. if you need
to make booting changes (i.e., adjust kernel commandline, etc), you'll
edit /bootpart/boot/olpc.fth. ]
This olpc.fth file controls the boot process, you can tweak boot
parameters in there, or tell it to boot a kernel fetched via http over
wlan. It is written in Forth.
- You'll want our git tree: git://dev.laptop.org/olpc-kernel -
master there follows Linus' kernel. We are currently working on
arm-3.0-wip
for XO-1.75.
- Our defconfig file is in arch/arm/configs/xo_175_defconfig. I
normally copy it to .config and then perl -pi -e 's/=m/=y/' to make a
monolithic kernel that Just Boots.
- We currently crosscompile our kernels for development --
if you're running ubuntu/debian, you can simply
apt-get install gcc-arm-linux-gunabi
and set ARCH=arm and CROSS_COMPILE=arm-linux-gnuabi- before
running make as usual. otherwise, you'll want to untar, as described
below.
paul
Untar http://dev.laptop.org/~cjb/gcc-4.6.0-from-x86_64-to-armv7.tar.bz2
to /opt, then
PATH=$PATH:/opt/crosstool/gcc-4.6.0/bin/
make ARCH=arm CROSS_COMPILE=armv7-unknown-linux-gnueabi- your make
target here
- We have an autobuilder that makes nice RPMs of the kernels based
on our git branches. Once you have a well tested patch, spam someone
in our team to get it into the official git repo so that it gets into
our RPM'd kernels...
This is merely a start.

Re: [PATCH powerd] Fix config_SLEEP_WHEN_LID_CLOSED
sascha wrote: Since 792c7dd3 powerd stays asleep by default while the lid is closed. That's important for some use cases (putting suspended laptops inside a charging rack), but breaks config_SLEEP_WHEN_LID_CLOSED=false unless the new configuration option config_WAKE_WHEN_LID_OPEN has been explicitly set to true by the user. As this option isn't present in the configuration file where powerd was updated rather than freshly installed, it takes them some time to figure out why config_SLEEP_WHEN_LID_CLOSED doesn't work anymore. Since the user has no expectation of the laptop going to sleep at all when closing the lid if config_SLEEP_WHEN_LID_CLOSED is set to false, it's safe to always enable config_WAKE_WHEN_LID_OPEN in that case. if config_SLEEP_WHEN_LID_CLOSED is false, the user presumably used the power button to put the laptop to sleep. i'm not sure why they should expect it to wake on lid open. i appreciate the issue for a user that's done an upgrade, but i'm not convinced that having sleep-on-close == false should imply wake-on-open == true. perhaps i'm missing a subtlety. paul Signed-off-by: Sascha Silbe si...@activitycentral.com --- powerd |3 +++ 1 file changed, 3 insertions(+) diff --git a/powerd b/powerd index a9bba10..657744e 100755 --- a/powerd +++ b/powerd @@ -2543,6 +2543,9 @@ read_config() wake_on_open=$(yes_or_true_to_boolean $config_WAKE_WHEN_LID_OPENED) +if [ -z $sleep_on_close ] ; then +wake_on_open=true +fi } battery_shutdown() -- 1.7.10 =- paul fox, p...@laptop.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

inhibiting suspend for longer than necessary, that's a problem on its own

There are many other ways of Activities misbehaving and consuming a lot of
resources. The increased battery drain by inhibiting suspend is easy enough
for users to observe by watching the power LED.

thanks for doing all that testing!
i'm perfectly happy to enable this, if we think it fixes the problem
well enough, and/or we think the applications can be fixed to do the
right thing. (for some reasonable value of we.)
in searching for a relevant ticket on d.l.o. just now, i found #6670,
which is quite relevant, if perhaps a bit dated. the issue with
Distance, in particular, isn't relevant because i believe Distance
actively suppresses idle-suspend when a measurement is in progress.
but it does raise the issue that the current check used by that patch is
an instant in time check, which really isn't optimal. an activity
counter would work (as is used for some other powerd measurements), or
better, a timestamp, as was proposed by cjb in the ticket.

i've played with this a bit more, including taking a further look
at the driver.
1) i think we should expand the expression to:
egrep -q 'RUNNING|DRAINING' /proc/asound/card0/pcm0?/sub0/status
2) i tried the inotifywait trick mentioned in #6670. inotify picks up
open and close events on the device, which could aid in knowing
when the device was used, but it doesn't pick up on the data
writes because they're often done with
ioctl(SNDRV_PCM_IOCTL_WRITEI_FRAMES,...) instead of write(). so i
don't think that's useful.
3) as far as the activity testing you did, i agree with your results
-- i didn't try everything, but Scratch is certainly the biggest
violator, in that it keeps the device in RUNNING state even when
not playing anything, and when not in the foreground. observed
with strace, Scratch actually continuously writes (using ioctl())
to the device. perhaps someone could work with the scratch
authors on this?
the browsers do seem to let the device out of RUNNING state,
though as you noted they do still prevent others from using the
audio device (a separate problem). the TamTam family isn't great
either.
this is all just further data. i'm really not in a position to
say what the goal should be for powerd and audio for 12.1 or 12.2.

It's quite a difference with a typical touchpad on bigger laptops, and although the experience can't be duplicated because we can't expect kids to be already highly trained with a touchpad, I think it could be improved. I think the balance is to have a larger threshold, so that slow movements are allways acurate, and a higher acceleration, so that movements across the screen are sufficiently fast (very important in Sugar to access the frame for example). Managing to drop down the amount of swipes needed to move across the screen (like 2 swipes) would be excellent and more in par with the older pre 11.3.* behavior. so you think it was better, previously? i wonder what has changed. those xset values were chosen specifically to be appropriate for the original ALPS touchpad on XO-1. it's entirely possible, now that we're two laptops and at least as many touchpads beyond that, those numbers are incorrect. I meant to compare between the setting of the builds back in 2008 and 2011 when I began using the XO after a hiatus of years. I found a discussion started about the change from acceleration 7/4 threshold: 1 to acceleration 7/4 threshold: 0) (http://lists.laptop.org/pipermail/devel/2010-January/027245.html ). A few messages later, it's shown in xset man page: If the `threshold' parameter is provided and 0, the `acceleration' parameter will be used in the exponent of a more natural and continous formula, giving precise control for slow motion but big reach for fast motion, and a progresive transition for motions in between. Recommended `acceleration' value in this case is 3/2 to 2, but not limited to that range Which is exactly what I was looking for. A bit later, Richard A. Smith tells: 2 of the apps that our deployments spend a lot of time in are scratch and etoys. Both of these are not completely sugarized apps and thus some of the UI elements on the 200 dpi screen are quite small and hard to use with a fast accel. Though I don't know if he used higher acceleration values, or with threshold set to 0. So the thread ends with: Find someone with kids and figure out whats the best settings for them. Next time I am with my nephews I'll be sure to do this, but I already find threshold 0 a lot better. Perhaps the problem Richard was having could be solved with a lower acceleration, like 3/2, but still with threshold 0. i'm sure you're right, and i think we had consensus around that several years ago. it's my belief (after skimming old mail) that the very earliest X servers shipped on XO-1 a) did treat a threshold of 0 as special, but b) did not do it correctly. so using '1' at that time was deliberate. but after a time we (i, certainly) agreed that we should be using 0. we also had a discussion about lowering the 7/4 -- at the time i thought 3/2 was too slow, and suggested 165/100, but i suspect that that's splitting hairs. (i.e. 1.5 vs. 1.65). after verifying, we should at least fix the '0' threshold as a bug, in 12.1.0. If it's to be fixed, can't it be changed for the upcoming 11.3.1 as well? it's getting a little late for 11.3.1. P.S.- is there a script that is run when Sugar starts where I could place the xset command? So that I could the new 0 threshold setting run automatically, and thus use it without thinking about it and be able to get a better feeling of the behavior. i think /usr/bin/olpc-session is what you're looking for. note that this runs for both sugar and gnome. paul Eduardo =- paul fox, p...@laptop.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
