HDASP on ThinPad W510 - Axes totally messed up

Bjoern — Sat, 09 Apr 2011 23:19:21 -0000

Hi,
I just wanted to ask if it s possible to support Lenovo ThinkPad W510 properly.

The problem is that the directions are completely of. I tested it with
hdaps_gl and got the following:

Tilt to the left: hdaps_gl --> backward.
Tilt to the right: hdaps_gl --> front.
Tilt to the back: hdaps_gl --> right.
Tilt to the front: hdaps_gl --> left.

Since I can't code in C I failed to fix it on my own :-( and inverting
axis does not resolve this problem.
I guess the directions are not essential for HDAPS since it works
flawless, except this little cosmetic problem mentioned above.

The stock vanilla Linux 2.6.38.2 hdaps module behaves the same line after adding the W510 to the supported devices.
I reported this to the hdaps devel mailing list.

Cheers,
Bjoern

remove newline in set_inhibit_charge_minutes message

The attached patch removes an unnecessary newline in the set_inhibit_charge_minutes syslog message.

tp_smapi does not work with kernel 2.6.37

Hannes von Haugwitz — Sun, 09 Jan 2011 12:12:25 -0000

Due to the move of the hdaps driver from driver/hwmon to drivers/platform/x86
in kernel 2.6.37[1] 'make patch' fails with an error.

The attached patch fixes that issue.

The patch also includes the fixes of the compilation errors which has been
reported and fixed in debian bug #602367[2].

start_charge_thresh wrong behaviour

Anonymous — Sun, 01 Nov 2009 09:03:55 -0000

If I set the following two thresholds:

echo 40 > /sys/devices/platform/smapi/BAT0/start_charge_thresh
echo 80 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh

I get an unexpected behaviour. If the battery is below 40% when I turn on my laptop, it does not get charged at all. The expected behaviour is: the battery gets charged until 80%. I'm using a ThinkPad X200s with tp_smapi 0.40 and related hdaps (not the kernel one).

Build error on openSUSE 11.1

Radomír Černoch — Mon, 09 Mar 2009 11:58:43 -0000

Currently the Makefile contains a check to prevent compilation on kernels < 2.6.19. However this check does not work on openSUSE 11.1. I have attached a patch to repair it. It may be useful to you as well.

Can not set BAT0/start_charge_thresh

Jun Zhang — Sun, 08 Mar 2009 15:14:45 -0000

Hi,

I just install tp_smapi module on my laptop. and set the start_charge_thresh by using:

echo 40 > /sys/devices/platform/smapi/BAT0/start_charge_thresh

It is works fine at beginning. but every time when I shutdown and power on the laptop, the value of start_charge_thresh is set back the default value '96'.
it seems like system reload the smapi module when boot up and reset all the values. Can it be keep to the value I want to set?

My OS is Ubuntu 7.04 and kernel is 2.6.20-16-generic. and Laptop module is IBM thinkpad X40 2371.

thanks in advance.

Add support for x61 tablet

Bryan Hundven — Sun, 28 Sep 2008 22:55:18 -0000

The following patch adds the "ThinkPad X61 Tablet" to hdaps_whitelist[] struct in hdaps.c.

So far everything works but the drive protection (in bug: 2134778)

AHCI /sys/block/sda/queue/protect missing for X61 Tablet

Bryan Hundven — Sun, 28 Sep 2008 22:29:17 -0000

With a lenovo x61 Tablet (Product Name: 7764CTO), the ability to enable the drive protection is missing.

I have noticed this with every kernel version I have used. Currently I am using 2.6.27-rc7 and tp_smapi-0.37.

(last message repeated after readouts)

or is it because i use thinkpad_acpi module?

also, if i set start_charge_thresh it also sets stop_charge_thresh to value-1 of the start_charge_thresh.. similiarly when setting stop_charge_thresh it sets start_charge_thresh.

kernel 2.6.26.5, thinkpad x40
