| |
| − |
| |
| − | Hello Thinker,
| |
| − |
| |
| − | would it be possible to provide the SMAPI support as kernel patch as well? Something along the lines of: (0.12 against 2.6.15-rc5)
| |
| − |
| |
| − | ''(deleted, see below for how to create a patch file)''
| |
| − |
| |
| − | Deleted the tp_smapi.c file at the end, out of obvious reasons, and I'm not sure about the placement in the ACPI section, OTOH there it would be found easily next to ibm_acpi.
| |
| − |
| |
| − | Providing a patch would help when recompiling the kernel often, I hate recompiling external modules every time (even got me a kernel-upgrade script to do most of it automatically). But of course it's up to you. :)

| − | ----
| |
| − |
| |
| − | I'll be glad to add this, but I don't want to go through additional manual steps in the release process (there are already quite a few). Can you add a "make patch" functionality to the Makefile, or something of the sort, to automatically generate a full patch (including tp_smapi.c) against current kernel sources?
| |
| − |
| |
| − | Also, this shouldn't be under drivers/acpi, since it doesn't use ACPI at all (that's why I didn't make it a patch to ibm_acpi). I think the right place is drivers/firmware, like the dell_rbu driver for Dell laptops.
| |
| − |
| |
| − | BTW, the convention for kernel patches is to start them once level higher:
| |
| − | diff -Nurp kernel-2.6.14-vanilla kernel-2.6.14-patched

| − |
| |
| − | Of course it's from the wrong level, as usual I was just lazy/inattentive. And at one point I'll remember who likes what patch format, promise. ;)
| |
| − |
| |
| − | A patch target as in "create a new file holding a correct diff to current kernel source" would be rather difficult, since line numbers might change etc., but applying the patch should be straighforward with a bit of sed. Of course I could just do that, create a patch with the diff command and then apply the new patch file in reverse. ;)

| |
| − | Amazing! I've loaded this module in my T43 which is running SuSE 10 with the kernel of 2.6.13-15. I have three points to share:
| |
| − |
| |
| − | 1. The battery control part seems to work but has a minor problem. I set the stop_charge_threshold to 70, but the battery stops charging at 55%. Don't know why and how to fix it. :P
| |
| − |
| |
| − | 2. I don't have the cd speed control function. Here is what I have under /sys/devices/platform/smapi/:
| |
| − |
| |
| − | ./ ../ ac_connected BAT0/ BAT1/ bus@ driver@ power/
| |
| − |
| |
| − | 3. SuSE 10 doesn't have the necessary C files under .../drivers/hwmon/, I copied them from a 2.6.14.5 kernel source. Maybe it causes the two problems above. :(
| |
| − |
| |
| − | When I have time, I'll install the new kernel to see if the problems are gone and report the result.

| |
| − | 1. It should stop charging at 70, but will only ''start'' charging when remaining capacity has dipped below <tt>start_charge_thresh</tt>.
| |
| − |
| |
| − | 2. See the note about PROVIDE_CD_SPEED.
| |
| − |
| |
| − | 3. That's should be needed only for patching the HDAPS driver in order to make it compatible with tp_smapi. If your kernel (which version is it?) doens't inlude the HDAPS driver anyway, you don't need to patch....
