| − | Great, great work! Really! This completely rocks. I just stopped my battery from charging at 77% and restarted charging a bit later, no problems whatsoever. BTW, this is on kernel 2.6.14.3.

| − | All the features except the stop_charge_thresh seem to work here on a t42p.
| |
| − | One note, the start_charge_thresh seems to really be stop_charge_thresh. Ie, If I set that to lower than my current battery %, it will never charge,

| − | Nirik, "all the features" as of which version? For example, do the force_discharge{1,2} in tp_smapi 0.12 also work for you? See the table in the article page. About start_charge, that's odd. Can you send me a log of what you did, what was the result a what was the dmesg output for each operation?

| |
| − | Ajunge, how do you compile the "thinkpad" module compile on kernel >=2.6.9? The latest thinkpad version (5.8) still uses "get_cpu_ptr" and "set_cpu_ptr", which were removed in 2.6.9.

| − | == Kernel Patch? ==
| |
| − |
| |
| − | 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. ;)

| − | If it does that on a local copy (no changes the original kernel tree) and cleans up after itself, that's fine with me. :-)

| |
| − | Ok, here's a shell script that creates the patch, feel free to use it under the terms of the GPL. For example call it from your Makefile with the patch target: (I didn't want to put all the script into the Makefile, since the rules about escaping in Makefiles, well, escape me ;)
