Smart Battery System for Linux / News: Recent posts

Fortunately for all users of the Smart Battery stuff, there's now no longer any need to mess around with patching your DSDT. Based on a much-fixed-up version of kernel code that I developed as a proof-of-concept (before I turned to the DSDT patch approach implemented here), the 2.6.18 Linux kernel now incorporates a module that handles all of the Smart Battery stuff. This module wholly replaces the SBS-CM patches, and therefore there will not be any further development of these patches.

I'm pleased to announce that, after quite a long period of inactivity, I've finally managed to grab enough spare time from the real world to bring the SBS-CM (Smart Battery System/Control Method) project up to date.

Those relying on this project to check their battery status (primarily on Acer laptops) can now grab the sbs-cm-20051112 release. I haven't made any changes to the DSDT stuff; however, I've included new patches for replacing the spinlock mutexing in the embedded controller (EC) driver with semaphore mutexing. In addition to the kernel 2.6.10 and 2.6.11 patches included in previous releases, I now provide patches for 2.6.12. 2.6.13 and 2.6.14 kernels. I intend to offer a 2.6.15 patch once this kernel version becomes the current version.... read more
