Does kernel have something like "sleepy task" interface, e. g. special mode that is triggered by some sort of interrupt and instead of going to perform full resume, it just lets a hook to wake up "manually" needed devices, perform the "sleepy task" and then tell the system whether full resume is requested? It can fit for Zaurus battery charging monitoring - timer interrupt needs to wake just the SPI bus. But I can imagine a GPS logger using such interface to save energy - serial interrupt semi-wakes the system each second, but will not go to do full resume. It just processes NMEA sentence and buffers the result. Only if buffer becomes full, it issues full resume and writes data somewhere. -- Best Regards / S pozdravem, Stanislav Brabec software developer --------------------------------------------------------------------- SUSE LINUX, s. r. o. e-mail: sbra...@suse.cz Lihovarská 1060/12 tel: +49 911 7405384547 190 00 Praha 9 fax: +420 284 028 951 Czech Republic http://www.suse.cz/ _______________________________________________ Zaurus-devel mailing list Zaurus-devel@lists.linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/zaurus-devel
