![]() This patch contains 2 sets of fixes for the abituguru: 1) Much improved timeout handling, drasticly reducing the amount of timeout errors on some motherboards 2) Fix the exit paths in the bank1 sensor type detect code to always restore the original settings even on an error. Without this our special test settings could remain seriously confusing the system BIOS's setup menu. Both are very much related and are must haves, to avoid messing up the uguru CMOS settings. Detailed changes: - Much improved timeout / wait for status handling. Many thanks to Sunil Kumar, for all his testing, ideas and patches! The code now first busy waits, polling the uguru for the expected status as this usually succeeds pretty quickly (within 90 reads). To avoid unnecessary CPU burn in timeout conditions, the amount of busy waiting has been halved from previous versions (120 tries instead of 250). This is not a problem, because this version goes to sleep after 120 attemps for 1 jiffy and then tries again, it does this sleep and try again 5 times before finally giving up. This (almost?) completly removes the timeout errors some people have seen regulary. Apparently some older uguru versions sometimes are distracted for a (relatively) long time. This solves this. - These timeout errors not only occur in the sending address part of reading the uguru but also in the wait for read state, so errors in this state are now handled as retryable just like send address state errors and are only logged and reported to userspace if 3 executive tries fail. - Fix a very nasty bug in the bank1 sensor type detection code, where it would not restore the original settings in any of the error paths! - Since not successfully restoring the original settings can seriously confuse the system BIOS (hang when entering the relevant setup menu), we now try restoring them 3 times before giving up.
