Hi All, I'm into developing OTG Controller driver for Linux for ARC controller. The only similar implementation that i could find was OMAP. Could you please clear the following doubts?
1.) In OMAP ISR, work queue is used for invoking the bottom half. Is it cumulative? If not, isn't there a chance for missing some interrupts or missing the order of occurance if back to back interrupts occur before the bottom half for the first one is executed? 2.)For passing the reason for interrupt to the bottom half, isp->todo is used. Shouldn't a lock be used because both isp1301_work() and ISR are accessing this variable? Thanks, -Suj ------------------------------------------------------- Using Tomcat but need to do more?
