I'm confused about the failure scenario you describe here, as yield() really should always allow irqs to run prior to returning. When called from a "background thread" it will not directly enable irqs, but it will always cycle through all "threads" before returning. Thus the "main thread" should always be reached and when it runs yield() it will permit irqs to run. Am I missing something? -Kevin _______________________________________________ SeaBIOS mailing list -- seabios@seabios.org To unsubscribe send an email to seabios-le...@seabios.org
