Hi all, I would appreciate it if people could start testing the latest ivtv on the 0.10 branch, available here:
http://ivtvdriver.org/viewcvs/ivtv/branches/0.10.tar.gz?view=tar The current driver has a problem with copying data from the MPEG card to memory that are done using PIO instead of DMA (for good reasons). Unfortunately PIO accesses are slow, so too much time is spent inside the interrupt handler. This can lead to missing clock ticks and problems with remotes (key hits that are missed). The patch I've committed moves these PIO copies to a separate handler outside the interrupt handler, so this should solve these problems. However, I did not have much time to test it thoroughly, so I'd very much appreciate it if people could start testing this and report whether or not any new problems were introduced. This patch is also queued for the 2.6.22 kernel, by the way. If this change solves the problems that I've mentioned above, then I'll make a new 0.10.3 release in two weeks time. Thanks, Hans _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
