From e65320dd8af749a0fe8242b59921b56d4eaf8d27 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 19 May 2007 19:07:16 +0200 Subject: Move big PIO accesses from the interrupt handler to a workhandler From: Hans Verkuil Sliced VBI transfers use PIO instead of DMA. This was done inside the interrupt handler, but since PIO accesses are very slow this meant that a lot of time was spent inside the interrupt handler. All PIO copies are now moved to a workqueue. This should fix various issues with missing time ticks and remote key hits.
