From ecb73774e5f5b5f635a70073086c3f57b4ca4ae6 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 17 Mar 2006 20:54:32 -0300 Subject: V4L/DVB (3545): Fixed no_overlay option and quirks on saa7134 driver Some chipsets have several problems when pci to pci transfers are activated on overlay mode. the option no_overlay allows disabling such feature of the driver, in favor of keeping the system stable. The default is to use pcipci_fail flag defined on drivers/pci/quirks.c. It also allows the user to override it by forcing disable overlay or forcing enable. Forcing enable may generate PCI transfer corruption, including disk mass corruption, so should be used with care. Added a text description to this option and make messages looks the same at both bttv and saa7134 drivers.
